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

What It Is

This is a set of two rear turf tires (20x8.00-8) with rims, designed for zero-turn mowers like the Cub Cadet ZT1 series. They replace worn or damaged rear tires to restore traction and stability on lawns and light terrain.

Fitment & Compatibility

• OEM Part Number: 634Z05924 (Cub Cadet factory replacement).
• Models: Fits Cub Cadet ZT1 42" and 46" deck models (e.g., ZT1 42E, ZT1 46E, ZT1 50E, ZT1 54E – confirm rear tire size matches).
• Measurements: Tire size is 20x8.00-8 (20" outer diameter, 8" wide, 8" rim). Check your current rear tires for these numbers.
• Bolt Pattern: Typically 4 on 4" (4 bolts spaced 4" apart). Measure center-to-center on opposite bolts or verify with your hub.
• Valve Stem: Standard rubber stem; no special adapter needed.
• Aftermarket Note: These are OEM Cub Cadet assemblies. Aftermarket alternatives (e.g., Kenda, Carlisle) may fit but check load rating (usually 300-400 lbs per tire) and rim offset.

Key Things to Know

• Installation: Moderate difficulty – you’ll need a jack or block to lift the mower, a socket set, and possibly a torque wrench (tighten lug nuts to 45-55 ft-lbs). No special tools for tire mounting (pre-assembled).
• Quality: OEM tires have a smooth turf tread that minimizes lawn damage but can slip on wet grass or slopes. 5.0-star rating from 6 reviews suggests consistent fit and durability.
• Common Gotcha: The ZT1 54" deck model may have a different rear tire size (22x9.00-10). Double-check your existing tire’s sidewall markings before buying.
• Price vs Aftermarket: At $189.98, these are ~$40-60 more than generic turf tires. You’re paying for guaranteed fit and OEM valve stem placement (no rim offset issues).

Should You Buy It

Buy these if you own a Cub Cadet ZT1 42" or 46" and want a direct, no-guesswork replacement with proven fitment. Skip if you have a 54" model or prefer cheaper aftermarket tires (e.g., Carlisle Turf Saver) that may require rim swaps or spacers.
