Wheels and Tires

Replacing tires - front and rear or rear only.


This question seems to be a popular topic.  However, I just cannot reach the conclusion with the definite answer.  The search did not help, either.

My car needs the replacement tires for the rear.  I am trying to decide if the front ones need to be replaced at the same time.  It is a car with AWD, so there are some requirements.  

The depth of the tread for the front tires is currently 9/32 for both left and right.  Luckily, there are wearing out evenly.  The depth for the new one is 11/32 according to the manufacture data.

Tire Replacement on a 911Turbo

I have noticed quite a few different opinions on this question and wondering your thoughts.  This is regarding the replacement of a tire on a 911 Turbo.  I recently purchased a 2015 911 Turbo and just noticed that the passenger side front and rear tires have been replaced.  The car is certified and the certificate paper work provides the MM ratings of each of the four tires.  The tires are within less than or equal to 12% tread difference on each axle.  My question:  Is there a Porsche standard or otherwise that suggests when replacing one (1) Tire on a 911 Turbo?

I have a 2015 turbo with torque vectoring and all options. I damaged passenger side front and rear tires. I'm told all 4 tires need to be replaced if this occurs. Geico wants bulletin stating this before they pay.Where can I get such a bulletin/document?

I recently damaged passenger side front and rear tires and wheels on my 2015 911 turbo. It has torque vectoring and all suspension options.

Dealer tells me that I need all 4 tires replaced if this happens. My insurance company requires a bulletin or document from Porsche stating that the dealer is accurate in his recommendation. before they will pay for all 4 tires. Where can I locate such a bulletin / document.


Thank you



996 TT changing to the 997 TT 19 inch wheels and tires

I have a 2003 996 Turbo and changed the wheels to the 997 TT 19inch wheels with 315/25-19 tires.  I have had these tires on for about 5k miles and there are no signs of the tires contacting the body but I noticed there is only about an 1/8 inch gap between the inside of tire and the body.  What is the minimum recommended clearance between the tire the body. Is this a problem waiting to happen?

2001 wheel spacers

I want to put wheel spacers on my car but was told that it may cause a vibration? 

Your thoughts?



Are 997 turbo s wheels forged?

I am surprised to have so much trouble finding the answer to this question, otherwise I would not bother you.  However, after reading about issues with various wheels, I would like to know how the OEM wheels for my car were manufactured.  Specifically, are these wheels forged, cast, or pressure cast?  Are pressure cast wheels as strong as forged wheels such as Fuchs when new?  I appreciate your answer, and if possible, any direction you could give me so I could find my own answers to such questions in the future.  Thank you, Van Cline
