From Reddit, forums and review threads. Not part of our score
Community opinions on the Bridgestone Turanza T005 are divided. While some drivers praise its wet-weather performance, highway stability, and value compared to competitors like Michelin, others report issues with excessive road noise, stiff comfort levels, rapid wear, and poor grip in certain conditions.
“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 tyres... Are they really shit or is there something wrong with my car? I've just had brand new ones fitted, I don't expect them to be amazing in this weather but I'm slipping and sliding all over the place. My car has less grip than my old tyres with 2mm left. Seriously, I went round a roundabout last night at 20mph and drifted out from the inner lane. Could there be something I need to get checked because I don't feel quite safe with them on... 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.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
