The Proxes RA1 is Toyo’s Dry Racetrack & Autocross Only tire developed for drivers looking for street-legal circuit tires that combine consistency, durability and competitive times. Proxes RA1 tires are designed to provide an uncommon advantage to cost-conscious competitors who demand quick lap times and long tire life from their racing tires.
While Proxes RA1 radials meet DOT requirements, they are not appropriate for highway use. Proxes RA1 radials are not recommended for driving in wet conditions when shaved or worn where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions. And like all Dry Racetrack & Autocross Only tires, Proxes RA1 radials are not intended to be driven in near-freezing temperatures, through snow or on ice. It’s also essential these tires be stored indoors at temperatures maintained above 15 degrees F.
Proxes RA1 tires feature a soft but durable R-Compound that is tolerant to repeated heat cycles. This compound is molded into a symmetric stepped tread design that delivers competitive handling and performance. When new with 8/32” of tread depth, the tire features an independent tread block and groove arrangement that emphasizes wet traction. Shaving to reduced tread depths increases direct contact with the track to improve dry traction. Dry traction is enhanced at 6/32”, lateral grooves disappear at about 4/32” and only two central circumferential grooves remain when worn to 3/32” to deliver the best dry traction.
The tire’s internal structure features an advanced competition modified radial construction for driving hard through the corners and accelerating quickly onto the straight-aways.
Toyo Tires recommends the following general set-up guidelines for the Proxes RA1:
- Operating Temperature: 160°F to 220°F
- Hot Inflation Pressures: High 30s to Low 40s (psi)
- Camber: -2.5° to -5.0°
- Caster: As much positive as possible
El neumático Proxes RA1 de Toyo pertenece a la
categoría: Solo Para Pista y Autocross En Seco, y fue desarrollado para
conductores que necesitan neumáticos de circuito, que puedan ser
usados legalmente en las carreteras y combinen durabilidad, consistencia
y tiempos competitivos por vuelta. El diseño del Proxes RA1
proporciona una ventaja poco común a entusiastas que ven la
realción costo/rendimiento y demandan menores tiempos por vuelta
y una vida larga del neumático de carrera.
A pesar, que los
radiales Proxes RA1 cumplen con los requisitos DOT, estos no se
recomiendan, para su manejo en autopistas. Tampoco en condiciones
mojadas, si están afeitadas o gastadas y haya agua estancada y la
posibilidad de patinazo (hydroplaning). Si estas condiciones
están presentes, los conductores deben disminuir la velocidad
cautelosamente. Y como todo neumático del segmento: Solo Para Pista y Autocross En Seco,el Proxes RA1, no fue diseñado para ser utilizado en temperaturas
cercanas al nivel de congelación o superficies con hielo o nieve.
Además, es esencial que cuando sean guardados, la temperatura
debe mantenerse por encima de los 15 grados Fahrenheit (9 grados
Celsius).
Los neumáticos Proxes RA1 poseen un compuesto de
caucho, suave pero durable, conocido como R-Compound y que tolera ciclos
de calor repetitivos. Este compuesto, es moldeado en una banda de
rodamiento con diseño simétrico escalonado, el cual,
proporciona un rendimiento y maniobrabilidad competitiva. Cuando la
banda de rodamiento es nueva, posee una profundidad de 8/32” (6.4mm),
segmentos de bloques independientes y ranuras que ayudan a sacar el agua
de la huella, para mejorar la tracción sobre superficies mojadas.
Al afeitarlos aumenta el contacto con la pista, mejorando la
tracción sobre superficies secas. Esta tracción, mejora a
una profundidad de 6/32” (4.8mm); las ranuras laterales desaparecen
acerca de una profundidad de 4/32” (3.2mm) y cuando esta desgastado a
una profundidad de 3/32” (2.4mm) solo permanecen dos canales
circunferenciales centrales, para ofrecer la mejor tracción sobre
superficies secas.
La estructura interna del RA1 posee una
construcción radial de competencia modificada, para conductores
que conducen ferozmente, al tomar curvas y aceleran rápidamente hacia
las rectas.
Toyo Tires recomienda las siguientes guías
generales de configuración para los Proxes
RA1:
- Temperatura de operación: 160°F hasta 220°F
(71°C hasta 104°C)
- Presión de inflado en caliente: 30
altos a los 40 bajos (psi)
- Ángulo Camber (comba):
-2.5° a -5°
- Ángulo Caster: Tanto positivo como
sea posible
