Will a 26x10.5 clear with stock backspacing?

[Timberwolf]

I have a set of 26x10.50-16 et streets from a former car still hanging around the house in good shape. I as htinking of picking up a cheap set of wheels for them. Maybe some black "Ultra 42" wheels. If I get a 16 x 8, what backspacing should I use to make sure the tires clear everything?

If they are et STREETS then there are probably actually 9" wide tires. I would think that either 3.5" - 4" back space should work.
