May need to shim them due to the width of the hub.
Great zero turn front tire replacement, may have to shim one side.

No more flats!
No more flats! I used to replace the pneumatic tires a couple of times a year., After a couple of years the sidewalls would break down. These fit quickly on the same axles. The tire width is slightly smaller but doesn't cause a problem.Should have done this long ago

Good quality
These rims and tires work great on my leaf wagon i pull behind my mower. Great fit and easy install.
User
Worked flawless
Bought these because my old 1979 rear engine snapper needed new tires. The price of the air up tires was staggering! Read where someone else used them from the reviews and decided it was worth a shot! Perfect fit. And now I do not have to worry about tire pressure on the front anymore!

Flat free tire
It was not a perfect replacement for my existing wheels. A little modification was required to fit them on my gas air compressor from Northern Tools

Weak
Terrible product, used on a finish mower. The first one became "flat" because, undisclosed in the description, storing something with weight on the assembly is not recommended. So after replacing another conventional tire and wheel with this one and using the mower the "flat free" tire came loose from the wheel. Maybe good for a hand truck or something that weighs less than 25 pounds but not for a finish mower.
User
Very good
I bought just one to replace a flat on my zero turn mower. After a few weeks with no issues I bought the second tire. The second one was through Deals and had a big discount. I took a chance, and what I got was a brand new perfect tire. Real happy with the tire and the price.

Super great
Finally, a tire I don't have to replace. No more Pneumatic.... EVER
