(2) OTR 15x6.00-6 Smooth Tires 8 Ply for Lawn Garden Tractor and Zero Turn

What It Is

This is a pair of 15x6.00-6 smooth (rib) tires from OTR, designed for lawn garden tractors and zero-turn mowers. The 8-ply rating makes them suitable for light-duty commercial or heavy residential use on paved surfaces, driveways, and manicured lawns.

Fitment & Compatibility

Before buying, verify the following:

• Size: 15 inches outer diameter, 6.00 inches width, 6-inch rim diameter. Measure your current tire – it must match exactly.
• Rim: These are tires only – you reuse your existing 6-inch rims. Check that your rims are in good condition and have the correct bead seat.
• Application: Smooth tread is best for hard, flat surfaces (concrete, asphalt, turf) – not for mud, wet grass, or slopes. Common on front wheels of zero-turns and some garden tractors.
• Brand/Model Fit: OTR is an aftermarket brand. They fit most brands (John Deere, Cub Cadet, Husqvarna, etc.) as long as the tire size matches. Cross-reference your OEM part number if unsure.
• Load Capacity: 8-ply rating supports around 500-600 lbs per tire (check specific load index on sidewall). Ensure it meets your machine’s front axle weight.

Key Things to Know

• Quality: 8-ply provides puncture resistance and longer life than 4-ply, but ride will be stiffer. Users report good durability on pavement.
• Installation: Moderate difficulty. You’ll need tire irons and a bead seater (or take to a shop). Not tubeless – requires a rim lock or tube (check if your rims are designed for tubeless tires).
• Common Gotcha: Smooth tires offer poor traction on wet grass or loose soil. If you mow on slopes or damp ground, consider a turf tread instead.
• No Rim Included: This is a common oversight – budget for rims or reuse existing ones.

Should You Buy It

Buy this if you need replacement front tires for a zero-turn or garden tractor used primarily on pavement, driveways, or flat, dry turf. The 8-ply adds durability, and the price is competitive for a pair. Skip it if you mow on wet grass, slopes, or soft ground – you’ll want a lug or turf tread tire instead.
