Pros, cons & observations

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.

Tire A Proxes RA1

Pros

  • Exceptional dry grip that remains consistent even as the tread wears down.
  • Superior tire life compared to many other dedicated track-focused compounds.
  • Predictable breakaway characteristics that provide driver confidence at the limit.

Cons

  • Performance can become 'greasy' if the tire is overdriven or overheated during long sessions.
  • Requires proper heat cycling and break-in procedures to achieve optimal performance.
  • Sensitive to alignment settings, which can lead to accelerated or uneven wear if not managed.

Tire B Proxes T1 Sport

Pros

  • Exceptional dry and wet grip for confident cornering and braking
  • High level of ride comfort and shock absorption, outperforming stiff run-flats
  • Lower price point compared to top-tier premium competitors while maintaining comparable performance

Cons

  • Rapid tread wear and short lifespan, with many users reporting the need for replacements well under 15,000 miles
  • Softer sidewalls can lead to a less direct or squirmy feel during aggressive cornering
  • Occasional sensitivity to road grooves, uneven surfaces, and standing water (hydroplaning tendencies)

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
