Tire definitions

Over time, normal driving conditions can gradually knock these angles out of balance, resulting in wheel misalignment. Impacts from potholes, curbs, or rough roads, as well as worn suspension parts, can alter the wheel geometry. When that happens, you may start noticing symptoms of bad alignment, such as your car pulling to one side, a crooked steering wheel, or uneven tire wear. In this guide, we’ll explain the main causes and symptoms of wheel misalignment, explore how it affects tire performance and handling, and clarify essential alignment angles.

The tire load index indicates the maximum weight a tire can bear with proper inflation (as recommended by the manufacturer). Tire speed rating indicates the fastest speed the tire can reach before its performance is affected by driving forces (temperature, friction, rolling resistance).

If you drive a car in the U.S., you’ve probably heard the term tire or wheel balancing tossed around at tire shops. Some drivers think it’s optional. Others confuse it with wheel alignment. But proper balancing is one of the simplest services that directly improves tire life, vehicle comfort, and highway safety. Here you have a clear, expert-backed guide to what wheel balancing actually means, why it matters, and when your car needs it.

The tires have many markings and inscriptions on their sidewall. You have noticed them thousands of times and probably wondered what they mean. Well, these markings might be confusing at first. But, with the help of our article, we hope that this subject becomes much clearer for you.

Grand Touring Tires are made for drivers who want comfort on long trips, smooth handling, and reliable performance all year. This tire category bridges the gap between standard touring tires and ultra-high-performance models, offering a rare combination of comfort, durability, and responsive driving. This guide explains what grand touring tires are, how "grand touring" differs in tire classification, how GT tires compare to all-season, touring, and ultra-high-performance alternatives, and when this category makes the most sense for real-world driving.

Ultra-high-performance (UHP) tires are engineered for drivers who demand sharper steering, firmer cornering grip, shorter braking distances, and better high-speed stability than standard all-season or summer tires. UHP tires are not just a label - they represent a combination of advanced compounds, reinforced structures, and precision tread designs. In this guide, we’ll cover what UHP means and how to determine if UHP tires are worth the investment.

Rolling resistance is the amount of energy the tire consumes when it rolls on the road. Higher or lower energy consumption depends on how much the tire deforms while moving and the power the engine exerts while propelling it forward. Factors like tire pressure, size, and tread depth all influence tire rolling resistance and fuel consumption, respectively.

Touring tires are popular among everyday drivers who want comfort, durability, and reliable all-season performance. But are they the right choice for your vehicle? This guide explains what touring tires are, their pros and cons, the different types, and tips for choosing the proper setc

The Three-Peak Mountain Snowflake and M+S tire markings refer to weather conditions in which the tires feel like fish in water. While the UTQG rating explains a tire's traction, temperature, and service life, the Snowflake and M+S markings are about weather versatility.

Ever noticed numbers and letters on your tire’s sidewall, such as 400 A A? That’s your tire’s UTQG rating, a system that measures how long your tires last, how well they grip, and how much heat they can handle. The UTQG rating refers to a system coined by the National Highway Traffic Safety Administration of the U.S. used to grade tires in terms of temperature, traction, and wear. Here’s how to read it, what counts as a “good” rating, and how to use it to find the right tires for your driving style.
