12 Inch Rear Wheel Replacement Arnold 490-324-0002 Lawn Mower Rear Wheels 12x1.75" Plastic Wheel Compatible with Craftman Push Mower Walk Behind Mowers Wagon Wheel 2 Pack

What It Is

This is a pair of 12-inch plastic rear wheels (Arnold 490-324-0002) designed for walk-behind push mowers, most commonly replacing worn or damaged rear wheels on Craftsman models and other similar mowers. They use a universal fit pattern with a 1.75-inch tire width, making them a direct replacement for OEM wheels that have a 12x1.75” size.

Fitment & Compatibility

Before buying, check these three things:

• Tire size: Must be 12x1.75 inches (12” diameter, 1.75” width). Measure your current wheel’s outer diameter and tire width.
• Axle hole: This wheel fits a 3/8-inch axle diameter (common on Craftsman push mowers). Verify your axle size with a caliper or ruler.
• Bolt pattern: The wheel has a 4-bolt pattern with 2.75-inch center-to-center spacing. Count your wheel bolts and measure across opposite bolt centers. It fits most Craftsman, Murray, and similar rear-engine mowers with that pattern.

It does NOT fit zero-turn mowers, riding mowers, or mowers with larger axles (e.g., 1/2” or 5/8”). Always cross-reference your mower’s model number with Arnold’s fitment list.

Key Things to Know

• Quality: Plastic construction is lightweight and resists rust, but it’s less durable than steel or rubber. Expect 1-2 seasons of regular use on flat terrain.
• Installation: Easy – remove the old wheel (may need a socket or wrench for bolts), slide the new one on, and tighten. No special tools required.
• Common gotchas: The plastic hub can crack if overtightened. Use hand-tight plus a quarter turn. Also, the tire is non-pneumatic (solid), so no air pressure needed, but it’s rougher on bumpy grass than pneumatic tires.
• Compatibility tip: If your mower has a different bolt pattern (e.g., 3-bolt or 4.5-inch spacing), this wheel won’t fit. Measure first.

Should You Buy It

This is a solid budget-friendly replacement for Craftsman and similar push mowers with a 12x1.75” wheel and 3/8” axle. It’s best for flat lawns and light use where rust resistance matters more than ride comfort. Skip it if you need a pneumatic tire for rough terrain or have a different axle/bolt pattern.
