Every Tyre. Every Tube. Tested Before It Reaches You.
Quality at Hartex is not a final checkpoint. It is built into the process — from material selection through construction to the two-stage testing procedure every product goes through before it leaves the factory. This page documents what we test, how we test it, and the standards we hold ourselves to. We publish this so you don't have to take our word for it.
Tyre Testing
We Don’t Just Inspect. We Test.
Every Hartex tyre goes through a multi-stage testing regime — covering in-process checks during manufacturing and finished product testing before dispatch. Here is what each test does and why it matters.
Why This Matters
Six tests. Each one targets a different failure mode. In-process testing catches compound issues before construction begins. Structural and performance tests catch manufacturing deviations before dispatch. By the time a Hartex tyre reaches a rider, it has been tested at every stage — not just inspected at the end.
In-Process Testing
Compound viscosity is checked during mixing using a Mooney Viscometer — ensuring the rubber formulation is correct before it ever enters the tyre.
Wobble Testing
The finished tyre is mounted and rotated to measure lateral runout. Any wobble beyond tolerance is flagged — a straight-running tyre starts here.
Static Balancing
Mass distribution across the tyre is checked. An unbalanced tyre causes vibration at speed — this test catches it before dispatch.
Endurance Testing
The tyre is run under sustained load and rotation on a test machine — simulating real-world mileage to validate durability before the tyre leaves the factory.
Plunger Testing
A calibrated plunger is pressed into the tyre tread at a defined force measuring resistance to penetration and validating the protection layer's performance.
Burst Pressure Testing
The tyre is inflated inside a containment rig to its burst pressure limit — validating structural integrity of the casing and bead at extreme pressures.
Tube Testing
100% of Our Tubes Are Tested. Not a Sample. Every One.
Why This Matters
A tube failure in the field — for export customers and OEM partners — has downstream implications for their own customers. Our 100% testing standard means every tube that leaves our factory has been individually verified, not statistically sampled.
Stage 1
Performance — air retention under load
Every tube is inflated and held for 24 hours. Any loss in air retention fails at this stage.Stage 2
Appearance and integrity — visual defects, joint quality, valve integrity
Visual inspection of 100% of tubes. Water submersion test applied to a defined percentage to identify micro-leaks not visible to the naked eye.What We Stand By
We test everything we ship. We publish what we test so you can verify it. We update our testing procedures as standards evolve. And we give our operations and QA team the final say on what goes on this page — because accuracy matters more than impressive-sounding claims.
