Hey Pete!

I just replaced the tires on my Mav. Same method, except I didn't bother with heating the tires, and used WD-40 as the lubricant. Didn't even break a sweat.

Make sure the tire is seated properly. Place it on an axle and spin it to ensure this is the case. To do the screws, I used a #57 drill in the drill press, after making sure the tray was exactly 90 degrees to the drill. Drill down through the threaded side. Push the screws in from the non-threaded side. Tighten. Done.

See you in the spring!
