315/ 35 r20 tire on a 20x10.5

[blownby]

What offset will fit this? Or what has everyone used
Looking at on wheel that has a 45mm ET.
Should be close, as my current 9.5 wide wheel with 33ET and a 275/35 sits pretty flush...

I don't know of this helps but I have a 20x11 +55 and a 305/35r20 it fits flush with the fender.
