Is it normal to have tire wear primarily on the inside of the rear wheels? or is this an indication of an alignment issue? Just changed over my summer tires to my winters and noticed fairly significant tire wear on the shoulder area only, on both inside rears. 04 CTT, any advice is appreciated, thanks, Troy

One more question, when I get above a certain speed an indicator comes on and says above limit, does this do anything (speed limiter) or can it be disabled in any way?

 

What setting do you normally drive in?

What setting was the car aligned in?


If you have it aligned at the "normal" ride height and then drive in the "low" ride height most of the time then you will be driving with more camber and wearing the inside of the tires faster.

 

Definitely not normal.

If you are talking about the round warning that shows up, that can be disabled or the speed adjusted.

 

How do you disable this warning (it's quite annoying-I think it comes on around 125-130km-h) Is this just a warning or does it actually do something to hinder gaining more speed or limit top speed?

 

I believe the suspension is usually in the lowest setting (other than loading level), guessing that's where the previous owner had it most of the time. Should I just do a four wheel alignment in the lowered setting vs normal? How much of a difference in ride height and camber are we talking here?

 

snzuloz, did anyone happen to PM you on this question?

I am taking car in for alignment tomorrow AM, as my inside rears are wearing faster than anywhere else, but I drive in sport mode on lower suspension setting more often than normal. I read a post by bubbam jace, seattlebum, and others, and it looks like they can do it in low setting, and you have to "lock" the air suspension, but not sure how you can lock it in low. ???

Just trying to determine where to leave the suspension on the suv when doing the alignment.

 

If you are taking it in for the alignment make sure to tell the people doing the alignment that you primarily drive in the lowest setting and to align it at that level. Also make sure to fill the fuel tank and adjust all tire pressures etc beforehand. The suspension will stay in the setting that you set it at and as long as no one alters the switch it will be fine. How bad is the tire wear you have?

 

Depending on if they lift it from the center body are or on the suspension, you may not have to lock the suspension. If you need to there is info in the manual. I believe that you just hold the lowering button down in loading mode for 30 secs or something and it flashed locked. Lift on the suspension then you do not need to lock it.

 

Two different things happening here, if you want an alignment it is performed with the wheels on the ground and at operating weight. If you need to lift the vehicle with a hoist or jack than you need to lock the air suspension otherwise the air shocks let the suspension travel to the maximum travel they offer. Holding the button (height adjustment) forward for ten seconds locks it in place in the setting it's currently at.

 

Thanks guys... off to the place now. Let you know how it goes.

 

I was told by multiple places that the car must be aligned in the "normal" mode. Does anyone know if this is true or not? Would love to align the car in the "Low" mode especially since I have a lowering module that definitely make the tires wear on the inside...

 

Most shops will default to this answer to cover their butts. Mostly because the techs only make the alignment numbers match the specs but don't actually understand the suspension. (much like matching the little number on the speedometer to the little white sign on the side of the road without further understanding of what it really means)



Find a GOOD independent shop that actually understands what they are doing and you should have no issue. I have run into this problem a lot with modified suspension cars, race cars, Jeeps etc.
