Three-peak mountain snowflake (3PMSF) tires are not enough for deep snow. They pass an industry snow-traction acceleration test (ASTM F2493) but do not test braking, cornering, ice grip, or rubber flexibility below roughly 7°C / 45°F. For unplowed roads, mountain passes, or fresh snow deeper than about 4 inches, dedicated winter tires (the ones that … Read more
Every winter, drivers walk into our shop asking the same question: do you need four winter tires or just two on the drive wheels? It’s one of the most searched tire questions online, and the answer from every major tire manufacturer is the same. You need four matching winter tires on every wheel position, regardless … Read more
Studded tires are winter tires fitted with tiny metal studs (usually tungsten carbide) embedded in the tread, and yes, they can be worth the trouble on icy roads in one specific scenario: when you regularly drive on untreated, packed-ice roads near the freezing point, like rural routes, mountain passes, or long consistent winter commutes. In … Read more
You should switch to winter tires when temperatures consistently fall below 45°F (7°C), which is the threshold where summer and all-season tire rubber compounds start to harden and lose grip. Most tire makers and our team at American Tire use the same rule: once your area runs a week of mornings below 45°F, it is … Read more
No, all-weather tires and all-season tires are not the same thing. All-season tires are three-season tires designed for spring, summer, and fall, carrying only a basic M+S (Mud and Snow) marking that does not certify winter performance. All-weather tires are true year-round tires that meet the severe-snow standard and carry the Three-Peak Mountain Snowflake (3PMSF) … Read more
Yes, all-season tires work in light snow, but only up to a point. If you live where snowfall totals under two inches and clears within a day, a modern all-season tire will get you through the season safely. Push past those conditions into deeper snow, ice, or sustained temperatures below 20°F, and the same tire … Read more
Yes, it is bad to run winter tires in summer heat. The same soft, high-silica rubber compound that gives winter tires their grip below 7°C becomes too soft once temperatures climb, wearing out up to 60% faster, increasing fuel consumption, and lengthening braking distance by as much as 26% on hot wet pavement. Our team … Read more
If you have a pickup, SUV, or crossover and dread the twice-a-year tire swap, you are not alone. The real question behind “should you buy dedicated snow tires or all-terrains for winter?” is whether one set of snow-rated all-terrain tires can do the job of two sets. The short answer: if your winters bring regular … Read more
If you live in a state that rarely snows, you probably do not need a dedicated set of winter tires. What you do need is the right tire for the cold you actually get, and in most of the Sun Belt that is a 3PMSF-rated all-weather tire, not a true winter compound. The decision hinges … Read more
All-season tires begin to lose grip when temperatures drop below 45°F (7°C). Below that threshold, the rubber compound stiffens and stops conforming to road textures, which means longer stopping distances and reduced traction even on dry pavement — before any snow or ice shows up. I spend a lot of time in the shop talking … Read more
