Where to get solid tires?

I have seen a couple pictures on here of robots that seem to have solid direct replacement tires for the 12.5" pneumatic ones in the kit. Where would a person get these? Thanks.

fill your pneumatic tires with something (i know this sounds ghetto and like a joke, but i’m dead serious)

when you are looking for solid tires are you looking so there is no chance of poping a tire or are you looking to reduce the “bounce” factor?

if it is because of poping you can get some stuff called slime.(from any bike shop) and it will prevent flats.

and for the bounce problem i would call skyway wheels (the supplier from the kit) and see what they have…

just a side question…are wheels considered raw materials as long as they arn’t modified so you can buy and bring to the comp?
