So how hard presure should be in my tire? Im gona try to learn jumping.
Is there any differences between TRIAL tyre and ordinary one?
As much pressure as it takes your hands to use the mouse and keyboard to search and obtain the required data without starting another thread when there is an abundance of info on such a topic on the forums already.
i’m sure the search function can bring up thousands of posts just like yours as well, so why don’t you use the search to find those since you are so accustomed to it.
ordinary tires should be hard… usually a few psi shy of max recommended… i have one that says 30psi and another that says 120psi (i fill it up to 60 or so, that’s plenty for it to be rock hard…
trials tires… soft, but not too soft(you don’t want the rim banging on things)… don’t ask specifics, or even more specific ranges, nobody but yourself can decide that one… but i will tell you it will be 15-30 PSI for a trials tire… and if thats what you are looking for, change it and figure out what you like, don’t let ppl influence that one.
Short answer:
Enough to keep your rim off the ground
Detailed answer:
Basically, enough to keep your rim off the ground.
Notes:
There are no numbers for this, because it depends on your weight, tire size and width, and other factors. So just keep your rim off the ground and you’re fine.
Yeah, but he would have to use the search to do that. 
Sorry for the mixed metaphor, but it should be as hard as a rope.
well… here’s your search, i went ahead and went through the effort in case you didn’t search function
None of those search links work.
For trials, I adjust my PSI to get a good bounce out of my tire when I jump but still enough to keep the rim from bottoming out. Mess around with it.
Well it works here when i click on mine.
I got your point! Besides I did use the search, I didnt use more that 2-5 minutes to that, but I did use the search.
Thanks, for all those who answered to my question.
