Set of 2 18x9.50-8 Lawn & Garden Mower Tires,4Ply Tubeless | MOTOOS Set of 2 18x9.50-8 Lawn & Garden Mower Tires for Tractor Lawn Mower Riding Golf Carts 4Ply Tubeless

What It Is

This set of two 18x9.50-8 4-ply tubeless tires replaces worn or damaged rear or front tires on riding lawn mowers, garden tractors, zero-turn mowers, and small utility vehicles like golf carts. They provide traction and load support for general turf mowing and light hauling.

Fitment & Compatibility

Measure your existing tire sidewall – it must read 18x9.50-8. This is a common size for many John Deere, Husqvarna, Craftsman, Troy-Bilt, and Cub Cadet riding mowers, especially on rear axles.
Check the rim width – these tires fit 7-inch wide rims (most common on 18x9.50-8 applications). Measure your rim’s inner width; if it’s 6 inches or 8 inches, these may still mount but could affect bead seating or tire profile.
Verify load rating – these are 4-ply rated (typically 480 lbs per tire at 14 psi). Ensure your mower’s total rear axle weight (including you and any attachments) doesn’t exceed ~960 lbs combined.
Confirm valve stem type – tubeless design requires a compatible rim with a valve stem hole. If your rims use tubes, you can still use these tubeless tires with a tube added, but it’s not ideal.

Key Things to Buy

• Quality: 4-ply rating offers decent puncture resistance for residential turf, but not for rough terrain or heavy commercial use. Tread pattern is a basic universal rib, not aggressive.
• Installation difficulty: Moderate. You’ll need tire irons, a bead breaker (or a sturdy board and vehicle weight), and a compressor to seat the beads. Consider paying a shop $15–$20 per tire if you lack tools.
• Common gotcha: These tires arrive folded/compressed in the box. After mounting, inflate to 14–16 psi and let them sit for 24 hours to fully relax and seal. Check for slow leaks at the bead.
• Load capacity: At 480 lbs each, they’re fine for most residential riders, but heavier zero-turns with attachments may exceed that. Weigh your setup if unsure.

Should You Buy It

If you need a budget-friendly, direct replacement for worn 18x9.50-8 tires on a typical residential riding mower or garden tractor, and you’re comfortable with DIY installation, this set offers solid value. Skip if you need aggressive traction for muddy hills, commercial-grade durability, or a perfect OEM-brand match.
