Kibblewhite Precision Machining, Inc.

Spin True lead-free wheel weights

California based Kibblewhite Precision Machining, Inc. (KPMI) has developed what it describes as “a true lead-free spoke wheel weight that won’t come loose.”

Designed and machined in-house at Kibblewhite’s Pacifica facility, they are made from chrome plated stainless steel, with prototypes machined and then tested on a full range of wheel sizes. “At no time during any of our testing did a wheel weight come loose. Spin True wheel weights were designed to cover ranges of nipple sizes.  The two most popular nipple size ranges were developed with six variations in weight, spanning 0.25oz to 1.5oz. 
They fit nipple diameters from 0.250” to .350” and are “tough, corrosion resistant and attractive. The patent pending design features symmetrical halves that bolt together and lock onto the nipple.

The United States Environmental Protection Agency (EPA) states that the reason for the ban on lead wheel weights is that they fall off of wheels, get ground up in passing traffic, and the lead then enters and contaminates ground water, lakes and streams when it rains. 
At least seven US states have already instituted a ban, with more sure to follow soon.  The EU banned the use of lead in wheel weights more than 10 years ago.
