hi all
is it ok to use 3 old style and 1 new km2 mud terrain tyres?
cannot find any info on that, looking at the threads, they are slightly different

If I had to, I'd use two of the same type on the front, different tread patterns on the rear.

Normally not recommended, and I always buy 4 at a time, but the spare is a Michelin so occasionally I'd have a mismatch with the nexens that are fitted on the road wheels..
