Pirelli's motorsport director Paul Hembery has repeated at Korea that F1's sole tyre suppliers need to have more relevant tyre testing if it is to develop solid and reliable tyres for the 2014 season.

That's assignment after the wheel was mounted, sprayed/written on the rubber after the wheel is assembled and balanced. Tyre kits are numbered and fixed, that's how the LT app knows how old is even used rubber on cars.Diff-user wrote:err...

He means the Pirelli stated one that is next to the barcode. The red R is what teams put on there. Have you not read any of this thread?Diff-user wrote:err...

... Well I have been following this thread for a few months now, just that I didn't know that the teams sprayed the side on a tyre after they tyre was fitted. My bad.
I might have not been clear: they promote it while they prohibit it in F1. Everyone who drive pirelli road tyres and swapped tyres will now give the whole thing a second thought.Blanchimont wrote:http://www.michelinman.com/tires-101/ti ... ation.page
It's a common practise to swap tyres on road cars!
I think that's the markings that the teams put on - not by Pirelli.Diff-user wrote:err... So whats the big red "R" with an arrow?stefan_ wrote:Picture from Germany - the tires don't have the marking that tells which side they go on.

Yes you are right; the source I used was wrong on the compound. So I assume they will be allowed to swap tyres again from that point on.Holm86 wrote:You're wrong. The tires used from the Hungarian GP forward will use 2012 construction and 2013 compounds.turbof1 wrote:-At Germany they will run 2013 rear tyres with the 2012 kevlar belt.

-At Hungary, they will effectively run 2012 tyres, front and rear. So from that race on, nothing from the 2013 tyres will be taken over.
That means, from Hungary on:
-softer sidewall
-harder compounds
-kevlar belt instead of steel belt
It could very well be that plans are still going to change. Pirelli will test several solutions at the YDT. So we'll have to wait and see, but for now this how it will go.
"1) The use of the evolution of the current tyre that was tested in Canada (and proved to be completely reliable) for the German Grand Prix this weekend. This represents the best match for the technical characteristics of the Nurburgring circuit. In particular, the rear tyres that will be used at the German Grand Prix, which takes place on July 7, have a Kevlar construction that replaces the current steel structure and the re-introduction of the 2012 belt, to ensure maximum stability and roadholding. Given that these tyres are asymmetric as well, it will be strictly forbidden to swap them round. The front tyres, by contrast, will remain unaltered.
2) From the Hungarian Grand Prix onwards, the introduction of a new range of tyres. The new tyres will have a symmetrical structure, designed to guarantee maximum safety even without access to tyre data – which however is essential for the optimal function of the more sophisticated 2013 tyres. The tyres that will be used for the Hungarian Grand Prix onwards will combine the characteristics of the 2012 tyres with the performance of the 2013 compounds. Essentially, the new tyres will have a structure, construction and belt identical to that of 2012, which ensured maximum performance and safety. The compounds will be the same as those used throughout 2013, which guaranteed faster lap times and a wider working range. This new specification, as agreed with the FIA, will be tested on-track together with the teams and their 2013 cars at Silverstone from 17-19 July in a session with the race drivers during the young driver test. These tests will contribute to the definitive development of the new range of tyres, giving teams the opportunity to carry out the appropriate set-up work on their cars."

As I'm completely lost here WB, can you please xplain why professional teams don't get the position of their tire's right?stefan_ wrote:Picture from Germany - the tires don't have the marking that tells which side they go on.
