does anyone know the actual heigth diffrence between a 16 wheel with a 180/65/16 and a 18 wheel with a 180/50/18. trying to decide what wheel to get for rear dont want it any taller but the 18s are easier to get in the wheels i want. thanks in advance

 

The 180/50/18 tire would be .12" shorter. They would both be 7.09 wide. You would be going from a 25.21" height, to a 25.09" height. You wouldn't notice it by looking.
