Ecsta V710 radials are Racetrack & Autocross Only tires developed for drivers that want Kumho's highest level of competition performance, turn-in response and cornering traction. In addition to looking like pro-level racing slicks, Ecsta V710 tires perform like them as well, trading longevity for performance.



While Ecsta V710 radials meet DOT requirements, they are not appropriate for highway use. Ecsta V710 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 V710 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.



The Ecsta V710 tires mold a high-grip tread compound that runs with tread temperatures of between 210 and 240 degrees Fahrenheit when pushed to the limit on a dry track. This compound is molded into an asymmetric tread design utilizing a slick tread surface to maximize rubber-to-road contact and grip with just two circumferential grooves on the inboard half of the tread. Beginning with a tread depth of 4/32-inch, they will not require shaving; however, they will benefit from heat cycling before competition. The tire’s internal structure features radial construction that uses two slightly angled casing plies (with one ply wrapping around the bead and returning high up the sidewall to provide three actual sidewall plies). The belt package consists of twin, lightweight steel belts reinforced by a spirally wrapped circumferential nylon cap ply under the tread.



NOTES: Some Ecsta V710 tires featured a rounded shoulder profile and overly generous section width dimensions while others feature a squared shoulder profile and less generous section width dimensions. There is no overlap in sizes between the two designs and both share the same internal construction and tread compound.



One of the disappointing combinations we have encountered is staggered tire/wheel size applications that include rounded shoulder fronts (225/50R16) and squared shoulder rears (245/45R16). Unfortunately the "wider" rear tires don’t actually offer a meaningful increase in section or tread width in these cases. Only tire size combinations using more stagger between the front and rear tire sizes will experience a noticeable gain in rear tire width when combining rounded shoulder fronts and squared shoulder rears.



While rounded shoulder and squared shoulder tires can be combined in axle pairs on the same vehicle, some suspension tuning may be required to maximize vehicle performance when combining staggered fitments featuring both designs.



Ecsta V710 tires benefit from vehicle alignments that offer some negative camber and tires with the squared shoulder profiles will typically require more negative camber than tires with the rounded shoulder profiles.



*Specific sizes featuring rounded or squared shoulders are identified as such on the tire tire's SPEC tab.
