914World.com _ 914World Garage _ Tire Pressure Question

Posted by: Racing916 May 23 2005, 06:38 AM

Hello,

I have a question regarding Tire Pressure for a DE event. We usually track a 4 cyl car with R compund tires 27psi in front and 28 psi in back cold at Watkins Glen. We have now built a 6 and put on 15X7 and 15X8 wheels. the tires are Yokohama ES100. What would be a good pressure for these tires. 28? 29? cold.

Thanks,
Steve

hey Steve!
I don't know about the tire pressures, maybe this will BUMP someone into responding...
I hope to check out your car at the Glen this weekend!

Dont know about those tires, I currently am wearing out a set of A032 yokahamas

After a few sessions at Watkins Glen last weekend I ended up after some playing around running 31lbs front left 33 lbs front right, 33 lbs right rear, 33 lbs left rear.

hot temps grew to almost 40 lbs each, and pyrometer readings were good
