These tires have been great! I commute to work everyday in northern Vermont, where weather can vary from day to day. These tire have served me well during snowy rides and the nutty thaw freeze cycles of VT.
Doing 7 miles/day commute in Boston year round, on a Raleigh Misceo 2.0 hybrid. These studded tires allow you to ride safely on smooth ice. Previously, on plain rubber tires, any small patch of ice could cause a skid and loss of balance, with these studs it's no problem. They don't solve the problem of thick rutted ice or deep snow, but that occurs less frequently.
The reflective sidewall is a bonus, giving excellent side visibility on dark winter evenings.
There's a little extra noise, and noticeably more rolling resistance, but it's well worth it to feel safe in winter conditions.
I planned on leaving these tires on until spring, rolling through the snowy, icy days and the drier days in between.
I took them off after one day.
I expected them to be kinda sluggish, being studded snow tires, but wow. They are heavy, stiff, noisy, and slipperyyes, slipperyon anything short of blade ice. I didn't think a tire could be so harsh, even at low pressures. I didn't think a tire could be so skittery on asphalt. I didn't think studs could be so ineffective in snow.
My knobbly CX tires (also Schwalbes) outperform these on every surface but blade ice, even crispy iced snowpack.
Save these tires for your zamboni.
Used it in Washington DC for few weeks. Tried on fresh snow and it works perfectly. When no snow, it's an extra work (and sound) to ride with, but it's usable (I have only one commuter bike so I let my studded tires on it for weeks). I haven't tried on black iced but friends told me it doesn't work.
I haven't lost any stud during that period, and I had no flat.
Bought these many years ago at LBS. I put approx 25 miles per week on them Dec-Mar. Treads and studs are still good after at least 5 Northeast winters. No punctures yet for me or my wife. They've saved my butt when I hit an unexpected black ice puddle in the dark. I'd buy another set, but I might not need them for another 5 years.
The tread is pretty mild, so they're not great when the snow gets deep. Not so many studs either, so don't lean too far over. They are slower than what you ride in the summer, but if you want just enough winter traction, these are good compromise. If you want more traction and more studs, get something knobbier, and be prepared to go even slower. These are around the same level as the Nokian A10, which is skinnier with a more square profile.
Put these on a Specialized Diverge and did some riding on a path that had stretches of packed thin snow and ice, but quite a bit of pavement showing through too. They did ok on all surfaces, which is what you want in a winter commuter tire.
I even got them out on a frozen lake. Probably not the best application for these lightly studded, commuter oriented tires, but they did work ok at slow speeds.
Great tires, Just like a marathon but with studs and some extra knobs, there are empty holes that you could put in another row of studs if you wanted, but it works well enough on ice without.
Put the studded tires on my commuter bike. I try to ride a few times a week. I took a spill in December so bought these, they really give me confidence on the icy spots of the road.
I've been using these tires for winter commuting in Montana for a couple months. They have generally done a very good job at keeping me upright through snow, ice and slush. The only complaint would be that if the snow has really been packed down and turned to ice chunks and you end up in a tire rut (e.g. on a non-plowed side street or something), and there is built up ice on both sides of the rut, the lack of studs or knobs on the edge of the tire make getting out of the rut a little dicey. But I'm not sure there is much that could be done to really solve that problem anyway. I would definitely buy these again.
I'm a Michigan transplant so frigid winters are relatively new to me. Last winter I was taking my chances with rubber on ice, everything is fine but suddenly I'm on my back, still clipped in, headlight and water bottle skipping off the trail in opposite directions. Time for studded tires!
With these tires I'm confident on solid ice, like frozen lakes or just thin cracking patches of ice. You are only as secure as the ice you are riding on, so I have been on a sheet of ice that slides a bit, even though the tire maintains traction it is possible to slip out a few inches. Frozen earth and gravel are no problem. This is my cross bike, so I've been over every type of terrain with no issues except deep show where only maybe a fat bike can go. Even dry pavement is ok, the zing of the spikes is actually less than I had expected. I'll keep these tires on through winter, ice or not. Co-workers think I'm crazy to commute in conditions they can't even walk in!
I didn't know what to expect but I like them. Good grip on icy pavement. Too thin to provide a lot of benefit in measurable snow. The studs make. Nice humming noise which shouldn't have surprised me but did. I recommend the tires.
We had a pretty gruesome winter last year in Boston, and these saved my ass on a number of occasions. Important to note that if you corner too hard, the spikes can't save you. Rode about 2000km without a puncture, and lost only 4 spikes, so I guess these will survive a few more winters.
I put this on touring bike rims (Cannondale T2000), and headed out along my usual trail. There was glare ice, rough ice patches, and some crunchy snow along the way. The tire performed perfectly in all cases. Smooth, no slip on the rear while accelerating a bit on the glare ice, stable tracking through the rough patches, and like the snow wasn't there for the crunchy stuff.
It did take more effort to pedal at my usual pace, but not overly so. The rubber part of the tread is fairly aggressive, so I would suspect it to be decent in dirt, but not mud. The noise of the studs was noticeable, but not overly so. I was careful turning sharply, as the studs do make the front wheel a bit more skittish. I wouldn't take these tires down my CO mountain road at 35 MPH, but I would at 20 MPH, and slowing on the icy turns, just like one does in the car with studded tires.
I've run studded tire on my cars for 30 years, and these tires are as well built as I've seen. At almost 200 lbs, I put a lot of stress on these tires with no missing studs and no noticeable wear. If I were commuting, I would suspect I could easily get 1000-1500 miles of use riding bike trails.
I live in Ontario, Canada and ordered these for my winter riding needs which includes mostly gravel or chip-seal country roads that are snowice packed from Dec through March. In addition to traction issues we have quite a few steep hills here, putting a premium on traction for ascents and descents. I ride throughout the year and average about 100kmweek in winter. Before trying these tires I had successfully used Trigger Pro and Sammy Slick in winter. Both are file tread tires with side knobs. The file tread allows them to clear quickly while the side knobs, when they kick in, provide a chance at staying upright. Suffice it to say that it's a white knuckle ride! FYI, I have never flatted in winter (I use Conti butyl tubes with Stans's compound inside them).
Having read various reviews of spiked tires I thought I would trade up in traction and safety.
For my first ride with these tires I chose a 35km route that included pack snowice and some clear asphalt, basically anything I would encounter in a typical winter ride.
Given the weight of these tires compared with 300-325g for the aforementioned semi-slicks, I was expecting a slower ride. Even so I was surprised by the increase in rolling resistance. At 50psi, these tires were hard to keep rolling on every surface I encountered. Plus, they hey were noisy to the point of being annoying, and after 35km I felt like I had ridden 75km. But even more surprisingly they offered little, if any, upgrade in traction over my usual rubber.
Perhaps tires these aren't meant to go fast and the resistance curve bends sharply up past a certain speed (likely) or perhaps I could lose several watts of resistance by tweaking tire pressure. And perhaps they get better after a break-in period.
I'm wiling to give them another try, but boy, given how noisy they are, this might not happen for a while!
Conclusion some upgrade on snow and ice, although surprisingly little in my experience, vastly increased resistance and noise.
Affordable winter road tire that takes the scare out of riding in light snow or potentially icy road conditions. Increased rolling resistance as expected. Studs have stayed in place and grip road well. Certainly not a fast road tire but keeps you riding during winter months . Very satisfied with the purchase
