Default Offset Question

I'm shopping for 17x9 wheels that I want to wrap with 37x13.5 inch Mud Grapplers and need to know if I'm thinking right about the offset:

From reading on this forum I believe a 17x9 wheel needs -12 offset for my 4" lifted Rubi. According to Discount Tire this wheel (American Outlaw / Buckshot) comes in 5-127 bolt pattern but has a +15 offset. Would 1.5 inch (38 mm) spacers make it work?

Am I overlooking anything?

These wheels are 5.1" backspaced. You want around 4.5-4.7 inches of backspace. So half inch spacers will work better than anything. Don't know if they come in 1/2" but that's what I would use.

I cannot recommend a wheel as I am not knowledgeable on what size is okay for what lift but purely going with your dimensions for comparison purposes....

Option1: 17 x 9 with -12 offset equates to ~ 4.47" Backspace
Option2: 17 x 9 with a +15 offset equates to ~ 5.6 Backspace

You would need a ~ 1" spacer to go from option 1 to option 2 for the wheel/tire combo to be sitting in the same spot.

Good info, guys, thanks.

You answered my main concern... that spacers on a new wheel is NOT a bad idea. I was afraid they were only for bigger tires on stock wheels or just a bad idea in general.

Anyone else have an idea for the best solution for this wheel/tire combo? All opinions welcome and I promise pics when it all comes together.

Why buy an expensive wheel that you know has an incorrect backspace, and then buy spacers to correct? Keep looking until you find a wheel that you like with a correct BS.

There are plenty of threads on wheel spacer safety. The gist of it is that you want to use a set with quality hardware (grade 8 or better), and you want two sets of lugs. NOT the thin kind that sandwich in between. (ie, spidertrax type spacers). And you must be willing to MAINTAIN them!!

But again, why buy expensive wheels 'and' expensive spacers?

what if you already have spacers, and then you get expensive wheels? is there anything such as too much backspace? would 3.5" be okay?

I hear ya! I haven't decided definately on these but they are my current faves. But I damn sure wish these came in a -12 offset. As far as price goes it's the tires that eat you up not the wheels. $125ish per wheel but $425 per tire... x5! Whats another $200, right?

For me, the bigger concern would be that I buy from discount tire, they offer free balance and rotation for the life of the tire, and they won't touch a rig with spacers. And I'm lazy enough to not want to rotate/balance my own tires every 3k.
