What is the concept of Michelin rating?

[StRhett]

Michelin rating refers to the high quality and durability of car tires. The following is an introduction to Michelin: 1. Basic information: Michelin (MICHELIN) is a tire manufacturing company founded in 1889 in Clermont-Ferrand, France. In 1898, the Michelin Man "Bibendum" was born. In 1946, the radial tire was invented. In 1993, the C3M tire manufacturing process was invented. In 1995, the first joint venture in China, "Michelin Shenyang Tire Co., Ltd.", was established. In 1996, the PAX-System tire was invented. 2. Fortune ranking: In May 2021, the "2021 Forbes Global 2000" was released, with Michelin ranking 470th.

Last time when changing tires, the technician mentioned Michelin's grading system to me, which mainly refers to tire performance indicators. For example, sports tires like the PS4 have a lightning bolt symbol on the sidewall, representing the highest traction grade of AA, which can shorten wet braking distance by several meters. Common family car tires like the XM2+ are economical and wear-resistant, with low noise but weaker handling. The most extreme are the slick tires used on racetracks, which have no tread patterns at all and rely entirely on thermal melting adhesive. When choosing tires, don't just look at the brand; match them to your needs—if you often drive on highways, choose AA grade, while for urban commuting, quieter B grade tires are more cost-effective. Nowadays, newly released self-sealing tires even have a small umbrella symbol on the sidewall.

I remember being terrified during a rainy day skid, which led me to thoroughly research Michelin's 3T tire standards. A tire with a Treadwear index of 160 is much softer than one rated 320 – a favorite among speed enthusiasts but wears out quickly. The Temperature rating ranges from A to C for heat resistance, with grade A being the best choice for mountain driving. The most crucial factor is the Traction rating; after upgrading my SUV to AA-rated tires, it climbs snowy slopes as steadily as if it were a different vehicle. Now when choosing tires for my wife's car, I always check these three criteria – far more practical than just judging by tread patterns alone.

My mom always thinks Michelin only makes premium products, but actually their Energy series focuses on fuel efficiency and durability. When I changed tires for her Polo last time, I found the same size comes with different speed ratings like H/V/W. For regular city driving, H-rated tires supporting 210km/h are sufficient, but frequent highway driving requires V-rated tires with a 240km/h limit. There's also a load index hidden on the tire sidewall - 85 corresponds to 500kg. Since elderly folks don't understand these parameters, just remember to choose city tires with the green fuel-saving label, and pick mountain-patterned off-road tires for SUVs.

My friend who's into car modifications taught me the secrets of Michelin performance tires: The Pilot Sport series uses dual-casing technology, where the sidewalls hardly deform during cornering. The track version, CUP2, even has different rubber compounds for the inner and outer sides—the outer side becomes stickier as temperatures rise. Regular street tires have 5 layers of crown plies, while off-road tires like the AT2 increase to 8 layers for puncture resistance. The most amazing part is their noise-canceling tech—some premium tires have polyurethane foam attached to the inner walls, which can absorb up to 75% of tire noise at high speeds, far more effective than adding soundproofing foam.

Back when I was a test driver, I handled tires every day. Michelin's grading system is like the 'Ti' suffix on graphics cards. The regular Primacy is the entry-level model, the PS4 has sporty attributes, the PS4S reinforces shoulder support, and the top-tier CUP2R is straight-up semi-slick. I remember testing the CUP2—it could still grip the track even at 60°C ground temperature, but driving on these tires in the rain is like skating. Nowadays, the new EV-specific tires on the market have particularly dense tread patterns, handling electric vehicle torque more steadily, and they even add a little lightning bolt logo on the side.
