This has been mentioned recently. In a pinch, you could just file the stock arm a bit for clearance. It only needs 1/8", give or take, depending on the tire used, (which is hit or miss due to variations in manufacturing).
One idea that has come up is to make a Dark Side Prepared Kit, (DSPK) that would have a two piece tension arm that pivoted in the middle so that it would be more compact than the 9.5" long tension arm. The kit would have the arm with a pivot bolt and nylock nut attached, a zip tie for the brake line and perhaps shorter bolts w/nylock nuts for the ends. The idea being that it would be reasonably priced and small enough to toss under the seat or in your normal tool kit. I might even go so far as to stamp the correct CT size on the bar.
Think there would be interest in this?
As far as mounting, any tire shop with a modern rim clamp machine can mount the tire to the FJR's wheel. America's Tire, for example, didn't even flinch when they saw the wheel. I just said it was for a sidecar. Some shops will flinch due to liability, but I suspect if you're in small town no where, it's less of an issue. As noted before, they can't balance the tire, but that's less of an issue for emergency use. Especially for the rear.
@Galaxy Blue - Dude! I know you're not a little guy, but really, even you don't need fork lift tires. :blum:
