V0v4ik Posted November 18, 2009 Report Share Posted November 18, 2009 I welcome all participants of this forum! I am a novice here, so a few words about yourself. I have a few (6 years) experience in the post wheel alignment (Bosch FWA 510) and the craving for knowledge, so I came to this forum. I was surprised because of wearing out of tires. It MB W 164 ML 500 4matic .Front 255/50/19,rear 285/45/19,shiny Pirelli scorpion zero asimmetrico (wrote the name, because it seems to me, that they also are the culprit of such wear.) For the sake of justice will say that wear of tires inwardly at such negative camber as he is done by MB (it is my opinion) simply inevitable. And in principle it confirms my practice of work with these cars, and with this auto in particular, but anyway, the run of tires succeeds to be led to to 40 000 –50 000 km Here run, made an only 20 000 km, and you see a result on a photo , and a machine was and is in specifications. I will say yet, that to setting of these tires other (unfortunately does not remember the name) stood and a run made a 50 000 km Actually question, what could such wear of tires be caused? I apologize my English. Thank you for your attention. Quote Link to comment Share on other sites More sharing options...
Tony Posted November 18, 2009 Report Share Posted November 18, 2009 Hello and welcome to wim The Ml chassis is naturally adjustable and even without the datum i can see the actual/ final positions are wrong, the wear is camber so it seems a reasonable move to set the cambers to OEM positions or move that particular chassis away from OEM as a custom setup.

V0v4ik Posted November 18, 2009 Author Report Share Posted November 18, 2009 Thank you for having responded to my question.I certainly know that ML camber adjustable,But it means that spesifications of my program is not correct? Quote Link to comment Share on other sites More sharing options...
Tony Posted November 18, 2009 Report Share Posted November 18, 2009 Ok let me put it this way..... There's a wear problem, what do you think is wrong? Quote Link to comment Share on other sites More sharing options...
V0v4ik Posted November 19, 2009 Author Report Share Posted November 19, 2009 Ok let me put it this way..... There's a wear problem, what do you think is wrong? Ok, perhaps in combination with the negative camber, tire is too soft (this is my thought). It seems that part A does not work (the pressure at the same time in the norm). And yet you have not answered my question. Specification not correct? Quote Link to comment Share on other sites More sharing options...
Tony Posted November 19, 2009 Report Share Posted November 19, 2009 The data is correct but doesn't work, i would dial out 30' of camber then monitor the wear. Quote Link to comment Share on other sites More sharing options...
V0v4ik Posted November 19, 2009 Author Report Share Posted November 19, 2009 The data is correct but doesn't work, i would dial out 30' of camber then monitor the wear. This is already done. And ironically, the owner bought the exactly the same tires. But still, what do you think about my thoughts (section A). It has the right to life? Because I am more interested in why so fast wear. Other tires wore differently, with the same geometry. Quote Link to comment Share on other sites More sharing options...
Tony Posted November 19, 2009 Report Share Posted November 19, 2009 Can you display the actual values now? Quote Link to comment Share on other sites More sharing options...
V0v4ik Posted November 19, 2009 Author Report Share Posted November 19, 2009 Final values are measured in a condition of calibration. In truth, it is Gl, but you understand me that I had in mind. Quote Link to comment Share on other sites More sharing options...
V0v4ik Posted November 19, 2009 Author Report Share Posted November 19, 2009 Understand Toni, at me on service to be 15-20 ML-GL (I speak about an air suspension bracket), and at ALL (it is not dependent on run) about the same specifications (+ -10 ’). Imagine, that you owner ML you do ТО1, I do check of alignment and I speak you: ' « that trunks would wear out in regular intervals, I should establish the repair complete set ». The car thus, as though is in specifications. What would you think, if were simply owner ML? I hope you me understand... Quote Link to comment Share on other sites More sharing options...
Tony Posted November 19, 2009 Report Share Posted November 19, 2009 What angles are the first three on the report? Quote Link to comment Share on other sites More sharing options...

Tony Posted November 20, 2009 Report Share Posted November 20, 2009 I just do not understand the question.

Tony Posted November 20, 2009 Report Share Posted November 20, 2009 I know it's going toe/camber/castor but the line of figures doesn't make sense, so if you can translate the wording, hopefully i can read this correctly. Quote Link to comment Share on other sites More sharing options...

Tony Posted November 21, 2009 Report Share Posted November 21, 2009 Other than the fact the front cambers have been reduced i cannot see a problem with the report, in this sort of case i would insist the owner maintains the tyres pressures then in 1k or so i would check for wear again and if needs be customize the calibration.

V0v4ik Posted November 23, 2009 Author Report Share Posted November 23, 2009 Thanks for your participation in my problem. From its part, I shall try to inform you, than it has ended. Pirelli- summer tire, the client (I think) has replaced with winter tire, therefore the answer will be more likely in the spring. Once again thanks. P.S Communicating with you, I shall learn English!

V0v4ik Posted November 25, 2009 Author Report Share Posted November 25, 2009 Today there came the client (to change bushings of the stabilizer),as promised here a photo with right from left Mileage 5500 km,pressure has been made 2.4 bar(yet the last time).At me claims are not present (on tire wear), I am happy! Continuation nevertheless follows... Quote Link to comment Share on other sites More sharing options...
Tony Posted November 25, 2009 Report Share Posted November 25, 2009 Looks good but as you say it needs monitoring to hit the idyllic positions. Quote Link to comment Share on other sites More sharing options...
