Still have yet to see anything to back this up.
I'm not into the whole stretch thing myself, I prefer a flatter sidewall, but I just don't like how it's being restricted without any real justification.
Show me some stats where stretched tyres caused more accidents then, well, anything at all really, and I may change my opinion of this ridiculous law.
But it this stage it just seems completely stupid.
Cut / dodgy lowered suspension, yeah. Unsafe. Makes perfect sense that shit like that needs certs, I can think of a few cases off the top of my head where some moron killed himself coz his springs raped his tyres.
But every man and his dog goes on about how unsafe stretched tyres are, but yet have never seen a documented case where it has caused an accident.
Anyway, cig time. That's still legal, right?
