I have a 03 4x4 2 dr Blazer LS. I'd like to put a set of Weld Pro Stars on it. These are the specs of the ones I'm looking at. 15x7, 5.5 inch backspace and 38.00 mm offset. I'm also thinking of running 30 inch tires. What you think?

 

sounds like a plan. Post up some pics.

 

So you don't think I'll have many problems with the wheels I described?

 

It sounds like those should work perfect, they will stick out about a half inch more than stock and then with the 30x9.5" tires you will have about a .5"-1" wider tread pattern IIRC. So it should fit in there no problems with the stock suspension setup. Otherwise you could crank the torsion bars about a half inch if you need just a litte bit more clearance. But I think the 30" tires should work fine.
