Re: Cheap vacuum pump

Jonathan, all,

Agree with you there, though not fully for the same reason.
Tires are generally made of oil-resistant neoprene rubber
so I don't think the oil would be the biggest issue here. How-
ever, fridge compressors are designed to pump relatively
high pressure but not too much in the way of volume. I'm
not too sure what the CFM volume rating is on a typical
refridge compressor but I'm guessing that it would take a
WHILE to inflate a fully deflated 35 PSI rated 16Rx255 tire
on the rim. May be ok for inflating touring bicycle tires, but
probably not for most motor vehicle tires. ;^/

I'm not sure if it is a good idea to inflate car tires with a fridge
compressor. The two I have played with as vacuum pumps blew some oil out the
exhaust, and oil in your tires ain't good.
