I purchased a new GMC Sierra HD2500 sle in June, it came with 20" alloy wheels and Goodyear Wrangler sra tires (LT265-60R20), load range E. within 3 days, I had a sidewall puncture on one tire while driving on our ranch. The tire had to be replaced. Now, just yesterday, Sep. 15, I had another sidewall puncture while driving on the ranch. I just left the local discount tire, where they are waiting for a new tire to arrive so they can replace the old tire. I've been living on this ranch for 47 years now, and have owned at least 10 trucks and 2 Suburban over the years. There is a 3.5 mile loop road that runs around the ranch, and I drive it regularly. These two flats are the only two I've ever experienced in driving this loop road, which is a combination of caliche and limestone. The road is not great, but it's not terrible either; and I find it very odd to have two failures within 4 months. (total mileage on the truck is now 9250.) I'm thinking it's entirely possible that these Wrangler have a weaker than normal sidewall; the worker at discount tire told me that my "normal" truck tire, a goodrich dueler at, did in fact have an additional sidewall layer compared to the Goodyear. In any respect, I'm calling this to your attention in case there actually is some manufacturing defect that I should know about. I would appreciate hearing your thoughts on this issue.
