Maybe I can put together an Excel spreadsheet that could be posted on MKIV.com. It would allow you to type your wheel diameter, width, offset, and intended use. I would then recommend a tire size in a couple of different $ ranges.
If anyone knows how I can go about getting this posted let me know.
No offense, but the OPTIMAL rear would not be a 285/35. The tire is too tall. 285/30's are the PERFECT rear, since they are the same height as stock equipment, hence, no change in diff ratio or speedo error.
