No, no; was using that as a previous example of the issue I have. Thanks for the offer!

When the E39 failed, am almost sure it was a 225 tyre that looked quite stretched. Had always had 235s on it previously. Didnt question it at the time as they were needing to be replaced so stuck on new boots.

Now I've a set of 225s winters that I'm putting on a staggered set but the NCT is due next month and dont want the hassle of rotating again if they fail the stretch!! The right tyre obviously being 245. Some say they've passed on stretched and others say they have issues....wondering if they have a set rule.
