Tire strech

[Mr Revhead]

in this thread
ppl have said stretched is good and safe and better for performance

redmist is merely correcting the inaccuracies

others have pointed out the legalitys. or rather the lack of.

[postfach]

Redmist, Snoozin never mentioned "rally, road race, touring car, offroad race, blah blah"

to be fair he only mentioned them on drift cars, which isn't classed as "racing" is it?

Did you read what Redmist wrote?? He was responding to Snoozin's comment on lateral load (which was incorrect), and how while drifting, there is very little, hence why drifters don't often run into problems with using an incorrect tire/rim combination.

He then went on to point out (in a roundabout way) that people who are more interested in performance, over looks or style, use a correct combination of tire and rim size, because stretching tires is actually detrimental.

Way off topic now, though.

I don't care whether its legal/illegal or good for performance or not tbh, I am yet to see any hard evidence that it's unsafe....

Not unsafe + looks sweet = mean.

It's not a drift thing either, the Euro boys and the bosozoku/garuchan folks started doing it in the 80's before todays baggy pants wearing filthy hoodie ridden backwards cap toting gaggle of followers had even heard the word drift....

and i hate it when people instantly remark about "oh drift spec stretch au" not knowing it was started way before drifting. i know its been adopted by the drifters and there the main people that do it but it still gets to me,

if people want to hate then hate the VW, fiat, etc, euro guys for starting the whole "fad" wow a fad thats going on 30 years...is that still considered a fad?

oh in all this hype i forgot to ask, whats the car these wheels are going on? because your thing says subie racer and itr, if there going on any of those two then there gona look really ,

Practice > theory.

Never seen a drifter have any troubles with them, and they run some fairly excessive stretch and one would think some pretty extreme lateral loads on their sidewalls.

Actually I think you would be amazed at how little lateral load they have on a spinning tyre. It's probably in the realms of a tenth of the lateral G's exerted on a Formula 1 "balloon" tyre. If stretching performs so much better than a correctly fitted tyre then why arent they fitted to proper race cars? I've never seen tyre stretch on a rally, road race, touring car, offroad race, formula, sprint... even dirty roundy rounders.
I'm not here to debate, I just dont think you should promote tyre stretch as a performance enhancement as it is clearly not. At best you're increasing inertia (by having too much rim weight) and loosing a bit of traciton, at worst you are creating an explosive and possibly catestrophic situation..... all for a look..... which I personally "limp pinky" at.

heaps of race cars run moderate strech... i jst did a 1min look around and found these two pics that you can see the strech.

[Mr Revhead]

ok.....

your not serious are you?

on my ae85, or 180sx..... dont care what you guys think, i was only asking what the minium size tires i could strech on my rims.

What you see there is side wall flex in action (due to cornering), look at the top of the tyre - looks normal doesn't it?

Shhhh don't mention sidewall flex, race cars arent supposed to have that, its a bad thing remember. Does something stupid like keep the tyre in contact with the road, DUH.

Both the cars are running the new type of stretchie, the just stretch the bottom of the tyre on the outside corner wheelset. Makes them look way cool. Bitch for the pitcrew though who have to change wheelsets between left and right corners. Oval tracks are considerably quicker for obvious reasons.

I guess I'm too old, too cheap, and far too analytical for modern "car entheusists". Dont know why but I always tend to spend my performance enhancing dollars on something that ... ummm... enhances performance?

...or at least I try to.

NEWSFLASH: Some people like doing stuff to their car for the look, not necessarily to make it go faster, handle better, stop quicker. Deal with it.
