82 GMC Sierra wheels and tires..

[fastnloud]

Hey guys, I'm new here. I've got an 82 GMC Sierra with a built 350 I'm working on. Wheels and tires, and lowering is next on my list.

I'm going to be lowering it 4/5 and I'm looking to put black 15 inch wheels on it, and the biggest tires I can fit on the rear.

I was originally going to go with 15x8 in front and 15x10 in rear with a 5 inch backspacing in the rear, but I'm not finding many 15x10 wheels with a 5 inch backspacing.

So, I think I may just do 15x8 all the way around. I'm looking at getting Cragar soft 8s.

If I get a 15x8 with a 4 inch backspacing and Mickey Thompson 30x12.50x15 tires , will it tuck ok in the rear?

I'm gonna run smaller tires up front, what backspacing should I go with on the 15x8 front wheels?
