Kumho Ecsta V730

test on sunny afternoon at Sepang Circuit, track surface temperature over 40 °C. Dry grip is very good; the tire was progressive during the limit and can endure 3–4 hot laps before starting to lose grip due to overheating. Wear is just okay. Tires pricing are quite good, at least 30–40% cheaper than the competitors like the AD09 or RS4 or Z3. Loud tire rolling noise on rough road surfaces. I have no idea about its wet grip, never drive it in the rain. But from what I saw on the tire tread, it focused on dry only, not wet, damp maybe ok.

First time buying these couple of years ago and match with Ultralegerra wheels 18x9 +35 offset it was perfect not too out bit to In sits perfectly on the fenders front and back , now forward to 2022 brand new Lexus GS I have brought another set with a new wheels 18x9 Enkie cause the Advan is out of stock so I can’t wait any longer ,I did purchase then Enkie PF01 18x9 all around , it sits perfectly without any tire lips sticking out now ,I do have Bridgestone WS 60 sits a bit stretch but well everyone likes it , I even had a guy ask me how it’s done , I said simple 18x9 with 245/40/18 Bridgestone snow tire , looks sexy, I can say , so Kumho V730 can go up to 165 mph if you have enough power yes this is the tire , track days or daily , the more the tires heats up the more grippy , just be careful doing 80 mph on wet corner roads it might not be the same outcome , but dry yes it can do 100- on corners like you’re on rail , AAA I personally Recommend this than other pricey brand first , Thank you for you’re time,

i drive roughly 800km a week and these are excellent tyres when you decide to put it through its paces. lovely for spirited driving, stuck at 70-90km/h when wet. predictable grip and tyre does allow you to turn in tighter when need arises.

The most grip I have ever experienced. Great tire

Completed 2 days of 24 Hours Of Lemons in the US up in Thompson's CT. Track is a 1.7 mile on course with some tight turns and a few long areas to stretch the legs out. The car, bone stock 1989 ford Mustang. First impression was that they look great. They are said to be a "Cheater slick". On friday we tested with some worn out falkens, and just before the end of testing we sent a driver out to warm up and cure the new V730s for 10-12 hrs before the race. This was my first time trying to apply some tire curing methods (which i think helped for this kind of tire). The next day saturday, a couple drivers went out and ran on the tire, bled off the couple extra psi over 38psi. I skipped one driver change during the hottest portion and my driver expressed some over-steer/skating feeling. Looking at the tires are the end of the day they have a bit of blistering on the center rib on one inside edge. Not all the way around but just a little bit. The PSI was over 41 psi, so i think the blistering was from that. After that driver another hoed in for the day and the tire temp and pressure leveled off at 38. Day time temps were about 86*F with a clear sunny day. Day two of lemons, Rotated the front to rears, my tire growth was about 10psi from 29psi cold to 38-39 hot VS, what i thought might be about 7psi the previous day. The Tires did great all day, the outside temps about 86*F again with some clear and some cloud cover, but hot and humid. The tires performed well, although we added the swaybar in the rear to loosen the mustang up. The loose factor lended itself to some more wheel spin for a loose feel. I think this helped cause the tires to heat up more. My drivers would express a "greasy" feeling. When i got in the car at the last stint after a hot long day, i could feel the tires give way when really hustling and aggressively driving the car. When they felt off, i would scale back a bit to try to let the tires cool. This seemed to help the tires cool a bit so I could go and a attack for a few laps. With that said, i never ran a full slick all day, but i suspect that these V730 "Cheater slicks" act just like a true slick. When you get them real hot they will get greasy, but if you scale back a bit they will come back and you can attack again. For two 8 hrs of racin on a hot day, i think they performed well. They do not "talk" to you. Very low audible tone. Gotta drive by the seat of your pants to feel what they are doing. But all my drivers expressed that they could feel when the tires were saying. The mustang weighs in at 2750 with 175 lbs driver and half a tank. Big heavy car with a big v8 engine up front. A couple of my less experienced drivers locked up the brakes and flat spotted the tires. I think we were able to round out the tires while spinning the tires. Tear wear looks fantastic again for what seems to be a soft 200 TW tire and after 16 hrs of racing I suspected more wear. Will see if they last a whole other race weekend. If they do, i think they are a great, cheap, 200TW "Cheater slick". PS. A few showers showed up while i drove. I had never driven the mustang in just damp conditions. so the oil and drops of rain made for no confidence. But thats is not to say of the V730 can perform well in the rain. It is rated A for weather (I believe) with some deep grooves for water shedding. Not sure if the tire is made with silica for enhanced water/pavement adherence. So i can not at this time suggest that they are good in the wet condition.
