Upgrading your Wheels + Tires?

[Nismo V]

Since I know a lot of people will be changing their wheel and tires packages, I thought this wheel size & speed calculator would be helpful in determing what size you might choose.. Here's the link http://www.net-comber.com/tirecalc.htmlJust plug in the tire spec.. ex. 175-65-15 stock then the size your thinking of say 205-35-18 and then you'll get the calculated actual speed you would be travelling at..

How much does the overall diameter of a tire change due to tread wear? What kind of % off is acceptable?
