These tires are decent, drove them over the Sierras during the winter and they did fine. They just don't last very long, had to replace before 17k miles. It's a bummer because I really wanted to like them but won't be getting them again. No milage warranty either.

Purchased these tires because of all the positive accolades but this is what I found out after two weeks: The ride comfort and noise were just okay compared to the OEM tires on my Volvo. The mpg was reduced by 3.2 mpg over the OEM tires. However, the worse thing is that these tires tramline terrible on grooved concrete which is unavoidable in my area. I have driven over 60 years now and never saw/felt something this bad = even my mud/snow tires on my truck do not do this. I returned the vehicle to the local Firestone dealer and the manager drove the vehicle to see. His comment was "terrible tires". Anyway, I hate returning anything but these tires are so scary to drive on that I had to. Thank goodness that the dealer totally agreed and returned all my money. Firestone needs to do a lot better and warn people about this or there will be accidents due to these tires.

Purchased set of 4 tires, ALENZA ULTRA 225/65R17, last summer. They are the LOUDEST tires I have ever had the misfortune of buying. Will never buy again. Low rating is for noise, cannot carry on a normal conversation with front seat passenger and forget about conversing with back seat passengers without yelling.

I bought a new set of Bridgestone Alenza Ultra, this was my third set that I have bought on different cars that I own and this third set by far is the worst set that I have bought. I only have driven the car for around 30,000 miles and the tires have worn out evenly. I had the car aligned and made sure on my part the tires would last but they did not.

I replaced the original Continental tires on my Edge ST with the Bridgestone Alenza AS Ultras. The Continentals lasted 25,000mi. The Bridgestones were just shy of the wear bars after about 22,000mi. and had to be replaced before winter. They were rotated and all 4 tires had about the same tread life remaining and were worn evenly across the tire. The car was not driven aggressively. They are a low profile tire, size 265/40R21, maybe around 23,000mi-25,000mi is all i can get out of that size. I just hoped for a little longer tread life. Still, the tire had a nice tread design and seemed to handle great in snow last year and on wet roads even at 3/32 tread depth. The ride was smooth and quiet and they came at a reasonable price compared to other similar tires. I ended up replacing them with another set of the same Bridgestone Alenza AS Ultras mainly because of the price. They're a good, top of the line, tire brand and they were priced well below Continental, Pirelli, and Michelin, and had a nicer All Season tread design than their competitors. I would recommend this tire.

Purchased the Bridgestone Alenza AS Ultra for my wife's Mercedes GLS with the expectation of having a comfortable, quiet tire with long treadwear as Bridgestone advertises and I've experienced with Michelin tires. Within 17,000 in 1 year of use, the Alenza's are at 3/32 and closing in on the wear bars. I didn't feel safe having my wife and son continue to drive the vehicle with these tires after only 17,000 miles due to the potential to aqua-plane due to the worn tread. As such, I was forced to buy new tires. I wouldn't recommend this tire if you are thinking that Bridgestone's claimed 800 treadwear rating has any validity to it unless my 4 tires were defective. I'm sure I'm not the first consumer to bring this matter to Bridgestone's attention. These tires do not perform as advertised.

I've been around the block with OEM tires on my 2014 Porsche Cayenne S as well as a 2013 Mercedes GLK 350 and sorry to Pirelli and Michelin but nothing compares to the immediate satisfaction of a smooth quiet ride of the new Alenza AS Ultra and with an 80K mileage warranty, I'll be reporting back for a long time. I had the Bridgestone Dueler H/L on a Mercedes ML350 and they were great as well regarding wear and ride. Make no mistake, the Pirelli and Michelin brands make fantastic tires but neither never made it to half the mileage warranty even with consistent rotation. I did receive a prorated cost due to early tire wear but it gets expensive replacing tires like these every 12 - 18 months.

Just replaced original Bridgestone Alenza on my Highlander. Hoping I get more than 32k miles with new Alenza AS Ultra. No problems with ride or comfort but disappointed with mileage on originals. I'm trusting Bridgestone to deliver with the AS Ultra.

I replaced the OEM Continental tires with the Bridgestone Alenza AS Ultra because this was Tire Rack's highest rated Bridgestone in my size, although it was not their top tire, and I already had Firestone's Lifetime Alignment on this vehicle. They matched Costco's installed price, also. One of the Continental tires had a belt break, and winter was just around the corner and tread was thin, so I replaced all four tires just before a 600-mile road trip from SC to VA. I've had Bridgestones before, and was never disappointed when I bought a highly rated tire. The first thing I noticed was the effortless steering, like the front tires were on ice. I don't know if that's good or bad. On the Interstate, the tires soaked up minor bumps like they weren't there --- the bumps didn't make it into the car, which the passengers appreciated. Is this because of fresh rubber or a tire characteristic --- time will tell? Concrete pavement separators, bridge entries and exits, and pavement repair bumps disappeared as-if I had new shocks. And road noise from tires vanished. We have lots of stretches of some very noisy pavement, but you wouldn't know it with these tires. Again, is it the tire or simply fresh rubber? As the driver, I really appreciated this. I have TPM and the pressure never wavered. I drive on curvy roads, faster than I care to admit, but these tires didn't squeal or slip. We have not had winter yet, so I can't report on that, but if the tire performance so far is any indication, I've got a real winner of a tire.

This tire is on a 2020 Jeep Grand Cherokee. The vehicle is driven by my wife and our residence is in a mountain area that can receive a great deal of snow, The tires were recently installed and my wife was very pleased with the traction and comfort of the new tires. The Alenza AS Ultra replaced an OEM set of Bridgestone on the Jeep. This new Alenza tire is a big improvement over the previous Bridgestone tire.
