On an NA 740, I believe stock size is 185/65 R15. I'm not sure what it is on the turbos. But if stock is 185/65R15, then 195/60R15 is slighty smaller than stock. In other words, at 60MPH according to your speedo, you would be going slower by about 0.6 MPH.

For 205/55 R15, you would be going 58.55 even though your speedo read 60.

The closest match is 205/60R15. You would be going 60.53MPH while your speed read 60.

This is assuming your speedo is calibrated to 185/65R15 like mine is though.

try playing with my spreadsheet if you want, it's all based on formulas so just change some values around. http://www.crimetank.com/misc/carstuff.xls
