    Exactly. I had 401 Km remaining on my batter when I picked up my car. As per my request there was no test drive. I drove it about 4 KM on my test drive and when I got back to the tire shop I was now showing 408 on the range remaining. Thinking it might be because they new rims and tires are 5 lbs lighter on each corner? Anyone else experience more range when changing rims and tires. I highly doubt tesla left more range on the table and would of went with lighter rims if that's the case.

    I went with forged rims and RB brakes, a lot lighter at each corner. Stock tire sizes. The range difference at speed is consistently better, but so low it does not matter, like 1-2%. The ride and handling are much better,

    What size (width, offset) Lexani rims did you install?

    How much do your Lexani forged rims weigh?

    I got the Lexani Monobloc 102's, 1/2" wider front and back, 40MM offset. This is from memory, I will see if I can find the paperwork on them. I recommend doing the RB rotors at the same time. Very noticeable when you do both.

    No haven't tried doing anything like that unfortunately, I was just looking at it as more rim protection hate when they look like a rubber band on the rim with the rim edge exposed, but looks like you really have no choice on these as you won't get a tire wide enough to help with that and fit.

    Probably roll the dice on the Pirelli, or possibly the continental shown above, hadn't seen those previously so those look good as that's the highest load rating I've seen for a 22".

    Yes for the time being. Next round of tires I may bump to 305. Shortly after install I got a “acceleration reduced warning” but the car doesn’t really feel any different. Service appt tomorrow to see if it’s related or just a freak timing coincidence.

    I suspect unrelated. I can't imagine what sensor / system a wheel change affects beyond TPMS, unless you have some sort of weird diameter mismatch that is making the ABS sensors freak out. But even then I would think that the error message would more specific to ABS / traction control disabled yadda yadda....

    Correct you are. Main battery contactors failing no big deal. Parts ordered so I’ll just be driving around with this warning on the screen for a bit.

    Fun fact if you have aftermarket wheels don’t sell your factory ones. You’ll need to put them back on prior to any service which requires wheel removal. The SC will not touch aftermarket wheels.
