I read in a previous thread about adding 3 lug nuts, opposite the CTIS valve, to balance a tire. I tried this on the front left and it made a noticeable difference. The 3 nuts weigh 1lbs 2 oz. I removed the cast wheel weight and traced it's outline on some sheet lead. Took 5 ply of lead to equal the 1lb 2 oz. Put the lead on and then the wheel weight over it and tightened it all down. The lead doesn't show and the wheel is "balanced". I'll give it a test tomorrow and report in.
