I was standing about 15 feet behind my 2005 RX8 that was parked in my driveway and noticed that the top of the right rear wheel seemed to tilt inward more than the left rear wheel. I am still learning a lot about suspension issues, wheels, tires, etc. and did some searching and reading to learn about this.

Seems to me (as a noobie) from looking at it that the right rear wheel has too much "negative camber". I just replaced the rear tires a few days ago and noticed that the inner tread on the right rear tire was more worn than the rest of the tread on that tire. The left rear tire was evenly worn.

What should I do? If I take my car to my local Mazda Service Shop, what would be the proper terminology to use to talk to them about this issue? Are there any "specs" on proper camber that I should know so if they diagnose that it is out of alignment, I can know how bad it is and follow what they might say about correcting the problem? In other words, what should I know and what do you suggest?

I appreciate your help. Don't want to wear down my new tire too fast.

 

They need to check your car on a four wheel alignment rack. They should provide you with a print-out of the before and after measurements as well as the spec for each reading.

 

I'd get it checked first. As for alignment specs, what do you primarily use your car for?

 

I don't track my car. I am not an aggressive driver -- though I will push the car now and then. So, more of a daily driver, I guess. Don't need hard cornering as a rule -- more want good tire wear. Anything else that would be helpful to know?
