I took my zero turn mower in 3 weeks ago to the dealer I bought it from. I wanted to get it serviced for this spring and if it needs any warranty work it could be done. I figured January is the best time. I had them put 2 new knobby tires on the drive wheels last year. One developed a leak last fall. I told them about it when I took it in 3 weeks ago. He called yesterday and told me my mower is ready to be picked up. I asked him if they found the leak and he responded no the transmission wasn't leaking. I said no I mean the tire. He said no we didn't see any nails so we just filled it with slime. I told him I could have done that and to break the tire down and get that slime out of there, and check the tire in a tub of water. I know what slime does to rims. I'm not at all happy.
