Is a taller or wider tire better?
Wider tires perform better on dry surfaces. Dry grip and performance are generated with the footprint’s road surface contact. Since wide tires provide a larger road contact area, they are able to significantly improve its handling and maneuvering, even during their high speed applications. Wider tyres are heavier to move and will have a bigger contact patch with the road surface, resulting in more friction and energy expenditure. On the other hand, thinner tyres are lighter and have smaller contact patches, resulting in less friction and energy loss.
