I have succesfully used the tyre pliers to remove a tyre from a D2 rim. I did however mark the rim a bit.
I have even broken the bead while the tyre and rim were still on the vehicle using the tyre pliers to clear mud from between the rim and the tyres rim protector.
Just a thought - could you use a small piece of rubber against the rim to protect it as you lever the tyre off?
