So this is my second set. I put 70000 on the first set and the right rear developed a slow leak. Went to the local Firestone dealer and he said these tires need to be replaced. I said they have plenty of tread. He said after 4 years the side walls have had too much sun and wear. You do not want a blow out at 80 mph. These tires have been driven close to 100 mph across Texas in the summer. They have handled Stevens Pass Washington in snow storms. They have been on soft sand in Hawaii, Washington and Maryland. I'm in the military and move a lot. Logging trails in Washington and Louisiana . Ice storms in Maryland and Washington. I carried chains in the winter in Washington, but never used them. I think the law thought I was 4x4. If I rode on sand often I'd get something else. I tow occasionally, light boats and utility trailers. They are not the quietest or smoothest tires. They do not have aggressive AT tread, but for a great all around SUV tire I think they are an awesome value. I change the oil every 5 k and rotate the tires every 10 k. Check the air about once a month. I hope to put over 250k on the Volvo. If I do I'll be on my third set of Destination ATs. I'm going to put them on my pickup as soon as the ome wear out. The ome on the Volvo didn't last 20 k. I do not own stock in Firestone.
