Michelin Pilot Sport 3

[pengyu]

pls let me know the outcome when u go to michelin..

 

[DareDan]

walau...tomorrow need to check all four tires de... hope nothing like this happen to mine...

 

[DareDan]

I check mine today... dont have this problem, maybe is still new.

 

[vr2turbo]

Maybe certain batch only...

Guys, there was an occasion many years ago with michelin too, the rubber start peeling off on its own, then go dealer said its normal bcos its a very good tire, hence "cengkam", hence, rubber peeling off.

The next thing, went straight to consumer tribunal, then the dealer ask us to drop the case then they replace a new set.

The problem was bcos those tires are kept for more than 2 years.

My 2cents bro!

Good luck.

 

[DareDan]

any one can confirm?

 

[vr2turbo]

PS3 users better check your tyres. But should be isolated case because many have used without problems.....

 

[YYC]

Having checked, my PS3s are all alright!

i dont rmb when i bought my ps3 and what mileage d. how u guys keep the record? lol est myb within 2 years gua.. tread level 50-60% before indicator

slightly off topic abit. i hear someone here sed he pump 210kpa, but i pump 270kpa front n 260 back, thats somewhere along 38, 39 psi

cuz lastime i pump 32psi like that, my dunlop bald habis the outside tread but the centre still damn good...so after i get the ps3, i pump it at least 260 like that. nowdays it wears out more evenly and the grip also better.

The wear could be caused by the ratio of natural rubber & SBR to produce the tire is out and the vulcanization (curing) process was not adjusted to the changed in ratio. All tires made need to go through a vulcanization process to improve the tire's properties so during the process, the polymers are all crosslink to each others to form chains. IF the vulcanization process was not adjusted properly according to the ratio it will affect the tires. The important thing in tires is the Dynamic properties which affect the flexing of the tires when it is moving. If the tire don't have good dynamic properties, it will crack and chip off easily.

Since , not all PS3 users complain about this problem, I believed this problem affect a certain batches of PS3. I've visited before rubber manufacturing plant and each time they received new raw material they have to go through lab test and adjust the mixture of S-SBR and the vulcanization process accordingly to the raw material because natural rubber from different country have different properties.

Hope the information helps..

You can check the manufacturing date on the tyres.....

Wah! 38 to 39psi, that is very very high air pressure. I use 250kpa for my 45 series, but if your level of pressure works for you, please carry on using....

In that case, TS should send back to Michelin for claim.....

250kpa? how to see? Usually I pump by looking at psi...for instance 31 psi front and rear 28 psi

British and US measurement leh! If you pump in psi, just use psi according to your figures.
Anyway, those petrol station pumps should have a guide between the 2 measurements.....

250kpa is roughly 36psi

Oh! BTW, keep front and rear difference by 2psi is good enough, as the front will heat up more, the pressure will go higher

Oh, I just follow the factory recommended pressure 31 Front and Rear 28 for BLM..

hmmm...the rears must be pretty light then.....

Seriously, tail happy if too fast on corners...that's why once i Skidded using Silverstone. XM2 also doesn't really help, but better than before...still got skid sound...

Need 15" upgrade liao.....

 

[Supra_Fanatics]

Got difference? 15" upgrade in terms of width as well? now using 185/60/14
Ngam ngam change tyre only...I think maybe next 2 years :frown:

 

[TitanRev]

SF, go do some math about the difference and go Google more info on contact patch...

195/50R15 against 185/60R14. Contact patch more by 10mm, 50 series, so stiffer sidewall, and in 15" got UHP tyres like PS3 that grips much better then the XM2.....
