Continental Tire & Wheel This company is not in business.
Please call B&W Wheel in Fontana, CA (909) 356-8094
A machined shank is screwed onto the existing wheel studs. This
method seems stronger than others I have seen.
An aluminum spacer slides over the shanks leaving a new set of studs
exposed.
Checking the lug nuts occasionally is all that is necessary to insure that
your adapters and wheels are safely secured with the Continental Tire & Wheel
adapters.
