Hello. I could really use some help and some advice from everyone here. I live in Nevada and I have about an acre and a half to mow. I had been doing it by hand but I just got my Cub Cadet 50 inch. Well almost all my land was short except for a field in the back that had never been done before. About half an acre. The stuff was dry, very dry and about a foot and a half tall. So mower cut it nicely but parts of it were very thick but the mower did a great job. When I got done I parked my mower and cleaned it up and all was fine. About two hours later all my tires were flat. All four of them. I did some research and I guess in an area like mine it's common to get flat tires. We have nasty goatheads but not as many as we used to and the dry weeds I cut are very stalky and can be short. You walk on them and you feel the crunch. So I did more research and some people use slime, slime tubes, fill the tires with foam, buy used airplane tires, metal wheels and the list goes on and on. I only want to handle and fix this problem once. You would think you could buy tires that are thorn proof but I have not seen that. Any advice will be greatly appreciated as coming out to four flats can be pretty frustrating! Thank you all for any help.
