Hello X.
The thing about Slime is that you have to have it in your tires/wheels BEFORE you get a puncture. There were some older versioins of the same concept that pooled in the bottoms of your tires when they were stopped, therefore making any effort at wheel balanacing impossible. Italso voids your warranty.

I come from mesquite thorn country. Short of 10 ply Michelines, Slime or somthimg like it is the best you can do, but when you put in your tires, IMMEDIATLY do a long drive to make sure the stuff is spread around to not pool in your tires. Be prepared to have to have your tires rebalanced.

[I have known guys that drove LPG converted trucks that also used the gas to air up low tires. It made flat fixin real interesting]
