TYK Industries 6.00/6.90-9 Inner Tube Pair for Forklift & Trailer Tires — JS2 Bent Metal Valve Stem, Ozone-Resistant Butyl

Two TYK Industries 6.00/6.90-9 (21x8-9) inner tubes with JS2 bent metal valve stems made for forklift and industrial trailer tires. These replacement inner tubes come as a pair and are engineered for common industrial wheel sizes — 6.00-9, 6.90-9 and 21x8-9. Built from ozone-resistant butyl rubber and finished with a bent JS2 metal valve stem, they are factory test-inflated so you receive ready-to-install tubes. Designed for forklifts, warehouse equipment and light trailers, these tubes focus on longer air retention, puncture resistance and secure valve attachment for reliable operation under industrial conditions.

How are these tubes built to last under heavy use?

TYK Industries increases tube durability by using a thicker grade of butyl rubber and refined vulcanization around the valve area. The materials resist ozone and slow air migration, while factory inflation checks confirm each tube holds pressure before packing.

• Up to four times thicker rubber than standard inner tubes for better puncture resistance
• Ozone-resistant compound to limit aging and cracking
• Factory inflation tested to ensure air-holding performance on delivery

What makes the JS2 bent metal valve stem beneficial for forklifts?

The JS2 bent metal valve simplifies access when wheels are tight or recessed and creates a durable seal that withstands vibration and load. A valve lock nut is included to secure the stem and enable safe, lower-pressure operation when needed for traction.

• Bent metal stem improves pump access in confined wheel wells
• Strong vulcanized seal reduces risk of valve leaks
• Valve lock nut helps prevent loosening under vibration

Will these tubes fit my equipment and which tires are compatible?

These multi-fit tubes are intended for tires sized 6.00-9, 6.90-9 and 21x8-9, which are common on forklifts, pallet trucks and some light trailers. Confirm your tire sidewall size before ordering to ensure proper match; tubes must correspond to tire diameter and width range for safe inflation and seating.

• Compatible sizes: 6.00-9, 6.90-9, 21x8-9
• Common use: forklifts, industrial equipment, light trailers
• Sold as a pair for replacing both sides or keeping a spare on hand

What warranty and quality checks are included with purchase?

TYK Industries provides a three-year warranty covering manufacturing and workmanship defects. Each tube is inspected and inflation tested at the factory, so you receive tubes that are ready to install and backed by a warranty for manufacturing faults.

• Three-year warranty on manufacturing and workmanship
• Pre-shipment inflation test to verify integrity
• Quality control includes valve-area vulcanization checks

These TYK inner tubes are best for technicians, fleet managers and operators who need dependable replacements for everyday industrial use. If you run forklifts, warehouse machines or light trailers with 6.00-9 / 6.90-9 / 21x8-9 tires and want thicker butyl construction, bendable JS2 valve access and factory-tested readiness, this two-pack offers a practical solution. Keep a set in inventory or replace worn tubes to reduce downtime and improve tire performance in routine material-handling operations.
