Quick questions on tyre size options!

[Griff Boy]

Hi,

I run a BMW X3 3.0i sport on 255/45/18 rears and 235/50/18 fronts and Im trying to get a set of winter tyres.

My question is what widths can I run on my standard rims? ie can I run 235/50/18s all round on the same wheels? I understand that their is a BMW guide to reccomended tyre size options in the manual, but I cant see it!

Basically what are the size options for me?

Thanks in advance for the help!

Not really, I just tried this calc myself, more to do with the circumference of the wheel not the width etc.

But thanks very much for the quick response!

What width are the wheels? There are guides on some of the manufacturers sites (Continental definitely). Sticking my neck out I'd say you should be fine...

Yes, you will be fine with the same sizes all round and the size you indicate would be perfect.
