I got a large load of wheel weights recently and in there were some huge truck weights. I had an automotive shop for many years and never ran into anything like these. When I was driving a truck I saw them on the wheels but they looked normal in size compared to the wheels. Note the medium size 2 1/4 oz. car weight on the clip on truck weights and the strip of car weights on the truck stick on's. The thinner clip on's are 12 and 14 oz.! The bigger ones are not marked. And all of those stick on weights are much harder than soft lead. I am going to check them in a few once I warm up.
