What's the best size 18" i can go for that will be suited for everyday driving and the occasional track?
I also don't want to go too wide and have the arches scraping,like a happy medium size.I plan on getting some coilovers first.

 

Width and offset of your wheels?

 

No idea,they're the Enkei's the car came out with.235/45/17".Don't know what the offset is.

 

You're on stock Evo wheels? If so, they're 17s, not 18.

What you have to consider is the width of the wheel, not wheel diameter. Tire choices will be limited to budget constrains, and nothing else. E.I. Get the best you can afford! I autox and track myself, and lean toward 17 inch wheels because tires typically cost less. That's something to think about.

 

Yes,check my previous post,17".I would go for easthetical reasons and better handling.I'm thinking 245/35/18".

 

V---- What he said.

 

If you purchase new 18" wheels, the most popular size is 255/35-18.

 

Thank you,the answer i was looking for.
