Bro, if GY already call u, give them a chance lah. Make some time.

Even if u change the tyres already, keep the old tyres and show it to GY. Maybe they can still give u some vouchers that u can resell.

i went to GY just now. The guy used some gauge to check and said material ok.
then lift up the car, see the tyres, although lef right center all worn out, but can see there are sharp edges on tyres (sorry dont know how to describe).
so he said the tyres seem more like sliding then rolling, so is kind of alignemnt issue.


thank you guys for all your sharing.

So you rest your case?

The last time my Continental CC1 develops a bulge on the sidewall, it was replaced by Continental as a goodwill after some negotiation. It is definitely hard to prove whether it is manufacturing defects or my mistake but as far as I recalled, there's no sign of damage/scratches related to the bulge on tyre and rim.

Got sharp edges on the tread? as in like in the image?

Then should be toe-in or toe-out problem, which maybe is the tyreshop's problem as they didn't do proper alignment for you. If its really their fault, then the tyreshop should replace tyre for you.. not GY.

Here's some more picture illustrating toe, chamber, caster to better equip you with knowledge on alignment issue to argue with tyreshop if you want.. lol.

Ya, I am going to the workshop tomorrow. See whether I can get something.

Yes it is like what you show in your picture. That guy said it is toe in toe out problem.
Thanks for all the info. You really is an expert.

toe problem can cause tyres to wear that fast meh? 7000km is too extreme even for extreme toe angle and the car must have been shit to drive in those condition.

anyway, new types always at the rear please. dun go slapping new on the front.

are you sure??? i always heard ppl say good/new tyre should be put on front.

they are wrong. period. even tyreman make the same mistake

the short answer is that basically you want more grip at the rear, especially when it rains. for FWD, lifting off result in oversteer, and imagine your rear breaking loose.

oh yes my bad. Good/new tyre at rear is easier for car to self align back to straight in the event of loss control, and less likely to over steer..

New tyre should put at rear.

I have changed the front tyres . And now the steerling shake like crazy when speed reach higher than 80km per hour. Is this balancing problem?
I need to go to the shop agajn tomolo to complain.. I guess this is the last time I deal with ths shop.

shake did you mean the steering shake left right let right very fast? or the steering vibrate ..? ermm sorry i dunno how to describe lols . but i think should be more to vibrate, which is likely balancing problem. did you go back to da shop? how does it goes?

Is kind of like shake left and right. I went back the shop and they redo balancing, camber, and alignment.
Now not that shake but I notice the shake is most seriuos when speed around 90km/h, when speed reach 100km/h, it seem less seriuos.

My advice is to go to a different tyre shop. This tyre shop is obviously not giving a crap about your car or you.

I have the same feeling. I choose this shop because it opens on sunday and I sometimes only free on sunday. I guess I have to look for another shop.
I also learned that the mechanics there have target to meet. They have to push customers to purchase or change spare parts. Mean their job is not only fix your car but also make sure you buy or change spare parts with them. So I believe they will push customers to change spare parts like suspension, rims, tyres, brake, even though the parts still can use so that they can meet target.
I wonder are all shops like this? Or only this shop?

for my personal experience, i've went to 2 different tyre shop before, both also push me want to change this change that . the first time i still noob, i changed "adjustable chamber nut" 2 piece for RM 160 . to me i felt kena con. They'll always always try to squeeze more from my wallet..

here's the thing though, the reason for new tires in front is so that it can wear on the front, and then when you rotate it, the new tires will be in the rear.
if you put new tires in the rear, then you rotate it, you'll have an even worse condition tire at the rear.

granted, you can go with NEVER rotating the front to back and vice versa, then once front is completely worn, put the current rear to front, then new pair on rear. that works if you are unable to do 4 piece rotation and changing all 4 pieces at once.
do note that the best recommendation/practice is still performing PROPER 4 pieces (or even 5 if you wanna include the spare) of tires and then once ALL 4 worn, change ALL 4 pieces.

in the end, it is best that you know the reason for why things are done as such, and decide yourself

the thing is, one should be more diligent in rotation. to keep it simple, lets assume the most straight forward front-rear switch

say a set of tyres last for 30,000km, and assume a rotation schedule of 10,000km

the first rotation will switch the more worn to the rear, by the next 10,000 all four should technically worn the same and so you dun rotate. and you go on till the next rotation and it will be time to change all four tyres anyway.

even if one decides to rotate sooner, say at 8000km.

the second rotation comes at 24,000km which will bring the worn tyres to the back and the relatively newer to the front. then press on to 30,000km and all four would again be at the same wear rate and there is no need to put two new tyres at the front.

my point is, one can and should decide to follow a laid out plan for tyre rotation if he or she is really out to maximize the life of the tyres.

people who generally change two tyres and slap them to the front are generally just being negligent about their tyres and wait till the differences become too big to actually rotate properly.

i admit i am simplifying the matter here

correct, and if this is done properly, the topic of "front or rear" should never even exist and it's a straight rotate until 4 tires are worn down and change all 4

yup... dun go all miser and lazy on tyres. they are the most important part of your car.
