My brother weight almost 210 lbs and he tried to sit on my trainee 24-inch
unicycle (for adult version that I bought, but the tire was very squishy in
such a way that the rim almost touch the ground. The tire pressure is high
as it can go, which is 35 PSI.
Any suggestions? Maybe he needs a different tire or something?
The simple answer is when your brother rides your uni, add more air into your tire, like up to 70 lbs, double what you have now. Most people in our club overinflate their tires, with the exceptional few who underinflate specifically for MUni.
If you read the side of your tire the range of tire pressure is usually 35-60 lbs. You’re probably at the bottom end of the tire pressure scale.
If you’re not in the 200 lb weight range and you ride your uni with 70 lbs in your tire, your butt will really hurt you when you go over a bump, so deflate your tire if you’re without your brother.
You could also buy a new tire that has a higher pressure range. Here are some uni tires:

Most unicycle riders run their tyre above the rated pressure. Try 45 -
50 psi.

you don’t need to worry about too much air in the tire (within reason) as long as the tire is seated on the rim well. check along the rim and make shure the tire is in the same amount all along the rim and then fill it up. most the time I have about a 100 psi in my 20". I think it’s easer to ride with the tire full and I can go faster when I play hockey.

I can relate to this one. I’m about 240 and have run into the same problems
as you, in addition to a bent rim and broken spoke on one of my unis. I never
did any big drops, just curbs and occasional hopping about 2-3" in the air.
My first tire on my 20" was only rated to 45psi or so but I overinflated it
quite a bit and it held, but I did get a slightly wider tire (20x1.95 I think)
that was rated to 65psi, and I inflate that to 75 without any problems. The
original chrome steel rim on this one did get bent pretty badly from a tube
exploding just right, and I replaced it with a Sun Rhyno Lite aluminum rim.
the Sun rim has held up really well so far, and I’ve done drops off curbs and
minor hopping with it.
My first tire on my 26" (the one with the broken spoke and bent rim) was a
Kenda 2.125" wide tire, rated to 45psi. I pumped it up to about 65-70 lbs, and
it worked, but developed a nasty bulge in the sidewall. I then bought an IRC
Metro Duro tire from unicycle.com. The one I got was a 1.5" wide, rated to
100psi, and it’s worked great with 80-90 psi in it. That tire in 2.0" wide
might be better, possibly allowing lower psi and more sidewall flex. Should
help with the ride quality a bit.
