[T3] Tire failure?

[Dennis Stiefel]

I have been working in one way or another in the automotive repair field 
most of my life. But this is something I don't have a whole lot of 
experience with this. All I can say is I know some reputable shops in my 
area that has these compressors and they and a few of there customers 
have had good experience with them. I was just commiserating using this 
on my Fastback since I won't be putting a whole lot of miles on it at 
any giving time just from a dry rotting prospective. If it don't work 
I'm just out $10 bucks to have them filled the first time then its free 
after that.
