On the front of what car?
If A-body I think you’ll find an 8 or 8.5 will be too wide. Causing tire rubbing issues on the bottom corners of the fenders. I think you’ll find 7" to be about as wide as you’d want to reasonably go. Even 6 or 6.5 if anyone makes a 6.5
If you’re running front runners right now anything will be a handling improvement.
