Best test result: #1 of 16 in 2026 ADAC All Season Tyre Test - 185/65 R15 (curved aquaplaning)
“Hankook's 3-peak all-season tire, also called all-weather, is finally available from TR, though it had been out awhile now, when it replaced the 4S (4s1?) that was sold in Canada, but not the US. Like all the other 3-peak all-seasons that they carry, TR classifies the 4S2 as grand touring all-season”

Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

Community members frequently view the Hankook Kinergy 4S 2 as a solid, budget-friendly alternative to premium all-weather tires like the Michelin CrossClimate 2, highlighting its strong wet traction and good snow performance for the price. However, users report mixed experiences regarding tread longevity, with some noting rapid or uneven wear, as well as drawbacks such as highway humming noise, a stiff ride, and twitchy handling on ice.
“Hankook's 3-peak all-season tire, also called all-weather, is finally available from TR, though it had been out awhile now, when it replaced the 4S (4s1?) that was sold in Canada, but not the US. Like all the other 3-peak all-seasons that they carry, TR classifies the 4S2 as grand touring all-season”
“Softer alternative to HANKOOK KINERGY 4S2? Searching for alternarive to HANKOOK KINERGY 4S2 Good day to you! I recently decided to move to all-season tires. After checking reviews, costs and availability I went for HANKOOK 4S2. But i find them VERY stiff and not comfortable at all. (245 40 18). Would you please recommend an alternative with a softer ride? I am in Europe. Cheers and thank you!”
“Hankook Worn out after 15k miles Took my car in for a standard tire rotation and was informed all 4 tires only had 4/32 of tread remaining left. I was shocked. I've only put about 15k miles on in the 2.5 years I've had the tires. I don't drive aggressively at all. Mix of city and highway. Anyways, I got about a 75% credit on the Hankook Kinergy 4s2 all weather tires and only paid about $70 out of pocket towards my new tires (plus $90 balancing and mounting fee)! I went with the Falken Aklimate that were about $150 a tire. Just wanted to share my story. Can the softer rubber in all weather tires cause them to wear out faster in the summer? Only other thing I can think of is my car was parked outside for 2 summers in a south facing parking lot so maybe the sun just baked them and cause the tread to wear faster? But I would think that would be more dry rot related than tread wear. Read more”

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
