ROAR DEAL WITH TYRES
Re the road noise of the tyres on a Mazda CX-5. I am experiencing a similar problem in my 2015 Mitsubishi ASX diesel fitted with Dunlop SP Sport 270s. The car is a pleasure to drive in so many ways yet, on certain coarse-chip surfaces, the noise becomes unacceptable and the radio becomes one’s best friend. You indicate that tyre specialists can probably advise on rubber that will reduce road noise but why is this permitted by manufacturers in the first place? Surely in their testing this problem should immediately become apparent?
Merv Finger-Inverloch, email Few companies do on-road testing in Australia, apart from the three local makers and Kia and Hyundai, which means the others have no idea about the problem. We write about it all the time but the message is still not getting through.
