Yeah, I wanted to push the widths on these new wheels a bit. My intent was to run a 255/285 combo, or even a 275/295, but I have small amounts of rub as it is now in certain situations. Once I realized that the 245/275 combo is a sweet spot for tire pricing, I stayed with the widths I'm already running. The only change I made was going to an 8.5" wheel in the front instead of the 8" which will allow me to stretch the rubber onto the wheel a bit, and achieve the same type of sidewall front and rear.
There are a +7 front and +7.5 rear. With my recent brake change I'm going to a +13 on an 8.5" front and a +2 on a 9.5" rear. The front ends up being almost exactly the same front space, but the rears needed to come towards the fender a bit more.
