My X5 came with 20 inch M sport rims and Dunlop sport maxx tyres but I've just replaced the fronts with bridestone dueller sport hp tyres. The fronts have 8 mm of tread depth and the rears 3mm at the centre, 4mm at the sides. Is there going to be a problem with transmission wind up given the slightly different rolling diameters? Many thanks in advance for any advice offered.
