Hi,
  Serious question but also a word of warning if you are going to bid. 
 I believe that tyres have a shelf life  (I may be wrong) and can age if they are stored on or off a bike.  I know that when fitted tyres can age, walls crack, flat spots etc. 
 I'm watching a New Mich' Pilot Race 180 back tyre that is currently at £16 plus P+P. 
 As a last minute thought I asked the seller how old the tyre was ...... answer - made in April 2000 

  I know the tyre is new and un-used but in my mind it's "out of date". 
 Would you agree or am I being over cautious.
