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
79/100From 10 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
40/100Scaled across every tested tire: the average gets 70, the best 100.

The Marshal MU12 is widely regarded as a high-value performance tire that punches above its price point, offering impressive grip and handling characteristics that rival more expensive premium brands. While some users report increased road noise and a firmer ride quality compared to luxury-oriented tires, the consensus highlights its excellent stability and responsiveness across various vehicle types.
Pros
- Exceptional dry and wet grip performance for the price point
- Precise steering feel and responsive cornering
- High value-to-performance ratio compared to premium brands
- Strong stability and planted feel at highway speeds
Cons
- Higher road noise levels than some premium touring tires
- Firmer ride quality which may impact comfort for some drivers
- Potential for slight decrease in fuel economy
- Noise levels may become more noticeable as the tire wears
Worth knowing
- Drivers of high-performance AWD vehicles and SUVs (such as the BMW X5) noted a firmer ride and increased road noise, though they praised the responsive handling.
- Users transitioning from factory-fitted tires on mid-size sedans like the Kia Sportage and Toyota Camry reported immediate improvements in steering confidence and cabin quietness.
