And if you've changed them since, did you stick with the same. If not, why and what difference has it made?

 

My E60 525i has got dunlop run flats on

I have some nasty "handling problems" which were made a lot better when my dealer took off my 7.5 x 17 rims with 225/50/17 Dunlop tyres.

Replaced them with 8"x 17 rims and 245/45/17 dunlop tyres and the car was totally transformed.

It was superb.

Then 3 days later I had to swap back. Issue now in the hands of BMW GB.

See my thread "vague steering"

Are you having problems?

 

I don't get my car until mid April. I posted to see what I could expect when it arrives.
