MARASTAR 21426 15x6.00-6 Tire and Wheel Assembly, Replacement Riding Lawn Mower Front Tire Compatible with 100 and 300 Series John Deere Riding Mowers

What It Is

The MARASTAR 21426 is a complete front tire and wheel assembly (15x6.00-6) for riding lawn mowers, designed as a direct replacement for models like the John Deere 100 and 300 series. It’s ideal for replacing worn or damaged front tires to restore steering, stability, and ride quality.

Fitment & Compatibility

Before buying, confirm your mower uses a 15x6.00-6 tire size and a 3/4” ball bearing wheel center. This assembly fits many John Deere 100 series (e.g., D100, D110, D125, D130, D140, D150, D155, D160, D170) and 300 series (e.g., X300, X304, X310, X320, X330, X340, X350, X360, X370, X380, X390). It also works with select models from Cub Cadet, Husqvarna, MTD, and Craftsman, but always measure your old tire’s diameter, width, and rim hole diameter. OEM cross-references include John Deere AM137396, AM137395, and AM137394. Deck size doesn’t matter—only front tire specs.

Key Things to Know

• Quality: Ribbed tread design provides good traction and steering on grass and gravel; no inner tube needed (tubeless). Users report long tread life and solid bead seating.
• Installation: Simple bolt-on replacement—remove the old wheel, align the new one on the spindle, and tighten the nut (usually 1/2” or 5/8”). No special tools or balancing required.
• Common gotchas: Some users note the valve stem may be positioned differently than OEM, but it doesn’t affect fit. Check that your mower’s spindle is a standard 3/4” diameter—some older models may vary.
• Price vs. OEM: At ~$45, this is significantly cheaper than John Deere branded assemblies ($60–$80), with comparable durability.

Should You Buy It

If you need a reliable, affordable front tire for a compatible John Deere 100/300 series (or similar mower), this is a solid choice. It’s easy to install, holds up well on typical lawn surfaces, and saves money over OEM parts. Avoid it only if you require a specific tread pattern or have an unusual spindle size.
