P.S.I. question

I am a Newbie with a 36 spoke 20" Schwinn.
I weigh 170 lbs.
How much air pressure should I be using?
Tire is a 20" by 1.75" street type tread.
Tire states 40 psi maximum.
From my vantage point, it still looks kind of low as I ride..
.(yea, I know "looks don't count for much")

You should be able to safely put 60 psig in the tire. Tubes are cheap at
about 5 bucks if it blows. I run my 35 psig rated Coker tires at 50 psig
all the time. I run 20" freestyle tires at 60 psig. I weigh about 200
lbs but that really has no bearing on the safe pressure, just the tire
footprint.

Seems like it's a steel rim... the tube will po if you put alot of
pression in it.

Try it at 60, and if the tire feels too hard lower it. You probably
won't have a problem at 60, but people's preferences vary.

Fear is the mind-killer. Fear is the little-death that brings total
obliteration. I will face my fear. I will permit it to pass over me and
through me. And when it has gone past, I will turn the inner eye to see
its path. Where the fear has gone there will be nothing. Only I will
remain.
