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

My new Bridgestone Driveguard Plus tires give me better handling, better traction, a better warranty, and a quieter ride that the original equipment Pirelli tires, at a much better price. I would definitely recommend Bridgestone Driveguard Plus tires for anyone shopping for tires.

The tire sales person talked me into getting the DriveGuard Plus since the cost was only about $25 more than the other Bridgestone tires he offered without the drive flat capability. The ride from the new tires is not as smooth as with the old Bridgestone tires (Ecopia) I was used to. I realize the tire design is such that the drive flat capability requires the sidewalls to be stiffer. That results in the irregularities in the road surfaces to create a bumpier ride. If I ever need to drive on a flat tire it will be worth it to have lost the smoother ride. It is not clear what the impact of the rougher ride will be on the suspension, shocks and struts, but now I am worried about that. Time will tell!

Trying the new drive guard plus tires after two previous sets of driveguards. So far the plus tires seem to have a bit more precision in regards to handling twisty dry roads. Only one drive in rain and they performed well at highway speed. Only gripe so far is they are a bit rougher over expansion joints than the original driveguards. Am curious how they manage in a Northern Minnesota winter.

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.
