Wow..after only i google what is toe-in, i understand your point now. Thks bro for your good tips..certainly will check on this toe-in things..

I thought for symmetrical tires, we should reverse the tire if the outside thread is shallow?

From the photo we can see the right side is bald while the left side is thick.

Of course don't do this on tires with rotation marked.

My car also the same, you can actually see that area is subjected to high concentrated stress and traction when you look at how the car turns into a corner



The photo is an extreme example but you can see how it affect the tires, the weight of the car went to the outside side of the tire.

So can i just reverse my tyre now so tat i can have it for longer time. As i mentioned, my car is rarely subject to hard cornering but i do travel occasionally thru Karak highway and the most doing like 100km/h..

Yeah, as long as the tire is designed to rotate both ways. If the tire have rotation marks then don't reverse it, because you will risk aquaplaning.

TS

Actually, you can't get a perfect worn tires...if you do, than great for you

My car also suffers from this...mine even worst, outer and inner worn off....even I so pump in more and do very regular alignment.

But end of the day, whatever it is, even if it worn evenly, at that state, you still need to change it....dun kid yourself...your tires are bold....change it TODAY!

And as for the uneaven wear, go do it at another shop.

Nowadays I see tireshop got alignment machine...but actually, do they really know how to do settings?

did you rotate the tyres every 5k or 10k KM?

anyway a good suspension or alignment wont wear off the tyre like this

and camber angle hardly go out of align unless got accident according to my workshop mechanic, he told me that when i go and change to adjustable camber

the only thing i can think of is the toe alignment

edit
hmm brain isn't fully awake it seems rofl

actually alignment wouldn't have anything to do with BOTH inner/outer (at the same time) wearing, it's just lack of air pressure

and yes, agree if the tire's worn out severely, best is to change.

also, you can read and teach the alignment shop yourself, just learn it up via google LOL

Yaya..i was looking for a new tyre now..this weekend ( only weekend i have time ) i will go to my regular shop to do some survey as well as try to ask other shop.
BTW..any good recommendation ard Puchong town...

I did do a rotation at 10KM if not mistaken ( everything done at Toyota SC ) but i always doubt whether they did the things that they said they'd done..
Accident, 100% free ( no bluffing coz i'm not trying to sell my car ) but masuk pothole ....who don't have this !!!

maybe you should bring your car to other workshop and check

i done my alignment and balancing in Kin Alignment in Bandar Sunway, their skill is good

OK..Kiln Alignment..i will check that out. BTW did they selling tyre with reasonable price ???

that i'm not sure, you have to ask them what is your tyres, but i dont have their number with me

tyre price around that area is around the same

Bingo. Right on the money.

Problem is Toe.

TS,

The thing is, the SC's alignment machine might be out of alignment as well. When was the last time they had it calibrated?

Your toe will never be 0.0 degrees. and this is why.

When they set the toe to 0.0 on the machine (assuming its correct), Also once you load your car, your alignment settings will all change. They will still take the car out for a test drive. and since our roads are fairly badly crowned (for water evacuation) they will manually compensate with toe adjustment to the right. Sometime that goes a little off and this is what you self.

I'm running 2.5degrees negative camber up front and 1.5 at the back and my PS3s lasted 40k km. My rear has toe out 0.5 degrees and it wears faster (don't ever use this setting unless you want a really tail happy car).

for the explanation..

My mechanic said, our road is not flat as balanced but slightly tilted to left side to adjust for water flow thus it'll effect the car weight being shifted to left by a small degree. So you'll get the threads on the left tires to wear out the most. Couple that with 0° camber you'll get more excessive pressure on that left's left side. So I asked then the tires should be \=\ lah? "Not by a high degree but slight, tapi ikut mana pun 2 tahun max ja aku jamin tayar ko ni tahan kalo drive mcm org gila."

Not sure what you are on about.


The reasons for abnormal wear are as follows. In that order.
1) improperly inflated tyres
2) out of spec alignment. ( which normally happen when you have worn out bushings or have hit something hard enough to bend some suspension components)
3) tyre failure (out of round, carcase failure)

Roads being crowned and your mechanics answer has little to do with wear..your car isn't 100% balanced left right to start anyway especially with you on board....unless as I posted, the alignment tech mucks it up when trying to set the car to go straight on a crowned road. ( which by the way, also concerns caster angle along with toe...but since caster angle can't be easily changed, they just tweak with toe.)

Tyres last 2 years? I haven't had tyres last more than 1 year in the past 8 years.

That means either you drive a lot, you drive hard, and/or you use very soft grippy tires.
I had tires lasted >4yrs before!
