Best test result: #6 of 6 in 2010 Autocar Tyre Test - RWD (overall ranking)
“The RE050A is an old design. Tirerack tested it all the way back in 2004 That isn't to say it's bad, it compared well to other tires in its class. Bridgestone also makes some really good tires (Blizzaks and RE-71Rs come to mind, experience with both, they are great tires).”

“As someone who just bought a dedicated winter tire because my Pilot Sport AS4s don’t do well in just cold, let alone the snow, I’d go for the cross climates. In my experience, around 36° F the Pilot Sport AS4 start to get stiff and lose traction. Add cold with rain or snow/ice, they are outright squirrelly.”

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
The Bridgestone Potenza RE050A is recognized as an older high-performance summer tire design that still delivers strong dry grip, handling, and cornering capabilities. While some users appreciate their longevity with proper maintenance, others note reduced wet and cold weather traction and point out that newer alternatives are available.
“My invoice says I travelled 71500km (just under 45K miles) on the RE050A .. but I do a lot of highway. I dialled out the toe front/rear to be toe neutral instead of toe in and rotated every 15K. Switch them out when the tread is near the wear indicators.”
“Got my Camelot rims mounted with Bridgestone Potenza Re050a tires!”
“Re050a is more of a semi racing stickies. It's more in line with the potenza race. Any of the popular sport tires i.e pilot sport or potenza sport will do. For me. I'd go for Toyo Proxes sport 2.”

Community opinion on the Michelin Pilot Sport All Season 4 is largely positive, praising its dry and wet grip, sporty handling, and ride comfort compared to stock alternatives. However, some users note trade-offs in extreme winter conditions, potential range or efficiency impacts on EVs, and faster wear on staggered setups.
“Replaced my Bridgestone Driveguard+ runflats with Michelin PSAS4 because I could get them price matched out the door at Discount Tire cheaper than a set of DWS06+, my usual UHP tire. I might have just gotten a bad batch but mann, those tires were rough. I drove them for two weeks and had them rebalanced twice. The best they could road-force balance them to was 14-16lbs. They were noisy and rough at highway speeds. Tire shop swapped them out with the Continentals and my G30 feels like a german car again. All the tires easily road-force balanced under 10lbs. I was expecting a better ride considering Michelin’s reputation and reviews but they felt worse than my worn run-flats.”
“I’m about to purchase a set of Michelin Pilot Sport All Season 4 tires for my 10th gen coupe. It sounds like Costco is the place to get them. I don’t have a membership, but my parents do.”
“logged close too 100k miles on my model Y and been through 3 sets of tires, I'll give you the ups and downs for each. Original Continental ProContact RX - lasted around 23k miles with average 267 wh/mi Michellin pilot sport all season 4 - lasted around 20k miles average 260 wh/mi (had nail puncture so replaced early) It was wearing down to an estimated life of about 40k mile. Turanza EV: lasted till 47k mile but 280 wh/mi Currently on Continental ControlContact Sport SRS+ 400mi in averaging 257 wh/mi. But already seeing tire wear. Truth be told they all drive about the same, sound the same react similiarly.. the only thing I notice and care about is tire wear and energy usage.”

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.
