I am tenatively looking into buying a complete rear wheel setup for my WR to mount a paddle tire onto. We ride all over, and often ride dunes and forest in the same day. Another rear rim would definitely make things easier than riding the dunes on a knobby or trying to swap off a paddle. Any ideas? The stock Yam hub is about 90 bucks, but all the other parts start to get expensive in a hurry. Add in a rotor, sprocket, carriers, spokes, bearings, and it gets REALLY expensive. Like $600, which would be out of the league. Anybody have any ideas, or a rear rim setup that I can afford? I would consider an 18" rim from a scrapyard if this would work (I prefer not to sandblast excel rims), but I would need some help before ponying up. It is my understanding that the rear rim is a 2.15X18? Any help would be great. Thanks.
