Yes, definitely get the spin balance if you like the corrosion created on your aluminum wheels by the steel weights. (No more lead weights allowed-environment). It has been my experience up here where salt is put on winter roads that salt aggravates quick corrosion on aluminum wheels by the use of steel weights. I lost 2 wheels on my Denali to said corrosion. Have used Dyna Beads and I'm a believer. Your tires are rebalanced everytime you start moving.
