I have had these tires on my truck for about 32K miles. The Dealer told me today that I only have about 4/32 tread remaining on the tires. They were supposed to be good for 60K miles. Now I am digging through all my old maintenance records trying to prove they were rotated every 8K to get prorated warranty out of them. I am missing a receipt and don't know that General will honor their warranty now. Would not recommend tires solely based on tread life. It is only over half of what is advertized in my experince.
