Kubota B2920 tire size - turfs

[gabrichter]

Decided on Turf for my Kubota B2920 now they offer two sizes to make more decisions on like I said 60% mowing 40% blowing/pushing snow, loader work and garden tilling Kubota offers FRONT - 22.0 x 8.5-12 /REAR - 31 x 15.5-15
FRONT - 23.0 x 8.5-12 /REAR - 33.0 x 12.5-15. My initial thought is get the taller tires, any pros or cons? the rear 31's are 15.5 wide and the 33's are 12.5 wide.
I see tirechains has chains for both rears but fronts only the 23x8.5-12's

Maybe you are already aware of this, but the reason for the two different sizes is that they have different tread patterns. The set with 33" rear tires are what you would see on most tractors, just a standard turf tire. The 31" set is a 'Bar/Turf' tire, which is a little more aggressive in the center, but still wide to provide flotation. If you search for 'bar turf' on here you should find some pics of both Kubota and Deere tractors equipped with them.
