It was bound to happen eventually, but I got a nail stuck in the rear tire of my tractor. The tires are filled with RimGuard and I assume no tube (I'll call the dealership this week to verify). As it is right now, there is no liquid leaking from around the nail. When I park the tractor, I make sure the nail is on the top. What is the best way to repair this? I can't take the tire off and bring it to a repair shop so my options are have a tire guy come to my shop or fix it myself. Can these tire be repaired using a plug like a vehicle tire? How hard will it be to do it (I've never actually plugged a tire but have seen it done many times and it seems like there is a lot of muscle needed)?
