Keep getting flat tires

[Tractor Seabee]

So theres more to it than just matching these numbers?
Rear: 24x12.00-12
Front: 16x7.50-8

If you live West of the Rocky Mountains look for a Les Schwab Tire store. They can fix you up and you get to see them before you pay Mounting is always free. They can match up rims also. My BIL swore on them for tires from cars to his combines and every thing in between. I do the same.
