EV System Service Required

Hi. Now, I know there are a number of posts regarding this message and what causes it but I wondered if anyone else has come across the reason that I was given:
I recently replaced the rear tyres at 65000 miles after the fronts were changed at 55000. I came across correct spec Michelin’s with a double A rating for noise and fuel economy so thought I would pay a little extra to see if they helped. Very soon after I got the warning message and took it straight to the garage. Here I was told that, despite the specs being correct, the tyres have different diameters and therefore upset the EV system! Do you think I am being lied to or is this true?
Thanks

I've been holding back to see if anyone had input to your post. This is not something i've come across but it might be worth emailing Mitsubishi to ask the question. ( cs@mitsubishi-cars.co.uk )

I've come across this in the past - around 20 years ago on a vauxhall calibra 4x4 - admittedly not a warning message, but a diff failure. Down to (believe it or not) different sized tyres front and rear. NOT THE Width, but the rolling diameter of the tyres. The new tyres were on the front and measured (i think) 7mm in depth, the rears were down to about 4mm, so not worth (or so i thought) changing. what happens is, as the car is a 4 wheel drive, the front tyres are turning less than the rear tyres to cover the same distance, this over time put the central diff under pressure, and eventually caused a failure.
