Using a steel ruler, measure from the top of a fork tube or cap to the top of a clip-on or the triple clamp. If the new front tire is taller than the old, the front of the bike needs to be lowered to keep the chassis at the same attitude. Ideally, you would change your rear ride height to account for rear tire changes, but since most bikes don't have that adjustment you can take into account a change in rear tires at the same time. If you do have a rear ride height adjuster on your bike, you can accommodate the front and rear changes individually.
