TRIPOWER 18x9.50-8 Lawn Mower Tire – Tubeless, Fits Riding Mowers, Turf-Safe, Heavy Duty 4PR, Tire Only (No Rim), Set of 2

What It Is

A set of two tubeless 18x9.50-8 turf tires designed for riding mowers and lawn tractors. The 4-ply rating and ribbed tread pattern provide low ground pressure for turf-safe operation while handling heavier loads.

Fitment & Compatibility

• Size requirement: Your mower must use 18x9.50-8 tires (18" diameter, 9.50" width, 8" rim). Measure your current tire sidewall to confirm.
• Rim compatibility: Fits standard 8" diameter rims with 4" bolt pattern (most common on riding mowers). Verify rim width – typically 7" to 8" wide rims work.
• Brand/model notes: Direct replacement for OEM tires on John Deere, Cub Cadet, Husqvarna, Craftsman, and MTD models with this size. Not for zero-turn mowers with 18x9.50-8 tires that require a different tread pattern.
• Check before buying: Measure your existing tire’s overall diameter (should be ~18") and rim width. Ensure your mower’s axle clearance can handle the 9.5" width. No valve stem included – you’ll need to reuse or buy separately.

Key Things to Know

• Installation: Requires tire mounting tools (tire irons) and a tire machine or manual effort. Not a quick swap – budget 30-60 minutes per tire if you’re experienced.
• Tubeless design: No inner tube needed, but the rim must be clean and free of rust for a proper seal. Use bead sealer on the rim edge if needed.
• Turf-safe tread: The ribbed pattern minimizes lawn damage compared to aggressive knobby tires, but it offers less traction on wet grass or slopes.
• Durability: 4-ply rating is standard for residential mowers. Not for commercial use or heavy loads (e.g., towing trailers). Expect 2-3 seasons with normal use.

Should You Buy It

If you need a reliable, affordable replacement for worn-out 18x9.50-8 turf tires on a standard riding mower, this set delivers solid value. It’s ideal for homeowners who want turf-safe traction without paying premium brand prices. Skip it if you need aggressive off-road grip or commercial-grade durability.
