Marrkey 12mm Carbide Screw Tire Studs Snow Spikes Anti-Slip/Anti-ice for Car/Snowmobile/Tractor/ATV/UTV/Motorcycle/Short Lug/Bicycles/Shoes with Installation Tool - Pack of 100

Put these on my rubber tracks , mini bull dozer , worked Great!!! No more sliding sideways backwards or forwards on steep driveways removing snow and ice. These are easy to install with the tool that comes with them, DO NOT pre-drill to install, just use the tool provided. I pre-drilled appx 20-30 studs in my under carriage. Lost every stud that I pre-drilled the under carriage for. Screw them in, set them fairly deep and they will stay put and give excellent traction on ice andsnow.

These are easy to install, and remove at the end of the winter if you choose. I find they add some traction to t driving my Side by side on ice. For the price and the ease of installation, very worthwhile.

I installed in my new winter tires and they seemed to be ok first trip out. As I drove and turned sharply on the road I could hear them flying out of the front tires and when I stopped to look a few had flown out. The back tires seem to still have them. I will be removing them out of the tires. My new tires had big holes for studs so this may have been the problem. They seen to be wearing good and would last one more season if left them in.

Super easy to install and really helps with grip in the winter. Way cheaper than having a shop do it.

I ordered my carbide spikes & got them on time. I like that the bit that came w/ them isn't just a bit for screws but for these specific screws.Wish me luck on the ice 🥶⛸️
