what offset and backspacing?

[oliva507]

I have a 2012 ram 1500 with rcx 4 inch lift being installed. My question is what offset and backspacing do i need for a 20 inch wheel with 35x12.5/20. Ihave the tires just need help understanding what this means. Thanks

Depends on how far you want them sticking out. 0 offset with 4.5 inch backspacing will line ya right up if you have stock fender flares, any - number will make ya stick out even more,

Well then why are they only giving me the choice of-12 or-24 offset and no backspacing choice?

Well what wheels are you looking at?? the -12 would work really well, except you will probably want to get some fender flares if you don't already have some

They are the fuel kranks. And no I don't have flares...yet

Unless you have a 2500 hemi then the fuel cranks come in 1 and 14 offset

1 offset would be perfect, thats what i have on my 35's and i love em
