Dear all-
My car is pulling to the left. It does not do it all the time but very frequently, especially during interstate driving (any speed).

What can cause this? Tires are actually not showing an abnormal wear and alignment did not correct the problem.

Thanks,
Mario

 

It could be the tires.
Some (directional) tires pull slighly to the right or left.
You can test this by switching the front wheels and seeing if pulls to the right.

My car used to pull to the right, and after 3 alignments, I changed to Pirelli non directional tires and the problem went away.

 

Its been cold enough here for me to pay PepBoys to rotate my tires a couple of week ago without helping the situation. but wil follow your suggestion since they probably did a diagonal rotation.
Thanx

 

It can very well be your tires. I remember when I had my car, I had directional tires. I took the car into Sam's for a rotation and balance, they reversed the direction of the tires. Well, long story short, I switched them back around and everything was fine again.

Another thing to consider is the crowning of the roads. A lot of highways have a crown so the water can have some place to go when raining instead of puddling on the ground.
