From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Falken FK451 is widely regarded by users as a high-value performance tire that punches well above its budget-friendly price point. Owners consistently praise its balanced dry and wet grip, impressive tread longevity, and refined road manners, often comparing it favorably to premium brands like Michelin and Pirelli.
Pros
- Exceptional price-to-performance ratio
- Strong wet and dry traction
- Excellent tread life and durability
- Low noise levels and smooth ride quality
Cons
- Potential for rubber cracking between treads over long-term storage or extended age
- Some users report a slightly less 'alive' or communicative steering feel compared to premium performance tires
- Availability concerns as it is an older model often superseded by newer iterations
Observations
- High-horsepower vehicles (300bhp+) and heavy luxury sedans (W140 S-Class) report stable, reliable handling.
- The shoulder profile is noted as being particularly friendly for owners of lowered vehicles, preventing rubbing issues.
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.
