Hi guys. I have to pick up a set of new tires for the summer for my truck and I was thinking of going with a little larger tire my stock tire size on my 99 extended cab 4x4 is 235/70-16 I would like to go a bit larger on the stock rims but I want to keep the speedo pretty accurate a few mph is not a big deal but 5 - 10 mph off is not a good. any thoughts? I was looking on tire rack and I found these http://www.tirerack.com/tires/tires....nSpeedRating=R
These are stock size I was thinking about going up maybe 2 sizes but I am still up in the air on it. anyhelp would be greatly appreciated.

 

If you go to a 265/75/16 it will raise your speedo reading by 10% which is easy to remember.

 

I called the local walmart tire and lube and it turns out I can get the general grabber at2s from that link through them in 255-70-tr16 for 93 bucks a piece which works out well and they have them listed as an optional tire for my truck so it should not mess with my speedo I am guessing it was a dealer option or something. Oddly enough it was cheaper for that size than for the 235-70-16 go figure. thanks for the help.

 

Anytime you go to a taller or shorter tire, your speedometer will be off. Your dealer can reprogram it or you can reprogram it yourself with one of the aftermarket computer tuners (Superchips, Hypertech, etc.). As for tire size, I'd go with a 285/75-16.
