I discovered I have the wrong sized tires on my car. When the speedometer reads 60mph, the GPS says 52 mph. To get to 70 mph, I need to peg the speedometer to 80 mph indicated at 3000 rpm. Car has 3:07 TT rear What size radial do I need? Thanks

Bill, Relax. Do the tires look good on your car? Does the car ride nice? No rubbing? Go to a speedometer shop and have your speedo calibrated and forget about it.. You drove it happily until you got that electronic troublemaker, didn't you? Jeff

Bill, I am also running a 3.07 gear in my 4 speed lark. I have
235-60-15's on it . According to this calculator at 3,000 RPM I am running along at 75.91 mph .
look at the brite side, it will reduce your risk of a speeding ticket.
