Falken 452
Car - Focus ST
Tyre size - 245/40/18
Previous tyre - Goodyear F1 Asymmetric
Dry Grip - very good, cant tell any difference than the f1
Dry braking - good no wobbling
Wet Grip - fine while driving normally starts to give when you push it in cornors
Wet braking - very good for the price, but think the F1s are better in this area
Sidewall - Very solid much stiffer than the F1s, had no pinches with these on potholes, had to replace F1s on two occasions due to pinches
Turn in - ok nothing to write home about
Feedback - great loads of feedback can really feel the road
Comfort - much louder than the f1s at motorway speeds can really hear the changing road surfaces
Summary - For the money its hands down they are best tyre out there for budget. I rate them better than the F1s as they last longer and are less likely to be pinched on potholes. I would definitely buy again
Let me counter that with my thoughts with the same tyre, on the same car except in the correct size (225/40/18).
Falken FK452
Car - Focus ST
Tyre size - 225/40/18
Previous tyre - Avon ZZ5 / P-Zero Nero
Dry Grip - Very good until they get down to around 4mm, where they take a pretty hard fall in performance IMO. That said, whilst they grip they offer little feedback.
Dry braking - On par with the dry grip review.
Wet Grip - I really liked their behaviour in the wet, there was decent grip available and when they reached their limit they let go very progressively. But, again the wet performance suffered as they wore.
Wet braking - It worked (I'm not sure how we can really judge braking unless a tyre is significantly better than another at it).
Sidewall - The sidewall is too soft IMO, I scrubbed the hell out of a lot of the sidewall at an autotest, and I had to run the tyres about 2-3PSI higher than the manufacturer spec. FWIW, I've bucked a wheel with one of these tyres on - not sure how they resist pothole "pinches"

. I believe its also responsible for the next 2;
Turn in - It does it but lacks feel here, needed the pressure increase to be considered acceptable.
Feedback - Don't agree here, I thought the feedback lacked hugely.
Comfort - They were quieter than my old tyres, and in this size there is so little comfort provided by the tyre that its impossible to call. Going back to the P-Zero/ZZ5 when I sold the car, they felt a bit harder though, I suppose.
Summary - I wouldn't buy for a performance car again, but was happy enough with their grip levels to put them on our family car, perhaps. The fronts also wore really quick - I'm talking down to 4-4.5mm in the space of about 3000 miles.
