Default mounting things on axles and two piece hubs

I am totally new to karts and machines in general. I have started get the idea but I am still confused about a few things.

How do tires on split hubs work? How do the tires hold air? Where does the nub that you fill with air go? How do I know what size rubber tires to get for rims like these?


I understand key ways or key stock (how ever one refers to it not sure) are used to keep hubs from spinning on an axle but how do you keep everything (sprocket hub, brake rotor hub) from sliding laterally along the axle?

Lastly how do hubs mount to spindles like these and a live axle like this? Basically, what keeps the hubs from shifting back and forth along the bolts and ends of an axle?



Thanks I appreciate the help

I will tell you that spilt rims need innertubes, I'll let someone else answer the other things.

I believe split rims use innertubes along with rubber tires.

To keep all your parts from sliding laterally on the axle, all your hubs have set screws that tighten down to the axle. Or sometimes you need to use a Collar that will lock it down.

To keep the things in place, setscrews are used. Also, spacers between rims and bearings can be used to keep the axle from sliding. Generally hubs are held on by either a bolt at the end of the axle, and spacers on the other side, or set screws (which i personally wouldnt trust).

Wow, thanks for the fast replies. Ok I get the idea now. So you just put spacers behind the wheel hub on the axles. What about nylon spacers and metal spacers? do you need both or is there an order?
