Read winter-tire markings as separate clues, not one overall score. The three-peak mountain snowflake (3PMSF) means a tire met a defined severe-snow threshold. An EU ice-grip pictogram, where present, addresses ice braking separately. Wet-grip labels and U.S. UTQG grades describe controlled wet-pavement braking, not snow or ice. Start by confirming the tire size and vehicle specification, then match the evidence to the roads you actually drive.
What each winter-tire mark actually tells you
A sidewall symbol or label answers a narrowly defined question. Treating any one mark as a complete winter rating leads to poor choices, especially when a route mixes deep snow, polished ice, cold rain and bare pavement.

| Mark or rating | What it measures or certifies | What it does not establish |
|---|---|---|
| 3PMSF / Alpine symbol | Approval for severe-snow use under the applicable regulatory test procedure. | A ranking among all snow tires, ice performance, wet braking, cornering or hydroplaning resistance. |
| EU ice-grip pictogram | For eligible C1 passenger-car tires, compliance with the applicable ice-braking requirement; the European Commission cites ISO 19447 for the test. | That every winter tire has passed an ice test, or that the tire is superior on every winter surface. |
| EU wet-grip class | Relative wet-surface braking performance within the European tyre-label system. | A U.S. UTQG grade, a complete rain-handling score, or snow and ice ability. |
| U.S. UTQG traction | AA, A, B or C grade for straight-ahead stopping on wet pavement under controlled conditions. | Snow or ice traction, acceleration, cornering, hydroplaning resistance or peak traction. |
| U.S. UTQG treadwear | A comparative wear-rate grade. | Winter grip, stopping distance or a guaranteed mileage figure. |
| U.S. UTQG temperature | Resistance to heat and ability to dissipate heat, graded A, B or C. | Snow, ice or rain performance. |
The European Commission explains the separate snow and ice symbols in its tyre-label guidance and its explanation of tyre properties. U.S. definitions come from the National Highway Traffic Safety Administration (NHTSA) Consumer Guide to Uniform Tire Quality Grading.
Snow: identify the 3PMSF (Alpine) symbol
What the symbol looks like
Look for a mountain outline containing a snowflake on the sidewall. It is commonly called the Three-Peak Mountain Snowflake, 3PMSF, or Alpine symbol. It is different from a marketing phrase such as “winter compound” or a manufacturer’s snow logo.
#1 Best Overall
- Hankook Winter i Pike RS2 W429 is a Premium Touring studded winter tyre with directional tread pattern, designed for Passenger cars.
- Three Peak Mountain Snowflake certified
- Can be pinned with TSMI #11 studs, where permitted, for extra traction in severe ice and snow
- Wide block in the center of the tread provides improved snow and ice traction
- Built with a new rubber compound that boosts strength and durability for a longer tread life
What approval means
The mark indicates that the tire passed the severe-snow grip test required by the applicable framework. UN Regulation No. 117 describes the special snow-grip test used for regulated severe-snow tires. In practical terms, the tire has demonstrated a minimum level of performance in a defined snow test.
What approval does not mean
- It does not rank one 3PMSF tire above another.
- It does not certify braking or cornering on ice.
- It does not predict wet-pavement braking or resistance to hydroplaning.
- It does not account for every temperature, snow texture, vehicle, load or road surface.
Use 3PMSF as a threshold filter: if severe snow is a regular possibility, it is meaningful evidence that an all-season tire without the mark may not provide. Once candidates all carry it, compare condition-specific tests, construction, size and vehicle fitment rather than assuming the symbol identifies a “best” winter tire.
Ice: look for separate evidence
The EU ice-grip pictogram
On the European label, an ice-grip pictogram is separate from the snowflake-in-mountain symbol. The Commission says the ice pictogram is available only for eligible C1 passenger-car tires that meet the required ice-braking threshold, with ISO 19447 cited for the ice test. A winter tire can therefore carry 3PMSF without displaying an EU ice mark.
How to use it
If your route includes frozen intersections, glare ice, packed snow that has polished into ice, or frequent temperatures around freezing, seek an explicit ice mark or a comparable ice-braking test. Do not infer ice capability from 3PMSF alone. Check that the test or label applies to the same tire model and size you intend to buy; a result for one size is not automatically a result for every size.

Why ice is harder to generalize
Ice grip changes sharply with temperature, surface texture, water film, tire pressure, vehicle load and the presence of studs or other tread features. A threshold pictogram is useful evidence for its defined test, but it cannot describe every icy road. Drivers who encounter ice only occasionally may reasonably prioritize balanced wet and dry behavior; drivers who routinely travel on ice should give ice-specific evidence more weight.
Wet roads: understand which labeling system you are reading
European wet-grip classes
European tyre labels assign a wet-grip class from a standardized wet-surface braking test. The class lets you compare tires within that label system. It is not a combined score for steering response, cornering, aquaplaning or cold-weather grip. The European Commission’s tyre-labelling questions and answers describe the label framework and its categories.
U.S. UTQG traction grades
In the United States, UTQG traction grades are AA, A, B and C. NHTSA’s guide states: “The traction grades, from highest to lowest, are: AA, A, B, and C.” The test concerns straight-ahead stopping on wet pavement under controlled conditions. It does not test snow or ice and does not cover acceleration, cornering, hydroplaning or peak traction.

Do not translate an EU wet-grip class into a UTQG letter. They use different labeling rules, test procedures and comparison populations. A high result in either system is useful for the wet-braking question that system addresses, but neither is a complete rain-handling or winter score.

Why “wet” and “winter” can pull in different directions
A soft cold-weather compound can improve cold-surface grip while producing different wear, steering feel or warm-weather wet behavior than a touring all-season design. Compare tires tested in the same size and under similar conditions, and consider the temperatures and precipitation you actually see rather than choosing by a single letter or class.
UTQG treadwear and temperature are not winter ratings
Treadwear
UTQG treadwear is a comparative wear-rate grade, not a guaranteed service life. A larger number indicates a lower observed wear rate relative to the reference used in the UTQG system; it does not tell you how a tire brakes on snow or ice. Driving style, alignment, inflation, load, climate and road surface can dominate actual wear.
Temperature
The temperature grade indicates a tire’s resistance to heat generation and its ability to dissipate heat. It is relevant to sustained high-speed heat management, not to winter grip. NHTSA’s consumer guide also explains that winter-type snow tires are excluded from the UTQG marking requirements described there, so the absence of a UTQG marking on a winter tire is not evidence that the tire lacks a winter certification.
What NHTSA’s current-page figures do—and do not—show
NHTSA’s TireWise page displays the following distribution of current tires; the figures were accessed in 2026 and are not presented there as a dated study or as a measure of winter quality:
Rank #4

- Driving Conditions: Studless Winter Traction
- Styling and Construction: One Black Sidewall, Radial Construction, 16 Inch Tire
- Load Index and Speed Rating: Load Index 91 Supports up to 1356 lbs Per Tire and Speed Rating H Certified to 130 mph
- Additional Note: Tire Only - Rim/Wheel Not Included
- Treadwear: 15% are below 200; 25% are 201–300; 32% are 301–400; 20% are 401–500; 6% are 501–600; and 2% are above 600.
- Traction: 15% are AA, 77% are A, 7% are B, and only four tire lines are C.
- Temperature: 62% are A, 34% are B and 4% are C.
Those percentages describe how the ratings are distributed on that page, not how tires perform on snow, ice or a particular vehicle. The definitions and limitations are in NHTSA’s Tire Safety Ratings and Awareness material.
A step-by-step method for reading a candidate tire
- Confirm the vehicle specification first. Read the owner’s manual and the driver-side tire-and-loading information label. Record the complete size, load index and speed rating; do not substitute a tire solely because its diameter appears similar.
- Check the market’s labeling system. A tire sold in Europe may show the EU label, while a U.S. tire may show UTQG markings. Record which system produced each number.
- Find the severe-snow mark. Look for the 3PMSF mountain-and-snowflake symbol when deep or severe snow is expected. Treat it as approval to a threshold, not as a ranking.
- Look for ice-specific evidence. On an EU label, check for the separate ice pictogram. If it is absent, do not assume the tire failed; it may simply not be an eligible C1 tire or may not carry that marking. Seek a comparable ice test when ice is a major concern.
- Record wet performance in its own system. Write down the EU wet-grip class or U.S. UTQG traction grade without converting one into the other.
- Use treadwear and temperature for their limited purposes. Treadwear helps frame comparative wear and temperature addresses heat resistance. Neither should decide snow or ice suitability.
- Check test comparability. Prefer results for the same model, size, load and speed specification, tested on similar surfaces and at similar temperatures. A result from a different size or vehicle can change the conclusion.
- Match the evidence to your route. Decide whether deep snow, packed snow, ice, cold rain or frequent wet pavement is the dominant risk, then give the corresponding evidence the greatest weight.
How to compare tires for different winter conditions
| Your main exposure | Evidence to prioritize | Questions to ask |
|---|---|---|
| Deep or frequently unplowed snow | 3PMSF approval, snow-test results in the correct size, and a vehicle-appropriate winter category. | Was the test performed on snow comparable to your route? Is the tire correctly sized and load-rated? |
| Packed snow and recurring ice | 3PMSF plus an EU ice pictogram or comparable ice-braking evidence. | Does the ice evidence apply to this model and size? At what temperature and surface condition was it measured? |
| Cold rain and mostly bare pavement | EU wet-grip class or comparable wet-braking results, along with cold-weather suitability. | Are you comparing the same label system and similar test conditions? How much snow will the tire still encounter? |
| Mixed snow, ice and rain | A 3PMSF tire, any available ice-specific evidence, wet performance in a consistent system and independent tests covering more than one surface. | Which compromise matters most for your route, and are the tests directly comparable? |
No official source listed here establishes one universally best tire for mixed snow, ice and wet-road driving. The sensible choice is a fitment-correct tire whose evidence matches the surfaces you actually encounter.
Fitment, pressure and vehicle requirements
Use the owner’s manual and vehicle label
NHTSA advises checking the owner’s manual or the vehicle tire-and-loading information label for the recommended tire size. That label also helps identify the correct cold-inflation pressure. A 3PMSF symbol cannot compensate for an incorrect load index, speed rating, rim size or pressure.
Compare like with like
Keep model, size, construction, load index and speed rating as consistent as possible when comparing test results. Different sizes can use different tread designs or compounds and can produce different braking distances. If you change tire size, verify wheel clearance, manufacturer approval and the vehicle’s pressure-monitoring requirements.
Remember that winter tires are a system
NHTSA says winter tires are more effective than all-season tires in deep snow. That statement concerns tire category and conditions; it does not rank individual models. Correct pressure, adequate tread, balanced installation and a vehicle suited to the tire remain essential. A rating is evidence about a tire, not a substitute for safe speed and following distance.
Common rating mistakes and the correction
- “3PMSF means the best winter tire.” Correction: it means the tire met a severe-snow approval threshold.
- “The snowflake proves ice grip.” Correction: the EU ice pictogram and ice tests are separate evidence.
- “UTQG AA means excellent winter traction.” Correction: UTQG traction is controlled, straight-ahead wet-pavement stopping.
- “A high treadwear number means a tire will last that many miles.” Correction: it is comparative wear, not a mileage warranty.
- “A temperature A grade means the tire handles snow.” Correction: temperature concerns heat resistance.
- “EU wet class and U.S. traction letter can be placed on one scale.” Correction: they belong to different systems and should be compared only within their own frameworks.
- “Any winter tire fits if the diameter is close.” Correction: verify complete size, load, speed and vehicle requirements first.
- “A label replaces a road-specific test.” Correction: labels are standardized evidence for defined conditions; use comparable independent tests for the surfaces that matter to you.
A practical buying checklist
- Write down the exact size, load index, speed rating and pressure from the vehicle documentation.
- Choose 3PMSF when severe snow is part of the expected trip.
- Seek the EU ice pictogram or other ice-specific results if regular ice is a concern.
- Compare wet-grip classes only with other EU-labeled tires, and UTQG traction letters only with other UTQG-rated tires.
- Do not use treadwear or temperature as snow or ice scores.
- Check that test results match the intended size, vehicle and conditions.
- Confirm current market requirements and the tire’s availability before purchase; labeling rules and product specifications can change.
