‘Track Width’ is the distance between the center line of each of the two tyre contact patches on the same axle. It is not the distance between the wheel mounting flanges.
On most vehicles, the track width will differ between the front and rear axles since they perform different functions.
A very important factor in car design is ‘Track Width’. Track width dramatically affects cornering behaviour and body roll. A larger track width will have a smaller lateral load transfer when cornering and vice-versa. Fitting different tyres will have an affect on the desired load transfer.
A car with a larger track width will be harder to manoeuvre around obstacles.
Anti-roll bars will affect the load transfer.19th September 2014
