I've had the front end checked twice. The car pulls left & right or follows a rut in the street. Had a front end alignment also, still pulls. Tires have good tread, don't know what's going on?

 

This is called tramlining.

Tires issues can cause this.

Are the tires wider then original, performance type, use higher air pressure or have defects? Sometimes defects can be internal such as ply separation.

Are these the original factory rims, if not is there a significantly different offset then factory?

Too much negative camber can increase tracking. Camber is not adjustable without installed a kit.

Other issues can be worn suspension bushings, tie rod end, etc.

 

I had this on my car not too long ago. Tire place swapped around the tires and test drove it, car drives straight now.

 

Original rims. Tires are Cooper, stock size. They have been rotated. Maybe time for new tires? I also seem to have to check the pressure, (35) at least every other week, they loose pressure. Frontend has been inspected twice, told it's fine. Thanx for all the info, GTREATLY appreciated!

 

Tires should not lose air that quickly if at all. Do you lose pressure in the front tires? Does the pulling get worse when the pressure is low? I think your tires need to be sealed.

 

Lose pressure in all tires. Have to keep an eye on them or the light comes on. Pulls with high or low pressure.

 

I would first, get your tires inspected at your favorite tire shop and have the tires sealed, sounds like you have bead leak. While they are at it, actually have them swap the tires around and not rotate them. Tires that lose pressure within a week are not right. Are these tires new? They sound defective.
