Pirelli Scorpion STR 

Got a set of these for my Tundra Crewmax after the stocks were nearly bald. Significant upgrade from what I had, but I bought my vehicle used, so I can't speak to how the stocks performed new in comparison.

I drive anywhere from 25k-35k miles a year for business, and haul a trailer. I think these tires excel in treadware, response, and wet/dry traction. They are pretty comfortable, but not soft by any means.
My biggest complaint is that they are louder than any A/T tire I've ever owned. Highway speeds up they quite a bit, but have a noticeable high pitch drone around 80 mph. From 0-45 they are ok, but anything after that is a constant drone, and it's pretty disappointing.
I probably wouldn't buy again unless I am in a pinch for cash and these are on sale.
Go get Kuhmos.

Tires are great so far, ive had them before, i am sure they will do fine. so far dry and heavy rain performance was excellent. a word on tire rack, their price was unbeatable, delivered in 2 days, as always tire rack is the only way to buy tires. i do want to mention that i always ship to my house and find an installer independently of tire rack, usually its my car dealer service dept. i have them install and balance the tires and then do a wheel alignment. i can’t comment on the service of having a tire rack certified installer do the job, im sure it depends on installer, Tire Rack is Awesome!!!

I bough a CX9 because it's a SUV that corners like a sports car. I'm from California where it is sunny all the time and moved to Michigan where snow seems to be on the ground 6 months out of 12. This tire kept me on the road and confident (which I'm not in snow).

Our 500 foot driveway gets a ton of lake effect snow. I've never had an issue getting out even with 12+ inches of snow on the drive.

On ice it's not as reliable (certainly would be good for a 2wd on ice) but good enough with AWD to stop and go.

I did a poor job of keeping up with tire rotation. So the front tires wore thin before the rear. Braking and handling did become worrisome with the thin treads. If I had maintained a good rotation they would have lasted another 10k plus (based upon rear tread life remaining).

I just replaced them with the exact same tire. My wife who is an aggressive driver already told me she appreciates the cornering, braking and handling improvements. Plan on getting another 70,000+ miles out of this set which I will be rotating on a regular frequency.

I would say it was a 50/50 split highway/city-back roads. My wife likes the back roads but we take long road trips so overall it balances out.

The drive road native is good with these on ice and snow and whatever nature throws my way.

Basically on the worse mountain road near and on Stratton Mountain, VT from November 1 to January 9, this set of Pirelli Scorpions SRT's served me, my auto and my life, extremely well. My tires are not new. There was 59000 miles on my manual shift 2007, X3 3.0 IS Sports, made in Germany. I felt very safe, even in the middle of a blizzard going down root 30 from Stratton to Brattleboro starting at 5:00 pm.
Occasionally I have felt a slight shift of my wheels on a very wet highway. Going forward at low and high speeds, or backing up on ice, never interfered with how I directed or drove this very safe car. Have had 5 BMW's, 4 Mercedes, 4 Infinitys,Audi, three Saabs, Mustang, GM, Ford and Jeep products.

I average 25K miles per year. As I approach 2 years on these tires (45K miles on them) I have decided to re-purchase them again. I will end up replacing them a little early due to the time of year rather than running them down to the ware bars. Mid January in middle Ga can get a bit slick, and it's not worth pushing them to see how far they will go. They were 3 days old when ATL had a pretty good snow storm, many people slept in their cars stuck on the highways. I had no problem zigzagging around them and got home just fine. I'm sure being new added some, but the tire impressed me with it's ability to get a grip. Heavy rain has never been a problem. Very cold and dry seamed to be the only time the tires lost the feeling of solid contact with the road.

245x50R20 -- Superior tread life; at 81k, will go 100k with very even wear. At 81k, tires remain quiet with perfect balance. Steering is tight and ride very smooth. Dry traction is good as new, but snow and wet traction while good has declined some. Tires have greatly exceeded my expectations. Will probably buy again, but will thoroughly analyze competition when replacing. Firestone Destination LE2 ratings are impressive.

While you see mixed reviews for this tire, I have nothing but glowing words to say about them in the over 12 years I have been buying them. I'm an outside sales rep who drive about 35,000 to 40,000 miles a year....pre & post Covid. On average, I get about 50,000 to 65, 000 per set of tires. I drive about 65% highway and 35% city for my job and these tires wear like iron for me. Being I drive so many miles per year, I'm very cognoscente of their balance and air pressure so I get the maximum mileage I can...especially now that a gallon of regular gas is over $5.00 a gallon. Maybe that's why they last so long for me, even as I drive the wheels off of my Ford Edge every day. They're not the best in every category...but I don't drive in medium to heavy snow or during very heavy rain. They corner great, road noise is tolerable, and they're very reasonably priced.

Nice comfortable tire no road noise just all around great tire

Great match for my vehicle. I use it on a car that I keep in Phoenix, AZ so not a lot of rain and no snow. Very quiet and comfortable. Purchasing & shipping was great and the installer that Tire Rack recommended was also good.

The Pirelli STA looks very well designed with a beefy tread appearance similar to a mud tire design. Surprisingly however, these Pirelli's provide a surprisingly comfortable ride, nice handling and a quiet noise quality. I can understand why these tires are stock on many vehicles as I am very impressed. Having owned brands such as Firestone (Firehalks), Goodyear (GTs) and Michelins in the past, I would say these are similar in quality (imo). I might choose one of the other tires I mentioned if I drove a sporty or luxury vehicle, but with a large, 3 row SUV; dollar for dollar I prefer these over those others.

I bought my 2011 Ford Edge Limited AWD new in December of 2010. My original Pirelli Scorpion STR A's wore perfectly and I just replaced them late June 2015 at 104,000 miles. I replaced at Tire Rack with the identical Pirelli (except STR and not STR A) and hope to get another 100,000+ miles out of these tires too. I rotate on average 12,000 miles (alternate diagonal and left to right). I typically run 38psi and avoid chuckholes and curbs. My alignment must be pretty good....I never checked since it was new. The 104,000 mile tires were in really good shape and I really think I could have gotten another 25,000 miles out of them. When the Edge was new, my goal was to get 50,000 miles out of tires....ended up doubling that, plus 4,000 miles. Also very even wear inside to middle to outside.......and they still were very well balanced....smooth (all original OEM/factory balancing). Two of the 104,000 mile tires had one plug each (which I plugged myself without any problems and always do with my tires).

We just replaced the original Pirelli tires on our 2010 Ford Edge Limited (FWD) today and they had 105,680 miles on them!!! We are very pleased with how many miles we got out of those tires. The miles are mostly highway miles as we live in a rural area. Even still, over 105,000 miles is pretty good! We fully expect to get another 100,000 + miles out of our new set of Pirelli tires!

Original tires on my Expedition, and first experience with Pirelli.....very nice tire. Holds road in all conditions. Excellent wear. I am at 47,000 and still have about 5/16th left with no degredation in handling. I rotate my tires at every oil change (5000 miles). I used to run Bridgestone Dueler AT Revo' s on may last expedition. They gripped even better than these, but did run into lower life of tire, and also more road noise....have Firestone Destinations on wifes car and they seem to grip better (feel) than the Pirelli...more like the Revo's. No shortage of weather extremes here in Chicago. Pirelli STR has done well with all conditions. Might buy them again, but am reviewing all the options out there. Top contenders seem to be Firestone Destination LE, and Bridgestone Dueler AT Revo.
