The offset is critical.

20x8 is not the issue they will fit the offset or bolt pattern is the question you need to ask, they have to match your vehicles bolt pattern or offset you have a 5 lug and rims come in different offsets of 5 lug so find out what yours are then find out what the rims you want to buy are.My 05 is 5x115 not sure about 07.

That's the lug pattern. Offset is the distance from the face of rotor (mounting surface) to the surface on which the tire bead seals.

Thanks always thought offset and bolt pattern were the same thanks for correction.

8 inch wide rims are a little narrow for 285mm width tires. My STS-V had 9.5 wide wheels for the stock 275mm tires.

Do you know the offset of the STS-V 9.5" wheels?

first off, no matter what 285s will not fit on a 20x8. no matter what. it will bubble around the rim if you put it on, and when you are taking a turn driving, the tire will unbead seal itself off the rim. kids now a days....
