Mix and Matching Tires

[GreatDaneHummer]

Wanted to know how much of a difference in diameter can two sets of tires be before having issues? For example:

Running Interco Super Swamper Boggers in rear at 36.8x13.5x17 tires with Pitbull Rocker 36.5x13.6x17 tires in the front. Would the .3 difference really make much of a difference or would it provide some messed up friction due to rotation?

Thanks!

Prolly okay in 4HI-Street mode. I would not do that in either locked mode on dry pavement.

Add a couple of PSI to the front it make the tires close to the same. But not something I would leave, temporary fix only.

Other then a mismatched spare, the question is why?
