225/55R18 tires

225/55R18 is the Subaru Forester size: the Premium, Sport and Limited since 2019 use it, and so do the 2024 Crosstrek Sport and Limited. Mitsubishi fits it to the Eclipse Cross, the Outlander SEL with 18-inch wheels and the Outlander Sport. Below are real prices for 214 tires in stock, three picks with the specifications behind them, and the winter decision that most Forester owners face.

What 225/55R18 tires cost

Prices are per tire, before mounting and balancing. A set of four in the mid range comes to roughly $500 to $780, and a brand rebate can take another $50 to $110 off, see this month's deals.

A Forester size, and a winter size

The Forester is a popular car in snow country, and many owners there run a second set of tires. With 225/55R18 there are three workable approaches: an all-season like the three picks below, swapped for winter tires when the snow comes; a dedicated winter tire on a second set of 18-inch wheels; or an all-weather tire with the three-peak mountain snowflake symbol used all year. The last saves the swap at some cost in tread life and summer precision. None of our three picks is an all-weather or winter tire.

Whatever you choose, keep tread depth equal on all four corners. The Forester and Crosstrek have full-time all-wheel drive, and mismatched circumferences make the center coupling work all the time.

98 or 102: two load ratings

Tires in this size come in 98 standard-load and 102 extra-load versions. Our budget pick is listed as 102W, the other two as 98. If your placard specifies 98, all three qualify; the extra-load tire is stiffer and may ride a little firmer. The Subaru Legacy is sometimes listed with this size, but tiresize.com lists the 2020 to 2024 Legacy on 225/55R17 or 225/50R18, so Legacy owners should search for those sizes.

The size stands about 27.7 inches tall, turns 727 times per mile and fits 18-inch rims from 6 to 8 inches wide, so a set on the factory wheels is a direct swap on every vehicle listed below.

What the numbers on the sidewall mean

A 225/55R18 tire is 225 millimeters wide, its sidewall is 55 percent of that (about 4.9 inches tall), and it mounts on a 18-inch wheel. That works out to an overall diameter of roughly 27.7 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 102W on the Lexani LXUHP-207 (1,874 lb per tire, rated to 168 mph) and 98H on the Cooper Endeavor Plus and Goodyear Assurance Finesse (1,653 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.

Lexani LXUHP-207, $77.99. An ultra-high-performance all-season at a low price, listed here as 102W. The retailer's pages give both a 50,000- and a 40,000-mile warranty, with a 500 A A treadwear grade in a representative size. A performance tire is not the natural fit for a Forester, but it is the lowest-priced way into the size.

Cooper Endeavor Plus, $167.99. Cooper's crossover touring tire, with a 65,000-mile warranty, a 680 A A treadwear grade and a 45-day satisfaction guarantee. In this size it is a 98H tire, matching the Forester's standard load index, and the safest choice for an all-wheel-drive family car.

Goodyear Assurance Finesse, $206.96. A touring all-season with a compound tuned for fuel efficiency and grip on wet and snowy roads, with a 540 A A treadwear grade in a representative size. The retailer's spec does not state a mileage warranty, so check the listing. It is a 98H tire in this size.

What 225/55R18 tires cost across the whole range

Of the 271 tires listed in this size, 214 are in stock today. The lowest price is the Lionhart LH-503 at $83.96, a 102W tire. The median is $159.21; a third of the tires cost $124.96 or less, and the top five percent start above $245.15. 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 Cooper Endeavor Plus, our mid-range pick here at $167.99, is also stocked in 225/60R17 ($149.99), 225/65R17 ($157.99), 235/55R18 ($178.99) and 235/60R18 ($179.99). The Goodyear Assurance Finesse, our premium pick here at $206.96, is also stocked in 215/65R17 ($152.96). 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 in this size: what the states actually require

Crossovers in this size come both ways, front-wheel drive and all-wheel drive, and the difference matters under the traction laws. In Colorado the Passenger Vehicle Traction Law applies on the 126 miles of I-70 between Dotsero and Morrison from September 1 to May 31. You need either an all-wheel-drive or four-wheel-drive vehicle, or tires marked M+S, 3PMSF or rated all-weather by the manufacturer, and in every case at least 3/16 inch of tread. Fines start at $130. An AWD crossover passes on the vehicle alone; a front-wheel-drive one does not, and then the tire marking is what the trooper checks. If you want one set year-round in the snow belt, an all-weather tire with the 3PMSF symbol is the better answer than a plain all-season.

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

Frequently asked questions

How much do 225/55R18 tires cost?

Expect $84–$125 per tire for a budget brand, $125–$195 for a mid-range tire like the Cooper Endeavor Plus, and $195–$245 for a premium tire like the Goodyear Assurance Finesse. A set of four therefore starts at about $336. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 225/55R18 tires?

225/55R18 is original equipment on Subaru Forester (2019-2024, Premium/Sport/Limited), Subaru Crosstrek (2024, Sport/Limited), Mitsubishi Eclipse Cross (2018-2024), Mitsubishi Outlander (2014-2021, SEL 18 in) and Mitsubishi Outlander Sport (2011-2024, 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 225/55R18 tire?

For most drivers our mid-range pick, the Cooper Endeavor 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 Goodyear Assurance Finesse is worth the extra. On a tight budget the Lexani LXUHP-207 is a sound choice.

Can I replace just one or two 225/55R18 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.
