18" Wheel & Tire Discussion Thread
You will not have to roll fenders. The ideal set up would be 245/40 F and 275/40 R..that's what I have on my 9.5" rims (all around). You will get wheel gaps and harsher ride with all the tires you listed... the worst being 245/35 and 275/30 which will be very harsh and leave huge fender gaps.
I suggest you go here to get comparative tire sizes:

So 245/40 and 275/40 though eh? First time seeing that example. Can you show me a pic? Thanks
Why that comment? We're all not tire experts and I'm asking people for advice, not sny comments towards a legit question.
Unless you're just post whoring.
ANYWAYS, thank-you ronn1. Those fitments look great, what I was looking for. ( I found pics) Been quite the debate over in my house, thankfully I still have 3 months till they have to be on. Gave me quite a bit to think about.

Im looking to get a wider set of tires on my Volks and the rear is a 9.5 inch rim and im running 245/40ZR/18s on them right and i want that more aggressive look. I was told by my wheel and tire guy that i could run 265/40ZR/18 on the back but that was pushing it. Anyone know what the max i could run? Thanks
Your wheel and tire guy doesn't know what he is talking about. According to Tirerack you can run a 285 max on a 9.5 without issue, but you would want to drop down to a 35 aspect ratio so it doesn't look like your driving a 4x4 and to stay closer to your stock diameters. I am currently running 265/35/18's on 9.5's and would go wider if I could, but I'd probably rub.
What are you running on your fronts?
What are you running on your fronts?
My current setup is BF Goddridge G-Force 245/40/18R front, 295/35/18R rear. The tires are mounted on LMGT-4. No cuppling issues with the rear tires for over two years. I wouldn't track my car with that rear setup though. Like someone posted 285 tire is the ideal max for 9.5" rims.

I would probably just run a 275/40 out back, that is standard fitment and looks great. Or you can update your look by buying two new 10.5 inch wide rear wheels and run the 9.5's up front.

Im running 225/40/18 on the front and 245/40/18 on the back, thinking about putting the 245/40s on front and since you guys say 285s on the back will work then i will do that, would it look funny with 245/40s on the front and 285/35s on the back???
Just run a 275/40 , its not like you have extra power where you need the widest tire possible. Also you could also just buy two wheels like i also mentioned and get the proper wheels for 285's. A proper set of 285's really need a 10 or 10.5 inch wheel.
