Tire Affecting Fuel Economy
Posted by liz on August 31, 2006
IF YOU PUT BIGGER TIRES ON A KENWORTH, WILL IT AFFECT YOUR SPEEDOMETER AND MAKE YOUR TRUCK GO FASTER? IS THERE AWAY TO HAVE THE TRUCK CHECKED OUT IF IT DOES AFFECT THE SPEEDOMETER? I NEED PROOF IN WRITTING WOULD I BE ABLE TO GET THAT? THANK YOU
Putting larger diameter tires on any vehicle will affect the speedometer and odometer readings. If you know the revolutions per mile for the original tires and the larger tires, you could calculate the speed differance. If they are already on the vehicle, you can also drive down the highway, set the speed at 60 MPH and measure the time it takes to drive between mile markers. One mile at 60 MPH takes 60 seconds. If it is not 60 seconds between mile markers, the differance is the speedometer error.
