need wheel help

i'm sellin the reverse offset smoothies i bought and i'm buyin brand new ones from summit. they offer 15x6 with 3.75 backspacing with a +6mm offset. the 15x7 have a 4 backspacing with a 0mm offset. will these both tuck?

15x6's


15x7's

the 15x7 with 4" backspacing and 0 offset would be a no.

the 15x6 and the 3.75 is probably a no also.

I think v8 said the recommended backspacing is right at 5 3/4"

You should be able to get the 15x6's to fit. They stick out 1/4" more than Denali/Escalade 17's, but 1/4" less than QX56 wheels.

honestly i don't think either one of those wheels will tuck. like slammed 83 said the 0 offset wheels won't for sure.
as for the backspacing being 5 3/4 to tuck... depends on the width of the wheel...
that means there's 2 1/4" sticking out toward the fender from the wheel mount surface... determine if you have that much room (dont forget to account for tire bulge) between the inside of the fender and the wheel mount surface.
