Unless you’re not already running on 20” wheels, I’d say that’s all. What do I put here then?

They have the same rolling radius so nothing to do unless you up to the 255/ 55 r20 tyre. Standard being 255/ 50r20. The speedo will read correctly in that case instead of overeading as standard. ( Its so you dont speed as you think your going faster than you are ) 7% overread is normal.
The new wheels have different offset so will give more inner arch clearance and "fill" the arch for a better look.
You can let the car know its now on 20" rims via a diagnotic tool but I didnt bother. You will have no issues and can do it later if you wish. 2007 Vogue TDV8 in Zermatt Silver with Charcoal

Fitters should sort that

Think they put mine into access mode to do it. What do I put here then?

Unnecessary quote removed

The new tyres are 255 55r20. I assume therefore that my overall wheel diameter is larger and Speedo will be slightly wrong 2007 Vogue TDV8 in Stornoway Grey with Jet interior NOW SOLD

The speedo will be correct on the new tyres.
They are designed to overread from the factory.
So on the original tyres, the speedo would be showing 60mph, actual speed would be 57mph.
On the larger tyre it takes that error out so it is accurate. 2007 Vogue TDV8 in Zermatt Silver with Charcoal
