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.
Not sure it fits? Call the shop: 216-202-4802 — chances are we'll know it on sight.

About this tire
The OTR GrassMaster is a turf-style tire in the 18x9.50-8 size, made for riding mowers and utility machines running on grass. The lower-profile tread grips the lawn without chewing it up, and the compound is built to wear longer through the season.
This is a 4-ply tubeless tire with a 17.8 inch overall diameter and a 9.25 inch section width. It mounts on an 8x7 rim. Check your current size and ply rating before you order so the new tire matches the wheel.
OTR is our value brand, so think of this as a reliable everyday turf tire at a fair price. Sold individually and priced per tire. Choose your quantity at checkout.
