aussie aligner Posted February 9, 2011 Report Share Posted February 9, 2011 I fail to see how power steering wears the tyre, i've had this argument for years.... It's a myth like brake rotors? how come this "phenomenom" doesnt exsist on cars pre power steer? Quote Link to comment Share on other sites More sharing options...
Tony Posted February 10, 2011 Author Report Share Posted February 10, 2011 Look at it logically...... Power-steering does not change the achermann angle or lock angle. If the driver is able to turn the steering assisted, dragging the tyre then why doesn't the inner wear when turning on the opposite lock? Also wear is uniform around the circumference of the tyre, how come? Quote Link to comment Share on other sites More sharing options...

But I also agree that the presence of power steering leads to greater possibility of abuse of tyres. Every day when I reverse from the garage, I do a three point turn on the drive in order to face forward when going onto the street. When I think of three point turns without power steering, they were much more gentle affairs. I would feel through the steering the point where the steering angle was comfortable and matched the level of forward/reverse motion so that the wheels moved easily and with little scrubbing. Now, there is almost no feel and I can easily change the steering angle with little or no forward/reverse motion on the vehicle. It can't be good for the tyres?

Rich Posted February 11, 2011 Report Share Posted February 11, 2011 I have to say I've noticed this going from the Mondeo with power steering to the Escort without. Rather than steer when the car is stationary I get it moving first and what aussie said above about turning the wheel when you stop at a junction, I do that now. I can't agree with it wearing the tyres though, I have had several geo's at WIM and although I have some inner wear from the car being lowered there is none caused by the power steering IMO. However, could power steering be causing the whole tyre to wear more quickly as we turn the wheels in a stationary position? Quote Link to comment Share on other sites More sharing options...
