I am in need of replacing the tires that are currently on my 751 Bobcat. I have foamed filled tires but I want to get away them due to cost, ride, and the added weight. The majority of the time I use the Cat with tree shear to cut cedars and other trees. Questions: 1. What ply tire would be best for this operation? 2. Would a tube-less tire with green slime work best, that is- would it prevent most small leaks and could a larger leak still be plugged? 3. Would a tube-less tire without green slime work okay? 4. Would a tube tire with liner between the tube and tire work best? 5. Can you use green slime in tube tire. 6. What tread design works best for this type of application? Thank you in advance for your time. Stephen in Oklahoma
