Near end of lifespan

[Ambious]

Hi, anyone here knows how to identify if the tire is near the end of it's lifespan? Like any further will burst kinda thingy?

 

Recently saw some burst tires on the road kinda make me worried. I'm using 2nd hand tires, so I don't know how long was the tires used before. Still got plenty of threading though.

Huh? Recently I just changed my 2nd set of Hankook V2 and noticed that it was manufactured slightly more than 1 year ago....like that mean early next year I need to change tyre again?

 

Few years ago when I was looking for tyre replacement, I think a shop told me Michelin tyre offer 6 years warranty (if I remembered correctly..), and even show me a warranty certificate... I guess tyres should be able to last more than 2 years from the manufacturing date bah.

Should be shorter for us because of Sillypore's climate.

Furrynadz was pinpoint on the lifespan of a tyre, on-road. In addition to that, I recommend that the best way to ensure that your tyres are in working condition is to visit a tyre shop every 10,000km and do a wheel rotation and balancing. At the same time, you can visually inspect your tyres for any cracks or deformations, especially the inner side. Hope this help. Happy Driving!

i noticed the rubbers has this tiny spikes all over. someone told me when the spikes are gone, the rubber has hardened and due to change. dunno true or not

[Harrytan]

Those "spikes" are actually residual spurs from the injection inlets during the molding process. They are not to be used as an indicator for tyre wear. Some merchants actually shave off those spurs to make the tyre look nicer.

tire wear can judge from the thread. i heard its to see if the rubber has hardened or not. a hardened rubber has reached its lifespan no matter how much thread it has left. correct me if i'm wrong

[Harrytan]

No you are not wrong Toyo , If the the tyre is old and hardened, those spurs will break easily as a matter of course. What I meant is that alot of new tyres do not have those spurs to begin with as they have already been removed. The only sure way is to change a new set every 2yrs regardless of tread wear, to have peace of mind.

Hi Mic,

 

FYI, tyre had a shelf life of 5~6 years and depend on the storage condition. As for how to determine a tyre fit for use is by visual checking of any crack sign on the side wall and uneven wear on the surface (uneven wear may due to misalignment, incorrect tyre pressure (over/under pressure).

 

If all above is ok, tyre shld change when the groove depth left abt 1.6mm. Normal tyre groove depth is abt 8~9mm. Easy way to check if the groove depth is near to 1.6mm is by using the small triangular sign on the tyre side wall - follow the triangular sign up the tyre and u will find a step up in the groove area. This step up in the groove area is to use to gauge for 1.6mm, meaning when the tyre eventually come to flat with this step; mean you have to change tyre liao.

 

Cheers - Happy driving

FYI, latest studies have changed the recommendation to change tire when thread is 3mm liao..

thats why i said 4mm

below 4mm very sharp drop

[Ambious]

So how would I know if the tires are incorrect tyre pressure (over/under pressure)?

 

I had change the tire sizes and should be different from the recommended tire pressure from the manufacturer.

Hi,

 

To determine incorrect tyre pressure is to monitor the wear pattern on yr tyres, if wear more to both the edge indicates under pressure and wear more at center indicates over inflated.

 

Cheers
