I usually start with consumer reports and then look at the online reviews before I decide. I have had good luck with that approach so far. I need to start that very thing here shortly as my shoes have about had it. I am waiting on the chance someone will sell me their LTZ rims first though. :wink:
EDIT: I now have my LTZ rims and some Conti Pure Contacts!
