Versahaul make a high quality carrier that should work well for the TW. The side walls of the carrier rail are angled outward to accommodate wider tires. It is very heavy duty and expensive compared to many other carriers, but is well built and has some nice features like retractable tie down points, etc.
Several riders, both here and on ExPo Forum, myself included, have been using an "Ultmate MX Hauler". Slips into a standard receiver and uses a small bottle jack to lift a platform under your engine [best if you beef up the stock skid plate]. I like mine very much, loading and unloading my TW several times a week. Prefer to drive my bike to the dirt rather than ride pavement very much.
