2017 Sienna - 16886 miles. Firestone tires started wearing thin at 16,462 miles. Was told Toyota does not handle that. Called Firestone and was told to go to corporate store. Was told at Firestone store tires were at 5/32 and nothing they could do because tires were not at 4/32. Concerned because family car, tires should not start to wear at less than 17,000 miles. At 16,886 miles while my wife was driving down the city road at 40 mph, 2 Firestone tires blew out. My concern is more tires are on road and there has to be a problem with that batch of tires. Firestone still will not say they are in wrong.

Excessive tire wear on outer edges. Tires were rotated every 5,000 miles or so, after 20,000 tires were very worn. Replaced at 30,000, which was actually way past what was safe for them. Now, with Michelin defenders, an alignment upon installation (which did not show anything), and proper tire pressure at 4500 miles, same wear is happening. Toyota's response was that it is a heavy vehicle. What is it: Tires are falsely labeled for higher milage than they get or are the Sienna tires not the appropriate size for the weight of the vehicle? attached photos: Front wear at 4500 miles as compared to back tire and original tires at 30,000.
