Well there are some arguments all over the world too..
Are stretched tyres legal and safe

One thing for sure, proper recommended fitment is already proven safer, and stretched fitment would never be safer than recommended one as it's not yet even proven to be safe in the first place! So if some one asks me like the TS did in this thread, I'll surely give the better answer which will be safer, and would never recommended something that's not yet proven safe nor less safe. I would never want to be responsible giving a recommendation that later can become detrimental to others. If however the person still ignores it, then that's his/her choice and not my fault. :)

Stretch will undermine the durability and safety of tyre especially at the sidewall as the underlying construction has a elastic limit.

Sidewall Separations/Bubbles

Lea esta página en español

Pneumatic tires are made of specialized rubber compounds reinforced by plies of fabric cords and metal wires. While most rubber compounds can be stretched easily, the underlying fabric cords and steel wires actually define the tire's shape by limiting stretching. In order to bond these dissimilar materials, the cords and wires are coated with adhesives and/or rubber before the other components are bonded to them during curing.

A strong bond between these various components is necessary to provide the desired durability. However the strength of the bond can be reduced if 1) any of the components are contaminated during manufacturing (resulting in incomplete bonding), or 2) components are damaged in service due to use while overloaded/underinflated, or by impact with potholes, curbs or other road hazards that pinch the tire between the rim and the road, or simply stretch the rubber beyond the elastic limit of the underlying cords and wires.

Past experience indicates that a sidewall separation/bubble caused by component contamination or incomplete bonding during manufacturing will appear within the first six months of service. Fortunately these separations/bubbles typically appear when they are small in size and before the tire's strength is substantially reduced. However since typical tires roll about 800 times every mile and the air pressure inside the tire is greater than outside, tire separations/bubbles that are unseen or ignored will continue to grow in size, further reduce strength, often generate noise and vibration, and ultimately lead to tire failure as the tire stretches under load (similar to the way that continuously bending a paperclip back and forth will cause it to weaken and break). However there is one last thing to remember; while a separation/bubble early in a tire's life is usually associated with a manufacturing condition, even a single, significant impact with a deep pothole or sharp curb can cause a new tire and wheel to be damaged.

If the sidewall separation/bubble appears after six months of on-vehicle service, prolonged driving on overloaded/underinflated tires or a road hazard are the most likely causes. However it may take weeks or months after an impact for a separation/bubble to appear as the damaged or bruised area continues to weaken. Unfortunately the time differential between the impact that caused the initial damage and the delayed appearance of visible evidence often means that the driver has forgotten about the impact that damaged the tire in the first place.

The varieties of possible causes make it necessary to inspect the tire while mounted on the wheel (sometimes the wheel will show impact damage adjacent to the separation/bubble), as well as to dismount the tire and inspect the condition of its innerliner thoroughly. Sometimes it is necessary to return a tire to the manufacturer's inspection center where it can be dissected before the actual cause can be determined.

While taller profile tires can be damaged by the more severe impacts with deeper potholes and sharper curbs, low profile tires mounted on large diameter wheels are the most susceptible to this type of damage. The driver of vehicles equipped with low profile tires should make special efforts to avoid potholes, curbs or other road hazards.

haha..
moral of the story..
just stick to stock OEM..
reliable..practical..nil headache..and safe..
no need modi or else..

Yup, If stretched is safe why then manufacturer give correct fitment details and will void warranty if out of specs...

Well I think we also never suggest to always stick to std OEM and not mod at all bro. :)
Most of my cars also got some mods and upgrades like suspension, rims & tires, brakes, performance, audio, etc2. but all done to improve the cars and benefit the driver, none will be detrimental. As long as the mod is done properly within the technical specs and capability of the cars and the equipment, then it should be fine.

hahaha..
chill la broo..
seems "like" u "bang" my previous 2 reply
jus like i said b4..
just sharing my thought and few months experience for such "tyre strecth" things..
furthermore, im not forcing anyone to do such things..
anything we did, sure there is pro and cons rite..
hahaha..
cool daddy..
im just noob here..

Hahaha, I don't "bang" your replies. I'd rather bang my head listening to heavy metal music. I just try to correct and clarify if I saw something not right.
IMHO some things got pros & cons, some got pros only, and some got cons only, not everything got both.

Cool daddy...hmm yes I'm a daddy but don't call me that coz I'm not your daddy and if heard/read by my wife later can cause big suspicion and fight in my home.

Cheers dude.

stance and fitment philosophy = haters always hate our scene..huhuh

I don't hate your "scene" or your "philosophy". I don't even care if a person likes to screw cows (which is illegal by the way). Just don't do it in a way that affects me.

If you are at an auto show, I will give a thumbs up to your car with its "stance" and its "philosophy".
If you are driving on public roads, please make sure your vehicle is safe, else I will give a big F**K YOU.

YYC explained why it is dangerous. Cars, rims, tyres are all SCIENTIFIC, its not a philosophy. You stretch the tyre beyond its designed range, it will fail.

And as I've said before, you can bang a tree if you like, other road users are innocent. The roads don't belong to your father.

80km/h doesn't seem fast, try imagine something hitting you at 80km/h.

For example, THIS

Haha..chill bro..
Even oem car acting like a damn..
Based on the above post,u quote my reply..
And stated me as "you"..and a big FCK??
Chill bro..
I dont even raised any issue..
As i mentioned b4,just SHARING MY THOUGHT..
And
And i respect others comment without arguing anything..
Everyone has their own mind set..
I respect ur comment but plsss...dont say FCK YOU to me..
Strecth tyre thing came from hellaflush/stance scene..
Meanwhile,this things is not origin from malaysia too..
Dont FCK ME..maybe u can make a inquiries to Fatlace/Illest for this strecth tyre issue..
Again,i just sharing my thought..not forcing anyone to follow it..

I share one video..
https://www.youtube.com/watch?v=cq7hcGWTsBo&feature=youtube_gdata_player
Most of them having negative camber..wide rim..and stretch tyre..
Maybe u can FCK them tooooo

Mod sure have as in upgrade but as mentioned by you should be within specifications....

Oh that poor tree has a right too la, bro! LOL

 

[TitanRev]

zul, since you are on stance. I'm just curious and wanted to know really badly....with such setting, do you dare to corner really hard or do touge or spirited driving or bring it to track? just wanted to know

 

[esthapo]

Hahahaa don't think they can do that Titan. saw many stanced cars go slow on corners & the wheel arch shredding the tires...never in my life those car able to pass my car coz cant drive fast on corners I believe...even straight line also sometimes slow due to uneven road...faster u drive, faster the tire shred I believe...haha

He only meant to say it to those who disregard safety in doing the mods, not the trend in general. It goes beyond stance. Any mods should be done properly, be it for speed or stance.

 

[vr2turbo]

Agree, any mod done should be safe also.....

I cannot stand watching such video. Feel sorry for the cars, and I find it odd that the owners are willing to torture the cars and themselves to such extreme. Anyway it's their money, their cars, their joy or pain, I don't care as long as they don't affect me if I meet them someday on the road!

i have done the stretch tyre before..before my car tyre setup is 195/50 r16 on a r16 with 7.5 jj on rear and this is happen when i drive very fast with this tyre

Actually 195 on a 7.5jj is still borderline just before start stretching. I had once used such fitment before for a few years without problems but not ideal.

Just because you didn't have any problems doesn't mean its safe, you were just lucky. Seriously dickheads who wanna go "stance" and shit, it is absolutely fine, just do it at your own driveway at your house, or go do it at a private track like sepang. the road don't belong to your father.

douchebags.

think about it, it takes one scumbag with "stance" and shit to blow a tyre on a highway, take out 7 or 8 cars, get 2 people killed, and the government, JPJ and police will make ALL car modifications illegal because it is unsafe, and I won't blame em.
