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

Swapped from Michelins.
In the front this turned the steering feel from responsive and sharp, to slightly dull and heavy. So much that i ditched the fronts and went back to Michelins super Sports up front.
Kept the Bridgestones in the rear, as the grip is phenomenal.
There are a few more things i don't like about them tho. Even if the sideways grip is great, they do tend to spin a bit easy. Even with lsd on a 300hp car, they do slip in first and second gear on the dry, in a mid engine car.
Also they are a bit noisy, and the life span is horrible. From new, to legal limit they have lasted about 15000km. Driving mostly on b roads.

TL;DR Great tire with a huge amount of dry/grip and excellent road feedback. Wear rate and noise is very high. Ride is firm.

This is my second review on TireReviews.com. My past tires on my 2017 (2018 for the Americans) Mazda 6 were a slightly-upsized 235/45/19 Yokohama V701. I've always been a fan of unidirectional and symmetrical tires, so the Bridgestone Potenza Sport tires were a departure from my previous bias.

For context, the Potenza Sport in my car's stock size was some 30% cheaper than the usual Michelin/Continental competitors, and just 5% more expensive than my prior set of Yokohamas. These prices are for Singapore, and for the record, temperatures range from 30-40 degrees Celsius all year round, and we get rain pretty often (50% chance throughout the year).

These tires GRIP. Whether its wet or dry, the confidence inspired by the Potenza Sports were always high. The stiff sidewalls translated to excellent feedback through the steering and I never once felt like the car would come loose. When it was dry and traffic was clear, the tire never failed to plant a smile on my face and it felt like I could never reach the tire's limits on public roads. In the wet, traffic tends to slow to a crawl in Singapore, but of the few times I had fun when it was raining here, the tire would still track very confidently around bends.

Now the negative feedback. The tires were fairly noisy even when new. And whilst the stiff sidewalls translated to excellent steering feedback and response, the ride was noticeably harsher and firmer.

As others have noted on this website, the wear rate is VERY high. I drove this car for 25k km (16k miles) when my car was 5 years old to 7.5 years old. At 7 years-old and my tires were at the 20k km (12k miles) mark, my independent mechanic (who does not sell tires) noted that my inside treads might not pass our local vehicle inspections (similar to UK's MOT, and our's is conducted biennially from the car's 3rd year onwards). For the record, I did manage to pass the test, thankfully.

I always had my car's tires rotated regularly at 6 months regardless of distance, and the wear rate was quite a surprise. I've attached a photo of one of my front tires at its end-of-life (2.5 years or use and at 25k km) and you can see that the inside tread is already at the treadwear indicators.

To be fair, I am running aftermarket camber bolts to for -1.5 degrees camber in the front. But to go back to my usual bias, I'm not able to do a proper cross-rotate to even out the inside tread for asymmetrical tires, which is a bit of a shame. If your car is running stock/less aggressive camber, I daresay you could eke out perhaps another 6k miles (10k km) out of the tire.

Due to the high wear rate, I've gone back to my old tire (Yokohama V701). My local tire shop gave me a very good price for the new set, so I'm happy to head back. Plus the V701's more relaxed nature probably suits the Mazda 6 better. I do miss the much better feedback and grip of the Bridgestone Potenza Sport, but the high wear rate was definitely a concern, despite its reasonable pricing.

I bought a pair as a front replacement for my Nexen SU4 since they were ruined by the previous tire shop with their shabby wheel alignment. This shop (different one) has Michelin PS5 and Bridgestone to choose from and obviously I picked the latter. Sadly, I am very disappointed from the start. Twice the price of the Nexen SU4, after 800 miles or so they still don't give me any confidence in them. I can't feel anything compared to the SU4 (and I have gone through 3 sets on the same car so far) and sometimes I wondered if my tires were touching the ground, even in the wet. The low frequency road noise is louder too. The only good thing is the side wall bulges out more than the Nexen providing a bit more curb protection.

Incredible, transformed the handling and feel of my 2011 Mazda MX5 2.0 Sport Tech manual.

I have a set of four 19" tires for my BMW 4 Series. I have had these tires for 2 summer seasons and about 15,000km. At first these tires had very good grip on dry and wet roads. Now after two years, these tires are terrible. The car skids with every stronger acceleration and braking is very weak, and the rolling noise is loud. The tires look cracked all over, as if they are old, even though they are manufactured in 2022. I will never buy this brand again.

This is my first experience with a 300 tw summer tire, so my ratings might be a bit high. However, these tires are insanely grippy when they are warm in the wet or dry, and the steering response is almost telepathic. They have to be really warm to perform at their true potential, which means about 20 minutes of normal driving or just 5 minutes on the backroads. I have never even come close to the grip limit in corners, though I am in a mostly Honda Accord 2.0T (tuned so it has ~280 whp and 360 wtq, and a stiff rear sway bar). It actually makes it a little harder to stay completely straight on the road because these tires respond to even the smallest inputs, but I have come to love this characteristic; it makes a mostly normal family car feel like a sports car. After 5000 miles and at least 30 hard launches, several 130+ mph pulls, and some backroad driving, they are surprisingly still at 6/32 on the front and 7.5/32 on the back and I haven't rotated them yet either. If I hadn't accidentally done a 10 second burnout while trying to launch in 40F weather, I'm sure the fronts would still be at 6.5-7/32. I guess these tires would wear much faster on a heavier and more powerful car, but if you have a car with around 200-400 hp and don't do burnouts every day, these tires wear reasonably.

Compared to the OEM Pirelli PZ4 (HN specs), this tire, overall was... worse. Maybe due to its slightly different size (225 vs 215) but mostly due to its different philosophy and inability to perform well on "glossy", worn, hot Greek asphalt. As a result I experienced serious traction problems, whereas with the OEM tire they were non - existant.

That's a pitty because the tire has a very sporty and direct feeling and in terms of dry lateral grip, was on par with the OEM tire (once warmed)
Unexpectedly, wear was not an issue to this car .

I bought this set of tires for my hobby car, which does 6000-7000 km per year. Would not recommend the Potenza Sport for a daily driver, because of extremely high wear. Other than that, exceptionally fun tires, amazing grip on dry and wet, extremely precise steering, the most fun tires I ever tried. My car is a FWD 3.0 V6, so it usually tends to understeer, but not with the Potenza sport, which make the car feel like a RWD. Simply amazing. As I expected, the front tires were done really quickly.

Bought a set of these to replace a set of Goodride SA-37. Wow, these things are very sporting biased with grip levels in the dry/warm being absolutely stunning. In the wet they remain safe as houses and don't mind standing water either. All very good??? Not quite, as their performance quite dramatically drops of cliff when you get cold weather (im thinking anything a few degrees centigrade and below). Its not to the point of being dangerous (aka loosing traction), but there is noticeable difference in 'feel', as if the car is suddenly running on a set of super hard cheap rubber. I would never expect a tire to perform 'the same' in cold conditions but the change is quite disconcerting, especially when you are used to such a high amount of grip.....Adding half an inch of snow in to the mix resulted in a car that had zero braking at all which was quite shocking (I will now not even attempt to use the car if there is a hint of snow about..... Due to sporting nature, these are also fairly noisy and I also don't think they will last very long looking at the treadwear values...... I purchased these as I had such a good price on them (must have been a mis-price by retailer to be honest, at £70 odd quid a corner and then proceeded to knock £100 off a set of 4), but i would not buy again (at full price anyway), when Michelin Sport 5's or similar tires available at similar cost that may not be 'quite' so grippy in the warm, but less 'lifeless' in the cold an not 'lethal' in a snow flurry......

Grip is out of this world in the dry and wet and they're so sharp on the steering, however the wear is really bad. 1500 miles and a track day and both fronts were done. Don't use them on track.

Amazing performance tires. I had PS4 before and over my favourite mountains i was able to overheat. Potenza Sport on the same roads showed no dip in performance, they take longer to get heat up. In wet/cold and before they heat up they perform worse tho. Amazing tires for performance driving but you are giving up grip in worse conditions.

The tire as a whole is very nice and reliable, but care must be taken because the grip on dry when the tire is cold is less. However, once it reaches operating temperature the feeling is wonderful ! The feedback from the road and the feel in a corner is second to none. In the wet it also performs super. Just be careful on cold tarmac with cold tires - then there is a loss of grip. I've been driving the tires for about 8,000km, but it feels like the wear is a bit faster than I'd like.

I own a BMW X2 M35i. 225kw 450nm. It has power to burn, now it has the tires to match it. Dry grip it’s a fair bit ahead of the Pirelli Zero, it is way ahead in the wet grip! I use to race motorcycles, so I push the car to its limit a lot. The car has a limited slip differential on the front and the steering feedback is fantastic. Braking in dry and wet conditions is sensational. I can’t understand why some reviews bag the mileage out of these, I have done almost 20k and rotated them only last week as the fronts were scuffing up on the edges compared to the rears. 30k is achievable, easily. 40psi on the front and 38psi on the rear keeps things in balance. Comfort is average, but if you want comfort buy a S class Mercedes with touring tires. Would I buy these again, hell yes!

i'm at 8000 miles, and 2/3rds through the tread depth. Handling in aspects is excellent.
