Has anyone ditched the runflats for normal rubber? I am thinking of getting rid of the 17" wheels with run flats for some 18" with normal tyres. Looking at the 328 rims with 245/45/18 Dunlop sport maxx tyres.
Would this setup on an 520d SE sports auto improve the straight line wandering that seems to plague the F10. To be honest my car is pretty good but you still need to make very slight corrections at motorway speed on certain surfaces, which leads me to think it's a run flat tyre issue.
