Uneven cupping or wear on the inside of front tires.I believe its toe setting. you set the toe on 2006 trail blazer 4/4 (HOW) ?raje

no vehicle make model. year supplied so the answer is generic but applies to most vehicles toe in is 1/8 -1/4 inch
caster 1 to 1 1/2 degrees and camber 1/2 2 degrees ( all measurements are positive
tire wear is the best guide to wrong alignment
wear on the inside or outside of the tire tread is alignment and toe -in
in the middle or on the outsides of the tread is pressure problems
wheel wobble at speeds ( 30mph up ) is castor adjustment, loose tie rod ends , ball joints and if the castor is approaching negative setting , will, not recenter the wheel after cornering
I suggest that you take the vehicle to an accredited suspension/ wheel alignment shop with experience on your make of vehicle and have it inspected
good shops will recommend that the rear is checked/ adjusted first as much front tire wear can be traced to the back being out

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.

You need to have a front end alignment done, and most likely you lower ball joints and possibly struts need replaced

You can not do anything

You need an alignment shop to check your car
for wear or damage.

Not a chain store that does alignment for $70.00

• If you wear either the inside or outside of the tire which could mean your camber setting is off and alignment is needed.

• If you have uneven tire wear in one direction (place hand over tire thread and run it forward direction, feeling for serrated sensation similar to a saw tooth) would relate to a worn shock absorber.

• Consistent wear on the middle part of the tire means you are over inflating your tire. Adjust pressure with a cold tire and use a quality gauge.

• Consistent wear at the inside and outside part of your thread means you are under inflating your tire.
• Uneven cupping around the tire means a suspension component is worn. Check all rubber bushings for condition and ball joints for play.
  

You have a front suspension part that is worn and/or need the front end aligned. If problem is in the rear you may need a four wheel alignment. If it was low air pressure it would wear the inside and outside edges of the tires.

bad bearings or bad alignment

the front end will need alignment kits installed that allow for the adjustment to be made to correct the tire wear, this has to be done on a alignment machine to set correctly, just eye balling it is not an option.

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.
