11x4.00-5" Flat Free Lawn Mower Tire and Wheel, 11x4-5 Smooth Front Tire for Zero Turn Mower with 1/2" or 3/4" or 5/8" Bearing Bore, 3.4"-7.5" Hub, 2 Pack

What It Is

A pair of 11x4.00-5" flat-free (airless) front tires and wheels designed for zero-turn mowers. These replace pneumatic front tires prone to flats, offering a maintenance-free solution for residential and light commercial mowing.

Fitment & Compatibility

Before buying, measure three things:

• Tire size: Must be 11x4.00-5 (11" diameter, 4" wide, 5" rim). Verify your current tire sidewall matches.
• Bearing bore: Available in 1/2", 5/8", or 3/4". Measure the axle diameter or existing bearing inner diameter. Most zero-turn mowers use 5/8" or 3/4".
• Hub width: The hub (mounting flange) is adjustable from 3.4" to 7.5". Measure the distance between the mower frame arms where the tire mounts. Ensure this range covers your mower’s width.

Common brands: Cub Cadet, Husqvarna, John Deere, Troy-Bilt, Ariens—but fitment varies by model. Check your mower’s manual or measure existing tire/wheel specs. Not for riding tractors with different axle sizes or deck-mounted caster wheels.

Key Things to Buy

• Quality: Flat-free tires are solid urethane/foam—no air, no flats. Ride is stiffer than pneumatic, so expect more vibration on rough terrain. The smooth tread works best on grass, not gravel or mud.
• Installation: Easy—remove old wheel, slide new one onto axle, secure with existing washer/cotter pin. No tire mounting or inflation needed. May require a spacer if your axle is narrower than the hub’s minimum setting.
• Common gotchas: The hub’s adjustable design uses set screws—tighten them firmly to prevent wobble. If your mower has a brake or speed sensor on the front axle, verify the wheel’s hub doesn’t interfere. Weight capacity is typically 150–200 lbs per wheel; check if your mower’s front end exceeds that.
• Durability: Lasts longer than pneumatic tires (years vs. seasons), but the foam can degrade in extreme heat (over 120°F) or if exposed to oil/gas.

Should You Buy It

Buy if you’re tired of fixing flat front tires on a zero-turn mower and want a no-maintenance upgrade. Skip if you need a soft ride for bumpy lawns or have a mower with non-standard axle sizes (e.g., 3/4" bore with a 1/2" axle requires an adapter). Best for flat, smooth lawns and residential use.
