The Sumitomo HTR Z5 tire comes in 275/40R18. It has a Load Index of 103 which means the tire is rated to hold up to 1929 lbs. The tire has a Speed Rating of Y so it is rated to go up to 186 mph. The tire comes in a Black Side Wall.

As with all Sumitomo tires, the HTR Z5 features an asymmetric five-rib tread pattern that offers grip, superior handling, and safety in all kinds of weather. The tread pattern rapidly sheds water to keep the contact patch on the road and the intermediate notches and center ribs keep the ride smooth while enhancing traction and handling. The Sumitomo HTR Z5 provides a 2-ply polyester casing combined with 2 high rigidity steel belts for a stronger sidewall and improved handling. This tire cannot be driven on at very low temperatures, but it is the perfect tire for all other weather demands and seasonal requirements.
