These are the studs buy.

They grip like crazy. A must here in Alaska with our variable winters and long shoulder seasons.

I use them to make custom stud patterns on my 2.6 wrathchilds (full suspension trail) and my fat bike Dillinger 4 and 5.

Follow the companies instruction for install with isopropyl alcohol and they will not get pulled out.

I rarely have stud shed, and if i do loose a few in a season, it is better than a broken arm. Worth the money.

I bought these to do some winter riding through the city on my Specialized Turbo Vado. Unfortunately, or fortunately depending on how you look at it, we didn't get the normal amount of expected snow so I wasn't able to give these tires a real good test on snowy and icy roads. I did catch a few spots on paved city trails with snow and they seem to do OK. Having never ridden on studded knobby tires on paved surfaces I didn't know what to expect but they do not inspire confidence through corners at speed but that's prob not any fault of this particular tire but just what you can expect of this style of tire on pavement. Still, I think they were a good value and am looking forward to give them more of a test in the future.

Echoing other posters: the greatest advantage of these tires is their versatility. Run at full pressure, they feel like a standard commute or cyclocross tire, with the studs barely making contact with the ground. Run at low pressure (I've gone as low as 28 psi), you can feel them gripping the road and digging into icy patches. This has been great in the past two winters in the Northeast, where we've had only occasional snow and lots of wild temperature swings. I get to choose which kind of tire I need for the conditions on any given day.

My commute is mostly up a steep hill, and these tires are extraordinarily grippy in up to two inches of snow. I've only slipped on large patches of sheet ice on steep slopes. Like others have said, they are narrow and will fall into frozen ruts. Cornering on these is a little disconcerting at first. When cornering at speed, in order to transition from the rubber onto the studs., I have to lean too far. It sort of feels like the tire gets stuck to the road at a certain point and I have to over-correct. Hard to describe, but I've gotten used to it with time.

My only complaint is that I lost about 10 studs on the rear tire after the first season, putting about 25 miles a week on them.

These studs are pretty much impossible to beat for their grip over others studs on the market and they make a huge difference over standard, non-concave studs, especially in fat bike tires that don't have studs on the outer edge of tires. I've had these grip well on dense hardpack ice where other studs just skidded around like they were an ice skate. Very well suited for the Wrathchild 27.5 tires. While a tad expensive for 300pk, at least I don't have to worry about buying any for awhile as my tires shed studs.
