[ausev] EV tires

[Derek Bridges]

    The online Greenseal report on LRR tires that Brian mentioned has 
several pages of material on of LRR background and test methodology and 
it culminates in a scatter graph of test results without anywhere 
mentioning specific brands and models of tires.  It includes a URL to a 
55 page report from the California Energy Commission that again avoids 
mention of specific brands and models. The Greenseal report does say 
that manufacturers sometimes publish artificially poor LRR numbers on 
their cheap tires to make their expensive tires look better.
    Brian, where did you get the numbers that led you to choose the 
Sumitomo tire?  What easy-[for lazy people]-to-find information 
resources are out there?
