Sweet Melodi Screw in Tire Stud for Car/ATV/SUV/Track/Motorbike,Anti-Slip Screw for Bike/Boot/Motorcycle and Racing Car,Anti-ice Snow Tire with Professional Insertion Tool (L=12mm,200 PCS)

Challenging to install if tires are mounted on vehicle, but once that's done, I must say I was a believer. We have unrelenting ice and packed snow, and I haven't slid since I put these on my all-seasons.

Put these in my snowblower and all feel out of the tires first pass in the snow. They do not grip into the tire well at all. Money wasted.

I stuck these on a spare set of tires and have absolute security against threat of ice and hard pack snow.
