Tires Going Flat???

[ScottSeptic]

I have a 930 Cat Loader and the tires are a little dry rotted. They hold air most of the time but I'm getting it ready for winter and dont want to worry about them getting low on me. I was going have tubes put in them but I wasnt sure if that stuff they pump into them to seal them was better. The machine is generally used for snow and light loading. Any thoughts on which is better the tubes or the pump in stuff? Thanks:usa

Never used the goop but have had a few tire guys talk about how they hated it.
Tubes are probably cheaper and the wheels could be reused when you have to replace the tires.
