Waterfall's Eco Dynamic is an all-season tire for sedans, coupes and other passenger vehicles, offering confident handling and steering on dry and wet roads. A strengthened carcass improves its load-carrying ability.
Four broad circumferential grooves boost drainage on wet pavement, narrow lateral grooves in the shoulder blocks add year-round traction, and a five-pitch, computer-designed tread pattern lowers noise for a more comfortable ride.
The 225/40R18 size is rated 92W for load and speed. It offers 9/32-inch tread depth, a 44 psi maximum inflation pressure, a UTQG rating of 400AA and an overall diameter of about 26 inches. This size carries a 40,000-mile treadwear warranty.
