The Michelin Primacy MXM4 is generally regarded as a comfort-oriented grand touring tire that excels in ride quality and tread longevity but falls short for performance-minded drivers. While users praise its ability to dampen road vibrations and maintain durability, many report lackluster handling, significant understeer, and underwhelming wet-weather traction when pushed.
Owners rate it 14.2 points lower than the instrumented road tests do — see the two score breakdowns below for where they disagree.
Two scoring systems, side by side
Owner scores come from reviews found online; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.
How scores work
- Relative score
- 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
- Road tests
- 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
- Owner reviews
- 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.
By owner reviews
57/100From 10 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
71/100Scaled across every tested tire: the average gets 70, the best 100.

Pros
- Exceptional ride comfort and vibration dampening
- Strong tread life and durability
- High fuel efficiency
- Effective resistance to aquaplaning in heavy rain
Cons
- Mediocre dry grip and handling precision
- Noticeable understeer when cornering
- Soft sidewalls that lack steering feedback
- Increased road noise on certain surfaces
Worth knowing
- Drivers of high-torque FWD vehicles report significant wheelspin and traction issues in wet conditions.
- Tesla Model 3 owners noted a decline in handling performance compared to dedicated summer tires, suggesting the tire is better suited for comfort than spirited driving.
- The tire's run-flat variants are noted for maintaining a surprisingly soft and compliant ride despite their reinforced construction.
