Review on Marrkey 12mm Carbide Screw Tire Studs for Enhanced Traction on Snow/Ice - Anti-Slip Spikes for Car/Snowmobile/Tractor/ATV/UTV/Motorcycle/Short Lug/Bicycles/Shoes with Easy Installation Tool - Pack of 100 by Jeremy Yuusuf

My old lawn mower tires are badly worn, the mower has seen better days and I couldn't justify buying new and expensive tires for my old mower. I just put little lugs in my old all plastic tires and now it's like 4WD and no it doesn't tear up the turf, the little lugs actually act like aerators. I used a 1/4" impact wrench and the included driver and installation was a breeze.
