...depends on tube, tire, rim, how skilled you are and many other variables...I would say anywhere from 10psi to 30psi

I suggest you start at the max psi for your tire (listed on sidewall)...

..and don't be surprised if you destroy your wheel anyway.

Haha, don't even go less than 40 psi. I'm about the same weight, and I hit the rims if I have much less than 40.

Run your rear at 50-60ish and your front 40-50ish.

I just gave my wheels to my LBS wheel guy to work over. He told me that he could tell that I've been doing stairs b/c my wheels have some flat spots in them. I usually only run 35-40 psi when I ride trails. I didn't air them up any more than that when I went out to the stairs the other day because I'm a freakin' bonehead.

I'm 6'1" 185 pounds. He said I should be running 50psi. I'm running 2.1's and I really should be on 2.4's for that kinda stuff. I think I'm going to get me some of those Kevlar Panaracer Fire FR pro's 2.4's.

chelboed - not bad but this is still my favorite.




I'm still waiting to see someone with some skill ride the handrail on it.

Dang...that looks like fun!!!!

Yeah, I don't gap the one I posted yet. I do catch some air off the top and land a couple feet from the bottom though. (usually the second set)

There's a decent run about 100ft long before you get to it...I'm not sure if it's enough to clear the flat or not. Until I get a freeride bike, I guess I won't know. I just have a 5" trail bike that I built from scratch that has no warranty against having too much fun.

I hope you're not talking to me.

You jump off the top and land on the middle of the second staircase. Roll down to the flat.

Either that, or hit at an angle and jump off the top, clear the rail and land on the grassy hill.

I was talking to you. Your first post read like you wanted to clear it all and land to flat

Oh my heavens to Betsy! That would be a Very Merry Bender thing to do. I guess if I could get a Trek Session 20 with those Surly Large Marge wheels and pump them up to 150psi. Maybe...just maybe...I'd chicken out.

Yeah, I hate landing to flat. Even on 3 footers...I hate it. I can just hear my wheels crying out to daddy. Stop the spanking, stop.

It don't think it really matters. I wouldn't have it flat, or near. I would have it really PUMPED!
