255/45R19 tires

255/45R19 is the size on the Tesla Model Y with the 19-inch Gemini wheels, which makes it one of the fastest-growing sizes in the country. The same size is fitted to the 2010 to 2019 Ford Taurus SEL and Limited, the front axle of the Porsche Panamera on 19-inch wheels, and some Model S. Below are real prices for 140 tires in stock, three picks with very different priorities, and what Model Y owners should weigh.

What 255/45R19 tires cost

Prices are per tire, before mounting and balancing. A set of four in the mid range comes to roughly $964 to $1,304, and a brand rebate can take another $50 to $110 off, see this month's deals.

Model Y: noise, range and the 45-degree question

On a Model Y the tire is the loudest thing in the car. A foam insert inside the tread damps the cavity resonance you hear as a hum on coarse pavement, which is why EV-specific tires such as the Falken pick carry one. Rolling resistance comes straight off the range, and the EV's weight and instant torque wear the tread faster than on the Taurus that uses the same size.

One warning for owners in cold states: the Lexani budget pick is a performance tire that its maker says should not be used when temperatures stay below 45 degrees Fahrenheit. That rules it out as a year-round tire across the northern half of the country, however attractive the price.

Ford Taurus and Panamera owners

On a Taurus this is a comfortable, front- or all-wheel-drive sedan size, and a quiet touring all-season is the natural replacement; standard load is fine. On a Panamera it is the front size of a staggered set, with a wider tire behind it, so buy the front and rear as the same model to keep handling balanced, and look for tires carrying Porsche's N-marking if you want the version developed for the car.

What the numbers on the sidewall mean

A 255/45R19 tire is 255 millimeters wide, its sidewall is 45 percent of that (about 4.5 inches tall), and it mounts on a 19-inch wheel. That works out to an overall diameter of roughly 28 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 104Y on the Lexani LX-Twenty (1,984 lb per tire, rated to 186 mph) and 100H on the Continental ProContact RX (1,764 lb per tire, rated to 130 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.

Lexani LX-Twenty, $126.96. The cheapest way to fill this size, and a heavy, high-speed-rated tire at 29 pounds and 104Y. It is graded 320 A A, which predicts short tread life on a heavy EV, and its maker says it should not be used in consistently cold weather. Best for the Sun Belt.

Falken Azenis FK460 A/S Silent Core, $261. Built for electric cars: a foam layer inside the casing cuts cabin noise, and the XL 104W rating suits the Model Y's weight. Graded 500 A A with a 50,000-mile warranty. Our pick for most Model Y owners.

Continental ProContact RX, $264. A standard-load all-season with a 55,000-mile warranty and 9/32 inch of tread, popular with Tesla owners for its quiet ride. Read the load marking before you buy: in this size it is a 100H tire, while the Model Y placard calls for 104W XL, so it suits the Taurus better than the Tesla.

What 255/45R19 tires cost across the whole range

Of the 173 tires listed in this size, 140 are in stock today. The median is $278.65; a third of the tires cost $240.99 or less, and the top five percent start above $412.42. Those are per-tire prices before mounting and balancing, which adds $15 to $45 per tire at most shops, read from the retailer's feed Nov 13, 2026.

The same tires in neighboring sizes

The Lexani LX-Twenty, our budget pick here at $126.96, is also stocked in 285/40R19 ($151.08), 255/40R20 ($124.96), 225/35R19 ($96.96) and 225/40R19 ($96.96). The Continental ProContact RX, our premium pick here at $264, is also stocked in 285/40R19 ($379.06). 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 on an EV in this size

Electric vehicles are heavy for their size and deliver full torque instantly, which is exactly what loosens a tire on snow. Most EVs in this size are all-wheel drive and pass Colorado's Passenger Vehicle Traction Law on the 126 miles of I-70 between Dotsero and Morrison, in force from September 1 to May 31, on the vehicle alone, as long as the tires have at least 3/16 inch of tread; a rear-wheel-drive version needs tires marked M+S, 3PMSF or rated all-weather by the manufacturer. Fines start at $130. Whatever you fit, keep the load index at or above the door placard, since EV tires are usually XL rated for the battery weight, and expect any winter or all-weather tire to cost some range through higher rolling resistance.

None of our picks in this size, the Lexani LX-Twenty, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions

How much do 255/45R19 tires cost?

Expect $108–$241 per tire for a budget brand, $241–$326 for a mid-range tire like the Falken Azenis FK460 A/S Silent Core, and $326–$412 for a premium tire like the Continental ProContact RX. A set of four therefore starts at about $432. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 255/45R19 tires?

255/45R19 is original equipment on Tesla Model Y (2020-2024, 19 in Gemini), Ford Taurus (2010-2019, SEL/Limited), Porsche Panamera (2010-2016, 19 in front), Tesla Model S (2021-2024, 19 in Tempest front) and Mercedes-Benz S-Class (2021-2024, 19 in 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 255/45R19 tire?

For most drivers our mid-range pick, the Falken Azenis FK460 A/S Silent Core, 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 ProContact RX is worth the extra. On a tight budget the Lexani LX-Twenty is a sound choice.

Can I replace just one or two 255/45R19 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.
