Why do Pirelli P zero summer tires skip or jump when first coming out of driveway cold?

[67go]

They are above the 45 degree requirement when I back out. When turning to go I have to go very slow or the front tire skips or jumps. Very annoying. Reading briefly, I see they call it the Ackermann effect. Very common. Thread already beaten to death? Appreciate any help.

Summer only tire compound gets softer when the exterior temps are warmer and after driving on them for a few miles; as the tire heats up, the compound gets more pliable or sticky…. The colder the exterior temps, the tire compound becomes much harder.

In cold weather, the surface of the driveway and or road is cold and the tire compound is also cold, but the rubber has become hard from sitting. Couple that with trying to turn the wheel when pulling out backwards or parking, and the tire will actually skip across the cold pavement.

This is why Summer Only tires (any brand) usually has a warning or cautionary note that they should not be relied upon or driven on when exterior temps are 40* and below…. Can you drive on them? Certainly. But be aware that traction and performance will be severely diminished and you cannot drive (safely) in the same manner as you would when temps are 70*+.

I have experienced this many times in Minnesota and it is alarming. I have never had it happen with any other car (even previous generation mustangs). It makes a huge clunking noise. I have asked the dealership and they, of course, said everything was fine.

I do not think it's anything to worry about, but it's very strange.

Simple, they’re Pirelli’s, and everyone knows Pirelli’s suck

Thought my car was broken, then I switched the pirellis for Michelins. No more issues.

Them or Conti’s here. I feel outside of the southwest where rain is rare and its usually hot and arid, Pirelli’s are acceptable, but not elsewhere

I use mine and the original boat anchor wheels for burnouts now. Lol.

In the Southeast here, where a cold winter morning is 45... I called 'em hockey pucks when I still had summer tires. They were stupid-hard when that cold, as Cobra Jet points out. I swapped for A/S once they wore out (which happened quickly).

Ill never forget fishtailing going down an exit ramp at 35 with my bonestock B7 A4 Quattro, not going nuts or anything, when they had pirelli’s, during light rain

that says all you need to know about them

Puh-lease... they don't suck.

Under 10c and you guys expect miracles.

My FireHawks do the same when cold. Yet grip like a motherfooker when warm. Same with a buddies Michelins.

Guess they suck too.
