After putting on 16500 mi on the Nismo with the OEM Potenza's I noticed the deteriorating tread on the rear 385/40/19 tires. I'm ready for new shoes and am wondering what will be the maximum width increase for both front and rear.

Up front going from a 245 to a 265 shouldn't be a problem, there is a lot of fenderwell up there. My concern is could the rear fenders handle a jump to 305's from a 285? I'm hungry for a more aggressive stance a 305 will give, and the look of the car from behind.

I know the 10" front wheels and the 10.5 inch rear Rays can fit them fine, I'm just wondering if It will be poking out on the sides?

As a rule of thumb when you go up one tire size width it increases the footprint by a half inch. Measuring seems to show it should work, anyone have any experience with this?

Thanks!
