you are right because at F1 when the driver is spinning in a corner, they have to put there foot down or add abit of gas and let the traction come in and let it do its job and try to fix it and come out of the corner

 

ya drive safe when wet you dont know what is going to happen on the roads unlike the tracks

 

Forget the Bridgestones on the E60 they ride far to firm. Any tyre / tire badly worn will have a tendancy to aquaplane / hydraplane on a wet surface. Also just because your driving in a straight line does not mean the car with electronic aids will not go into a spin particularly on roads with a camber. No road ever has a perfect surface so pockets of water will also affect the performance of the tire to remove water and can act as a drag on one wheel while not on another again aiding the spin.
Simple fact is any safety officer will tell you to slow down in heavy rainfall 75MPH is simply asking for trouble particularly on worn tires.
The Michelin tires are good wet weather tires but in most tests the continentals come out best.

 

Back to tires:

IMO the best tire to use in the wet is Goodyear F1 GS-D3. It is modeled after Formula 1 rain tires and it works great even in inch deep water at high speed. I have them on my Audi A6 3.0 Quattro and they are absolutely unbeatable in wet road conditions.

They feel a lot more confident on wet roads than the Bridgestone Potenza 050A's on my 530Xi.

Regardless of how good your tires are, once they are worn down at the shoulders ("the cords were showing" in your case), the water will have no place to go except out the front (plus a bittle bit out the back, depending on how deep your groves are) through the groves because the channels for it to exit from the sides are no longer there. So once the grooves are filled up, especially at high speed when the tires are outrunning the water that tries to escape, you are floating on water, that's it. Unless your car can walk on water, you need to slow down or get new tires, or both.

 

2006 550i - 6spd MAN

this exact thing happened to me last weekend - My tires were cheapos and im realizing that that was a bad move - no real damage except 2 of the screws on the fender guard popped out on the drivers side front and its ever so slightly sticking out past the fender (if anyone has advice on where to get screws like these id appreciate it )

i AM staggered with the 19" 166's from the M5 and i noticed that even light acceleration at 65 mph was making my rears spin - i am extremely stupid and had hydro'ed a few times over my 3 hour hell ride on interstate 88 before my wipeout, but was able to correct by laying off the gas and NOT BRAKING - just letting the car get straight again and feeling for directional grip. either way - the big one was a doozie - i am stupid for continuing to push my speed even though i thought conditions were improving, was only going 65, and felt familiar with the road. my rears started slipping and i let off the gas - a wiggle to the left, slight correction, a wiggle to the right (i most likely overcorrected slightly, give me a brake were talking milleseconds here), and then a little too far left - the car was gone and i left the road to the left at probably 50 mph, if straight ahead was 12 o'clock i was probably headed towards 10:45 when i exited the road, my car was twisted a little further than that, maybe to 10pm. ended up in the grass facing the other direction. felt like the bggest idiot- with those big tires you have to be very aware of your speeds in bad conditions - dont let the amazing capabilities of this car in good weather give you too much confidence in bad conditions - its still just rubber, water and asphalt.

 

Your first mistake was using the brakes.
The second was speeding along with KNOWN bad tires in the rain.
This is why Fark has a Florida tag.

 

Wide old tires with no thread left is the reason.

Narrow tires are better and the thread should never be less than 3 mm.
