Are there god tires out there?

I bought this Husqvarna (YTH22V46) 3-4 years back. I’ve been upgrading it where possible to keep it running for as long as possible (actual wheel bearings vs bushings, no flat tires on the front, upgraded blades/spindles, etc). My only issue now are these rear tires. No matter what I do I seem to constantly end up with them flat. I have plugged them when there are holes, but it seems like a never ending battle. Are there any other type of tires out there that are more durable?
