Last week I invented an errand to do in my 93 convertible. A mile from home I failed to avoid something in our beautiful MI road and the left rear tire blew. Could not believe that the previously untouched spare and the canister of compressed air had me up and running in 15 minutes. Made it to Belle Tire half hour before closing where they had my tire in stock. Is there anyone these days who refills the canisters? Now I have a cig lighter powered inflator on board. Feeling lucky.
