Setup Guidelines
Toyo Tires recommends the following general set up guidelines for the Proxes RA1:
- Operating Temperature: 71°c to 104°c (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
- Shaving: 4/32” is recommended for competition (grooves remain until 2/32”)
- Rim width: a tire size that falls within the range of midpoint to maximum rim widths is recommended
Proxes RA1 Safety Advisory
- The tread compound is specifically designed to operate under racing conditions making it difficult to achieve optimum adhesion levels under normal street driving.
- The shallower tread depth of 6/32nds limits the tire’s performance capabilities under normal street driving conditions.
- Performance limitations are particularly evident in low ambient temperatures or during the spring and fall when ambient temperatures fluctuate significantly.
- Wet performance is limited when operating outside the optimum temperature range, and when the tire is at less than full tread depth.
- Do not use the tire if it has cracked.
