Rear tires showing excessive inside wear

My 2001 BMW 525i, has 125,000 miles--my tires (only have 60,000 miles on them) show good tread but just noticed alot of inside wear..appears the camber needs adjusting or could it maybe be the shocks/struts ? Anyone out there having a problem like this , I know BMW's toe out but this is abnormal/// Please Help TOM

This is very normal for a BMW. It is one of the factors that attribute it to great handling. Typically, the rear tires are adjusted for -2 deg of Negative Camber in a WEIGHTED alignment.

Depending on driving loads, this negative camber may be exacerbated if it was previously aligned in an unweighted position.

If you prefer longer wearing tires over more understeer handling, ask your alignment specialist to dial out the negative camber in a weighted alignment.

Also, worn suspension parts can affect the settings. If at 125K miles and still running on original suspension parts, I strongly suggest a suspension overhaul before performing the proper alignment.

BMWs don't toe out but have -ve camber set up.have your camber adjusted first and maybe check some of the multi link bushings for wear......

Not so. ALL cars can toe out if the car was lowered, a suspension part is bent/worn or due to an improper alignment. But yes, a NORMAL BMW aligned correctly has slight toe-in at the front and rear if within specs.

can you describe the wear pattern, ie how wide is the worn area, if very narrow then you probably need ball joints or other rear suspension componenets, if from middle of tire to inner edge then is probably just normal wear.

im sorry just noticed the 60000 miles on my tires comment. it sounds like you got your buck out of those tires, the last set of ultra performance summer tires I had lasted about 25000 miles.

#1 Cause: Worn REAR Ball Joints.
As others said, a REAR Suspension Overhaul will help:

#2 Cause: factory negative camber is -2 degrees or so. I dialed my REAR Camber to -1 degree and I like it much better that way.
Less inner tire wear.
If you have the gut to do this alignment at home, here is the DIY, enjoy:

Unless you buy Continental Extreme Contact DW. I got 14k out of the rears before I was just above the wear bars (I don't like to get them too low in rainy Seattle) Switched to DWS now....I expect considerably longer wear.
