Mine has 16k miles and the tires have a lot of wear. The dealer mentioned excessive wear on my 15k oil change and I started a complaint with Toyo. They recommended my tires be rotated every 2500 miles which seems excessive to me but the dealer agreed to do it at no cost to me. Toyo said they will monitor the situation and may provide warranty assistance. The thing is, our tires have no mileage warranty and the treadwear is quite low (300) so 30k is about right for their longevity. Very poor tire choice IMHO.How many miles did you get out of your Toyos before replacing?
