an 8" rim can fit 255's, so you might be able to get 265's on the front if you push them... Check the tire specs though, each tire has a different rim size requirement.
on the back tires with the 9.75 rims you could fit some 285's without problems, possibly as big as 295 or even 305 depending on the tire you buy.
That answer your questions?
Funniest post Ive ever seen...
Waitwaitwaitwait! Y'all are complaining the new Mustang has a touch of Aston Martin in the design? That's like saying I like such and such girl but she looks a bit like Emma Watson.
