I was looking at Pirelli P7000 Super Sport All-Season at Tire Rack. What sizes would work so that it doesn't change the tire size, the wider the better.

Here are the sizes:
225/45ZR17
235/40ZR17
235/45WR17
245/45WR17
255/40WR17
265/40ZR17
275/40WR17

I believe the stock size is 225/55 17 and the rim is 8". How big can I put and which one has the smallest error?<ul><li><a href="http://www.tirerack.com/tires/pirelli/pi_p7000.htm">http://www.tirerack.com/tires/pirelli/pi_p7000.htm</a</li></ul>

What sizes use the same size as the 17" oem ones. Any site to calculate this..

being Very noisy. There are a few on here with Dunlop SP9000s. I think Bart Lane has SP9000s, don't you Bart? A very nice performing tire and quiet too.

Not sure what you mean by which one would not change the tire size. If you mean would have the same circumference as a 225/55/17, I am not sure if there is a formula for that. There may be. Anyone know? In any event it is my understanding that a tire that is wider than the rim may be going in the wrong direction. It is my understanding that it is better for the tire width to be slightly smaller than the rim. I believe the idea is that the tire will roll over less in heavy cornering under this set up. Also you get more bite out of the side tread in this situation. Another thing to consider is the bigger the patch the more water you need to dispalce to prevent hydroplaning.
I am driving on the Michelin Pilot XGT which is available in an exact size match for the stock 17" tire. I have mine on the Ronal 17" R-28 which is slightly wider than the stock rim. I have been through one winter and plenty of rain with no complaints. And certinly no complaints about the way they run dry. I think if I wanted more traction I would need to go to an 18" rim.
Hope this helps.

Hi Charles,

I've read your posts here. Interesting. What happened to the S8? All you are talking about is an A8. Did you sell the S8? I'll do the a dejanews search (Charles A. Ambrosecchia), but I know you had one...you said so. I'll look.

BTW, I was looking over some of your past posts in alt.autos.corvette and Steve's, and am still impressed at your F1 driving stints, 200 MPH street rides, and both F-40 & F-50 Ferrari's. Keep up the stellar reporting and keep the stories coming. I always enjoy a good read.

You are quite a guy. You are the same Charles A. Ambrosecchia that posted the above statements, aren't you? If you are...I was wondering if that C5 supercharger you designed was patented or if the Callaway C5 is still around.

See you later......Sparky

Yes. Give this one a try. You can enter the size and it will calculate the rest for you.

Good luck....
