How to set walls and objects collisions?

Hi, I'm relatively new to the use of RTB. Since all of my tracks are missing of collisions for every object/string object, how can I make them "not trepassable"? And how can I make the tyre wall "physics"? I saw a kart track made on RTB with a full crushable tyre wall. Thanks for helping

in walls you have as first object a yellow "do not cross" panel, wich is used to give collision. you can enable your object collision in the properties tab on the right, but since it's a very heavy process for the PC the higher poly your model has, the yellow wall is way to go. If you're working for AC be sure to not tick the double-sided box on wall properties panel

Understood, thanks. Does it works the same for tyre walls? I want to have them acting like a real pile of tyres as I have seen on other tracks...
