First thing is there is a few cars that are stock 200mph ready, like I said the Y-Rated tires are NOT RATED FOR 200MPH. They are actually rated for 186MPH. There is (Y)-Rated tires that have been rated for 186+mph, and, not even AMG ship with those as OE, you have to go after market and buy them.
And to say 200mph is safe is just stupid and dumb. You have to take in to consideration PSI in the tire, as the heat its going to generate and could cause your pressure to spike.
There might be a bunch of video on youtube but it does not mean people do it every day and its normal and safe. If i wanted to make a 200mph, yeah its do able if i get my car prep'ed but on streets roads in the US, no thanks.
I dont know what tyres the SL65 comes with, but the fact that they can do 200+mph everyday, 365days a year proves that the tyres are capable of doing that kind of speed.
There is nothing seperating from a Ferrari 599 and a M5 hitting 200mph, they both use the road tyres. So accorind to your theory, it must be fucking dangerous to be in an 200mph 599.
If it was dangerous to do 200mph in those tyres (regardless what rate they come in, could be Y or better), BMW/Mercedes/Audi would never take off the limiter for the customer. They must be fucking mental in the head to remove the limiter for the customer if its as dangerous as you say. If the tyres cant handle those kind of speed, dealers will NEVER EVER remove limiter for customers, knowing that they will get sued to bankrupt if some shit happens. And lets not mention all the endless testing and wind tunnel to make the car safe and drivable @ 200mph+ They are called super saloons for a very good reason, to say 200mph is dangerous in an M5/M6/E63 etc is just fucking stupid.
200+ is only dangerous if you are doing it in an modified car, since there are too many unknown variables that could go wrong, but factory stock cars that are capable of cracking 200mph is a totally different story, they've been tested countless of times before it even goes into production. If a bone stock car, straight from the showroom floor, can hit 200mph, then it is completely safe to do so.
so piss off with the comment like
beacuse it is that safe.And to say 200mph is safe is just stupid and dumb.

this is just some random video of some random oke from a random place doing 200+ in his M5, so what were you saying again???
i know okes that do 200mph+ every sunday morning for their breakfast run, and so far i havnt seen anyone pegged yet.
Tyre pressure my arse, even with an over inflated tyre, 200mph is still achievable, unless you have the tyres pumped up at a riduclous pressure (3.2 bar for example), going flat out is not going to kill you. So let the big boys do the 155mph+ talk, cos it seems like you havnt gone faster than that. Ive driven plenty of Mercs that runs on spare tyres with the wrong tyre pressure, and at no point was i reluctant to put foot and watch the needle climb to the end of gauge. I agree tyre pressure is extremely important to a car, but it does not make the ride dangerous, unless you deliberately over inflate them to a point that you know you shouldnt be doing. Besides, all the correct tyre pressure are allocated on the side of the door panel, back of the fuel cap, and in the owner's manual. It is very hard to go wrong unless you dont know how to read numbers.You have to take in to consideration PSI in the tire,
Tbe M5 and M6 both handle 200+ fine, if they were not designed to go the fast the gearing would not allow them to go that high and they would be have all the features to make the car steady at that speed
