Robot tire sources
Hey guys,
Are there any good suggestions on suppliers for robot tires minus the wheels? I am planning to generate my own AL wheels as I am starting to see that the weight is a bit much now for those thin Pololu wheels as was predicted. Since the bolt pattern is set in the pulley I will just go ahead and make the new ones but I'd like to find some tires that have a similar outside diameter 3.5"
I find lots of wheels with the tire molded on but not a lot of just tires.

The old Chi Bot and even the Scribbler and S2 use "O" rings in a groove. Might work for you and they are available in all sorts of sizes.
I you are looking for real tires, Wheel chair and scooter tires might be a direction.

If possible I want just the tire and not the wheel/hub/rim whatever you want to call it. These are actually just about perfect and I can just rip the tire off and make a new wheel for it to ride on.
ETA: Kids scooter wheels look like a possible source as well.
Vendor says they are rubber. I'm going to give these a shot and if they dont work then option 2 will be kid's scooter wheels.

Have you looked at BrickLink for Lego parts?
I think this page has the same wheel.

I have lots of Lego wheels myself. I think this particular one is pretty hard rubber.
In general Lego parts are good quality but many of their wheels are made more for show than for heavy duty use.
Thanks for link to the cheap source! I was thinking of experimenting with foam filling in the tires and that's cheap enough to buy a spare set to play around with.

Seem like a decent source for bigger, heavier wheels.
U will have to modify the hub.
