Does changing to 17" wheels also affect speedometer?
Just curious, I know when I have changed tire sizes before, I also changed the gearing for the speedo. Any insight would be appreciated.

not as long as you "plus one" the tire size. In other words, you compensate for the larger diameter wheel with lower profile tires to maintain overall diameter.

The stock wheel and tire is a 215/55-16. This is almost exactly the same diameter and rolling radius as a 235/45-17. Thus, if you use this size 17", you will see no effect on your speedometer, odometer, etc.<p>Ira

215/55-16 vs. 235/45-17
Jack, I think 1.0% is equal to 1 mph. 0.01% is negligable. The S4 wheel is 17 x 7.5 and comes with 225 section tire. Does it handle 235 section OK? anybody fitted this and have experience?
