PowerSmart 22 in. 170cc Self Propelled Gas Lawn Mower Rear-Wheel-Drive, 3-in-1 Mulch/Bag/Rear Discharge, Steel Deck, 6 Height Adjustment,

What It Is

This is the complete wheel and tire assembly for the PowerSmart 22 in. 170cc self-propelled rear-wheel-drive lawn mower. It’s designed for replacement or upgrade on that specific model, not for other brands or deck sizes.

Fitment & Compatibility

• Exact model match: Only fits PowerSmart 22 in. 170cc self-propelled mowers with rear-wheel drive. Check your mower’s model number (e.g., PS22SP, PS22SP170) on the underside of the deck or near the handle.
• Deck size: 22-inch deck only. Not compatible with 20-inch or 21-inch models.
• Drive system: Rear-wheel-drive specific—front wheels are different. Verify you’re replacing a rear wheel.
• Measurements: Confirm wheel diameter (typically 8-10 inches) and axle hole size (usually 5/8 inch or 3/4 inch). Measure your existing wheel before ordering.
• OEM vs aftermarket: This is an OEM-style replacement, not a universal fit. Avoid generic aftermarket wheels—they won’t match the hub pattern or drive gear.

Key Things to Know

• Quality: Steel deck and wheels are durable for residential use, but the plastic hub caps can crack if over-tightened. Use hand-tightening only.
• Installation: Moderate difficulty—requires removing a cotter pin and washer. No special tools needed, but the drive gear alignment is finicky. Watch a YouTube video for your model.
• Common gotcha: The self-propel drive gear is molded into the wheel. If the gear is stripped, the whole wheel must be replaced. Check the gear teeth for wear before buying.
• Price point: At $315, this is the complete mower, not just wheels. If you only need a wheel, look for a cheaper individual replacement part.

Should You Buy It

Buy this if you need a complete replacement wheel for your PowerSmart 22 in. 170cc rear-wheel-drive mower and your existing wheel is damaged or the drive gear is stripped. Skip it if you have a different model or need only a tire—individual tires are cheaper and easier to swap.
