Every time I have tires put on my S2000 I eventually feel they are out of balance and then realize that I've shifted the wheels inside the tires. Its happened with OEM 16"s and now OEM 17"s and with multiple different tires. Does anyone else have this happen? And what can I do about it. I watched the tech use soap to put the wheels on, maybe its to much? Hes a Porsche tech so I figure if anyone should no what their doing it should be him.

 

Rim spin is typical in performance applications. The slick used to mount tires dries extremely fast and will not cause a balance issue unless the tires are left mounted before having the beads seated. Enkei actually makes a pattern on the bead seating area of the barrel to try and prevent this, I saw it on my RPF1's.

 

I have seen people do it here that have tires mounted and then go autocross.
