Wheel and Tire Testing
Tire materials push the limits of standard test setups. Rubber compounds stretch to extreme elongations and change behavior with temperature, and high-strength cords are difficult to grip without breaking at the jaws. Explore our application notes to see how Instron® grips, extensometers, and capillary rheometers deliver accurate, repeatable results for tire rubber and cord.
Learn how tire rubber compounds flow during processing. This application note uses a SmartRHEO SR20 Capillary Rheometer to measure viscosity across a range of shear rates and to measure extrudate swell with a laser. The results show non-Newtonian flow behavior with good repeatability, data you can use to optimize formulations and keep production consistent.
Tire cords are very strong reinforcement materials, which makes them difficult to grip without causing premature failure. Our cord grips use smooth, curved faces that distribute stress evenly along the specimen. This reduces jaw breaks and gives you more accurate, repeatable results.
Tire elastomers stretch to extreme elongations, vary with temperature, and thin during testing, which makes accurate strain measurement difficult. Learn why clip-on extensometers fall short, and how non-contacting and long-travel extensometers, such as the AVE2 Video Extensometer and XL Series Extensometers, measure strain reliably through break. We also cover pneumatic and self-tightening grips that prevent slippage and premature failures.
