Spotted one odd size tyre on car! Been on it for 2+ years Change it ?

[Pras]

As per title, had the car for 2+ years now and never spotted it.
It has been for a service and 2 MOTs in my ownership and they never noticed it either.

SO I have 3 tyres 205/40/R17 and 1 215/40/R17

Still has 5mm thread left.


What shall I do change it for the sake of it ?

I know its been on for over two years but I would change it in the interests of your safety. Its not good really to have different sized tyres on the same axle but it is entirely up to you.

Cheers
