OTR GRASSMASTER TL TURF & LAWN MOWER TIRES
Details:
The OTR Grassmaster and Grass Master TL series turf tires offer high-performance solutions across a wide range of applications, from residential mowers to commercial turf equipment. Engineered with a bias construction, these tires deliver exceptional durability and consistent performance. With tubeless capability and A3/10 speed ratings across most models, the OTR lineup supports reliable operation and smooth rides, no matter the terrain or machine.
Available in sizes from 15x6.00-6 to 26x12.00-12, this collection includes numerous load and width combinations. Smaller sizes like 15x6.00-6 and 16x6.50-8 support lighter loads (365–615 lbs) with compact section widths between 5.98" and 6.38", while larger models like 26x12.00-12 support up to 1760 lbs and offer a broader footprint with widths up to 12.6". Most tires use 4-ply bias construction, but the 26x12.00-12 also offers a 6-ply option for added strength. Max PSI ratings vary from 8 to 30 depending on size, with tread depths reaching up to 13/32 on select models like the 24x9.50-14. All rims range from 6" to 14" diameters, including wide formats like 12x10.5 and 10x8.5, designed for enhanced stability. Several models like the 25x12.00-12 and 26x12.00-12 are equipped with tire liners for extended life and improved resistance to punctures. Tread styles are labeled GRASSMASTER, GRASS MASTER TL, or GRASSMASTER WITH TIRELINER, and rim sizes are specific, such as 8x5.375, 12x8.5, and 14x7, to match the right machine fitment.
Designed for turf and R3 applications, these OTR tires are perfect for use on mowers, utility vehicles, and specialty turf equipment. Whether you need narrow, lightweight tires for maneuverability or wide, heavy-duty versions for maximum traction and support, this line offers comprehensive choices. Built for superior turf protection and consistent performance, OTR’s Grassmaster tires balance load capacity, tread grip, and comfort in every model.
Please note: Rim is not included with this product.
