How Much Psi In Tires?

[BmxStreetz]

ok im 5'11 190pounds and when i jump spine today i hit my rims i got 45 psi in my tires no but what should i have?

[I_Suck_At_BMX]

I put mine up to about 95 PSI and then dont fill them for ages. I like them at a point between soft and rock solid. At a point where its really hard to make your rim hit, but soft enough where it doesnt feel like my tires are made of steel when i land. I dont know if this makes any sence. I dont know how else to explain it.

The tire's sidewall should say.

More pressure for Skateparks and street (80-110PSI)
Less for dirt and trails especially if wet...(35-80PSI)
At least thats what i do, but i like having alot of air in my tires...

93.8176. No more, no less.

jeez, i only pump mine to 50 psi and i do street and park stuff, can the innertubes handle it?

[JohnBoy]

WOW!!! 110psi Even 80 is pushin it. Most average size 20'' x 1.75" are between 40 and 60 psi. With your weight I'd add another 10 psi and see where you're at.

Um, hello...

Well i suppose im not good enough, i only inflate them 93.815

[bmxdumbass]

i have mine at like 65 or something

[wethepeople]

Um, hello...

My tire says 35-55, if I have it less then 55 I'll flat on tricks like abubaca's.

Run your tires at max, as indicated on the side of the tire. There is no functional reason to run them any less. Rolling resistance increases, handling decreases.

Running tires rated for higher pressure increases your ability to pivot and typically decreases the likelihood of a pinch flat or dinging up your rims if you case. Traction is decreased marginally.

Overinflating tires is usually okay for a couple psi...as a general rule, max pressure is determined by inflating the tire until it blows off the rim and then dividing in half. So if the max pressure on the side of the tire reads 65, the tire is likely to blow off the rim at about 130. HOWEVER, whenever you hit something, tire pressure increases momentarily. So the closer you are to blowing the bead off the rim, the smaller the impact required to finish it off.

Yeah. I agree.
