Upsizing or downsizing tires may be a great way to modify the appearance of your ride...
However, it may have an effect on their overall performance.
Because your tire spins fewer revolutions per mile when you switch to a higher tire, your speedometer will typically read slower than you seem to be actually travelling. As mentioned by xmudderwheel You may also notice increased road noise or a change in the way your car behaves. Lowering the profile of your automobile or truck by utilizing smaller tires can change both the handling and the amount of clearance you have; you may have difficulty driving over hills you could previously clear.
