TUFFIOM 18x9.50-8 Lawn Mower Tires Set of 2, 4PR Turf Tire Lawn & Garden Tires, Compatible With Most Lawn & Garden Utility Vehicles, Tubeless

What It Is

The TUFFIOM 18x9.50-8 Turf Tires are a set of two tubeless replacement tires for lawn tractors, zero-turn mowers, and garden utility vehicles. They’re designed for turf-friendly traction on grass, dirt, and light gravel without damaging lawns.

Fitment & Compatibility

Before buying, confirm three things: tire size, rim diameter, and load capacity. The 18x9.50-8 size means an 18-inch overall diameter, 9.5-inch section width, and 8-inch rim. Measure your current tire’s sidewall markings—if they match, these fit. They’re compatible with most brands (John Deere, Cub Cadet, Husqvarna, Craftsman) as long as the rim is 8 inches and the tire width clears your mower deck and frame. Check the load rating: 4PR (4-ply rating) handles up to ~540 lbs per tire, fine for standard lawn tractors but not heavy commercial use. No OEM-specific; these are universal aftermarket.

Key Things to Know

• Installation: These are tubeless, so mount directly on your existing 8-inch rims—no inner tube needed. Use tire irons and soapy water; a bead seater or compressor helps set the bead.
• Tread pattern: The multi-directional turf tread provides good grip on slopes and wet grass, but avoid aggressive off-road use—they’re not for mud or rocky terrain.
• Air pressure: Run at 14–18 PSI for best ride and turf protection. Over-inflation reduces traction; under-inflation risks rim damage.
• Gotcha: Some users report slight size variance (1/4 inch) between tires—rotate them front-to-back after break-in to even wear.

Should You Buy It

If you need a budget-friendly, reliable set of turf tires for a residential lawn tractor or zero-turn, these are a solid choice. They fit most standard 8-inch rims, install easily, and offer good traction without tearing up your yard. Avoid if you require heavy-duty flotation tires or need exact OEM matching for a commercial mower.
