I’m doing this from a computer and trying to get Tapatalk to load pics so bear with me please.


Something that 90% of us have had to do, vulcanize a tire. The closest place to me that does it is 1.5 hours away and they close at 5 which means I’d have to take off work, go up there, then take off another day to go get the tire once its been fixed. Well I cut one back at Hale mtn in October, cut the living shit out of it. With the way work has been I didn’t have time to be running all over east tn so I was just going to run the spare and deal with it. A buddy showed me the cold vulcanizing compound from busted knuckle’s website. I thought hell I’ll try it whats the worst that’s going to happen. I ordered the smaller container of the compounds, the grinding disk that Burkey used and waited. I watched the video of Burkey doing it and thought hell let’s do it. I will try to post the facebook video Burkey did but I’m not 100% sure how. Maybe Matt or someone can do it.

you don’t need the grinding wheel, but it helps. You could probably use a flap wheel or a rock but it made the job super easy.

First thing is you grind out the hole making a V groove on the exterior of the tire. I took a small die grinder and a cookie wheel and smoothed the inside up some too. This is the part that made me the most nervous but it came out ok.

Next you take the cement compound and spread it on the hole and around the edges on BOTH sides of the tire. Use this a little more liberally than you think, the compound WILL NOT stick where the cement is not. I used an acid brush that comes with most differential set up kits. Q tips didn’t hold up\

Next take equal parts of the two compounds and begin to kneed them like dough. This part sucks, this shit is NASTY for about 4-5 minutes, then all at once it starts sticking to itself. Once all the grey/white is gone and you have a completely black ball of rubber you’re good to go.

Start from the outside of the tire and begin pushing the rubber through the hole. The part that sticks through on the inside of the tire fan it out on the inside of the tire to sandwich the hole between the compound. Smooth it up with your fingers the best you can and build it up a little more on the outside.

The compound has to set up, the instructions recommend 24 hours at 60 degrees. I snuck mine into the house and asked forgiveness, maybe find a better way, that did not go well.

After its set up it will be a little soft. I took a cookie wheel and smoothed up the edges and cleaned it up since this was my first time doing it and it looked a little rough.

Hopefully this helps someone not have to run all over to get one vulcanized. It’s messy but it beats driving all over creation.

I feel the tires perform best at what can best be described as the jiggle equivalent to that of a middle aged mother of two's ass. Just right.  Cougar

The cement you spread around. Make sure to use a little more than you think you need.

I smoothed it up and made it look way better after it set up.

$25 each? they are about bald and all have been vulcanized ha.

Shit work real well. Rode on it at RBD and drug it on a rock or two and seemed to hold up. If it fails i'll re do it now that I kinda know what i'm doing.

Thanks for making the post. This stuff is magic! Though everytime I start kneading the two compounds together I think for a second Oh crap this stuff is never going to come off of my hands, then 4-5 minutes later it magically starts only sticking to itself and comes off your hands. I've fixed a ton of RZR tires with this stuff. I don't even take the tire off the wheel and it still holds up..... shit

Yeah I had a panic moment too. Even had someone else read the instructions to make sure I didn't miss something.

I read this, "This kit will do multiple large offroad repairs that are normal to see in rock crawling" but in your opinion how many tires would 1 of these kits repair?  I know it all depends upon the size of the holes, but just wondering if this is a one use and it's gone kit.   Dunno

Hell, I guess if they'll patch those 54's, they'll be OK on my 37's then!

Gregg,
This is what Matt told me "The small kit should plug around 10 holes at least like the ones in the post, and it has a 2 year shelf life as long as you seal the cans back up each time (they are like paint cans)."

So it's a "use what you need" type kit?  That is awesome and everyone should have one of these in there boxes.  What is the curing time before airing up?  Does this stuff heat up to actuate like true vulcanizing?

Yes. That's so why I had to sneak it in the house.


In the post I used way to much. I wasn't sure how much to use since it was my first time and I could have easily done 2 maybe 3 holes with the amount i got. Live and learn I guess. This stuff is amazing. We are going to try it on a backhoe tire when it warms up some.

I'll try and get some pictures of what this stuff looks like if I can make it to the shop tonight.
