Your right on with this - I was 5 mph with the stock tires - now with the 37s on on the money. I was always wondering why I was doing 80mph and not passing anyone.....lol.....

5mph helps the warranty to run out faster ----

no wonder I have 80,000 miles on my 2005 already

Tomp - thanks for all your info - it's been very helpful - I am begining to search out for the gears.
