I am 100% positive 285/30/18 and 275/35/18 will fit the 18x8 front rim. Your tire installer may not be happy, but it is easily doable.

The bigger question, is whether that setup will clear the front fender. That depends on the offset and camber of your setup.

If my 275/35/18 Hankook's Z214s don't sell, then I'll mount them on my stock 18x8 rims, give it a try to see if it clears the fender, and report back. I'm not enthusiastic about this since the ideal size would be 275/30/18 instead of 275/35/18.

I'm 99% positive that 255/35/18 would clear the front fender on stock 18x8 rims, stock offset, with a camber of -1.

 

Thanks Balefire, Ill give it a shot. My fenders are flared so maybe it will work. Thanks again and take care!
