I have a 2002 Accord Sedan LX, I recently bought it not to long ago, and it has 2,100 miles on it.. today I was going down the highway and I got a flat.. didnt know it for awhile till someone told me and I rode on it after heard noises so I stopped, and put the donut tire on..

I took it into a mechanics shop and they said since it looks like its been riden on they can't fix it..and I might need to buy a new tire, but I'm wondering would something like this be covered under warranty cause it's expensive to get a damn new tire..
