The choice of tyre width depends on the needs of the driver and the specifications of the vehicle in question. Narrower tyres improve the car's fuel consumption.
Wider tyres, on the other hand, offer better grip when cornering and shorter braking distances.
If you decide to radically change the width of your tyres, bear in mind that, according to local regulations, the wheels may not protrude beyond the outline of the car. Wing and wheel arch modifications may be necessary, so consult a professional beforehand.
