What size tire for 18" wheels

I'm thinking about getting another set of wheels, and wanting to know which size tire to get for them. I'm looking at getting a set of 18x8 with either 35 or 38 offset. I'm currently on Eibach Sportlines with 17x7 wheels wrapped in Eagle GTs 215/45R17. Would I need to get a 215/40R18 or 215/35R18? Or should I also a change the tread size smaller or higher than 215? I'm looking to get a decent summer tire for these wheels any recommendations for a good priced summer tire would be really appreciated! I been looking on tire rack at tires, but was wondering if someone with more experience with running 18" wheels would help out.

thanks, alex!

215/40R18 will be closer to your current setup versus the 35 series. http://ejelta.com/tiresize/index.htm...=18&maxdelta=2

Thanks, I just wasn't sure because I seen people run 40 and 35. I been looking at running 40 series since it would be closest to my current set up, but didn't know if some people ran 35 series because of rubbing or for looks.

235/35-18 would fit better and actually might help so that you're not stretching your tires

So if I ran a 215/35or40R18 on a 18x8 wheels the tires would stretch?

I'm not sure exactly, but it seems a bit wide for a 215 from what I've seen. I'll let someone else answer that for certain, I don't wanna misguide you.

If it's a minor stretch it may be ok, because I personally don't like beefy tires, but I have noticed a 235 gives me more options than the 215...

You're not ever going to get stretch on an 18x8, they don't make tires narrow enough to do that.

You don't need to run 215/35/18s unless you're really going low, if you don't plan to do that then 215/40s are fine. Anything larger and you will need to do some fender work and be very specific on what your width and offset are.

Thanks, so with my current set up on eibach Sportlines I should be fine with using 215/40r18 size tires with 18x8 et38?
