LAS VEGAS, Nev. (VN) — Since Steve Hed and Zipp started beating the drum for wider road rims, a number of other wheel manufacturers have followed suit. The idea of a wider road rim is that the airflow over the tire is improved to drop the overall drag of the wheel, and bigger tires with lower rolling resistance and greater cornering grip will fit on them. The wider rim also widens the tire contact patch, reduces incidence of pinch flats, and allows lower air pressure for a smoother ride with lower rolling resistance on clinchers, and it increases the gluing area and tire retention of tubulars.
