I recently purchased a B2150 4WD, hydrostatic trans with a bucket loader on the front. Tractor runs well but has two different sized front tires. Both are 6x12 R tires but one is 22 inches tall and the other is about 24 inches tall. what is the correct diameter that should be on it? Not much luck looking up new tires with a kubota part number as they are over 5 hundred dollars. Any one know of a replacement tire that works for this tractor. I dont use the 4 wheel drive unless im stuck in 2 wheel drive and just noticed the difference in tire size.

Determining the proper size is more of a matter of keeping the ratio correct between the front and rear. The ratio for a b2150 is 1.697. So divide rear diameter by front diameter. So assuming you have the 12.4-16 rear which has a diameter of 37.6 (using 1 tire spec I found online, yours may vary) then the 22" tire would be correct at 1.70. Unfortunately each tire manufacturer is different so you'll have to research each one. Rolling circumference is supposed to he the best measurement to use.
Ideally a 1-5% lead on the front. You don't want any lag. So basically the fronts could be a hair bigger but not smaller
