That is your opinion, I have mine, all it does is center the wheel, it does not hold the wheel on or in any way effect the strength of it. Being tapered lugs they are definetly lug centric, my buddy has a dually it is definetly hub centric as it does not have tappered lugs, the SRW trucks may be both but if you are using aftermarket wheels you either need them to be lug centric or get hub centric wheels and different lug nuts, you only need one. The wheels are held on by the lug nuts and the clamping force of eight lugs at 135 ft/lbs of torque.
