(2) Turf Tire Assemblies 20x10.00-8 Fits John Deere ZTrak UC30772 UC29111

What It Is

These are two complete 20x10.00-8 turf tire assemblies (rim and tire pre-mounted) designed for zero-turn mowers like John Deere ZTrak models. They replace worn rear tires that have lost traction, carry weight poorly, or leak.

Fitment & Compatibility

Before buying, verify these three things:

• Machine model: Fits John Deere ZTrak models that use OEM part numbers UC30772 or UC29111. Common compatible mowers include Z930A, Z950R, Z960R, Z970A, and Z997R. Check your owner’s manual or current tire for these numbers.
• Tire size: 20x10.00-8 (diameter 20”, width 10”, rim diameter 8”). Measure your existing tire’s sidewall markings—if it says 20x10.00-8, these fit. Do not guess based on deck size.
• Bolt pattern & hub: These are 4-bolt wheels. Confirm your mower uses a 4-bolt pattern (most ZTrak do). If you have a 5-bolt or odd pattern, these won’t work.

This is an aftermarket replacement, not OEM John Deere. Quality is comparable, but the rim finish may differ slightly.

Key Things to Know

• Quality: 4.7 stars from 3 reviews suggests solid build. These are air-filled (pneumatic) tires, not foam-filled—expect a smooth ride but potential flats if punctured.
• Installation: Easy if you have a jack and basic tools. Remove the old tire, bolt on the new assembly, and inflate to 20-30 PSI. No tire mounting needed.
• Common gotcha: The rim’s offset may differ from OEM. Check that the valve stem clears your mower’s frame or deck. If it’s too tight, you may need a 90-degree valve stem adapter.
• Pair only: This is a set of two. If you need just one, buy a single assembly separately. Mixing with old tires can cause uneven wear.

Should You Buy It

Buy these if your John Deere ZTrak’s rear tires are bald, cracked, or won’t hold air, and you want a direct bolt-on replacement without mounting tires. Skip if you need a different size, a foam-filled tire for puncture resistance, or OEM-branded parts for warranty concerns.
