A DIY solution for non highway use
1 TSP course ground pepper
2 TSP fine ground pepper
18 oz ethylene glycol antifreeze
It is best to break the tire bead and dump it in. If you do opt to put it in via the valve stem use a small drill bit to open the clogged stem.
Since I have discovered this I spend a lot less time on flat tires. So far I have only used it on tubeless tires. Kind of hard to get it into a tube.
Should make a video of this.
