Michelin Pilot HX MXM4

Providing all-season sport handling and a quiet, comfortable ride, this tire is original equipment on vehicles like Cadillac CTS, Acura TL and Mercedes C-Class
  • A European handling profile, featuring a rounder shoulder, is designed to provide progressive, predictable cornering, letting you push your vehicle to the edges of its performance capabilities.
  • 2-D Active sipes which are both variable width and full depth create biting edges to help give you more confidence in rain or snow
  • Comfort Control Technology uses computer optimized design and precision to offer greatly reduced vibrations and road noise

Load Index
Load Range


Safety Rating is a combination of two values: Load Index and Speed Rating for P-Metric and Euro Metric tire sizes; and Load Range and Speed Rating in the case of heavy duty LT (light truck) sizes.

Speed Rating is based on the speed that the tire is designed to be driven at for extended periods of time. All tires in the in the U.S. are designed to maintain legal U.S. speed limits. The speed rating of tires must match the maximum driving speed of the vehicle.

Load Index is used on P metric and Euro Metric sized tires and denotes a tire's load-carrying capacity at a specified inflation pressure. The load index is represented by a number, the higher the Load Index Value the greater the load the tire can safely carry. Vehicle manufacturers recommend a maximum load capacity based on a recommended minimum load index.

Tire Class


Tire Class reflects how the tire will be used. There are four major categories: All-Season, Max Performance, Summer-Only and Winter-Use.

All-Season tires are suitable for year-round driving in all weather conditions.

Summer-Only & Max Performance tires are specifically designed for high-performance driving. Tire compound, tread design and speed ratings all combine to hug the road and maintain grip. Summer tires by nature are not ideal for winter driving due to lack of siding to grip winter roads.

Winter-Use tires have tread compounds and patterns that are specially designed for grip on snowy or icy road surfaces. They are not suitable for year-round use. The rubber compound used will wear more quickly on dry, summer roads. It is recommended that winter tires are fitted as a complete set to avoid potential handling issues.

Tread Type


Tread Type is an important consideration when choosing a tire. There are four main types: Passenger, Highway, All-Terrain and Mud-Terrain.

Passenger denotes a tread that is suitable for normal use, a good all-round tread for normal driving.

Highway is a tread type unique to SUV and truck tires. The tread is optimized for normal everyday driving on paved surfaces. These tires can be driven off pavement, but are not ideally suited for off road traction. Highway tread patterns deliver a quiet ride.

For light trucks and specialty vehicles, All-Terrain tread types provide better off-road traction than standard highway truck tires. There more aggressive tread tends to be less quiet on paved roads. All Terrain tires are suitable for everyday use.

Mud-Terrain treads are specifically designed with wider tread blocks and higher void ratios to gain traction in off-road conditions. Mud Terrain tires can generate higher noise levels and tend to carry lower mileage warranties than other tread designs.

UTQG - Uniform Tire Quality Grade

UTQG (Uniform Tire Quality Grade) is made up of three values: treadwear, traction and temperature.

Treadwear is a relative numeric score, based on manufacturer tests, showing how well a tire can be expected to wear compared to other tires. A higher score means a tire could be expected to wear better.

Traction measures the tire's ability to stop a vehicle on wet roads. It doesn't reflect a tire's acceleration, cornering, or hydroplaning performance. Traction grades range from AA (highest) to C (lowest).

Temperature grades the tire's ability to withstand heat build-up, with A being the highest grade and C the lowest.

A - Over 115 mph
B - Between 100 to 115 mph
C - Between 85 to 100 mph
Treadwear: 300
Traction Asphalt - gForce
AA - Above 0.54
A - Above 0.47
B - Above 0.38
C - Less Than 0.38
A - Over 115 mph
B - Between 100 and 115 mph
C - Between 85 and 100 mph

Drive / Ride Performance Characteristics

All tires have the following six performance characteristics, divided into three sets of trade-offs. In most cases, a tire may perform excellently in one characteristic but only standard in the other.
Excellent Ride Comfort & Standard Handling
Handling: Get stiff side wall for precise steering and cornering but settle for a firm ride with increased road noise.
Ride Comfort: Enjoy a quiet, smooth ride but lose some cornering ability.
Standard Treadwear & Standard Traction
Traction: Stop faster in wet conditions but expect a shorter tread life.
Treadwear: Get long, uniform wear across your tread pattern but expect less traction in wet conditions.
Standard Low Rolling Resistance & Standard High Speed Performance
High-Speed Performance: Get increased performance at higher speeds but sacrifice some fuel economy.
Low Rolling Resistance: Enjoy improved fuel efficiency but expect less high-speed cornering ability.

Rated 2 out of 5 by Very noisy tire I have this tire with my ACURA 2013. I drove mostly on high way. so it is ready to replace after 90+k. However it has been very noisy for the last two year while I am driving. My wife always laugh at the tire each time she ride the car. I don't know why it so noisy. Should it be covered by warranty, if I choose to replace the same tire? October 16, 2016
Rated 5 out of 5 by Best tires I've ever had!!! I have a 2011 Buick Regal that I bought new with Michelin Pilot MXM4 tires. I drive a long distance to and from work each day and just replaced the tires at 80,300 miles!!! When I had them replaced, I was told I could probably have gotten another 1,000 - 2,000 miles out of them! Unbelievable! I drive about 20K miles per year in my car. I was so impressed with the tires that I replaced them with a new MXM4s. I think I will stick with Michelin tires from now on no matter what car I drive in the future. October 3, 2016
Rated 5 out of 5 by Great Tire Michelin really upgraded the Pilot MXM4. It Looks Great/Way Better Rides With More Cushion handling Slight Improvement from an Already Excellent Handling Tire for my 04 LINCOLN LS Best Ever! This tire is quiet if you think not it's probably your car. July 13, 2016
Rated 1 out of 5 by Horrible road noise, harsh road comfort This tire came factory installed on my 2014 Honda Civic sedan EX-L. The road noise that this tire generates on any surface beyond the smoothest of freshly laid blacktop is horrendous. For awhile, I thought it was a lack of sound deadening in my vehicle. So I went through the expensive, time consuming process of installing sound proofing materials inside of all four doors, thickening the lining underneath the carpeting throughout the vehicle and completely insulating the trunk. All of this combined did almost nothing to reduce the sanity-collapsing road noise! It was these tires all along! Not to mention 4/32" of tread left after 32k miles! February 22, 2016
Rated 5 out of 5 by Great Miles Have 92,000 miles on Pilot MXM4, no problems at all, tires tread looks like it can go up to 100,000 miles This is a great tire. January 7, 2016
Rated 5 out of 5 by 80,900 Miles on Buick Regal I'm just going to replace these tires since winter is upon us with nearly 81,000 highway miles. I regularly rotated every 5,000 miles and wouldn't consider any other tire for my Buick Regal. Great product! January 4, 2016
Rated 5 out of 5 by I got 80000 out of these and still going. I would like to thank Michelin for making such an awesome tire. Keep up the good work. I haven't had one problem. Great tire. Thank you Keith Wittig October 8, 2015
