Tire Squeal in the Morning
Just curious if anyone else's tires squeal in the morning. I'm almost certain that its my front drivers side tire that squeals when I first pull out of the garage and turn in the morning. I have a 15 AWD F-Sport and I'm running continental ProContact LS tires(1000kms so far) and have checked the tire pressure and alignment was done when tires were first put on with no issues. I think its normal because my other car does the same thing with Pirelli P6 tires but only first thing in the morning.
Any ideas if this isn't normal?

Read about Ackermann Steering Geometry and also about Scrub Radius and Squirm.
When a car with a tight suspension and wide tires makes a small radius turn at a slow speed, one of the front tires can slip, jump or jerk...or squeal.
You'll find it slips/skips easier when you drive over a surface that has both dry and wet patches - with the wet surface making it slip more, or when turning sharply on a surface where there are painted lines (e.g. parking lot) because the paint eliminates the friction of the rough surface texture. When the surface is very smooth the front tire further away from the 'center of turning circle' (see image) may have a tendency to squeal.
