(Set of 2) 18x8.50-8 Tire wheel assy Ariens 07101130, Fits Ikon-X, Gravely ZTX Zero Turn Mowers

What It Is

This is a set of two complete tire and wheel assemblies (18x8.50-8) designed to replace the front caster wheels on Ariens Ikon-X and Gravely ZTX zero-turn mowers. They are commonly used for turf-friendly traction and smooth rolling on residential or commercial mowing decks.

Fitment & Compatibility

Before buying, verify these three things:

• Model fit: Confirmed for Ariens Ikon-X (42", 52", 60" decks) and Gravely ZTX (42", 48", 52", 60" decks). Not compatible with older Ikon or standard ZT models without checking dimensions.
• OEM part number: This set replaces Ariens OEM #07101130. If your mower uses a different front wheel part number (e.g., 07201130), it likely won’t match.
• Measurements: Tire size is 18x8.50-8 (18" diameter, 8.5" wide, 8" rim). Axle hole diameter is 5/8". Wheel bolt pattern is 4 on 4 inches. Confirm your existing wheel hub matches these specs.

Key Things to Know

• Quality: These are aftermarket assemblies, not OEM Ariens/Gravely. They use a standard 2-ply turf tire and painted steel rim. Expect similar durability to OEM but not identical rubber compound.
• Installation: Direct bolt-on, no modifications needed if fitment is correct. You’ll need a 9/16" socket and wrench to remove the retaining nut and washer. Torque to 40-50 ft-lbs.
• Common gotcha: The valve stem orientation may differ from OEM. You might need to rotate the tire on the rim to align the valve stem for easy air access.
• Weight capacity: Each assembly supports up to ~400 lbs static load. Fine for most zero-turn mowers but not for heavy commercial use with frequent bouncing.

Should You Buy It

Buy this if you need a direct replacement for worn or damaged front caster wheels on an Ariens Ikon-X or Gravely ZTX and want a cost-effective aftermarket option. Avoid it if you require OEM-specific tread pattern, higher load capacity, or your mower uses a different axle size (e.g., 3/4" hole). For the price, it’s a solid value for light to moderate residential use.
