I have had these on the rear of my XFR for a few months now, it has the optional "R-S" size of 295/30/20. They get a hard life on a heavy >500bhp RWD car with quite relaxed electronics, and these are by far the best tires I have used on the rear of an XFR - various models of which have been my daily driver for 6.5 years now (about 90k miles covered in that time). Traction is superb in wet and dry conditions, and resistance to aquaplaning has been good as well. It is slightly concerning they come with

I had driven a Michelin PS4 before and I had high expectations. In the rain, they aren’t as convincing at first until they warm up. Much higher wear than promised, I hope they last 2 seasons.

I have these tires on my car last six months. When they were brand new the grip was great, I also did two track days with them, although with just a couple of quick laps at both of them. Grip levels and handling are very good while driving on the track, but nowhere close to that on public roads now after six months and 10 000 km I have driven on them. Front wheels are spinning in second gear at full throttle on some occassions when the tarmac is not so sticky (which didn't happen on my old and worn PremiumContact 6 so much), it feels like it's already worn out while it isn't, and now in autumn it feels like driving on ice when rain falls down. They feel plastic. Tire reviews tested them on the track with two other brands, and while the Michelin PS4S and Goodyear Eagle F1 SS lost about 5 and 4 percent of its original thread, Potenza Sport lost 40% of it. I definitely won't buy them again. If I don't want a compromise (like now because only situation when I have grip is on the track), then I will consider buying semi slicks instead.

With just 2500Km and 2 track session (50 minutes total) I had to change the rear tires. Front tires are also wearing very fast. Probably a decent tire for road use but not good at all for sport / fast drive.

Running them on my F90 M5C I have much better steering feel and less under steer on track days. On mountain roads there isn’t much difference to the PS4S or PZ4 I had on before as you can really push the car on public roads, but on the track the grip and feel was amazing

I have used several tires on my cupra r michelin ps4 pzero pz4 and the potenza sport the potenza is much higher level of grip just need the break in to have all the potential of grip even if it wears out quickly max 5000km on the front axle but it must digest a lot of power I would take the potenza sport mmt even if it wears out faster than the other track type tires but once hot, great grip even at the limit

The best Tires of 2021. Before I had GOODYEAR Asy 5. I didn't like them at all. Neither dry nor wet. Switch to these Bridgestones and the difference is incredible. Much more grip in dry and wet. The best tires I have ever owned. They are impressive!!

Fun to drive tire. Less understeer compared to Michelin Pilot Supersport. But they wear really fast.

I run original E39 M5 wheels with oe size 245/40 R18 front and 275/35 R18 rear. Bridgestone Potenza Sport on both axles. I can't praise these tires enough. The grip is insane! I can floor it in 1st, and there is no wheelspin at all! Even on wet roads! With other tires, the car has been kind of a burnout machine, but the Potenza Sports tames it. They run pretty wide for a 275, so the outside of the rear tires touch the fender ever so slightly on full suspension compression. I haven't dared testing the cornering limit of the tires on public roads, but I have tried cornering on the limit of my own bravery, and the tires just grip. Wet roads is no problem either. The tires offer confident handling and gives good feedback. Very stable at all speeds, but on very worn (thanks to people with studded winter tires) asphalt there can be a hint of tramlining. Not as much as expected, considering the sharp shoulders of the tires, and doesn't feel scary. Comfort is ok. Not great, not bad. A lot of external noise, but the car is pretty quiet inside, except on old rough asphalt. Sadly they have already started ozone cracking slightly. That's disappointing for a tire in this price range. It's not because of washing chemicals or sun, as the ozone cracks is even apparent on the inside. The tires also get pretty brown, and the only thing I've found that makes them black again is Carpro Perl (water based tire shine, mixed 1:1 with water). The ozone cracks started appearing before I used any tire shine. Either way, I'm blown away with the performance of these tires. Wear is also very acceptable, with the rears down to 4,8mm on the inside, and 5,5mm on the outside (measured 6,3mm on the inner groove when they were new). The fronts are at around 5,5mm. Pretty good for a heavy and relatively powerful car on grippy sport tires over 3000 enthusiastic miles. I'm pretty sure I will buy another set of the same tires when they wear out.

Have had these on my FK2 Civic Type R for 7500km now, with 6500 of those km-s coming from a European road trip to the Nürburgring, on German autobahns and through rainy Italian mountain passes. The tire is great, it really is. I measured the tread depth at the beginning of the trip and came up with 7mm (essentially brand new). At the end of the trip, the front tires were at 5mm and rear tires at 6mm. At the Nürburgring, it took 6 (120km) hard driven dry laps to reduce the tread depth about 0.8-0.9mm (front tires). For those who read reviews saying that these tires don't last or that they wear fast on track, don't be discouraged. I have no idea how those people drive their cars, but less than 1mm of tread lost in 6 fast laps of the Nürburgring, on a car that EATS front tires is just amazing. Now on to the dry and wet performance. Everyday driving is great, the sound is not too bad (every single tire is going to be loud in an FK2 Type R) and handling is great when the tire is cold. On the track (the Nürburgring) the tire is AMAZING. For a road tire, once it gets warm, the grip is just monstrous. My friend ran Cup 2 tires, came on as a passenger, and was impressed by the amount of grip a road focused tire offers. The tire is predictable, feels great and sharp on tight turns and is very stable at high speeds. The sidewall is rather stiff, so the tire did not roll on itself too bad on high loads/low pressures (compared to for example Michelins, which have a very soft sidewall). The tire is also very good in the wet. for about 600km-s I got to try it out in rainy Italian mountain passes and I never lost confidence in the tire. I don't think I had a single ''oh crap'' moment, even when pushing. In conclusion, the Bridgestone Potenza Sport was about 50 euros per tire cheaper than the Michelin PS4S, and with the tire offering performance AT LEAST as good as the PS4S, I have no idea why I (or anyone else) should use any other tire for everyday (plus a little track) use.

I like pure performance. Intrigued by the reviews of other users I must confirm that the expectations have been met. I don't run on the track, but on the road these Bridgestones are unrivaled at the moment, they seem to be unbeatable. They are truly the new benchmark in sports tires.

Very disappointed when using high performance, no grip at dry when accelerating, they seek road grooves very much and because of that they are very scary to accelerating. They bounce when accelerating. I had before Hankook Evo2 k120 tires which didnt do these all shit things, they was much better tires for high performance. If i knew how bad these Bridgestone Potenza Sport tires are, i wouldnt buy them.
