I am going to run my 914/6 in my first autocross this saturday. Everyone in racing seems obsessed with tire pressures. I have no idea where I should set them or if they should be set hot or cold.
Can anyone please explain the pressure obsession to me so that I can be equally neurotic. Thanks! |

Ken, I'm going to assume you are talking about street tires. One pushes the car a lot harder on an AX course than on the street. As previously mentioned, you want them hard enough that they aren't rolling over on the sidewalls during hard cornering. You want the contact patch as flat as possible.
FWIW, I have 205-50-15s street tires on my 914 and 33/36 seemed to work well at the last AX I did. |
