Thanks man - could I ask for an example from above?
Your list says: for 19" rim: 7,5JX19 ET32 (245/50R19)
However this URL states a compatible rim but is 8.5Jx19, with tyre sizes 245/45R19
https://www.wolfrace.co.uk/8.5x19-wo...k-alloy-wheels
Based on the fact that the 19" rims on my current M-sport 245/45R19, does this not lead one to presume the 8.5x19 is correct?
I apologies again for my ignorance in this matter :-)
