Toyo Proxes RA1 Tire
Built for serious enthusiasts and grassroots racers, the Toyo Proxes RA1 pairs track-ready pace with real-world convenience. This DOT competition tire uses a track-focused compound and a semi-slick, directional tread to deliver steady grip, linear breakaway, and clear feedback near the limit. It warms up predictably, resists chunking when managed well, and remains street legal so you can drive to the circuit. Whether you run HPDE, time attack, or spec racing, the RA1's consistent feel and stout construction make it a dependable partner for learning lines, dialing setup, and clicking off repeatable laps.
Key features of the Proxes RA1
The Proxes RA1 is built for repeatable performance and durability in track heat. A competition compound provides dependable grip once warmed, and the semi-slick, directional pattern maximizes rubber-to-road contact with broad shoulder blocks for cornering stability. Wide circumferential grooves help clear standing water at moderate speeds, which adds flexibility for damp sessions. A reinforced carcass sharpens steering response and promotes even wear with correct alignment and pressures, and many drivers value its linear, predictable breakaway that makes setup changes easy to feel.
On-track performance and street use
Expect a steady warm-up and confidence-inspiring feedback as the RA1 comes into its window. It rewards smooth inputs and consistent pressures, delivering stable mid-corner grip and trustworthy braking feel. In light rain or on a damp track, the grooves provide some drainage, but hydroplaning resistance in heavy water is limited compared with street tires. While street legal, the RA1 prioritizes lap time over comfort and noise. For best results, monitor hot pressures, run a cool-down lap, and rotate often to keep wear even across events.
Sizes and fitment guide
The Proxes RA1 comes in popular enthusiast and spec-racing sizes used on lightweight sports cars and track builds. Common options include 205/50r15 and 205/60r13, with additional sizes such as 225/50r15 and 255/50r16 available in select applications. Always confirm clearance, wheel width, and load and speed ratings for your vehicle. Check the OE tire placard in the driver-side door jamb and review your alignment and wheel setup before ordering, and ask if you need help choosing square or staggered fitment.
Treadwear, heat cycles, and longevity
The RA1 carries a low UTQG rating typical of DOT competition tires. Verify the exact marking on the sidewall for your size, but expect longevity to be driven more by heat cycles, track surface, camber, and pressures than by the number. To maximize life, allow proper cool-downs, store tires away from heat and UV, and rotate across axles to balance wear. Some drivers shave the tread for quicker warm-up and more consistent dry grip, which reduces wet capacity and overall depth, so monitor temps and adjust setup to avoid hot spots.
Price and how to buy
Pricing for the Toyo Proxes RA1 varies by size and availability. Select your size, confirm quantity, and check live stock before checkout, and consider a full set to simplify rotation and keep performance even across axles. If you need help with sizing or heat-cycle strategy, our team can advise based on your wheels, suspension, and events. Fast shipping and optional mounting and balancing make it easy to arrive track ready.
Toyo Proxes RA1 vs R888R
Both are DOT competition tires built for track work, but they emphasize different traits. The Proxes RA1 delivers linear handling and steady performance across long sessions, which makes it friendly for learning and setup. The R888R targets peak dry grip and quick response for hot laps. If you value consistency and a forgiving breakaway choose the RA1, and if you want maximum turn-in bite with a time-attack focus consider the R888R, keeping class rules, climate, and driving style in mind.
When the RA1 makes sense
Choose the Proxes RA1 if you value repeatable laps, easy-to-read feedback, and a steady balance as temperatures build. It suits HPDE, time trials, and spec formats where consistency and drivability help you progress. Drivers who trailer or drive to the track appreciate its street legality, and the semi-slick tread supports dry pace with some flexibility in damp conditions. If you want a tire that communicates clearly while you refine lines and setup, the RA1 fits the brief.
