Michelin Primacy MXM4 Performance
The Primacy MXM4 by Michelin is a all-season tire with an overall rating of 3.9 / 5. This places it in spot #56 among the 91 all-season tires we’ve reviewed.
Dry Performance Rank
The Primacy MXM4 received a Dry Performance rating of 4.4 / 5. This ranks it #52 among the 91 all-season tires we’ve reviewed.
Considering this, you may be underwhelmed by its performance on dry roads. However, it may perform well in other categories.
Wet Performance Rank
The Primacy MXM4 received a Wet Performance rating of 4.2 / 5. This ranks it #43 among the 91 all-season tires we’ve reviewed.
Considering this, you may be underwhelmed by its performance on wet roads. Other buyers have not been overly pleased with their traction and hydroplane resistance.
Comfort Performance Rank
“Comfort” performance relates to the tire’s quietness, and smoothness. Better ratings will keep tire ‘roar’ or road-noise to a minimum. Great for luxury cars, or anybody looking for a quieter cabin.
With a Comfort Performance rating of 4.2 / 5, the Primacy MXM4 is ranked #44 among the 91 all-season tires we’ve reviewed.
This rating implies the tire is louder than most on the road, and/or typical buyers of this tire were generally used to quieter and smoother tires. It’s likely Michelin was not focused on reduced road noise for the Primacy MXM4.
Treadwear Performance Rank
Treadwear performance is a measure of how well the tire matched up to customers’ expectations of how many miles they will last. Keep in mind, this rating can be influenced significantly by users giving it 1-star or 5-stars because expectations were too extreme. Maybe their last set of tires lasted 100,000 miles and they now think all tires will last that long (that’s extremely rare). Or perhaps their alignment was really off, causing them to wear out in only a few thousand miles.
The Primacy MXM4 received a Treadwear Performance rating of 3.7 / 5. This ranks it #69 among the 91 all-season tires we’ve reviewed.
With this rating, most buyers were not very happy with how long this tire lasted. If you’re looking for a long-lasting tire, best pick something else.
UTQG Rating: What does 500 AA A Mean?
The UTQG Specification is also relevant to discuss here. This is a specification provided by the manufacturer after testing. The rating for this tire is 500 AA A. There are three parts to this specification: treadwear grade, traction grade, and temperature grade (in that order).
The treadwear grade for this tire is 500. This treadwear grade is very high. This implies the rubber compounds are relatively hard compared to other tires. This tire should wear very slowly – however the trade-off here is usually poorer dry and wet traction.
The traction grade for this tire is ‘AA’. This is a great rating, and implies the tire can handle high g-forces before starting to skid.
The temperature grade for this tire is ‘A’. This rating refers to how well the tire dissipates heat at high speeds. If the tire gets too hot at high speeds, it may come apart. Keep in mind, these speeds are very high, and any tire manufactured these days is capable of maintaining highway speeds up to 80mph.
This is the highest temperature grade rating. An A rating here suggests the tire is temperature-stable at speeds over 115mph. Slow down!
Snow & Ice Performance
Snow/Ice Performance Rank
Snow and Ice performance is tested on a specifically designed track to simulate these environments. These ratings represent how confident drivers in these conditions felt on these tires.
The Primacy MXM4 received a Snow & Ice Performance rating of 2.9 / 5. This ranks it #64 among the 91 all-season tires we’ve reviewed.
These tires did not perform very well in the snow and ice category. If you do see these conditions often, we recommend looking for a different tire. If you only occasionally see light snow, just be cautious on these tires when you encounter it.
Off-Road Performance Rank
The off-road ratings represent how satisfied other drivers were in these conditions. These conditions could include anything from dirt/gravel roads to extreme offroading/bouldering. If you intend to use these in more extreme conditions, we always recommend checking individual reviews on TireRack.com for specific examples.
The Primacy MXM4 is not rated for off-road conditions, we do not recommend attempting anything beyond casual dirt roads on this tire.
Michelin does offer a treadlife warranty for this tire. You should see a time-frame and mileage provided in the ratings on this page. Note that this is a ‘whichever-comes-first’ scenario. So if it’s listed as 3 years, 50K miles – they can be warrantied as long as they are less than 3 years old AND have less than 50K miles on them. Manufacturer’s generally determine if a tire is claim-able for warranty by measuring remaining tread depth. See the documentation for the tire for more information.
