Wally, I have a set of those coming, but I reckon I'll fit screws to one centre block in 4 so I can climb.
Liking teh use of latex in that link to cover over the studs on the inside of the tyre.
I'll still be trying out the trusty gaffer/duct tape.
Word of warning , it has taken 2 hours to drill and then screw 120 screws and my hands hurt. Glued them in and now applying punture proof tape. Ok that's not working tape/glue/tyre will not bond. So I will let glue dry and insert with the tube - as normal.
cut down the screws using a cable cutter
you did WHAT!
God just killed a kitten for you.
I used
2 cheapest nobbly tyres I could find in town. £16.99 each
2 boxes of 2.5x16mm turbodrive screws. £1.50 each
electric drill with 1mm drill bit
electric screwdriver with PZ1 bit
I've not used any protective strip between the tyre and the innertube and after a short test ride they're still holding air.

Cool, it's a homebrew tyre frenzy!
Ballsof cottonwool, I'd at least bung some duck tape in there, given all the problems the OP had with punctures.
Had a proper thrash round the woods last night, and they seemed to be working lovely, although it has to be said the people I was riding with didn't have any studs and they were doing fine too.
I still managed to fall off a couple of times, once after my front wheel dug into a concealed hole... and I landed in some yellow snow. 🙁
What kind of tyre preasure is everyone running? After inspiration from this thread, just made some from some old Tioga DH's. At the moment running them pretty firm but just wondering how low i can go before it all goes wrong!!!!
ant, i reckon that the woods isn't the place that they'll show there best qualities. i definitely could have done with a set on my ride home last night - came off twice on polished ice on roads and now have a massive bruise on my thigh to show for it...
Anyone have any bright ideas about converting tubeless tyres without having to re-fit new ones. I have been wondering whether it would be possible to fit some king of carpet-strip-type thing to the existing tyre. Can anyone think of anything else that might work as a spikey strip which can be secured to the exisiting tyre?
I think ballsofcottonwool has used the same Halfrauds tyres that I have used. They even have an "insert screw here" type mark in the tread block. Mine have been going with no problems - or offs (yet...) all this week.
About 35 psi here, for a 12 stone bloke with 5" forks. I wouldn't want them to squirm around too much though.
I'm running at 35psi. Tyre pressure seems to be a fine balancing act with grip varying greatly at different pressures. Because my screws are outside the central rolling strip, changing the pressure affects the amount of contact they are making with the ground.
Cycling with non studded pals has demonstrated there is little or no difference in grip for a studded versus non studded tyre in snow; it's on the ice and compacted stuff where the difference is.
My diy spiked tyres held air without any protection between the tyre and tube over a 2 hour ride in the woods last night. They studs didn't make any difference as the snow was soft and a foot deep. They were reassuringly sure footed on the very hardpacked snow on the roads. I think I'll switch back to my regular wheels while the snow is still soft as they are 600g lighter each due to being having lightweight tubeless tyres as opposed to Halfords puncture resistant monsters.
All done

gone for many tiny tips. Getting tape to stick inside was a nightmare. In the end rubber glued in old tube and held in place for an hour or two with an inflated tube to dry and hold.
This took too much time really. I do not recommend it.
Still - I did spend only about £20.
I'm with Ton on this one. I'd been thinking along the lines of chains rather than studs - the studs things looks like far too much work to me! Ton's solution of short chain lengths and zip ties should be quick and easy. Chances of getting a puncture on these frozen ice n snow roads are really very low.
This is my effort. Approx 54 3.5mm x 20mm diameter screws. These add approx 30-40g per tyre, if anyone cares about that.

I've aimed for about 1-2mm above tread level for them when cut down.

Since I run tubeless, I'm going to let the tubeless solution do any sealing that might be needed.
I'll fit them later and give some feedback along our 5day compacted ice road that has had cars sliding quite happily.
Well, here's my hurried attempt, about 10 mins work for a doubling of traction on hardpacked snow and ice.

i have just been out for a spin on the stiffee with a pair of newly SPIKED 2.1 advantages.
they look like ice speedway tyres.......lethal.
fantastic in deep snow and on ice and compressed snow.
a bit sketchy on the road bits.
the chains on the 29r are better on the road but spikes are better offroad.
After a little trial and error down my road, theres definitely more grip down the road than without studs. I think I need a denser pattern though. I feel there could still be more grip.
Air losses seem to be no greater than doing a normal tubeless setup so far!
I spent two hours this morning putting 60 3.5 x 20mm screws into a pair of old Nobby Nics. I cropped the exposed part back to about 3mm and covered the heads of the screws with three layers of gaffer tape.
I had a two hour spin this afternoon and everything held up OK. There is definitely loads more grip. It will be interesting to see how long they last.
If anyone has a couple of old tyres and some screws I recommend they give it a go.

111 screws in the rear Crossmark, 3 layers of Duct tape and the front Surley Endomorph dropped down to 6psi.
Wish me luck for tomorrow mornings local ice ride.
Here's mine. Grip brilliantly on ice. Rolling resistance and noise levels are somewhat high!

ScienceOfficer: I was pretty smug running Schwalbe Snow Studs tubeless, but they don't have holes through them! Are you saying you're successfully ghetto tubeless with [b]screws through your tyres[/b] !?!?!?
Wow, how did you get them up? Do you have a compressor? How much fluid did you put in? I'm impressed!
Cheers, al.
Allan,
Yes I have a compressor for first inflate - it makes things much easier.
I'm not running ghetto really - Stans flow rims which hold tyre beads very nicely, but the tyres are non-tubeless, and I don't need a rimstrip for this particular pair.
Also, I only took them to about 22 psi, at which point I could see solution around a couple of the screws. If I'd have pumped them up too high, there would probably have been latex spewing everywhere, but since there was only enough pressure to force it to migrate down the hole it was fine.
Tubeless solution is, after all, exactly for this purpose.
They're off the bike again now, since I felt they needed more studs, which I'm part way through, but I'll post up about keeping air when they're back on.
I ran mine with an inner tube at 30psi without any problems on this mornings 2 to 3 hour flat towpath and cyclepath ride.

The Surley Endomorph up front at 6psi helped as well.
just done 2 hours on mine.
no problems at all, even ok on tarmac.
spiketastic 😉
Just popped into the local diy store and brought a load of 6 x 5/8's screws. However have screwed a few in place and they're looking a tad on the thick side...Anyone else used 6 or should I be better going for 3.5's???
No punctures today. Painfully slow to make but confidence inspiring on compacted snow, ice and wet roots.

Loads of tiny studs off centre made tarmac roads no problem and lesson danger of real damage to flesh. I had one brown trouser moment as I realised I was whizzing 80 yet to be filed down screws very close to my face whilst adjusting SS alignment last night - Wally.
200 3.5x12
Managed another two hours on mine today. Fine on everything except deep, loose, powder snow. The 'off-centre' studs make road-work not [i]too[/i] noisy, but it does compromise the grip on ice a bit.
That might be it for this year, as it's raining outside and 2 degrees

john, winter does not end the second week in january......
most of the snow we get in the uk is in feb/march. 😉
OOh, now where did I put those old tyres ?
Right, I'm going to spike some Conti Twisters for the Pompino. I'll cut the bead off some slick things lying in the tyre pile for a liner. Should be a laugh, and it might get an outing at Puffer.
Cheers, al.

Ton,
John & I live in the Merseyside area. This was the worst they had seen in 30 years, it usually misses us.
will try and post a piccie after I'm done mine - 2x conti vert pro with 200 12mm screws! Wife going out shopping so perfect opportunity! 😈
Tried mine out on Sunday Night (puffer training) and worked a treat, No,6 1/2" wood screws on the outer knobs of an old conti vert,used an old inner tube glued to the inside as a liner.
Superb grip on ice, puffer should be intresting with these jolly jobbers 😉
Made mine on Friday night, ready for Sat AM ride:

Pair of old 2.1 Panaracer Trailblasters, 200x15mm + 75x12mm screws, and way too much spare time 😀 I lined them with about four layers of gaffer tape, but after about four hours of riding, one pinch-flatted. On inspection, almost every central screw-head had 'burst' through the tape and marked/pinched the tube to some extent. One obviously pinched it all the way through. Reckon some additional DPM, an old (extra) inner tube, or a strip of non-descript, tough, flexible plastic would make them perfect.
They were alarmingly effective, and dealt especially well with compacted snow on steep tarmac climbs. Also good at picking up leaf-litter 😀
Puffer's going to be deadly with all these James Bond knives-on-my-wheels set ups!
They make my Snow Studs look like children's toys...
Cheers, al.
Well, after a ride this morning where the farm roads are sheet ice, I found the limit of the Snow Studs - there's no centre studs and even with the pressure right down there wasn't much grip. So, I've put together some minimal DIY jobs anticipating the same at Puffer. Conti Gravity 2.3 tyres.
I marked the knobs with red marker pre-fitting, so they're easy to spot in the pictures below! I taped a screw to the drill and bore through from the outside-in onto a block of wood first, then from the inside-out through the holes. Clipped right down with Park wire cutters. Lined with Slime tyre liners.
I'll have a ride later but they seem good. I've no intention of going fast on these, so I'm not bothered about the lack of side-spikes. Only 22 per tyre, I'll probably double that if my test ride's encouraging.

Had a blast again on my jolly jobbers tonight, again outstanding grip on the ice, looking forward to the puffer with hopefully minimum falls and the smug smile that my ice tyres only cost me two boxes of No 6 1/2" screws 😆
You know , I dont really come on here very often . But get this .
I also remembered a mag article from , I reckon 20 yrs ago , about ice riding on frozen lakes . It was Joe breeze . Anyway , i forget the details , but they had panhead sheetmetal screws through the studs, I do remember that much .
So ,after 20 yrs of praying daily for suitable conditions here in the frozen north , on saturday I also screwed some self tappers into an old set of tyres . To keep it real and true as I could to the article I dug out my flourescent legwarmers , and not only used a 20 yr old pair of tyres , but also a 2o odd yr old old bike . The screws were new . Sue me .
If you was to redirect your internet browser device to youtube, a popular video hosting site , and search for 'spikeybike1' , 2 , 3 ,4 5 ... etc . You could view the result of my endeavors .
I should point out that it took me in the region of 4 hrs to stud my tyres . And I'm a construction worker .
thankyou .
it took about 2.5 hours to put a total of 96 screws into each of mine and cut them to the desired length with a dremmel.
Now I've doubled the number of screws they do grip rather well.
muddyfox courier.........I should point out that it took me in the region of 4 hrs to stud my tyres .[b] And I'm a construction worker[/b] .
that's where the problem lies 😀
how many cups of tea did you have in that 4 hours!
😆
I was out tonite again just for a final fettle with the bike before the puffer and still amazed with the grip,
5hrs work, 2 old tyres, 2 old inner tubes as liners, 2 boxes of screws and gaffer tape.
Big smiles if this works for the puffer 😉
OK , well , I'm booking 4 hrs to the job .
It didnt actually take[i] 4 hrs .
We'll call it a day .
Saturday's time and half. So that's 12 hrs then.
In fact I didnt actually stud the tyres at all , what I did was use a special contractors only grip snow compound on the treads .
it's only available to the trade . You've gotta be qualified an all that .
Yea .
And then there was the scaffolding .
It's all special order stuff .
Have you got yer PASMA ? CSCS ?
I can't let you on site.
Rules is rules .
I'm not making this up as I go along .
I'll see if I can squeeze you in around April , May .
This is not gonna be easy .
I can see a few problems .
I'll need a payment up front for the materials.
Did you use an RSJ up there,Mr fawlty ?
2X4 eh ? ....
Hmm ,( rubs chin) ,punctuation around those last two words. That'll cost yer .No ,
I drink coffee
You may poke fun at my construction workers moral code.
However.
Reading a number of posts it seems one or two have been predrilling their knobs before screwing with less than perfect results.
Oh dear oh dear.
A construction worker ( such as myself ) ,would not bother with any knob pre-drill japes and would simply use a self drill screw and ram it sraight through using a professional quality , hi torque , battery drill from the likes of Hilti.
Or maybe De walt .
All the best deals are on Hilti at the minute though, it seems .
It' all Black and Decker inside the casing . I digress.
His screws ( he would be male ), would not therefore push back into the tyre as the thread would bite strong into his knob ,and would find their own thread as he forced them manfully ,wilfully ,ramming them homo.
I am also ,as a construction worker of many years experience , deeply saddened at the total lack of double entendres in this thread.
I'm thinking words such
as 'stud ' , 'screw ' , 'screwing', 'knob', 'knobs','drilling ' ,and of course 'fisting ' could have been used to much comedic effect.
Yours etc etc
