What makes Whiteline different from OEM suspension components?

Whiteline suspension products are engineered for performance and durability well beyond OEM standards. While factory (OEM) components often use soft rubber bushings that degrade over time and under load, Whiteline uses advanced polyurethane and bushing technology that resists oil, heat, abrasion, and weathering. This results in sharper handling, more responsive steering, better load control, and significantly improved lifespan — without the harshness of traditional solid bushings.

Do I need a wheel alignment after installing Whiteline components?

It’s recommended to perform a wheel alignment after installation to ensure optimal performance and tire wear.

Are Whiteline Fixed Offset Upper Control Arms (UCAs) necessary for lifted vehicles?

They help maintain correct alignment and steering geometry after a vehicle is lifted.

Can I install Whiteline products myself?

Some products are DIY-friendly, but professional installation is recommended for suspension components.

Do Whiteline products come with a warranty?

Yes. Please refer to our warranty policy for details.

Tesla Model Y inner edge tire wear: camber, toe, or something else?

Feathered or scuffed inner edges usually mean toe. Smooth, even wear across just the inner shoulder usually means camber. Rear camber tolerance on this platform is wide enough that minus 2.0 degrees can be declared in specification while still consuming tires, which is why so many owners get a clean alignment report and keep wearing rubber.

Read the tire before you book anything

The wear pattern tells you the cause. Run your hand across the tread from outside to inside, then from inside to outside.

What you find	Likely cause	Fix
Inner shoulder worn smoothly and evenly, rest of the tread fine	Excessive negative camber	Correct camber, or fit adjustable arms if range has run out
Inner edge feathered, sharp one way and smooth the other	Incorrect toe	Alignment, corrected properly
Inner shoulder worn AND the car has developed a creak or vagueness	Worn bushing or ball joint allowing geometry to move under load	Replace the worn component, then align
Both shoulders worn, center fine	Chronic underinflation	Pressure
Center worn, shoulders fine	Chronic overinflation	Pressure
Patchy, cupped or scalloped	Damper condition or wheel balance	Inspect dampers, rebalance

Toe is the most destructive of these by a wide margin. A small toe error scrubs a tire sideways with every rotation and can ruin a set in a few thousand miles. Camber wear is slower and more gradual.

The number that explains most of the arguments

Tesla's factory specification for this generation of platform sets rear camber at minus 1.00 degrees with a tolerance of plus or minus 1.0 degrees. Read that carefully. It means a rear camber measurement of minus 2.0 degrees sits inside factory specification.

Minus 2.0 degrees of static rear camber will wear an inner shoulder. Not immediately, but reliably. So a Service Center can measure your car, report it as within specification, and be entirely correct, while your tires continue to disappear on the inside edge. Both things are true at once, and knowing that changes the conversation from a dispute about whether the car is faulty into a decision about whether you want control of the number.

Front specification for the same generation is camber minus 0.50 degrees plus or minus 0.45, caster 5.70 degrees plus or minus 1.0, front individual toe 0.05 degrees out and rear individual toe 0.20 degrees in.

The other thing most alignments get wrong

Tesla's service documentation requires 150lb of ballast in the vehicle while alignment is measured, and states that without it the real world accuracy of the adjustment is compromised. Most shops align an empty car.

On a Model Y, with substantial weight and a tall body, the difference between empty and loaded geometry is real. An empty alignment can read perfectly and then shift the moment two people get in. If you are on your second set of prematurely worn tires despite a clean alignment report, ask whether the car was ballasted. It very likely was not.

When it is not alignment at all

An alignment measures where the wheel sits when the car is stationary on a rack. It says nothing about where the wheel goes when the car is loaded up mid corner or braking hard.

That is bushing territory. As bushings soften and deflect, the wheel moves under load even though the static measurement is perfect. The tire is then running at an angle nobody ever measured. This is why a car can be aligned correctly, twice, and still wear tires, and it is the diagnosis most commonly missed.

Two tells that point here rather than at the alignment rack:

· The wear appeared or accelerated on a car with meaningful mileage on it, particularly past roughly 40,000 miles.

· There is a noise or a new vagueness in the steering alongside the wear. Wear plus noise is nearly always a

component, not a setting.

The parts that let you fix it properly

Rear adjustment. KTA326 adjustable rear upper camber arms give you camber control, KTA327 gives adjustable rear toe and KTA329 adjustable trailing arm setting. Given how wide the factory rear camber tolerance is, this is the difference between accepting whatever your car happened to be built with and specifying a number you chose.

Front camber. KTA368 adjustable alloy front upper control arms provide minus 3.0 to plus 0.5 degrees of adjustment, which covers a lowered street car through to a track setup from a single part.

Bushing accuracy. W56417 replaces the front upper control arm bushings with Whiteline synthetic elastomer, which holds its shape under the loads a two ton vehicle generates instead of deflecting progressively like rubber. KCA561 goes further at the front lower lateral position, replacing the bushing with a sealed spherical bearing so the geometry simply does not move. If you want the alignment you paid for to still be there in a year, that is the part.

Caster. KCA531 adds 0.75 degrees of caster with anti lift geometry, KCA532 adds 0.7 degrees. Caster does not cause inner edge wear directly, but it improves straight line stability and steering self centering, which reduces the small constant corrections that scrub tread.

Worn arms. If the wear is accompanied by noise, replace the arm rather than chase the setting. Whiteline supplies complete Model Y arms with ball joints included, covered in our guide to Model Y control arm replacement.

A sensible sequence

1. Check and correct tire pressures cold, and confirm what your placard actually specifies.

2. Inspect for play and listen for noise. Any noise means the component comes first, before the alignment.

3. Get an alignment, ballasted, with the numbers printed before and after. Prioritize toe accuracy.

4. If camber cannot be brought where you want it, the factory adjustment range has run out and adjustable arms are

the answer, not another alignment.

5. Rotate tires on schedule and re check geometry after any suspension work or a significant impact.

Frequently asked questions

Looking for more information about Tesla Model Y tire wear and alignment? Below we answer the most commonly asked questions

Why is my Tesla Model Y wearing the inside edge of its tires?

Most often excessive negative camber, incorrect toe, or a worn bushing letting the wheel move under load. Smooth even wear on the inner shoulder points at camber, feathered wear points at toe, and wear accompanied by noise points at a worn component.

Is minus 2 degrees of rear camber acceptable on a Model Y?

It falls inside Tesla's stated tolerance of minus 1.00 degrees plus or minus 1.0, so it can be reported as in specification. It will still accelerate inner shoulder wear, which is why adjustable rear arms are worth fitting if you want control of the figure.

Will a wheel alignment fix uneven tire wear?

It prevents further wear if geometry was the cause. It cannot restore a tire already worn, and it will not help if a worn bushing or ball joint is allowing the wheel to move under load.

Why do my tires still wear after two alignments?

Two common reasons. The car was aligned without the ballast Tesla specifies, so the measurement did not reflect loaded geometry. Or the problem is component deflection under load, which no static alignment can detect.

Do I need adjustable control arms on a Model Y?

Only if the factory adjustment range cannot deliver the camber you want, which is common on lowered cars and on cars built toward the negative end of the tolerance. If a shop reports it cannot bring camber into range, that is the answer.

Can tire pressure cause inner edge wear?

Underinflation wears both shoulders rather than just the inner one. If only the inside is worn, look at geometry or component wear instead.

How often should a Model Y be aligned?

At normal service intervals, after any suspension work, after a significant pothole or curb impact, and any time you notice pulling, an off center steering wheel or new shoulder wear.

Stop replacing tires, start controlling the geometry

Adjustable arms, elastomer bushings and sealed spherical bearings that hold their setting. Shop Whiteline control arms, camber bolts and suspension bushings, or go direct to the adjustable rear upper camber arms.
