Right now, my 8N has old 16" truck tires on it. They are REAL old, and dryrotted, and will be needing replacement soon. How much better are the normal 3 rib front tires? I will use this mostly in the woods, and the garden, so I am not concerned about the lawn. Also I have a plow blade on the front of this. Will the 3rib make the steering any easyer? Thanks for any help!
