Before I replaced my tires, my car tracked straight and true without the hands on the wheel.

Yesterday, I had the tires replaced and on the way home, it pulled to the right pretty bad. I checked the tire pressure, it was 27 psi all the way around so I reinflated it to 35 psi and the pull is less severe but still there. I'm still uncomfortable with the fact that I have a small drift to the right when I let go of the wheel.

Does new tires causes this because I told my dad about this and he said it'* probably the new tires... :?:

It just drifts to the right now...but not bad.

try rotating the 2 front tires

Forgot to mention that they're directional. so I can't rotate the front two and I just had the tires installed yesterday...

I checked the calipers for heat, the left and the right feels the same.

maybe get your alignment checked? i know you said it was ok before the new tires, but heck its worth a try. because when you have low pressure in your tires it increases rolling resistance quite a bit, and whichever way the tire can push back and get relief is the way the wheel will go., the only way the car will let one push off to one side and not the other side equally is alignment. thats about my only thought on this.

Edit: also, check your drums for drag also! i had that problem on my electra of a dragging drum and it would horrifically pull.

then swap the front and back one. that will rule out the tire/rim

New or used tires? Balanced? Could be a bad belt. That happened to me with a front tire.

Brian, they're brand-new. I got them from Discount Tires. They balanced it befroe they put it on the car.

I had an alignment done about 10K miles ago so it should be still aligned.

Were the old tires worn evenly?

Somewhat, I never really slowed down in the corners so the fronts wore faster than the back but beside that, they all wore evenly.

I'm still thinking brake, I'm going to take the wheel off and inspect the brake and take out hte caliper and regrease the caliper slider bolts and bleed it so I can eliminate all possible brake suspects

Good idea or no?

I personally would take it back and tell them that since they did the tires you have a drift to the right and see what they will do for you.
