OK, so I finally got around to ordering some new tires for my little meat wagon... General Grabber AT2's in 295/75QR/16 (oddball size, I know... but I wanted to put the largest tire I could fit safely onto the factory 7.5" wide rim)

Do I just take my truck to the dealership to get them to recalibrate the speedometer? Sorry in advance if this is a dense question [&o]

 

I put 35s on and thought the same thing.
But the school and police dept. have those signs that tell you how fast your going mine is just on target.

 

hmmm....

good to know! thanks dilo!!
