    About

    The Michelin Pilot Alpin PA4 is part of the Tire test program at Consumer Reports. In our lab tests, Tire models like the Pilot Alpin PA4 are rated on multiple criteria, such as those listed below.

    Dry braking: Dry braking is measure of stopping performance from 60 to 0 mph.

    Wet braking: Wet braking is measure of stopping performance from 60 to 0 mph.

    Handling: For most tires, Handling includes how well the tires perform; in an avoidance maneuver involving a swerve into the left lane and back into the right lane; on CR's wet handling circuit; and steering feel.

    Speed rating Speed rating Speed rating. This letter denotes the maximum sustainable speed and is found directly after the load index. For S-speed-rated tires, it's 112 mph; for T, 118 mph. Speed ratings for other tires include Q, 99 mph; H, 130 mph; and V , 149 mph. Some tires have speed ratings of W, 168 mph and Y, 186 mph. While such speeds may seem wildly impractical, tires with higher speed ratings tend to provide better handling at legal speed limits. Choose tires that have a speed rating at least as high as the one specified on your vehicle's placard or consult your vehicles owner's manual.

    Treadwear warranty Treadwear warranty Commonly used by tire manufacturers to market tires, the warranty describes the typical tread life of the tire. Consumers should view the warranty an indicator of tread life only. Actual mileage will vary with vehicle type, driving style, road, and weather conditions, just to name a few variables. Nearly all treadwear warranties are based on pro-rated amount based on the usable tread worn off the tire.

    UTQG treadwear UTQG treadwear <p>UTQGS, which stands for Uniform Tire Quality Grading System, is a federal government required grading system for passenger tires excluding winter tires. Key information includes Treadwear, Traction, and Temperature appearing on the sidewall of a tire.</p><p>UTQG treadwear, an index developed by the government, compares a tire's tread life with that of a reference tire graded at 100. A tire with a grade of 300 is predicted to last three times as long as one graded at 100. Treadwear grades are just one indicator of tread life, but actual tire life will vary due to a number of factors including road conditions, driving habits, vehicle, and maintenance.</p>
