Bet that would be an issue ! and you are correct to expect some response from them...
I've always said, things DO go wrong, and how a person/company responds tells you more about the company than the issue itself.
but for many owners spare tires are a luxury - I couldn't imagine where I would store a 22.5 inch tire and wheel, much less pull it out and try to mount it myself
That $150 a year roadside assistance sounds purty good to me in those instances... good luck to you...
