Frequently Asked Questions
The standard cold inflation pressure for a 245/55R19 tire is 30-35 PSI. However, the ideal tire pressure varies slightly depending on tire type and your vehicle’s specifications. The best source for your specific make and model’s PSI is the placard at the driver’s doorframe or your vehicle’s owner’s manual.
This is the tire size information. 245 is the tread width measured in millimeters. 55 is the ratio in percent of the sidewall’s height to the width of the tread. “R” is an abbreviation for radial construction, and 19 is the wheel diameter in inches.
This tire size, once properly mounted and inflated on a 19-inch wheel, has an overall width of about 28.3 inches. A 9.6-inch tread face and a 6.6-inch sidewall height are included in this, which is broad and high. This kind of tire is has a larger 55% aspect ratio.
The most closely matching dimensional equivalents are 255/50R19, 235/60R19, or 235/55R19. These variations are close in general diameter and tread width, and mounted tire sidewall height variations are only around an inch.
While most vehicle manufacturers recommend rotating 245/55R19 tires every 5,000 – 8,000 miles to achieve even tread wear on all four tires, the perfect rotation intervals may vary. Some of the factors that influence this include your driving style, alignment valuations and vehicle weight.
