What Is the Problem With Lead Wheel Balancing?
Lead wheel weights are used worldwide to balance vehicle tires. An estimated 64 million kg/year (70,000 ton/year) of lead is used worldwide in the manufacture of wheel weights. Automobile and light truck wheel weights vary in size and weight, ranging between 5-150 mm (0.2-6 in) in length and 7-113 grams (0.25-4oz) in weight. A typical vehicle contains between 200 and 250 grams of lead in wheel weights. This amounts to 10-12.5% of vehicle lead use, excluding the lead-acid battery. Recent studies have shown that lead deposition from lead wheel weights is a significant and previously not quantified source of lead being releases to the environment. The majority of wheel weights currently in use are clip-on types that are attached at the edge (horn) of a wheel's rim; however some new aluminum rims require adhesive weights due to their shape.
An average vehicle contains ten wheel weights (two on each of the four wheels and two more on the spare).
Although some effort is made to collect and recycle these weights at the end of a vehicle's life, most of them are overlooked and often end up in the environment or as contaminants in the metal recycling process. A disturbingly large number fall off onto the road during vehicle use. In October of 2000, Dr. Robert A. Root (Environmental Health Perspectives, Volume 108, Number 10. October 2000) published a study documenting the rates at which these weights fall off their host vehicles and are gradually abraded into lead dust. His study was the first to examine this phenomenon, and it established that lead wheel weights are, in his words, "a major source of lead exposure that heretofore has not been recognized." The Ecology Center surveyed a one-mile stretch of urban roadway in Ann Arbor in 2002 and recorded very similar lead deposition rates
Guide for correct appilcation of adhesive weights
1. Clean the rims with an appropriate cleanser (e.g. 70% isopropanol) to avoid grease and silicone residues on the rim.Ensure that the temperature of weight, rim and ambient is not lower than 16℃.
2. After clean the rim, it is necessary to verify that the
3. Remove the protetive film of the weight,and put the
4. Press from the center towards the two ends after placing the weights. The adherence force reaches 80-90% after about 24 hours, In 72 hours, the adherence force reaches 100%.
