For on-road TOD use you need to have the tires within 1/4" Circumference. This means that even 2 tires of very similar wear and brand and model etc can be off (I had this problem when I first got my trooper) so be careful of that for onroad situations.

For offroad low traction it probably won't be a problem since slippage can occur but I wouldn't recommend it either way.
