Maaaaaaaaaaate - thanx for good info (you suck LoL) why am I the only one who has a noisy Jk D'oh.... its not my tyres (I don't think) - maybe its my light bar - Have you driven from Sydney to Newcastle @ 110kph - I have made quite a few trips to Melbourne and the noise just gets to me - ergo the Cesna Headset cheers Hunty
