Riding low PSI

So I ride colony griplock tires, and the max PSI is 110, and I usually ride around 50-60 but whenever I go to a lower psi, the tire comes off the rim in certain spots, and the tube pushes out. Does anyone know how I can stop this from happening so I can ride lower PSI

Certain spots of the tyre? Or rim? If you've had a blow out you may have damaged the bead of the tyre, or flared the rim

Try running 70-80, usually high inflation tires have a minimum around that psi. You’ll get a pinch flat for running it too low anyways.

I ride street, 50 odd psi, plenty of bump jumps all day long. Haven't had a pinch flat for years and years

Same. I just ride 60 in the back to just to have my manual speed be faster and not slow down too fast... but I've got 50 psi in the front..

I don't crash, I do random gravity checks...

How much do you weigh though? I can’t run any lower than 80 on my tires without a pinch on bumps, but I weigh around 250 pounds (estimated around 116 kg off the top of my head give or take).
I’m not even fat, I just have dense muscle structure.

I weigh like 130, so 60 and 50 work good for me...

I hop into stairsets like a flatbank and ride up stairs if they have 45 degree edges. I also case stuff lol

I run 60psi in my 110psi rated tires.

Sounds like you're bead is damaged. I've gone down from 100psi to 70 on slightly bigger tyres. Feels so much better! Any less and flowing around bowls feels sketchy imo.

I'm 83kg, recently lost about 5kg. I literally bump jump every curb I ride past when going from spot to spot, and do a lot of bump jump to wall rides etc.

That’s still miles below what I weigh lol. Only thing that keeps my hops high is just muscle, weight is definitely not on my side, then again, I don’t have it bad as This Radical dude
