1997 Toyota Land Cruiser Tires Problems

Your Land Cruiser is equipped with Interco TRXUSM/T snow tires (size 265/75/16), and you've experienced tire blowouts while driving on the highway at 62 mph. The rubber has separated from the bead (the edge where the tire meets the wheel) and burst through to the tread, and this has happened multiple times with only about 1,500 miles on the tires. The tire dealer is willing to investigate the damaged tires, but you're concerned about whether they'll be replaced and whether these aftermarket tires are safe to use. Resolving this will likely involve having the tires professionally inspected by the dealer or manufacturer to determine if there's a defect, and possibly replacing them if a manufacturing issue is found.

Your tires experienced two sidewall blowouts within two weeks of each other, both occurring at highway speeds (50+ mph) after only about 19,000-19,500 miles of use. The first blowout happened in December 2000, and a second one followed shortly after on the same vehicle. Fixing this issue would involve replacing the tires and inspecting the wheels and suspension for any damage from the blowouts.

While driving at 45 mph, one of your tires suddenly blew out at 33,000 miles. When you had the tire inspected, the shop found that all four tires were prematurely dry rotted and the rubber was separating from the tire structure. The tires were Michelin LTX 275/70R/16 model. You'll likely need to replace all four tires to ensure safe driving.
