Got a quick question for anyone who used these before. Just got some new cooper stt pro's mounted last night(315/70r/17. The shop used balance beads and I'm getting a shimmy in the frontend from 40-55mph. This is the first time I had these beads installed, so it's all new to me. I'm not sure how much they put in, but the shop does a lot of bigger size tires and never had any problems like this before. My understanding is there's a chart that tells you how much beads to put in on a given tire size. They want me to drop it back off for them to tear them back down and see what the issue is. I'm just looking to see if anyone else knows how much beads were used in mounting your 315's. I'm not 100% but I think I overheard them saying they used 4.5oz in each tire. I'm looking on the Internet and seeing multiple charts saying 8oz for my size.
