Changing rear camber is not possible with OEM suspension links. There are two paths for it - MPP’s currently available dual set of lower links for the rears or N2itive’s yet unreleased upper arm for camber.
I got my camber down to 1.6 on the rears from the 2.X on the OEM links.
Informative, and also critically important information.
If the rear camber isn't even adjustable on the MS, then there's no "alignment issue" to explain the massive, inner sidewall wear, correct? (Notwithstanding what the Discount Tire reps might say.)
Thus, since I'd posit that less than 3% to 5% of Plaid owners will ever see this thread, the only place left to assign blame for upcoming accidents (from high-speed blowouts) will be Michelin? Or will it be shared with Tesla for their possible failure to the forecast/test probable tire wear patterns with the default "Low" suspension setting at highway speeds (which helps improve range)? (But no one has yet reported a single issue with the OEM/base 19" Pirelli tires on the Plaid so I'm leaning much more toward a Michelin tire defect with these specific Pilot Sport 4S's.)
Here's my thinking as to what may become major legal action(s). We collectively have:
1. An
extremely hard to discover failure mode: the inside sidewall of the rear tires, which are visible to the average driver effectively "
never."
2. A
tire defect that manifests as one or both rear tire sidewall edges wearing until cord is showing, BUT some of which do
not "alert" to a potential problem in advance via a slow air leak (or, if they do, the owner just assumes that they've picked up a nail or a screw and just keeps adding air as needed). Even worse: frequent or chronic low pressure use likely exacerbates this latent tire failure mode as the contact patch shifts, there's more sidewall flex, which generates more heat (heat being the enemy of tires), which causes even more sidewall wear, etc.
3. Even at incipient failure, the vast majority of the tire tread appears perfectly normal, thus adding to the "just keep adding air until I have time to deal with this nail/screw/whatever issue later" thinking of the driver.
4. A Model S driver happens to demo the MS's performance potential to a friend and a rear tire comes apart at high speed, initiating a high energy accident as any car can be very difficult for the average driver to control in such conditions.
5. Very bad things result . . . at this point, it sort of feels like the Firestone tire/Ford Explorer fiasco from all those years ago, no?
Just thinking out loud here, but I
really wish Michelin would be proactive on this and get all the Pilot Sport "T1" tires off the road STAT.
