It is looking like I have to buy a couple of tires for my 2002 Ford Focus ZTS and I have been pretty naive when it comes to buying tires in the past and am looking to learn/save some money. Provided the flat can't be patched - Do you recommend tirerack.com to save some money on tires? If so, what are the brands to watch out for or to buy? This is a summer car only, so I'm not necessarily needing anything for the snow here in Wisconsin. It seems as though buying tires locally is a lot more expensive than some of the tire prices I've seen there.

Thanks for your help!
