stretched tyres

what size tyres looks best on a 15" 7 j rims giving it the best stretched look?

none they are dangerous.

At a guess, the answer you got from the last response was not the sort you was after so here you go mate

Good site here giving you pictures of all sorts of combinations of wheels and tyres fitted to give you a better idea of what you looking for. But it does all depend on how mad you want to go really.

165/45/15 or 165/45/15 will give u plenty of stretch nakangs do those sizes too.

I never break the speed limit im a good boy!

On a serios note though I appreciate people do like stretched tyres.

I personally feel that they are not safe, but thats just my opinion.

but then again lots of things arent safe…

I have strong faith in the original manufacturers (for example Volkswagen, wheel manufacturers, tyre manufacturers) and believe some of this hype regarding the fact they test tyres thoroughly, and also offer technical advice to tyre fitters (who are after all, fitters, not qualified engineers or scientists) recommending a small 'range' of tyre sizes for a given wheel size.

However I am not shy of a bit of 'modifying' cars. But you can modify a car for different reasons. Mine is for performance increase, measured in quantifiable things such as power/weight ratio, acceleration, etc you get the idea.

Its come across many times and despite a lot of discussion, I've not heard a clear argument FOR stretched tyres except for reasons of looks. For me, looks alone aren't really a strong enough justification to deviate away from the manufacturer's recommendations, etc.

But I'm quite open to listening to a concise explanation from someone in support of stretched tyres, who can also offer the technical/engineering/scientific insight as to why they're in fact okay and the tyre manufacturers have it wrong.

*sighs* this is always a topic on e38 lol

stretched tires (from memory) wer used on old jap drift cars an hot rods in the 50s.

on jap drift cars they would fit huge wheels out back and because ther wasnt a tyre big enough they would stretch then giving the wheel supposedly more contact to the tarmac. helping with traction to drift etc etc.

hot rods basically the same but not for drifting just for straight line speeds

however ive never seen or heard of a tyre with stretch coming off or being in any way unsafe. people do take it to the limits and run the risk of it coming off the wheel or the bead etc. you can post up pics of em coming off if you want but 9 times out of 10 it wasnt the tyre that gave way.

also stretched tyres are high maintainance as you have to run them at a higher psi.

people these days use them for asthetics or jus to help ther car go lower so the arch doesnt scrub away the tread.

I wouldn't personally put stretched tyres on any car I was using.  I don't see the point in getting wide wheels if you aren't going to use the extra width to get a wider tyre on the road (and therefore, more rubber in contact with the surface).

I also wouldn't fancy using tyres that have been destruction tested and type approved on a 5.5J wheel on, say for example, an 8J wheel.

If I had a set of 8J alloys, I'd probably run 195/205 tyres over 165's as they are, well, they are wider aren't they - which is surely the point? lol

you can argue all day as to why you wouldnt an that you think its stupid or dangerous but people will still do it.

will just go round in circles.

i answered the topic starters question so job done

..but it looks about as good as a mullett hair cut!

Each to there own, if he likes it and knows all the pitfalls then it's up to him if he wants them on. All that was asked was which tyre gives good stretch not do you think they look good streached

thanks guys for the sizes
i had stretched tyres on my works s1 wheels on the rx7 which was running 400 bhp never had a problem
but each to there own i say, ie so is smoked rear lights which is down the same points its just for looks yet makes it harder to see!

here here! There are a lot of things more "dangerous" than stretched tyres, millions of people driving with bald tyres, bulbs out, insufficiently cleared screens in poor weather confditions, those without licences and insurance…. need i go on.

At the end of the day its up to an individual what they wanna do, all a "concerned" individual can do is offer their opinion/advice on the issue NOT preach about it.

it really is beyond boring now those that instantly go "its dangerous" Duh do you think people can't form their own decisions/opinions??? at the end of the day if you wanna run stretched tyres you know the risks that may or may not be involved. 9 times out of 10 if a stretched tyre causes any damage its down to operator error (incorrect pressures etc) not the tyre or the rim.

now lets all just get along and play nice.

Kinda agree, except to say that wider tyres in themselves, don't lead to a greater contact area:

Pressure = Force/area

therefore

area = force/pressure

So, with the same force (of gravity, the weight of the car on each wheel) and the same pressure, the area is in fact the same. The other downside to wider tyres is that with more/less the same area, instead of becoming a square, it becomes a rectangle:



This is okay in dry weather but in wet weather, aquaplaning can occur at lower speeds because the 'length' of the rectangle (in the direction of travel) is shorter.

The main advantage of wider wheels is that tyre pressures can be lowered, to give greater surface area and therefore more (in the dry) grip. But this also leads to greater drag - hence my (on a different thread) argument that it makes no sense running wider wheels on the back, than front.

Off topic, but another important consideration is sidewall deflection when cornering forces are applied. As a general consideration for tyres, the larger the wheel (diameter) and lower the profile of tyre, the less tyre distortion occurs and the car's geometry varies less, at an equivalent range of side loads.

Pic didn't appear, but all the info is on http://www.carbibles.com/tyre_bible_pg2.html

i have less of a worry about side wall deflection and more of a worry about the direction of force applied to the beading from said delfection.
a tyre with it's side wall 180 degrees (approximatly) to the wheel rim will have a greater range of deflection before the beading looses it's fit and comes away from the rim. if that angle is increased by stretching the wall to say 210 degrees your already on the limit of what the bead can cope with.
heavy cornering results in rapid deflation and one very major accident.

I agree with paul on this. (which is rare) :mrgreen:

stretch is dead

spacers are are back  :mrgreen:

de ja vu!!!

if this one gets locked too, then i'll know i've been back in time.

stretch was all started by some skint geezer that needed new tyres and couldn't afford wide ones, see he brought what he could afford and thus this thread was made.

NOT REALLY, but it could have been. :mrgreen:

i think stretch tyres arre as much good as my response to this thread.

however i do enjoy looking at them on cars and guessing at how long it will be till they have an accident.

any pics.
