PROPARTS Set of 2 18x9.50-8 Lawn Mower Tires 4PR 18x9.5-8 Tractor Turf Golf Cart Tire for Lawn & Garden Mowers 18x9.50x8 Tires, Tubeless

What It Is

This pair of PROPARTS 18x9.50-8 tires is designed for ride-on lawn mowers, garden tractors, and turf vehicles that need a wide, stable footprint. They’re tubeless and rated for light-duty turf use, not for heavy off-road or commercial mowing.

Fitment & Compatibility

Before buying, confirm your current tire size is exactly 18x9.50-8 (also stamped 18x9.5-8 or 18x9.50x8). Check the rim width: these tires fit rims 6–8 inches wide (most common on garden tractors). Measure your tire’s height and width to ensure clearance under the fender and deck. They fit many brands (John Deere, Cub Cadet, Husqvarna, Craftsman, Troy-Bilt), but always verify by model number—some zero-turns use odd sizes. OEM replacements are fine; these are aftermarket but meet 4-ply (4PR) load specs.

Key Things to Know

• 4-ply rating means moderate puncture resistance for turf and gravel, but not for rocky or muddy terrain.
• Tubeless design requires a good bead seal on the rim; check for rim rust or damage before mounting.
• Installation is DIY-friendly with basic tire tools; you may need to deflate and soap the bead. No balancing needed for lawn use.
• Common gotcha: these are slightly wider than some OEM tires, so measure your mower’s axle-to-fender clearance (at least 1 inch) to avoid rubbing.

Should You Buy It

If you need a budget-friendly replacement pair for a standard garden tractor with 18x9.50-8 tires used on flat lawns or gentle slopes, these work well. They’re not for heavy loads or aggressive traction, but for light-duty mowing and turf protection, they’re a solid value at $65.
