Tires Squeal in tight turns?

[bpossel]

Sorry for all of the questions, but trying to get to know my new baby...

When I make sharp, slow turns, ie. in the parking garage, pulling into my garage, the tires squeal...

The car has Michelin MX4 195/75/R14 tires installed.  I currently have the front and rear air pressure set at 32psi.

Inside the trunk lid (original sticker in trunk), it states 26 front and 32 rear.

What is correct?  Should I follow the trunk reading?  This would mean lowering the current pressure in the front wheels.

I always thought that when tires squeal that it indicates that the pressure is too low?

Confused...  any advice is greatly appreciated!

Hi Bob,

The pressures quoted on your original boot sticker would be for the original size tyres of 185 HR 14 (80% profile)

Modern tyres with different treads and tyre wall/profile height and construction will require pressures stipulated by the tyre manufacturer.

I run 28 psi in the fronts, car feels a bit more stable on the freeway with that pressure.  I don't think the low speed squeal necessarily indicates low pressure, every car/tire combo I've ever had squealed in low speed turns, especially on concrete surfaces.

I wouldn't worry too much about front tire squeal in parking garages at all.  Just about all cars do this.  The concrete floor in indoor spaces is generally finished to a smoother finish than outdoor concrete and does not weather and erode over time as it does outdoors.  The front tires do not both describe a perfect arc when at full lock so one tire will "scrub" a little, plus the the front tires may "push" a little on the smooth surface when you are turning, thus the squeal. If you think that your tire squeal is loud, you ought to hear what a turning car sounds like on a painted garage surface!
