Studly question

Probably more related to the turns and the likelihood of sliding out. In five winters of riding Schwalbe Marathon Winter Plus studded tires, I have only lost a coupe of the studs. Of course, those are on a 35+ pound old rigid mtb that I can’t get to go very fast in the first place.

Cornering traction is an issue with studs on dry pavement.
Yep, that’s what I meant to say.

Peter White recommends not riding “too aggressively” on studded tires? What does that mean?
You want to avoid excessive lateral stress on the studs, as when braking suddenly. Or, as I discovered, riding along the side of a concrete slope (even just a 6″ curb). Or, I guess, sprinting too fast.
Speed isn’t a problem, it’s acceleration, deceleration, and lateral force.A few times in the 2 winters that I’ve ridden studded tires I’ve noticed studs halfway out after the sorts of maneuvers I described. I carry one of those tiny Swiss Army knives, and the screwdriver blade is perfect for poking the studs back in place. Last weekend I mounted the tires for this winter. I only lost one stud last winter. My first winter was the worst, I think I lost 6 that year. (A few companies sell replacement studs, and the good carbide-tipped ones are apparently all about the same size. I use the inexpensive set from 45Nrth, and use Nokian’s tool for inserting them; I see that Universal has an inexpensive 45Nrth tool now. Here’s the blog post mentioned in the Universal replacement stud comment: http://thegoldenwrench.blogspot.com/2010/11/replacement-studs-for-studded-tires.html) Riding with 6 studs gone was no problem, I just prefer keeping the tire full.
I run these all winter so I can ride every day without worry or the effort of keeping up with the forecast & swapping tires/wheels the night before. I know it’s likely overkill (I used to ride Chicago winter streets on plain 28c touring tires), but running the studded tires is nicely reassuring.

Out-of-focus photo from a couple days ago that illustrates what apparently can happen to the studs (getting pried out). I took this before trying to fix it; I lost the stud when I managed to propel it out of the tire somewhere onto the patio. Oh well.
