275/35R21 tires

275/35R21 is the rear tire of the Tesla Model Y on 21-inch wheels, paired with 255/35R21 in front. It is a large, extra-load, high-speed size that only a few cars use, so the choice is narrower and prices are higher than in the Model Y's 19- and 20-inch sizes. Below are real prices for 58 tires in stock, three picks with their size-specific specifications, and what to expect from a staggered 21-inch setup.

What 275/35R21 tires cost

Prices are per tire, before mounting and balancing. A set of four in the mid range comes to roughly $1,424 to $2,299, and a brand rebate can take another $50 to $110 off, see this month's deals.

Buying the rear pair of a staggered set

Because the front and rear sizes differ, the tires cannot be rotated front to rear, and on a rear-biased, high-torque EV the rears usually wear out first. That makes this a size you often buy as a pair, and it is worth matching the model of the fronts so the car's grip stays balanced. If the fronts are still good and the same model is unavailable, choose a replacement with the same speed rating and a similar treadwear grade.

The low 35-series sidewall gives little protection against potholes, and sidewall damage cannot be repaired. Check pressures monthly; the car's monitoring system warns only after a significant drop.

Quiet tires for a loud size

Big, wide wheels generate more road noise, and in an EV there is nothing to cover it. Our mid pick is Hankook's all-season for electric SUVs, which uses a knurled tread surface to cut pattern noise and is designed for range as well as grip. The budget pick is a performance tire its maker says should not be used when temperatures stay below 45 degrees Fahrenheit, which makes it a Sun Belt choice only.

What the numbers on the sidewall mean

A 275/35R21 tire is 275 millimeters wide, its sidewall is 35 percent of that (about 3.8 inches tall), and it mounts on a 21-inch wheel. That works out to an overall diameter of roughly 28.6 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 103W on the Hankook iON evo AS SUV (1,929 lb per tire, rated to 168 mph) and 103V on the Pirelli Cinturato P7 All Season (1,929 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.

Lexani LX-Twenty. The lowest-priced tire in this size by far, an extra-load 103Y graded 320 A A, at 36 pounds the heaviest of the three. Its maker rules it out for cold weather, and a 320 treadwear grade on a heavy EV's rear axle means short life.

Hankook iON evo AS, $488.99. In this size the retailer stocks Hankook's SUV version of its EV all-season, designed for electric SUVs, with noise-reducing tread technology. It is an XL 103W graded 600 A A, the best treadwear here, with a 50,000-mile warranty.

Pirelli Cinturato P7, $591.35. Pirelli's grand-touring all-season, an XL 103V in this size with 10/32 inch of tread and a 500 A A grade. The line includes run-flat and noise-cancelling versions in some sizes; check the listing for which one you are getting. The size comes without a mileage warranty.

What 275/35R21 tires cost across the whole range

Of the 64 tires listed in this size, 58 are in stock today. The lowest price is the Lionhart LH-Five UHP All Season at $136.07, a 103Y tire. The median is $488.99; a third of the tires cost $355.99 or less, and the top five percent start above $643.55. 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 Hankook iON evo AS SUV, our mid-range pick here at $488.99, is also stocked in 255/35R21 ($253.99), 285/45R21 ($472.99), 255/40R20 ($413.99) and 265/35R22 ($425.99). 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.

Vehicles that came with 275/35R21

• Tesla Model Y Performance (2020-2024, 21 in rear)
• Bentley Continental GT (2019-2024, 21 in front)
• Lexus LC 500 (2018-2024, 21 in rear)

We confirmed this size as the 21-inch rear fitment of the Model Y; for the other cars listed here, read the placard, since several use it only on one axle or not at all.

Frequently asked questions

How much do 275/35R21 tires cost?

Expect $136–$356 per tire for a budget brand, $356–$575 for a mid-range tire like the Hankook iON evo AS SUV, and $575–$644 for a premium tire like the Pirelli Cinturato P7 All Season. A set of four therefore starts at about $544. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 275/35R21 tires?

275/35R21 is original equipment on Tesla Model Y Performance (2020-2024, 21 in rear), Bentley Continental GT (2019-2024, 21 in front) and Lexus LC 500 (2018-2024, 21 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 275/35R21 tire?

For most drivers our mid-range pick, the Hankook iON evo AS SUV, 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 Cinturato P7 All Season is worth the extra. On a tight budget the Lexani LX-Twenty is a sound choice.

Can I replace just one or two 275/35R21 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.
