What It Is

This is a 12x10.5 inch steel ATV/RTV mower wheel rim designed for zero-turn mowers, garden tractors, and compact utility equipment. It’s a direct-fit replacement or upgrade for machines requiring a 5-lug pattern on a 4.5-inch bolt circle with a 4.75-inch backspace.

Fitment & Compatibility

Before buying, check these four measurements:

• Bolt pattern: Must be 5-lug on a 4.5-inch circle (5x4.5). Common on many zero-turn mowers (e.g., some Gravely, Hustler, Scag, Toro) and compact tractors.
• Backspace: 4.75 inches. Measure from the mounting pad to the inner rim edge. Too little backspace can rub frame/steering; too much may hit spindles or calipers.
• Rim width: 10.5 inches. Verify your tire bead width (typically 10–11 inch tire) and clearance inside the mower deck or frame.
• Center hole diameter: Not listed—measure yours. If too small, the rim won’t seat on the hub. If too large, you’ll need hub-centric rings.

Check your mower’s owner manual or existing rim for these specs. This rim is aftermarket, not OEM, so confirm offset matches stock.

Key Things to Know

• Material: Steel rim—durable but heavier than aluminum. Expect ~15–20 lbs per rim. Fine for lawn use but adds unsprung weight.
• Installation: Simple bolt-on if specs match. Use a torque wrench (typically 50–70 ft-lbs). No special tools needed.
• Tire mounting: Requires tire machine or manual effort. Balance beads or stick-on weights recommended for vibration-free ride at higher speeds.
• Gotcha: Only 1 review (5-star). Limited real-world feedback. Measure twice before ordering—returns may cost you shipping.

Should You Buy It

This rim is a solid choice if you need a steel replacement for a zero-turn or compact tractor with a 5x4.5 pattern and 4.75-inch backspace, and you’ve verified all fitment specs. It’s not for standard lawn tractors (usually 4-lug) or heavy commercial use where aluminum weight savings matter. If your measurements match, it’s a budget-friendly, direct-fit option.
