205/45 R17 Tires

The tires grip well but they will 'skip' on some corners with a bumpy surface which is scary! Ive been using this tire model for over 40K miles but have decided runflats are just to harsh on the car itself and they wear so quickly on my 2012 Mini Cooper JCW with it's camber!

Before switching to the Bridgestone Potenza Sport Evo (in size 205/45/17), I had the Yokohama Advan Neova RS (in size 205/55/17). The difference is night and day—in favor of the Bridgestones. Their grip and user-friendliness are on an entirely different level; they are in a different league compared to the unacceptable Yokohama Advan Neova RS, whose only real advantage was minimal wear.

The Bridgestones seem much more prone to wear, but that’s a fair trade-off given their excellent performance—after all, you can’t have everything. I can’t comment on their performance in the rain, as I haven’t had the chance to drive in such conditions yet.

To wrap up, they are quiet and feature a very solid sidewall—though perhaps not quite as good as those found on older Bridgestone models.

I recommend them without hesitation!

Daily/spirited/track driving.
Good dry/wet grip, however they end up overheating, losing some grip and getting damaged. The treads of the tire loses its integrity.

After reading the reviews on these tires, which are mostly negative, I must say I did not experienced any drama on any road surfaces in the dry or in the wet. The Firemax were fitted (new) when I purchased the car from Furrows, they are quiet both in town and on the motorway, I drive safely and respect speed signs and average 47 miles per gallon, for me, the worst aspect is wear, only 17000 miles driven and the front tires are worn out to the 1.6 legal limit while the rear tires still have some tread, I will not buy these budget tires again. I will put the Falken ZIEX ZE320 on the car since they have excellent reviews and are very well priced, I will review the Falken after I drove a few thousands miles.

These tires are decent for mild road driving but my god do they have soft and floppy sidewalls. I do quite a bit of spirited driving in these (and 1 track day a year) and the front tires chunked badly on the outer shoulders after about 7 months. As a point of comparison the stock tires on my Mini (before I changed them out) handled the same level of driving for much longer without chunking. Not buying them again.

On the track they get greasy after ~10 minutes. They are really good in the rain though.

Don't really understand why they made these performance tires so floppy. They work great if you're not doing much hard cornering - but if that's the case you don't need UHP summers to begin with.

A set of two to replace two severely unevenly worn tires on the front axle. They were the first generation Quatrac Pro with 85,000 km. The Pro 2 is a huge difference compared to (fresh) Pros of the old generation. They are much quieter, all the vibrations and weird cornering noises are gone. The design seems completely new, I have high expectations of it and will post an update in a few thousand km.

Being said I have driven these tires for only 350km I can only give my impression about the starting life of these tires, about 1000-1500km should be performing better, I have a Mini Cooper S R56, a very handling car, I have been using SemiSlick almost these 10 last years ( Federal RSR 595 and the new upgrade) the differences in this car bewteen both tires are not huge, The semis in 1200kg front traction car are very difficult to warm up in the rear-end, even trying to adjust the pressure, but the Kumho as they work in a fewer temp range you feel the rear very stable, the handling input seems quite similar than Federal in terms of precision, my driving style has always been very pointly with input so changing the Federal for these Kumho has made to me change my driving style, the huge amount of grip makes the car very neutral, I didn't find any understeering situation, but it's true the rear never will want to overtake you, it's always sticked tl the ground, that combined with seems there is a short gap between the max grip snd the lack of grip makes me a little bit unconfident finding the max grip over lateral load. But for the price that these tires cost it a must, you can go very fast without compromising safety, no snaps or understeers and you can go very comfortable going calm, the tires dont sound a all ( to me, maybe for others they sound a lot, but Im comparing with a semi that over 30-40km you were hearing the tire eating the ground)

For the price they run premium brands very close, but they wear faster, particularly on a FWD car with lots of torque.
