So Just got a set of conti DWS put on for winter. I noticed that when ever I'm on the gas the car pulls to the driver side, as soon as I let off It corrects itself and drives straight as an arrow. The car drive straight as can be when coasting but as soon as I give it gas it goes left, The higher the speed and harder I give it gas the worse it is. What could be causing this?

have the shop that installed them rebalance?

 

[SiliconTek]

Balance is going to cause vibration at a certain speed. I noticed the same thing when I got my first set of aftermarket tires and it was basically just the added traction. I had everything checked, alignment, balance, etc. No problems there, after a few miles all was well.

My car pulled to the Left , but it only around this one turn and i found that it was the road surface on that turn wierd that my scion hits that same curve at same speed and it doesnt pull. think the smart all wheel drive is just getting confused on that turn due to the road conditions.

What are your road conditions like if they are like va there is not many smooth patches of road.

but defently check the balancing as well..

It's most noticable on the highway at speeds over 45. But I feel it on any surface, even on side streets if I give it some gas right off the line it just pulls and as soon as I let off it's fine. Going to have the shop look at it tomorrow, they said it sounds like torque steer, going to check balancing, and rotate them and go from there. They also said it could be a bad tire...

^^torque steer...i dunno know. Could be wrong though. Tire pressure good?

 

[Kracka]

Set your tire pressure and get an alignment.

I called Tire Rack, which is where I got them, they said it could be a bad tire. They told me to one at a time swap the front tires to the back and see if that helps. If so then they will send me a new tire if I find the one pulling. They dont think its an alignment issue since it only pulls when I'm into the gas.

 

[Badhazard]

what i would do is... rotate the front two tires side to side. rotate the driver front tire to the passenger front and vice versa. if the tires cause the car to go left after you rotate it should go right.

 

[Kento240]

I would def check alignment settings. Perhaps your Thrust Angle settings are off and causing the car to pull one direction during acceleration.


Just a quick thought.

 

[FLK]

If it's not alignment or balance it's tire runout. Runout on a bad tire will produce pull through lateral forces.
You can check it by a Road force balance with Straight-track. It detects runout/bad tires vs. bad wheels and will attempt to offset your runout or minimize it. Of course you should also replace the tire if it's really bad.

Just do what tire rack says to do and save your money on expensive balancing and alignment checks. If you have a tire pull and you rotate from front to the rear, it most of the time will pull to the other side (right side) under acceleration.

I had a tire pull on my spare set of all seasons. After many miles it's gone.

I swapped the front's to the rear, still pulled hard to the left. Then swapped driver front to passenger side front, car then pulled hard to the right. Then I swapped front passenger, believing it to be the one pulling to the back and problem solved. Car now drives straight! My mechanic said it most likely means I have not one but two bad tires, now being both rear since the first front to back swap did nothing. So tire rack is sending two new ones. They said it's uncommon but it does happen, getting two bad tires
