Wheel Weights
Lead and zinc alloy wheel balancing weights from tyre fitting operations, a consistent, high-volume scrap grade from the UK automotive servicing industry.

History & Interesting Facts
Wheel weights were introduced in the early automobile era as engineers discovered that even small imbalances in rotating wheels and tyres cause vibration, tyre wear, and steering problems at speed. The first clip-on wheel weights appeared in the 1930s, using lead alloy for its high density (enabling a small, unobtrusive weight to provide significant balancing mass), easy casting, and ability to be crimped onto wheel rims without damage. Lead-antimony alloy (typically 96–97% lead, 3–4% antimony for hardness) became the standard specification for clip-on wheel weights. For decades, lead wheel weights were the universal standard across the global automotive servicing industry. However, from the 1990s onward, environmental concerns about lead, particularly the dispersal of clip-on weights lost on roads into the environment, drove regulatory action. The EU Restriction of Hazardous Substances (RoHS) Directive led to restrictions on lead wheel weights in new vehicles from 2005, with progressively tighter regulations since.
Historical Uses
Lead wheel weights have been used in tyre fitting operations globally since the 1930s. Every tyre change generates the removal of old wheel weights and application of new ones, a single tyre fitting generates several old weights as the previous balance is disturbed. The high turnover of vehicle tyres (typically every 30,000–50,000 miles) generates enormous volumes of old wheel weights at tyre and exhaust fitting centres. Lead wheel weights are crimped onto the rim of steel or alloy wheels and are easily removed with a tyre iron during wheel changes. The scrap trade has dealt in wheel weights for as long as they have existed, tyre fitting centres accumulate buckets of old lead weights and sell them to scrap yards by weight. The lead-antimony alloy used is valuable and recycled efficiently into secondary lead for battery manufacture.
Current Uses
Wheel weight scrap arrives at scrap yards predominantly from tyre fitting centres, fast-fit exhaust and tyre operations, vehicle servicing garages, and MOT testing stations. The material is a mix of old lead weights (grey, dull, dense) and modern zinc or steel alternative weights (lighter, different appearance). It is important to sort the material: lead wheel weights pay significantly more than zinc weights, which pay more than steel weights. Mixed wheel weights pay a blended price below the lead-only rate. Modern tyre fitting equipment increasingly uses adhesive wheel weights (stuck to the inside of the wheel rim) made from zinc or steel alloy, these will progressively replace clip-on lead weights in the scrap stream as the vehicle fleet ages into modern specifications.
Future Possible Uses
Lead wheel weights are in long-term decline as the vehicle fleet transitions to modern specifications using zinc or steel alternatives. EU and UK regulations restrict lead wheel weights on new vehicles, and as the pre-2005 vehicle fleet ages out, the proportion of lead weights in wheel weight scrap will decline. However, the transition is gradual, the UK vehicle fleet includes millions of older vehicles still using lead weights, and these will continue to generate lead wheel weight scrap for at least a decade. The ultimate processing of wheel weight lead into secondary lead for battery manufacture completes a circular economy loop within the automotive sector. Zinc wheel weights will become the dominant type in the wheel weight scrap stream through the late 2020s and 2030s, requiring the scrap industry to adjust its processing and pricing accordingly.
Where Does This Scrap Come From?
Wheel weight scrap comes almost exclusively from the automotive servicing industry. Tyre and exhaust fitting centres, both franchised national chains and independent operators, accumulate wheel weights continuously. Vehicle fleet operators with in-house tyre maintenance generate significant volumes. Rapid-fit centres such as Kwik Fit, Halfords, and ATS Euromaster generate large volumes across their UK-wide networks. Mobile tyre fitting companies contribute wheel weights from their fitting operations. The material should be sorted, or declared as mixed, before sale. Sellers processing large volumes can use a magnet to separate steel weights and visual inspection to distinguish lead (dark grey, very dense, soft) from zinc (lighter grey, harder, slightly lighter for its size). Maximum value is achieved by presenting clean sorted lead weights separately from zinc.
How Is It Remanufactured?
Lead wheel weights are processed by secondary lead smelters, typically through a reverberatory or rotary furnace. The antimony content (3–4%) is managed, some lead smelters retain the antimony, producing lead-antimony alloy suitable for battery grid production (where some antimony is beneficial for hardness). Others refine out the antimony and produce soft lead. Zinc wheel weights are processed at zinc smelters through a different route entirely, they must not be co-processed with lead. Mixed loads require pre-sorting or result in a lower-value blended product. The recovered lead or zinc is cast into ingots and sold into the battery or general non-ferrous markets. The processing economics are straightforward, wheel weights are a consistent, well-understood scrap grade with an established processing route.
5-Year Price Trend & Forecast
Lead wheel weight scrap prices track the LME lead price closely, typically paying slightly below clean lead sheet and pipe because of the mixed nature of the material (some non-lead weights are invariably included) and the processing cost. UK scrap yard prices for lead wheel weights have ranged from approximately £850 to £1,350/tonne over 2021–2026, tracking LME lead movements at a 10–15% discount to clean lead. Zinc wheel weights pay approximately the LME zinc price equivalent, which has ranged from £1,200 to £2,500/tonne over this period, zinc weights are sometimes more valuable per tonne than lead weights when the zinc price is high. Always sort and declare separately for maximum value.
