Michelin PS2 Question
 

It's supposed to get COLD (well, cold for Houston anyway!) tomorrow and drop into the mid 30's...

At what temperature should I no longer trust my new PS2's, which are considered high performance summer tires? 32 degrees farenheit?

You will be fine,just don't go driving super hard on cold roads.

I have PS2's Randall and that is the rule I abide by. If it's near freezing the car doesn't go out. It probably won't hurt anything to drive it around 32 degrees but I wouldn't drive aggressively if you take it out.

I'm certainly planning to go lightly on the throttle tomorrow, but I just wanted to know what to expect. The Kumho's I had were as slippery as I don't know what when it was coolish-cold outside. If it was in the 40's and wet, forget about it... waaaay too dangerous.

Randall, I think the tire people or Porsche says <45 degrees. That's what I remember reading somewhere.

just another thought,
All tires will heat up as some you drive (depending on amount of time driven, driving style, etc.). "Actual mileage may vary" :)

Example: track day in SC in January. Morning temps in the mid 30's for the 8:00 runs - EVERYBODY is slipping & sliding. But, as the day wears on, temp rises, tires get hot, and by lunch everybody is letting air out to keep the pressures right.

So, moderate to long trip at marginal temps - the tires will probably heat up enough to be fine, though maybe not a good day to probe the limits.
Short trip on a cold night to the mini-mart for more eggnog: drive carefully!
