Cluster, tires are expensive only if you let them be. I looked everywhere before buying, internet, stores, tire dealers, etc...
I found my tires (33x12.50x15 GoodYear DuraTrac) on TreadDepot.com for $168 (cheapest around anywhere I've found) so I went tot he local GoodYear dealer in downtown Pittsburgh, told them the price I found and asked if they could do any better so they gave them to me for $146 a tire.
I went down to 15" rims because everyone is using 285/75/16's to stick with the stock 16" wheels and alot of tires in that size are on back order and over priced.
I spent less on a set of five 15" wheels and tires (33x12.50x15 on 15x8)then I would've spent on four 16" tires (285/75/16).
