Shame the i8 specific compound isn't available in larger S001 sizes! I want larger tyres as a little extra rim protection from the kerbs - the grip levels are fine for a road car.
Incorrect the S001 is avaliable on a 275 35 20 with the same compound as the stock sizes 280 A A
This is not advertised as an i8 compound. How can you be sure it is the same?

The fuel efficiency and wet grip ratings differ between the 275 and 245 i8 tyre. This means they are not the same compound.
I listed the compound for you on my prior post : but if you want re-assurance here it's

Rear:
245/40R20 99W Load Range: XL UTQG: 280 A A Sidewall Style:
Blackwall Star BMW (original BMW equipment)

How you can see the compound is the same 280 A A
