FYI...I recently ordered 6 tires and 2 chains from planet cyclery.com. The box showed up with only 2 tires. After about 50 emails most of which do not get responded to they have not provided either a product or my $330 dollars back. I am attempting a chargeback but their bank is now providing problems. It appears they have a decent feedback on amazon and ebay so I am not sure if it is just me but I have been ripped off. buyer beware as I bought directly through their web site. There is no phone number and they are unlisted.
