Crack on side wall...

[soup1207]

I didn't keep checking them since there's a sensor for tire. I check when the light is on...last time I inflate it to about 38 to 39 PSI, the standard is 35 for this tire.

Would it be part of the factors also? Or only under inflated cause this problem?

Thanks,

Ricky

Overinflation can lead to problems as well, but 4 or 5 psi over would not be enough to cause that type of failure.

My last time inflat my tire...I remember the psi is at 2x....not sure why the sensor light up only when it's so low.

How often should I check my tire ? Which level would start harming the tire?

Thanks,

Ricky

With how light the Yaris is, you would need to be at least 10 to 15 PSI over the tire's recommended pressure before you would potentially hurt them.

Thanks all. I think I will go for Sears since most other place are about the same in final price. Cooper seems like a good brand...?

IMO, I do not count on the light to keep up with my tire pressure. I check them once a month. Any drop in pressure causes more heat which is what caused your tread to separate. Best of luck.

Thank you very much, I will check them monthly from now on, not a difficult job anyway.

I have a further question about this tire. My father said, "if they are not retreaded tire / refurbished tire, they should be fine." Because the rubber is made all at the same time instead of combining an old tire with new rubber (tread). He means it's not likely to suddenly shred a big piece of rubber and broken down on the road.

Is he correct? (he's not auto technician, but his statement seems a little logical)

Question 2 - Do Good Year or other brand make retreaded tires? Is the one I am currently using is one of those? It's Good Year Eagle something (They are the tires come with my car on the first day.)

Thanks so much for all of you sparing your time with me.

Retreading is not common for car tires and would never be used on a new vehicle from the factory.

I would not expect the failure mode from that type of cracking to be shedding a large chunk of tread. I would expect it to eventually lead to an air leak or eventually a blow out, when the crack suddenly deepens.

I see... Thanks very much for your advice. A large chuck of tread shedding is what I worry about.

So those tire I purchased with a regular brand name like Good Year, Kelly, and so on, are not likely to be [re-make] tire. Thanks~!!
