OH YEA ! They did-like it for two reasons ...
First , its messy when the tire is wore out and all over the rim so much so that the rim has to be hosed off between tires .
Second , any flat tire repairs don't happen , there-for cutting into the tire repair Dollar !
I was out bush-hogging small (2-3") Locus trees when we first bought this place . When I came out from lunch one of the front tires was flat , so off it came and to Co-op it went. I expected a patch bill from the tire guy , but instead got a new tube bill . When I asked the feller about it he says "I quit counting holes at 14 !
The next morning after an afternoon of more bush-hogging , both front tires were flat . I had the co-op tire guy mount the tires tubeless and put 6oz's of snot in each of them in place of patching or tubing and didn't have another flat for years ! .
That "Snot" comes in two kinds , "Tube" and "Tubeless" , I believe the only difference is the size of the particles that do the hole-plugging ??? .
You can't use it in the new "Sensor" tires . Wal-mart sells it , and Tractor Supply too.
