Pulling to Right Problem diagnosed


RPGR90s

Recommended Posts

2019 Edge ST with 105k miles. Original owner.

 

I installed a set of GoodYear Assurance A/S tires about 50k miles ago and they have been fine. Normal wear and they're almost due for replacement. 

 

About a year ago I noticed the car wanting to pull slightly to the right and they steering wheel being off-center to the left. 

 

  • Tire pressure normal (35psi) at all four corners
  • Alignment checked

Then I decided to just swap the two front tires from side to side and the result was that the car now track normally and the steering wheel is centered again. 

 

My theory is that the belts on the right front tire were wearing differently and causing the tire to drift to the right. My basis is that my father was an engineer at Uniroyal Tire for 40 years and he often talked about what happens inside a tire, even when the tread appears fine. 

 

So I'll be replacing the tires this Friday with a new set. 

 

Just wanted to pass this along in case anyone else is having a similar issue.

It is called "Radial Tire Pull". Just as @RPGR90s stated. If it still exists look up Firestone 500 problems.

Those were replaced with almost as bad Firestone 721. Luckily, we don't see as much as in the early days

switch to radials. Also fewer flats!

And never forget the TPC radial problems good old GM.
