well i was readin around and started reading up on stretching a tire to fit a bigger rim. its said that it has more of a feel to it rather than the overlap or roll effect of the regular tires (not the low profile sports type). i was just wondering if anyone knew what sizes i could use on my 15s ? oh and im also wondering if my LSD could NOT be working anymore? because i peeled out on it awhile ago and it just left one skid mark on the street? i have an 86 gxl. i thought it had a clutch type lsd? if it is. how do i rebuild it. or replace it? does anyone know if its a 1 way, 1.5 way, or a 2 way lsd? thanks on any input.

Stretching the tire has generally been proven to be a bad idea unless it is under special circumstances. When you say use on your 15's I suppose you are talking about the stock 15" wheels on your 7? Stretching has to do with the wheel width which is probalby 6.5". To get a tire narrow enough to "stretch" to fit a 6.5" wheel you are looking at putting a 185 or smaller tire on it. You are going to loose more performance with contact patch than you will pickup with the false stiff sidewall. It would be much better to buy the correct width tire in a low profile design.

I think stretching the tires are only beneficial on odd wheel sizes where the only available tires are tall and roll over too much. I have seen it successufly pulled off on heavy highly modified cars that run huge tires (15" x 15" and bigger). One in particualr was a mid 70's Z that had a Corvette motor in it. The owner had loads of money tiedup in it and was nothing but business on track. He had a widebody kit on it to cover the excessive sized wheels. And if I remember the numbers correctly he run a 12" wide slick on a 15" wide wheel so he could still run the tall tire he needed/wanted and get a really stiff sidwall. And it may only be actually work when using bias-ply tires (as race tires would be) instead of radial tires.

I can't help you with your LDS questions...

Oh no!
Not on here too!
I expect this on drifting.com...but on here???

Stretching tires is a horrible idea. The only people that do it are the low riders, and I still can't figure out why. It look ridiculous, hurts performance, and is dangerous.

For a 6 1/2 inch rim, I would recommend a 195 to 205 width.

reza

how about 225/50/16 on a 16x9"? or 245/45/16 on a 9.5" or 10" Are these considered stretching?

86gxl_fc

its supposably the cheaper way of have low profile tires. i dont know if its a danger, probably is if certain circumstance were to come to play, but mostly the reason i was thinking of doing this is because i dont have any money to buy low profiles right now, so a quick way to do it was to go to a junkyard or tire place and get some old tires and get them to stretch it on. less play than the original 15 tires because theres less shoulder room on the tire, so kind of makes it stiffer.

I think we stretch tires simply for one reason, PHAT LIPPAGE. haha. Too much stretch is dangerous. I know people who's tires have just lost air on the freeway. But we're talking 18" wheels and 35 series tires etc....

Oh and 86gxl your thinking can actually get you into some problems. I wouldn't go buying used hardened tires for daily purpose. Simply to burn the **** out of for drifiting. For a small insight to your dilema.

Your wheel is too thin to stretch a tire on. You need to get a 8.0" wide wheel at least to get a decent stretch in that wheel diameter. So that isn't even going to happen don't even bother. You have to buy new wheels to accomplish that.

Secondly, are you looking to get a shorter overall tire diameter, in turn changing your gearing?? If that's the case you can do that with like Miata size tires or civics etc.... If you want to do that make sure you have a good reason.

Lastly, just let us know what you're trying to do with this car. What are you trying to acheive? Are you drifting? Are you just looking for a set of spare wheels and tires to toss on for tearing up?? Or are these tires you will daily drive on etc....

For your LSD, I don't think you can rebuild the stock one. I'm not sure if you can get a rebuild kit. Time to get a KAAZ, ATS, Cusco, etc....

If you are still NA I can recommend a few other places you can obtain drift easier with the FC. Just realize that the FC is a not so good drift car. It can be done but is more difficult.

Reza,

Each rim size has an optimal tire that corresponds. For example, lets say that an 8 X 16 rim has an optimal tire size of 225/50/15. You can probably be safe with a 205/55/16 up to a 245/45/16. While safe, those tires are not on an optimal size rim.

I think you are generally OK if you are within 1" from what would be optimal. A 245/45 would be best suited for a 9" rim, so a 9 1/2 or 10 would still be OK........ according to "Adam's rule of thumb"

i was just curious whats the smallest size thats somewhat considered safe (even tho putting smaller size tires isnt really considered safe). the reason is because im just goin to swap out my daily drive tires with these just to tear them up, im thinkin about switching to the KAAZ lsd in a couple of months (savin up money). thanks on the input Anotheraznguy, i get what your saying totally, but thats kind of the reason i got an fc, i like rotary style engine, and the 50/50 weight setup shouldnt make it that hard. the only thing i could think of is the trailing arm that could give me a problem, oh and the lack of power, but still i like challenges nevertheless. thanks on the info guys.

The hipari is only great for shows or drifting. I wouldn't ride on them for the daily stuff. But for drifting it does have practice reasons, like getting rid of body roll and also it help cut down on the traction. Go with a 200 front and a 180-90 rear pick a tire with strong side walls and really round shoulders. But forget all the ney sayers cause there is great reasons for running the hipari style.

As far as your diff is concerned its an lsd (limited slip diff) its supposed to apply the power to where its not getting traction.

it depends how far you want to stretch it. there's a safely allocated amount. for track i'm running 255 on a 17x10. lots of people run this setup and have no problem with it. when you run a tire thats too stretched, be careful if the tires pop the bead

alot of guys on here drift with welded diffs and stretched tires. you save money and no huge hp numbers required. its also mad tyte jdm and you can tell ppl you have a 3 way lsd
