You may rub your front tires without a leveling kit and/or wheel spacers ?

this is the size of the front tires. the rear has 25x11x12 tires on 12x8 rims. wonder if they will be to skinny for the rear

 

The 10" tires should work on the 12x8 rims. I was told (by a tire guy with experience) that he could make the 7-1/2" wide tires work on my stock rear rims. Now don't get me wrong they'd look awfully weird, but it could happen. None the less, don't take my or his word for it. Go by a local tire shop and talk to them about it. Just find one that has experienced tire guys.
