As you can see from the pics this wheel and tire combo can be done!**
How wide can you go on a 10 inch rim?
A 285 is technically the “perfect” size for a 10 inch wide rim. You could go to 295, but you lose some of the structural support provided by the rim to the tire. That said, some tires also run a little more narrow than others, despite their size (Nittos come to mind).
What does 20×10 10 mean for tires?
The numbers 20-10-10 represent the dimensions of the tire. The first number is the height, the second number is the width & the third number is the diameter of rim that it will fit on.
What is wheel offset?
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types (measured in millimeters).* “The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel.”
