Even when a size fits your model, it's not always 100% — machines vary by year, trim, and past tire swaps. Before ordering, double-check the size on the tire that's on your machine now, or your owner's manual. And if it's still wrong, our 30-day fitment guarantee has you covered.

About this tire
The OTR GrassMaster is a turf-style tire in the 18x8.50-10 size, made for riding mowers and utility machines that work on grass. The tread is shallower than a lug tire so it grips without tearing up the lawn, and the rubber compound is mixed for longer wear.
This is a 4-ply tubeless tire with a 17.7 inch overall diameter and an 8.42 inch section width. It mounts on a 10x7 rim and carries up to 780 lbs at 10 mph. Confirm your size and ply rating before ordering.
OTR is our value brand, so treat this as a dependable everyday turf tire rather than a premium one. Sold individually and priced per tire. Pick your quantity at checkout.
