RRQ 10 Inch Solid Polyurethane Tire 4.10/3.50-4 Tire, 10" Flat Free Wheels with 5/8" Bearings, 2.2" Offset Hub for Garden Cart, Hand Truck, Lawn Cart, Mower (2 Pack)

What It Is

A pair of 10-inch flat-free polyurethane tires designed to replace pneumatic wheels on garden carts, hand trucks, utility trailers, and lawn mowers. The solid construction eliminates flats, making them ideal for heavy-duty or rough-terrain use where punctures are common.

Fitment & Compatibility

• Tire size: 4.10/3.50-4 (10" outer diameter, 4.10" width, fits 4" rims).
• Bearing: 5/8" inner diameter (common for 5/8" axles).
• Offset hub: 2.2" offset – center of the wheel is offset from the hub mounting face. This affects how the wheel sits on the axle; measure your existing wheel’s offset to ensure the cart or mower frame clears the tire.
• Not a direct OEM replacement for most mowers – these are aftermarket wheels, not designed for specific brands like Toro, John Deere, or Craftsman. Check your original wheel’s offset and axle diameter before buying.
• Weight capacity: Typically 300–400 lbs per wheel (check listing detail), but verify your load doesn’t exceed that.

Key Things to Know

• No air, no flats – solid polyurethane is puncture-proof, but the ride is stiffer than pneumatic tires. Expect less shock absorption on bumps.
• Installation is straightforward – slide onto a 5/8" axle and secure with a cotter pin or clip. No tire mounting or inflation needed.
• Offset matters – the 2.2" offset is relatively deep. On some carts or mowers, this can cause rubbing against the frame or fenders. Measure your existing wheel’s offset from hub face to wheel centerline.
• Durability – polyurethane resists cracking and wear better than rubber, but can become slick on wet grass or loose gravel. Not ideal for high-torque drive wheels on self-propelled mowers.

Should You Buy It

Buy these if you need a no-maintenance, flat-free wheel for a garden cart, hand truck, or utility trailer with a 5/8" axle and 2.2" offset. They’re a solid upgrade for rough terrain but skip them if you need a cushioned ride or a precise OEM mower replacement.
