    Does anyone use this combination on a daily driver?

    My wheels are 17"x7.5" with et+40

    I have 215/40 on one set of wheels and it is a pretty spot on fit for a 17"x7" wheel.

    DURR Ryephile's guide is helpful!

    I could possibly throw a 235/40/17 in there too.. most likely would rub though on a R53.

    R888 or A048? Looks like they are pretty close spec wise. 100vs.80 treadwear and I think I read .4 - .5 inch wider

    I like 225 on a 7.5, could go with 225/40.

    FWIW, there's a great size comparison calculator on this page about a quarter of the way down.

    As for the first question.....lots of local folks run the 215/45 on 7" wide wheels with no disadvantages and it actually fills in the gap a bit too.

    I have a pair of Star Spec Z1's currently (215/40/17) and I love them.. a tad bit loud, but nothing to cry about for their performance.

    I was kinda looking to try something different, but for their price (60 bucks less per tire) compared to their competition - it is kind of hard to argue with.

    A question has come about though. On tire rack it states that the 215/40 is wider than the 215/45. Kind of odd and mike make me stick with another set of 215/40's

    Would depend on a car I guess. I run 215/40/17 on 7.5 which barely clear. Doubt 215/45 or 225/40 would fit.

    Well it looks like Dunlops official website info goes against what Tire Rack has listed. That is rather sucky!

    What off-set Goaljnky?

    I know my 215/40 rub on my 7" with 38 offset, (just in the rear.)

    I am tempted to say 42, but would need to check.

    I run 215/45/17 Star specs on a 17x7.5" wheel, R53 lowered with TSW springs. Tires used to rub, especially with a passenger or over bumps, but the fender liner is worn away now so it's fine. Not sure what offset - Kazera KZ-B's. Comfy ride, plenty of grip. I run higher tire pressures at the track to compensate for the extra sidewall, and the car's slower off the line than with smaller tires. I have a set of crappy all seasons that I run when it snows (I live in NC, so once or twice a year) and they're much quicker at 205/40/17.

    BThayer23 - do you happen to have photos?

    I am on the edge of either getting another set of 215/40 or a 215/45 and hoping for a little less noise.

    Somehow I don't have any photos online of the current setup. Guess they're all on my home computer. I'll walk out to the parking lot later today - my boss bought pitchers at lunch, so getting work done isn't exactly a priority today. =)

    If you want less noise, get some Bridgestone RE-11's. Look at the price difference - the extra cash will get you 4% better performance and 40% quieter ride.

    roughly 80 bucks more a tire though! Not worth it IMO. The Z1 is a great tire and not that unliveable

    That's why I'm on my second set. =)

    It's about a half-finger gap in the back and 1.5 fingers in the front.

    I am on 215/40 and have no gap in the rear. Thus no 215/45.

    I like those wheels. What are they? Nice simple design that looks super-easy to clean as well.

    I'm running Kozei TS K1 wheels, 17x7's with Z1 Star specs in 215-45-17. Great combo for autocross. But, I'm thinking of getting a wider tire next. I've read other posts but hoping someone might post their most recent experience. I'm thinking of 225-40-17's or 235-40-17's of some comparable brand to the Z1's. I found a few posts claiming success with both sizes...just wondering if anyone are currently running these. Not really interested in new wheels right now either but I can go to a 7.5" or 8.0" wide wheel late next year. I'm staying in the STX class for autocross.
