The outstanding performance of Michelin high-performance tires is well known: PS4S performance street tires are comprehensive, Cup2 tires can take care of some tracks, and Cup2 R pursues extreme lap times.
But what is the actual gap between the three of them?
"Sportscar" used the Porsche 991.2 GT3 RS as the test car this time, equipped with these three tires for comparison tests on the test track. For high-performance tires, the judging criteria on the track are: dry grip, corner speed and durability. However, from the perspective of street cars, wetland performance must also be considered, because when running Trackday or returning from the track, it is likely to encounter rain. BTW: Special thanks to @pkpk1 for the material and original translation!
[Price comparison]
Pilot Sport Cup 2 R: 2,238 Euro
Pilot Sport Cup 2: 1,354 Euro
Pilot Sport 4S: 1,054 Euro
this The price is a set of four, 991.2 GT3 RS tire specifications are front 265/35 ZR20-rear 325/30 ZR21.
[Dry ground speed test]
Pilot Sport Cup 2 R: 1 minute and 08 seconds 50
Pilot Sport Cup 2: 1 minute and 10 seconds 20
Pilot Sport 4S: 1 minute and 12 seconds 10
in this 2.74 km On a long dry track-
Cup 2 R: In corners, there will be neither understeer nor tail slip. It is the tire that can best play the potential of GT3 RS. However, the fastest lap time can be achieved only in the first two laps, and then the grip starts to slowly decrease, but it can still maintain a higher grip than the ordinary Cup 2.
Cup 2: is the most balanced, with slight understeer in slow corners, slight tail slip in high-speed corners, and a stable lap speed can be maintained even after multiple laps.
PS4S: Although it is 4 seconds slower than Cup 2 R, it has the best durability. After ten laps, the tread still looks like new. The grip is moderate, and there will be no serious understeer and oversteer.
[Dry ground 100km/h-0 brake test]
Pilot Sport Cup 2 R: 28.7m
Pilot Sport Cup 2: 32.6m
Pilot Sport 4S: 33.3 meters
Emergency braking under 100 kilometers per hour warm state——
Cup 2 R：It can still maintain 28 meters after 4 consecutive emergency braking Level. What's interesting is that the degree of deceleration is so strong that even the PDK gearbox sometimes has no time to make a supplementary downshift, and even skips the middle gear directly!
Cup 2: 's performance here was not satisfactory, and Cup2 R opened a gap of nearly 4 meters.
PS4S: performance is full of surprises! She is almost the same as Cup2, and the ABS control of GT3 RS also fits this set of tires well.
[Wetland lap speed test]
Pilot Sport Cup 2 R: 2 minutes and 05 seconds 10
Pilot Sport Cup 2: 1 minute and 48 seconds 80
Pilot Sport 4S: 1 minute 42 Second 10
on another slippery track with a total length of 2.27 kilometers-
Cup 2 R: is totally another world. Try to run 5 laps to complete a lap without losing control. Whether it is in a straight line or in a curve, the vehicle will float up and sway left and right. As long as the speed exceeds 95km/h, even walking in a straight line is a problem.
Cup 2: here shows extraordinary wetland handling performance. In medium-speed corners, the front of the car responds well and the rear of the car is very stable; only in narrow corners will there be a more serious push, but it can be slightly corrected by controlling the rear of the car by the throttle. When it exceeds 120km/h, water skiing will occur completely.
PS4S: Although it is not customized for GT3 RS, it shows excellent steering response and rear axle grip in wet ground. The driver can easily take the ideal route to attack the corner, cleverly control the slip degree of the rear of the car, and the braking point can be later. Only when the vehicle speed exceeds 160km/h will complete water skiing occur.
A good horse with a good saddle, a good car with a good tire! Friends who are keen to work on horsepower and braking, may wish to change the tire before doing it!
