Your upgraded wheel and tyre setup is generally acceptable provided that:
The tyres remain fully covered by the mudguards or mudflaps
The modification does not significantly alter the vehicle’s overall height
There is no tyre rubbing, excessive protrusion, or compromised handling
When choosing new rims or tyres, consult a reputable tyre specialist to ensure the fitment matches your vehicle’s specifications. A properly planned upgrade can improve driving confidence, while an unsuitable setup can negatively affect braking performance, ride comfort, and safety.

JPJ and the Royal Malaysian Police (PDRM) routinely carry out enforcement operations against unsafe and unauthorised vehicle modifications. According to the Road Transport Act 1987, if you are caught driving a vehicle with unapproved modifications, the penalties can include:
First offence: A fine of up to RM2,000, imprisonment of up to 6 months, or both
Subsequent offences: A fine of up to RM4,000, imprisonment of up to 12 months, or both
