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
17/100From 18 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.

The Radar RPX900 receives a polarized mix of reviews, praised initially for its low price, smooth ride, and low cabin noise, but heavily criticized for long-term durability and high-speed stability issues. While budget-conscious drivers with relaxed driving styles find them to be an affordable and comfortable option, others report premature tread wear, excessive noise over time, and severe vibrations or soft sidewalls at highway speeds.
Pros
- Affordable, budget-friendly price point
- Exceptional ride comfort and smoothness
- Very low noise levels when new
- Adequate dry and wet traction for normal, everyday driving
Cons
- Soft sidewalls causing a floating or 'balloon-like' sensation at highway speeds
- High-speed wobbling, shaking, or balancing difficulties
- Rapid tread wear and increased noise over time
- Quality control issues including sudden air loss or sidewall bubbling
Worth knowing
- Owners of smaller B-segment vehicles like the Volkswagen Golf and Proton Iriz generally reported satisfactory comfort and grip during normal city driving.
- Drivers emphasizing high-speed highway travel experienced severe discomfort due to soft sidewalls and stability loss at speeds above 60-70 mph (120 km/h).
