255/45R20 tires
255/45R20 is a 20-inch size shared by electric and conventional crossovers. It is the front tire on the 2016 to 2020 Tesla Model X with 20-inch wheels, the 20-inch size on the Kia EV6 GT-Line and the Nissan Ariya, and the size on the 2022 to 2024 Mitsubishi Outlander SEL. Below are real prices for 227 tires in stock, three picks that include an all-weather option, and what changes when the car is an EV.
Yes, this fits your Infiniti QX50. 255/45R20 is the original size on the 2019-2024 Infiniti QX50.
The sticker inside the driver's door is still the final word, because trim and wheel package can change the size. Back to every Infiniti QX50 size.

Heavy, quiet and quick: what EVs ask of this size
An EV crossover in this size weighs several hundred pounds more than a gas crossover of the same footprint, and its motor delivers full torque instantly. Both wear the tread faster, especially on the driven axle, so the treadwear grade and the load rating deserve more attention than on the Outlander. All three of our picks are extra-load 105 tires in this size, rated for 2,039 pounds each.
Noise is the other issue. Without an engine to cover it, tire roar is the loudest sound in an EV cabin, and some replacement lines add a foam layer inside the tread for that reason. If your car came with foam-lined tires, a plain replacement will sound louder; that is normal, not a defect.
Model X: buying the front pair of a staggered set
The Model X runs a wider tire on the rear axle, so 255/45R20 is only half of the order. Buy the same model front and rear so the grip is balanced, and if you replace only the fronts, match the new tread depth as closely as possible to what is left on the rears; all-wheel-drive systems compare wheel speeds, and a large difference in diameter between axles makes them work harder. Staggered sets cannot be rotated front to rear, so expect the two axles to wear out at different times.
What the numbers on the sidewall mean
A 255/45R20 tire is 255 millimeters wide, its sidewall is 45 percent of that (about 4.5 inches tall), and it mounts on a 20-inch wheel. That works out to an overall diameter of roughly 29 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 105W on the Kumho Ecsta PA51 (2,039 lb per tire, rated to 168 mph), 105V on the Hankook Weatherflex GT (H755A) (2,039 lb per tire, rated to 149 mph) and 101V on the Bridgestone Alenza Sport A/S (1,819 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.
| Kumho Ecsta PA51 | Hankook Weatherflex GT (H755A) | Bridgestone Alenza Sport A/S | |
|---|---|---|---|
| Price per tire (Nov 13, 2026) | $281.96 | $241.99 | $367.40 |
| Set of four | $1,127.84 | $967.96 | $1,469.60 |
| Service description in 255/45R20 | 105W | 105V | 101V |
| Mileage warranty | 45,000 mi on non-OE tires | see listing | 40,000 mi |
| UTQG treadwear / traction / temperature | 500 AA A (typical, varies by size) | see listing | see the retailer's listing |
| Season | Ultra-high-performance all-season | see listing | Ultra-high-performance all-season |
| Extras | — | — | — |
Kumho Ecsta PA51, $281.96. Kumho's ultra-high-performance all-season, in an XL 105W construction with 11/32 inch of tread. It is graded 500 AA A and backed by 45,000 miles of warranty on non-OE tires. A sporty choice for the EV6 GT-Line.
Hankook Weatherflex GT (H755A), $241.99. The tire we would pick for an EV in the snow belt: an all-weather tire with the three-peak mountain snowflake symbol, so it is rated for severe snow, yet warranted for 70,000 miles and graded 720 A A in this size. One set for the whole year, without a seasonal swap.
Bridgestone Alenza, $367.40. Bridgestone's sport all-season for SUVs, original equipment on the current BMW X5 and X7. In this size the retailer stocks it as an XL 105T, and a T speed rating is lower than many 20-inch fitments call for; check your placard. No mileage figure is listed for it in this size.
What 255/45R20 tires cost across the whole range
Of the 263 tires listed in this size, 227 are in stock today. The median is $253.70; a third of the tires cost $195.99 or less, and the top five percent start above $486.17. 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 Kumho Ecsta PA51, our budget pick here at $281.96, is also stocked in 245/40R20 ($161.92), 245/45R20 ($262.08), 225/45R19 ($235.96) and 245/35R19 ($215.97). 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. Prices per tire, from the retailer's feed Nov 13, 2026.
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 Kumho Ecsta PA51 and Bridgestone Alenza Sport A/S, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions
How much do 255/45R20 tires cost?
Expect $114–$196 per tire for a budget brand, $196–$315 for a mid-range tire like the Hankook Weatherflex GT (H755A), and $315–$486 for a premium tire like the Bridgestone Alenza Sport A/S. A set of four therefore starts at about $456. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 255/45R20 tires?
255/45R20 is original equipment on Tesla Model X (2016-2024, 20 in front), Hyundai Ioniq 5 (2022-2024, Limited 20 in), Kia EV6 (2022-2024, GT-Line 20 in), Nissan Ariya (2023-2024, 20 in), Infiniti QX50 (2019-2024, Sensory 20 in), Mitsubishi Outlander (2022-2024, SEL 20 in), Volkswagen ID.4 (2021-2024, 20 in Pro S rear) and Rolls-Royce Ghost (2010-2020, 20 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 255/45R20 tire?
For most drivers our mid-range pick, the Hankook Weatherflex GT (H755A), 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 Bridgestone Alenza Sport A/S is worth the extra. On a tight budget the Kumho Ecsta PA51 is a sound choice.
Can I replace just one or two 255/45R20 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.
