Hi Folks, newbie here.
I recently bought a 2002 PreRunner which came with 31" BFG 265/75R/16 tires. Not the tires I wanted so replaced them with 265/70R/16, which is the size my truck originally came with.
LOT smoother ride, but now the speedometer is off. On the highway today, 70 mph on the speedometer was about 66 mph on the GPS.
The speedometer was just about right on as compared to the GPS with the taller tires.
So, what procedure do I use to recalibrate the speedo to match up with the new (original size) tires?
Any help would be appreciated!
