Tire performance on a mower is directly dependent on the soil and moisture of the lawn.
Obviously a wide tire is best for going in a straight line, everybody agrees on that. Are narrow tires better for turning? Not necessarily, true they do have a smaller "footprint", but they also have more PSI than a wide tire.
We've evauluated tires in various conditions and have found that wider is better for our application.
I would have to agree, wider is better, more stabel,less pressure on turf, and if you know how to turn your z they don't even make a mark. Mine don't sink as bad as the narrower tires either when its damp.====== Marks Mowing Service
