Think it's a better idea to try to stop at kerb side asap but
carefully and even goin to the nearest petrol kiosk in sight might
cause more stress on your rim and in due cause more damage to your
vehicle. Try to change the type it you could manage or join the
Automobile Association of Singapore, they could assist you. Juz a
reminder always try to pump your spare tyre when u r at the petrol
kiosk if u r doing it for the other tyres, a flat spare is as good
as nothin'
