10 000 km update on Kumho Ecsta Sport PS72
Hi guys! As promised, here is my update on using the tyres for more than 10 000km now on my Tesla Model 3 long range.
The first thing I noticed, which has spoiled me a lot, Is how quiet and comfortable they are. They change the whole feel of the car. The previous tyres, with the same size, were the old Continental all season contact 1, which is not that bad, comfort wise, as per the reviews I've read, but the Kumho's are like magic carpet in comparison. They absorb even hard potholes with significantly less cabin noise and vibration, noticably more.
Driving on smooth asphalt, there is almost no noise from the tyres. Not sure if the foam inserts have anything to do with this, or the tread design, but they are really quiet.
Dry grip is phenomenal. I occasionally have to get home really fast from far away, so I push the car a lot, but I have never ever felt the need to slow down in a curve, even with the bad road conditions we have here in Bulgaria. The handle even dusty roads very well.
The sidewall is soft, which doesn't help with a sporty feel, but the tyres feel secure nonetheless, and I don't mind them being a little squishy, it actually makes it a bit more fun. There is no locked-in-the-center feel of the steering wheel, the steering feels great in all conditions.
Wet grip is also good, and safe. I haven't noticed anything concerning when cornering even with little puddles on the roads. Straight aquaplaning is really safe and secure. I've done it quite so many times, unintentionally, with speeds above 100kph in deeper water, the car feels stable. But maybe the weight of the car assists here.
Durability wise, I unfortunately have to drive on gravel roads daily, and not for a short distance, but thankfully the tires hold up. There are no tiny cuts or pieces falling off due to the gravel, as I've had with other tyres, specifically PS4.
The starting tread depth was around 7mm. The model 3 is mainly rear wheel drive. Today I measured them, the rears have around 5.5mm and the fronts around 6mm left after exactly 10 700km. For the price I paid for them, which is 116 euro per tyre for 235/45/18, they are a steal. I, as everyone else, wanted to get the PS5, but they cost almost 250 per tyre, for the same size. That tells you a lot.
Efficiency wise, the continental averaged 14.9 kwh/100km, for approximately 25 000km with all weather conditions, including a lot of ice and deep snow, for at least 2 months (5000km). The Kumho average 15.4kwh/100km for the past 10 700km, where at least 95% of the mileage was done on dry roads with temperatures above 10° C.
Same conditions, same temperature, same road, same distance, same speed going both ways, with the continental I was using around 12.5 kwh/100km on average, and around 14.5kwh/100km with the Kumho.
I will wait for everyone's questions before I post a review in the website as well, just to include everything else that I might have missed.
