On a 2WD, with no brakes on the front wheels, there is no utility in the front tires providing forward/reverse traction. The only tractive force they need to provide is horizontal force for steering. That’s the reason for the continuous rib design. In terms of the sideways tractive force required of the front wheels on a 2WD, if you want a truly more aggressive tread, go with a single rib instead of the 3 rib.
All that said, you can put whatever you want on there so long as it fits the rim. If you never need to steer on soft ground it probably doesn’t matter much what you pick. Just know if you go with something like a R1 ag tread designed for forward traction and need to steer in mud or soft dirt you will need to be good supplementing the steering wheel action with brake steering.
