Not to get into any debates on balance , I have never put a set of slicks on without balance . I have used Hoosiers since 1995 . The guys that change them for me also race & it is true to use baby powder on the tubes . In the last 10 years it has taken more weight to balance . As far as returning them I never gave it another thought , they always ran smooth . Never had any of the horror stories about shake , or any other damage due to rear slicks . Gary
