What 255/40R19 tires means
The 255/40R19 size code describes the tire's exact geometry. The 255 is the section width in millimeters (about 10.04 inches across the widest part of the tread). The 40 is the aspect ratio, meaning the sidewall height is 40% of the section width — that works out to roughly 102 mm (4.02 inches). The R stands for radial construction, and the 19 is the wheel diameter in inches this tire is built to mount on.
Add the sidewall on both sides to the 19-inch rim and the overall tire diameter comes to about 27.03 inches, turning roughly 746 revolutions per mile. Those numbers matter to you: the overall diameter determines speedometer accuracy and clearance in the wheel well, while the relatively short 40-series sidewall favors crisp steering response over a plush ride. Sticking to the exact 255/40R19 spec keeps your gauges honest and your handling predictable.
Vehicles & uses
255/40R19 is a low-profile size found in the ultra-high-performance and touring categories — the kind of tire commonly fitted to sport sedans, coupes and performance-oriented cars running 19-inch wheels. The wide tread and short sidewall are built for grip and steering precision rather than soft cushioning. Always confirm the size against your door-jamb placard or the sidewall of the tires already on your car before ordering.

How to choose
Season
Summer tires deliver the sharpest dry and wet grip in warm weather; all-season tires trade some peak grip for year-round usability and light-winter capability; dedicated winter tires are the choice for snow and ice. Match the season to your climate and how you drive.
Treadwear & UTQG
The UTQG rating (treadwear, traction and temperature) printed on a tire's sidewall helps you compare expected longevity and grip between models. A higher treadwear number generally suggests a longer-wearing compound, while performance tires often trade tread life for grip.
Load index & speed rating
The load index and speed rating (the number and letter following the size) tell you how much weight each tire can safely carry and the maximum speed it is rated for. Meet or exceed the ratings specified for your vehicle — never go below them.
Warranty
Many touring and all-season tires carry a mileage treadwear warranty, while summer performance tires often carry little or none. Check each product page for the details before you buy.
