I’ve never heard of that brand and I don’t think it’s sold in my area.

I’ve got a Kubota mower with a 54″ deck on which the front tires keep going flat. I THINK that happens when I mow a drainage swale around a 2-acre track and the angle puts too much pressure on the side of the tire, breaking the seal between the rim and the tire. How do I solve this problem? Maybe increase the air pressure? Buy replacement tires that don’t require air?

An image is attached the approximates the type of swale I mow.
