Winter Sottozero Serie II Run Flat tires are Pirelli’s second generation of Sottozero Performance Winter / Snow run-flat tires developed for the drivers of premium, high performance vehicles facing challenging wintertime road conditions. Winter Sottozero Serie II Run Flat tires feature Pirelli’s Self-Supporting Run Flat Technology that enhances safety and convenience by providing temporary extended mobility in the event a puncture allows complete loss of air pressure. Pirelli’s Self-Supporting Run Flat Technology allows tires to literally “run flat” for up to 50 miles at 50 mph (80 km at 80 km/h) unless otherwise specified by the vehicle manufacturer for Original Equipment tires.

The Winter Sottozero Serie II Run Flat was developed with the philosophy that winter / snow tires must perform in a variety of unpredictable weather conditions and aren’t just for use in the snowbelt states. Winter Sottozero Serie II Run Flat tires are designed not just as winter / snow tires, but as seasonal tires suitable for the weather and road conditions typically experienced in parts of the U.S. between November and April by providing traction and handling in dry, wet, cold and wintry conditions.

Winter Sottozero Serie II Run Flat tires use a tread compound featuring new polymers and mixing processes that allow them to be ecologically friendlier because they are free of aromatic oils. Pirelli’s Temperature Dynamic Compound technology optimizes the compound for wet and icy surfaces to provide improved traction in winter’s near-freezing and lower temperatures. The tread blocks feature Pirelli’s Interactive Brickwork Siping where the sipes create a brickwork pattern that increases both lateral and longitudinal stability while providing more biting edges to increase snow traction, ride comfort and noise quality. The tire’s internal structure includes twin steel belts reinforced by spirally wrapped polyamide that enhances thermal stability and makes the tires less sensitive to changes in road and air temperatures.

Pirelli’s extended mobility solution is made possible by their MIRS computer-controlled robotized manufacturing system, a production process that assures consistency in the application of the additional sidewall reinforcements that provide the self-supporting run-flat capability.

Winter Sottozero Serie II Run Flat winter / snow tires meet the industry’s severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.

Install Winter Sottozero Serie II Run Flat tires in sets of four only.

Due to the traction capabilities of the Winter Sottozero Serie II Run Flat tires, Pirelli recommends using them only in sets of four to provide the best handling characteristics and tire performance.

Though they cannot be labeled as run-flat tires, tires branded with MOExtended or MOE on their sidewalls offer run-flat-like characteristics by delivering limited temporary extended mobility after a puncture results in complete loss of air pressure. Because MOExtended or MOE tires do not have the same speed and distance endurance of conventional run-flat tires, they should not be substituted in any situation where a conventional run-flat tire is required. To confirm what your vehicle needs, check our Original Equipment tire listing for your year, make and model or see your vehicle owner’s manual.

  1. We just got the first good snow storm. Took my car for a spin. Those tires are pretty good. Car handles the road with 8 inches of snow perfectly. So far happy with those tires

  2. These are quite simply the worst winter tires I have ever used. I drive a MINI Cooper: a lightweight, FWD car that requires good snow tires, and given them, the car does quite well for itself in New England winters. N.B.: these are not good snow tires.For context, my history with snow tires is mostly Bridgestone Blizzak; from my first economy winter tires to their top-of-the-line winters, on FWD and AWD cars. They’re consistently great. I’ve also tried Dunlops (the less said, the better) and Continentals (pretty good).Most recently I wore out a set of Blizzak LM-30’s on my 2009 MINI Clubman S. They were the finest winter tires I’ve used. The dry grip and stability is ridiculously good; in the wet they let go slowly and gave plenty of warning; they never, ever hydroplaned; they pull well over ice and through light snow. Heavy snow was their one less-than-superb area, so I decided to give another brand a chance.Which brings us to the Pirelli Sottozero. With great reviews on TireRack, and a manufacturer rebate, it seemed like a great choice. (Perhaps that rebate should have alerted me that something was amiss.)Pirelli is headquartered in Milan. Per Wikipedia, Milan averages seven days of snow per year, and less precipitation than most of Europe’s cities. In other words, they don’t get cold, or snow, or even cold winter rains like New England does. And the tires show it.In the wet, they lose grip easily and with little warning; at times I would simply find myself sliding (and thank you, BMW, for donating the stability control system to MINI’s cars). In the dry, they respond promptly enough to steering input, but lack cornering grip and brake poorly. In the snow, they’re just embarassing; I’ve had better performance from cheapie all-seasons.Pros: They are round. They are cheap.Cons: Terrible grip in all conditions.Lesson: Do not trust Italians to design for winter. Pirelli, stick to the race track where you excel. Next winter I’ll get Blizzaks again.

  3. These are the best tires I have ever used. We once drove in a ice storm where the entire road was an ice rink. Cars were in the ditch around us and those on the road were swerving horribly. We eased past them with no problems at all. My wife was not a believer of the tires and xdrive until this moment. On another occasion, I got out of an unplowed driveway when 3 cars were stuck next to me. I cruised out of the parking spot with no issue. We get a lot of snow and ice in Ontario, Canada, and these tires held up amazingly.

  4. These tires were aweful. Noisey, poor snow handling vs. Conti Winters and Michelin Ice3. Tread wear unacceptable. Got two seasons on ice3s they’ll be good for another two seasons. Same with contis.

  5. Bought these in the fall for my Mini Countryman All4. I live in New Hampshire and commute over a small mountain and winding back roads and I wanted something that would be great in the snow. In the past I’ve always just used all-season tires, even on AWD vehicles, but after recently moving way out in the sticks and doubling my commute I decided to spring for snows. I’m glad I did.These tires are great. They just love the deep snow. Even in icy conditions, or the light, but very slippery stuff, they’ll let you know it’s slick, but will hold on to the road. I can’t recommend them enough for bad weather conditions.They are a little loud at high speed. They’re a bit harsh at times, especially over pot holes which are everywhere this time of year. Their dry performance is OK, but you can feel the scrubbing on hard cornering. Then again, they’re snows, so I don’t expect Nascar performance.

  6. I purchased a set of wheels and Pirelli snow tires for my 2016 BMW X4 M 40i after the first winter storm that hit the Portland, Or area before Christmas 2016. As I write this review we’re in the middle of the second winter blitz in mid-January 2017. We have received > 13 inches of snow and ice within a 24-hour period which basically has shut the city down.These tires have been a life saver and worth the money. We live in a cul de sac out street has 15 inches on snow and a ¬ľ inch base layer of ice. In addition, we have a lot of elevation in the Portland area. The elevation grade in our neighborhood ranges from 8 to 15%.These tires are money, they cut through the snow and ice with ease. I’ve been able to get our and tackle the side streets and major roads without issue. I’ve yet to spin my wheels on climbs out of the neighborhood or deep snow. Temperatures have been 20 and 31 degrees during the day which is cause a slight melt followed by re-freezing. I can attest that the tires perform well in cold temperatures. I’ve also noticed they offer more stability than I was anticipating on ice and packed snow under normal breaking. I have not experienced any slide, wheel spin or loss of control. Under heavy breaking I do experience a slight bit of wheel slip.I’m now a believer in snow tires I’ll just do the wheel swap in the spring and put the winter set up until next November. Good job Pirelli!
