Had a new E3 put on the rear today. Not sure of the exact weight they had to put on to balance, but there are 3 different weights on the rim. I'd like to put in Dyna Beads and get rid of the weights. For those that have installed them, how do you know how much to put in? Do you simply let the air out, remove the valve core and put them in through the valve stem? Any issues with TPMS? TIA.
