(2) Turf Tire Assemblies 20x8.00-8 Fits Cub Cadet ZT1 42" 46" 634Z05924

What It Is

This is a set of two (2) 20x8.00-8 turf tire assemblies designed for zero-turn mowers, specifically the Cub Cadet ZT1 series with 42" or 46" decks. They replace worn or damaged rear tires on residential/commercial mowers, providing traction and flotation on grass without damaging turf.

Fitment & Compatibility

Before buying, verify these three things:

• Model/Deck Size: Fits Cub Cadet ZT1 42" (model 17AHA2BZ712) and ZT1 46" (model 17AHA2CZ712). Not for ZT2 or ZTX series without checking.
• OEM Part Number: Cross-references to Cub Cadet OEM #634Z05924. If your mower uses a different OEM number, these may not match the hub pattern or wheel offset.
• Measurements: Tire size is 20x8.00-8 (20" outer diameter, 8" wide, fits 8" rim). Check your current tire sidewall for this exact size. Rim bolt pattern is 4 on 4" (4 lug, 4" center-to-center). Measure your existing wheel bolt pattern before ordering.

Key Things to Know

• Quality: These are OEM-equivalent assemblies with pneumatic tires (not solid foam). Users report good tread life and even wear, but avoid over-inflation (max 20 psi) to prevent turf damage.
• Installation: Moderate difficulty. You’ll need a jack, socket set, and torque wrench (lug nuts should be torqued to 50-60 ft-lbs). The assembly comes pre-mounted on the rim, so you just swap the whole wheel.
• Common Gotchas: The valve stem is angled—make sure it faces outward after installation for easy air access. Also, the wheel offset is 3.5" (center of rim to mounting surface). Check your old wheel’s offset; mismatched offset can cause rubbing or poor tracking.
• Set of Two: This price covers two assemblies, not one. Verify you need both rear tires (most ZT1s do).

Should You Buy It

If you own a Cub Cadet ZT1 42" or 46" and need a direct OEM-replacement rear tire set, this is a solid choice—decent value, good fit, and no adapter hassles. For other zero-turn brands (e.g., John Deere, Husqvarna), skip it unless you’ve confirmed the bolt pattern and offset match.
