No, I don't have an air drier, I have thought about getting one of the inline cartridge style ones though. I only run the compressor just before I use it and drain it about every other time or so. Never get any moisture out the drain.
On the Dyna Beads they do recommend not getting moisture inside the tires, It can cause clumping of the beads. When I mount tubeless tires I make sure the tire and wheel are dry and mount them dry, no lube. On tubed tires A bit of lube won't hurt, it can't get inside the tube.
I only put air in my tires at home. This way I have a fairly good idea of how much moisture gets in the tire. At most any gas station you never know. A garage may have dryer air.
I agree with 5twins on using something up off the floor and solid for tires. I used to work on the ground, but as I age getting down on the ground isn't much fun.
I have Harbor Freights manual tire changer for car tires, I also got the bike tire adapter.
I don't use the over head arm that comes with it. I just lever tires on/off. Having the tires up about stomach level so I can stand up to work on them is so much better than on the ground.
I was up looking at them just the other day. They have made some changes to the bike tire adapter. The part that sticks up to grip the wheel is much taller than mine. I have thought about making mine taller, on the Harley rear wheel I have to remove the belt pulley so it the hooks can reach the wheel.
Longer hooks would save that much work.
I also added extra holes where the hooks slide on the arms, I can do the 8 inch trailer tires too.
Oh one more thing about the beads, you can take them out of the old tube/tire and put them in the new. I'm on the third set of tires for the Harley on one set of beads.
