Why to not side load the motor? You will likely destroy it. The bearings will not last as long, break and then your motor will burn out. You could also bend the shaft of it or something else can happen

You are right but in 2013 we made a full court Frisbee shooter by mounting a 8mm hub to a cim and a 8" Andymark pneumatic and it survives to this day after several hours of running time since 2013 (we didn't know better). You really shouldn't do it if you can avoid it however and this is such a case.

Beware of using the pneumatic wheel at high RPM. I still remember how that max RPM warning showed up on the Andymark product page midway through the 2013 season. The primary problem was balancing it. The inlet port for air needs to be offset buy something on the other side. Also if you want to save money it's a less optimal choice. I would think andymark 6" or 8" rubber treaded wheels would do fine here and cost less.

Edit: What tools do you have access to? That can change a lot of things.
