I posted this on the tire forum and think it my get more use here.

Someone else posted this in another forum and I thought it could be usefull here for some people...........like me. http://www.1010tires.com/tiresizecalculator.asp

 

Interesting. Mostly because as I played with it, it gave me an alert that said if I changed sized more than 3% over stock that I risked brake failure. Hmmmm Not sure that I buy into that. They must sell brake kits?
But thanks. Calculators always come in handy.

 

This is fantastic-


I was looking for something just like this for a car I'm working on.

Thanks!
