Sir, Is the car swaying left or right? Have you noted any peculiar wear-tear in your car's tires? Have you checked if the car is moving in straight line if you leave the steering wheel(way of checking only)? Upon braking does the car stop in straight line? I think if any/all of these are
not there then you can just top up air pressure and that's all. Waise, I suggest you should use Nitrogen in your car's tires.
Sir, When are we seeing the Onwer's log of your Nano? Aur kitna intezaar?
