Tire pressure

[Narcoleptic Insomniac]

As I'm sure many of you I grew up riding 1.85"-2.00" tires pumped up to 90psi. In part to avoid getting pinch flats after casing a ledge and in part because that was just how you'd set up your bike back then. Then when tires started getting wider I was running the same pressure as before on the new larger tires and didn't think much of it. It wasn't until I started riding big bikes that I realized how the relation between tire width and tire pressure works. Since then I've been gradually running lower pressure on my BMX and don't see myself running rock hard tires other than for a concrete bowl session or something along those lines.

I now run 35-40 psi in the front and 45-50 psi in the back on 2.3" and 2.2" tires respectively. This is really low compared to what I used to run years ago but I've found the bike feels and handles best at this pressure and my wrists definitely agree.

What's your tire pressure of choice?

Riding flatland these days I'm on khe tires that are 1.9 i think. 100 psi front and rear.

When i rode ramps it was more like 70ish

[CMB]

I generally keep it around 60 psi or so now that I'm running bigger tires (2.4,2.25). I tried 90 psi for a hot second but it felt terrible and my wrists were screaming.

That's what I was running for the longest time before trying lower pressure. It also depends on how heavy you are.

For flatland obviously harder is better.

80psi 2.15 front and back. I'm heavy so there's an issue there. Also, low pressure wallrides suck.

140 psi on primo comet 1.5" tires. I ride flatland tho 👌👌😃😃

[JFax]

I ride bowl and vert. Get really paranoid when the tyre start to give so I ride 100+ PSI in my 2.3"

[O.G. David]

~45 front and ~55 rear whatever i ride

[dude...]

2.25 in the front and 2.1 in the back, i usually pump them up to 55-60 psi then just leave them til they drop to 40/feel shit and sluggish for manuals. when i started out riding i used to run 35-40 in like 1.85-1.95s hah

Same here, though I usually start with 80 and don't mess with them till they get to around 50.
I'm riding the new style Aaron Ross tires and they are great--they old style suck. Unless I kept them at at least 80, it always felt like the sidewalls were folding over.

100 psi front and rear. It makes a huge difference if you ride ramps at 50-60 psi then pump them up to 100. Much faster and you don't get the horrible tyre flex when carving around.

[Sasha]

I always used to run 110 in 2.1 or 2.25 front and 1.85 rear. Now I have 60 in 2.25 both ends. Feels way better.

Why do the flatlanders prefer such small widths? For me the bigger the tire the easier it is to carve around on one wheel.

[blueee]

under 50psi is great if you ride slow


say im riding a 2.25, 2.0 both at 75psi at sea level, 100degrees. how much is tire pressure affected if i then go to 5000ft elevation 40deg F? is the dial on the bicycle also effected?
