Constancy Ly788

Dealer had put 6 of these on my truck, new, for selling it. Was fine when I got it. Rode nice & was quite. Seemed like nice tires.
I don't drive frequently (not a daily driver). Mostly use for hauling large items from Home Depot, etc., or use it to pull my triple-axle 12,000 lb. boat trailer, or use with our 12' camper.
After driving it for about 2 years it started pulling to the right. Got more & more noticeable. After checking alignment, etc., to no avail I finally gave in and took it to have tires rotated & get checked out. I was shown that the tire belts were starting to fail on the right front tire, distorting the shape & making it pull right. Had to buy 2 Toyos. Tracked straight. Very happy with them.
Then, last week while driving back from Northern Calif. with the camper on, we blew-out the inside tire on the rear. It trashed wiring, the fender struts, wheel-well liner, and bent the fender up. The truck in now in the shop for over $3000 of repairs. The tire had plenty of tread & no cracks or aging. Blew right through the middle of the tread & the steel belts destroyed everything around it. That's 2 out of 6 dead in less than 20,000 miles.
Prior to this blowout, we had been driving on tight, twisty, mountain roads, with drop-offs often over a thousand feet over the edge. Fortunately this blew out on a straight-ish road after down from the mountain. Had it happened just 2 hours earlier, there's very likely I wouldn't be writing this and we'd be a bunch of RV debris in a gorge somewhere.
