Why does my car pull right when I upshift?
My car is a 2004 with 12,8xx miles. I recently pulled it out of storage and put on a brand new set of Goodyear F1 DS-G3's on 17 inch BBS RGRs. The car has never been wrecked.
Ever since I put the new tires on, the car pulls to the right when I step on the clutch and upshift. In fact any time I lift off a moderate or greater throttle, the car pulls right. Imagine rolling along at 80, lifting off the throttle and having the car pull into the next lane--it sucks a bit.
The wheels and tires are new, 17x7.5 215/45 front and 17x8.5 245/40 rears. I assumed this was an alignment problem, but the car is within specs all around--just checked this weekend. The tires are 34 PSI all around.
Under acceleration or coasting/braking the car tracks perfectly straight. I am going to try to find someone to swap wheels and tires with me to confirm it is (or is not) the new wheels and tires.
Any other ideas would be helpful.
Thanks.

Ah, I've found your problem. You're in Ohio. Leave Ohio and your problem will be solved...
Sorry, just couldn't resist.
Are you sure you're not somehow pulling the steering wheel slightly to the right as you pull your right hand off to shift? I've done that before.

No one has to agree with me on this, but I definately feel the same thing specifically taking left hand turns under load.
Honestly the motor is torqueing to the left then when you let off it shift back to the right then you shift and get in it again, and it comes back to the left.
sit there and rev that thing up one time, or do a little series of revs, you'll feel the car shake side to side a little but, the motor is moving.

^ i've checked the pressure on my tires plenty of times and inflated them to the same amount of PSI, it still pulls to the right when i push on the throttle. kind of annoying yes, but i can live with it. BTW my car DOES have that odd passanger side is 1/2 inch higher than the driver side thing going on. still has gone unexplained-though there are plenty of threads about it.

I let a few others drive the car on Sunday and they noticed the same issue. I don't think we all are jerking on the wheel, I know I am not. Besides, the car pulls right when rolling in a straight line at 75-80 and simply lifting off the gas. With both hands on the wheel, there is no driver input into the steering.
More pressure? 34 psi is not ideal? Both rear tires are exactly the same pressure cold.
WarrenW, that is a good one, alas politics won't solve this (or any other it would seem) problem.
LSD problem is something I had not considered. The diff uses spider gears, so there are no clutches to wear out. The diff fluid was flushed and replaced with 607 about a year ago.

We checked his pressure and myself and two others came to the same conclusion.The driving dynamics of Scott's car does not invite a secure feeling of control when upshifting or during throttle modulation.
Very strange.
