Front and Rear Different Size Tires

[prossett]

If I ran different size tires front and back (so same tire on each axle) would the transfer case come under stress or is there some sort of slippage mechanism, like what the spider gears do in the diff, to compensate for the different rates of turn between front axleshaft and rear axleshaft?

I'm thinking of keeping sand tires on the front, but running big-a$$ agricultural tires on the back!

If you have a full-time 4WD transfer case there is a differential in the there like in your axle. You could however do the math and change the gears either in the front or rear axle to compensate. Because you don't want slippage, you want traction.
