OTR stands for Off-The-Road, a broad term that covers tyres developed for applications off of paved roads, often under more rugged conditions. The OTR category encompasses activities such as earthmoving, road construction and mining. 

OTR-tyres need to perform under heavy conditions and must therefore meet high standards. Aside from BKT, Techking is another brand offering a range of radial OTR tyres with a quality that has been well-proven in practice.
