Peter Hewson, the head of tires for the Caterham Formula One team goes in depth to explain the differences between the 2012 and 2013 Formula One tires as supplied by Pirelli.
Just as the teams got used to the 2012 compounds and how they worked with their own cars, Pirelli went back to work and changed things up for 2013 in an attempt to keep the teams guessing and to try to keep the racing as exciting as possible.
I’m not sure about you, but for me all the messing around with tires has added a level of confusion to watching F1 races. You are never quite sure of where everyone is at with their tire strategy or wear. On one hand it keeps us guessing to see if things change late in the race, but at the same time drivers are moving up and down the leaderboard like crazy and it all gets difficult to keep track of.
Anyway, here is some great insight into the world of Formula One tires.
