I tried searching but couldn't find a definite answer.

RAYS Engineering website list +37 front and +39 rear as the proper offsets for 18 X 8.0 and 18 X 9.0, but I am wanting to go with 1" wider front and rear, so I don't know what offsets I need.

Here are the avilable offsets

I'm thinking +37 front with 18 X 9.0 and +45 rear with 18 X 10.0.

Please let me know what you think.

Sorry for all these questions. I'm a newb here.
