The 2014 GMC Sierra is equipped with P255/70R17 tires as the standard option. Don't be intimidated by the numbers - each one has a simple meaning. The first number, 255, represents the tread width in millimeters. The second number, 70, indicates the sidewall height in millimeters. Lastly, the third number, 17, denotes the wheel diameter in inches. Essentially, your truck is outfitted with 17-inch wheels. GMC suggests inflating each tire to 35psi for optimal performance. Proper tire inflation enhances braking effectiveness and extends tire lifespan. Over or underinflated tires wear unevenly and may require premature replacement.

I think that the second number, 70, represents 70% of the first number. Therefore, in this scenario, we have a width of 255 milliliters and a width of 178.5 milliliters (which is 70% of 255) on a 17-inch wheel.
