17 inch offset question to fit 225/45ZR-17 ( S13 )

[Paul_Ward]

I am trying to run max size tire for my autocross class that is allowed, which means I need a 17 inch wheel to use the tire I want. Any one know what offset I will need?

what width?

Way too many variables here to work with. What suspension setup do you have? Stock brakes? What are your restrictions in your class for wheel width/offset? Just a few of the questions that will determine what you can get away with.

Ah! Suspension Technique springs, Suspension Technique sway bars, AGX Shocks, Stock brakes. STS rules state max tire size of 225 width.

Thanks Grant.

WHAT WIDTH?

what is the max width you can run in your class?

You can squeeze a 225 on a 7" wheel or stretch it onto a 9" wheel.

7.5

get a lower offset. 10 to 20 i'd say.
