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.

From Reddit, forums and review threads. Not part of our score
The community generally regards the SportContact 7 as an excellent ultra-high-performance tire, praised for exceptional dry and wet grip, direct steering, quick warm-up, and good rim protection. Many rank it at or above the Michelin PS4S and ahead of the PS5 and Goodyear Asymmetric 6 for outright performance. The main criticisms are fast tread wear (often about 10–15k miles), low starting tread depth, softer sidewalls, some tramlining and noise, and poor durability on track.
“Had the same dilemma, went for PremiumContact 7 in the end for my Cupra ST300 4drive. Both have great traction when wet and dry, SC7 is more for an overall aggresive driving, while PC7 are bit more comfy, for a mix of sport and city daily cruising. Both are very quiet on the highway.”
“Not a C7 but Continental SportContact 7, similar or better than PilotSport 4S in most aspect but a bit noisier, wears faster too”
“I have Continental Sport Contact 7's on my S550 and the are better than the PS4S in my view (plus they stack up well in independent reviews as well)”

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.
