I went for my regular wheel alignment last week and was told my tires need to be replaced — the tread was down to 3/32. I only have 30000 miles on the vehicle. I called Continental and was told the tires are considered a ‘performance’ tire and therefore have no tread warranty. I bought a new set o Michelin Defender tires today. When I look on line, Tire Rack for example says the tires should be good for 65000 miles. I did not expect to have to buy new tires this soon. I am a retired safety engineer civil servant that worked for the Army Tank Automotive Command and also NASA and was involved in several tire recalls in the 1980s for Firestone so I have some knowledge about tires. I rotate the tires every 5-7k and get a wheel alignment at the same time. I do not abuse my tires. I feel that Continental came up with a term so they do not have to stand behind their product. I will never buy their tires. This set came M with my new Sorento
