5th Gen Tire Selection

[LKitchens]

Just some info for those picking out tires. This is 275/60-20's. The truck has the Bilstein level struts not quite max height and a 1" puck lift in back. 275/65-20's would have filled in the wheel wells better, but i got a really good deal on the tires, and i drive 50 miles (hwy) per day to work and back, so mileage was a concern. Per the truck, i went from 18 MPG to 17 MPG average, just going up to the 275/60 from 275/55.

Did you adjust your speedometer to meet the new tire size?
If you did not, it is easily done with AlpaOBD and some time learning the proper procedures. I made the same size change on my truck, the factory tires I did not like how they handled. The hardest part is the final dialing in the appropriate size to get the speedometer accurate. Take notes of the size values and how the accuracy is, you will need this info to make decisions on tire size as you test. It took me a few hours of having my wife drive while I measured speed on several GPS devices to verify accuracy. Cost a date night out with her, win-win.
