N.sane Posted November 7, 2008 Share Posted November 7, 2008 How big of a difference would the handling be between 17x7.5 with 225/45 compared to 17x8 with 245/40? I found someone whos selling 17x7.5 SSR Comps at a pretty good price, though my original plan was to get brand new 17x8 Enkei RPF1s. Should I stick to my original plan or would the narrower wheel still be a good buy? Link to comment Share on other sites More sharing options...
robinlsb Posted November 7, 2008 Share Posted November 7, 2008 It depends on the type of tires and the actual contact patch of the tires and the section width of the tires. I would decide on the tires first, then the rims. Another important factor is the max load spec of the tire. Once the maximum load is exceeded (like in a turn) the tire will deform and you will lose traction. Tire rack posts the max loads recommended by the manufacture. This is not the real maximum load, but it will give you an idea in terms of comparisons of sizes. For example; A 225/45/17 Goodyear F1GSD3 XL has a maximum load spec of 1477 LBs a 245/40/17 Goodyear F1GSD3 (no xl available) has a maximum load spec of 1356 LBs. The 225 will almost certainly outperform the 245 in turns!!! "Belief does not make truth. Evidence makes truth. And belief does not make evidence."

JoeFromPA Posted November 7, 2008 Share Posted November 7, 2008 N.Sane - I'd recommend the 17x8 with 235/40/17 tires on it. You'll get a nice wide contact patch with the same or actually slightly less sidewall height (vs. the 245/40 which would increase the sidewall height slightly). Further, rubbing won't be nearly as much of an issue from what I understand. Joe Link to comment Share on other sites More sharing options...
PhillyWilly Posted November 7, 2008 Share Posted November 7, 2008 235s rub against the inside of the fender unless you roll it. Link to comment Share on other sites More sharing options...
dudeondacouch Posted November 7, 2008 Share Posted November 7, 2008 ^^^ depends on the offset. Link to comment Share on other sites More sharing options...
N.sane Posted November 7, 2008 Author Share Posted November 7, 2008 Thanks for all the input guys. Well, the sale is pending to someone else for the SSR Comps, if that guy doesnt take them I'm next in line. I just realized 17" in anthracite w/ polished lip is discontinued, so I better grab 'em while I have the chance! Link to comment Share on other sites More sharing options...
