GICOOL 12 Inch Rear Wheels for Arnold 490-324-0002, Replacement 12x1.75" Plastic Wheels for Lawn Mowers, 1/2" Axle Bore, 2-Pack

What It Is

This is a set of two 12-inch replacement wheels designed for lawn mowers, specifically compatible with the Arnold 490-324-0002 wheel assembly. They are intended for push mowers, self-propelled mowers, or tow-behind lawn sweepers that use 12x1.75" plastic wheels with a 1/2" axle bore.

Fitment & Compatibility

Before buying, verify these three measurements:

• Tire size: Must be 12x1.75" (12" diameter, 1.75" width). Measure your old tire’s sidewall.
• Axle bore: Must be 1/2" (12.7mm). Use a caliper or drill bit to check your mower’s axle diameter.
• Hub design: These are plastic wheels with a solid hub—no ball bearings or grease fittings. They fit mowers that use the Arnold 490-324-0002 OEM wheel, but may also work on other brands (e.g., MTD, Craftsman, Yard Machines) if axle and tire size match.

Common mowers using this size include older push models with 12" rear wheels and some tow-behind lawn sweepers. Always measure your current wheel – brand/model lists are often incomplete.

Key Things to Know

• Material: Hard plastic with a smooth tread. Good for flat, dry lawns; less traction on wet grass or slopes compared to rubber tires.
• Installation: Easy – remove the old wheel’s retaining clip or cotter pin, slide the new wheel on, and reinstall the fastener. No tools beyond pliers or a screwdriver typically needed.
• Durability: Plastic won’t rust or rot like rubber, but can crack if you hit curbs or large rocks. They’re lightweight and won’t add much weight to the mower.
• Gotcha: The 1/2" bore is a tight fit on some axles. If the wheel is hard to slide on, lightly sand the axle or bore with fine grit sandpaper. Do not force it.

Should You Buy It

If you need a direct, budget-friendly replacement for a worn or broken 12x1.75" plastic wheel with a 1/2" axle and your mower doesn’t require heavy traction or off-lawn use, this 2-pack is a solid choice. It’s best for flat, dry lawns and light-duty mowers. Avoid if you need rubber tires for grip or a different axle size.
