Tractor tire types; advantages and disadvantages.

[jeff9366]

I have a Kubota L5740 it has 475/65/D20 grass tyres that need replacement. I would like a more robust tyre as seldom used on lawns. Struggling to find anything but grass tyres to fit. A advice welcome.

Scotland is a wet part of the UK.

Tall R1/agricultural tires will give your tractor the best traction running over moist / wet soil. R1 tires are almost always the choice for 2-WD tractors. R1 tires are almost always 4-ply. The flexibility of 4-ply construction improves traction. R1 tires are the least desirable tire to run over the road. R1 tires vibrate and wear rapidly on the road. R1 tires are usually the cheapest tractor tire choice.

R14 tires are a new design in the last five years. The tread pattern falls mid-way between R1 and R4 treads.

R4/industrial tires. Usually 6-ply rear tires, 6 to 10 ply front tires to support heavy FEL loads. Best tractor tires for highway travel.
Poor tire selection when traction is needed pulling over mud or wet soil. I live in a part of Florida where mud is never a factor. Most tractors in Florida are equipped with R4 / industrial tires.
R4 tires are more expensive than R1 tires.

Scotland is a wet part of the UK. True, but rather like saying Death Valley is a dry part of the desert.

R1 4 ply is your softest riding and best traction......BTDT
