So I have two Schwalbe studded tires, they're both 700x40, but one is a "winter" and the other is a "marathon winter".

The only noticeable difference is the lack of studs on the outer spots on the "winter".

My question is: which would you mount on the front, and which on the rear?

My tendency was to mount the one with shoulder studs on the front because I could see those mattering in turns. But I could also see the rear sliding out due to the lack of shoulder studs.

Thoughts?

Thank you,

I'd put it on the front since loss of traction in the front much more dangerous than in the rear. In practice both tires probably perform very similarly. Even with studs I try not to lean much when riding on slippery surfaces.

As with any other pair of tires, I would put the better tire on the front -- which in this case, is clearly the new one on the left. Many riders can manage a rear-wheel slide, but few can handle losing the front.

For a couple winters now I've run a Marathon Winter on the front of my ebike. The back runs an old MTB tire that I've threaded full of sheet metal screws. As you might expect, the soft screws quickly wore down while the carbide studs have no visible wear (yet). So I have a great tire in front and a decent tire in back. The front won't slip unless I'm being stupid. When I do slip the back, I can effectively correct for that by steering the front wheel. I don't have a good way to correct a front slide. So this combination is much better than if I switched the tires around.

For your situation, both your tires are good, and I wouldn't expect a huge difference between them. How hard do you lean into turns? I'm commuting on a class 3 (28MPH) ebike, and I'm cornering faster than most cyclists. But I don't think I'm engaging the side studs much. They are more of an insurance policy for if the bike starts to slide out from under me.

Google Schwalbe Marathon replacement studs and get the set that comes with an insertion tool. As others said, the tire in the better shape should go to the front.

I think the main advantage of the outer row of studs is for icy rut conditions and "climbing out," more so than for cornering. That's far more critical on the front. The rear will follow the front for the most part.

It's better to have your rear tire lose traction before your front tire does.

yup, just add them to the tire that needs them

So™, riding with the higher stud count in the front is the way to go. BTW, keep an eye on those particular Schwalbe Winter tires mounted for the rear. They can cause you flats.

FWIW, I know several veteran winter riders who ride studs only in the front. As others here have noted, if the front wheel slides out on ice, you are going down, fast. If the rear wheel slides, you have a fair chance of recovering.

Sorry but I disagree...I've been winter riding and commuting for a long time and I always used both front and rear studded tires if there is any ice along my routes. Loosing control is unacceptable to me, especially if I am riding in traffic....Have you ever had the rear of the bike spin out of control on ice ???. I have and it's not as easy to recover as you think and this happened with a worn out studded tire in the rear. Never again, I refuse to take those type of chances. Another problem with running studded tire on the front is you won't be able to climb hills because the rear tire will spin out and slide, also riding down an ice covered hills with only one studded tire on the front and the rear of the bike will slide out and loose control. Riding through icy ruts will also be an issue with only one studded tire... Sorry I don't like half-assing and I don't like minimum standards. I like to be prepared.

This is @wolfchild's usual stridency, assuming that his experience applies to all and that others don't know a thing.

I've been riding on snow and ice for years. I've ridden with studded tires. Also without, using wider tires at low pressure. I've had skids of all kinds on ice, snow and ice, puddles and ice, you name it. I've gone down at times, stayed up far more times.

So when Mr. Know-It-All says "it's not as easy as you think", he's assuming that he's talking from experience and I'm not.

wolfchild - ride with the setup you want. I don't care. But one day maybe you will learn that your experience and others' are both valid.
