MowDidley,
I like your method for changing tires by using a bolt through the wheel and then mounting it in a vice - this stabilizes the wheel when prying the tire off or on. I'll be sure to do the same the next time I change a tire.
By-the-way, I recently obtained an HRC215K1 SXA, and I also have the HRC215K1/HRC216K1 shop manual, which says to use adhesive when mounting a new tire. After looking at the manual more closely, this statement about adhesive was only used for the HRC215 (which shows a plastic wheel in the HRC215 pic), but it said nothing about tire mounting for the HRC216 (which shows a steel wheel in the HRC216 pic). I guess this means that adhesive should be used with plastic wheels, but it's unclear if that's the case with steel wheels.
