Homemade studde tyres. How?

I am sure I remember reading about peopel making homemade studde tyres by putting screws in the tyres themselves. Seriously, is this working or just a joke? How exactely is the screws put in the tyre (from the innside out or outside inn? What sort of screws?

Sounds like a puncture (or several..) to happend if you ask me, but I`d like to know.

Yeah, I've done it. Sheet metal screws, from the inside out. Use a tire liner. Be careful for the first few miles, those suckers are sharp.

If you're going anywhere near a paved surface, it's a waste of time.

For strictly off-road use, homemade screw tires can vastly exceed the traction of anything available commercially, and should last a couple of seasons.

You can get a first class Nokian winter tire for about $50 I think. How long would it take to screw in 100 screws and then glue in a liner? Sounds like a lot of work....

It takes about half an hour per tire.

I used #6 x 3/8 screws. The screws should just penetrate the tire (slightly more than does a commercial stud). Drill the knobs from the outside using a 1/16 drill bit. Screw the screws through the holes from the inside of the tire, with the heads inside. Sacrifice an inner tube for each tire to use as a heavy-duty outer liner between the screws and the working inner tube. Your LBS may generously give you a couple if you don't have any around the house at the moment. Handle with care, because once the tire is studded, it's very ouchy-making to your hands.

Two boxes of screws - $6.

I already had the knobby tires and two extra inner tubes to sacrifice as the double liner between the tube and the screws.

This is for a cheapo x-mart bike being converted to a winter rat. Cheap is the goal (except I splurged and bought a used Sram 7-speed IGH for about $180).

Keep in mind that for some of us, the MAKE philosophy trumps the convenience of store-bought.

exactely my way of thinking. Buying is no fun. Can get ok studded here for £17,- Got them for two 26" bikes and one 24" bike. Two of the tyres has lost several studs, so I think I`ll try repair job for a start.

Guess my son would like some "monster stud" ones just for fun on a spare bike.

I`we got a friend with a slim budget that need studs (car free) so I might make some for her.

Think I`we got plenty of tyres and tubes lying around.

Using a drill to screw them in should be fast.


It is not heavy / stiff with the extra tube innside?

It will be a boat anchor no matter what is inside.

In the late '80's I made some by running screws from the inside, then cutting the extra off with a side cutter right at the tire tread. I put an old foldable clincher tire in as a liner.

They were a blast!

Now I have Nokians for commuting.

The other day, out riding in the beautiful autumn sun my son said to me: "oh, uh, I am not saying that you used to be fat (the benefit of teaching them to lie at an early age) but you are getting slimmer"..

Some of those look absolutely lethal, I'd hate to come off infront of a guy using one of those.
