This is just my opinion but these durable, puncture free tires are a great replacement for the stock front tires on my zero turn Gravely mower. The old tires went flat and then came off the rim. They were so difficult to manage that I looked for replacements and found these perfect flat free tires. The sizing is exactly the same but you have to be careful with that as they make all sized tires to fit all axle sizes and lengths. So take a close look at the specs. These new tires are practically indestructible and really inexpensive. Love her.
