Radar RPX900 review
The Radar RPX900 is a polarizing budget-tier tire that excels in comfort and noise reduction for casual, daily driving. While many users praise its value and ride quality, a significant portion of owners report severe issues with sidewall stability and high-speed handling, suggesting it is best suited for low-speed urban environments rather than highway use.
Two scoring systems, side by side
Owner scores come from reviews on retailer and review sites; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.

Pros
- Excellent ride comfort and low noise levels
- High value for money for budget-conscious buyers
- Satisfactory dry road grip for normal, non-aggressive driving
- Good tread longevity under moderate driving conditions
Cons
- Excessively soft sidewalls leading to a 'floating' or 'balloon-like' sensation
- Poor high-speed stability and handling characteristics
- Inconsistent quality control regarding tire balance and air retention
- Not suitable for performance or high-speed highway driving
Worth knowing

- Owners of larger or heavier vehicles report more pronounced issues with sidewall flex and high-speed instability.
