Water is usually the best choice, because it's free (if you're drinking tap water) and has no sugar or calories. But most healthy people can get enough fluid through the beverages they consume every day. These can include water, fruit juices, coffee, sodas, iced tea, and other drinks.
A Cooper-produced non-speed rated passenger tire's maximum speed is 137 km/h. Tire speed ratings do not imply that vehicles can be safely driven at the maximum speed for which the tire is rated, particularly under adverse road and weather conditions, or if the vehicle has unusual characteristics.
Best Answer: While a Z-speed rating still often appears in the tire size designation of these tires, such as 205/40ZR17, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed. 225/50ZR16 in excess of 149 mph, 240 km/h.
