E46 330Ci + New Rear Tyres: Unstable
Discussion
I forgot to say that the handbrake + DSC light turned themselves off the next day.

But I have one question and it will sound silly. Are the tyres fitted in the correct orientation? I.e The outside of the tyre is facing outside.
Not a silly question at all. Yes, I've double checked and they're facing the correct way (including the direction of rotation).Edited by SebringMan on Thursday 13th July 07:52

Now that I've driven with the PS4s for a while longer, I've noticed that it's very easy to break traction. For example, there's a sharp bend on a hill near my house, so I always take it in 2nd and accelerate as I come out of it.
With my previous PS2s, I never managed to get the car to slide. With the PS4s, it slides every single time.
Can bad wheel alignment after the tyre change cause such traction issues?

I had exactly the same issue on my E46 330ci.
Changed the rears only and certain corners which I'd take at a moderate speed on my daily commute were all of a sudden triggering the stability control. As soon as I changed the fronts so they were matching all round (Falken FK452 iirc) the problem disappeared. Was a few years ago now but the Falkens proved to be a decent tyre for both grip and longevity (seemed to be a popular tyre in M3 circles at the time too)

I might just change the fronts as well and will report back.Changed the rears only and certain corners which I'd take at a moderate speed on my daily commute were all of a sudden triggering the stability control.

You said you changed the rears, but what's on the front.
Bridgestones?
Fronts are PS2s (all four were PS2s but only changed rears to PS4s).Bridgestones?
On an E46, with its reputation for being tyre sensitive, that could cause all manner of handling issues.
Have you tried swapping front to back?
Following the recommendation of another thread on here I have a set of Pilot Sport 4's on my 330ci sport, going from a pair of well used Pirelli's and a mismatched pair of ditch finders, totally transformed the car. I can't compare them to Pilot Sport 2's but they seem to have bags and bags of grip and the car is sure footee crusing the motorway or nipping round small roads.
Originally the cars was on the staggered 18" which drove ok on a none matching set of Bridgestones but I swaped to 225/45x17 all round on cost and comfort gorounds as my commute is 20mins on the back lanes.

As per dhutch they have been superb with me as well.
As a final thing where did you have them fitted? The only things I can think of affecting them from the manner you've said in this thread are:
-Made in another country ; This caused an 'illegal' set of of Eagle F1s to once enter the country ; the Chinese ones were made for hotter climates that the UK (think India etc.) where they were lethal in the UK.
-Contaminated with diesel ; It's unlikely but you never know.

Got them fitted at KwikFit (not the greatest place but very close to where I live), so I think they're genuine PS4s.As a final thing where did you have them fitted? The only things I can think of affecting them from the manner you've said in this thread are:

One thing I found quite strange after the new tyres were fitted is how much they were are sticking out, I've never seen anything like it on another car. Can anyone confirm if this is normal?
Back tyres (PS4s):
Front tyres (PS2s)

The rears appear to be wider than the fronts? Was this a square or staggered setup?
It's the standard staggered setup (255/35/18 at the rear and 235/40/18 at the front). Even though the PS4s are the same size as the PS2s they replaced, they do appear to be sticking out further.Okay, so I just changed the front tyres to a new pair of PS4s, so now the whole car is running a full set of PS4s all around.
Unfortunately, the problem has not gone away. The stability control + handbrake warning lights keep switching on regularly now.
During the wheel change, I asked the garage to get the wheels aligned as well. Turns out, they were badly misaligned and furthermore, they couldn't adjust them because everything was seized.
So now I'm considering my options. I can either refresh the suspension on all four sides and keep the car for a another few years or I can just buy something else. Given the amount of hassle I've gone through, I might just drop it at a main dealer if they can sort it all out, even if it means paying a premium for the convenience of not having to keep going around garages every weekend.
