Will this wheel size work?

[progress1vebmx]

15x8.5 (front); 15x10 (rear) 3.5" backspacing. I went to the Centerline website and looked at their overstock wheels. The HT Convo Casts looked pretty good and I can't really spend a lot of money. Will these wheels work without a lot of trouble? What size tires would be best with these?

Instead of going out and getting these, should I just go ahead and get something else...?
