Alright I searched this forum through about 400 posts and didn't find what I was looking for...so here goes. I just put 31 X 10.50's on my trooper. The factory size calls for 235/75/15. I was wondering if there is a chart or way of finding out how much this will change my speedo? I'm thinking of pulling over a state trooper to see if he'll clock me so I can find out. That's be kindsa funny, a Trooper pulling over a state trooper. ha ha. But seriously though...if this has been discussed on here before, I appologize but I couldn't find the thread. Anyone...anyone...bueller...bueller??

Find a watch :D. Time how long it takes to travel 1 mile. Take 3600 and divide second it took. 60 seconds is 3600/60= 60 mph. 52 seconds is 3600/52= 69.23 mph. Or just go buy a $100 gps :D
