Different pros: For the season 3k. not a single spike fell out. First time I have this. True, he complied with the running-in conditions of -400 km at a speed of no more than 80-90. Just two trips to Finca. Has cons: At the recommended pressure of 2 atm, the feeling on the pavement is as if the car drives a little, as if the rear wheels are lowered. Even stopped, thought a puncture. Pumped up 2 dozen more and it became normal.
