We also consulted our wheels supplier and was told that in Japan most wheels designed for truck required a special "JWL-T" standard.
Some of the wheels passed "JWL", but can't passed "JWL-T", thus restrict from selling to trucks. "JWL-T" required strength test on heavier vehicle. 3000 lbs cars vs 8000 lbs truck.
Wondering if similar test are performed ?
