(Set of 2) 4.10/3.50-4 (10") Flat Free Tires and Wheels/Sawtooth tread, 4-1/4" Hub with 3/4" bore. Compatible with Toro 105-3471, Time Cutter Z, and John Deere

What It Is

This is a set of two flat-free 10-inch tires and wheels with a sawtooth tread, designed for zero-turn mowers like the Toro TimeCutter Z and select John Deere models. They eliminate flats by using solid foam instead of air, ideal for rough terrain or debris-heavy properties.

Fitment & Compatibility

Before buying, confirm three things: wheel diameter (10"), hub size (4-1/4"), and bore (3/4"). These match OEM Toro part 105-3471 and fit most Toro TimeCutter Z models (e.g., Z4200, Z5000 series) and John Deere Z-Trak 700 series. Measure your existing tire’s outside diameter—4.10/3.50-4 means 4.10" wide, 3.50" sidewall height, 4" rim—and ensure the sawtooth tread won’t interfere with deck clearance (check for at least 1" of gap). Not for lawn tractors or push mowers; verify your axle length can accommodate the 4-1/4" hub depth.

Key Things to Know

• No maintenance: Flat-free means zero air pressure checks, but they’re heavier (approx. 8 lbs each) and can make the ride stiffer.
• Installation: Typically bolts directly to existing axle with a single 3/4" bore and cotter pin. No special tools needed, but you may need a jack to lift the mower.
• Tread pattern: Sawtooth provides good traction on grass and light dirt, but can leave marks on concrete or sensitive turf—avoid tight turns on pavement.
• Weight & speed: Heavier than pneumatic tires; may slightly reduce top speed or acceleration on older mowers. Check that your mower’s drive system can handle the added rotational mass.

Should You Buy It

Buy these if you’re tired of fixing flats on a zero-turn mower used in rocky, thorny, or construction-heavy yards. They’re a solid upgrade for Toro TimeCutter Z or John Deere Z-Trak owners who prioritize durability over ride comfort. Skip them if you mow mostly smooth lawns and want a softer ride—pneumatics are lighter and smoother.
