I put new tires on my Silverado 1500 right before winter started. At about 1000 miles I had them rotated as part of my oil change service.
After that the truck had a slight pull to the ditch. The left front tire pressure would consistently run 1-2PSI higher than the right front, so I know something was causing it to heat up more. As far as I could tell both tires were set to the same cold pressure by my gauges, and the TPMS confirmed.
Usually right after I get the tires rotated the truck drives a little funny for a day or two, then straightens out. This time it never straightened out. It went the whole 6000 miles with an ever so slight pull toward the ditch.
Last week I had my tires rotated again at the next oil change. Truck tracks perfectly now. Both front tires run at the exact same pressure.
Have I got a defective tire? Which one, and how do I prove it?
