Carlisle Super Lug 20/10-8 B

What It Is

The Carlisle Super Lug 20/10-8 B is a heavy-duty, high-traction turf tire designed for zero-turn mowers, lawn tractors, and commercial mowing equipment. It’s built for performance on slopes, wet grass, and loose soil, offering deep lugs for grip without excessive turf damage.

Fitment & Compatibility

Before buying, verify three things:

• Tire size: 20/10-8 means 20-inch overall diameter, 10-inch tread width, and 8-inch rim diameter. Measure your current tire’s sidewall stamp—if it matches, it’s compatible.
• Rim width: This tire fits 8-inch diameter rims with a width range of 7–9 inches. Check your wheel’s rim width (stamped on the rim or measure inside edge to edge).
• Machine fit: Common on zero-turn mowers (e.g., Toro, John Deere, Scag, Bad Boy, Gravely) and some lawn tractors. Not universal—measure clearance around the tire well and check if your mower uses 20/10-8 as OEM or a common replacement size. Carlisle is an aftermarket brand; it’s a direct replacement for OEM tires in this size.

Key Things to Know

• Quality: 4-ply rating, bias-ply construction. Durable for residential and light commercial use, but not for extreme commercial abuse or heavy loads.
• Installation: Moderate difficulty. Requires tire irons and a bead seater if doing it yourself. Most users pay a shop $15–$25 per tire for mount/balance.
• Tread design: The Super Lug pattern provides excellent traction on hills and wet grass, but can leave more marks on delicate lawns compared to a turf-saver tire. Not ideal for fine, manicured Bermuda or bentgrass.
• Common gotcha: Some zero-turn mowers need a tire with a specific load rating or ply count. The 20/10-8 B is rated for 1,000 lbs per tire—verify your machine’s weight (with operator) doesn’t exceed this.

Should You Buy It

Buy this tire if you need reliable traction on slopes, uneven terrain, or damp grass and your mower takes 20/10-8 tires. It’s a strong value for residential and light commercial use, with a proven track record (4.8 stars from 1,100+ reviews). Skip it if you mow flat, manicured lawns and want minimal turf marking—look for a smoother tread.
