stock size with 16's is 245/75/16 i believe

 

Stock is 235/70r16. 245/75r16 is the largest you can run without a lift.

 

ok, so now i check discount tire and they say its 255/65/16.

 

Sorry, had a brain fart and forgot we were talking about a D2. 255-65 is probably right.

 

ok, well i was wrong then, not the tire size. so how are the speedo's set up on these? is there a sensor thats gone bad? cable stretched??

 

if the truck only has 18,000 miles they better be original. is your speed reading right? go on the highway and have your wife drive the same speed as you, she is shes going faster.

 

Ok so the trucks mile counter is good. Im just the broken part of the equation. The truck actually had 17,700mi when we bought it. I was going off of what she had said was on the truck. I drove in my other car a certain distance and repeated the route in my truck to make sure. Sorry about the scare. But thanks everyone
