Wierd question

[Kain]

i had to buy used tire for up front there 32 10.5 15 there 33 12.5 15 on the rear when i put it in 4x4 it raises and lowers the rpm as i drive. take out of 4x4 and no problems. why?

What a difference an inch makes. Different sizes make the ratio wrong to run it in 4wheel is my 2 cents worth.

I ran 31 on the front and 32 on the back ,ONCE!!!!!
It was unbelievably squirrelly in the snow,1 inch throws the ratios way off

i never thought 1 inch would throw it of that much. it makes the fronts spin or the rpm goes up like its supercharged
