High speed run - Germany
Discussion
Hi all,
I am taking the F10 M5 to the continent next week and going to try and see what it can do.
I have about 3mm left on the rears. My question is should I replace the rears prior to the trip. My thoughts are it should be quite dry and given it;s around 1000 miles, get them when I come back and use up the remaining rubber.
In the back of my mind is the niggle that given I will be getting up to 180+ would it better to be safe and replace?
They are Pirelli's btw, so not ditch finders.
Cheers

Have you inspected the full width of the tyres in some detail with the tyre off the ground?
If I ever let my rears go <3mm the inside shoulders are usually in a surprisingly worse state than is obvious when having a casual glance/feel. Certainly not conducive to fast autobahn driving.

Just bear in mind that the legal tread depth limit in the EU is 3mm. If you have and/or cause an accident the German Authorities will use this against you and it's unlikely to end well. I am taking the F10 M5 to the continent next week and going to try and see what it can do.

I'm there myself in 3 weeks and have just removed my fronts that are at 3mm for new ones. I kept them for use in the UK should i ever need them for track use etc.
You want to try and hit 180+mph and you're unsure about your tyres. Come on, you know the answer, get some new rubber, those are not speeds to be testing tyres at.
Where are you planning on attempting your high speed runs? I live just north of Stuttgart, with the amount of road works and sheer volume of traffic don't bother trying it anywhere near here. I often sit stationary on the autobahn pondering all those who have this idea that it is some sort of race track.

Having never done a Track day or driven in Germany my immediate thought on the title of this thread was similar to yours. Where are you planning on attempting your high speed runs?

Buy some new tyres and do a track day. Don't test your car on public roads. Do it in a controlled environment.

The 3mm is the worse case, probably have over .6mm in the centre on the inside of the tyre. If I ever let my rears go <3mm the inside shoulders are usually in a surprisingly worse state than is obvious when having a casual glance/feel. Certainly not conducive to fast autobahn driving.
For everyone else's benefit if I had any doubt at all these were dangerous I wouldn't have them on the car full stop. Maybe I am wrong in my thinking but I thought that the tread was more important for wet weather driving than dry conditions. I am not going to be hooning this in the wet so my question was, as long as I am not through the thread pattern anywhere, in the dry is there any reason why the tyre would be any more dangerous than one out the packet.
Also given I am comfortable with the handling of the ones I have on, better the devil I know than swap to a new tyre?
This is also not going to be my first time hitting over 160 or driving a powerful car.

I worked in Germany for many years and spent an inordinate amount of time pounding autobahns but there aren't too many I know of where they're straight enough, long enough or traffic free enough for 180+. Good luck finding one but IME high speed runs like this are a little bit boring. I assume there's other reasons you have for being there rather than just this?

Between here and Dusseldorf. There for a week so will have time to try a couple of options.Where are you planning on attempting your high speed runs?

I would change them personally.
I’ve gone from 3mm or less to new MPSS / MPS4S on numerous occasions (I’ve accrued 90k miles in my F10 M5) and am always surprised how traction is affected even on a bone dry road. It’s certainly not just about water displacement.
I’ve also seen 170+ on countless occasions and I know which state of wear I’d prefer my tyres to be in.

Yes friend's wedding. The car hits 160 without much effort or distance. I know the last 20 is going to take a some time to get there but want to see if it does actually have a limiter, as not found it yet! BMW themselves might stop me achieving this. I think the limiter is said to kick in around 175.theboss said:

Thanks for the sensible suggestion. Think I will get the new set. I’ve gone from 3mm or less to new MPSS / MPS4S on numerous occasions (I’ve accrued 90k miles in my F10 M5) and am always surprised how traction is affected even on a bone dry road. It’s certainly not just about water displacement.

That's the thing, Travelling at 3 miles per minute, you obviously cover a lot of ground getting the last 20mph. Where in Germany are you headed for?Gassing Station | General Gassing | Top of Page | What's New | My Stuff
