For anyone considering different tires and/or rims, this table might be useful.

Comments welcomed.

Note: It's still strange how the 16 and 17 stock rim/tire combos are 3% different.

Very handy Paul, nice job!
It looks like your chart is set up for the 3-5% rule... you can change diameter +/- 3-5% without overly affecting speedometer reading. This is supposed to account for fluctuations in tire inflation.
I've always found the following link helpful for these comparisons. When I use it, I can get really close to the same overall diameter, but it usually results in tire width being the same a stock I mean, if your going to spend big bucks on wheels an tires, but can't go any wider... what's the point? Who cares what the speedo says anyway, except maybe the cops :eek:

Duhhh, here's the link
