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.

Hankook Ventus S1 noble2
Community sentiment toward the Hankook Ventus S1 noble2 is largely positive, with owners highlighting its competitive price-to-performance value compared to premium alternatives like Michelin. Drivers frequently commend its quiet ride, wet grip, and respectable tread life, though some note reduced handling sharpness compared to dedicated summer tires and increased road noise after higher mileage.

Fronts: $63.00 x 2 + shipping (214/45zr-17) = $152.16 Rears: $71.00 x 2 + shipping (245/40/zr-17) = $164.15 Originally, I was only going to replace the rears with OEM tires because my fronts were in such decent shape, but I was able to get all four wheels for cheaper than the two rears so I went that direction instead. As promised, I'd continue to report on these tires and with todays showers and mixture of oil/grime and left over sand from the sleet we recently had, the tires are doing as well as expected. Of course with the sand, it is easy to break the rear-end loose but it breaks when expected, no surprises.”
“Update 3: 20K Miles Front Tread: 8/32nd's remaining Rear Tread: 5-6/32nd's remaining The fronts have been wearing at an incredibly slow rate! :thumbsup: The rears wore quickly in the first 10K, but this seems to have slowed considerably in the next 10K. 20K Mile Verdict: Competes with or beats the best on the market today at a lower cost.”
“Quote: Originally Posted by MBNUT1 Better ride quality due to taller sidewalls? Physics? Rubbish.

But I do know that the ride on these Generals on my 20" stockers is very compliant and quiet, even more so than the 19" winter wheels I just took off the car a couple weeks ago. My old S600 came stock with ugly (IMO) chrome 18" wheels with Michelin Primacy summer tires. I swapped those out to 20" AMG knockoff wheels with Hankook Ventus S1/Noble2 all-season tires and there was no discernible difference in ride comfort. But the handling certainly improved. Those Hankooks were good tires too, but not quite as quiet as the Generals. These big heavy cars are too wallowy around turns as it is, especially with the standard Airmatic. The bigger wheels do sharpen it up a bit.”

How do we compare tires?
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.
