if you are new to the list, the you should be made aware that there is a
searchable archive with Gerry and that tires have been discussed to death
every 4 weeks.  Please spare us another 10,000 posts re tires

You might try the Searchable Vanagon Archives located at:

http://gerry.vanagon.com/archives/vanagon.html

or

http://www.sason.com/vanagon.nsf

Or you could try searhing the archives via email.    See ftp://gerry.vanagon.com/pub/listserv/searching.txt for an
exhaustive description of how to search the archives via an email question.

Good Luck, Malcolm
