Front right and rear left tires have a slow leak. front will leak down to essentially flat in a couple days, rear leaks down to 5 psi in a week or so. More of a hassle really. I have just been bringing my Rigid cordless tire inflator each time I need you use the tractor, but that is getting old it's time to fix them. The front seems easy enough, take it off and bring it to the tire shop. But how should I go about getting the rear fixed? That one is not going to be as easy to get to the shop. What would y'all do in this situation?
