I have an 07 Screw, stock height, 20" stock wheels. I really don't have a need for a leveling kit. It's time for new tires, the stock Scorps definitely flat spot overnight in the cold weather. Can I fit a 305/55/20 on my stock setup without having any rubbing issues? Also was looking at 33 x 12.5x 20 Coopers. Will these fit, or what size should I be looking at without any issues?

 

......305/55 is a 33x12.50, you might not have any issues if you did it would probly just be trimming a little of the valence. The leveling kit would sure make it look better

 

I agree. You should have no problems, if you have a 4x4. If you have a 4x2, you can fit them with a leveling kit.

 

Thanks guys. What about performance? How much will these affect my acceleration?

 

How much depends on your powertrain and current tire size. The larger you engine and tires and lower your gear ratio, the less the power loss will be.
