Selected entries from the named UK BMW tyre-label table. Model years and trim assignments are not stated. The body style and standard/run-flat construction shown in each row are part of the reference; front and rear entries must not be interchanged. This is not an approved wheel conversion list.
Check your exact vehicle. These are selected documented combinations, not a registration lookup or a complete fitment list. A tyre with the same size can have a different load index, speed rating, construction or manufacturer approval.
