Fitted on reversed will reduce wear and increase traction. The downside is that they don’t clean themselves as well. If your tractor is used mainly for fieldwork in the summer and loading duties in the winter it probably makes sense to reverse them. If you use it for any amount of cultivating then I wouldn’t. The rear tyres on my combine were fitted reversed from the factory and I haven’t turned the round.Going to replace the front tyres on the loader tractor. Do I fit them as normal or reversed. Seen some with reversed tread , does it make a difference?
