Anyone running tire balancing beads? Had a second set of Cooper Discovery STT tires in stalled and the where having problems getting the tires balanced. They suggest using the tire beads. Didnt have problems getting the first set of coopers to balance. Heard the beads can mess with the TPM's. The tires are the same 315x75x16 as before. Does this sound right or should i seak another shop to see if they can balance. Thanks in advance for any feedback!
