What tire size to get for high offset 19in wheels

I was wondering what tire size some of you recommend for regular fitment of 20" staggered wheels.   Fronts will be 20x8.5 and rear 20x10.  Offset around low to mid 30s.     Wondering what tire size would work for Infiniti Q45 F50.     Thanks.

With the swift springs, those sizes should be close to flush. You will still need to roll or cut the insides of your rear fender lips if you already have not.
 
I was running a similiar setup 3 years ago. I had 225/35's up front and 245/35's in the rear. I had lots of rubbing until I cut the rear inner fender lips. After that, no rubbing.
