I have a JD 265 with tubeless tires.  Last year, every week, I had to add air to the front tire.  Now the back tire has the same problem.  I haven't inspected the tires or the rims yet but was wondering what I should do.  Should I get a tire sealant or anything to reseal around the rim?  Should I install inner tubes?  The tractor is probably close to 15 years old and don't want to spend a lot of money.

Thanks Mike
