Please Help With Backspacing?

[jwpotts0413]

could someone plz school me on backspacing and how to determine it for custom wheels?

 

i am trying to figure out what is the fattest tire/wheel combo for my truck that will fit w/o too much rub. it's a 2 wheel drive short box regular cab 2004 silverado w/ 4.8L v8 & 5speed trans.

 

i'll be going with something similar to these American Racing 767s:

 

 

wrapped with some thing like 50 or 55 profile BFGoodrich Radial T/A tires

 

 

all advice is appreciated, i'm going for a NASCAR cup car wheel/tire look. truck is stock height, what size wheels/tires do i need? i was thinking maybe 15x8 with 295/50/15 tires? anyone who has done this please offer up your sizes. what rubs/doesn't rub, etc...

 

 

thanks in advance

I wouldn't go with any wheel wider than 9.5" with 6.12" backspacing if you are going with 295 or 305 tires.

thx jennabear, i'll be going with 295 tires, most likely. i like when the centercap is recessed back into the wheel, wouldn't i want like 3-4" of backspace to get that look?

 

also, does anyone know a wheel that looks just like the one in my original post, but doesn't have that goofy red & blue striped lip??

 

thanks in advance

15" wheel will NOT fit an 04 truck. You need to have a 16" rim min. The 15" rim will rub on your front brake caliper.

i just learned that from another forum. they said 2005+ can fit a 15" wheel, but 2004 i'll have to take a grinder to the front brake calipers which i'd rather not do. i am thinking 16x8 up front and 16x10 out back. anyone know what size tires i should buy to minimize rubbing??

 

also, regarding my earlier question about a plain black wheel of this pattern:

 

the Pacer Daytona is the same pattern but no goofy red & blue stripe. here's a pic:

 

 

and NASCAR themselves make a pretty slick looking wheel, but it's a good bit more expensive:

ok i figured it out, i can fit a 20mm offset with 6.10" backspacing and that will make a nice looking rim lip with minimal tire rub
