AR-PRO (2-Pack) 20x8.00-8, 20x8-8, 20x10.00-8, 20x10-8 Inner Tubes with TR-13 Straight Valve Stem - Replacement Lawn Mower Tire Tubes - Suitable for Mower/Tractor/Golf Cart/Garden Trailer and More

What It Is

This is a 2-pack of replacement inner tubes designed for lawn mowers, tractors, golf carts, and garden trailers. They hold air inside a tubeless tire or replace a worn-out tube, fitting tires with common size designations like 20x8.00-8, 20x8-8, 20x10.00-8, or 20x10-8.

Fitment & Compatibility

Before buying, match your tire’s sidewall markings: look for “20x8.00-8” or “20x10-8” (the width can vary, but the 20-inch diameter and 8-inch rim size are fixed). These tubes fit rims with a 8-inch diameter and require a TR-13 straight valve stem (included). They are not for tubeless tires that lack a rim hole for a valve stem. Check that your tire’s inner cavity is not damaged or dry-rotted—tubes won’t fix a split tire. OEM vs. aftermarket doesn’t matter; these fit any brand (e.g., John Deere, Cub Cadet, Husqvarna) as long as the tire size matches.

Key Things to Know

• Quality: Made of heavy-duty rubber; reviews note good puncture resistance, but some users report valve stem leaks over time—tighten the stem nut securely.
• Installation: Moderate difficulty. You’ll need tire irons, a bead breaker, and a compressor. Watch for pinching the tube between tire and rim; use a little soapy water on the tube to reduce friction.
• Common gotcha: These tubes are slightly oversized (to stretch into 20x10-8 tires), so they can bunch up if installed in a narrow 20x8-8 tire—inflate partially, then seat evenly.
• Double-check: Ensure your existing tire is marked “tubeless type” or has a rim hole for the valve stem. If not, you may need a different tube or rim.

Should You Buy It

Buy this if you need a reliable, budget-friendly tube for a 20x8-8 or 20x10-8 tire on a mower, tractor, or cart, and you’re comfortable with a DIY tire change. Skip it if your tire is damaged beyond repair or you need a tube for a different size/valve stem.
