Hi all,

New owner X5 Xdrive 40D M sport 2013.

Currently has worn out Bridgestone run flats 275 / 40 / 20's on the front which need replacing.

Done a search as tyre discussions can be a pain on forums and didn't find anything useful tbh.

It will only be used on road so what experience do you guys have? run flats or change to normal tyres?
which tyres are getting life v cost benefits?

Thanks,
John.

Hi I just picked my X5 up last Saturday.
It has bridgestone runflats on good tread on,but when it comes to change them I will stick with the same.
And I will change all 4

Stick with '*' marked tyres and change as a set.  Changing a pair only, or not using '*' marked tyres brings a risk of differential/transfer box failure.  These X cars are very fussy about tyres, especially where you have a staggered set up - which the 20" wheel set is (different sizes front/rear).

You don't have to stick with RFT.

From what I have read and gleaned here I would agree with Glen and X5Sport as there are lot of posts about probs and an easy route out for company if under warranty if you don't have correct tyres or set of etc.

4wd for BMW have a small tolerance but it's not worth saving a few hundred quid when the risk of replacing a diff goes into thousands esp BMW prices.

There was a recent post on a and although on an X3 same applied and the person found that their old tyres difference between front and rear in height and therefore circumference and was causing probs some skipping with transfer box. He had a complete new set of tyres and Since reported the problem is no longer there.

I did some research about 3 years ago and at the time people were having issues with X3's and non star rated tyres but didn't find much on the X5's.
I fitted a set of Michelin Latitude sport 3's non run flat tyres and have done about 20-25k on them with no issues.

The key for you probably is that is was a set.  The E53 seems to be more tolerant than the E83, and by the sound of things the E70 family too.
