Kumho Ecsta V730.
The new tire from Kumho seems to fall squarely in the Enduro 200 category versus the Super 200s. It has plenty of grip, but not quite as much as the Bridgestone RE-71Rs that I am used to running on. However, the Kumhos were far more consistent for laps around the track and even on autocross.
So far, the tires have been to one autocross, where I got seven runs on them, and one track day at Laguna Seca. I was out on track for 1+40 (5 20-minute sessions), and the tires were consistent the whole day. Additionally, they didn’t experience as much wear as Bridgestone. These Kumhos will be my go-to for a set of lapping tires, and they are one of the cheapest 200TW tires in 245/40/18. I’ll explore some of the Super 200 options for autocross next year.
To the left are measurements I took for the track day and auto-cross. The tires have a new tread depth of 6.35 mm. The front tires lost about .5mm between the two events, and the rear experienced negligible tread wear. I did not rotate tires at all between the auto cross and track day.
