42 rear and 36 front.
I got 13k out of a stock front, running irregular 36 but I will make a concerted effort to keep it at 36 these days. Remember: 1 PSI increase/decrease for every 10 degrees F from the temperature at time of refill plus (algebraically) 1 psi loss per month.
I run DynaBeads in the rear alone (no extra weights) and it's as smooth as glass. It hasn't been long at all since the darkside took me away. The next front change out I'm going to the beads in the front as well.
I VERY much like the normal ride profile (comfy w/ no counter steering of a stocker rear); I say this Cooper Zeon 2XS is a STRAIGHT tracker. If there is any crown in the lane you will be increasing you muscle mass. I love it in any case. No doubt the full torque is NOT sloughing off aswas clearly the case with the soft Metzler.
This bitch bites!

Butt, it is a hand full at the local flea market parking

.
Though, I won't trade it for 2 years of stockers skins. Make that three years of stockers. I've put a lot of miles on my FBG thus far and I find no satisfaction in the regular recurring PITA of replacing a stock Metz. F'em. I ride as hard as I like now and don't give a...care about melting off the rear. The fact is, it DON'T happen.
It takes a bit of getting use to but so is the power!!
