Stretched Tyres

[mitch33]

What is the go with stretched tyres. Is there any performance advantages, or is it to save money?

[Ronin 09]

copied from the Japanese who wanted to look different - just a whole lof of "me too"

if it actually functioned better the recommended fitments from manufacturers would reflect a 225 width tyre on a 10" rim.

all motorsport has tyres which fit the rim properly - eg. V8s, touring cars, F1 etc etc.

yeh, like he said, it's got no real practical purpose but to look cool

I guess on drift cars, the less tyre on the road (at the back) = the better, so stretched tyres = less on the road (because they bulge in the middle)

from a grip standpoint, your getting less tread on the road though

although on high speed corners it feels like there is less flex in the wall. i just got new tyres (un streatched) 225 and it is now apparant on corners that the tyre has a little bit more give in it. just my two cents.

it's all about maintaining a loss of traction. conventional tyre fitments grip up earlier than the radically stretched ones.

yeh retro, there will be alot less sidewall on stretched tyres, so less movement, but better to just go a lower profile and have the same size footprint on the road, like you've done now, than stretch the crap outta them and scrooge up your traction

also stretched tyres means you can have a wider rim under the car as it won't hit the guards as easily.

yeah its about sidewall flex, not very drift friendly.

theres a fun way to stretch too. it involves fire and propellant

Wheels are there to hold your tyres. What's the point of running a wider rim if you're not going to use that width to crowd more tyre onto? All that extra metal would be unsprung ballast.

Interestingly, porsche stretch their tyres from the factory, ie 265 tyres on 11in rims

a lot of rims don't come in skinny sizes, and cars like sprinters don't have much room under the guards

[lingeringsoul]

anyone know if 234/45/17 can be stretched onto the rear 8.5 inch wide rims?

[SLI-Line]

yes, thats fine. I have 225 on a 9 inch. the reason iv done this was to eliminate any rolling of the tire wall. well, that reason and also because i cant fit any wider than a 225 under my guards.

the reason why i stretch my tyres on is to have a wider rim fit on the car with out your guards cutting up your rubber. and it looks phat as!

[gt-t_r34]

they say a small amount of scretch can make low performance tyres feel like a more costly tyre, i guess its marginal.. but some people go over board looks tough on some cars though....

[scathing]

Yeah, shouldn't be an issue.

I've stretched a set of RT215s in that dimension onto a 9.5" wide rim, and even with the amount of abuse I've put the car through I haven't had any problems.

[xRHETTx]

I have 235/45/17 on 9 inch wide rims. Reason - they came that way. And when i replaced the tyres i was scared that any wider would rub.

So you will be fine, i've driven over 100,000km in my r32 with these sized tyres. Its the extreme streching you have to be wary of.

[sh@un]

235 on a 9' is the factory fitment for 33 GT-R's

[06tst]

i run 235's on my 19x9.5" rims... purely for looks. i use 17x9's with 255 all round for track duites so im not fussed about performance when using stretched tyres on the street

[zaffa]

Its all about side wall flex and eliminating it. With stretched tires there will be less if any side wall flex which makes the car more predictable and easy to control when drifting.

Also an easy way to fit bigger wheels inside your guards instead on flaring or scrubbing!
