Also on my M3 the rears are 9.5 inch but the tyre is 255/35/19 from the factory! Basically BMW send them out with a slight stretch! Looking on a few sites a lot of people are changing to 275 rears as that's the size suggested for that diameter of rim from tyre producers.
So where is the line drawn in this argument?
I'm tempted to try the 255 on the front as it supposed to help no end with the understeer.
How is a 10" tyre on a 9.5" rim a 'stretch'? That's a perfectly normal tyre fitment, as would the slighly wider 275 section be.So where is the line drawn in this argument?

Sorry my mistake then! Was clutching at straws trying to prove a point about anything and nothing.

This is the European Organisation tasked with the resposibility of testing the various combinations of all vehicles that use rubber tyres.
They work in conjunction with other similar organisations throughout the world and are charged with making recommendations with regards to safety and suitability of the wheel/tyre combinations.
Their literature makes for interesting reading and in a nutshell it says that straying from the recommended tyre fitments removes the safety factor derived from extensive testing and to do so knowingly would leave the user of the vehicel open to various forms of legal prosecution and not only in the public arena but racing as well.
Food for thought.

There was an utter spunkmonkey cockweasel at the German marques breaky club last Sunday, with an RS2, on Porsche rims, with a massive tyre stretch going on. I can't imagine that any insurance company would cover that modification, and that said arsefiddling knobmonkey would be in a world of s
t, in the event of even a minor shunt. I hope there are enough insults in my post to gain at least one smiley in any replies BTW.

Every time I see a slammed VW with the driver appearing to be sitting on the floor I burst out laughing I really do....
How they get insured with their combination of age/postcode and dangerous mods is beyond me.
