Has anyone successfully made DIY studded tires from Nokian studs? I have a tire with a damaged bead, so there are 240 extra studs in my garage. I don't want to use the standard screw method, as I ride quite a few miles and keep my studded tires on until I think winter is done, or at least taking a couple week hiatus, so there would likely be significant wear issues.

Thanks!

There's no way that this is ever going to work. The studs stay in the tires on account of their wider bases and appropriately shaped rubber cavities. There's no practical way that I can think of to make those holes aftermarket.

Look at it this way: considering the price the replacement studs go for, you got a good deal on your lot of 240 replacement studs for you next Nokian

Get some more Nokians, but you won't need the spare studs as these don't shed their studs and should last the lifetime of the tire casing itself if used normally. There is a recess in the knob of the thred so installing them in regular knobbies will not be possible. What happened to the bead anyway, that's strange.

I got the tire very lightly used, but the previous owner had blown the bead off the rim which wore down the rubber covering the wire bead. Long story short, it came off the rim again (I did get a season's use out of the tire), and did enough damage that it won't stay on if I inflate over 40-45 psi. Not exactly confidence-inspiring, considering I use it instead of standard tires to prevent crashes. At any rate, I know about the internal lip, but I was hoping for some way to replicate it; maybe some esoteric drill bit with a flange on the end that you shove in after drilling the main hole. I know it is a long shot, but it would be awesome if possible.

IIRC, studs are added to car tires by the tire dealer, not the manufacturer. But the tire is made to accept them. The tire dealer won't add them to a tire after it's been driven on.

Even if you do figure out a way to do this with your tire, it will probably cost more than a new tire is worth.

My 26" Nokians shipped from Finland, in 91, still have all their studs.
