These were good. Easy on and they held air. One month in and they are still holding air. So far so good. If something changes I will update the review.

Exact replacements for the original smooth front tires on our Snapper ST50 zero turn mower. The grooved tires make the caster wheels operate much more smoothly. They pivot without digging up the lawn.

Great

Tires look great. Quality seems good. Price was great. No complaints with the product. A little struggle to mount these 4-inch tires, but that was expected and it actually went better than I thought it would.But the Amazon packaging was crappy! These two somewhat heavy tires were packaged with a box of lightbulbs and a few other small items with no packing materials. the lightbulbs were loose inside the package and the lightbulb box was crushed. They survived since they were led bulbs. I guess we're saving the planet with no protective packing materials, but I was disappointed they would cut corners like this!

On a tire of this small size, the 4 ply is a great durability/strength feature, but makes installation very difficult, even for a good small engine & mower repair shop.
