I have goodyear RSA's, 3 tires look great, left front is half gone. Wear is even but I wonder why that tire is wearing so fast. Any ideas?
This is a 2003 MCS with traction control so I didn't think I was spinning that tire too much.

 

in the US you make more right hand turns and thus wear the front left
tire first. especially for someone like you that live in an area where
majority of the roads are straight.

why don't you slow down a little when entering expressway ramps?

 

HAHA now that's a lot of help......! LOL

To get back on topic, I would have the shop check out the toe on that corner of the car.

 

Front toe misalignment should affect both front tires about the same, since
you have to even the front toe settings out with the steering wheel to go
in a straight line.
Maybe underinflation, camber off, wheel imbalance, or worn shock on that corner?

 

LOL you haven't messed with alignment before on a car, have you?

 

yep. i would look into underinflation too. camber is non adjustable on
our cars so unless it was in an accident i doubt it's off that much.

 

You know you might have something there. Do you suppose the 80mph launch on to the freeway all the time could be it?
The vehicle is 90% freeway driving, never in an accident. I am taking it in for service in the morning to see if the dealer can notice anything. Thanks all for your help!

 

jokes aside, if you're racing onto or off right hand ramps all the time, it will
wear your front left tire.

 

My guess is that you are not getting off the gas early enough before poping the E-brake on your right turns.
