I have a CZ 4817, and the tires are fairly old and leaky. I just deal with it by putting air in them every time I use it. I recently tried to level the deck, and found that I couldn't get the deck high enough. I set the cutting height to 3", but at the max height adjustment, the blades were lower than 3". So I'm thinking the tires may be the wrong size. By replacing the tires, I may be able to kill two birds with one stone.
What are the correct sizes?
