275/40R20 tires

275/40R20 is the Hellcat size: the Dodge Charger SRT Hellcat from 2015 to 2023 and the Challenger SRT Hellcat of 2015 to 2018 run it, and tiresize.com lists it on the Charger Scat Pack as well. It is the rear tire on the Lexus LS 500 F Sport and the size on the 2012 to 2018 Bentley Continental GT with 20-inch wheels. Below are real prices for 175 tires in stock and three picks from budget all-season to summer.

Putting a supercharged V8 on the road

A Hellcat sends a supercharged V8's output to the rear wheels alone, and the tire's job is to turn that into motion. A summer tire does it best in warm weather; an ultra-high-performance all-season trades some grip for usable traction in the cold. Our mid-range pick, the Hankook Ventus S1 evo2 SUV, is a summer tire per the retailer, and the Pirelli and the Atturo are all-seasons.

All three picks are 106Y extra-load tires, rated to 186 mph and 2,094 pounds. That load index is what the size calls for on these heavy cars; a lower one would not meet the placard.

Rear tires wear first

On a rear-drive Charger or Challenger, the rear tires wear much faster than the fronts, especially with launches. Where the fitment is square, with the same size at both ends, rotate front to rear on schedule. On the LS 500 F Sport this is the rear size of a staggered set, so it cannot be rotated, and the rears will need replacing first.

BMW X5 owners should check their placard: tiresize.com lists the 2014 to 2018 X5 on 255/55R18 and 255/50R19 in the standard trims, and we could not confirm this size as a factory fitment for it.

What the numbers on the sidewall mean

A 275/40R20 tire is 275 millimeters wide, its sidewall is 40 percent of that (about 4.3 inches tall), and it mounts on a 20-inch wheel. That works out to an overall diameter of roughly 28.7 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 106Y on the Atturo AZ850 and Pirelli P Zero All Season Plus (2,094 lb per tire, rated to 186 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.

Atturo AZ850, $328. An ultra-high-performance all-season designed, per the retailer, for CUVs, SUVs and light trucks, listed as 106Y in this size, with a 320 A A treadwear grade in a representative size and no mileage warranty per the retailer. A budget option for a Hellcat that is driven rather than raced.

Hankook Ventus S1 evo2 SUV (K117A), $306.99. A summer tire designed for warm weather, with an alignment indicator in the tread and a 220 AA A treadwear grade in a representative size. No mileage warranty is published. It is listed as and is the grip pick of the three in summer.

Pirelli P Zero All Season Plus, $308.99. The listing here is Pirelli's P Zero All Season Plus, an ultra-high-performance all-season with a 50,000-mile warranty and a 30-day trial on sets of four, per the retailer. It is listed as 106Y and suits a Hellcat driven year-round.

What 275/40R20 tires cost across the whole range

Of the 219 tires listed in this size, 175 are in stock today. The median is $216.06; a third of the tires cost $143.96 or less, and the top five percent start above $440. 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 Atturo AZ850, our budget pick here at $328, is also stocked in 285/30R20 ($146.96), 285/35R20 ($155.96), 295/45R20 ($185.96) and 245/55R19 ($131.96). The Pirelli P Zero All Season Plus, our premium pick here at $308.99, is also stocked in 215/45R18 ($187.98). 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 Atturo AZ850, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions

How much do 275/40R20 tires cost?

Expect $106–$144 per tire for a budget brand, $144–$276 for a mid-range tire like the Hankook Ventus S1 evo2 SUV (K117A), and $276–$440 for a premium tire like the Pirelli P Zero All Season Plus. A set of four therefore starts at about $424. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 275/40R20 tires?

275/40R20 is original equipment on Dodge Charger SRT Hellcat (2015-2023), Dodge Challenger SRT Hellcat (2015-2018, 20 in), Dodge Charger Scat Pack (2019-2023), Bentley Continental GT (2012-2018, 20 in), BMW X6 (2015-2019, 20 in non-M front), Lexus LS 500 F Sport (2018-2024, 20 in rear) and Lexus LC 500 (2018-2024, 20 in rear), 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 275/40R20 tire?

For most drivers our mid-range pick, the Hankook Ventus S1 evo2 SUV (K117A), 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 Pirelli P Zero All Season Plus is worth the extra. On a tight budget the Atturo AZ850 is a sound choice.

Can I replace just one or two 275/40R20 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.
