I bought a brand new 2018 Hyundai i30 SR Premium 1.6 turbo with 7-speed DCT transmission. Absolutely fabulous car except for the crap Hankook 225/40R18 tires which came as standard, so the first thing I did was to do a lot of research to find a better tire. I already had experience with Michelin Pilot Sport 4 tires in 245/45R18 on my previous car and even though they were a fabulous tire, I felt I needed a change. The Asymmetric 3 tires kept appearing in reviews as being a very good tire, and so, with much thought, I decided to buy them. At first I was very disappointed with them. They simply didn't seem to suit the car. Their side walls felt too soft during hard cornering, so I started experimenting with tire pressures. In the meantime, I had travelled about 200kms on them and while the vehicle manufacturer recommended 33psi all around, this pressure in the Asymmetric 3 tires just didn't appear to be enough, so I started at 38psi and worked down from there. 38psi was too hard, although definitely improved the tire's performance. Anyway, to cut a long story short, I found out two things about these tires. 1) They take a very long time to settle and bed themselves in - somewhere between 200 and 500kms, believe it or not. 2) The best pressure with a good balance of ride comfort, low noise and dynamic performance was found to be 35 to 36psi, but this "goldilocks" pressure didn't make itself totally obvious until the tires had totally bedded in. Now though, after doing about 600kms on them I can confidently say that this really is a brilliant tire. Not quite as quiet as the Michelin Pilot Sport 4's on some surfaces, and yet quieter than the PS4's on other surfaces. I know, it's really strange, but I'll put up with occasional noise that they make and just enjoy how they have transferred my car for the better. They have definitely increased the fun factor of driving my car. Just take the time to bed them in before you objectively and subjectively judge them. You won't regret it...
