This is my wet conditions review, extremely heavy rain / sitting water, on country lanes and dual carriageway, and will return with a dry review at a later date :
Having used Bridgestone Potenza RE070 for many years, I recently discovered that Bridgestone had decided to discontinue them. However, I have now had fitted 4 x Bridgestone Potenza Sport, and they seem fantastic.
I have only wet tested them today, and not a hint of tramlining (something RE070 was renowned for) country lanes, negative cambers, deep standing water, no issues whatsoever from the new Potenza Sport breed which seems to get on harmoniously with the rugged yet symmetrical Subaru AWD system on my 2007 Impreza WRX STi. For the record I am running standard suspension and springs all round.
I feel the tire is extremely sturdy, brilliant traction, sticky compound, and with a decently stiff wall, yet not uncomfortable by any means, and a very deep (approx.10mm) rim protector built into the bead to protect my standard 17" Enkei rims. I did a lot of research into which tire would work for me, I do mixed driving in mixed conditions usually, and Potenza Sport is a cracking contender for the job.
These tires were an absolute bargain at £75 GBP each (not fitted) but delivered to my door, and looking at the DOT code, were only a month old when I received them - fresh!
Zero aquaplaning to report, but there again I was being half sensible around the rain soaked twisties of Surrey in the UK, but equally no aquaplaning on a dual carriageway which was virtually flooded.
The response and feedback was very good indeed, and the car was very compliant to my commands, and confidence inspiring from the offset.
Braking also seemed to be fine without issue. These 4 new tires got a good all round wet test today, and did extremely well.
I have no doubt whatsoever that these tires will be awesome in the dry. They seem quieter than RE070 - which I welcome.
Would I recommend? Yes, 100%, would I buy them again? yes 100%
I was very concerned as to what tires I could try to supersede the old faithful RE070's, and I know I have made the best possible choice. The research does pay off, as does trust in a brand you know and like.
RE070 was designed and created in 2004, but in those 17 years the tire construction technology, compounds, and tread patterns have moved on in leaps and bounds as I discovered today (15th May 2021)
Well played Bridgestone, you've created a very decent tire to match / beat your rivals, and priced it spot on. Thank you.
I am more than happy to submit my review as, on the scale of things, there isn't yet many reviews out there on the Potenza Sport - the new kid on the block who doesn't have many friends yet, but who means serious business that's for sure.
I cannot offer feedback on wear at this stage so have rated N/A for now and N/A for dry grip.....but I will return soon!
