Abstract
A pneumatic tire having a tread portion with a convex profile, a pair of axially spaced bead portions, and sidewall portions extending therebetween. The tread portion is provided with a pair of circumferentially extending continuous grooves defining groove edges with a combined width of more than 16% of the ground contacting width. The tire design reduces overall tire noise, especially air resonance without deteriorating tire performance on wet surfaces.
