well im investigating a problem with my car pulling left, and i was reading that some tires the rubber isnt exactly ballanced and can cause a car to pull to one side. This was taken from another forum.
The other type is due to small differences in the tire rolling circumference. This variation can be thought of as small differences in the number of times the tires rolls (under load) per mile driven. You can't measure this with a tape measure, it's that subtle. A small difference in this rolling circumference (or revolutions per mile) is not enough to work the differential and allow different tire rolling velocities, so the front end acts like a solid axle.
This is like putting a smaller wheel on one side of an wagon axle - then trying to make that axle roll straight (it's going to want to roll in circles, right?). If you put driving torque on it, the largerwheel gets the majority of the torque. This acts through the suspension and steering geometry to cause a torque steer toward the smaller tire
Have the dealer swap the tires left-to-right, and see if the torque steer changes. If it does, then it's the second type of torque steer - the only way to fix it is through tire replacement. If not, it's likely to be related to something in the engine mounts
So i just wanted to try this to rule out my tires in my torque steer problem.
