Understanding Kubota Tire Sizes
Kubota tractors use various tire configurations based on:
1. Tractor Size and Weight – Smaller BX and B-Series models use shorter and narrower tires to keep the center of gravity low, while M-Series models use taller and wider tires for traction and load capacity.
2. Front vs Rear Tires – Rear tires are larger for traction and load distribution. The front tires are smaller for steering precision and balance.
3. Tread Type – Kubota offers:
- R1 (Agricultural) – Deep lugs for field traction and muddy conditions.
- R3 (Turf) – Smooth tread pattern to reduce grass damage.
- R4 (Industrial) – Hybrid tread for construction, loaders, and mixed surfaces.
4. 2WD vs 4WD Models – Four-wheel-drive tractors require precise front-to-rear tire circumference ratios. Incorrect sizing can cause drivetrain stress.
5. Load and Ply Rating – Always match or exceed the original load rating. Heavier implements or loaders may require reinforced sidewalls.

Tips for Selecting the Right Tire
- Check your operator’s manual for manufacturer-approved tire dimensions and pressures.
- Inspect your current tires for the printed size on the sidewall before ordering replacements.
- Maintain proper air pressure, underinflation causes uneven wear, while overinflation reduces traction.
- Choose tread type by task: Turf for lawns, AG for farming, and R4 for construction.
- Always replace in pairs (front and rear) if the tread or rolling circumference differs significantly.
- If upgrading to radial tires, verify rim compatibility and clearance.
Why Kubota Tire Sizes Matter
Using the correct tire size maintains transmission ratios, steering balance, and ground contact. Incorrect front-rear tire matching in 4WD models can lead to drivetrain binding, premature wear, or traction loss. It can also affect ground clearance, PTO angle, and loader stability.
Additionally, tire choice directly affects ride comfort and efficiency.
Turf tires provide smoother rides, while AG tires increase pulling power in muddy or soft ground. Industrial tires offer durability on hard or rocky surfaces.
Final Thoughts
Kubota’s diverse lineup of tractors and utility vehicles requires equally diverse tire setups. The chart above offers a quick reference to typical factory-equipped sizes across Kubota’s BX, B, L, MX, and M series, plus RTV utility vehicles and mowers.
When replacing or upgrading your Kubota tires, always consult the owner’s manual and choose tires that fit your work type. Matching tire size, tread pattern, and ply strength ensures better traction, longer lifespan, and safer operation for your machine.
