tire pressures

It's kind of a dumb question but I was wondering which tire should be set with higher pressure? I've seen posts where some set the front higher and others who set the rear higher. Is there an actual correct setting or is it down to the feel the rider gets?

I've run my S20s with higher front than rear (31/28) but I'm on 003 now and was thinking of running higher pressure (maybe 36/34) to get more life out of them.

It depends on what/how you're riding;
For track/road course use the front will be higher. For top speed or two up riding the rear will be.

The higher rear for top speed is due to the higher pressure effectively giving the rear a larger diameter?

Cool, I liked the was the S20s felt at the lower pressure but being that the 003 are softer I figured that higher pressures would help extend the life of them.

Depends on the tire and type of riding. For highway cruising or commuting i run 36f and 40r. Brisk weekend rides are usually 32f 30r. Track is a whole different story and brands play an important role. Just check the manufacturer recommendation and go from there.

And also to keep the tire cooler so it doesn't self destruct. Higher pressures=cooler tires.
