There's usually something easily replaceable as a "fuse" - on series Landies, with no centre diff, it's the rear halfshafts. Don't even need to jack the thing up to change 'em - the only fun is getting the inner half of the broken one out.

There is no way that fitting these tyres would have caused the differential to fail.

255 tyres are wider than your standard 225 tyres but wider tyres won't affect the differential.

Having tyres with a taller side wall would damage the differential but this doesn't seem to be the case.

The tyre profile is a %age of the nominal tread width.

Let's assume they were 255/70 instead of 225/70. They would have had a 70% of 30mm taller sidewall - 21mm taller.

To be roughly the same as 225/70, they would have to be 255/60 (4.5mm shorter). Since the OP didn't mention the profile, we can safely assume they're the same.

well the height of the sidewall is a % of the width of the thread. It's pretty hard to match the overall circumference with different width tyres because they only go up in 10%/5% jumps. So they will never 100% match.

In any case you have to assume that if OP had 225/50/r17 on they probably put in 255/50/r17

Since it was presumably a transposition error, we can assume the profile was the same

And the fact that the drivertrain actually blew up. Some people love to be smart alecs and point out irrelivant points.

TBF, many people don't realise the profile is a %age, but think it's an absolute. So all (say) 60 profile tyres are the same sidewall height, regardless of width.

When you look at the tyre size, it's not the most obvious combination of measurements...

Tread width (mm)/Profile (%) x Rim (inch) - Load rating (numerical code) Speed rating (alpha code)

I ordered 42 waist trousers instead of 32 waist.

Whilst walking around, they fell down and everybody saw my bum.

Who do I sue?

I did not know this. Every day is a school day.

If you are going to make a sarky comment at least spell it correctly.

Two words out of four isn't too bad, I s'pose, although 100% of the punctuation was abused.
