    I'm almost religious about maintaining front and rear wheel alignment. I also have the adjustable rear camber links which enable setting rear camber very close to -1.00.

    Here are the latest tire wear reading from my service center. Totally even -- this is with about 30,000 miles on this set of tires.

    Measured tire tread depth at:

    (Outer) (Center) (Inner)

    LF: 3/32 3/32 3/32

    RF: 3/32 3/32 3/32

    LR: 3/32 3/32 3/32

    RR: 3/32 3/32 3/32

    245/40R-20 Pirelli Cinturato P7 All Season Plus XL. They were replaced this am with 245/40ZR-20 CONTINENTAL EXTREMECONTACT DWS 06 XL. Go in next Saturday (not to Tesla) for an alignment

    What toe settings do you use for the fronts as well as the rears?

    I don't have a record of the order but if you do a search for "adjustable rear camber links" I'm sure I posted the info.

    I have an April 2014 S85 and have 46,400 miles on my original factory 19" tires (I have a different set for winters). Only annual services as it relates to the tires. Quite happy with the miles.

    Just got my shipment from BBC Speed today! I have 2014 P 85+ and my rears tires wouldn't even make it a summer season with the staggered 21's - the car would eat the tires like a fat man eats donuts! I can't wait to get the links installed (once I pick them up from the Post Office).

    Confirming settings for P85+ - dropping the suspension to low then:

    Front Toe 0.4
    Rear Toe 0.18
    Rear Camber -1.00

    Correct?

    I just replaced my tires. About 30K on the primacies (34K total with about 4K on the 21" continentals). I had an even 3/32 on all 4 tires in-center-out. Had probably another 4K in them but I just started doing weekly snow trips and the Primacies are rated pretty bad in the snow plus they were getting thin on the tread side.

    My rear camber is -1.5 to -1.6 as of this morning when I got my alignment done. I'm a little irritated that I didn't catch the fact that they didn't adjust my front left camber of -1 to equal the front right camber of -0.6.

    Just replaced my original Michelins after 39k miles with the Conti DWS 06's. I like them a lot. The originals were down to the cords and I knew I needed a new set when I could only barely keep with my friends 2017 911S. Will be ready for him next time!

    Have never done an alignment. Artsci, do you have any recommended alignment specs for a coil P85?
