Newbie Needing Help w/ Wheels & Tires


Recommended Posts

I'm a newbie to the forums so thanks in advance for your help.


Here's the situation - my wife's daily driver is an '08 SpecB. She drives it pretty aggressively, but nothing at the track.


We have two stock 18" wheels that are dented/bent, but the tires still hold air. The dents happened recently and we don't know what we hit. Since two of them are dented we are seriously considering going to 17"s and putting taller rubber on the new wheels to prevent this from happening.


So, a few questions...


1. Should we stick w 18s and buy new wheels that are more durable and won't bend from daily driving?

2. If yes to #1, what brand/model wheel should that be?

3. Should we drop to 17s and put taller rubber on?

4. If yes to #3, what size tire makes up the difference to get back to the original outside diameter of the 18 w rubber on it?


Thanks a ton for your advice!

Awesome wife!


First of all, what is your budget?


OEM wheels are pretty strong, if you want stronger wheel, then you gotta go forged (think $900/wheel) but all wheels do bend, it's more like how you drive


taller tires definitely helps

Stock tire size on a LGT (non-spec B) is 215/45/R17.


edit: Didn't realize the spec. B uses 215/45/R18.


To match that you'll want to use the calculator here:



For 17's I'm getting good agreement with


205/55/17 (narrower tire than stock)

The closest match is 245/45/17, but this may be too wide and cause clearance issues.


I'd say for 17's get whichever has better availability of 215/50/17 or 225/50/17.

I went to 17s for the same reasons. We have roads that endure hot summers and cold winters and they are prone to potholes due to how they are maintained and the temp swings.


I ended up with a forged 17x7.5 (Ray's Volk) wheel and run a 225/45R17 tire that is approx 3% shorter than the factory 215/45R18 on the 18x7 OEM spec.B wheels (also shed around 15lbs a corner). For a closer to stock height, you can run a 235/45R17 but plan on a 7.5 to 8" wide wheel. You could go with the 215/50R17 as well but that's a pretty narrow tire that won't perform as well as a slightly wider tire.


Comfort was increased for me and the extra meat between the wheel and the road gives me peace of mind. My car is lowered slightly so the 235/45R17 was pushing it with my wheel offset, otherwise I'd have gone that route although I did not want to modify my fenders.
