Toyo Proxes RA-1 Tires

Consumer Advisory and Safety Information:

1. The tread compound on the Proxes RA-1 is designed to operate under racing conditions.
2. To achieve optimum adhesion levels the tread must operate within a narrow temperature range.
3. This temperature range is very difficult to achieve under legal and normal street operating conditions.
4. The Proxes RA-1 tire starts with a tread depth of 8/32 of an inch which is approximately 2/3rds of the depth of a premium all season tire.
5. The combination of shallower tread and temperature sensitive tread compound requires the user to be fully aware of the performance limitations of the tire under normal legal street use.
6. The performance limitations are particularly evident during low ambient temperatures or during times of the year when the ambient temperatures fluctuate considerably as in the spring of fall periods.
7. Wet performance limitations are also evident on damp or wet roads when operating outside the optimum temperature.
   
   
   Technical:
   • Best operating temperature 160 to 220 degrees F. Higher than 220 degrees F the tire performance will start to go off, although temperatures as high as 300 degrees F have been seen before blistering takes place.
   • Camber: Negative 2.5 degrees to negative 5 degrees acceptable. Anything less than 2.5 degrees or higher than 5 degrees negative will create some irregular wear.
   • Pressures: Front Wheel Drive start no less than 24psi. Rear Wheel Drive start no less than 18psi. Goal is 41 to 43psi hot.
