Pirelli N-2 vs Michelin N-1 ?
- Thread starter Alex L
- Start date
Personally, I think tyres are very subjective, and there are so many variable, that it really isn't possible to determine what is necessarily best.
Also, a lot of times, owners rave about their new tyres when their direct comparison is with the 'old' pair that are being replaced. Inevitably the new ones should feel better.
The GT3 is a bit of an exception, where there are only two bespoke tyres - the Corsas and the Cups, and it's much easier to distinguish between their relative merits. The Corsas come with more tread and are better in the wet, with longer life. The Cups are regarded as better in the dry or on track.
Christophorus used to do an annual review of the N-spec tyres, but even this never seemed terribly scientific.

I think you definitely have a good point there. However, shouldn't a worn set of tyres have better/same dry grip as a new set given more or the same amount of rubber is touching the ground?
Saying that, I seem to recall Chris F telling me that as a tyre wears it effectively gets harder the closer to the cloth/metal layers you get, so you may feel a new set is softer. The only way to really tell I suppose is to change a new set of Michelins for a new set of Pirellis and compare [8|]
Update:
The new Pirellis are still getting much higher pressures when fully warm even with N2 in them.
They are starting at the following PSI when cold (note this is from the TPMS not direct measurement):
30 - 30
36 - 36
(the actual pressures are 34 and 40 PSI when cold)
And going up to the following PSI when warm:
36 - 36
42 - 42
Compared to the old Michelins that when warm were always bang on:
34 - 34
40 - 40
It does seem that the new N3 Pirellis make a lot more heat than the N2 Michelins.
Also, when cornering the Pirellis feel softer somehow and not quite so stable as the Michelins. Don't the Michelins have some kind of side wall protector than the Pirellis don't?
So in conclusion I think next set of tyres I will spend the extra money and go with the Michelins. Shame the PS3's aren't going to be N rated in the next year or so though.

Sorry N2 indeed, my brain is not up to speed yet this morning. There goes my degree in Biochemistry and Biological Chemistry out the window!
The N2 was great in my old Michelin tyres, it doesnt seem to be having much effect in my Pirellis. This could either be because the Pirellis heat up more, or because when they were re-filled with N2 it was a damp day (moisture got in) or one air purge is just not enough, it needs to be repeated several times...

Maybe they should try N2 instead - it may be more stable![] So the N2 doesn't seem to be worth the effort Alex?
NO2?
Alex always enjoys a good laugh!
Pirelli use a mould releasing agent that gives the tyre a rather skittish feel for a around 500 miles.
Heat-wise, Alex, maybe you need to increase all round pressures slightly.

Where's a chemist when you need one, and I don't mean Boots! I think the gas to which you refer, dear Clive, is N2O![ORIGINAL: Lancerlot
