I bought 5 new tyres for my 300 Tdi project vehicle, but the tyre shop was unable to balance the wheels as the centres in the Dynamic rims (which were on the vehicle when I bought it) are about 1/2 an inch wider than the standard Defender rim and they didn't fit their balancing machine.
This photo is with the Dynamic rim on the 300 Tdi.

and the second is my Td5 on standard rims (they are both running heavy duty axles and hubs) and it is quite clear the Dynamic's are bigger.

The guy at the place said that 90% of tyre fitting places would not have the larger attachment to enable balancing these.. This surprised me as was the fact he didn't have the attachment as this was a large and busy tyre business with lots of 4WD's coming and going.
However driving the 40kms home after the fitting with unbalance wheels, all seemed fine though I would certainly like to get them balanced.
