RONPOW 11x4.00-5 Lawn Mower Tires Flat Free and Wheel, 11x4-5 Solid Front Tires for Zero Turn Mower, 350Lbs Load, 3/4", 5/8" and 1/2" Bearings, 3.4"-5.8" Hub for Residential Commercial, 2Pack Black

What It Is

These are a set of two 11x4.00-5 flat-free (solid) tires with pre-installed wheels, designed primarily for the front caster position on zero-turn mowers. Rated for 350 lbs per wheel, they are suited for residential and light commercial use on mowers, and also fit some hand trucks or small trailers.

Fitment & Compatibility

Before buying, check these four measurements:

• Tire size: Must be 11x4.00-5 (11" outer diameter, 4" wide, 5" rim diameter).
• Bearing sizes: The wheel comes with three interchangeable bearing bushings: 1/2", 5/8", and 3/4". Match this to your mower’s axle bolt diameter.
• Hub width: Adjustable from 3.4" to 5.8". Measure your existing wheel’s hub width (the space between the mower frame brackets).
• Axle bolt pattern: Confirm the axle is a single bolt (not a pin or keyed shaft). These wheels are not compatible with spindle-mounted or two-bolt flange axles.

Common brands that accept this size include many entry-level and mid-range zero-turns from Husqvarna, Ariens, Cub Cadet, and Bad Boy, but always measure your existing wheel’s hub width and axle bolt diameter—don’t rely solely on brand name.

Key Things to Buy

• Quality: Solid rubber means no flats, but the ride is stiffer than pneumatic tires. Expect more vibration on rough lawns.
• Installation: Easy—slide onto axle, secure with existing washer and cotter pin or clip. No tire mounting or inflation needed.
• Gotchas: The hub width adjustment uses spacers; ensure you have the correct combination to avoid wobble. Some users report the bearings are not sealed as tightly as OEM, so check for smooth rotation after installation.
• Weight: Each wheel is about 5-6 lbs, noticeably heavier than pneumatic tires due to solid rubber.

Should You Buy It

Yes, if you want to eliminate flat tires on the front of your zero-turn and your mower uses a single-bolt axle with a 1/2", 5/8", or 3/4" bolt. They’re a solid value for residential use, but avoid them if you need a cushioned ride for bumpy terrain or if your axle uses a keyed shaft or two-bolt flange.
