What air pressure do you run....
- Thread starter stosh
- Start date
Depends on the conditions of the trail and the tires/tubes I'm running.
Full Suspension
20front
23 rear

Bikey A - Light XC full squishy. Hutchinson Aligator Gold 1.85 50PSI front 45PSI rear. Going up bike.
Bikey B - Heavy Duty XC full squishy, short travel, Moto Raptor 2.4s 35PSI rear 28PSI front and sometimes... lower. Going down bike.

i agree with tweak! all depends on conditions!
but usually.. for my dual sus for XC.. i run 40-45 psi rear, 45-50 front. i almost always run kenda kharisma lite 1.9 on the rear and 2.1 front. if it's really hard packed i run 1.9 klimax lite on the rear @ 45-50 psi.

Single Speed hardtail with front suspension, running Stan's No-Tubes 35-38 psi in front, 38-40 psi in rear, all depending on the conditions as someone said earlier. Also it might help if people gave their weights too, I am 190-195 lbs right now, still a fat a$$ from the winter.

Same here.
I usually run about 40.
I may kick it up to 45.
Another question whats the best way to seat a tubeless tire. I got a slow leak in the rear.
XC FS:40-42 front & rear
DH FS:20-25 front & rear
DH FS:20-25 front & rear
I take an old windex bottle and mix up some dishwashing liquid and water, then spray the bead down good with it and use compressed air. At first I air it up to about 60-65 psi and let it set over night or so, that usually seats them fine... If you're running stan's then the latex should seal it off...
DH bike: Full suspension, inner tubes.
- Trail/freeride - 30F / 35R
- Urban - 45F / 45R
- Racing - 25F / 30R
XC bike: Full suspension, UST tubeless.
- Trail - 35F / 35R
- Racing - 40F / 40R
Road bike: No suspension, inner tubes. 100F / 100R
BMX bike: No suspension, inner tubes.
- Skatepark - 70F / 70R
- Jumping - 50F / 50R
Really it totally depends on the conditions and type of riding, experiment and figure out what you like, keep a good floor pump with a gauge with you, and make it a point to check your pressures before every ride

FS: 45/45
I am not an advanced enough rider to feel the difference between 45 psi and 50 psi.
Oh, I crank them up to 65 when I take the monster onto the road.

It helps you see what area is losing air, so you can work it until it seats right.
On a slick climb with leaves and other loose debris the 5PSI really does make a noticeable difference. Sometimes, especially during out of the saddle climbing, the lower PSI is the difference between moving forward or spinning on wet leaves. I am not an expert rider but I can feel the difference.
On a road bike, at speed and in wet conditions, a 10% difference in pressure has a massive effect on grip and stability.
Road bike- 110psi, for training, 120 for racing
Kona Roast hardtail (single speed dirtjump/ds bike) 30psi with Stan's
Kona Stinky Dee-Lux (7" travel front, 6.5" BETD rear) 20-23 front and rear with Stan's, but adjust up or down by a couple pounds depending on conditions.
XC bike- 32 front-35 rear for training, 36 front and 36-38 rear depending on conditions.
I weigh 160 now, 155 racing weight.

xc w/tubes
56 psi in the damp mud and 58psi in the dry.
in the wet mud i use dh tires I do 50-60psi

All you guys who listed your road bike PSI - what tires? I run 23mm Vittoria Open Corsa at 130 max for temps under 65, 120 for temps over 65. I like a firm tire for speed...

What the hell do you use a Shock pump to pump them up?
Frame/Fork F/R Pressure (F/R Tires)
Scream/Super T 24/33 (Intense FRO 2.7/Mobster 2.5)
Isis/Z1 30/40 (Fire DH 2.3/Fire XC 2.1)
Scream/Super T 24/33 (Intense FRO 2.7/Mobster 2.5)
Isis/Z1 30/40 (Fire DH 2.3/Fire XC 2.1)
Giant AC - Tioga White Tiger 2.5 - started at 40 lbs and I keep lowering the pressure, they're around 34 right now.
Same bike with Michelin 2.5 - 37 for dirt, 45 for urban
K2 with Tioga DH 2.1 - 40 lbs
I can't stand when a tire starts to roll, I feel it right away and I hate it. I like my tires to keep their shape and be physically predictible. That makes me run higher pressures than most people do and I find traction through finesse.

I tried that once and quickly was slapped down with the obvious fact that I have none
MT Bike : 35 - 50 PSi , depending on the conditions , and How long it has been since I last pumped them up
road Bike : 140- 160 PSI
road Bike : 140- 160 PSI
40psi both ends in the XC hardtail (panaracer fire 2.1 rear, tioga DH2.1 front) 40 rear, 35 front on the rigid singlespeed
Somewhere between 15 and 35psi, depending on conditions, in michelin comp 16 and 24 on the DH bike.
100psi on the BMX, to make it roll fast and silently.

Tubulars. I'm too lazy.
If you flat on the road getting them past 90 is not easy - the pumps overheat or blow-off. At home I have a Planet Bike Ozone pump good for 160.

ss hartail with front squishy.
usually 40-45 in each but going with Stan's Notubes this year. I'll drop it down by a few..

Nothing finer than a muddy bike in the living room; pure bike whore class!
At least your bike doesn't get mad when you try to watch TV while messing around with it...
Nice Jericho man, saw it on a post on the MTBR SS BB earlier today... You'll love it with Stan's, you can climb sooo much better on a SS with lower pressure... I've had a couple of bad experiences with cutting tires in the last month so I've had to ride a few times with a tube in the rear, man I cant climb like that anymore, so used to the traction you get with low pressure, feel like all I do is spin out and bounce...
