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.

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.

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

  • Users driving smaller, lighter vehicles (e.g., B-segment superminis) report higher satisfaction with grip and comfort.
  • Owners of larger or heavier vehicles report more pronounced issues with sidewall flex and high-speed instability.
