The Toyo Observe GSi-6 LS is a studless performance winter tire for passenger cars, coupes and SUVs. Its directional tread and circumferential grooves clear water, slush and snow to improve winter traction.
Large inner tread blocks sit closely together to cut noise, and a continuous rib center helps straight-line stability. The tread digs into deep snow and slush for added grip.
In the 255/55R20 size, this tire has a 110H load and speed rating with extra load (XL) construction. Specs include 12.5/32-inch tread depth, a 50 psi maximum inflation pressure and an overall diameter of about 31.02 inches. A 50,000-mile treadwear warranty applies to this size.
