Platin RP 420 review

The Platin RP 420 is generally regarded as a high-value budget tire that delivers impressive dry and wet grip for its price point. While most users are satisfied with its performance and longevity, the consensus is marred by reports of significant road noise and a lack of steering precision due to soft sidewall construction.

The Platin RP 420 is generally regarded as a high-value budget tire that delivers impressive dry and wet grip for its price point. While most users are satisfied with its performance and longevity, the consensus is marred by reports of significant road noise and a lack of steering precision due to soft sidewall construction.

Pros

  • Excellent price-to-performance ratio
  • Reliable grip on both dry and wet road surfaces
  • Commendable tread life even under spirited driving conditions

Cons

  • Excessive road noise levels
  • Lack of steering precision and handling feedback
  • Soft sidewall structure that feels unstable under load

Worth knowing

  • Users noted that the XL-rated sidewalls do not provide the expected stiffness, leading to a feeling that the tire struggles to support the vehicle's weight during cornering.
