would someone explain to me why it is so difficult to get a flat fixed on a tire w/ only 500 miles on it , & a small puncture hole in it? I went to my local tire shop yesterday only to be told they could only replace the tire & not repair & put a tube in it,due to "liabilty reasons" I have been doing this for years (on mags) & never had a problem w/ a tire. Needless to say,I thought he was trying to bend me over & left! Finally I found a guy who would throw a tube in it but would still not patch the tire from the inside. Any body had similar experiences?
