Where are you located?  I have a set of 4 pirellis that were on my 56 sunliner for about 3k miles or so before I got the coker WWs.  THey have been in teh attic for about 4 years, covered and clean.  If interested, maybe we could work something out?

you can email me at rongrove(at) comcast (dot) com if you are interested....

Thanks!
