It is not the official way to remove a runflat tire but it works! What do you need?
– two forklifts
– long iron bar
– some wood bloks
– a lot off grease or soap
Put a tire under the forlift (picture 1) and put a rope around the runflat tire(picture2).
Grease the tire and runflat good!(picture 3 and 4). Then pull the runflat and make tension on it (picture 5) with the forklift. Then put on the wood and wig it with a ironbar(picture 6). Put a gentle tension on it and now the runflat will slowly come out!(picture 7)
