Cragars + Tires Combo

I'm looking at getting some Cragars all around, and new tires to match.
I'm thinking of going with 16x7s in the front and 16x8 in the rear.
Now I am no expert at tires, and am guessing that I can take them to our local tire place and they'll put the correct size on all four. I wonder if the Cragars will fit okay with no modifications; again, I am un-knowledgeable when it comes to tires so any help will be greatly appreciated.

Thanks

 

Cragers fit fine. Just get the right back spacing and what-not

 

Anybody know about what backspacing I should use?
I was thinking four, but again, I have no idea.

 

i think 4.25 is ideal, 4 should work well too

 

I got mine and just installed them. They needed offset washers and shanked lugnuts. They came with Kelly Charger 225/75 R15s already on them but the front scrubbed bad so I had 195/65 R15s put on the front pair.
