well there is alot to this subject.. now on my HDs I got after market wheels & tires,,(proformance machine on the softail...& colorado customs on the street glide) neather of them required any weights.... on my big dog I didnt have any on the frt but it did have them on the rear. I removed the rear weights & installed the dyna beads in both frt & rear tires.. I dont notice any difference.. so with no weights.. I'm happy.. thay all ride smooth & no weights.. do a search on dyna beads... jake can hook you up...
