Quick! Please! What PSI for Pirelli Sport Demons?

I way 135 lb. and I'm running Pirelli Sport Demons, 110/70/17 front and 140/70/17 in the rear. Best pressure?

Owners manual says 28 front / 32 rear with the OEM tires. If you're at that, it will be fine. Some people use a bit more; I think I saw a doc where Pirelli recommended something like 30 front / 34 rear for the sport demons.

Yeah. Their site said 2 Bar (30 PSI) front, 2.5 Bar (36 PSI) rear. But the shop that installed them set them both to 30 PSI. And I was familiar with the OEM levels, which confused me. Thought I'd ask what the Sport Demon guys here are running.

Tire pressure is really a matter of personal preference. I prefer softer tires, but within the safe zone, so tend to run them at lower pressures than recommended. 30/30 cold is usually pretty safe with most tires.

It was suggested to me to run 30/34 on my SD's but I didn't really like the feel.
Dropped mine to 29/32 for my tastes... everyone has their own preferences.

I thought I read on their website 32-36. Thats what I run and I find the bike seems a lot more stable at those pressures and seems to soak up the bumps a bit better?
