Slime 30015 Inner Tube for riding lawn mowers, ATVs, quads, tractors and farm/agriculture equipment, Extra Strong, Includes Self-Sealing Slime Sealant, Heavy Duty Replacement, 16x6.5-8" / 16x7.5-8"

What It Is

The Slime 30015 is a heavy-duty replacement inner tube designed for riding lawn mowers, ATVs, tractors, and farm equipment. It includes pre-installed Slime sealant to self-seal punctures up to 1/8 inch, reducing flat tire downtime.

Fitment & Compatibility

• Tire size: Fits 16x6.5-8 and 16x7.5-8 tires (common on zero-turn mowers, garden tractors, and utility vehicles).
• Valve stem: Straight rubber valve stem; check clearance if your rim has a deep center well.
• Bead and rim diameter: 8-inch rim diameter required. Not compatible with 15-inch or 10-inch rims.
• OEM vs aftermarket: Universal fit, no brand-specific mount. Works with most riding mower brands (John Deere, Cub Cadet, Husqvarna, etc.) as long as tire size matches.
• Check before buying: Verify your tire sidewall stamp (e.g., “16x6.5-8”) and inspect rim for rust or damage that could pinch the tube.

Key Things to Know

• Sealant included: Pre-filled with Slime sealant. Activates upon puncture; no need to add extra. May dry out after 2-3 years—replace tube then.
• Installation difficulty: Moderate. Requires removing tire from rim, inserting tube, and reseating bead. A tire spoon or pry bar helps. Consider professional mounting if you lack tools.
• Weight: Heavier than standard tubes due to sealant (about 2.5 lbs). Not an issue for mowers but may affect ATV balance slightly.
• Common gotcha: Over-inflation or pinching during install can cause premature failure. Use a tire lubricant and follow max pressure (typically 10-12 PSI for lawn mowers).

Should You Buy It

Buy this if you want a durable, self-sealing tube for a 16x6.5-8 or 16x7.5-8 tire on a riding mower or ATV, and you’re willing to do a moderate DIY install or pay for mounting. It’s a solid upgrade over basic tubes for puncture-prone areas, but if you need a tube for a different size (e.g., 20x8-8), look elsewhere.
