The tires were bought naturally after a TireReviews review comparing the UUHP tires and the Goodyear Eagle F1 SuperSport having the best dry grip performance at the time. The PS4 was too lacking and the PS4s weren't available in the 18 inch size, the 19 inch size was a little too harsh for our roads, which is why the SSs were the best available tire at the time.
The GY SSs are simply superb at dry grip, on longer corners they hold the grip all the way to the speeds and lateral forces I was comfortable with, on shorter corners they greatly mitigated the understeery corner entry of my heavy car, after the apex they transformed the amount of power that can be put out of the corner while still having steering angle to the state where 2nd gear corner exits didn't have enough power to slide the car at 240hp full throttle, which was a first after Potenza S001s, Nexens N8000s, Sava UHP+s and even the Conti SportContact 7s couldn't grip that much.
The wet grip was slightly above average, enough to be safe on the roads, but nowhere near fun. The wear was surprisingly good, 8000miles for a set of 4 with rotations, given the shitty and curvy roads the SSs were dailyed on, it was quite a lot.
Comfort wise they were loud, bumps were very audible, highway tire noise was high, but all of that was countered by the amount of grip that was unbelievable for such a heavy car.
At the end of life, after 8000 hard miles, there was no tread left on 3-4cm of both inside and outside of each tire, they were completely smooth. The center maybe had 2mm of tread depth left. But the grip at the end of life was even better than during the actually usable tread life, reaching absurd high speed corner grip levels compared to all the previous tires I've used, including the SportContact7s.
Definitely the best dry grip tire I've ever had, without a shadow of a doubt.

I have these fitted to my BMW M140i the car is mapped so puts out a little more HP and TQ than stock.

Dry grip: Really good, grips well off the line and out of corners and you know where the limit is.

Wet grip: Is just okay, it's struggles with traction sometimes spinning in 5th gear (Auto) and at times you can feel the ABS kicking in under braking, it also struggles with clearing standing water a bit too. So overall not confidence inspiring in the wet. Anyone saying otherwise simply doesn't drive hard enough to tell the difference between tires.

Feedback: This tire really excels here through the steering wheel and the seat, I can tell what each corner is doing.

Comfort: Is compromised due to a stiff sidewall, but I knew that and I prefer feedback over comfort.

Wear: Too early to tell only covered 2k so far.

Conclusion: If you want a great summer tire that gives you sporty dry handling buy these. Just know that it does come at the expense of wet performance.

i've tried these tires in different cars, one is a c63 MB and the on an audi s3 , the main difference the size of the tires, on the 225, these tires are comfy and very low noised, on the other even nd on the 275 noise is louder , comfort about the same. thats it thats my only criticism. handling, cant be better baking damn .. face gesture making.. and all these with very good comfort levels. traction and steering response amazing. im really glad i purchased these instead of the asymmetric ...performance level is up without real compromise. amazing tires

Amazing handling qualities with exceptional steering reactions and highly confidence inspiring in dry conditions. Very good dry grip with good wet grip for a UUHP tire. Nevertheless not a wet performance tire as reactions in the wet at the limit can be a little bit demanding for average driving skill (if the electronics are turned off completely). Good wear especially when driven hard and/or frequently at the limit or on the track (about 5000 miles and still look quite new / about 6 mm left with even wear in spite of driving excessively fast curves). Had before the Yokohama AD08R which I loved. Compared with these, grip is on a identical level but Goodyear demands less heat in the tire to result in same grip. Turn in of Goodyear is a little bit faster and more precise and both are a bit "meaty" and side walls are strong. Therefore only average tire pressure (2.4 bar) is required and tire remains reliable also under extreme driving conditions (no imprecise behaviour or reactions of the tire). Comfort is quite good for UUHP (at least as good as original MIchelin PSS tires).

Bought these for my bmw 420d and can honestly say they are a great improvement over the potenza s001 fittrd before. Much more fun and the grip is insane. Have had michelin ps4 previously and these are much better. Thanks tire reviews for the recomendation

225/45/18 and 255/40/18

I bought these in 2020 after seeing the excellent reviews on this site. I have so far covered around 10k with them on everything from rough city streets to autobahns and tracks. They have been superb and offer an almost no compromise performance upgrade over more road oriented tires.

Dry
In the dry these really hang on. Turn in is direct and the grip is well balanced front to rear. I’ve also found myself able to get on the throttle much sooner and with more confidence than before. Braking is excellent and has only made my brake pads seem even more lacking than ever.

Wet
I was a little concerned that there would be a wet weather trade off with this type of tire, but if there is, I can’t tell. Traction is better than ever and grip is surprisingly good. I don’t use the car much in the wet and don’t tend to push it when I do, but incredibly they appear to perform noticeably better than the old Asymmetric 2s they replaced.

Track
The biggest difference compared to my previous tires is their ability to be pushed for much longer on track without overheating. The F1 SS is a huge step up in this regard and whilst I’m sure a dedicated track tire would be better again, you’d be making other compromises to get that advantage.

Wear, noise and comfort.
I doubt many will care that much if they’re looking at this kind of tire but it’s good to know you won’t need ear plugs, a seat cushion and an overdraft when you’re just driving normally. For wear, it’s possibly too early to tell but there’s huge amounts of tread left and no worn shoulders. I also didn’t notice any increase in noise but as the Z4 is relatively noisy, it’s hard to be sure. In terms of comfort they are a little stiffer and harsher over sharp ridges and potholes but it’s a relatively small difference and a price worth paying if you want that extra connection and directness. An added bonus is that my MPG hasn’t suffered either. I’ve been to Italy and back twice on these and there’s no perceptible difference in economy compared to other times I’ve done the trip.

Summary/TLDR

If you want a high performance road tire with more grip and feedback compared to a UHP summer tire, look no further. The F1SS moves the performance on from the Asymmetric range without giving up any amount of real world usability. It’s ability to handle heat is leagues above a normal summer tire and should satisfy all but the most dedicated of track goers. The only noticeable compromise for me was a slight loss of comfort over harsh bumps but given the nature of the tire and all the other benefits it offers it’s a total non issue.

I’m reluctant to give these a 10/10 simply because I’m no tire tester, but I’d say they’re pretty much perfect for anyone wanting more focus and grip without sacrificing the ability to daily drive the car in mixed environments and conditions.

Excellent premium tire for a dry weekend car. Mounted these to a 2004 Mitsubishi Evo 8mr and now this thing is the king of corners. Whatever corner I throw at it, it just grips, no tire squeal, no understeer or oversteer. would recommend to anybody after a dry grip weekend tire. Tire also has decent rim protection if you are after that. Decent looking sidewall. Made in Germany. Don't pay extra for the Michelin PS4S when you can have these for slightly less money.

I drive my car mainly on track, I done 4 trackdays in 4 months/5,000km. By the 4th trackday the tires were too worn take the power of my car and give me confidence into the bends. I done 5 trackdays last year on Michelin PS4s and they were only half worn. I do think the Goodyears are as good as the Michelins but did not last as long. I’m undecided what to buy yet for the next year of trackdays but currently swaying towards the Goodyears again due to price difference.

Changed to these from ps4s the ps4s lasted 2 1/2 to 3 years. Replaced the rears first and 4 months later ordered fronts, when I had them fitted tire shop said you will need to replace the rears soon I said I only just put them on. It's now 12 months on and the rears are shot to bits. Car is only driving as a daily driver. Worst wearing tire ever goodyear should be embarrassed to sell these.

I have been trying a number of new tires lately, PS4S, PS5 and F1A6 for having better handling and response for my 540i xdrive but at the same time getting city road comfort for my wife. None gets my satisfaction when doing spirited country road drive. I first hesitated to try F1SS after having read all the reviews on its harsh ride. To me it's more like a last resort. What a surprise to get the feel and response from the tires. It has much more solid feel and stability than PS4S when cornering and adequate ride comfort in the city. The noise is also negligible. However, I am not sure about the wet grip yet.

Great tire in the dry with good feedback. Good in a lot of wet conditions too, but some wet surfaces cause it to be very sketchy compared to PS4S's which seems to be more consistent on varying wet road surfaces. Wear was really bad. Less than 2000 miles and the fronts were dead compared to 8000 on PS4's on road use.

When it came to replacing the tires on my CSL wheels, everyone recommended I change to PS4S (recently bought the car and had some very old, dried out Achilles tires on them). And I was tempted to. But I remember watching one of Jonathan’s videos and remember him saying how good the F1SS was. I tried to watch every video I could find on the F1SS and eventually I ordered a set. These tires have blown my mind. I mainly do weekend runs on mountain passes/touge style roads and the occasional trackday. Because of our hot African climate, I wasn’t too worried about the cold/wet performance as it doesn’t really get below 8’C here in winter, and even then I don’t do much driving in anything but my daily driver. The F1SS are very quick to warm up and when they do, they really stick. Initial turn-in feels great, and steering feedback through corners is amazing. The rears seem to never run out of grip and even after pushing them on a fast, technical mountain pass, they just keep up. Road noise seems fairly non-existent. They have a normal amount of noise on the freeway, but overall I find it a quiet tire. I also don’t find them too stiff, they seem pretty comfortable considering the car is lowered. I have done one session of “spirited” driving in the wet, but didn’t push very hard. I didn’t feel like I was running out of grip at any stage though, I remember being impressed and thinking they shouldn’t feel this good in the wet. So far, very good! I’ve done about 6 or 7 demanding drives since fitting them and really love the way they feel and grip, especially compared to the MPS4S I’ve felt on other cars. If they last well with my driving style, I won’t hesitate to put these on other cars as well. It also makes me very excited for the next generation of these tires.
