The Official "Stretching Tyres is for Idiots Who Don't Drive" thread

I know a ton of you haters on here were making fun of stretched tyres. A lot of you said stuff like "Its just for looks", and "It's dangerous; not within the recommended manufacturer specs."



SO I give you you guys a present, validating your thoughts, and reinforcing your fail-safe il-logic.

This is me, first time out on the track in the RX7. 17x9.5 +2 in the front with 235/40/17. 18x10.5 +0 in the rear with 245/40/18.













If my tyres did not rip off the rims doing **** like this, how the **** are you guys going to tell me it is still unsafe and hazardous to run streched tyres. Under normal driving conditions, too!!!


Hate on it all you want b/c you can't understand it, but i must be doing something right, if anyone cares to expand their thinking.

The thinking is that if you merely wish to run a 245 you don't need a 10.5" wide wheel to do so.

I notice in one picture your car has a front end and in another the front end is gone?

Is this you too?

I'm just trying to figure out if the rear tires are smoking from actually sliding or because they're rubbing against the bodywork....

You must be doing something right??? What kind of tires are you running? There is absolutely no give or flex in a tire that is stretched on the rim, therefor making them easier to break loose especially when you're running skinny tires like that. I'm not saying its dangerous, I'm just saying its a waste of rim, and grip. But thats not what you were going for now was it, it was more like super JDM Drifter Style.

Haha yup that't me testing out the rock crawling abilities! Like I said, it was my first time in the RX7, and it's not as easy to drive as my S13 was. But DAMN it was a lot of fun. Made me work, and adapt my mindset to cope with the 7s low polar moments, and more central pivot axis compared to a 240.



At the end of the day I placed in the top 8 (it was a competition... i know... first time in a 7 and its a competition, SMART). Going from 40 to top 16, I was qualified 1st. 16 to 8, I was 2nd. I'm quite happy, but I know once I'm more comfortable in the car it'll be a bit easier.



And yeah as you can tell by that pic, i didn't put the aero on till later in the day b/c I knew it'd take a bit of time to get the hang of the car.

Yeah.. "must be doing something right" b/c of everyone that says stretching tyres has no function. I don't want my sidewall to be squishy and flex. I want it to be stiff and consistant.


Super JDM Tight drifter style???? Get real. I could care less about "JDM" trend ****. I did something that ******* works, and actually drive the **** out of my car. How is that still "following a trend" or any other bullshit?



Was running Federal SS595s. The tyre is super grippy compared to most, and it copes with heat really well, making it less succeptible to delamination. Treadwear isn't terrific, but its a lot better of a tyre for drifting that you'd think.

Hey, it's the "I've still got my head in the sand" thread.

A. Nobody said your tires will fall off the rim. You made up that position, so that you could tear it down.

B. It looks like your front wheel totally lunched on your fender in the 2nd photo. Probably because, though a very low offset will fit with the wheels straight, you've placed the center of the wheel much further out from the rotating center of the spindle, so the scrub radius is much more positive, and thus more likely to hit the fenders when turned. That's why with front wheels, you shouldn't run a lower offset than you need.... a more positive scrub radius means the wheel will "swing" more as you turn it, rather than rotating around he spindle.

C. The bottom line is, you wanted to run a 235/245 combo, which you could've accomplished with a 9.5" wheels all around at the UPPER END of the manufacturer's range. You didn't need 10.5's. Let alone +0's. You probably didn't even need the wide fenders if you weren't running +2's up front. You could've put those tires on the widest rims recommended for them which would've been PLENTY, and got them in offsets that would **** up the suspension geometry, and would require wrde fenders, and wouldn't **** up said wide fenders. In fact, if you want the rear to slide around, you might actually want to tuck the rear wheels IN for a narrower track.

D. On the whole "I need it this way for drifting" rationale, before drifting even became a term, a friend showed me a video of some guy running the entire Nurburgring old circuit on a Porsche 911, drifting every corner. Regular old wheels and tires on. He seemed to do fine without jacking his car all up.

Acutally the fenders were broken by a friend of mine who's car it used to be. They are re-glassed from underneath and they did not break at all with the 9.5 +2s. Rubbed a little, but no breaking.



Ughhhhh. If you add a lot of steering angle to FCs (SuperNow steering angle kit) you start encountering problems with having so much angle at full lock the inside of the rim actually hits the front sway bar. To prevent this, you need to run a lower offset. I'll take a slightly increased scrub radius over that any day.



If you guys are going to say I made up arguments jsut to shoot them down, then why not explain to me WHY I can't be running these tyres on these rim sizes? So far i've really only heard "It looks dumb to me." and "Its a waste." WTF. Could you be more vague?


I guess my main argument is that while not everyone drifts, or sets up a car like this to drift, certain things are done for functional reasons not encountered by those of you who don't build a drift car. Next time you guys want to criticise the way something looks, i want you to consider that perhaps there is a REASON behind it, not just done for looks. Sure, some things ARE done for looks (do you really need a bodykit?) but shiiit, MOST of the time, there is a function to things.

Build a drift car? Looks like you took a perfectly good car and tore it down into the kind of busted *** "drift" can that I spank at autocrosses regardless of number these functional mods you fools put on.
My favorite drift mods:
Cowel induction hood using washers as spacers
Mismatched wheels that don't fit
low budget tires as mismatched as the wheels
Zip tied on body components

Oh jesus. Tell me where you see any cowl induction fairy-land bullshit on my car? That **** is lame and it doesn't work for dick. **** raising the rear of your hood. high pressure area=air going INTO the engine bay, not coming out.


Yes, BUILD a drift car. Custom coilovers, steering angle, full cage, stripped chassis, Painless wiring, V mount FMIC and radiator, ATS carbon 2-way LSD, custom exhaust, blah blah blah. Your car could beat me at Auto-X? i'll never know, nor do I care. I'll go ahead and say probably. Give you teh benefit of the doubt. But that doesn't mean ****, you have a car setup for auto-X. How would it do drifting? Apples and Oranges, mate. If you want to beat the **** out of me, lets stop pretending cars are fast and race some 125cc shifters. then you can show me you're a better driver, not a better Auto-X car builder.


Next, how is running different wheels a counter-productive thing? I own 8 wheels, 4 match, the other 4 are spares and they are all roughly the same size, jesus christ, I can't afford to buy the world, i still pay for tyres and entrance fees and gas (******* 110 octane), and the list goes on. Don't give me that ****. I'm not running some ******* 16x6.5 steelies in the back!

Wheels that don't fit? You guys are ******* haters man. Haha. Wheels that don't fit are those lame *** 19s on an FD a couple threads below this one.

Low budget tyres... I love this one. If you don't drift, you have no idea what works and what doesn't. Yeah, i can't afford to drift on Advan AD07s all the time (done it before) but I've had a chance to drift on most tyres out on the market. Some work better that others handling the high temperatures you get while drifting. While they may not be the most expensive tyres all the time, they can cope with the track temps better than a lot of higher priced tyres. Such as Michelins, Bridgestones, Yokohama AVS (and ES110), etc. Because of their tread design and compound, a lot of higher end tyres are prone to total de lamination, ripping the tread off of the steel braids. Same goes for the shitty low end cheapy tyres. Cooper, Nankang, Hankook (RS-2s work pretty well for front, not rear), Some Dunlops, etc.

And how is running the same brand and tyre compound albeit different sizes being mismatched?

Ziptied on body components... Go build a show car and park it on some carpet if you don't like zipties.

I'm not gloating about running some $1,000/gal gas, I'm saying I put a lot of time and money (all I have) into my car and competiting in this series. Why? b/c you guys make fun of "cheap" tyres and zipties. You can understand that if I have to run 110 in the car, pay for everything and put time into building and maintaining a car, its certainly not a cheap situation. If I could afford to run AD07s all around everytime, i would! No questions asked.

Have you guys ran drift cars at Auto-X? They suck. Understeer city. Its a completely different world. Track drift cars usually will have too stiff a suspension, too laggy of a turbo, and too agressive of a diff to turn good times. But I dunno, grip driving mountains or tracks is pretty fast/fun in my car, since its a bit more open and higher speed than Auto-X, ya know. If I wanted to do Auto-X (and could fit in one) I would set up a sweet Miata.


Or one day, Lotus Elise/Exige... with a 300hp turbo K20, clutch LSD, and R-compunds. That would just rule at doing everything non-drift related.

Dorito, IMO, you should do what you want with and to your car and be happy. But how can you not expect to take a beating when you start a thread like this? For God's sake, man, look at the title!

No one will ever be able to convince me that putting rediculously undersized tires on rediculously oversized wheels is a good idea, has any performance advantage or looks good.

It looks rediculous to me.

It's a waste of money to buy huge and expensive wheels then put small tires on them that'd fit much better on properly sized, smaller, cheaper wheels. Drifting is a crash waiting to happen, it'll hurt that much more when you bend a wheel that size. The tires will offer ZERO protection to the wheels.

It causes a lot more fittment problems than running those tires on properly sized wheels.

They extra large wheels are heavier, with more mass out at the edges wich causes slower acceleration and worse handling from the increases in moment of interia and unsprung weight respectively.

The supposed advantages of better feel and turn in are rediculous, you can get good feel and turn in with any short sidewall tire as long as it's reccomended wheel or up to the max reccomended width.

It's not reccomended by the tire manufacturers. They know a LOT more about wheels and tires than anyone doing this does.

Finally, just because you can do something doesn't mean you should. Sure it might "work" but it's FAR from ideal.

he said the bumper was off in the first session(s) because he knew he would need time to get used to the FC. sounds like he knows what he's doing.

I agree stretched tires look silly, but at some point these drift guys have a proven setup with the stretched phenomenon.... I think it must add to the predictability or consistence of the tire performance and provide some slip angle to help the car slide gently in and out of grip to make the entire motion more fluid and easier for them to control.

they arent trying to get the fatsest time around a course like an SCCA spec Miata would.

I think BoostinMyS5 has a pretty well setup drift FC and seeing his setup of 17x9.5 with something like a 215 tire stretched on it with a 235 out back on a 10.5, seems like an optimal setup for what the car is being used for.

yes I think its goofy for a streetcar to run stretched tires for the look, but hey its their car let them do what they want.

I'm all for grip, but when I look into some supercars tire setups, I commonly see a setup of a tire on the maximum width wheel that the mfg'er recommends... like a 255 tire on a 10" wheel... I think thats on the Noble MR400 maybe? Drift guys that know what they are doing have just taken this stretch one step further and for good reason... slip angle and stiffening the sidewalls, even more important if youre burning thru cheap tires when you cant afford super nice made-for-drifting tires, those arent cheap!

and who doesnt love a rear-end-wagging, tire smoking FC picture?

Its like trying to get my grandfather into hip hop or sushi...he likes his IHOP tbone steak.
BTW congrats on beating the **** out of your car and not just straight line racing it.

It's not that I'm hard headed. I'd just rather have tires that fit so that I have more rubber on the road, or smaller, lighter, cheaper wheels.

The reasons for doing the stretch aren't that good. Turn in, feel and stability? Come on, all of the supposed benefits can be acheived using a wheel size reccomended by the tire manufacturer. I do agree that it's better to be on the wide end of the reccomended widths, but the stretches being used are just rediculous. If I had 10.5" wheels I'd want something like a 285 for more grip.

Ted, i know you are a very knowledgable guy. Its apparent, and I'm sure i've used some of your helpful information at some point in time, but seriously, c'mon. you're saying don't do something b/c later on in life you'll look back and say "oh man.. i was young and reckless." Sorry grandpa, I don't mean to be rude, but you never did something in your 20s just to live life to the fullest?

The other day I went skydiving for the first time. I wanted to get a rush/feeling of adrenaline, etc whatever. Don't get me wrong, that **** was FUN, but I dunno, comparing it to racing and drifting, it wasn't as exciting as i hoped for, you know?

You guys would probably say "Why jump out of a perfectly good plane?"
-To have fun.

"Why run stretched tyres and big wheels, bodykits, and slide your cars around a track when you could be running big tyres, save weight, or driving in a straight path??"
-To have fun.


Stretched tyres are MUCH more responsive and predictable that "proper" road sizes. If you disagree, I just urge you to try it. I'm serious, i think we could organize something like that. A control (the car and driver) and the variables (235/245 on a 9.5/10.5 vs. 8/9). Would that put an end to the functionality argument?

and thats fine...keep on driving with your 285 rubber and grip drive. Thats what you like to do nothing wrong with that. As far as stretching tires...have you ever driven on them? I think its safe to say no you have not. The benefits are huge especially the predicatability once the tires loose traction.
