    What are the wheel specifications of a EU 2.0 Roadster sport (or are all variants the same)? I am interested in OEM values of PCD, offset (ET), center bore, wheel nuts/bolts/lugs specs etc.

    5x110mm 65mm bore
    16x6 ET 25 front
    17x7.5 ET 38 rear
    All wheel versions have the same specs (US models at least).
    Aftermarket wheels with around ET 40 will work on both front and rear as long as they clear the calipers.

    I'm interested in upgrading my wheels, and don't particularly like the look of the Tesla standard Forged wheels. What else have people found (pics)?

    Just been told by my SC that they found a crack in a rear wheel and it has to be replaced. They are saying £858 for a replacement.

    I was quoted 21500 NOK (=2000 GBP) for a set of wheels (rims + winter tires + sensors)

    What type of wheels? The base cast wheels are $250-$300 a piece.

    You're the third person I've heard who had this problem. All of them had forged rims. I don't know what causes it.

    Pictures from the SC - who are strongly advising against welding it.

    I don't know what alloy of aluminum the wheel is, but aluminum loses a lot of strength after welding if it is not properly heat treated. The heat treatment might compromise the benefits of the forging. So it could probably be welded to look pretty, but it's probably not going to be strong.

    6061 aluminium alloy - Wikipedia
    Typically, after welding, the properties near the weld are those of 6061-O, a loss of strength of around 80%. The material can be re-heat-treated to restore -T4 or -T6 temper for the whole piece. After welding, the material can naturally age and restore some of its strength as well. Nevertheless, the Alcoa Structural Handbook recommends the design strength of the material adjacent to the weld to be taken as 76 MPa (11,000 psi) without proper heat treatment after the weld.

    If the question is to me then noting special, but UK roads are becoming a joke for potholes and I suspect I know which trip this happened on.

    Been years since I last shopped aftermarket wheels. Surprised to see how difficult it is now to find a decent wheel below 18" diameter. If I was in the market, I'd seriously consider something from CCW - Home - CCWheel. The Twisted Classic would be my pick.
