I know these are old posts.......but I work at Costo in Salem, We deal in Michelin and BFG. Never forget about Costco if thinking of BFG's. Most warehouses however can only install stock sizes, as in whats posted on your door placard! But you can either bring in a set of wheels, or just buy the tire and have another place install them. Either way the tires are a HECK of alot cheaper than other retailers..... We can even get the new BFG Mud Terrain K/M2's! Our sizes (things that will fit the stock or lightly moded K/J's) won't be released untill Phase 2 of production (2008) though, and aren't too much more than the K/M's
If you have any questions please feel free to ask!
I still work there so if you want prices let me know the size and load rating you want and I can get you then installed and carry our prices!
Nice thing is that the prices are the same where ever you go, and you still get all the warranty's, they just can't work on the Jeep if the tires are oversized.
Anyhow.....Hope that helps!!!
