Rear Fender Flares/Rolling/etc

What he said.

When you say you want an equal increase in the rear, do you mean an extra 30mm width? Or that you want to run a square tire combo? (the same size tires all around)

Because to do a sqaure combo with stock(ish) rears, you'll be able to run up to about a 275, but the front is where you need to add the clearance. The rear, bone stock, can easily house a 255.
