* load capacity increases in direct proportion to the enclosed air volume.
* lower profile tires must be accompanied by wider sections or offset by stronger and more expensive construction techniques.
* At a given load capacity, if a tire is widened, it's contact patch widens, however the contact patch becomes proportionately 'shorter.'
* The wider tire may exhibit higher cornering grip, however, may give up some braking grip.
* The wider tire is more prone to hydro-planing unless aqua-channels are engineered into the tread design to compensate.
