You didnt do that at 30 mate.
Ive done it twice at 60, no air bags gone off, an the wheel hasnt even cracked, just ground alloy off on the kurb.
Also been in a car accident where brakes failed and we hit a roundabout at 70 an the wheel cracked an wasnt as damaged at that.
3 air bags off, cracked wheel i doubt it mate but if it makes you feel better.

Depending on the angle of impact and kerb, hitting one at 30mph could easily do that.
