(2-Pack) RRQ 15x6.00-6 Inner Tube, Premium Natural Rubber, Replacement Lawn Mower Tire Tubes, 15x6x6 Heavy-Duty Inner Tube, for Riding Mower, Tractor, Golf Cart, ATVs and More (TR-13 Straight Valve)

What It Is

This is a 2-pack of heavy-duty 15x6.00-6 inner tubes made from premium natural rubber. They replace worn or punctured tubes in riding mowers, garden tractors, golf carts, and small utility vehicles (ATVs/UTVs) that use 15-inch tires with a 6-inch rim.

Fitment & Compatibility

Before buying, confirm these three things:

• Tire size: Must be 15x6.00-6 (15" diameter, 6" width, 6" rim). Some brands also label this as 15x6.0-6 or 15x6x6.
• Valve stem: TR-13 straight valve (standard for most riding mowers). If your machine uses a 45-degree or TR-87 bent valve, this will not fit without adapter.
• Rim width: Works with 6-inch rims, but check your rim’s actual inside width. Some deep-dish or offset rims may require a shorter valve stem.

Commonly fits: John Deere, Cub Cadet, Husqvarna, Troy-Bilt, Craftsman, and most universal riding mowers with 15x6.00-6 front tires. Not for zero-turn mowers with smaller 13x5.00-6 or 11x4.00-5 tires.

Key Things to Know

• Natural rubber vs butyl: Natural rubber is more puncture-resistant and flexible in cold weather, but may degrade faster if exposed to UV or ozone. Store indoors.
• Installation difficulty: Moderate. You’ll need tire irons, a bead breaker (or brute force), and a compressor. Pinch-flatting the tube during install is the #1 mistake—use soapy water on the tube before seating.
• Heavy-duty rating: These are thicker than OEM tubes. Expect a slightly stiffer ride, but better resistance to thorns and sharp debris.
• Valve stem length: TR-13 is about 1.5” long. If your rim has deep recesses, you may need a valve extender.

Should You Buy It

If you have a standard riding mower or garden tractor with 15x6.00-6 front tires and need a reliable, budget-friendly tube replacement, this is a solid choice. The natural rubber offers good flexibility and puncture resistance, and the 2-pack covers both front tires. Avoid if your machine uses bent valve stems or very deep-dish rims.
