That is why I originally asked for tubeless. I had driven it about 50 feet or so before I realized it was flat. Drove it 50 feet back to the compressor and no valve stem.
I put tubes in all my garden tractor tires because despite having good beads etc., they just wouldn't hold air. Had tubes in for 2 years now and have yet to put any additional air in. I think garden tractor tires just aren't the quality of larger tires
