Quality Control

Taneisya has made efforts to accomplish competing goals for "high regidity" and "weight reduction".
In order to supply our customer with security, safety and high performance, we achieve strict JWL* and JWL-T** standards.
Additionally, Taneisya sets its own strength standard and conducts test to its wheels.
