Hidden Dangers of Tires that Look New But Are Actually Old

[JackFlash]

Seemingly new tires can actually be past an "expiration date" and pose danger to those using them. Known as "aged tires", their tread can actually separate while you're driving. At highway speeds, the results have often been fatal. If you have an unused tire that's over 6 yrs old, be wary of using it, according to this link from ABC News: http://abcnews.go.com/Video/playerIndex?id=4826897

Naalala ko dati sa Lancer Pizza ko orig tires pa yung nasa rear mga 9 years ng gamit. Bigla na lang na flat ng dahan dahan kahit walang butas or visible damage sa tire. Kaya dapat pag bibili ng goma dapat ma check yung manufacturing date ng goma.

Rubber deteriorates even when not used, so this is good advice.

If you have an extra set of tires, it's best to store them somewhere away from light. UV radiation ages tires too.

Don't forget to check your spare tire's age. If all of your tires are new but your spare is past six years old and already corroding in its well, you better pray you don't get a flat until you replace it.

Sa abroad we don't use tires that is already 5 years old from the production date, so here I do the same. Kaya pag nakakakita ako ng mga nagbebenta ng 2nd hand tires at surplus napapa-iling na lang ako.

We also look always sa thread wear, pag lumabas na yung embossed parallel mark sa main grooves it's time to replace it. BTW all tires have this embossed parrallel mark, if you look closer sa main groove ng tires pag inikot mo may makikita ka sa kanal na embossed parallel mark. Eto yung indicator na kailangan mo ng palitan yung tire pag litaw na at napupodpod na.


We also buy tires from premiere tire dealers like for example Yokohama main dealers to get the freshest production batch.

i remember one time when i noticed the car veering to the right while driving; inuwi ko kaagad, and upon inspection nagkaron na ng cracks along the sidewall ung front wheel. At the time matagal kasing natingga ung kotse sa bahay, as in once a week lang ginagamit for 4-5 years. Buti na lang di ko pinilit at baka sa EDSA pa ako nasabugan B)

Then again, the car also had 1 or 2 Goodyear Invicta tires that were still relatively OK after all those years. Nagcomment nga ung isang mekaniko, na phase out na ung replacement for that tire model, buti buhay pa B)

i also bought a pair of GT Champiro S'; they still looked OK when i bought it, though i had doubts that they were old stock. At the time i thought, 1.3K per piece? Hell yeah! After mga 2 years, bigla na lang pumutok ung isa while parked; no puncture holes or anything, nagcrack siya along the threads, luwa pati ung steel wires. Again, blessing in diguise at di ako nasabugan while driving.

La bang nakastamp na production or expiration dates sa mga gulong?

[speed unlimited]

Matroon nakalagay na stamp code sa goma kung anong year ito ginawa. Expiration wala ata.

[Mile2]

Lahat ng gulong may production date sa side wall, usually first 2 digits is year and followed again by another 2 digits which is the week number.

example 0947

09 is the year

47 is the week number.

Expiration is 5 years from manufacturing date.

Sa mga bumibili ng 2nd hand tires for spare tire, tignan nyo mabuti ang main groove minsan inu-uka nila para magmukhang makapal, re-groove ang tawag doon. Pag re-groove wala na rin yung worn out tire indicator.

sample ng date of manufacture stamp:



Manufactured 2008 work week 32


December 2007 bumili ako ng 1 pair of tires to replace iyong pudpud na. pero mga aroung 20% pa iyong tires. ng check ko ang spare tire ng 2nd hand ZZ namin, may buhok-buhok pa, parang hindi pa nagamit. ng i check ko ang manufacturing date, 2001 pa pala. 2001 nabili ng first owner ang ZZ na ito. Nakakahinayang kasi looks almost new pa. Now iyong isa sa mga pudpod ang spare tire kasi 3 years old pa lang itong papalitan ko.

Actually it's the other way around. The code should read "4709"

The first two digits are always the week number. The last two digits are the year number. So in the example above, the tires were manufactured on the 47th week of 2009.
