A while back...Last Summer there was a theread about the new leak
proof innertubes for aircraft tires. (I've forgottten the name), but
at any rate I wanted to add that I've had them on the mains since last
spring and still haven't had to pump them up except once about a month
after the instalation of the new tires. It's a long way from every
two weeks.
