I wish I had owned them longer to tell you about durability, but all I can comment on is comfort, handling, and quietness.

I am 70 years old and these are the best tires ever for riding on. I just got back from a 1000 mile round trip vacation on these tires. I was going to buy Michelin from Costco, but when I saw the 45 day satisfaction guarantee Cooper offered at a lesser price and a $70.00 rebate to boot.what the heck I tried them. These are the smoothest and quietest tires I have ever owned. So here is my review of the CS5 Cooper's. I ended up selling those on Craigs list for half price. After replacing one tire, we thought was out of round, we still did not get the ride we wanted. I then put on the second set, Uniroyal Tiger Paws. I spent more time and money on those tires than any I have ever owned trying to get a good ride. The first set was Firestone and we could never get them balanced to be comfortable. My last, and final set, is Cooper CS5 Grand Touring. I have had more trouble than I care to recount with tires on this car. Oh and had them in some stickly clay mud and had no problems driving through a couple inches of that. It's possible some tires get slightly higher fuel economy but I am happy with 31.5 MPG at that speed and load. The MPG on that trip was close to 31.5 MPG on gently rolling hills and utilizing the A/C. (Make sure you don't confuse the Grand and Ultra Touring selections) Here's a performance example: I recall driving on the interstate with my wife, two kids and some gear at 70 MPH.

The Continentals overall were lower grade than the Michelins and Cooper CS5's. The Michelin tires rode very well but did not last beyond 45K miles and were not superior in any way to this Cooper tire for much less expense. The last set were the Michelin Defenders and before that, the factory Continentals. This is the third replacement tire set on this Outback the car has 85K miles. These tires are a pleasure to drive and shine on the interstate roadways. However, after the way they handled this issue with what I believe was a poor product they will never get any of my business again and I certainly will not recommend them to anyone. I have had four sets of cooper tires on various vehicles with this being my first time to experience problems. We had to pay another $477.00 dollars to replace defective tires at half their life. Cooper said they would not honor their warranty as the wear was 'uneven' which is completely false. We had the maintenance records to show that we had followed the companies recommendations to the letter sent with the worn out tires. We asked the dealer if they could be prorated as we were only at roughly 1/2 of the advertised wear life and he said he would check and see. At 42,000 miles on the tires, it was recommended we replace them as the tread was worn down to the wear bars on the front two tires and was at 3/32 on the rear tires. We noticed a loss of traction in wet weather at about 30,000 miles and were told during inspection and rotation that they were wearing very fast. They were kept properly inflated and rotated every 10,000 miles. We had the vehicle aligned at the time the tires were installed. We bought these tires at the recommendation of our local service shop.
