The Sumitomo HTR T4 (High Technology
Radials, T-Speed Rated, 4-Season design) is Sumitomo Tire's Standard
Touring All-Season tire developed for the drivers of coupes, sedans,
minivans and crossover vehicles. The Sumitomo HTR T4 is designed to
combine long wear and good comfort with traction on dry and wet
roads, as well as in light snow.
The HTR T4 molds Sumitomo's fine grain carbon black tread compound
into a super computer-designed symmetric pattern that features
independent notched shoulder and intermediate blocks and a
continuous center rib to enhance operation through a variety of
weather and road conditions while delivering treadwear, noise and
ride comfort. Sipes leading into the tread block notches then
connect with four wide, circumferential tread grooves to assist with
water drainage thus enhancing all-season traction and hydroplaning
resistance.
TThe HTR T4 tires' internal structure includes twin steel belts
reinforced by Sumitomo's Jointless Nylon Band (JNB) technology
featuring spirally wound belt-edge bands to provide long-term
durability. A polyester carcass helps decrease ride disturbance to
increase ride quality.
