I installed the 235/45/18 Hankook iON EVO All Season tires on my 2022 Tesla Model 3 Performance with T Sportline TS5 18x8.5 wheels last week.
I have done a very controlled efficiency test with the tires below. The test is a 25 mile loop around our beltway that starts and stops at the same place. I record GPS time, distance, and average speed so that the test is consistent no matter what wheels and tires I have on the car.
Wheels and tires tested:
1. 20x9.0 Uberturbine wheels with factory 235/35/20 Pirelli PZ4 Tesla specific tires.
2. 18x8.5 T Sportline TS5 wheels with non Tesla specific 235/45/18 Michelin PS4S tires.
3. 18x8.5 T Sportline TS5 wheels with non Tesla specific 245/40/18(undersized diameter) Pirelli PZ4 tires.
4. 18x8.5 T Sportline TS5 wheels with brand new(<100 mile) 235/45/18 Hankook iON EVO All Season tires.
The 245/40/18 Pirelli PZ4 tires were about 1/3” undersized on the tire outer diameter so the wh/mi reading is optimistic for that tire. The car thinks it went about 3-4% further than it actually did. 220 wh/mi is a more realistic number for that tire instead of the 212 wh/mi that the trip computer said.
As you can see the Hankook tires are about 18% more efficient than the original Uberturbine wheels and PZ4 tires.
The Hankook tires were about 8%-10% more efficient than either of the 18” summer tires even though they were all on the same wheels.
I am thoroughly convinced that the efficiency claims of these new Hankook iON EVO tires are accurate. They are incredibly efficient.
These Hankook tires have a 50k mile guarantee and they have a 600 Treadwear rating on the tires.
I pumped the tires up to 42 psi as recommended and I noticed that the tire pressure didn’t change that much from that value even after extensive driving. In fact it even went down slightly in the rear tires after a drive. That is really good that it maintains a consistent pressure throughout the drive. All of the other tires would get up to as much as 46 psi after a similar drive.
I did a 220+ mile drive each way this weekend with the new Hankook tires. Going out there was a torrential rain storm for about 165 miles. This wasn’t normal rain. It was more like flooding on the interstate. I could feel the standing water causing drag on the car.
I averaged 280 wh/mi going out until I stopped to charge. However, it stopped raining and cleared up while I was charging. I averaged 226 wh/mi for the next 55 miles but that was at a slower speed going up the mountain.
Standing water on the road absolutely destroys your efficiency no matter what wheels and tires you have on the car.
Coming back home I averaged 207 wh/mi in my 2022 Model 3 Performance for 220+ miles. I had the A/C on 66 degrees F the whole time and I averaged 61.2 mph according to the GPS app.
I also was able to do 142 wh/mi for my 12 mile highway commute into work. That is at a much slower speed(~51 mph average) because of construction.
I haven’t been able to measure a difference in noise with my SPL meter. The Hankooks and the 245/40/18 Pirelli tires were measuring the same DB value. They definitely aren’t any louder but I really couldn’t tell the difference in sound. They both sound quiet to me.
I paid $1077 for the tires installed at discount tire. They price matched some random online retailer for $224 per tire.
