Tire pricing has gotten ridiculous, but it also has to do with the tires being better made as well. My favorite tire when you can get them, and they are high, are Hancook DyanPro AT/ATM's. They look great and they are the ONLY tires that have EVER made it through a Christmas tree hauling season without having to be changed immediately after the season was done. When I first bought them, they were than most others, but the next time I needed to change them I couldn't get them, the price had gone up to $230 EACH and were on national back order with a projected availability in THREE months...lol
To answer the OP's question, about the best place to order tires "online" would be tirerack.com. But depending on what you want, we may be able to help. We offer SOME rims, tires, etc.
