About the 255/40R19 size
Mustang 19 in size, W/Y rated. Summer UHP dominates; the PP1 rear is 275/40R19 so check both axles.
What the numbers on the sidewall mean
A 255/40R19 tire is 255 millimeters wide, its sidewall is 40 percent of that (about 4.0 inches tall), and it mounts on a 19-inch wheel. That works out to an overall diameter of roughly 27 inches. Every replacement has to match all three numbers, and the load index and speed rating on the placard inside the driver's door have to be met or exceeded.
In this size our picks are marked 100W on the Kumho Ecsta PA51 (1,764 lb per tire, rated to 168 mph) and 100V on the Continental ContiProContact (1,764 lb per tire, rated to 149 mph). The first number is the load index, the letter the speed rating; a tire with equal or higher values than your placard is fine, a lower one is not.
Our guide on reading a tire size walks through the markings, and this one lists every load index and speed code.
Our three picks, side by side
One tire at each price level from what the retailer stocks in this size, with the mileage warranty and UTQG grades as published by the manufacturers and their retailers. Treadwear is the number to compare: it is a relative wear rate, so 700 should last roughly twice as long as 350 on the same car.

The same tires in neighboring sizes
The Kumho Ecsta PA51, our budget pick here at $233.06, is also stocked in 235/50R18 ($185.08), 225/45R19 ($235.96), 245/35R19 ($215.97) and 245/40R19 ($244.96). The Continental ContiProContact, our premium pick here at $293.17, is also stocked in 275/40R19 ($328.90), 225/60R18 ($174.96), 235/40R18 ($179.20) and 245/40R18 ($257.40). Useful if your vehicle came with a different wheel package, or if you are comparing an upsize: the same tire usually costs more per inch of wheel, not per inch of rubber.

Winter and this size: summer tires are not winter tires
Many tires sold in this size are summer tires, and the manufacturers advise against driving them in near-freezing temperatures: the compound hardens, grip drops sharply and the tread can crack. They also carry no M+S or 3PMSF marking, so a car on summer tires fails Colorado's Passenger Vehicle Traction Law outright on the 126 miles of I-70 between Dotsero and Morrison, in force from September 1 to May 31, unless it is all-wheel drive with at least 3/16 inch of tread; fines start at $130. If the car is driven year-round in a state with real winters, either run an all-season or all-weather tire in this size or keep a second set of winter tires, often on a smaller, narrower wheel that is also less expensive.
None of our picks in this size, the Kumho Ecsta PA51 and Continental ContiProContact, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions
How much do 255/40R19 tires cost?
Expect $93–$183 per tire for a budget brand, $183–$277 for a mid-range tire like the General G-MAX AS-07, and $277–$391 for a premium tire like the Continental ContiProContact. A set of four therefore starts at about $372. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 255/40R19 tires?
255/40R19 is original equipment on Ford Mustang (2024, EcoBoost Premium/GT), Chevrolet SS (2014-2017, upsize from 245/40R19) and Ford Mustang GT (2015-2023, 19 in Performance Pack front), among others. Always confirm with the sticker inside your driver's door, because trim levels and wheel packages can change the size.
What is the best 255/40R19 tire?
For most drivers our mid-range pick, the General G-MAX AS-07, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the Continental ContiProContact is worth the extra. On a tight budget the Kumho Ecsta PA51 is a sound choice.
Can I replace just one or two 255/40R19 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
