here is an article on taping for ya; (

Also, I have badlands on LPR 1/2" offset rims.;
I taped mine because w/o the tape, they were as big as dinner plates over 50MPH.
Now, nothin. They are awesome. Mine are not balanced either. I tried to balance them using some hot glue on the inside of the rim, but that added too much weight and did not help with the wobble.
Now, I only notice an imbalance over 50 mph. But its much better with tape than without.
I used gorilla duct tape. That stuff is awesome. It could practicly stick to water.
