Ashton1 Posted March 26, 2011 Report Share Posted March 26, 2011 Hi Tony and all other members, You may recall i used your services a few years back to correct some balancing issues, and your help was greatly appreciated. I have just purchased a new BMW X5 40d M sport. The car is lovely however i am not enjoying the drive at all. It was delivered on 1st March this year and since then i have covered nearly 1200 miles. The issue i am having is that the car feels unsettled at speeds over 40mph. There is no vibration whatsoever and i have tested this on various road surfaces and speeds so i dont think this is a wheel balancing issue. I was just wondering if you guys being the best i have ever come across can find a solution for me. its not that the car is not drivable but it is irritating as i am quite a focused driver. ps. i have tried experimenting with the tyre pressures and found that if i lower the pressure 2psi it improves the car very slightly. I look forward to hearing from you. Quote Link to comment Share on other sites More sharing options...

Ashton1 Posted March 28, 2011 Author Report Share Posted March 28, 2011 Hello.......The X5 has some issues, is it on the runflats? Yes mate it's on run flats bridgestone duellers 275/40/20 on the front and 315/35/20 on the rear Have you had any joy with these? Quote Link to comment Share on other sites More sharing options...
CIH Posted March 28, 2011 Report Share Posted March 28, 2011 Could be a number of things but factory sport geoetry means too much camber for the runflat tyres to accept. They can't deform like a convential tyre would. Quote Link to comment Share on other sites More sharing options...
Ashton1 Posted March 28, 2011 Author Report Share Posted March 28, 2011 Do we have a solution? Quote Link to comment Share on other sites More sharing options...
CIH Posted March 29, 2011 Report Share Posted March 29, 2011 Yes, less camber. They are adjustable from the factory on the rear and the front doesn't tend to suffer so much. Quote Link to comment Share on other sites More sharing options...
