the track seasons nearly here, infact my first trackday is this saturday weather permitting, so i went to my local perrelli perforamance centre and enquired about mich ps2, upon getting their i managed to strike an amazing deal, last set of ps2 in stock, free fitting and trade price on the tyres. i went with the same choice of size 235/35/19 265/30/19. The service at these centres is fabulous, my car was treated like it was their own, no one ding on any of my wheels, i even got a print out with each individual wheel bolt torque, tyre weight and all wheel weights done in perfect uniform, hugely satisfying to see these guys working on my car. Right now down to the tyres, the sidewall on these ps2 are very hard, i was just wondering what tyre pressures people are running with ps2s???? after leaving the centre i went round a steady 30mph corner and completely shat myself as my car proceeded to 4 wheel drift right into the path of an incoming bendy bus, serious brown trouser moment, im really looking forward to comparing these tyres to the vreds and conti's!! first thing ive noticed is a very stiff/beefy sidewall which offers great rim protection

if any of you guys are looking for the best for your car try a PPC, they really are fab!! top marks boys!! any idea on pressures please guys????

i really wanted ps3 but i couldnt get them in the size i wanted.
 
New tyres - the surface needs scrubbing in. Tyres are comprised of layers of rubber, steel and fabric. Due to these different components, new tires require a break-in period to ensure that they deliver their normal ride quality and maximum performance. As tyres are cured, a release lubricant is applied to prevent them from sticking in their mould. Some of the lubricant stays on the surface of the tyres, reducing traction until it is worn away. Five hundred miles of easy acceleration, cornering and braking will allow the mould release lubricant to wear off, allowing the other tire components to begin working together. Surprised PPC didn't tell you that. I run PS2s and use the BMW recommended pressures with no problems and even tread wear across the full width of the tyres which suggest the pressures are about right. Ran them on these pressures at The Ring and whilst not being too adventurous grip and handling were excellent.
 
yeah i know you have to be careful with new tyres but i just got caught out!!

also regards the tyre pressure dont forget im on CSLs, not the original 18s. just to clarify what are people using on 19s??
 
Contact Michelin or even PPC they should be able to give you the recommended pressures. PPC will have used some guide to inflate them when they were fitted (I hope it was not just guess work on their part). If not a good start is F34 R37 - the BMW recommended for 18" and then experiment with small variations.
 
There won't be any recommended pressures for these cars on 19's. I run the PS2's in these sizes at 33psi rear and 32 front which works well for me.

dgm - have you asked?
 
I have indeed Alan, when I first got the CSL's a couple of years ago Costco were fitting the PS2's for me and were baffled by the fact that the 19's weren't listed for the car. As you know they're closely linked to Michelin and have all the relevant data to hand. The 19's on a Z4M are in effect an aftermarket fitment so wouldn't feature in any official pressure chart. They can give you the recommended pressures for an M3 CSL on these tyre sizes (265/30 & 235/35) but that doesn't necessarily translate to a different car.
 
daft question, but putting the obvious driver benefits to one side of non RFTs but what if you get a puncture without a spare? waiting for roadside assistance is always a real option.

Yes agree - axle weights would be different but perhaps a good starting point.
 
sherlock, /Ms have a mobility kit that has a tyre pump and a bottle of tyre goo. Whether the owner would use it is another thing. I've used the pump but wouldn't use the goo.

dgm can you recall the pressures used by the CSL?

From memory I think that most CSL owners ran about 33/34 rear and 32 front, most of them initially came on Cups though. If the car is being tracked then you would have to go down a few pounds to allow for the extra temperatures generated. I run my Cups and PS2's around these temperatures and it feels right to me. You just have to experiment a bit but I wouldn't go much higher than these pressures personally.

Andy,

Cheers for that, I assume then I could buy a compressor and 'goo' and go no RFTs on my 3.0 Si then?
