Just had some new tyres fitted recently, Kumho PowerMax 769 215/65 R14. They were fitted and balanced (on-car) by the same crew who have always done my tyres, never had a problem before. Anyway, I've noticed that I'm getting this vibration now, particularly over 90km/h, that is really irritating. It's not a physically big vibration, but the frequency of it buzzing up my arm makes it quite noticeable. Took it back and they rebalanced the tyres, but it's still there... It must be something to do with the tyres, would be too coincidental if something else started causing it just as the new tyres went on...
