Another psi question

Based on your weight, rim size, tire width, tire depth, tire/tube

proportionally if you put on heavier shoes, you just ate a macho
burrito, or your shirt is wet.



should I assume this a joke?

Also, I say I'm at 17 but one psi reader says 18, another says 17

That is not a joke...
You should just go with whatever. I run my psi low, I bottemed out
jumping up a parking block and then 3spning off... I will raise my psi a
little but i will still probably bottem out when doing certain stuff
like 180ing sets, tiregrabing sets, ect

Just rotate your cranks often.

If you ask for precision and you get precision don't assume it's a
joke. If you realize that you're asking for far more precision than you
need then you can start leaning toward the joke side. Nice photo, by the
way.

There's no difference between 17 and 19 PSI.


Forget the tire gauge, just pump it up until it's too hard, then ride
it and let a little out at a time until it gets where you want it.
Run it a little higher though so you don't bottom out. You'll get used
to hopping with it.

the reason I like 17 psi is because when I static jump SIF (which is
what I usually do) I can jump really high. When my psi was high, I could
go months without breaking/tying my record. After I went with 17 psi, I
hit twice in 10 minutes.

I'd like to run at a high psi because I know I'll get a lot higher in
the future. But I just can't static jump SIF with a high psi. I'm
thinking its because I can't get a big compression, do you guys have any
tips on compression and static jumping.

compression doesn't really do anything for you except allow your timing
to be off more and get a little bit better hop.
my tire rarely falls under 25psi, and it seems like i'm starting to
edge towards 30 psi now, and i mostly do trials, there isn't much for my
favorite style (which usually requires more air in the tire than i like
for trials)

I see many people riding at mid 20's. But most of the people are a lot
bigger than me. Taking into consideration that I'm only 100 lbs, what
would you think I should run at.

BTW thanks for your answer Harper, it's helping.

I think you need to go out and ride at what psi you like most, you are
getting more worried about your psi than your ride
