Put some new rear tires on my car the other day and I noticed that at highway speeds when I accelerate my car seems to pull to slightly to the left and when I deaccelerate it goes back in line. It doesn't happen on every road but on I95 it occurs most. Is this a natural phenomenon do to the torque generated by the drive wheel (no LSD)? Could it be the new rear tires (Potenza 050A's) fyi the fronts are the same but are N0's and the new rears are N-1's. One of the technical guys at the tire rack said there are two different compunds between the N0 and N1 tires and said they should have only recommended N0's to match the fronts as the N1's will cause problems if mixed with N0's.

Appreciate any feedback.

Thanks

 

If it doesn't do it on all roads I doubt that it it the tires. I would think it would be due to the crown of the road. You may also need an alignment which should be done every few years (or less if you drive it hard).
