Flat-free tire and wheel assemblies can replace compatible front wheels on a zero-turn mower without needing air inflation. Choose by the mower’s specified tire size, hub length, axle fit and load requirements, not simply by the words “flat free” or “universal fit.”
Flat-free describes the tire’s construction, not its tread: the options below include both turf and smooth patterns. A smooth tire still has friction, and “non-marking” does not guarantee that turning on soft or wet turf will leave no damage.
Measure the existing tire, hub and axle before ordering. These front-wheel assemblies are not interchangeable rear drive tires, and a matching tire-size label alone does not establish compatibility.
Best flat free tires for zero turn mowers
The three assemblies below have different dimensions and hub configurations. Compare them with the mower manufacturer’s specified replacement rather than treating them as alternatives for every zero-turn mower.
1. Marathon 30326 13×5.00-6 Flat-Free Tire and Wheel
Marathon 30326 has a polyurethane flat-free tire with turf tread mounted on a steel wheel. Its nominal tire size is 13×5.00-6; the linked assembly has a 3-inch centered hub and 3/4-inch oil-infused bushings.
Marathon 30326 13×5.00-6 Flat-Free Tire and Wheel
- Turf-tread polyurethane tire on a steel wheel.
- 3-inch centered hub and 3/4-inch oil-infused bushings.
- One assembly; verify mower fit and load rating.
This is one tire-and-wheel assembly, not a pair. If replacing both front wheels, confirm the required quantity and matching specifications before ordering.
Marathon’s size page lists an approximate outside diameter of 13.3 inches and width of 4.5 inches. Allow for the manufacturer’s dimensional tolerances and check wheel-fork and deck clearance on your mower.
There is a load-rating discrepancy for this product: the linked listing and manufacturer’s size page do not agree. Confirm the rating of the supplied 30326 assembly with Marathon before choosing it for the load your mower places on each front wheel.
Flat-free construction removes air-pressure maintenance, but it does not establish a particular ride comfort, turning performance or service life. Check the mower manufacturer’s tire requirements if a change in ride or steering is a concern.
A 3-inch hub is not a direct replacement for every wider hub. Check the complete hub and axle measurements, including the specified bushings and retaining hardware.
Use only a manufacturer-approved spacer or adapter arrangement for the exact mower and wheel. Do not improvise washers to correct an unexplained fit mismatch; select the correct assembly or ask the manufacturer.
Strength
- Polyurethane flat-free construction
- Turf tread on a steel wheel
- 3-inch centered hub
- 3/4-inch oil-infused bushings
Limitations
- Load-rating discrepancy needs confirmation with Marathon
- Fit depends on hub, axle and clearance measurements

2. Marathon 01410P 11×4.00-5 Flat-Free Tire and Wheel
Marathon 01410P is an 11×4.00-5 polyurethane flat-free assembly with smooth tread. The linked version has a 5-inch centered hub and 3/4-inch oil-infused bushings; it is supplied as one wheel assembly.
Marathon 01410P 11×4.00-5 Flat-Free Tire and Wheel
- Smooth-tread polyurethane tire on a steel wheel.
- 5-inch centered hub and 3/4-inch oil-infused bushings.
- One assembly; match the hub, axle and load requirements.
Check the exact hub configuration before comparing it with the MARASTAR below. The Marathon’s 5-inch hub is longer than the MARASTAR’s base hub, even though both carry an 11×4.00-5 size label.
Do not cut, grind or shorten the wheel hub to force this assembly into a mower fork. If the specified hub is too wide, choose a compatible replacement and follow the mower manufacturer’s installation instructions.
The linked 01410P listing gives a 300 lb load limit, while Marathon’s general 11×4.00-5 size page lists a different rating. Do not use the higher size-family figure as permission to exceed the supplied assembly’s rating; confirm the exact variant if the load requirement is unclear.
The smooth tread is a different pattern from the 30326’s turf tread. Neither pattern guarantees freedom from turf scuffing or compaction; mower weight, ground conditions and driving technique also matter.
Strength
- 11×4.00-5 flat-free polyurethane tire
- Smooth tread
- 5-inch centered hub
- 3/4-inch oil-infused bushings
- One tire and steel-wheel assembly
Limitations
- The 5-inch hub must fit without cutting or grinding
- Confirm the supplied assembly’s load rating and mower compatibility

3. MARASTAR 00232 11×4.00-5 Flat-Free Tire and Wheel
MARASTAR 00232 is a single 11×4.00-5 smooth-tread flat-free tire and wheel assembly. Its included adapter kit offers specified fit adjustments; “universal fit” is not a guarantee for every mower.
MARASTAR 00232 11×4.00-5 Flat-Free Tire and Wheel
- Smooth tread; one assembly with adapter kit.
- 3.4-inch centered hub and installed 3/4-inch bushings.
- Kit accommodates a 5/8-inch axle and specified hub configurations up to 5 inches.
- For compatible mower front casters; not for highway use.
The assembly has a black steel wheel with a 3.4-inch centered hub, installed 3/4-inch oil-infused bushings and a grease fitting. It is intended for compatible mower front-caster use, not highway use.
The supplied kit accommodates a 5/8-inch axle and specified hub configurations from 3.4 to 5 inches. Check the kit instructions, axle diameter and required spacing before choosing the setup.
The linked 00232 package contains one assembly. A two-pack is a separate purchase option; do not assume this listing supplies both front wheels.
Follow the wheel and mower instructions for lubrication. Our guide to grease-gun fittings is related reading, not proof that a particular fitting or tire assembly fits your machine.
Confirm the installed assembly’s load rating and clearance with the manufacturer if those details are missing from the selected package.
Strengths
- Smooth-tread flat-free tire
- 3.4-inch centered steel-wheel hub
- Installed 3/4-inch bushings and a grease fitting
- Adapter kit for specified alternate axle and hub configurations
Limitations
- Not a guaranteed fit for every zero-turn mower
- Check exact load rating, clearances and required quantity

Choose the correct wheel configuration first, then consider tread and ride characteristics. Flat-free construction does not remove the need to inspect the wheel, bushings and retaining hardware.
Marathon 30326 13×5.00-6 has a larger nominal tire size and turf tread. MARASTAR 00232 has an 11×4.00-5 smooth tire and an adapter kit. They are different fit options, not interchangeable choices for the same mower.
The Marathon 11×4.00-5 assembly uses a 5-inch hub. Match that dimension and its 3/4-inch bushings to your mower before considering it as a replacement.
If the fit or load rating cannot be verified, ask the mower or wheel manufacturer before ordering. Do not modify a hub to make an unsuitable wheel fit.
