The CR227 is a Grand Touring Summer tire member of AVON Tyres' family of Original Equipment tires. The CR227 is designed to bestow comfort and confidence to the drivers of Rolls Royce and Bentley prestige sedans by providing directional stability and positive steering response in dry and wet road conditions. The CR227 is not intended to be driven in near freezing temperatures, through snow or on ice.On the outside, the CR227 features a summer tread compound molded into a six- or seven-rib symmetric tread design (depending on tire size) to provide traction, steering response and cornering stability. The tread designs were tuned to minimize road/tire noise and maximize ride comfort. The location of the wide circumferential grooves blends dry road performance with wet weather traction.On the inside, the CR227 features twin steel belts reinforced by spirally wrapped nylon that helps resist distortion at high speeds and while cornering, along with a rayon cord casing that enhances ride comfort.
