wheel size question

[Lony kinney]

i have an 84 buick regal now and im wondering what offset do i need to run a 28-10.5 15 slick.

do you still have the factory 7.5 or have you changed to something else?

 

[Lony kinney]

same factory 7.5

i am pretty sure its a 15x8" rim with 3.5'' of b/s

 

[ralphl]

that sounds about right unless you notch the frame or change to a different rear in like and 8.5 or 12 bolt
