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 sentiment toward the Cooper Zeon RS3-G1 is generally very positive, with owners highlighting strong wet and dry traction, quiet operation, and exceptional value for money compared to premium rivals. It is frequently considered as a budget-friendly alternative to the Continental ExtremeContact DWS06 for high-performance and daily driving needs. Minor caveats noted by drivers include potential initial flatspotting, firmer ride compliance, and differences in steering feel.
“Going with a second set of wheels is really the way to do it. I run Cooper Zeon RS3-G1 all-seasons (305/35R20) during the spring, summer, and fall months, and go with Bridgestone Blizzak LM005 (285/40R20) on aftermarket wheels during the winter months here in Colorado.”

I got them last year and they have been great I do try to drive my car in the colder winter months, as long as there is no snow or salt dust on the roads. I never go to the track or drag strip, so these tires should be just fine.”

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.
