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.

“2025 Formentor VZ with 19s and Bridgestone Turanza T005... is 38 psi OK? Title says it. Car felt off lately, checked pressure and all were around 31 or 32. Sticker says 36 for W rated (which is ours) and 39 for Y rated. I went for 38 because there's usually 2 people in the car at all times, not 500kg but figured a drop of 1-2 PSI and I'm at 36. Wondering, 38 ok? What are you running? What a difference the 6 PSI makes though... wow.”
“The Bridgestone Turanza T005 UHP Summer tires suck My BMW i4 e40 has 8k miles on it. I usually never get flats, but in the past 8 months I have almost been stranded 3 times by flats, and I have had to replace two of tires because they were completely worn. These Bridgestone Turanza T005 UHP Summer tires are terrible. I've been replacing the worn tires with run-flats, but probably time to move to a different brand and all-season tire.”

Bridgestone Turanza T005
Dunlop SP Winter Sport 4D
Built for different seasons: Dunlop SP Winter Sport 4D is a winter tire, Bridgestone Turanza T005 a summer tire. Each score is measured against tires of its own season, so the two are not ranked against each other — pick by the season you drive in.

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.
