haven't scrounged for wheel weights for about 5 years, but it pays to visit the various tire shops. Some are more than happy to give them to you for free, one shop in RTP charged me$5 for 20 lbs or so, i bought some cause I was low on lead at the time. Another thing to do is when you take your car in for new tires or service, ask them if they have any wheel weights they want to dispose of. i've found, again based on 5 years ago, you can get as much as you want for nuthin'
