While Ecsta V700 radials meet DOT requirements, they are not appropriate for highway use. Shaved or worn Ecsta V700 radials are not recommended for driving in wet conditions where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions. And like all Racetrack & Autocross Only tires, Ecsta V700 radials are not intended to be driven in near-freezing temperatures, through snow or on ice. It's also essential these tires be stored indoors at temperatures maintained above 32 degrees F.
