You can choose either of those dimensions. I would choose 295/30.

Ultimately it depends on what size front tire you are going with.

The 305/25/20 is too small diameter. All the tires that you would be mounting to the front 10" wheel would be larger in diameter than the 305/25/20. The rear tire ideally needs to be 0.5" to 0.6" larger diameter than the front tire.

In a perfect world, I would think the 275/30/20 front and 305/30/20 rear would be your best bet for those width of wheels.
