265/35R21 tires

265/35R21 is a 21-inch performance size on electric cars: tiresize.com lists it on the Tesla Model S with 21-inch wheels in both the 2012 to 2020 staggered fitment and the 2021-on cars, and on the Porsche Taycan and Audi e-tron GT with 21-inch wheels. Below are real prices for 58 tires in stock, three picks from budget UHP to summer, and what heavy EVs do to tires with a 3.6-inch sidewall.

What 265/35R21 tires cost

Prices are per tire, before mounting and balancing. A set of four in the mid range comes to roughly $1,315 to $1,788, and a brand rebate can take another $50 to $110 off, see this month's deals.

Heavy, fast cars on very short sidewalls

A Model S or Taycan is heavy and accelerates hard, and on 21-inch wheels the tire has a sidewall of only about 3.6 inches. The result is quick wear, especially on the driven axle, and a firm ride, so warranty and price per mile matter more than usual.

All three picks are extra-load 101 tires, the index the size calls for on these cars. The speed rating differs: the Milestar and the Yokohama are Y-rated (186 mph), the Goodyear V-rated (149 mph). Compare the letter with your placard before ordering the Goodyear.

EV tires, foam and staggered sets

Electric cars are quiet, and tire noise becomes the dominant sound in the cabin. Some tires built for EVs have foam inside the tread to absorb cavity noise, and a replacement without it can sound louder. The picks here are conventional tires; if noise bothers you, look for a model marked as built for EVs or noise-reduced.

On staggered fitments, where the front and rear sizes differ, replace in axle pairs and keep front and rear on the same tire model.

What the numbers on the sidewall mean

A 265/35R21 tire is 265 millimeters wide, its sidewall is 35 percent of that (about 3.7 inches tall), and it mounts on a 21-inch wheel. That works out to an overall diameter of roughly 28.3 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 101V on the Goodyear Eagle Sport All-Season (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.

The Yokohama Advan Sport V107, our mid-range pick here at $327.99, is also stocked in 275/45R21 ($339.96), 285/40R22 ($519.20), 285/45R20 ($1,655.96) and 315/35R22 ($678.99).

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.

Frequently asked questions

How much do 265/35R21 tires cost?

Expect $121–$329 per tire for a budget brand, $329–$447 for a mid-range tire like the Yokohama Advan Sport V107, and $447–$653 for a premium tire like the Goodyear Eagle Sport All-Season. A set of four therefore starts at about $484. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 265/35R21 tires?

265/35R21 is original equipment on Tesla Model S (2012-2020, 21 in rear), Porsche Taycan (2020-2024, 21 in front), Audi e-tron GT (2022-2024, 21 in front) and Tesla Model S (2021-2024, 21 in Arachnid 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 265/35R21 tire?

For most drivers our mid-range pick, the Yokohama Advan Sport V107, 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 Goodyear Eagle Sport All-Season is worth the extra. On a tight budget the Milestar Interceptor AS810 is a sound choice.

Can I replace just one or two 265/35R21 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.
