new DC2's and balance

ive got a new set of dc2's on my truck and when the dealer balanced them they used an adapter on the hub hole instead of a adapter on the lug holes.was this the correct way to do this?

 

Anyone???

 

thats how its usually done around here in fl

 

you can...

-put a cone in the center on the back with a rubber/plastic cup screwing on against the front (machine, cone, rim, rubber/plastic, handle)

-have the inside of rim sit against the balancer with cone through hub hole and the holder against that (machine, rim, cone, handle)

-have cone on the inside and use an adapter that pushes in on the stud holes. (machine, cone, rim, adaptor, handle)

hope that makes sense... I prefer to use the 2nd one on most rims, least amount of variables i guess
