In both road and rail vehicles, the wheelbase is the distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is defined as the distance between the steering (front) axle and the centerpoint of the driving axle group.
Keeping this in view, what is a vehicle's track width?
In a vehicle with two axles, this is expressed as "front track" and "rear track". However the front wheels and/or rear wheels on either side of a vehicle do not necessarily have to be mounted on the same axle for the distance that they are apart to be called the "track".
How do you measure wheel track?
Wheel track is the distance measured across an axle from the centre line of one tyre tread to the centre line of the opposite tyre tread. The fitting of aftermarket wheels to your vehicle may result in the vehicle's wheel track being altered.
How big is a car?
The standards state any vehicles more than 4.7 m (15.4 ft) long, 1.7 m (5.6 ft) wide, 2 m (6.6 ft) high, or with engines larger than 2000 cc are what is called "passenger size vehicles". This regulation also mandates that all passenger vehicles cannot exceed 5 m (16.4 ft) length or 1.8 m (5.9 ft) in width.
