stretched tyres

Looks crap and is dangerous as you are running tyres way out of manufacturer tolerances. People doing this are asking for trouble.
 
Its a FACT that doing this is running tyres out of tolerance, they are not designed for this. As such it must be dangerous otherwise they would be made like that. Add this to the statistical facts about chavs and accidents, and you have a quite plausable link.
 
Because when a tyre manufacture makes a size of tyre, they put a recommended wheel rim width this tyre can be fitted on, if it was safe to fit stretch a smaller tyre over a wider rim it would have been included and classified in the tyres sale specifications, it isn't for a reason.

When you go round a corner fast the sidewall bends over and the tyre bead tryes to break away from the rim, forcing the sidewall and thus bead to be angled differently could result in the bea poping out easier.
 
All tyres are made to a spec, this is a manufacturing tolerance and is there for the end user to adhere to, insurance companies, MOT tests etc also look at them.

They cover rim size, width, speed, tread depth and others.
 
I like a mild to medium stretch tbh. Not keen when it looks like the tyre is about to peel off the rim or the rim looks massively 'exposed', like the fiesta earlier in the thread.

That simply doesn't happen though.

I'd be interested to see this.
 
Tolerances are always there. However, good quality tyres are much more likely to survive these extremes than Linglongs.

I remember reading a German article (ADAC probably) where they tested tyres to see at what speed they burst, running deflated, etc.

The cheap Chinese tyres exploded very very easiler.
eg. doing 110mph on tyres rated to 100 for example. Contis, etc would last up to 120+
 
Chavs don't stretch rubber, most of them can't afford it. They buy linglongs for their crappy halfords alloys.

It's strictly a dubbers thing really, a marmite mod, like modified steelies. Some people don't understand it.

:cool:
 
If they are so dangerous why do the majority of people who drift their cars use stretched tyres? Surely if they are sliding around corners at 50/60mph they wouldn't want their tyres coming off..

I was told that a stretched tyre would stay on the wheel, the only problem is when they aren't running the correct PSI and then there's the SLIGHT chance they may come off.
 
The problem is the tyre load is not vertical, and the side walls can overheat due to excess flex.

On my Integra i'm running a 205 width tyre on a rim designed for 195 that causes the same problem. Some of these rims look like there mounting tyres 2-3 sizes narrower however, pronouncing the problem even more.
