What real owners are saying

From Reddit, forums and review threads. Not part of our score

Tire A

Bridgestone Potenza RE050A

Mixed

Community sentiment regarding the Bridgestone Potenza RE050A is largely mixed, with drivers acknowledging solid dry grip, responsive handling, and decent wet traction when warm. However, many owners criticize the tire's harsh ride quality, high road noise, fast treadwear, high replacement cost, and complete lack of traction in cold or snowy conditions. Run-flat variants are particularly disliked for their stiff ride and difficulty of repair.

“tbear, only have my subjective experience to go by.. Had the RE050A as the OEM tires on by 2008. I could get them to slip and slid at autocross (not on purpose) even with an un-tuned automatic. Have switched to the Michelin Pilot Sport AS all seasons (they have changed the model designations since the last time I purchased but these are not the Pilot Super SPorts) and am finding the ride quieter and very very grippy. Seems like all seasons would be a good choice for the Atlanta area? rakessler”

“just installed another set, $1180 mounted/balanced. 245/45ZR18 front. 275/40ZR18 rear. factory placard says 28 psi front and 33 psi rear. add 4 psi for sustained high speed. tire placard says 51 psi max. i have been experimenting with pressure and 28 front is a limo smooth ride but destroys the shoulders of the tire. anything less than 35 in the rear and im looking at 15k miles or less for a set. at 40psi front and rear i have seen 27 mpg. at factory specs 28/33 front/rear 24 mpg. has anyone found the "zen" pressure that gives the best of both worlds. im seeking an even # front and rear to make it easy for the wife, im in afghan for 9 months of the year and she has to keep them serviced.”

“It's been 4 years and 30,000km's and the PS4S tyres have worn up to the wear mark on the back tyres. Any recommendations for a replacement? It's summer all year here. We have hot summer and less hot summer. I went with the PS4S because I found the OEM RE050A's too stiff and the PS4S was definitely softer. I would consider going softer again if there was a good option. For PS4S again it will be 2 x $564 for 235/40R19 and 2 x $610 for 265/35R19 = $2348 AUD or, if I try the new PS5 it is 2 x $374 for 245/40R19 and 2 x 472 for 275/35R19 = $1692 AUD The PS5's are way cheaper and have a tread wear of 340 vs the 300. I have also heard good things about the Falken FK510”

How do we compare tires?

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.
