As long as the overall size of the new tires is about the same, and the new rims have about the same offset, I can't see any gotchas.

If you were going to smaller rims, I might be concerned about brake caliper clearance. But going up won't pose any issues in that regard.

If the new tires have approximately the same height, I can't foresee any issue there. The offset is the only concern. If the new wheels result in the tires being more inboard, or more outboard, there could be a rubbing issue, usually while steering, or going over bumps.

If you can measure the offset of the new wheels, you can compare it to the existing ones to see how much difference there is, if any.



[Edit] Re-reading the thread title, if the 18" wheels came off an Impala, I wouldn't be worried at all. Just make sure you get the same size tires as came on that car.

If your socket set is all the same brand, you might be a city slicker.
