Has anyone ran a 275 35 18 tire on a 18x9 wheel with 4.75 bs on a DSE sub frame?

I don't think that 4.75" back space will be sufficient. Here's why. I'm running a 275/35-18 on an 18x10 wheel with a 6.4" back space with my DSE subframe. With this setup I can just get my fingers between the tire sidewall and the fender lip. In order to keep the outboard wheel lip in the same position relative to the fender with an 18x9 wheel you would need a 5.4" back space. But since the tire sidewall will be a different profile on a 9" wheel I think you would need 5.5" bs for the tire to clear the fender lip or a 6" bs with an 18x9.5 wheel.
