bmw z3 2.8 18 inch rear tire size 255 vs 245?

Ouch, did a quick check and I'm seeing £600 and upwards. Maybe not then.

Oh yes!
Covid killed the company I used to hire from, Shiply quote was nearly £400, puts it well out of the budget.

Just a thought - has anyone ever asked for approval of oversized tyres from their insurer? Tyres may now be regarded as cosmetic items, but insurers would view such things as a good get-out clause. Here in France - and Germany - non standard tyre sizes could result in an MoT failure.

Yes it was something I've always done with insurance companies I've used since I did the "mod" back in 2013 along with fitment of front strut brace and non OEM Alpine DAB radio (professionally fitted).

Exactly, box for that too
‘Manufacturers alternative fitment’ I think it is, had to tick that last week for mine.

Would retrofitting cruise control fall under this? I’m guessing, yes
