Model 3 on 18-inch Aero wheels

The Model 3 is a heavy car for its size, it is very quiet inside, and it delivers full torque from a standstill. All three facts show up in the tires. Weight and torque wear the tread faster than on a Camry of the same size, so treadwear grades matter. With no engine noise to mask it, road roar from an ordinary tire is easy to hear, which is why many replacement tires for EVs have a foam liner inside the casing. And because rolling resistance takes a direct bite out of range, a fuel-saving touring tire gives back more miles than it would on a gas car.

If your Model 3 is a long-range car you drive on the highway, choose for low noise and low rolling resistance. If you drive it hard, an ultra-high-performance all-season with an XL rating is the better match.

Touring or ultra-high-performance all-season

The sedans in this size split into comfort trims and sport trims, and the tires split the same way. A grand-touring tire rides softer, lasts longer and is quieter; an ultra-high-performance all-season steers more sharply and grips harder, but usually wears faster. In this size the Continental pick is a UHP tire rated 98Y XL, and the Bridgestone is a softer 94V tire with a 55,000-mile warranty. Either is a step up from a budget tire on a car with this much power.

What the numbers on the sidewall mean

A 235/45R18 tire is 235 millimeters wide, its sidewall is 45 percent of that (about 4.2 inches tall), and it mounts on a 18-inch wheel. That works out to an overall diameter of roughly 26.3 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 94V on the Bridgestone Potenza RE97AS (1,477 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.

Westlake SA07 Sport. A low-cost all-season for performance-styled sedans, warranted for 45,000 miles and without the 3PMSF symbol. The retailer is not stocking it in 235/45R18 today, so the price box shows the alternatives.

Continental ExtremeContact DWS06 Plus, $200.99. Continental's ultra-high-performance all-season, the sharpest-handling tire here. In 235/45R18 it is an extra-load 98Y, graded 560 AA A, with a 50,000-mile warranty (25,000 on staggered fitments). Our pick for a Camry XSE driver who likes to drive, or a Model 3 that is driven briskly.

Bridgestone Potenza RE97AS, $244.49. Bridgestone's all-season performance tire, with a casing designed to lower rolling resistance for better mileage. In this size it is a standard-load 94V with 10/32 inch of tread and a 55,000-mile warranty in V-rated sizes. The treadwear grade of 400 is the lowest of the three.

What 235/45R18 tires cost across the whole range

Of the 336 tires listed in this size, 263 are in stock today. The median is $180.96; a third of the tires cost $125.99 or less, and the top five percent start above $291.99. 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 Continental ExtremeContact DWS06 Plus, our mid-range pick here at $200.99, is also stocked in 235/40R19 ($241.99), 225/45R18 ($196.99), 215/45R18 ($189.99) and 225/40R18 ($168.99). 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 a sedan in this size

Most sedans in this size are front-wheel drive, and that decides what the snow laws ask of the tires. On the 126 miles of I-70 between Dotsero and Morrison, Colorado's Passenger Vehicle Traction Law runs from September 1 to May 31: a two-wheel-drive car needs tires marked M+S, 3PMSF or rated all-weather by the manufacturer, with at least 3/16 inch of tread, and fines start at $130. The touring all-seasons that dominate this size are almost all M+S rated. An all-wheel-drive sedan passes on the vehicle alone, but all-wheel drive only helps you accelerate; braking and cornering on snow come entirely from the tire, so an all-weather tire with the 3PMSF symbol is the better year-round answer in the snow belt.

None of our picks in this size, the Continental ExtremeContact DWS06 Plus, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions

How much do 235/45R18 tires cost?

Expect $78–$126 per tire for a budget brand, $126–$206 for a mid-range tire like the Continental ExtremeContact DWS06 Plus, and $206–$292 for a premium tire like the Bridgestone Potenza RE97AS. A set of four therefore starts at about $312. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 235/45R18 tires?

235/45R18 is original equipment on Toyota Camry (2018-2024, SE), Honda Accord (2013-2017, EX-L V6/Touring), Ford Fusion (2013-2020, Titanium), Tesla Model 3 (2017-2023, 18 in Aero), Kia K5 (2021-2024, GT-Line), Hyundai Sonata (2020-2024, SEL Plus/N Line), Kia Soul (2014-2019, Exclaim) and Volvo S60 (2019-2024, 18 in), 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 235/45R18 tire?

For most drivers our mid-range pick, the Continental ExtremeContact DWS06 Plus, 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 Potenza RE97AS is worth the extra. On a tight budget the Westlake SA07 Sport is a sound choice.

Can I replace just one or two 235/45R18 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.
