    Re: Michelin PS2 VS Pirelli Corsa tyres (semi-slick)

    you cant compare those 2 tyres, I in Italy use the corsas for the porsche formula club championship and are semi slicks.
    BUT PAY ATTENTION: the corsas are made in 2 different types.
    - the corsa system... more street
    - the corsa ....especially for track

    The pilot sport 2 is normal streeet tires what I know.
    You should only compare cup vs corsas

    But if you mean corsa system VS ps2 PIRELLI MUCH MORE track oriented.

    I'd still take the PS2s. On the track I prefer cups, or just go for Hoosier rain's

    Wet perforamnce is the only reason to select the Pirelli Corsa over PSCup - which is a great track tyre

    Re: Michelin PS2 VS Pirelli Corsa tyres (semi-slick)

    resume:

    dry: sportcup best
    wet: corsa best ( with sportcup you have difficulties to stay on the track)

    ps2 is never a good chosie when comparing with corsa for track use and prestanda.

    Re: Michelin PS2 VS Pirelli Corsa tyres (semi-slick)

    I don't have direct experience with the Corsa's but you'll find that the factory recommended tire pressures are way overinflated for the track. Especially on a hot day.
    Experiment with lower pressures (gradually) and see what works best. Talk to more experienced drivers at the track and see what they're doing.

    Re: Michelin PS2 VS Pirelli Corsa tyres (semi-slick)

    depends on temperature, very hot =lower bar

    in bar at cold tyres
    front 1.8/ 1.9 rear 1.6/1.8
    after some laps check that it's not over 2.0/2.2

    there you have the best performances

    the Corsas work at 2.2 hot .
    you must put 1,7 front /1,6 rear with cold tires .
