quick easy question re tyre size

[Adamantium]

Looked in search but I find it clunky, and it tends to only use one of the words as a search parameter.

So, can anyone tell me what the correct tyre size should be for an 18" wheel on an A3 8P.

The wheel is an OEM RS4 split 7 spoke, so not overly wide, 8J I think.

Thanks in advance.
