While track day tires are sometimes unusable in wet conditions, they provide excellent grip when everything is fine and dry. It is inevitable that the more blocks of tread you remove, the more hydroplaning you will have. In his latest video, Jonathan Benson of Tire Reviews takes a detailed look at the differences between the Michelin Cup 2 and Cup 2 R tires fitted to a Porsche GT3 RS.
The French shooter granted Benson the use of his testing center in Ladoux, France. Located just north of its Clermont-Ferrand office, the site offers 20 test circuits and 45 kilometers of tarmac to play. Like many tire test sites around the world, the tarmac can be soaked at any time to gain insight into wet weather driving characteristics.
As such, wet handling was first examined on the Cup 2 tire. Sure, you could say it’s a bit silly, but hit a sudden storm on your way home after a day. track with these tires is a real possibility. The biggest difference between the two is the Cup 2 R’s additional lack of tread and depth, which makes it very difficult to handle in the rain.
While it might not handle wet weather as well, the Cup 2 R was designed with Porsche to propel the GT3 RS into the fastest possible time around the Nürburgring; these technical prowess are reflected in performance in dry weather. What the high quality tire lacks in degradation it makes up for with outright speed. Although Cup 2 provided excellent results, Jonathan Benson of Tire Reviews said the Cup 2 R’s braking performance and grip were much better.
While these two tires are extremely capable and fast, they are designed for two very different purposes: the Cup 2 R is great for pure speed, but its little brother is the best tire if you drive your track car daily.
