What is the maximum allowable difference in wheelbase from one side of a vehicle to the other?

The maximum allowable difference in wheelbase from one side of a vehicle to the other is no more than one inch. This regulation is in place to ensure the vehicle's handling and stability are not compromised. A significant discrepancy in the wheelbase can lead to uneven tire wear, handling difficulties, and enhance the risk of losing control of the vehicle.

A smaller tolerance, such as one inch, helps to maintain proper alignment between the front and rear axles, providing drivers with better control and a safer driving experience. In vehicle inspections, adherence to this standard is crucial for ensuring that vehicles remain roadworthy and can operate safely under various driving conditions.
