2-Pcs 5.70-8 5.00-8 Lawn Mower Tire Inner Tube 5.70/5.00-8 Inner Tube | 500-8 570-8 Tube JS2 Bent Valve Stem

What It Is

This is a set of two inner tubes sized 5.70-8 and 5.00-8 (interchangeable), designed for lawn mowers, garden tractors, and small utility trailers. They replace a punctured or leaking tube to restore tire air retention.

Fitment & Compatibility

Before buying, confirm your tire’s sidewall markings: this tube fits any tire labeled 5.70-8 or 5.00-8 (also listed as 500-8 or 570-8). It is not a direct fit for 4.80-8, 4.10/3.50-4, or 13x5.00-6 sizes. Check your original tube’s valve stem type—this tube has a JS2 bent valve stem (90-degree angle), so ensure your rim hole accommodates a bent stem (most standard rims do). Measure the rim diameter: 8 inches. No OEM or brand-specific restrictions—works with any mower using these tire sizes (e.g., Craftsman, Husqvarna, John Deere, MTD).

Key Things to Know

• Quality concerns: With a 3.0 rating and only 2 reviews, some users report valve stem leaks or thin rubber—inspect carefully before installation.
• Installation difficulty: Easy if you have tire irons and a compressor; tricky if the tube shifts inside the tire. Use a little air to shape the tube first.
• Bent stem gotcha: The 90-degree stem may not clear some tight rim openings or fender brackets—test fit before inflating fully.
• Valve core: Confirm the stem accepts a standard Schrader valve core (most do); if it’s defective, replace the core (not the whole tube).

Should You Buy It

This is a budget-friendly option for replacing a worn or flat tube on common 8-inch mower tires, but the low rating and few reviews suggest potential durability issues. Buy only if you need a quick, low-cost fix and can tolerate possible valve stem problems—otherwise, consider a higher-rated tube from a known brand.
