Yes, I’m well aware of that

What I was saying is that you’d be doing well to get that information from them (online supplier 3rd party company) as they seem to operate on skeleton staffing and probably wouldn’t have the details at their disposal from some office location, they usually supply tyres from warehouses all over Europe.
I can’t see them emailing a warehouse in another country and waiting for a guy to go and check this information before purchase (whilst presumably holding the tyres to one side for you?) then awaiting your approval before ordering?
If you’ve been successful though, well done!
