Replacement tyre when part worn

What's the general consensus when replacing a rear tyre when they're part worn (c.3.5mm on MPSS)? I picked up a complete side wall tear from the lovely heritage granite kerb stones in the local market town when a pedestrian decided they couldn't hear the V8 and walk into my path.
Would I be better off replacing two and keeping one as a general spare?

That is what I would do.

Turns out that another tyre has a bulge in it as well!
So, I'll get two new tyres across the rear axle and move the one good one at the rear to the front which is the same tyre and similar tread wear.

Sounds like a plan, but I would put your new tyres on the front - most of the braking and all of the steering input is through the front, so that's where you need maximum grip.

The old rules states that you always want the best tyres at the back, for stability and security. Maybe not so noticeable nowadays with ESP etc. but you can't get away from the fact that you want the best mechanical grip on the rear tyres.

I'd rather have the better tyres at the front to make sure I can stop when needed.

If if doubt stick it in the back is the default position to cover all types and specs of car, but not a hard and fast rule - as Continental point out in link above, some car manufacturers say the opposite. In a 4wd car with ESP etc I would say steering / front end stability in the wet more important than risk or understeer so I would prefer best tyres on front. But, as you say, each to their own.

Those seem like guides for people that have no idea how to drive. Their justification for putting on the rear is that oversteer is bad and it is better to understeer. Yeah that's great if you are an idiot and don't drive around corners at a suitable speed for the car and conditions but personally I don't do that, I'll slow down if its wet or icy or if I have worn tyres. However, I can't control someone pulling out in me in the wet and having to make an emergency stop. That's why I prefer to have better front tyres.
