Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Potenza RE050A
Pros
- Phenomenal dry grip and cornering stability
- Precise steering response and sharp turn-in feedback
- Stiff sidewalls that enhance sporty handling and provide rim protection
Cons
- Harsh ride quality and stiff impact absorption, especially over rough roads and potholes
- Noticeable and escalating road noise as the tires wear
- Mediocre performance and reduced traction in cold temperatures or wintry conditions
Tire B Proxes T1 Sport
Pros
- Exceptional dry and wet grip for confident cornering and braking
- High level of ride comfort and shock absorption, outperforming stiff run-flats
- Lower price point compared to top-tier premium competitors while maintaining comparable performance
Cons
- Rapid tread wear and short lifespan, with many users reporting the need for replacements well under 15,000 miles
- Softer sidewalls can lead to a less direct or squirmy feel during aggressive cornering
- Occasional sensitivity to road grooves, uneven surfaces, and standing water (hydroplaning tendencies)

Tire A
Mixed
Bridgestone Potenza RE050A
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.

“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”

“I've had these tires on my E60 for the last four years - in the summer. I left them on the first winter I had the car and (re-)learned quickly that these summer tires are simply not designed for temperatures below 40F. Even when trying to drive carefully, I once slid right off the road while going around a corner. There were no other cars around at the time and no harm was done, but it was the last reminder for me. I now use a dedicated set of winter tires/wheels, and only put the summer tires on between April and October.”

“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”

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.
