Wheels from Jegs...free shipping. Cragers are about 35 bucks each so your under 150 bucks for wheels.
Tires...id go with Kuhmo or BFG MT's...the Kuhmos are a good bit cheaper and dont give up much or anything in the way of performance to the BFG's. Most places have them for about 100-115 per tire...figure in probably another 15-20 per tire to ship them...so probably around 500 bucks putting you at 650 for everything. Thats how i plan to go when it comes time to upgrade this spring.
