28*9's or 28*10's

Will these fit on my car and on these rims?
Here are the details:
Running 12.5's with a 4.10 gear crossing the line at about 5900-6000 rpm using my 'worn out' 26" slicks which need to be replaced. With the addition of a few more bolt-on HP and 100 shot of n2o, I think I will be running out of rpm so 28" should be the right height. I am using the 3 spoke SN95 15" rims (five bolt but are the same offset and width as 10 holes) and am not sure how wide I can go for both the rim and for fender clearance. Car is lowered, no quad shocks, and fenders rolled, stock length axles.
