peacewize Posted November 20, 2012 Share Posted November 20, 2012 First question I have is why does my speedometer not start reading until after I get over 15 mph? Reads fine after that and I can slow down below fifteen and it reads fine but if I stop I have to get over 15 for it to start reading again. Second question is about putting larger tires on. Is there a way to recalibrate your Speedo with the new tires? Any help would be appreciated. thanks Quote Link to comment Share on other sites More sharing options...
djellum Posted November 20, 2012 Share Posted November 20, 2012 both are the speedo gear (at least likely on the sketchy speedo). theres a small plastic gear in your transmission that hooks to the speedo with a cable. its probably worn,slipping, or has fluid and oil in it which is messing up your speedo. if you take it to a speedo shop they will calibrate with the larger tires and put a new speedo gear in to make your spedometer accurate. might fix 2 birds. that said you really have to go waaaayyy larger before it really matters. my tires are 3 inches bigger diameter and it puts my speedo maybe 5 miles off at 55.

scoobiedubie Posted November 20, 2012 Share Posted November 20, 2012 If you have to replace a speedometer gear, the vehicle is most likely totalled before you drive into the shop. They will probably want to get paid in full, up front. But a used one at the wrecking yard and replace it yourself. Quote Link to comment Share on other sites More sharing options...
