I purchased the Grip Studs to install on the front tires of my tractor to get better traction while plowing snow. I had tried chains on the front tires but they were risky because if they loosened up they would bur against and bind on the axle. The Grip Studs were easy to install and have performed very well, a great improvement in steering traction while plowing snow. I chose the Grip Studs because the auger style made more sense to me than the screw style of competitors. I plan to leave them installed on the front tires year around since the tractor only sees dirt and gravel. Based on my minimal experience so far, I think they will work out just fine long term. I contacted Grip Studs to verify the size / model to use for my tractor. I received a quick response. I made a second purchase to install more studs on the tires since I initially miscalculated how many I would need. My neighbor also purchased some Grip Studs after he saw them on my tractor.
