Handling dry (2770 m track):

B-stone RFT: 1,17,0 min
B-stone Std: 1.19,4 min
PS2 RFT: 1.17,4

Handling wet (2300 m track)

B-stone Std: 1.44,7 min
PS2 RFT: 1.44,2

Tire is a component of the entire suspension system. The example above shows only the results on this one particular vehicle. A different vehicle with different suspension system could have completely different results for these tires.
