I put on 35 in tires recently and now obviously my speedometer is off.
When im going at about 50mph on the speedo, im really going 55. This isnt a big deal, because i know how fast im going, but it would be nice to fix and would be good for anyone else who drives it.
Anyway, does anyone know how to do this? i know you can buy calibrators from chip companies but is that the only route to go?
1. From what I heard dealer can "regear" your spedo/odometer for a fee
2. You can put GPS with speed display on your windshield and recalculate odometer readings for the service.
