Hilux tyre size choices

[Norfolk Horn]

I have the opposite problem my older hilux has 255/70/r15 and I carnt find a decent set of mud terrain tyres anywhere

I think that's what I had on my truck, I fitted coppers sst in imperial size but they rub a bit my trucks on a 54 plate alloy wheels.
If you want to know more I will have to check the size for you
