Are UK and American Tyres Different?

[scottish grinnal]

Just had a letter from my Insurance company about the
repairs that have been done to my TR, It had the same tyres allround
before the accident and when it came back they said they couldn't get
the same for the front. I found the tyres but they were in America, the
engineers who past the repairs said thatthe Tyres would be of a different
specification from UK tyres.
The pictures of the tyres in America looked the exact same and had the
same writing as the rears, is the engineer talking B*LLSH**E or is there a
differance?

Tyres in question are below
