oh, you definitly are going through wheel bearings.. unless you have rockwells...... these tires are roughly 50 inches high, and 22 inches wide...... and, where they are for loaders/graders, rocks arent going to cut them like a bogger or tsl would either..... but, dont expect much sidewall flex...... besides that, they come with nearly 60/32nds of tread.... tromping the tread depth of any dot legal mud tire by almost 2/3rds..... and at the price of only 700 a piece.... and they are made right here in the usa, in the topeka,kansas off road tire factory.... each one made by hand, taking any where from 5 days, to 2 weeks.
