Just picked up a 2003 LT. It only has 8,000 miles on it. The rear tire is worn & cupped more on the left side than the right. I plan on on putting new tires and final drive bearing just to put my mind at ease. I found a set of Metzler 880 tires in sizes 120/70VR-17 and 160/VR-17. After searching this site I understand these tires are made in bias and radial forms. The ones I priced are radials. Any thoughts or concerns with using these tires??
