<div class="bbWrapper">I'd rather have the 45 series with a 17" wheel. It will fill out the wheelwell better and have more stock-ish gearing as well. The last thing this car needs is effectively <i>shorter</i> gearing IMO...</div>

They are racing tires so not for street use. 225/45 comes out at 24.7 in diameter so the gearing will be a bit shorter. These are going to be auto-x tires though, so the short gearing will be good for quick acceleration between corners.</div>

<div class="bbWrapper">Well I don't really think about it in terms of 1/4 mile consequences, but in the autocross/road racing arena, I find the stock gearing of this car to be plenty short. My 235/40R18s are even slightly smaller in diameter to the stock setup, and exactly the same OD (mathematically speaking) as a 235/45R17, but are the closest OD that I can get to the stock setup without beginning to exponentially increase the chances of rubbing...<br /> <br /> At any rate, I think for 17" tires, 235/45R17 is what I'd go with.<br /> <br /> I currently only have 17" setup for this car though, and it's a winter setup so maximizing tread width isn't exactly a priority...I'm running 215/50R17 snow tires with that setup.</div>

Nliiitend1 · Jul 23, 2009

<div class="bbWrapper">Honestly I don't see the need for a 9 inch wide wheel. You can't fit much more tire in the wheelwells than you can fit with an 8" wide wheel, plus I don't like screwing with the scrub radius any more than is already achieved by running an 8" wide setup. <br /> <br /> But yes, 235/45R17 is probably the tire size I'd go with if I was putting together a performance-oriented 17" wheel/tire setup. <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f609.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=";)" title="Wink ;)" data-smilie="2"data-shortname=";)" /></div>
