A sealant called Green Stuff Slime. It works very well. I use it with my
commercial mowers and I haven't dealt with a flat in 7 years. I bought a
Great Dane Chariot SR, the big 61" one and the previous had put tubes in
the tires. One was flat. The previous owner said they had it for 3 years
and had a flat once every 2 months. He had a lot of rocks and junk on
his property. I had the tubes removed and the tires remounted to the
rims as tubeless. Never even patched the leak with a patch. Put slime in
them and they have maintained their pressure for over 2 years. I used
these mowers every day from March to November in all kinds of conditions
and on all kinds of ground including bush hogging with it. Not one flat.
I highly recommend this green slime. It can be bought at most auto parts
stores and Wal mart, Kmart, Target and other box stores. It comes in a
clear bottle and it is truly green.

Slime didn't work for me.
