Check your old tyre tread. If out, it will be wear out one side.

What's your car model ?
Does the computer screen shows up your actual car model , or just without any car models ?

I sometimes wonder why wheel alignment jobs are promoted heavily (by vested interest groups) despite used tyre wear is NOT uneven from from one side to the other .

Proton Persona'09 fully stocked from factory.
The computer show up 'proton persona'07 (customized)'.

I saw that the tires wear out on the outside.
But I just rotated the tires few months back.
Not sure if it wear before or after I rotated.

According to computer (if the data is from OEM, IDK) , the toe-in seems ok . However the camber is out of range .
By stocked, do you mean to say no alignment adjustment was ever done before till todate ?
Theoretically , the out of range camber angle in your car is supposed to result in uneven wear across the tread width from one side to the other . Is this the case with your as-is used tyres , and do you have pictures to share ?
Btw, are you an aggressive driver in hard cornering , quick pick up etc ?

Have you change anything on the Absorber or Absorber Mounting?

I lesson learn on after change this 2 part and not redo alignment, after a year only notice tyre wear our uneven especially on the outer side. End up have to add Camber on 1 side.

Luckily when change tyre recently, the alignment not really out.

How regular is your tyre rotation on this car , every 10,000 - 20,000 km ?
Otherwise I wonder why the bold above , if you have regular tyre rotation .

Theoretically , the inside of your front tyres should wear out faster with your old alignment , not outside .

Do you see the inside of tyre wear more than centre of tyre , since you said outside wear is obvious to you ?

they show me the same shit. they charged me extra rm28. idk if i get conned

Yep, worn or new absorber /absorber mounting could alter the camber/toe-in numbers . But the numbers may still be within OEM range specs or it could also be out of spec as well , IDK .

Not sure by 'adding' camber on 1 side means shifting camber angle towards positive or negative , can anyone help elaborate or explain ?

However , adjusting camber angle of one side only I suspect it is due to the presence of a difference in camber angles readings between the 2 sides .

Having said this, on moments before adjustment, both different camber angles could still be within range , we don't know without like the computer screen shot by akatsukea above .

yeah, my friend also charged around that price, I think more reasonable. but got show us the screws

Basing on computer shot above by akatsukea , and if the specs given are valid then there should be uneven wear on the the tyres .
If the outside wear is more than the inside and centre of tyre thread , I would ignore alignment job .
However if the inside wear is more than the centre of tyre thread pattern , then I would surely do wheel alignment in akatsukea's case , never mind I am not a fan of wheel alignment .

I would say is after replace this 2 parts, cause the alignment out. Not sure is workmanship problem or ...
During that time, i did not take down the out degree. When see tyre wear out on side panic already, the shop advice to add, then just follow.

I got the feeling actually should be able to adjust back, is just they want earn extra.

Now I try go different tyre shop, i ask them change back my original nut, most of them say if no out, no need to touch or change. So using it few years until now.

I mean i dont mind the rm28.i get their package and chg 4 michelin tyres at rm740 including alignment but they tell me chamber is different adjustment from alignment and i have to extra pay rm28 on 1 tyre. i just want to know if im getting conned. haha

Hi, from the day after adjusting camber on one side to the day you recently change the tyre set you found alignment is not out .

May I know whether you do regular tyre rotation in between ? If so 10,000 km or ?

How many years or km during this interval ? 3 years ?

Hi Zeng, no. I'm not the person always do alignment as the price not cheap (well, for me only). I did not rotate the tyre as well.

My last install that camber until now is 3 years already, about 30K km.

Toe-in can be adjusted without extra cost in parts .

Since you paid extra and it has something to do with "nut" ,in the absence of wheel alignment screen shot here , I would speculate that computer camber reading is out of specifications which implies adjustment of camber angle is required .

However camber adjustment is not possible in your car design (what car model is this ?). Hence extra cost in camber nut parts replacement .

In other words, this tyre centre workshop has not conned you but did the job right , IMHO .

Me too is no fan of wheel alignment , neither do I practise tyre rotation .

From your experience here , total absence of periodic alignment and tyre rotation is all right for up to 3 years .

Thanks for the elaboration/clarifications .

I can't remember the degree, just know that the staff ask the boss advice, from their face reaction, seems like is an option to adjust. if not mistaken should be 1+ only. That's why from there on, anything also i take the photo for reference.

The nut itself not expensive, about RM20, plus the alignment RM35. That shop also weird RM15 for front wheel only.

I'm driving Persona 2011, same like your model.

Welcome, bro.

If not hit any big pothole, should be fine.

New car until change 1st set of tyre 3 years, no alignment all well.
2nd set is in between change that 2 parts, that's why make the tyre uneven wear.
After align back, now is another 3 years. My recent alignment is less than 1 degree, the foreman also say less than 1 degree can be ignore. I should save this RM20

Anyway just treat as pay for worry free. At least like you say i know about 3 years or more no alignment still not really out.
Btw, my last set of tyre last me 6 years!
