On the one hand it's the only thing left! On the other my V8 started doing that the first time I changed the tyres, and has done it ever since despite further changes and repeated rebalancing. I'd like to do an on-car balancing but no one seems to do it anymore. With mine if I'm on the straight the vibration will fade in and out once every 2 or 3 secs or so. If I'm on a slight curve one way the rate speeds up, if the other then it slows down. I.e. it is definitely wheel wobble, both wheels are doing it, and they are alternately cancelling each other out and adding to each other. Why it should fade in and out on the straight when the wheels, tyres and pressure is the same is another mystery, as that implies they are rotating at different rates.
