Nigel, I posted earlier because, having been a member of the DSR, I well remember that
a lot of Sprint owners encountered rubbing in the inside of the back wheel arches from 185/60 tyres on Sprint alloys.
(It didn't occur on every Sprint though.)
My concern is that an ET31 wheel may have the same problem:

If you read my post on Monday, 10th December 2018 as follows, it might give you some insight into why some Dolomite Sprint owners experienced the rubbing problem with 185/60 R13 tyres on Dolomite Sprint alloy wheels, whilst others did not:
