Find one that can/will. I took my salt tires/wheels to have them balanced, they said they couldn't be balanced. Took them to a different shop, he said you spin them and ad weight where told, spin them again and ad weight where the machine says to, spin them again and ad weight. Every time the machine said less weight and a different place than the time before. They balanced. Other than that add balancing powder that they use in semi truck tires, constantly balancing.
