If you don't run tubes or want to try without tubes first I recently was told to try 16oz of green antifreeze and one tube of Alumaseal. Mix the two together and it should be enough for two large tires. I haven't tried it but after some research it seems its been tried a lot with good results. I have also heard fabric softener, Sprite and of course Slime also work.

Slime or another brand of tire sealer was recomended to me by the sellers of my btr wheels. I got the slime but havent needed to put in in yet?

I use slime in a lot of our mowing equipment and it seems to work well but is a real mess if you have to change the tire. The other methods may be just as messy I haven't tried them but slime goes everywhere and gums up everything.
