The single most common question Kubota buyers ask after picking a model is which tires to put on it. R4 industrial, R1 ag, or turf — and the answer matters more than most people realize. Pick the wrong tire and you’ll either be tearing up your lawn every time you mow, spinning out in mud when you need traction most, or punching through turf tires on gravel and nails every other season. This guide breaks down every tire type in plain terms so you can match the right tire to your property, your tractor, and how you actually use it.

The Three Tire Types — What Makes Them Different

R4, R1, and turf tires differ in three fundamental ways: tread aggressiveness, sidewall strength, and how they balance traction against turf protection and pavement manners. Get these three variables right and the tire choice becomes obvious for your situation.

R4 Industrial Tires

R4 industrial tires are built for construction and mixed-use work — loader operation, gravel driveways, dirt, hardpack, and occasional mowing. The tread pattern features wide bar lugs at moderate depth with closer spacing than R1. A Titan Trac Loader R4 in 26×12-12 runs 16/32 bar depth as a reference point. The sidewalls are thick and stiff for puncture resistance and heavy loader loads — the most puncture-resistant of the three types. On hard surfaces R4 provides the best wear and stability of any tractor tire. In soft ground the shallower, closer-spaced lugs can pack with mud sooner than R1. On grass the damage is moderate — far gentler than R1, rougher than turf, but most compact owners report very acceptable lawn impact when driven with some care.

R1 Ag Tires

R1 ag tires are purpose-built for field work — plowing, discing, tilling, subsoiling, and pulling heavy ground-engaging implements in soft soil. The tread pattern uses tall, narrow, widely spaced chevron bars with roughly 1 to 1.5 inches of bar height on typical farm tractor sizes. The sidewalls are relatively flexible to enlarge the footprint at lower pressures, though on light compact tractors they often need to be run harder for loader work, which stiffens the ride. On hard surfaces R1s wear fastest and ride roughest of the three — the lugs squirm and can feel unstable on pavement. In mud and soft ground they dominate: forum owners consistently report R1s will go where R4s stop. On grass they are the most destructive option, rutting and tearing sod quickly especially in turns or when wet.

Turf / R3 Tires

Turf tires are designed for mowing and turf applications — lawns, estates, parks, golf courses, sports fields. The tread is shallow and densely patterned with blocks or multiple ribs, much shallower than R1 lugs. The sidewalls are lighter and softer than R4, optimized for a smooth ride and wide footprint rather than maximum puncture resistance. On hard surfaces turf tires provide the smoothest ride but wear faster than R4 under heavy loader or road use and are more vulnerable to punctures from sharp debris. In real mud they clog quickly and traction drops sharply. On grass they are far and away the best option — designed specifically to minimize rutting and visible tread marks.

R4 Industrial Tires — Full Deep Dive

R4 is the default recommendation from most Kubota dealers for BX, B, and L series owners who do any mix of loader work, gravel maintenance, and mowing. That reputation is well earned, but it comes with trade-offs worth understanding before you commit.

Best Use Cases

R4 excels on mixed properties with loader work — FEL operation, pallet forks, gravel driveway maintenance, dirt work, landscaping, and light brush hogging. If your property has some lawn plus gravel, woods roads, or construction activity, R4 is typically the right call. Multiple dealers and forum veterans describe R4 as the default compromise tire for BX, B, L, and LX size machines.

Traction Performance

In mud, R4s are described as “ok but not great” — they work in light mud but pack up quickly in sticky clay and lose drive where R1 keeps going. On wet grass they provide noticeably better traction than turf in dry and firm conditions, but can slide on wet grassy slopes where some owners chain them for serious hills. In loose dirt, Messicks’ load-cell testing showed R4 had approximately 30% better drawbar pull than turf — a meaningful real-world advantage for loader and grading work.

Turf Damage Reality

On BX, B, and L tractors, R4s don’t tear up grass significantly when driven carefully — avoiding tight turns in 4WD, staying off saturated ground, and keeping speeds reasonable. On tight turns, damp lawns, or when spinning, they will mark turf more than R3. But for most compact owners splitting time between mowing and real tractor work, the trade-off is very manageable.

Durability

R4 is the durability champion of the three types. One owner on NewAgTalk reported over 1,100 hours with bar code still visible on R4 lugs in compact utility service. The thick sidewalls also mean far fewer punctures from gravel and debris compared to turf tires.

Popular R4 Models for Kubota Compacts

The Titan Trac Loader TL R4 in 26×12.00-12 is one of the most widely used rear R4 tires on BX and B series machines, with 16/32 tread depth and a load index of 101 (1,780 lbs at 20 psi). The Carlisle Trac Chief R4 in 26×12.00-12 is another popular option widely used on BX and L size tractors. Many L series compacts also use industrial HF-1 style tires on the fronts.

R1 Ag Tires — Full Deep Dive

R1 is the correct tire when traction is the priority and lawn appearance is not. Understanding when that trade-off makes sense is the key to not regretting your choice six months later.

Best Use Cases

R1 dominates in primary field and farm work — plowing, discing, tilling, subsoiling, and heavy ground engagement. Muddy fields, bottom ground, steep dirt slopes, and woods roads where traction and self-cleaning matter more than lawn appearance are where R1 earns its reputation. For larger utility tractors doing row crop, hay, and field work, R1 is simply the correct default tire.

Traction vs R4 — How Big Is the Gap?

In mud and soft ground the gap is significant. Owners in wet regions consistently report R4s are “pretty much useless” in wet clay where R1 keeps working. In loose soil and fields, R1 provides more pulling power and better self-cleaning, with some studies showing improvements up into the high teens in percent over less aggressive designs. On pavement, R1 loses hard — front R1s on compacts used for significant road and loader work can wear to near-slicks in a few hundred hours. The lug squirm on hard surfaces also makes them feel less stable than R4 or turf at road speeds.

R1 on Compacts — Is It Overkill?

R1 is not overkill if you regularly work in mud, fields, or on steep dirt slopes — in those conditions it’s the right tire. It becomes the wrong choice on a compact that mainly mows lawn and runs a loader on gravel or pavement. Those owners typically regret the harsh ride, rapid pavement wear, and lawn damage. The key question: does your primary tractor work involve soft ground engagement, or is it mixed use on firmer surfaces?

Which Kubota Models Come Standard with R1

The L series (L2501, L3301, L3901) ships with AG/R1 as the standard tire — 7.2-16 front and 11.2-24 Titan Hi Power Lug rear on the L3301. B series (B2301, B2601) also lists AG/R1 as the standard in Kubota literature with turf and R4 as options. The BX1880 offers turf or bar (R1) only — no factory R4. Larger M series tractors are predominantly R1 standard.

Turf / R3 Tires — Full Deep Dive

Turf tires are misunderstood by many compact owners who think they’re “weak” or can’t handle real work. They can — with the right expectations and proper ballast. The problem is when they’re put on tractors doing work they were never designed for.

Best Use Cases

Turf tires are purpose-built for primary mowing on established turf — lawns, estates, parks, and golf courses. Properties where lawn appearance and minimal rutting is the top priority and heavy ground engagement is rare. Light snow plowing on level asphalt or concrete can also be handled well with turf tires plus chains.

Can Turf Tires Handle Loader Work?

Yes, but with caveats. Many BX and B owners do light loader work on turf tires with proper ballast and thoughtful operation. For frequent heavy loader work, R4 or R14 is strongly preferred due to stronger sidewalls, better puncture resistance, and better dirt traction. Messicks’ testing showed R4 has approximately 30% more tractive pull than turf in dirt — a real gap when you’re pushing material. That said, turf and R4 performed nearly identical in their snow traction test, which surprises most people.

The Puncture Problem

The biggest real-world complaint about turf tires on compact tractors is punctures. Multiple TractorByNet owners report constant punctures from nails and sharp objects on properties that mix lawn with construction activity or gravel. If your property has any significant gravel, debris, or sharp objects in the work zones, turf tires will cost you in repairs and downtime. Consider adding tire sealant preventively.

Popular Turf Models for Kubota

The Titan Multi-Trac R3 is Kubota’s OEM turf option on several models — the 13.6-16 Titan Multi-Trac TL is listed as the turf option on the L3301 spec sheet. The Carlisle Versa Turf R3 series in 24-12.00R-12 is a popular aftermarket choice, advertised with approximately 60% deeper tread than standard R3 for better durability.

Per-Model Recommendations — Which Tire for Your Kubota

BX1880 — Turf or R1 Only

The BX1880 is the one model where R4 is not a factory option — Kubota offers turf (R3) or bar (R1) only on this machine. For the BX1880’s primary use as a residential mowing and light loader tractor, turf is the right call for most owners. Add chains for any serious winter work. Only choose R1 bar tires if your property has significant mud or ground engagement work and you can live with the lawn impact.

BX2380 and BX2680 — R4 or Turf

Both models can be ordered with R1, R3, or R4. Dealers report selling R4 or R14 on the majority of BX2380 and BX2680 tractors for mixed-use owners. If mostly lawn mowing with occasional light snow: turf. For mixed mowing plus loader work, gravel, or snow plowing: R4 or R14. For very muddy or steep woods work where you rarely care about the lawn: R1 bar tires.

BX23S — R4 Standard

The BX23S TLB is predominantly sold with R4 or R14 industrial tires, which makes sense given its backhoe and loader-focused design. Turf tires are available but R4 is the correct choice for a machine doing dedicated digging and loading work. Owner feedback on OrangeTractorTalks confirms good traction and acceptable turf impact with R4 on the BX23S.

B2301 and B2601 — R4 for Most, R1 for Farm Work

Kubota lists AG/R1 as the standard with turf and R4 as options on the B series. In practice, many B2601 owners choose R4 as the best all-rounder — good traction for the loader and ground work the B series handles well, with acceptable turf impact. Choose turf only if you primarily run a mid-mount mower and rarely use the loader in dirt. Choose R1 only if you have significant tillage, muddy conditions, or little lawn to protect.

L2501, L3301, L3901 — R1 Standard, R4 for Mixed Use

All three ship with AG/R1 as standard. If you’re doing small farm work — tillage, hay, ground engagement on a regular basis — stay with R1. If your property is mixed acreage with loader work, brush hogging, gravel, and occasional mowing, upgrade to R4 or R14. The L series is heavy enough that R4’s slightly lesser mud traction is rarely a problem with proper ballast. Estate-type properties with large lawns and light tractor work can go turf, but most L series owners have enough real work to justify R4 at minimum.

LX2610 and LX3310 — R14 or R4

The LX series typically offers R1, R3, and R14 hybrid as primary options, with R4 also available. R14 is widely recommended for LX owners because the LX’s premium feature set attracts mixed-use buyers who want better traction than turf without the full aggressiveness of R1. One LX2610 owner on Reddit with R14 tires reported excellent performance across mowing, snow plowing, digging, and grading on 24 acres. If R14 isn’t available, R4 is the next best choice.

What About R14 Hybrid Tires?

R14 is a hybrid tire that sits between R4 industrial and turf — it has more tread depth and aggressiveness than turf but less than a full R4. It’s designed for the exact buyer profile that describes most compact Kubota owners: mixed use with both mowing and real tractor work. Several dealers and forum veterans now recommend R14 as the first choice on BX, B, and LX series tractors for this reason. If your dealer offers R14 as an option and your use case is genuinely mixed, it deserves serious consideration before defaulting to R4. The trade-off versus R4 is slightly less puncture resistance and slightly less traction in demanding conditions — but better turf protection and smoother ride.

Switching Tires — What It Costs and What to Know

Cost to Switch

Replacement tire prices for typical compact Kubota sizes run roughly $240-$260 per tire for a 26×12.00-12 Carlisle Trac Chief R4. Similar-size turf or R1 tires in 26×12-12 fall in the $180-$260 range per tire depending on brand and ply rating. Full sets of four tires on BX and B series typically run $700-$1,200 or more for tires alone, plus mounting. Larger L and LX sizes run higher.

Do You Need New Rims?

Swapping within the same nominal size — for example 26×12-12 turf to 26×12-12 R4 — typically uses the same rims and many BX owners do this. Changing between R1 and R4 on B, L, and LX series may require different rim sizes or offsets because AG tire sizes use inch designations (11.2-24) while industrial sizes use different designations (15-19.5), and these are often sold as complete wheel and tire packages. Always confirm rim compatibility before ordering tires only.

The 4WD Rolling Radius Warning

Liquid Ballast — Strongly Recommended

R1 and R4 rear tires are commonly filled with liquid ballast — beet juice, RV antifreeze, or dedicated ballast products — to improve traction and stability, especially with a front-end loader. Forum consensus is to fill rear tires regardless of type whenever running a loader. Turf tires can also be ballasted but have lower load ratings and thinner sidewalls — respect the max PSI and load specs carefully. Adding liquid ballast requires tractor-specific valve stems designed to handle liquid fill without corroding or clogging.

Tire Chains — The Traction Equalizer

Here’s the finding that surprises most people: chains add more traction improvement than switching tire types for snow. Multiple forum users and the Messicks snow traction test both confirm that chains on any tire type outperforms unchained alternatives. The implication is significant — if you’re buying R1 mainly for winter traction, you’d often be better served by R4 plus chains than R1 without chains.

Can Turf Tires Use Chains?

Yes — many BX and B owners run 2-link ladder or diamond chains on turf rear tires for winter. Proper sizing and tensioning are important to avoid sidewall damage, and lower speeds are recommended. Turf tires with chains often provide excellent snow and ice traction because the flat, wide profile supports the chain across more surface contact area.

Chain Styles by Tire Type

For turf tires, ladder or diamond chains with 2-link spacing are the standard choice. V-bar only if you have significant ice and accept more potential for pavement wear. For R4, ladder or diamond chains work well — V-bar is popular on gravel and ice applications, and the squarer shoulder of R4 gives good chain seating. For R1, ladder or studded chains for deep snow and woods; spacing is often adjusted to sit between the aggressive lugs.

Common Questions and Misconceptions

“Can R4 tires damage my lawn?”

Yes, but usually not enough to matter if you drive sensibly. On BX, B, and L size tractors, owners consistently report minimal damage with R4 when avoiding tight turns in 4WD, staying off saturated ground, and keeping speeds moderate. You will see more imprint than with turf tires on a manicured lawn, but for most owners the trade-off in traction and durability is worth it. If your lawn is a golf course, choose turf. If it’s a working property with a lawn, R4 is fine.

“Are R1 tires overkill for a compact tractor?”

They are not overkill if you regularly work in mud, fields, or on steep dirt slopes — those are exactly the conditions R1 was designed for. They become the wrong choice on a compact used mainly for mowing and loader work on gravel or pavement. The harsh ride, rapid wear on hard surfaces, and lawn damage are real costs that many compact owners underestimate when they order R1 for maximum traction.

“Do turf tires work for loader work?”

They can handle light loader work with proper ballast and careful operation. For frequent or heavy loader work — pushing material, filling a spreader, moving brush — R4 or R14 is strongly preferred. The sidewall strength and dirt traction difference becomes very real when you’re consistently working the loader hard in anything other than light soil or mulch.

“Which tires come standard on Kubota BX and B series?”

The BX1880 offers turf or bar (R1) only — no factory R4. The BX2380, BX2680, and BX23S offer turf, bar (R1), and industrial (R4) with dealer practices varying widely. B series (B2301, B2601) lists AG/R1 as standard in Kubota literature with turf and R4 as factory options. Many buyers upgrade to R4 at time of purchase. Always confirm what’s on the specific unit before you take delivery.

“Can I mix different tire types front and rear?”

You must keep matched rolling-radius sets front and rear per Kubota specs — mismatched combinations can damage the 4WD drivetrain. Some mixed combinations (different types, same rolling radius) are sold as approved factory sets. Do not mix sizes or types on your own outside of factory-approved combinations.
