yeah i can see where your coming from matey

...i love tyre stretch and can see both points of view.
it originally was introduced on jap cars, as its easier to drift on them or something, then the euro scene made it bigger and has become like a MUST in the dub and euro scene.
The loop hole in what your saying is, racing slicks have a law that theyre not aloud for road use...theyres a law in force saying you cant do it.
But with stretched tyres its only a reccomendation so its not technically something you have to 100% aboid by. the only law is that they tread has to be in the arches...hence why most cars running silly stretch have silly camber so its classed 'Legal'
