I did follow the instruction as per manual: 90 degree penpendicular inside tire and then turn 90 degree. I finally did it but I guess I will take the advice to apply vaseline.
I give you a hint. You don't just pushing the wheel in the tire. It is more of pulling the tire in the wheel by holding the side of the tire with your thumb and index finger.
Oh my god, I do have the same problem. I did the frog and buggy champ before, but not SS. I had tried for the whole night, both fingers were so painful.
Bro Peter, when will you go to KWS, I really hope you can help me!!
