So I have a set of Kumho Ecsta Supras. I know they suck, but they've performed allright so far and they were free, so I took them. Anyway, I got them balanced a week or so after I got them and on the way home from the shop I think the weights got thrown on both driver side wheels. After that, the car rode really rough from 45 to about 75 mph, and I began to hear a noise that sounds like that noise you get when you were a kid and put baseball cards in your bike spokes. So I just took it in again. Told them about the noise, and had them rebalance and align. Got it back, still have the noise, and it's getting even worse. I'm wondering if anyone has had this before. Are these tires just really noisy or is there something possibly wrong? Thanks for any input. Happy Father's Day to those of us who are
