Change tire config on the fly as a powerup/upgrade

Hi I would like to be able to switch tire configs via a pickup for a powerup/to access certain areas of a race track. I have created two tire configs which simply have different friction scales, and would like the tire config to point at a variable for the type of tire. I have looked around but it seems that this issue was never really resolved, I have looked for the error report UE-27020 on

but it seems this was never addressed in blueprint. Any ideas or alternative solutions would be greatly appreciated.
