I drove a new to me truck back from 4 states away yesterday, and noticed the mph listed were different than my fathers who was driving behind me, as well as my GPS stated mph.
Its a 95 3500HD sierra. The wheels are 19.5", and when getting air in the dually tires, I noticed it said "low profile" on it. Ot doesn't llok terribly different in size than the front wheels, excepthe typr of tread
The tires are 225/70r19.5 on the front and back, but only the bak say low profile (they don't look like low profile that are on cars).
Could this make my speedometer say 80mph while im actually driving 71-72mph?
I have won't be able to take it to. Mechanic until next week for a complete look over, so I am trying to diagnose upcoming costs as best I can until then.
