I went for Continental Sport tyres Jim and had them delivered to the Wheel Specialist ready to fit after the refurb. £880 delivered.What tyres did you go for in the end Steve, can't remember?
The existing ones don't look terrible, still noticeable decent tread pattern at the edges, probably no advisories there yet I'd imagine.
You'll have them on, just in nice time to get them bedded in and at optimal grip levels for Stelvio likely
Edit : the old tyres are minimum tread depth.
