rear wheel always flat

Ok I weigh 240 lb BUT I see people much heavier than me
riding around and their rear tire isn't as flat as mine. I
made sure it was fully inflated before the Chicago bike
the drive this morning BUT it still was flat. Other than
my weight is there any other reason?

There are a few variables/posibilities to consider:

What pressure are you running?

What width is the tire?

Is the inner tube definitely good (no slow puncture/leaky
valve)? Dip test it, or swap it to be sure..

Are you definitely not just imagining it?

I assure you, there is no such thing as algebra.

Dude.......The pressure on the side is more of a guideline.
Run enough to get your rim off the trail. Or purchase some
higer air volume tires. A 2.3 or 2.5 for a big guy is a
good thing.

Sheeesh....

Hey Mark

no clue as to pressure but the tire is rock solid. Tire
is 2.0 wide I put in a new tube before the ride AND dip
tested it. No my @#cking friends photographed it :-)

Should be at least 40lbs pressure or more at your weight. Do
you have a rubber liner to protect the tube from the spoke
nuts? Hvae you checked the inside of the rim and the spoke
nuts for burrs? Have you checked the tire for something
sharp sticking thru it? Have you inserted the tube carefully
so it doesn't pinch when its inflated, have you replaced the
tube lately? Have you tightened the valve? Is the valve
clean and protected by a cap when you're riding? I don't
believe in messing around with tubes. On the trail I will
patch them (I don't like carrying extra tubes around just in
case). But when I get home I replace them.

There's always a reason, you have to be a detective.

You might want to mention what tubes, tire and rims
you're running. Some wheels are more prone to pinch flats
than others.

BTW, are you actually getting holes in your tubes or is the
air just leaching out? There are two different types of
materials (mainly) used to manf inner tubes. One of them is
known to leak air (naturally) more than the other.

I forget which is which, but I have some tubes in one of my
bikes that usually needs a little air after a ride depending
how hard I ride, but it doesn't have any holes.
