18x9.50-8 Lawn Mower Tires, 18x9.50x8 Turf Garden Tractor Golf Cart Tires Set of 2, Tubeless 4PR

What It Is

This is a set of two 18x9.50-8 tubeless turf tires (4-ply rating) designed for garden tractors, zero-turn mowers, and golf carts. The wide, low-profile tread provides minimal lawn damage while offering good flotation on soft ground.

Fitment & Compatibility

• Size check: Measure your current tire sidewall for “18x9.50-8” (18” overall diameter, 9.50” section width, 8” rim diameter). Rim width should be 7-8 inches.
• Bolt pattern & offset: These are tires only, not wheels. They fit any 8” rim with the correct bead seat. Verify your rim’s bolt pattern and offset separately.
• Machine types: Common on John Deere X300/X500 series, Cub Cadet XT1/XT2, Husqvarna TS/GT series, and many golf carts (Yamaha, Club Car, E-Z-GO). Not for zero-turn mowers with 20” or larger tires.
• OEM vs aftermarket: Aftermarket replacement. No OEM-specific part number – size compatibility is the only requirement.

Key Things to Know

• Tubeless design: These are tubeless – ensure your rims are tubeless-compatible (no spoke holes or rust pits). Use a bead sealer if mounting on old rims.
• 4-ply rating: Adequate for residential use (up to ~1,000 lbs per tire). Not for heavy commercial mowing or rocky terrain. Overloading can cause sidewall bulging.
• Installation difficulty: Moderate. You’ll need tire irons, a bead breaker, and a compressor (minimum 40 PSI to seat beads). Consider professional mounting if you lack tools.
• Tread pattern: Smooth turf tread – excellent traction on grass, poor in mud or snow. Not for highway use.

Should You Buy It

Buy if you need a budget-friendly, durable replacement for your garden tractor or golf cart on flat lawns and gentle slopes. Skip if you need aggressive traction for hills, muddy conditions, or commercial duty – look for a 6-ply or knobby tire instead.
