Bridgestone tests a green marking for ‘soft’ slicks

We remember the Japanese Grand Prix from last season, where Bridgestone tested a marking system for Soft Tire / Hard Tire, which was quite original. The soft tires had their grooves colored green, instead of the traditional white. This system allowed them to be distinguished from the hard tires, which were more durable but less performant.

This year, the FIA has re-authorized slick tires for the first time in 11 years. Drivers will therefore have more grip on dry tracks. But just like last year, two types of tires are offered: soft and hard. To differentiate between the soft slicks and the hard softs, Bridgestone had to put their thinking caps on.

Indeed, wet or intermediate tires have grooves. Thus, they can easily be painted for marking purposes. With slick tires, which are by definition smooth, any marking would have vanished after just a few kilometers.

Bridgestone has therefore found a workaround. The Japanese manufacturer is currently testing a new marking system in Jerez, along with the teams present this week. Instead of coloring the grooves, which are absent, a green stripe surrounds the sidewalls of the slick tires.

This system is still in the testing phase, but it seems to be suitable. There are therefore two green-colored stripes for each tire. Why green? To raise public awareness about environmental protection, as Bridgestone intended last year.
