Duh, my bad . Too late to fix it.

 

Pagani Huayra’s Top Gear Lap Time Sparks Controversy | Motorward

"The controversy first started at TeamSpeed forums, where geeks analyzed the pictures of the Top Gear shoot posted on Flickr and noticed the Huayra that the Stig drove had different tires than what Pagani states on its website."

So I'm a geek now? I always thought of myself as a nerd...

 

Geeks!!!..... But those websites always come to TeamSpeed for info. Bunch of loosers!!

 

There was no clarification offered by Pagani:

The questions which needed "clarification" were:
-Why did the second set of tires have slick wear indicators?
-Why did the second set of tires have slick tire nomenclature?

Pagani said:
"1. We used both during the shooting at TopGear Test track. We reported Pirelli Pzero Corsa on our press release because we want, for communication reasons, to push them on the media."

Do people not realize this in of itself is a lie? Proving performance with a "Trofeo" then telling people it was a Corsa for marketing reasons is lying. However, this is just a lie on top of the bigger issue of them using cut slicks. They told people something false in order to make them believe something. How is that a reasonable justification for ANYTHING?

"2. All Pirelli tyres for the Huayra have been developed from the Zonda R (keep in mind both cars the Huayra and the Zonda R share basically the same suspension with the Zonda R being the development test platform for suspension, brakes and tyres of the Huayra). Pagani released statements about this in the past."

This was a they response to the question surround the P-Zero Trofeo tire they claimed to use. How is this provide any explanation? The Trofeo tires have street wear bars and street nomenclature - because they ARE street legal. The tire in the pictures has wear dots and slick nomenclature - both identical to the Zonda R slick and are NOT street legal.

It amazes me how people just accept things in lieu of evidence. All Pagani or Pirelli would have had to do, is provide the certification (if they had it).

It was also comical to see Jalopnik praise Pagani for their "openness" and "honesty." Crazy...

 

Very basic at this point -- from Wikipedia:

DOT code In the United States, the DOT Code is an alphanumeric character sequence molded into the sidewall of the tire for purposes of tire identification. The DOT Code is mandated by the U.S. Department of Transportation (my emphasis added). The DOT Code is useful in identifying tires in a product recall.

The DOT Code begins with the letters "DOT" followed by a plant code (two numbers or letters) that identifies where it was manufactured. The last four numbers represent the week and year the tire was built. A three-digit code was used for tires manufactured before 2000. For example, 178 means it was manufactured in the 17th week of 8th year of the decade. In this case it means 1988. For tires manufactured in the 1990s, the same code holds true, but there is a little triangle (Δ) after the DOT code. Thus, a tire manufactured in the 17th week of 1998 would have the code 178Δ. In 2000, the code was switched to a 4-digit code. Same rules apply, so for example, 3003 means the tire was manufactured in the 30th week of 2003.

Other numbers are marketing codes used at the manufacturer's discretion.

E-mark All tires sold for road use (my emphasis added) in Europe after July 1997 must carry an E-mark. The mark itself is either an upper case "E" or lower case "e" – followed by a number in a circle or rectangle, followed by a further number. An (upper case) "E" indicates that the tire is certified to comply with the dimensional, performance and marking requirements of ECE regulation 30. A (lower case) "e" indicates that the tire is certified to comply with the dimensional, performance and marking requirements of Directive 92/23/EEC. The number in the circle or rectangle denotes the country code of the government that granted the type approval. The last number outside the circle or rectangle is the number of the type approval certificate issued for that particular tire size and type.

I'm sure the Huayra's Power Lap "Trofeo" tires carry these basic codes at least, since we've been told they are street legal, no?

I've reached out to a few sources for further insight on road-legal tire construction and nomenclature. Awaiting responses.

More to come.

"Federal law requires tire manufacturers to place standardized information on the sidewall of all tires. This information identifies and describes the fundamental characteristics of the tire and also provides a tire identification number for safety standard certification and in case of a recall."

U.S. DOT Tire Identification Number This begins with the letters "DOT" and indicates that the tire meets all federal standards.

3.1.3. An indication of the structure as follows:

3.1.3.1. on diagonal (bias-ply) tyres, no marking or the letter "D" placed in front of the rim diameter marking;

3.1.3.2. on radial-ply tyres, the letter "R" placed in front of the rim-diameter marking, and, optionally, the word "RADIAL";

3.1.3.3. on bias-belted tyres, the letter "B" placed in front of the rim-diameter marking, and in addition the words "BIAS-BELTED";

3.1.3.4. on radial ply tyres suitable for speeds in excess of 240 km/h but not exceeding 300 km/h (tyres marked with the speed symbol "W" or "Y" as part of the service description), the letter "R", placed before the rim diameter code marking, may be replaced with the inscription "ZR".

3.1.3.5. on "run flat" or "self supporting" tyres the letter "F" placed in front of the rim diameter marking.

3.1.4. An indication of the tyre's speed category by means of the symbol shown in paragraph 2.29. above;

3.1.4.1. On tyres suitable for speeds in excess of 300 km/h, the letter "R" placed in front of the rim diameter code marking shall be replaced by the inscription "ZR" and the tyre shall be marked with a service description consisting of the speed symbol "Y" and the corresponding load index. The service description shall be marked within brackets, for example, "(95Y)".

The document quoted at top goes further to explain the size labelling requirements:

2.17. "Tyre-size designation" is

2.17.1. a designation showing:

2.17.1.1. the nominal section width. This width must be expressed in mm, except in the case of the types of tyre for which the size designation is shown in the first column of the tables in Annex 5 to this Regulation;

2.17.1.2. the nominal aspect ratio except in the case of certain types of tyre, for which the size designation is shown in the first column of the tables in Annex 5 to this Regulation, or, depending on the tyre design type, the nominal outer diameter expressed in mm;

2.17.1.3. a conventional number denoting the nominal rim diameter and corresponding to its diameter expressed either by codes (numbers below 100) or in millimetres (numbers above 100);

2.17.1.4. the letter "T" in front of the nominal section width in case of T-type temporary use spare tyres;

2.17.1.5. an indication of the tyre to rim fitment configuration when it differs from the standard configuration.

 

Also from the above referenced document:

6.3. Tread-wear indicators

6.3.1. The pneumatic tyre shall include not less than six transverse rows of wear indicators, approximately equally spaced and situated in the principal grooves of the tread. The tread-wear indicators shall be such that they cannot be confused with the rubber ridges between the ribs or blocks of the tread.

Also:

6.2. Load/speed performance test

6.2.1. The pneumatic tyre shall undergo a load/speed performance test carried out by the procedure described in Annex 7 to this Regulation.

 

Sorry for the multiple posts guys. Just putting this stuff on here as I find it, highlighting what I feel are the most relevant points I've discovered so far.

It's enough that Pagani has stated that the Power Lap tires were modified Zonda R racing slicks. It's the assertion afterward that they were in some way street legal that I've had a problem with.

As far as I can tell, the Huayra's Power Lap tires are absent of the required markings, and furthermore lacking the mandated in-groove style treadwear markers. At this point we have a pretty good foundation for the argument that the Power Lap tires as they were presented were in fact NOT street legal, as held to the requirements referenced above by the ETRMA.

Without getting into whether the Power Lap tires were ever subjected to the mandatory Load/Speed Performance Test, it's pretty easy to conclude that you cannot create a street-legal tire by cutting grooves into a racing slick.
