Winning design

Our Razor wheel for Tesla is the only rim awarded with both the Red Dot and the iF Design Award. Our design philosophy is grounded in the car's design language.

EXPLORE DESIGN

Excellent engineering

We had aerodynamic efficiency in mind during the whole design process. An extensive CFD analysis by EXA / Dassault Systèmes confirm our efforts paid off.

EXPLORE EFFICIENCY

9.9%

less vehicle drag.

30%

less air moved by wheel.
Designed in Germany & Sweden.
Engineered for Electric Vehicles.

Quality manufacturing

We only work with suppliers that have their manufacturing approved by the German TÜV, something that is rare in the aftermarket wheel business. Our flow formed product line is made in Germany and Czech Republic.

Every TNA wheel type is tested by a third party laboratory and certificates are issued. For example the Chela wheel with carbon disc mounted passed over 1 800 000 cycles cornering fatigue test without issues. Basically the wheel is designed to outlive the car. All ECE and KBA/ABE certificates are conveniently available for download.
