From owners

Pros, cons & observations

Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.

Tire A Goodyear Eagle LS-2 RunOnFlat

Not enough owner reviews yet to extract themes.

Tire B Michelin Primacy MXM4

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.

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

Observations

  • 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.

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
