Sidewall

Standards that measure treadwear, temperature resistance and traction, example: "640 A A".  The 640 is the treadwear test and it lasted 6.4 times longer than the comparison tire tested against.  The first "A" is the traction rating using straight-line wet traction on test surfaces (see information tables tab) and the second "A" is the temperature rating by testing operation at high speeds without heat-related failure (see information tables tab).

UTQG

Wet Traction is a piece of the UTQG for example if  UTQG is: 500 AA A, the wet traction piece is the second piece, the "AA".

Wet Traction

Measured in 32nds of an inch, this metric shows how much tread life is left on a tire, with the tire's traction & stopping capabilities greatly diminished at 4/32nds and less. Tire manufacturers include "tire wear bars" at 2/32nds to indicate when your tire is worn out.

Tread Depth

The highest inflation pressure (measured in pounds of force per square inch, PSI) the tire is designed to contain, and should only be used when called for by the vehicle placard.

Inflation Pressure

An identifier of a particular tire line and size combination assigned by the tire manufacturer.

Part Number

Tread Design

The Potenza Sport is noted for its outstanding balance of traction and handling, scoring 9.9 on both parameters. Developed for summer conditions, this Bridgestone tire is made from a special ultra-high silica compound to enhance grip and handling on dry and wet roads.

While the 3D sipes in the Potenza Sport boost grip and ensure consistent performance even as the tire ages, the tuned tread design makes your ride quiet and comfortable by minimizing road noises and vibrations. With a softer tread compound, the UHP tires do not last long like an all-season tire. With a durability score of 7.3, the Potenza Sport is placed well for a high-performance tire.

These tires are designed with large grooves and dense sipes to enhance handling, traction, and grip on treacherous terrains. You can go for the [Nokian Hakkapeliitta R3](https://simpletire.com/brands/nokian-tires/hakkapeliitta-r3#v=1&tireSize=255-45r18&mpn=t430728), the best 255/45R18 winter tire sporting an overall SimpleScore of 9. The Three Peak Mountain Snowflake symbol assures its outstanding ability to perform in severe snow and ice conditions. With a directional tread pattern and deep lateral grooves, it offers excellent traction to keep you gliding through freezing terrains. The traction score of 9.9 out of 10 is a testament to its abilities in sub-freezing temperatures. The deep grooves and special tread compound boost its handling as the tire is engineered to remain flexible at lower temperatures for enhanced grip on slippery surfaces, evident from its score of 8.9.

## 5. Pirelli P Zero (PZ4-Sport) - Best Summer tire

If you frequently venture out in warmer weather conditions for high-speed rides, you should go with [summer tires](https://simpletire.com/categories/summer-tires) to excel both in dry and wet conditions as they deliver consistent traction and performance, offering responsive handling and superior control.

The P Zero (PZ4-Sport) offers excellent traction, evident from its fantastic traction score of 9.6 out of 10. While it features an asymmetric tread pattern with sipes and grooves enhancing safety, the circumferential grooves help in the quick clearing of water from the tread for superior wet performance. The optimized shoulder on the outer tread area boosts lateral stability, handling, and grip, justified by its excellent traction score of 9.4 with an excellent steering response. The reinforced steel belt construction enhances handling, while its optimized ribs help in confident cornering. The special tread compound minimizes rolling resistance for increased fuel efficiency. Built with a softer compound with a special focus on grip and traction, the durability is slightly compromised as its durability score is 7.4. However, most summer tires have shorter life spans due to their fast-wearing tread.
