MARASTAR 21425 15x6.00-6 Tire and Wheel Assembly, Replacement Riding Lawn Mower Front Tires Compatible with 100 and 300 Series John Deere Riding Mowers, 2 pack

What It Is

The MARASTAR 21425 is a 15x6.00-6 tire and wheel assembly designed as a direct replacement for the front tires on riding lawn mowers, specifically tailored for John Deere 100 and 300 Series models. It comes as a 2-pack, ready to bolt on for front-end support and steering.

Fitment & Compatibility

Before buying, verify these three things: tire size (must be 15x6.00-6), bolt pattern (typically 3/4-inch center hole with a 4-inch bolt circle, but measure yours), and hub width (check if your mower uses a 1-inch or 3/4-inch wide hub – this assembly uses a 1-inch hub). It fits most John Deere 100 Series (e.g., D100, D110, D130, D140, D150, D160, D170) and 300 Series (e.g., X300, X310, X320, X330, X340, X350, X360, X370, X380, X390, X394). Not compatible with 200 Series or zero-turn models. If your mower uses a 3/4-inch hub, you’ll need a spacer or a different assembly. Always cross-reference your OEM part number (e.g., John Deere GY20786, GY20952) with MARASTAR’s list.

Key Things to Know

• Installation is straightforward – just remove the old tire, slide this on, and tighten the spindle nut. No tire mounting or balancing needed.
• Tread pattern is smooth – these are front tires, so aggressive turf tread is unnecessary; they roll easily and minimize lawn damage.
• Quality is solid for the price – 4.7 stars from nearly 9,000 reviews indicates consistent fit and durability, though some users note the rubber is slightly harder than OEM, which can reduce traction on wet grass.
• Check your valve stem orientation – the assembly comes with the valve stem pre-installed; ensure it doesn’t hit the spindle or frame during turns.

Should You Buy It

Buy this if you need a reliable, drop-in front tire replacement for a John Deere 100 or 300 Series rider and want to avoid the hassle of mounting tires yourself. It’s a great value at $80.99 for a pair, with proven performance from thousands of buyers. Skip it if you have a 200 Series, zero-turn, or a mower with a 3/4-inch hub – you’ll need a different assembly or spacers.
