Always rotate la.
Make your tyres last longer.

Strongly agree with this. Its better to overinflate(reasonable) than underinflate. A lot of folks always associate tyre burst due to overinflation.
The higher pressure also works to your advantage in case where tyre pressure can't be checked weekly. Cheers...

Drilz mana?

Wait, are you using uni-directional aka Ultra High Performance tyres ?

If so, not sure if the tyres are pasang terbalik .

OP, care to provide tyre brand/model/size to see if it's UHP ?

Also indicates on pictures external sides and whether it is left side or right hand side front tyres .

Edit:Anyway it makes no difference to the underinflation issue at hand.

Yeah, my bad. The reason that i didn't cos it was less than 10k km. But I guess nowadays I should rotate at least once a year instead of looking at mileage.

My bad due to listening to an advise of an elder user to pump lower. It always bug me cos my front tyres sink abit after pumping. Its only recent months that i pump to the specification.

huh?

It is ok as silverstone powerblitz is assymetric , not unidirectional thread tyre.

My front tyres both inner and outer:

Possible underinflation and high speed cornering?...

No. 1 yes. No. 2...errr....I am often a careful driver, but there again, maybe i do corner quite fast. You noticed the side wear and tear?

Is it Michellen xm2? Looks like it. If yes, common issue, I ban xm2 long time ago. Some say still can use but I rather not risk.

Sorry Bro. Its just a humble Silverstone Powerbliz. I believe its my problem, not the tyres because my previous one Conti CC5 also have similar problem.

External edge wear at front tyres can be explained by physics as valid as brought up by some posters above. This phenomenon could be further aggravated by any one or all of the following scenarios , namely:
a )hard and sharp cornering at higher speeds and rougher road surface during cornering,which may or may not be the case with TS;
b )Inadequate tyre pressure or heavier loads/passengers even if one follow OEM recommended tyre pressures displayed at driver side door pillar, which surely applies in TS case here; and/or
c )Incorrect alignment in having too much toe-in , which cost some $$$ to do now, or while changing new tyres in future.

IMHO, spending some $$$ to rotate tyres today (and more $$$ if alignment is done simultaneously today) is not quite worth it for the potential savings (but is not definite saving, mind you) in getting marginal 'extra' 3000-5000 km out of (low'ish RM buying price ) front tyre life, IF there is really such problems which I'm not convinced.

But, that's up to TS really ..... which I personally won't recommend spending $$$ today other than increasing front tyre pressure from very low'ish 200 kpa (vs OEM's 220 kpa) to say 230-260 kpa, and then observe or move from there.

Edit:I'm doing 280 kpa with Wira and 300 kpa with Avanza 1.3 currently.

rotate must be in X pattern? should depend on whether tread directional?

dun mind me bashing you, but you took advise to lower psi (btw who recommend this and what reasons?) but isn't ok with tyres within 2-3years still okay to use?

from what others have mentioned, tyres look okay. inflate as recommended and rotate

Hi i just saw your msg. Well i got the advise from some old driver, the reason is to avoid over inflate the tyres, resulting in bursting. Anyway diff people have diff opinions though, this old driver might change his tyres very often, so he does not have my problem. Recently I asked another friend and he said best to change every year regardless of the mileage (which he did to his car). Like I stated earlier, I can afford to change tyres even every year (RM500-600 for 4 brand new tyres) but I am more interested to know the cause of it. It's like changing engine oil, i do know some people that still change every 6 months without giving any thoughts about whether it is needed or not; they just know that engine oil is not expensive and new oil should be good for the car.

Anyway from the comments here by helpful forumers, i had weighted all the opinions and i had decided to keep using for longer period before changing to a new one, not because i am stingy, but because my tyres can still be used.

The norm is x pattern. If i am not mistaken, my car's guide booklet also suggested the x pattern.

seem like the tyre did not have enough pressure? and traffic jam on hot weather? why does the treads look like they are melted and deformed?

Yeah, i suspect that it has not enough air inside it. Furthermore my car is parked 24/7 outside the main road without any shelter. The back tyres are extremely perfect though.
