Firestone Firehawk Indy 500
The value sweet spot: long mileage warranty, solid wet grip, sane price.

Michelin Pilot Sport 4S
Best wet and snow braking, quietest ride, longest tread life. Worth it if you keep the car.

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.
The numbers mean: 255 mm section width, sidewall height 40 % of that width, and a 19-inch rim. Overall diameter works out to about 27 inches. Any replacement has to match all three, and the load index and speed rating on your door sticker must be met or exceeded. Our guide on reading a tire size walks through it.

What is the best 255/40R19 tire?
For most drivers our mid-range pick, the Firestone Firehawk Indy 500, 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 Michelin Pilot Sport 4S 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.
