Tire Expiry

[Hayward]

Most of us may not be aware but one of the most important part of our ride needs a second look. Check this out.
Vehicle tires have a 4-year validity period from their Date of Manufacture (DOM). Thereafter, the tire expires and may burst whilst in use. How to find out whether your tire has expired? Check for a stamp like this: (*2603*) There is an asterisk at the beginning and at the end of this serial number. The first two numbers 2 6 will tell which week of the year has it been manufactured.
NB: One year has 52 weeks. The last two numbers represent the year of make. Therefore, *2603* shows that the said tire is manufactured in the 26th week of the year 2003. *2699* this shows that the tire is made in the 26th week of 1999.
Check all your tires for safety purposes. Do not use expired tires. They are likely to burst (especially when running in hot weather) because the rubber component may have hardened and cracked

Yup, kaya when you buy brand new tires, make sure they're not selling you old stock, coz kahit bnew yan, if nearing 4-5 years na sya nakastock bubukul din agad yan.

Oh, di naaddress ni Hayward.... yung pinost nya is the way to read when it is manufactured, the tire rubber will "expire" 3-4 years after that.

I was checking out my cousin's van that had Goodyear tires, and I can't find the number/date you guys are referring to.

Is it stamped on the tire itself, or can it be found on the sticker that is attached to the tire when it is new? Can someone post a pic of this number so we can have a better idea of where to look for it?

[theveed]

mikey: Meron po lahat AFAIK as long as steel belted radials... Not so sure sa mga "tube type" na gulong.

It is stamped on the tire itself, along with all the other tire info sa sidewall...

Hanapin mo nalang ang 2 digit year number sa dulo... malamang yun na yun.

Iba iba kasi sa mga tire manufacturer ang date stamping format, but the week and year is a standard... May mga prefix numbers lang mga ibang manufacturers.

Eto pa from TireRack.com

In addition to the tire's brand and line names (tire model), there is a lot of information provided by the manufacturer on the sidewalls of the tires they produce. Some of the branded information provides the tire's basic dimensions and identifies the week it was produced. Other branding lists the types of materials used internally to reinforce the rubber, along with the tire's maximum inflation pressures and loads. And others confirm the manufacturer certifies the tire meets various industry standards and measures up to the government regulations of the nations in which it will be used.

While not all information is branded on every tire, the illustration includes the typical information found on many tires.

Rolling your mouse over any of the descriptions will highlight the appropriate branding on the tire sidewall illustration. Clicking on selected descriptions will link you to a page providing additional details (where applicable).

Sir mikey sa ibang brands like Bridgestone, these are in ALPHA-NUMERIC format. Example: *AAA4405* and these are found on the sidewall of the tire. Yung ibang brands NUMERIC format lang.

In this pic, the date is on the bottom (upside down), sa dulo where it says something "2305" na may parang circle. Right above the word "FORCE" sa gulong.

Is all tire will expired on a 4-5 yrs period? Bka meron nman ibang brand na matagal ang expiration date nya. Paano kung tire mo ay umabot ng 5 yrs at ok pa naman, need mo na rin bang palitan dahil expire n sya, for safety reason.

[theveed]

Typically 6 year max, almost all tires are made of the same materials. Read the links above.

Basically, yes, it should be replaced. Just like engine oil, even if you only used the car for 100 kilometers, but it has been there for over 5-6 months, it has to be changed.

How come only 1 tire has this marking? The other 3 tires have just blanks on those spaces.
