1602.0. "Flat tire" by UNYEM::BLUMJ () Mon May 23 1994 12:38

    I have recently installed a Dubro 3" wheel on my glider.  The assembled
    glider has been setting all week on my basement work bench. There is
    a huge flat spot on the tire which does not allow the wheel to 
    spin truly.
    
    Is this an anomaly specific to Dubro, or do all brands do this?
    
    Thanks,

Jim - some do, some don't.
I always had to store my Aeromaster on little blocks to keep the tires
from holding the weight and deforming.

I have had more bad luck from foam tires than the hard rubber but
to some extent they all do it.  Thanks for reminding me of this I
wanna put some blocks under landing tonight to avoid the problem.

1602.2Foam Wheels Will Flat SpotLEDS::WATTMon May 23 1994 13:326
    All of the foam tires will flat spot if left sitting under load.  I
    never really noticed this with Dubro wheels though.  Best bet is to not
    leave your model sitting on the tires, especially in a hot car.

1602.3Just pump it upMINNY::MUELLERAMon May 23 1994 18:237
    Try to pump the tire. It's easy. Puncture the tire with a needle and
    stick the tire into the deep freezer for some time (24 h). After taking
    out the tire seal the hole with some super-glue - and wait until the
    tire warms up. The cold air in it will warm up and the tire sould be
    inflated (due to the expansion of the trapped air).
