Wheel Offset Question

Hello, I drive a 2024 Tundra Limited Hybrid TRD Offroad.

I have found some wheels that I am planning on purchasing for my Summer/All Season tires.

There are 2 different providers that sell the wheels a this time. One place is offering them in an 18 offset, the other is a 20 offset. I am not looking for anything too aggressive, and I don't understand the offset system very well even with doing a bit of reading into it. But I would think the 20 offset would stick out less, if I am understanding it correctly?

I wanted to know firstly if 18 to 20 offset is much difference? and secondly how much each is likely to stick out, as I don't want much sticking out of possible, a slight amount is fine but I am worried about paint damage.

The provider selling the 20 offset wont be available until late March, when I can purchase the 18 offset at this time, and I am leaning towards not waiting if the difference wont matter.

Thank you for your help
Have a nice day.

 

Not much difference, both more poke than stock, which is 50-60 depending on wheel.

 

Here is a great tool to help understand difference in fitment with offset changes

 

18 and 20 are mm measurements so a 2mm difference would hardly be noticeable. Offset is the distance from the centerline of the wheel to it's rear mounting surface. So a rim that is 8" wide has a centerline of 4" +18mm offset means the mounting surface on that rim is 18mm (or .7") further away (outside) from the from the centerline of the rim. 18mm would stick out "poke"(wheel protrusion outside wheel well) a little less than 20mm. For future refrence, the more positive the number, the less poke. Deep dish rims generally are negative offset rims
