PSS - did anyone not find them great?
I replaced all my tires with PSSs last week.
I've only done a few hundred miles so far, but am a bit concerned that I seem to have the TC light flashing way more than with the OEM fitment tyres that were nearly dead on the rear. Did anyone else experience this? Did they take a while to get keyed in?

It takes about 500 miles before they feel "good". At first they will feel VERY greasy and sloppy. I would not even try to do an WOT runs nor any panic braking. Give the tires some miles to wear off the release gel on the tire thread. Then they will feel much better.
Also... I run 2.3 bar and 2.8 bar tire pressures. That also makes the tires feel less "soft" plus I drive at high speeds often so I want better handling at those speeds. Dack

I thought the tyre release agent was a different proposition these days and wore off very quickly (in other words, what Pete said ), but appreciate your experience Dackelone. I'm at about 350 miles, mostly motorway so far, so very gentle. But on acceleration - flash flash flash!
Pressures I will check - have in fact just bought a brand new gauge for this purpose. mlhj - straight line acceleration

On my first set of PS3's I was told to take it easy... not 10km after hitting the Autobahn do I roll upon a Ferrari Testarossa! Well.. in short order we were driving around 140 mph... and I had to bail out bc the tires felt VERY weird. The next day I drove to the Essen MotorShow (some 450 kms away) and only on my way home from there did my tires start to feel "normal".
This year (summer) I replaced my rears and drove to Stelvio to meet up with the otehr 1addicts. Same thing. Not until about 500 kms did my tires start to feel stable and normal. So... just take it easy until you have some miles and heat cycles into the new tires.

As you wear out your old set, it will grip better in dry conditions. Do check the pressures, I run 36 fronts and 34 rear. You might also want to check your rear alignment. Currently running 1.5 degree toe in.
My TC flashes a lot less now with the PSS, and I was just thinking today how much better it grips. However, I did change to much lighter wheels at the same time so it might have an effect because the suspension works better. My only complaint on the PSS is that it is noisier than the PS2s.

I would be interested if people already tried to Yokohama Advan Neova AD08?
The Supersports are good but I would appreciate some more dry-grip on the track. |

AD08s don't have sufficient load ratings for OEM sizes unfortunately, and I don't wish to up-size. I think I'll be getting the brand new Dunlop Sportmaxx Race tyre for my ZCP wheels, which is meant to be better than the Michelin Cups tyres for track use and also for wet grip. PSS, however, is a great road tyre.

OP: I replaced the PS2s with stock size PSS and never had nothing but exact opposite of what you experience. I also keep the pressures 36/34 like sparoz for routine driving conditions (driver only and in city).
The users who noticed more noise with the SS, are you guys with stock sizes like me? Cause I feel same or less noise with the PSS. I have to admit that I used the stock tires onnly 550 kms though and one thing they were not much worse than the PSS in general was the noise level. |

Currently running 219Ms with PSS for road use, and my ZCP wheels with PS2s have a small amount of thread left for track use. Will be experimenting with the Dunlops soon. |

Pressures checked - rears were 36 and 37, fronts were 35.5 and 37 (trust in local tyre place slightly dented...). Reset to 34 on the rear, 36 on the front. Quick test drive - certainly feels better. Slightly less hard ride for a start, and grip improved - I'm confident now that after another few hundred we'll be rocking.
Thanks all!

I'm interested in this thread as my next mod will be a full set of PSS tyres, once my PS2's are worn out.
However, the pressures being mentioned (34psi rear and 36psi front), are these higher than the stock pressure ratings? I can't remember off the top of my head but as I am also running more power and torque I wonder if I should be increasing my pressures on the PS2's to the same? |

However, when using road tyres on the track, pressures should be increased to a certain point to compensate for the soft tyre wall of a road tyre - this helps reduce tyre roll when cornering. But you have to balance the effect of air pressure on the contact patch area with tyre wall support. This is where track tyres are beneficial due to their stiffer sidewall, therefore do not need as much tyre pressure as a road tyre, and you can concentrate on controlling pressures to maximise the contact patch area and temperature distribution across the thread.

Best way to adjust tyre pressure is looking at how they wear out - it should be even wear across the tyre. That would be the correct pressure for usual driving style.
