Edit:I tried to paste the pic of the formula, but it looks like its not gonna take. Anyway the formula for a 23mm rear tire is...

(rider weight in lbs x .33) + 53.33= rear tire psi

To find the psi for the front tire, simply multiply rear tire psi x .9

Example (135lbs x .33) + 53.33=97.88psi (rear tire)
97.88psi x .9=88.09psi (front tire)

Again, these are merely starting points. Hope this helps.
