Lowenhart 20" tire recommendation

I got my hands on some Lowenhart 20" Br-5 wheels and was looking for some ideas as far as a tire brand and size fitment from the forums.  :biggthumpup: Any help would be of great help.  I have an Infiniti M45 2008 the wheel measurements are as follows:

20x8.5 +38
20x10.5 +42
