I
doubt anyone should be pushing a Macan to the limit of decent all
weather tyres on a public road let alone summers in right conditions,
being concerned about a small difference in braking distance suggests
foccusing on a single figure out of context, you can normally get far
more safety by leaving a second extra gap and that adds the extra
advantage you are less likely to be hit from behind as you won't be
braking harder than the person behind can (yes I avoided hitting
something by quite a margin, car behind didn't though).





^This








You can disable all
the airbags also, because most Macan owners drive so slow and careful
that they won't be needed anyway...




Driving
slowly doesn't mean you are driving safely, driving safely
doesn't mean you have to drive slowly (unless circumstances dictate
you need to) - driving safely is about managing risks and you can go
fast and have an enjoyable drive without increasing risks
unduly,.



Unfortunately people don't know how to judge
risks and the factors very well - instead they generally focus on simple
things and do substitutions - e.g. they seen 80% shorter braking
distance and that sounds to them like 20% safer and who wouldn't
want to be safer, but it is far more complex than that.



Personally I hate
traffic, but even worse is being in a queue of cars with insufficient
braking distance between them - it raises stress and sucks all the
joy out of driving, so when in traffic I tend to just leave large
braking gap sit back and enjoy the music - give me an open road
with no/little traffic and you can enjoy the drive and the car and
there is less worry about things like ultimate stopping distance as
roads are clear.

I believe my instructor at PEC was of the opinion that unless you need winters and so have to change at some point most will never push hard enough to notice any difference

Funny that my kinda ironic provocative notes in here engaged some emotions. At least touched some toes LOL

My instructor at PEC was also of the opinion that all weather tyres were fine for those of us who live south of Watford

I got my Macan GTS a bit sideways on an ungritted road on summer tyres on my PEC day Confused

But at least my instructor was impressed that I collected it with no drama Smile

Dandock - I don't want to contradict a PEC instructor. I was massively impressed with their advice when I spent time in their company. I wouldn't want to tell them how to drive a car fast.

I would have pushed back on that comment though, from personal experience. The driving characteristics of a winter tyre is massively different to a summer tyre (and is has to be as it was designed to). There is the difference in rubber compound for starters. The tread blocks are smaller with extra sipes to dissipate water. These sipes also generate heat (which will destroy the tyre during warm summer driving). The biggest difference though is the side wall and the pliability of it. When driving at legal road speeds, taking a corner or roundabout at summer speeds (on a dry road) will soon make you realise that you are pushing your luck. A winter tyre compresses and rolls to such an extend that you are out of control even within the speed limit envelope.

Hi John M your post on keeping a safe stopping distance gives you a distinct advantage if for any reason you have to brake hard and less likely for the idiot tailgater hitting your vehicle and all the trauma that ensues

All seasons are not winters so the PEC instructors comments are probably quite valid. I have used full winters on my M3 for 5 years (Same set )and they have never come even close to losing control. Also drove a 458 with full winters around Maranello at double the speed limits of those in the UK and never had any issues.

Contrary my PEC Instructor said All Seasons were better.

He then proceeded to give me a few laps with him driving and him doing different lines to those I was doing.

When I did those same lines in all cases except one I was not as well balanced and far slower than I was doing my own lines.

So no PEC Instructors do not know it all.
