MowerPartsGroup (2) Turf Tire Assemblies 18x9.50-8 Fits Hustler Fastrak & Sport 784264

What It Is

This is a set of two 18x9.50-8 turf tire assemblies (rims included) designed as a direct replacement for the rear wheels on Hustler Fastrak and Sport zero-turn mowers. They’re built for residential and light commercial mowing on turf, offering better traction and reduced ground damage compared to worn or generic tires.

Fitment & Compatibility

Before buying, confirm your machine’s model and year. These fit Hustler Fastrak and Sport series (e.g., Fastrak 42”, 48”, 54”, 60”; Sport 42”, 48”, 54”) with a 3/4” diameter axle and a 4” bolt pattern (4 on 4”). The 18x9.50-8 size matches the OEM tire dimensions on most Fastrak/Sport rear wheels. Check your existing tire sidewall for size (18x9.50-8) and verify the rim offset (typically 3+2 or 3+3) to avoid clearance issues with the deck or frame. These are aftermarket replacements for OEM part number 784264, not Hustler-branded—quality is comparable, but always measure your current assembly’s overall width (8–9”) and center hole diameter (3/4”).

Key Things to Know

• Quality: Users report solid construction with good rubber compound and sealed bearings; no leaks or premature wear in light commercial use.
• Installation: Simple bolt-on swap—remove old wheel, install new one with existing lug nuts (check nut size: 1/2” or 5/8”). No special tools needed.
• Gotchas: Verify your mower’s axle keyway size (usually 3/16” or 1/4”)—these come with a keyway, but you may need a new key if worn. Also, the rim’s offset can be slightly different from OEM; measure clearance to the deck before tightening fully.
• Weight: Each assembly is about 15–20 lbs, manageable for one person.

Should You Buy It

Yes, if you own a Hustler Fastrak or Sport with worn or damaged rear tires and want a reliable, budget-friendly replacement that fits without mods. It’s ideal for DIYers who need a direct swap and don’t require OEM branding. Avoid if your mower has a different axle diameter (e.g., 5/8”) or non-standard bolt pattern—measure first.
