Hi, my 50cc scoot is pretty new and it's Chinese.
and I keep checking my REAR tire air level and it is always low.
I put it to 30 psi and i check next day it is 25 and next day 20 and next day it is 15 and next day it is 10.
my front tire stays at 30 psi for like a month.
What could be a problem here?

The valve inside the stem may be loose. I had the same problem with a front tire. Turns out they never installed the valve core inside the stem tight enough and the tire would go flat on a weekly basis. Get a valve core tool at Walmart, 2 to 5 dollars, and check them. When I checked mine it took 1 1/2 turns to fully tighten it.

Probably the valve stem like gatekeeper mentioned.
Put me down as one that has had to replace a few valve stems because the rubber rots away.

why spend $5 on a special tool.
Don't some vale caps still have the grove in em to tighten the stem?
This is, assuming, of course, that you already checked for nails, etc in the tyre.

Cheap Chinese scooters are known to have cheap parts, valve stems are the same thing. Replace with some quality valve stems and don't worry for a long time.
