245/45R18 tires

245/45R18 is a large-sedan size.

Below are real prices for 261 tires in stock, three picks with their size-specific specifications, and what owners of European sedans should look for on the sidewall.

European sedans and manufacturer markings

German and British carmakers often approve specific versions of a tire for their cars, marked on the sidewall: a star for BMW, MO for Mercedes-Benz, AO for Audi. These tires share the tread pattern of the regular model but use a construction or compound tuned for that car. A non-marked tire in the right size is legal and fits; on an A6 or XF most owners will not feel a difference, but if you want the car to ride exactly as it did new, search for the marked version. Some of these cars also came on run-flats; check the sidewall of the tire you are replacing.

100 XL or 96 standard load

In this size the Milestar and Continental DWS06 Plus are extra-load 100-rated tires, and the Continental ProContact TX is a standard-load 96H. Either can be right: the requirement is the load index on your placard. Check the placard before choosing the 96, especially on the heavier executive sedans. The ProContact TX also uses a silica compound designed to lower rolling resistance, which is worth a little range on the hybrid versions of the MKZ.

What the numbers on the sidewall mean

A 245/45R18 tire is 245 millimeters wide, its sidewall is 45 percent of that (about 4.3 inches tall), and it mounts on a 18-inch wheel. That works out to an overall diameter of roughly 26.7 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 100V on the Milestar MS932 Sport (1,764 lb per tire, rated to 149 mph) and 96H on the Continental ProContact TX (1,565 lb per tire, rated to 130 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.

Milestar MS932 Sport, $118.99. A low-priced all-season in an extra-load 100V construction, graded 540 A A with 10/32 inch of tread and a 60,000-mile warranty for this V-rated size.

Continental ExtremeContact DWS06 Plus, $197.99. Our pick for a Maxima or Azera driven with intent: an XL 100Y ultra-high-performance all-season graded 560 AA A, with a 50,000-mile warranty and usable light-snow grip.

Continental ProContact TX, $210.96. Continental's touring all-season with a low-rolling-resistance silica compound, here a standard-load 96H with a 55,000-mile warranty (65,000 in S and T sizes) and 9/32 inch of tread. The quiet choice for an MKZ or A6.

What 245/45R18 tires cost across the whole range

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 245/45R18 tires cost?

Expect $75–$129 per tire for a budget brand, $129–$222 for a mid-range tire like the Continental ExtremeContact DWS06 Plus, and $222–$332 for a premium tire like the Continental ProContact TX. A set of four therefore starts at about $300. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 245/45R18 tires?

245/45R18 is original equipment on Nissan Maxima (2009-2014), Lincoln MKZ (2013-2020), Hyundai Azera (2012-2017), BMW 5 Series (2011-2016, base), Mercedes-Benz E-Class (2017-2023, base), Audi A6 (2012-2018, 18 in), Jaguar XF (2016-2020, base 18 in) and BMW 5 Series (2017-2024, 18 in M Sport style 662M 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 245/45R18 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 Continental ProContact TX is worth the extra. On a tight budget the Milestar MS932 Sport is a sound choice.

Can I replace just one or two 245/45R18 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.
