A Wheely interesting dilemma

Some time ago I bought Katy some new tyres which were a little wider than the ones she came with

Since then to be honest is is possible to get the tyres rubbing when applying full lock and i believe that this is an MOT failure so I've been looking into the options to resolve it

I considered just adjusting the stops, but to be hones she probably needs every little bit of turning circle she can get

I considered wheel spacers, but the advice from all the people on-line at LRO and LRS on this topic really seems to have come down on the this isn't a good idea. Steve Walford my master mechanic friend agrees with this stance

So it's either back to plan A or have a closer look at the wheels. I've known for a long time they were different. On the front (shown below) the space from the wheel rim top the bolted centre is 6cm

On the back (shown below) it's a little over 8cm.

This makes me think about swapping them around or getting 2 more wheels like the rear wheels to put on the front.

I think I need more advice before I decide so I'm going to call on all those on-line friends yet again (and a few more!)
