Hi,

I put on my Michelin PSS tires a few days ago with the temperature still on the cool side and I noticed that when making slow, sharp turns, like pulling out of a parking spot, and especially in the rain, the front tires feel like they are 'skipping' along the road. The dealer told me that as soon as temperatures outside warm up, this will stop as these tires are made with a very hard rubber compound.

Anyone else experience this?

Thanks

It is normal due to Porsches suspension geometry. It does annoy anyways.

What pressure are you running? I went up from 32psi to 36psi and it reduced the effect to almost nothing. Worth a try to experiment with pressures.

CobbleStone

Thanks for the responses.

1. nvarga, do you mean that you experience this 'skipping' even when warm?

2. sp3000, do you mean that by increasing the pressure to 36 psi, the 'skipping' was reduced, even in colder temperatures?

Thanks

You can't avoid this in winter. even at higher PSI. It is the nature of performance tires. If you don't want this use all seasons.

CobbleStone

Thanks.

Is there a minimum outside temperature (on dry pavement) for which these tires can be driven at?

It is about 0 C now and rising during the day to about 4C during the day.

Thanks

I run winters and wouldn't put the PSS on until the temperatures are > 7C (45F) consistently.

Aren't the Michelin PSS tires summer rated and not all season?

As well, in my owners manual, it states that for the GTS model, the cold air pressures for partial load (comfort) should be 36psi rear and 39psi front,

Does this make sense?

Thanks

Yes. Summer tires.

Those pressures seem backwards. Usually the front wheels are lower pressure than the rears. Check the TPMS screen on the car's PCM for recommended pressures. Will depend on tire diameter, loading and type of tire (A/S, Summer, Winter, etc.).

Hi.

I went to the TPMS screen and I adjusted the pressures according to the information on the screen.

For partial load, the system said to adjust the pressures to:

F: 39 psi
R: 36psi

I know it seems strange, as fronts are usually less than the rears, but it even says this pressure variance in the owners manual. The ride is so much better now that I have added 3 psi to each of the tires.

‘14S, I couldn’t stand the cold and performance tire effects. Changed to all Michelin all seasons. Extremely happy, for street driving they handle well for spirited driving, ride better, much quieter, and last longer. I’ve run it to 120 and put cruise at 100 for long periods. I’ll never go back.

I'm late to this party, but the others responses are correct, summer performance tires don't do well in cold temps. Definitely do not drive aggressively on them in cold weather.
