Had a pretty big gash on my Kubota L3750 rear tire. Had surgery on my shoulder & was unable to remove to take to shop, service truck plus cost of tire was too much, or patch/tube. Found liquiTube online, found it at a local Napa and put it in tire. Easy. Months later, still no leak. I'm sold. Going to order larger size and put in the remaining 3 plus the 4 on the MF. They sell all sorts of quantities, I got the 1 gal size, but they have 5 gal, 55 gal and much larger if needed. Dot otr approved.
