Is this size tyre okay as a spare for my Hilux 4x4?

Howdy all,
I recently got 4 new Yokohamas for my Hilux 4x4. The tyres, as per manufacturer's specs, are: 255/70 R15.
However, my spare tyre is currently an old Coopers tyre I previously had on the car, but since this uses the older imperial measurements, the size is 31x10.5 R15.
Now, when I had all Coopers tyres on my car that was fine, but now that I have 4 Yokohamas with the metric 255/70 R15 measurement on the car, I am wondering whether the Coopers imperial 31x10.5 R15 is going to cause a problem as a spare tyre, because the rolling radius, diameter and circumference will be different?
Also just curious as to whether it would only be a problem on-road as to off-road. In other words, what I'm asking is whether this tyre is safe to use as a spare at all times and, if not, whether it's safe to use as a spare when off-road only?
Hope this makes sense!
:)
