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.

Do you have a question about Proxes RA1 235/40ZR17?
Toyo Proxes RA1 tires are primarily manufactured in the USA at Toyo's White, GA factory, though some may also be produced in other locations around the world.
Yes. The Proxes RA1 is DOT approved and street legal in most areas, but it is a competition-focused tire, so ride comfort, noise, and tread life take a back seat to grip and feedback. Wet and cold performance is limited compared with all-season or summer street tires, and hydroplaning resistance in heavy rain is modest. If you will drive on public roads, warm the tires gradually, avoid standing water, and never use them in freezing or snowy conditions while following local regulations and manufacturer guidance.
Shaving reduces tread squirm, speeds warm-up, and can improve dry-track consistency, but it also shortens total tread life and lowers wet safety margins. The choice hinges on your priorities, event format, and typical conditions. If you run mostly in dry, predictable weather and want sharper feel, shaving is common. If rain is likely or you drive to the circuit, keeping full depth is safer, so discuss your goals with a tire specialist before deciding.
The RA1 is produced in popular enthusiast sizes used for track days and club racing. Common examples include 205/50r15 and 205/60r13, with additional options such as 225/50r15 and 255/50r16 depending on availability. Stock varies by region and season, so use the size selector to check live inventory. Confirm wheel width, offset, and clearances, and reference the OE placard on the driver-side door jamb, or ask our team for help choosing square or staggered setups.
Lifespan depends on track surface, driving style, alignment, and heat-cycle management. With correct pressures, rotation, and cool-down laps, many drivers see several events of consistent performance before grip begins to taper. Aggressive camber and high temperatures will accelerate wear. Store tires in a cool, dark place between events, and plan replacements based on feel and lap consistency rather than tread depth alone.
The RA1 carries a low UTQG value typical of DOT competition tires, and the exact number can vary by size and production. For the most accurate information, check the UTQG marking on your tire sidewall and the product label. UTQG is not a direct measure of track longevity, since heat cycles, alignment, camber, pressures, and driving style have greater impact. Proper rotation and cool-down procedures help maximize usable life.
Fitment depends on your car's OE specs, wheel width and offset, suspension geometry, and alignment. Start with the OEM size on the driver-side door-jamb label, then confirm wheel specs and fender clearance. Many track setups move to a square fitment for rotation flexibility, but some cars need additional camber or fender work to make that happen. If you are unsure, share your wheel size, offset, and ride height with our team for a confirmed recommendation before ordering.
