Yes But...
Yes but my truck is just about out of warranty. I replaced the stock tires as they wore out...went to what are essentially 33" tires with no lift...looks really good this way. I checked my speed with a GPS and I am reading 2mph low...probably not worth worrying about.

My speedo is now about 1 MPH low at 60MPH. Not enough to care about.
Just think how far it was off (on the high side) BEFORE the tires

Yup
I know! Based on GPS and those roadside radar units the DOT puts out, my speedo was about 2 mph higher than actual speed.

For liability reasons, most car makers have 3%-5% error on the high side built in. This is to keep you from suing or claiming liability to the car manufactures for your lead foot and speeding tickets.

yes, mine was this way until I had it fixed. I don't like it being off and not being able to correctly caclulate my mpg.

compared to a lil 4banger no, but I can get 19mpg+ on the highway with 35" tires. Plus I like to know if my mpg starts to drop of significantly as this would be a sign that something is not working properly.
