Sumitomo HTR A/S P03 All-Season Tire

Sumitomo's UHAS offering in 15- to 20-inch rim sizes. Three circumferential channels evacuate water efficiently; TireDriver's instrumented test confirms above-average hydroplaning resistance and excellent dry grip, though wet lap times trail class leaders by roughly two seconds. UTQG grades are Treadwear 540, Traction A, Temperature A for the W-speed root size; H/V-speed variants may carry a different Treadwear grade. The 45,000-mile warranty is a manufacturer claim, not owner-confirmed.

Right for sporty sedan owners wanting confident wet braking (Traction A) and dry grip in a wide performance size range. Skip if you need certified severe-snow traction; no 3PMSF stamp means a 3PMSF-rated all-weather tire is the right call for hard winters.

Cured-rubber-and-steel construction; no chemical-exposure pathway in normal mounting and use, no Prop 65 warning. Tires as a class shed tire-wear particles and 6PPD-quinone in road runoff, and scrap tires are predominantly burned or downcycled, giving the category a below-average environment score.
