2013 Tesla Model S: Monitoring the Rear Wheel Alignment

October 18, 2013

2013 Tesla Model S

You've already heard that the rear suspension of our 2013 Tesla Model S went out of alignment. For reasons unknown, the rear wheels slipped from 3/16-inch toe-in to 3/8-inch toe-out, which shredded the inside edge of the rear tires in dramatic fashion. Now it's got brand-new tires and the toe-in has been corrected, but we're still not sure when (or why) things went south.

So I recently hoisted the car up on our Rotary 2-post lift to add witness marks to the toe-link adjustment cams. I plan on lifting our Model S every 1,000 miles or so to see if it creeps again. I don't expect to see anything, but, then again, I didn't expect we'd be wasting our breath talking about chewed-up tires before we hit 10,000 miles, either.

Dan Edmunds, Director of Vehicle Testing @ 10,321 miles

    I would appreciate if we could "click to enlarge" the pictures in those kind of posts. Thanks for your great work!

    I'm not sure if I would trust an eccentric bolt to hold the alignment for such a heavy car. Would adjustable control arms be better?

    So far so good, it would seem. In reality what should have taken place is an investigation and permanent fix by Tesla, under warranty. Then checking your witness mark is just a verification of effectiveness, not something you're forced to inspect with every tire pressure check just to stave off more destroyed tires.

    @rock2155 - In the good old days with IL, Dan would have a ton of pics with 'click to enlarge' but now with Edmunds things are a lot worse around here as far as features. Sigh.

    @sharpend - They have the "enlarge" button on regular article and review, why not add those on these articles. Please don't reminds me the good old IL, I almost forgot already... Simple changes here can still make it better.
