Whole lot 'O 914/6  Group: Members Posts: 157 Joined: 15-November 04 From: Mount Pleasant, SC Member No.: 3,122  |
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! |

I'll ask the same question people asked me a year ago when I had this same question..."what brand/size of tires are you running?"
I started with old, worn out, hard 205/60's and had to put almost 60lbs in them to keep them from "rolling over". Now with 205/50 Falkens I run around 40lbs. My suggestion for street tires (based on some of the comments on the club lately...it is just a suggestion (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) ) is to add 10 or 15 lbs to your tires, then mark the edges with chalk or shoe polish (although shoe polish is a b*tch to get off) and check the sides for scrubbing. Add pressure until there is no significant scrubbing on the side. Or probabally the best idea is to just put 15 extra lbs. in. Go to the autocross and have a great time and get plenty of driving practice. Hopefully a few of the more experienced autocrossers will chime in (IMG:http://www.914world.com/bbs2/html/emoticons/pray.gif) Have fun!! David |
