Tesla Model X Tire Wear On “Very Low” Suspension Setting – Video

DEC 5 2016 BY ERIC LOVEDAY 8

On most vehicles, when the ride height is decreased, negative camber increases. This can have a slightly negative affect on tire wear, most notably on the inner portion of the tread.

To find out if this affects the Tesla Model X when the air suspension is set to “very low,” the folks over at “Now You Know” on YouTube conducted a bit of an experiement.

Here’s the video description:

“Welcome back! On today’s episode of Now You Know, we test out our Tesla Model X’s air suspension in very high and very low mode to see if it affects the wear and tear on our tires. Watch to see what we find out!”

As expected, tire wear is negatively affected…now you know.

Maybe Tesla can fix the problem.

An OTA software update from Tesla will fix this problem in a snap. :-\

Problem? I don’t think you’d want it any other way. The resting negative camber angle provides additional cornering performance above a vertical wheel setting, which is a natural combination with the lowest suspension height setting. Even at the highest of settings, the suspension design causes the wheel to swing into negative camber angles as the suspension is compressed.
It’s nice to be aware of what your settings do, but it’s surely not an oversight that Tesla built the system this way.

Yes, apparently Tesla uses a negative camber angle as the factory setting, previously reported on the Model S, so no surprise if it’s the same on the MX.

Some have complained of excessive tire wear on the MS, perhaps related to this camber angle.

My question is this: Couldn’t they reverse which side of the tire faces out when the tires are rotated, to extend tire life?

Only 8,000 miles out of a set of tires might fly with the well-heeled Model X set, but somehow I doubt that more frugal Model 3 buyers would be happy about buying new tires every 8,000 miles. Tesla can’t offer this feature on the Model 3.

I would think playing with the accelerator pedal has MUCH more to do with tire wear on a Tesla product than ride height.

This -is- a surprise, as I didn’t realize that camber would be adjusted when height ‘dropped’ for apparent aero-goodness. Whatever some racers may perceive as normal, that’s racing, Not driving merrily down the interstate to gramma’s.

Seems a ‘sport’ adjustment would have served any racy you desire, but for mom & pop, we only need aero-improved mileage (and correct tire wear) as racing about in the MX is a limited proposal at best. On the other hand, mis-aligned (for apparent performance goodness) tires at X-hundred a pop can add up painfully if you keep buying the directional HP version, bad enough to have the originals wear out prematurely.

makes ya’ go hmmm..

Pretty much all car suspensions (except live or dead beam axles (trucks) or trailing or leading links (Citroen 2CV, original VW beetle) gain negative camber when the suspension compresses (bump travel) and go positive when the wheels droop. This is due to the geometry of the physical suspension linkages and pivots. It’s not tuneable other than by physically replacing suspension members with different ones or moving the pivot points. Different suspension designs have different camber change curves, but some amount is always designed in as it is highly desirable. Tires work best when they are perpendicular to the road surface or slightly leaned in against side forces. When a car goes around a corner the body rolls toward the outside of the turn which also tilts the tire outward. This is bad. A good suspension will gain negative camber proportionally to compensate for the body roll so that the tire remains vertical. It does this by having the compressed outer suspension go negative and the drooping inside suspension go positive. The effect is that the outer tire remains vertical. When the ride height changes the same geometry is in effect, if the suspension is compressed (lower) camber becomes more negative,… Read more »
