Kumho Tire launches two new EV tires

May 13, 2024

Kumho Tire U.S.A. has launched two new additions to its EV tire range: the Majesty 9 Solus TA91 EV and Crugen HP71 EV.

The Majesty 9 Solus TA91 EV, equipped with Kumho Tire’s proprietary K-Silent technology, is designed to reduce cabin noise and enhance comfort, and the company says it’s suitable for EV coupes, sedans, and CUVs. The Crugen HP71 EV, on the other hand, is designed to provide a quiet and comfortable ride for CUVs and SUVs, with an added emphasis on all-weather performance.

The new Majesty and Crugen tires also incorporate technology to reinforce structural rigidity, which can enhance vehicle stability, improve rolling resistance performance to minimize power consumption and optimize tire contact with the road for even wear.

EV tires, according to Kumho, have different requirements than tires designed for vehicles with internal combustion engines. They need to handle the load distribution and treadwear from high torque motors and heavy batteries, and they require maximum noise reduction, as road noise can be more noticeable without a combustion engine. Kumho Tire’s K-Silent technology, which features sound-absorbing foam material inside the tire structure and a tread pattern designed to help dissipate noise, addresses these needs.

The Majesty 9 Solus TA91 EV and Crugen HP71 EV tires also contribute to improved driving range per charge. The Majesty 9 Solus TA91 EV achieves up to a 19% reduction in rolling resistance, and the HP71 EV up to a 24% reduction over the previous generation product. Both tires come with a 50,000-mile treadwear warranty.

Kumho Tire’s EV tire lineup is currently compatible with five EV fitments in North America, and the company serves as an OE supplier for manufacturers including Kia and Hyundai. Globally, Kumho Tire offers 11 total OE fitments. The Majesty Solus TA91 EV tire is available in 18- to 21-in. tire sizes, and the Crugen HP71 EV tires are available in 19- to 22-in. tire sizes.
