Staggered Tire Recomendations

[Bruisbe]

Ok, I just ordered some 18x9 rims and are trying to decide the tire size to go with.

Keep in mind that I have lowered my Mach just over an inch.

I have been toying with different ideas.

245/40/18 in front
265/40/18 in back

245/40/18 in front
275/40/18 in back

255/40/18 in front
275/40/18 in back

Those are the different options that I have priced out, however if you have different suggestions, please offer them up. When it comes to some of the staggered setups and lowered/larger tires, anything besides OEM starts to get muddy for me.

Thanks in Advance!!!
