Not an E but a Benz with Style




He's grown. He'll make his own decisions. Whether you agree with them or not, they are ultimately his decisions. I can understand stating your opinion, but to keep pounding it in is too much.
Vic and those of you who are also on myMB will know what I mean when I say that people are much more open-minded to mods over there.
"Stretch and poke" may not be your style. It may or not be "safe", but it's been done for years over in Europe, so it's probably a lot safer than you think. Is it less practical to run a stretch setup on an AMG? Probably, but, again, that's his decision. He's happy with his set-up, so let it be.

We dont need to bring this to a lynch mob style of thread. The OP did post his pics so therefore he will face the scrutiny of the reviewers and that has to be expected. Just make sure its done with respect.
Ill argue all day the safety of an over stretched tire outside of the section width of a rim as being not safe or functional on a high performance car. The car does look pretty good standing still.

You guys have your "stretch and poke" style...I don't understand it...to me it's unsafe and not my style regardless...but to each their own...just don't blow a bead and cause an accident where someone else can get hurt.

as for your comment about his stretch and poke being unsafe.......please post a citation as to where you found that info. people have been stretching tires for a loooong time. Ive see much more aggressive stretches than that with no issues.
thanks

This is not a matter of "wow that's cool looking" or "I like that style" ...this is pure engineering basic protocol...plan and simple.

As for stretching - Sunir is spot on - it's basic engineering principles.
Here's from Dunlop - probably know more about tires than anyone here:
This is an excerpt from Dunlop Corporations recommendations for rim width:
"RIM WIDTH
Correct rim width ensures flex at the designed flex point in a tire sidewall for optimum tire performance.
If the rim is too wide, the flex point moves towards the rim area, causing heat buildup in the lower sidewall, which reduces tire life and could result in failure. Either too narrow or too wide of a rim can result in uneven tread/pavement contact pressure causing uneven wear and potentially reduced traction, or increased vulnerability to bead dis-lodgement. "
Wider rims may offer some performance advantages over narrow rims. A wider rim increases the distance between the beads, which results in a straighter sidewall, which stiffens it. This results in quicker steering response and higher cornering forces.
Negatively, the straightened sidewall transmits more road shock to the wheel and suspension, placing greater stress on chassis and suspension parts and delivering a harsher ride. The straighter sidewall exposes the rim, making the wheel more susceptible to damage.

Put those stretched puppies on a car on a road coarse, or on a long high speed sweeper and you risk unseating the bead.
Tires are designed for a specific rim width - all manufacturers specify a range of wheel widths for a particular tire. They know far more on this than we do - and once you do something outside their recommendations - you are decreasing performance and ultimately - risking the bead - which is truly a safety issue.
Anyone that has done "real" performance driving - wouldn't touch this stretching fad.

i said that but i didnt mean most extreme...just alot more extreme than daily driving. sry for the confusion.




Taking an on ramp sweeper at 75 or 80 MPH and pushing the adhesion limits of a tire, or driving the Tail of the Dragon or other curvy backroads can easily surpass the lateral G loads of a drift car. By definition, the drifter is breaking traction - and therefore NOT stressing the sidewall / bead of the tire - they are SPINNING THE WHEELS and simply not pulling the g's.
I would no more trust a stretched tire for my more spirited on-road driving than I would a tired that was underinflated by 20 pounds.
As someone said early on in the conversation - form should follow function.
....enough with my engineering mumbo jumbo - who knows I could just be some ignorant guy flipping burgers at McDonalds whilst saving money to get some oversized wheels and skinny rubber for my Nissan Silvia drift car...with 2 Jay-Z's in my engine
...whatwhat! Hova!
It's not uncommon for the "stretch and poke" crowd to have several sets of wheels all at different fitments.
