15x8 white spoke crager 205/60 r15????

hi all just finished doing a clutch job on my truck and re indexing the torsion for a good drop. The rear is still stock and have debating whether to get 4" or 3" lowering blocks but anyways i scored these crager style wheels of craigslist for 60 bucks. I thought it would look good on the the b2200 but now trying to figure out what size tires to run. Any recommendations?
