Driver side toe-in

If it is only wearing on the inside edge your wheel alignment is wrong. The most common cause is the tyre is 'toe out'. The tyre isn't pointing straight ahead like the one on the other side. It is sticking out at the front edge.
Take the car to a good tyre and suspension specialist and get your 'tracking' and 'alignment' checked. They should check your track rod ends and suspension mounts as well.

1. What brand and model of tire was fitted?

2. Please describe the wear pattern on the front tires in more detail. For example is the excessive tread wear.....
A. Right across the face of the tread on each tire or
B. On the outside edges of the tread on each tire or
C. on the inside edges of the tread on each tire or
D. on both sides of the tread but not on the center section of the tread on both tires.
-----------------------------------------------------
B is normally caused by incorrect toe setting - toe in
C is also normally caused by incorrect toe setting - toe out
D is normally caused by tire pressure set way too low.

Faulty steering and suspension components can also cause abnormal tire wear for any component that affects the wheel alignment settings.

If you can provide a better description of the tire wear on each front tire you will get a better answer.

tires need to be balanced that will fix vibration. tire wear is a camber problem. get a four wheel alignment

When ever front end work is done, front end needs to be realign, the wear your getting is call toe wear, mean tire's are pointing out, and will wear tire's on inside edge, have it realign and that will take care of your tire wear problem.

inner tie rods

Be sure to have tires rotated every 5000-6000-miles. Walmart is good for that.
Outside wear is normal for fronts from the turns at higher speeds.
When tierod ends were replaced it is advisable to get front end aligned. Its not impossible to replace with minimum change but if settings were done with worn parts, new parts will change it.

You adjust toe with the tie rod ends they are threaded, the kind of method you describe will most likely make the problem worse, also outside wear is caused by the tilt of the wheel, that is called camber, on most cars the camber is fixed, the front end tech must do special mods to get this to be adjustable, some times drill out rivets, other time a kit must be installed.

the tires,check if theyre worn out,make sure you check the inside edgea,if they're wearing unevenly,replace them and get an alignment from someone you trust,make sure the caster/camber and toe are in spec.-toe and camber are tire wearing angles-camber the most-if the inside or outside edges are worn more,or when you drive and let go of the steering wheel,it tilts to one side,camber problem,make sure tires are inflated correctly,about 32-36 psi,check ur gas flap for bmw recommended pressures-u should be safe with what i gave you-so yeah,check tire pressures and wear-if tires feathered,too much toe in or out-this should take care of your problem,good luck

Unless there is noise or play when cornering sharply at low speeds (parking), the CV joint / boot is still ok. The joint does need grease in there and the rubber boot fitted properly very soon.

As the suspension is set, the axle does little more than provide drive. It doesn't affect toe-in or camber angle.

Camber angle (vertical tilt inwards) is a product of the suspension design, and often cannot be altered.

Weak front springs can also throw this angle out, as the vehicle sits too low.

Toe-in (forward point angle) can and must be set accurately, or you will skid about in wet weather depending which tyre grips more.

What is most important to you, is the tyre design, tread width and outer radius. Also the tyre pressures MUST be mid limit when cold on the front - otherwise excess wear will result.

Having tyres with a large contact area that are too rigid on the front will increase wear to the insides.

Also, it is good practice to rotate the tyres to even-out wear. Usually front tyres move to rear axle, and rears swap sides to front axle. If wear is uneven, pop them off and turn around before refitting. Some tyres you cannot do this with.

If you choose a tyre with a harder tread compound, or ones with "C" at the end of the code, these will again last a lot longer.

REAR WHEEL ALIGNMENT
TOE-IN : 0±2 mm (0±0.08 in.)
1. The rear suspension lower arm mounting cam bolt should be turned an equal amount on both sides during adjustment. Right wheel : Clockwise direction : toe-in Left wheel : Clockwise direction : ton-out Maximum difference between LH and RH : 3mm 2. The cam bolt should be adjusted within a 90° range left or right from the center position. CAMBER Standard value : 0°±30´ Maximum difference between LH and RH : 3mm : 0±2 mm (0±0.08 in.) 1. The rear suspension upper arm mounting cam bolt should be turned an equal amount on both sides during adjustment. 2. Install the left and right springs which have the same identification color. 3. The cam bolt should be adjusted within a 90° range left and right from the center position. TIRE WEAR 1. Measure the tread depth of the tires. Tread depth of tire [Limit] : 1.6 mm (0.06 in.) 2. If the remaining tread depth is less than the limit, replace the tire. When the tread depth of the tire is reduced to 1.6 mm (0.06 in.) or less, the wear indicators will appear.
