The Goodyear Tire & Rubber Company has developed and is testing a custom-engineered non-pneumatic (airless) tire (NPT) to support Starship delivery robots.

Starship Technologies, a Goodyear Ventures portfolio company, builds and operates a network of over 1,000 last-mile autonomous robots that carry and deliver packages, groceries and food directly to customers, Goodyear says.

To address Starship’s request related to tire health and maintenance, Goodyear said it developed a specially engineered airless tire designed to extend tire life and reduce maintenance activities for Starship’s delivery fleet.

Goodyear and Starship have entered an in-field testing phase at Bowling Green State University to evaluate vehicle and tire dependencies, the company said. Early on-vehicle tire testing data has shown positive results with respect to treadwear, braking and vibration dampening.

“Our delivery robots make thousands of deliveries every day in all types of weather conditions and terrain,” said Siim Viilup, mechanical engineering manager, Starship Technologies. “To make sure we can keep up with the growing demand for our services, we need tires that are reliable and keep our robots on the move around the clock and around the globe. It’s great to see these new tires offering reliability as well as cost savings as we scale our business.”
