I have never had the sk to compare them to the SS. I have the gravelking SS I don't remember them being any different than other tires I have mounted. gp5000 ( sizes 23, 25, 28, 32), VITTORIA RUBINO, Schwalbe G-One gravel tire, giants factory gravel tire.

The rim though..... My gf has a
SCOTT Speedster Gravel 10 Bike
Rims Syncros Race 24 Disc 28 Front / 28 Rear

those rims for what ever reason I used the Kool Stop Tire Bead Jack to help install the tires. Luckily that bike is now mounted on her trainer.
