Sidewall puncture experiences
I purchased a new 2012 GMC Sierra HD2500 SLE in June, it came with 20" alloy wheels and Goodyear Wrangler SRA tires (LT265-60R20), load range E.
Within one week, I had a sidewall puncture on one tire while driving on our ranch. The tire had to be replaced. Now, just yesterday, 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 suburbans 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 9250.) I'm thinking it's entirely possible that these Wranglers 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 thought I'd see if any other forum members have experienced sidewall punctures in non-highway driving.
Additionally, over the years I have tried all major brands of tires on our trucks. While the vast bulk of our truck miles are highway miles, we have a mile-long caliche driveway with a steep hill; and it proves a challenge for most truck tires. My experience shows that the Goodrich tires hold up the best in this odd combination. Previous Wranglers, Firestone & Michelins were prone to shedding chunks of the tire once past 20,000 miles.
