Time for an update.
I tried the Alloygator rim protectors but found them very ugly on this wheel/tyre combination.
I wanted 15 spoke wheels as I hate the look of those split 5 spoke cloverleaf wheels.
I also wanted a car that wouldn't tramline all over the place.
Best solution for me was to ditch everything and buy new 17 inch wheels and fit the new Goodyear tyre:
Eagle Asymmetric F1 mark 2. in size 225x45x17 I have always liked Goodyear as they do represent good value for money.
Eventually decided on Fondmetal 7800 in shiny silver, size 7x17 et35 pcd 5x98mm, as these are a direct fit.
Ordered these from AutoAlloys who had them shipped directly from Italy to me.
This has worked out very well, the car looks better, rides better, has wheels that are now protected by the tyre , no more tramline, and a lot less tyre noise. Handling has not suffered either.
I'm happy happy happy but poorer now!
