(Set of Two) Hustler Flat Free 13x5.00-6 Assemblies, replaces 605038 fits Fastrak & Raptor SD 36", 42", 48"

What It Is

This is a set of two flat-free (non-pneumatic) 13x5.00-6 tire and wheel assemblies designed to replace the OEM Hustler part 605038. They are intended for zero-turn mowers like the Hustler Fastrak and Raptor SD models with 36", 42", or 48" decks, eliminating flats and air pressure maintenance.

Fitment & Compatibility

Before buying, verify your mower uses 13x5.00-6 tires (measure outer diameter and width if unsure). These fit Hustler Fastrak and Raptor SD models specifically—but not all Hustler models (e.g., Super Z or Z series may differ). Check your deck size: they fit 36", 42", and 48" decks, but confirm the wheel bolt pattern (usually 5/8" or 3/4" center hole with standard lug spacing). If your OEM part number is 605038, these are a direct aftermarket replacement. Measure your existing wheel offset (typically 2-3/8") to ensure clearance on your spindle or frame.

Key Things to Buy

• Weight & ride: Flat-free tires are heavier than pneumatics—expect a firmer ride on rough terrain. They add stability but can reduce traction on wet grass.
• Installation: Usually bolt-on with no special tools. Use a torque wrench to tighten lugs to 50-60 ft-lbs. Check for clearance with your deck lift mechanism.
• Durability: These resist punctures and UV cracking, but the rubber compound may harden over time in extreme sun. Store indoors when not in use.
• Speed limit: Flat-free tires are rated for lower speeds (under 10 mph). Avoid prolonged high-speed transport to prevent heat buildup.

Should You Buy It

If you mow on bumpy, debris-filled, or thorny terrain and hate patching tubes, these are a solid upgrade. They’re best for homeowners or light commercial users with a Fastrak or Raptor SD who want zero maintenance and no flats. If you need a softer ride or mow delicate turf, stick with pneumatics.
