50 Pieces Tire Spikes Tire Studs Carbide Spikes for Truck Tires Snow Studs for Tires Snowmobile Stud with Installation Tool for Racing Car Bicycle Bike Scooters Shoes Boots 7 x 9.9 mm

I used these to stud a pair of Danner boots that double wading boots for fly fishing. I used a cordless drill, taking only a few seconds per stud. I would only recommend using them for super hard rubber-like in tires or heavy-duty boots since the stud thread is very aggressive and might tear up weaker materials.

These studs are exactly what I needed, they were so easy to screw in, and yet they stay in well, and have lasted well also.

It should have been about $20 for this, I should have paid more attention. Beware , you get a small handful of studs for over $60. I bought from 4 different sellers at the same time. To compare...

A full 3mm of of stud left after hard driving! Great studs!

Looks like a really decent product but they don't know how to count.

Easy to install

I bought these because I couldn't find smaller/shallower tire studs, and while they do work... at least 10 of the 50 were poor casts, and didn't work with the tool provided. That is a failure rate of 20%? At 85 cents a stud? I think with shipping cost - they are over a dollar a stud?!?As far as markup per item? This is an astonishing poor price - especially with the high rate of flawed units. But they do work, hence the 2 stars.

Labor intensive
