It is just co-marketing. Makes it easier for Pirelli (Italian company) and Lambo (Italian company) to sell you their tyres if you "need an L".
Michelin PSS, without an L, fit the Gallardo and others just fine.
Simply make sure the rolling radius is the exact same.
That makes no sense. There is no premium for the L marked tyre and Pirelli effectively do themselves out of a sale when the model specific tyres are not available rather than say .. "any PZero will do."Michelin PSS, without an L, fit the Gallardo and others just fine.

Rather than blindly spout nonsense, do a little reading.
Just make sure the rolling radius is within 1-3% and you're all good.
Lots of cars running just fine without "L" tyres (Michelin PSS, etc.).
But you must make sure the rolling radius is accurate, or it will screw the car and may cost thousands to repair.
Yipper - lots of talk about 'Rolling Radius'.
How do I check that on my existing tyres so I know what to get?
Also does that assume the Rolling Radius on the current tyre is as per manufacturer spec?
Final Question :-)
If I need 2 fronts, should I replace the rears at the same time?

its not the side wall stiffness unless you compare Porsche vs the rest but the compound that varies.... and the diff, traction control and other electronics accordingly programmed.....
lambo want a less hard wearing compound than audi that's more grippy but unfortunately less predictable in different conditions
re the 4wd cars, it is recommended all four tyres are changed together as the 'rolling radiuses' affect the diff....
there another thread in 2012 about this I contribute too and its a bit more experience based than technical

Thank you. The link to the other thread is useful. I think my main issue/point is there seems to be a general availability issue with P Zero Corsa L rated tyres (although I did find a little while back that ATS had both front and rear in stock for my car). On that basis, when the time comes to change, what does one do if there is no availability of that specific tyre?I accept that one should and I would change all 4, so based on general opinion, PSS4 would be a viable alternative? No idea what Rolling Radius is all about though....is that not just determined by the size and sidewall height? 295/35 etc.
Bearing in mind that mine is a LP570, the recommended tyre back in 2010 when that model was launched may have been Zero Corsa L, but tyre technology evolves and PSS4 is a much newer tyre than than the car itself, so can it not also be true that new tyre tech may widen the potential pool of options in this case?
I wonder if Kamak do an L rated version of their Slidewell Extreme or Ditchfinder Supers for Lambos these days?

Yes, circumference of wheel should simply reflect tyre width and profile but there is an accepted tolerance between manufacturers and this tolerance is greater than that permitted by the calibrations of the diff... the mich is actually very close to the Pirelli....
This is why it is not recommended to change a single tyre.... both on the axle is okay, or all four.... if one puts all four identical tyres that are out of tolerance than that might be okay but I'm assuming it affects some calculation in the ecu somewhere

I'd forget about corsas personally unless you can get the new design ones (tread pattern is different) but those I don't believe exist in the right sizes for the gallardo. The older corsa was a crap tyre imho on the road and on track. I'd go with the pss4 everytime but as 70proof says you'd likely want to be changing all 4 tyres at the same time.Bearing in mind that mine is a LP570, the recommended tyre back in 2010 when that model was launched may have been Zero Corsa L, but tyre technology evolves and PSS4 is a much newer tyre than than the car itself, so can it not also be true that new tyre tech may widen the potential pool of options in this case?
Never you mind said:
Slight bump. Anyone found the fronts yet for a Gallardo? Don't want Corsa just the normal PZero ones. I have about 1mm left all round
Try Black Boots in Chesham, Bucks. They are normally quite good at sourcing rare tyres.http://blackboots.co.uk/
Re-the tooling issues/costs for tyre manufacturers, the answer is yes, they really do build a different tyre for Lamborghini/Porsche/mclaren etc.... they have a myriad of choices for the belt bias, overlay, sidewall structure/stiffness, bead and a few more, and yes, they ARE all different. There are hundreds of possible combinations for a given tyre size and of course a tyre designed for a 911 with an engine hanging out the back is not going to be the same as for a mid-engined V10. Ask anyone who's driven a gallardo with N2 tyres..😁
Having visited the Pirelli production site for the high end tyres in Turin, I have seen the different types being layed up and moulded, each one corresponding to a specific need. So if you have the chance, a tyre factory visit is more interesting/educative than you can possibly imagine beforehand. Pirelli do have a production faclility in the U.K. I'm sure that clubs etc can organisé visits on special request.
