Who gained/lost from the tire changes of 2013?

After the British Grand Prix, sole tire supplier Pirelli changed the construction of the tires in order to avoid future delaminating issues. The new construction was similar to 2012’s Kevlar designed belt but incorporated 2013’s tread—a hybrid of sorts. The Kevlar-belted tires ran 10-degrees centigrade lower than the initial 2013 steel-belted tires.

Sunday’s Singapore Grand Prix was a success with no delaminating tires and a healthy delta between the Prime and Option tire performance but five races on from the change, what can we deduce from the overall impact on the sport with this tire construction change? Has the issue been a success? According to Ferrari’s Fernando Alonso, it may be the very reason he’s 60 points adrift in the World Championship as BBC’s Andrew Benson reveals:

“We started (the season) in a good way. We were competitive in Australia, maybe not in qualifying but in the race we were taking care of the tyres very, very well, together with Lotus.

“We won in China, we won in Spain and then we seemed to lose a little bit of performance, especially when the 2012 tyres came back.”

One could argue that the loss of performance might be down to car development over the course of the season. With 1,000 design changes per week for Red Bull, it is easy to see how other teams might lose the development war that is a major part of Formula 1. Continued car and performance gains are made weekly in F1 and these incremental changes add up to serious gains on track over time.

Sauber have shown pace at Monza and Singapore and those two circuits are demanding in very different ways. The car set-up has to be low downforce for Monza and high downforce Singapore and this is a team with well-known financial struggles so winning at the development war isn’t part of the criteria.

Red Bull have certainly been on pace since the British Grand Prix with Sebastian Vettel winning 4 of the last 5 races. They do have the means to develop their car but have the new tires helped?

For Lotus F1, Kimi Raikkonen was doing slightly better pre-tire change. The Lotus F1 chassis is known for being gentle on the tires and it was Lotus, as well as Ferrari and Force India, who were very vocal in their frustration with the tire change mid-season. Kimi’s podium appearances have fallen off slightly since the tire change but is that enough to pin the performance dip on the tires?

Some F1 pundits suggested that Mercedes, who had a private test with Pirelli earlier in the year, were the team that would stand to gain from the tire change after the British Grand Prix. Driver Lewis Hamilton had 3 podium appearances prior to the British Grand Prix while his teammate, Nico Rosberg, had 2. Since the change, Hamilton has 2 podium finishes while Rosberg has not found his way on the podium yet.

Fernando Alonso had 5 podium finishes, including the British Grand Prix. He’s had 3 podium finishes since. Three 2nd place finishes at Belgium, Italy and Singapore. His wins at China and Spain are the key element in the equation but missing the podium 5 times is also a critical part of the math.

In the end, Sebastian Vettel has 5 podium finishes prior to the British Grand Prix with three of those on the top step. Since the retirement at Silverstone, he’s been on the podium at every race and won all but one of them. That’s the difference but is it really the tires?
