View Full Version : Stretched Tyres

Hi everyone

I'm thinking about buying a set of wheels with tyres currently for sale but im a bit worried about how stretched the tyres are. A google search shows a lot of mixed opinions on heaps of forums and even dedicated websites give both a mix of opinions.

That said, no one really gives a rule of thumb of how much stretch is too much

The Wheels im thinking about buying are 9.5x17 but only have a
215 / (unsure of the measurment for aspect ratio) / 17 tyre

The aspect ratio is probably really important when it comes to determining if this is a big stretch but what i want to know is if fitting 215mm tyres on 237mm wide wheels is as silly as i think it is. If its safe, what Aspect ratio should the tyres be for problem free driving

I dont intend to track my car with these wheels however i would use them for daily driving and the wet skid pan at eastern creek when i get a chance.

I'd appreciate if people who run stretched tyres give a bit of info on what tyre they use for a certain type of wheel and if they have ever had any problems like google images says you will have if u run stretched tyres

Sorry in advance if there is already a thread on this, used the search bar but couldnt find one.

215 tyres isn't always 215mm wide. Most tyres' tread width are slightly narrower than the number indicates. The only way to find out is check with the manufacturer's chart, or measure it physically.

There is no secret number or calculations of what is best stretch fitment to use.. Just know if its stretched the tyres are not working at its best as designed. We are talking about stupidly crazy Internet stretched tyres. A little stretch is fair but a lot is just plain stupid.

265 it's the natural width for 9.5".
it's a fair bit of a stretch.
this would be used in a car that wanted the hella flush stance

A 215 on a 9.5 is way over stretched, as an example I have a 275 on a 9 inch rim and its only slightly bulgy. Min I would run on a 9.5 would be 245, even then I don't think that's legal.

I run a 215 45 on a 17x9 on the front of a track only drift car and it's not very stretched. I've run a 215/40 on a 17x9 and it was way more stretched, point being that 40 and 45 is a pretty big difference for the same 215 width!

My biggest concern with the 215 40 was that it was pretty much a rubber band the profile was so thin, you really felt it when you hit pot holes/ripples/cats. I wouldn't run a 215 40 on a 9.5 by choice if you are going to be super upset if you put a little bend in the lip. But a 215 45 would be more than OK for street and drift depending on the tyre model.

A couple of the guys I skid with have de beaded 215 40's and 35's off 9 in rims when we are at the track. Its why i dont like streatching on the front (235 on a 9in rim is as far as i'd go for steerers)

But if you get the right offset you can fit 255's under the front of most nissans. I dont know why you would want less grip at the front.

It completely depends on your driving preference. Some drifters prefer a slight understeer bias, I know I do :)

True.Not saying one is wrong and one is right. each to their own. I like a tight front end.
But that comes from the years of circuit racing prior to skids.
I just feel more comfortable with it.

Yeah it definitely feels more reassuring, I just find that if you don't over-grip the front you can really throw the car on entry and get it to snap into a 4 wheel slide quicker. With heaps of front grip I kind of feel like the car is just doing a controlled burnout with the front end totally planted the whole time? It's hard to explain, and I'm off topic :) hahaha. Just wanted to answer your question why someone might want less front end grip. Most of the time I run a 225 front and 265 rear on the 180. 215 front and 235 rear on the FC.

Humm. I will have to give it another go. At the moment I am on 245's all around.

Thanks for the insight.

Did they debead when skidding in the dry or wet? or were they simply just driving along when it happened?

yeh i went to the skidpan with my s14 which had 235's on the front and 245's on the rear and i swapped with my mate one run who had 215's all round. I know exactly what your talking about in terms of entry.

De bead In the dry.
Normally involved a big entry or ripple strip. But I have had some massive fuck ups including accidental air time and never de beaded a tyre.

Lol. My skyline did the same when I was running some fat semis for a while. All good. Would do it again.

I'd say 215 on a 9.5 is pushing the limits. I run 225/45R17s on my 17x9.75 wheels and they offer a lot of stretch but are pretty safe in terms of debeading etc. (I've never had a problem). 235/45s are also a good size on 9.5s. As best guy said you run the risk with a 215 of smashing a lip, compared to a wider tyre having less stretch and therefore more sidewall flex to absorb bumps. In the end there isn't really any hard facts on what will and won't work, all you can do is go off other peoples experiences and decide if that's the look you want and whether its worth it.

Another factor is which brand the actual tyres are, as stated on the last page different manufacturers = different witdths/sidewall designs and that affects the sidewall and how strong it will be.

i got 225/40/18 on a 10" and it leaks air around the bead like a bitch.

might have more to do with the rim if the tyres are new... Had heaps of 225/40/18 on 18x10 without issue

^ so what Brand/model tyres are you guys running?

I have to admit, Stretching 215/45 on a 10" rim sounds ridiculous but if your not de beading/leaking air then you probably have the right ruber compared to Peggy

lol wtf

right rubber? stronger side walls?

stretching tyres just got serious..

make sure your Rotas are not buckled
buy brand new cheap ($80 a pop) tyres with profile no smaller then 45 to lower chances of it losing air or coming off the bead if your so worried about safety because safety always comes first right? not wanting your tyres to fall off your rims while driving now would we

stretching tyres is stretching the sidewalls (because you fail to buy correct width size the sidewall now has to flex and cover the extra distance)
Lower profile means less flex and less area they can cover, a 40 profile will have shit all stretch flexibility compare to 45 or 50 profile..

get semi slicks or full slick tyres, they got best rubber and sidewall, should have NO issues when stretched

Yeah I think it may be the tyre itself as the tyre is a bit old. Was sitting on some stock wheels before I switched them over.

Nice car man. I got a Gen 1 Accord. Has 13" Honda Wheels but I havent tried stretching anything yet.

I got a set of original "Simmons" which are 15 or 16" i cant remember. Once i get those I will stretch some rubber on those bad boys LOL

LOL I know a guy who bought I think it was like 16x8 with 0 Offset for an EK.

Major Major FAIL. Stuck out like 2 inches from the guard.

Got his mate to roll the guard and guess what.. still didnt fit.. even with the Coilovers angled all the way in and his mate flaked the paint on all 4 guards LOL

Nice :D Should look good

As for above; I'm going 13x7's on the car I posted, hah. Probably +0~ offset... but bolt ons, so can sort of justify that

Haven't had any issues yet.

On my old JZX100, I had 215/35/18 on a 9.5" rear and my mrs at the time was driving the car and it de-beaded off the rim whilst she was driving.
