It happened this morning again... it does it every time i really get on it

 

directional tires with staggered wheel sizes.

 

Different sizes front and rear.

 

Assuming all things are equal, there is more weight on the left of the car because that's the driver's side (in the U.S.). The weight of your body, could certainly create a left-leaning bias.

Try doing a hard pull with a passenger of your same weight next to you and see if it happens.

In any case, an alignment is a wonderful treat regardless. I always feel like my car drives sooooo much better after an alignment.

AH HAHAHAHAH way too funny man, I NEVER thought of that and this is DEFINITELY why there is pull to the left, im 300LBS!!! and I never drive with a passenger! god, you guys are so on top of your came its scary! Im glad I asked!

 

They only time this happened to me n the past it was because I had different air pressure in the rear tires. Also one was new and the other one was 70% tread life.

Check the life of the tires and the air pressure.

Cheers!

 

Not sure if you are being sarcastic, but if not, glad I could help. I am sure you could get an alignment setting that would correct for that if in fact you are 300 lbs and never have a passenger next to you, it might be a good idea. Might help the tires wear more evenly, too.

It's funny, I recall the guy who does my alignment mentioning to me that on BMW's, the suspension is set up to allow for a 200lb driver. I don't know if that's true or not, but I did notice that on several BMW's the driver's side was about 1/3 inch higher than the passenger side with no one in the car. With a driver on board, that 1/3 ich delta disappeared.

nah man, I was serious! Thanks Cattman!

 

Does it pull when you engine brake from near redline down?

 

Depends on how much its pulling, well since cars are rolling mass it's common for some cars to pull because of all of the power and friction. Thats what happens with my quad, so all I do is take some hard turns.

 

Could be p-factor that causes an airplane to yaw left. J/K

 

The solution then is to put a 300lbs passenger. I guarantee you that it will not pull to the left. In fact, it will not pull at all... (sorry, no offense, but I couldn't resist...)

 

or I could just skip lunch and take a big ****

 

This absolutely should not happen. Yes, you might get a very occasional slight push one way or the other due to road imperfections but certainly not constantly pulling to the left under acceleration.

Make no mistake, there is something VERY wrong with either the car or tires and this condition is at best dangerous and at worst potentially lethal. Get the car to a dealer ASAP for your own safety.

 

Yes. I have a C4S on summer tires and when it is cold in Chicago, my car will also pull to the left. I was thinking it was either due to the tires being too cold or to the terrible Chicago road network..
