I'm looking to widen my Blazer's stance a bit. I want the tires flush with or sticking out a bit from the fenders. I'm not lifting it or anything so nothing too crazy. I'm just planning to swap out the 15x7 rims and install 15x8's. I believe the stock backspacing is 4". So can I simply buy 15x8's with the same backspacing and everything? Or will I have to mess with that as well? Sorry for the lack of knowledge I just can't seem to find enough useful information, and all the tire conversions are confusing the hell out of me on top of that.

 

if you go with the same backspacing then the wheels will be in the same location.
for the rear you can get wheel adapters off ebay to bring them out ...3/4" i think will do it.

 

So would I go with a larger or smaller backspacing? I don't want to start messing with wheel spacers or anything like that.

 

i "believe" smaller number equals tire out further.
i mentioned wheel spacers because the rear wheels set in further then the front in a stock setup. i did it to equal them out.
also i think if you stick with stock backspacing and a wider wheel you will have rub issues.
if you do a search on backspacing you will find lots of answers that will help.

 

stock rims are approx 6 in of backspace

and wart is right about needing spacers on the rear if you want to even out the stance

 

Yeah I think if you have a 4x4 stock backspacing is 6" if you have 2wd stock backspacing is 4" and the lower the number of backspacing the farther it'll stick out. I have 4 or 4.5" backspacing on my 98 4x4 and they stick out a good inch-inch and a half it looks really good

 

yah 98

I forgot about the 2 wheel blazer's backspace

but I didn't know what blazer he was working on

 

me either, thats why i thought id help out and put both just in case haha

 

98
understand bro

 

This is interesting, I have stock susp. So if I can make the rears come out even with the fronts on my 2000 LT 4x4, what spacer number would I need? I plan on giving it a lift later, but I intend let the rim do the rest of the spacing there. Kinda like the iroc's do for wart's blazer, then just add some flares to it.
