Needed these run flat tires for our Infiniti QX50, and Sam's had the best deal by a couple hundred dollars between the Infiniti dealership and a local tire distributor. The oly issue we had was it took more than a week to have the full set in stock. Once they were in the installation took less than an hour.

It's early in their life cycle, but so far, I'm happy with the performance, noise-levels, and ride of these tires. In direct comparison with the Michelins and Pirellis that we've used before, these have more tread-depth, appearing to have a better life-span. Water evacuation, dry handling, noise-levels, ride compliance all seem to be great.

I think my previous tires were a smoother ride but I haven't had this brand long enough to see if they are as good. Don't drive every day or for long distances. So I gave them 5 stars

Good

I drove on Driveguards previous version (2 sets in fact) and was never truly satisfied. They produced some road noise and never felt smooth/comfortable. The new 'plus' tire is much improved in these 2 features, and seems to maintain all other positives. This might be the best run flat tire out there now - certainly for the price!

This is definitely the longest wear tire I have had. 55000 on the first set now on my second set so far only been 1500 miles but ride and drive like the first set with very easy handling on steering especially in tight corners. It is a run flat tire and since my vehicle comes with no spare I still have confidence when driving on these tires.

A happy day when I replaced my noisy and harsh Driveguards with the Driveguard Plus. Don't get me wrong, the Driveguards were much better than the Pirelli P7 RFs, but the the Driveguard Plus is miles better than the Driveguards. I now enjoy driving on the windy back roads in my town without intrusion of tire noise that I look for any opportunity to run out to the store. Big thanks to the tire engineers at Bridgestone, you made driving fun again!

Old wheel weights were left on all four tires. I took my car to a small independent shop and had tires rebalanced. Did not take back to Sam's because obviously if they knew how to balance the new tires they would have started by taking old weights off first . If I knew this survey was going to happen I would've taken pictures.

tires wore out in 13 months after 15,800 miles. totally unacceptable. need to find out what the warranty is on these. do not purchase.

I purchased four of these tires and they did not make it 10k miles. In just 2 years, two of the tires had a tread rating of 3/32 and the other 2 had a tread rating of 4/32. Hard to be loyal to a tire that has zero durability Upon calling the warranty department, they informed that their tires aren't guaranteed for the 50K mileage that they generously market to consumers. They would only prorate one tire. And they wouldn't even address the wear on the others by standing by their product. What product do you know only last 10% of it's expected life, yet the manufacturer wants you to spend good money over bad to replace them? Buyer beware on both the tire and the manufacturer.
