What are the offset on my wheels?

Hey I have these fuel krank wheels on my taco but am looking to get new ones… the thing is I forget what specs they are. They are either a +1 offset or -12… I’m kinda new so I’m not sure how to tell. Any help appreciated

 

Google?

 

My guess would be they are +1 but they also show a +20 on their website.

 

should be stamped on the backside of the rim.

 

Negative numbers push your tires outward (more exposed) while positive numbers suck your tires inward. From the looks of it you have the -12 since your wheels/tires are sticking out from where the stock wheels would be.

 

It depends on the width of the rim as much as the offset if they will stick out much. Here's my old truck with 17x8.5 with -10 offset and they stick out farther than his wheels which are 17x9. Tire width also makes a difference in how much it might poke out.
