引っ張りタイヤ=stretched tire
If your browser will display that, the term is actually "stretched tire", Hipari is just the verb and means stretch...
I found an article on it in hyperrev, back in the day when sidewall technology wasnt where its at today, it was a way of reducing flex in tires. But was found to be very dangerous on Front wheel drive cars, many racing classes in Japan banned fitments like that on FWD cars.
Its popular again though, mainly because drifters have found that "cheap" tires respond to the fitment like the old technology performance tires did, and because drifters are doing it, its now fashionable on the street. However the technology in new performance tires, makes that fitment obsolete in true need. The dish it creates in the centre of the tire apparently makes any tire useless on water, which would only make sense I guess..

well thats where we disagree.

thats cool. all I'm trying to get it is its not necesarily JUST FOR LOOKS. it does actually change how the car/tire reacts. although a lot of the time it is for looks.

Maxthe7man, thats some good info. thanks.

You're painting yourself into a corner...

For argument sake...
If you're running 14" x 7" rims...
And you're stretching 185 / 60 / 14 tires onto those rims...
Why aren't you running a 195 or 205 tire, which are matched for a 7" wide rim?
The wider tire gives you much more rubber to the ground.
It's also (arguably) can give you a wider "track".
All of those points to better traction.

So why are you running a wider-than-necessary rim for any given tire width?
You like running heavier than necessary rims for your tires?
Again, you're implying more unsprung weight is "better"?
Whatever the case, hipari is getting you no where versus proper sizing of tires to the rim widths.

You arguing stretching your 185 tire ends up being I-cannot-afford-the-wider-tire-for-my-rims, period.

Sure, I'm not denying you get "stiffer sidewalls" by stretching them.
My point is it's no performance advantage WHEN RUNNING THE PROPER WIDTH TIRES.

"fc3s pro"
better not argue or he will yell at you over the internet.

i run a stretched tire in the front because it makes for sharper turn in than with a large sidewall tire. "buy a low pro tire" you say. well if they made a 25 profile tire with a reasonable load index i would probably buy that. but i am already running pretty much the lowest profile tire available in my width, and so i stretch. I run a stretched tire in the rear because i like the smooth breakaway you get, less body roll before the tire releases, less body roll when the tire comes back in line, etc. im running a 265 front and 275 rear. any more tire and i start to have problems. too heavy etc.

that is why i like stretched tires over balooned tires.

thats cool. the thing is, I have 185/60 tires that still have plenty of tread, and I got 14x7 wheels. with the 14x7 wheel vs. the 14x5.5 wheel, the tire responded MUCH MUCH better. also, due to better response/a more predictable car, and can push the car harder at its limits and not worry as much about spinning or anything because I can feel when it starts to slide better than with the 5.5 inch wheels.

and as I said like a bazillion fucking times ted, I NEVER SAID STRETCHING TIRES IMPROVES GRIP, JUST THAT IT MAKES TIRES RESPOND BETTER.

Breakaway characteristics is a personal / subjective thing.
You can ask 100 people how they like it on their cars, and you can get 100 different answers.

Amateurs will like a more progressive breakaway, but the pro's will almost always take ultimate stick.

See above...

You're still arguing YOUR method is BETTER.


-Ted

stiffening your tire/sidewall wont make it faster, it doesnt make sense. and better is a subjective term...better in terms of? in all applications BUT drifting, its probably worse

i thought stretching a tire onto a rim was to reduce tire flex/roll. and to keep the car on the tread and not the side walls... but honestly i know nothing cuz i run normal fitted tires still at my track events but when i get the money i'll try the streching thing.

no, im not. like you said, response is a personal/subjective thing. it COULD be better if you care about better response. but if you don't, then its not better. its a personal decision as to if its BETTER or not. I'm just saying stretching does actually do something besides "look cool" you can decide if its better or worse or if you don't really care.

RETed.

Bigretardhead is not saying that EITHER METHOD IS BETTER. if you want grip. dont strech your tires. if you want it to be more predictable, yeah maybe stretching is better. That is all that he is trying to say.

the only thing id be worried about w/ stretched tires is if you're running really low profile tires that you have a really high chance of nicking or having something on the road running up against the lip of your wheel

"More predictable" is also subjective.
Please reread my response.
Handling is subjective to each person's tastes.
How can you claim YOUR idea of what is better will work for OTHER people???
This is my beef.

I'd like to know how much real driving experience do you all have???
One this I learned is that not eveyrthing that works for you will work for someone else...


-Ted

I didn't say its better or if you should like/dislike it. I just said it changes the way the tire acts. it makes the sidewall act as though its stiffer, which makes the tire respond quicker to movement of the car/steering/whatever. the tires respond to everything quicker than if the exact same tire at the exact same pressure is not stretched onto a wheel. I'm not saying thats better or worse, or if you should like it or not. you can decide that.
