Yeah I had PS4S's on my C63S (first thing I swapped after getting it) - cannot wait to put them on this car, but can't justify the cost at the moment.

I have PS4S’s on mine, they have been embarrassingly “skippy” in the cooler weather… great when progressing but in slow turns, awful.

Its the geometry that causes that....the Ackermann effect.........not the tyres. Changing the tyres may well hide it....and you might not hear it....but it will still be there and will probably reoccur at a different temp, on a different surface or as the tyres wear down.

E46 m3 csl , thats the pinnacle of M3 ownership. What was your reason to let that besst go, lack of radio? I got myself an e93 m3 DCT in February to blow dry my hair around in. Had an e46m3 till 2019 and e46 330 before that and 645ci. The e9x is a very nice car, the gearbox is very decent for an old car and the v8 sings nicely

I honestly think that the E92 M3 is a better car than the CSL ... it sounds better and personally, I just felt its handling was superior. Then there's the V8 ... S54 is an amazing engine but a wound up S65 beats it. My CSL had a Supersprint exhaust ... I know its all about induction but the exhaust just gave the car an enhanced sound without being too loud. The E92 had a 1.5 exhaust mod .... again, subtle sounding.

I've never had an issue with the gearboxes, SMG or DCT .... IMO they were part of the cars character ... BMW manuals are hardly the best in class.

In reality, I doubt many CSL's were spec'd from the factory without a radio or aircon .. .thankfully mine had both

PS4S or PS4?

Pilot Sport 4 S have an exceptionally broad operating temperature range for an ultra high performance tyre but they will still skip in cold conditions. Everything that makes them exceptionally - no ridiculously - good for a road tyre means that they are flawed in cold conditions.

I’ve had a set of PS4S fail prematurely, whereby the tread blocks started to separate from the tyre. I suspect that may have been caused by using them all year round, including very cold conditions. I’ve previously said that it wouldn’t have put me off buying another set, but I haven’t yet!

It is the geometry, but all tyres will skip, but comfort orientated tyres with corresponding width, diameter, aspect ratio and sidewall stiffness simply flex and absorb the lateral forces avoiding skip. Tyres which aren’t sensible can’t.

Unfortunately relatively ordinary modern cars have ultra high performance tyres as the motoring press donnt rate cars which don’t feel sharp, and tyre manufacturers don’t make comfort tyres in the silly sizes required by stylists.

Years ago, only ultra high performance cars were fitted with ultra high performance tyres and these were typically either (1) not used in cold conditions, or (2) the driver understood the limitations, or (3) the driver fitted winter tyres.

Now we have people with ordinary cars, using their car all year round, who expects tyres to defeat the laws of physics and perform without compromise at all extremes, and doesn’t believe that winter tyres are required (in the UK).

Cars with greater negative camber - mostly performance cars and cars set up for stability, like most Mercedes models - suffer with skip more than others, because the camber is intended to resist lateral load for handling surety and performance.

You could test it by putting silly size wheels and ultra high performance tyres on any model which “never” skips, and then drive it at low speeds in low temperatures, and it will skip. The lateral forces have to go somewhere.

My wife's A Class W169 skips badly on multi storey type shiny floors... and that's with here balloon like tyres!

I got used to that a good while ago now, doesn’t really bother me. If the compromise for excellent handling in good conditions is skipping in cold conditions, I’m all for it!
