I am having an issue deciding what size wheels and tires to put on my car. I am putting 535 to the rear wheels so I will need a large rear tire, however I was thinking about running 35mm sidewalls. Other than a bumpier/less forgiving ride, what are the negative effects of smaller sidewalls? I would like an aggresive wheel setup and I plan to fully roll all of my fenders and maybe even pull them a little while I'm at it. I know I want an 18" wheel and was hoping to fit some pretty aggressive offsets and just camber my wheels out a little. Any help would be greatly appreciated. Thanks!

 

What size wheels are you trying to use? and how wide to you want your tread width to be? The 35 in the tire size doesn't mean mm, but it means the aspect ratio of the sidewall. It's a percentage of the treadwidth. So, giving your wheel diameter will help a lot in finding the correct tire for your car.

 

I really like the look of 18's much better than 17's. I am not really sure how wide of a tire I want to run yet as I'm not really sure how much tire I'm going to need to handle this much power. Anyone with similar power readings care to offer some advice?

 

Depending on the wheels you can go with a 255/35R18 rear and the 225/40R18 in the front. With a higher offset you could even go with a 265/35R18 on the rear.
If I can help with the tires let me know.

 

Running more camber to fit aggressive wheels seems a bit counter-productive if you're also worried about traction.
