Personally I think tyre rotation is a bit out of date these days. Many tyres are directional so can only be swapped front to back anyway and if you do swap them over you end up buying a full set of tyres at once, whereas if you don't you only buy them in pairs. Swapping fronts to the back and backs to the front would be no problem with the MG TPMS, you just have to remember that the pressures you're reading at the front are the back tyres and vice versa.
I swapped the front tyres to the back when I had a 2010 Prius and the road noise became intolerable, it must've been something to do with the wear pattern, so I swapped them back.
This is the very reason that the VAG group recommend a front to back rotation every 5,000 miles.
The tyre wear on a lot of there cars, suffers from the rear trailing wheels / tyres suffering from a condition called “Stepping or Sword Toothing” across the tread pattern of rear both tyres.
It is a common and well known condition.
The OEM suspension set up is the cause.
Rotating them every 5,000 miles prevents this condition and eliminates the problem getting to the stage, when the tyres start to drone when they are switched around to late.
That is why it is every 5,000 miles.
I agree that tyre rotation will mean that you are replacing ALL four tyres at the same time, but you have to remember that by rotating the tyres they are on the car longer in the first place !.
Which then brings me to the next reason why I believe you should rotate your wheels / tyres.
Tyres today suffer more from side wall cracks than they once did because more silicone is used in their manufacture.
UV is the biggest culprit here.
This could result in the rear tyres getting replacing prematurely, with plenty of thread remaining, due to a MOT failure condition due to side wall cracks.
I hated the OEM Bridgestone’s fitted to my previous car with a passion !.
They where hard, lacked traction and had really bad road noise.
I wanted them all off together, so rotating them enabled me to run them down equally, before finally replacing them ALL four tyres with some decent low noise Good Years.
Each to his / her own I guess ?.
