Does anybody run the RE71-R on their 914 for autocross? I couldn't find any thread
discussing pressures. Going to these from hoosier for this year. Narrow body car, so I am using 205/45/16. Based on other types of cars , search of other sites leads me to think high 20's for a light car. |

The lighter the car the less pressure. I was using 14.5 pounds in the front and 15 pounds in the rear in a car that weighted under 1650 pounds. Kumho's 225/50/16's. The guy's I asked running this tire on 911's were running 31 psi. I think the car was over 3,000 pounds. A pyrometer is your best friend. It will help you get your tires on the ground. I take measurements in 3 places (inside, center and outside) on each tire and adjust the camber and air pressure to make the measurements all within 10° watching for scuffing on the edge of the tires.
Did all that make any sense? Joe |
