It's impossible to find pilot super sports right now in a 20 in size for my car. Anyone see anything wrong with running a 235 up front and a 325 rear? Right now I've got a 245 and a 305
Sounds like a wide-body? If four wheel drive, you need to keep your rolling diameters within a few percentage points to avoid impacting the dynamics and stressing the system (at least that what it was like in my 993?). Don't know if those would fit.
Well the size is fine for overall diameter. I was more concerned with that much of a staggered fit Basically the 235 and 325 vs a 245 and 305 setup. The car is a 4s widebody so the width shouldn't be an issue.
The answer depends upon the width of your wheel. The minimum wheel width for a 325 tire is 12". If you have an 11" wheel, you should not exceed a 305 width tire. With our low profile tires, there is even less wiggle room for exceeding recommendations. There are many charts available that show the range that is acceptable, here is one (they pretty much all show the same numbers though):
See I've heard different than that char states. 11.5 is minimum for a 325 according to 1010tires. Discount tire here locally said the 325 would fit on my 11 in wheel
I run 325/25/20 & 235/30/20 on 12"&8.5" on my 2008 c4s and they are a great tire combination on my car. I find the PSS a much nicer tire than the PS2 both on the track and off.
These are from 1010tires.com. The stock tire is the first picture, 325 second, 305 that i'm currently running third. Seems to me like the 325 is a better matched tire to the stock one. It says an 11.5 in rim, and I know stretching a skinny tire to a wide wheel is bad, but would a half an in make that much difference when you go too wide? Plus I've see they fit on 12, 11.5 and 11 in wheels on all different sites.
They make these charts for a reason. If youre not going to observe the sizes they say, then theres no point in looking at them. Just like the local tire knuckleheads, - we can put any size we want on any wheel.
Aside from all that nonsense, if you look at a good car like ferrari, porsche, mercedes, lambo. they have really expensive tires and wheels made for their cars. Look at the sidewalls and the wheels. the sidewalls are nearly even and level with the wheel lip. NOT bulging out. Its not supposed to bulge out over the wheel like a tractor.
So if you dont want everybody to look at your car and say- that guy doesnt know what hes doing- use the right tire and wheel sizes.
That's why i'm trying to verify conflicting information. I'd happily observe the correct sizes, as I'm not some tire stretching jackass as you are so nicely implying. I understand that the sidewall needs to be square, my current tire isn't square on the wheel, it looks stretched actually. I've had a lot of conflicting info on the websites. The discount tire store has a chart and says the 325 fits the 11 in wide wheel. But tirerack online says it won't, then 1010tires says it wont but that tire calculator says it will. Want a squared sidewall here is a 325/30/19 on a 911 wheel that is 11 in wide. Looks very square to me. In fact, it looks more square than my current 305 tire.
