Chevy Equinox Tire Size Guide

Since 2005, the Chevrolet Equinox has used wheels from 16 to 20 inches, each sized for ride comfort, handling, fuel economy, and speedometer accuracy. When looking for new tires, always start with the factory size on the driver’s door jamb and match the load index and speed rating before exploring tread upgrades. To help you get started, our Pride Chevrolet team will walk you through every Equinox tire size to help you get the right ones for your car.

How To Read Tire Size Numbers and Letters: What the Code Means

A tire’s sidewall packs a complete data sheet into a short alphanumeric string.

• Type: P marks a passenger-car tire, while LT stands for light-truck service. If the code doesn’t have a letter, the tire is a Euro-metric passenger tire.
• Width: The first three digits show the section width, measured in millimeters from sidewall to sidewall.
• Aspect ratio: The two-digit number after the slash stands for the sidewall height as a width percentage, so 65 means the sidewall is 65 percent as tall as the tread is wide.
• Construction: R indicates radial plies (found in virtually every modern Equinox tire), whereas a D would signal a bias-ply design.
• Wheel diameter: The next two digits are the rim size in inches — 17, 18, 19, or 20 inches for factory-spec Equinox wheels.
• Load index: One to three numbers after the rim diameter specify the maximum weight each tire can safely carry. For example, an index of 102 equals 1,874 pounds.
• Speed rating: The final letter (H, V, W, etc.) designates the tire’s certified top-speed capability under load.

Occasionally, you’ll see a service suffix: XL (extra load) tires carry higher pressures for heavier cargo, while SL (standard load) tires meet the base requirement on most front-drive Equinox trims. Matching every element — especially load index and speed rating — ensures the new set meets Chevrolet’s engineering targets for braking distance, fuel economy, and traction-control accuracy.

Tire Sizes by Model Year

While tire sizes for the Chevrolet Equinox have remained fairly consistent over the years, there are slight differences depending on which generation Equinox you have.

Chevrolet Equinox I (2005-2009)

The first-generation Chevrolet Equinox came with factory tire sizes, including P235/65R16 and P235/60R17. Early all-wheel-drive Sport trims could also accommodate 18-inch dealer accessory wheels. However, to maintain the proper function of the rear coupler, the overall tire diameter must be within 28 inches.

Chevrolet Equinox II (2010-2015)

For the second-generation Chevrolet Equinox, tire options varied by trim. Factory sizes included P225/65R17, P235/55R18, and P235/55R19. The shift to 19-inch wheels required a lower profile tire to maintain the correct overall circumference, so mixing 18- and 19-inch sets is strongly discouraged.

Chevrolet Equinox II Facelift (2016-2017)

The refreshed Chevrolet Equinox retained many key specs, offering P225/65R17 and P235/55R18 as standard tire sizes. The bolt pattern remained unchanged — meaning that wheels from the previous generation still fit.

Chevrolet Equinox III (2018-2020)

Chevy equipped this Equinox generation with a variety of factory tire sizes depending on trim level: P235/65R16 for the base steel wheels, P225/65R17 for L and LS trims, P225/60R18 for the LT, and P235/50R19 for the Premier.

Chevrolet Equinox III Facelift (2021-2023)

For the Chevrolet Equinox facelift, factory tire sizes included P225/60R18 for the RS trim and P235/50R19 for the Premier and RS blackout editions.

Chevrolet Equinox IV (2024-Onward)

The latest Chevrolet Equinox models, including all-electric variants, come with factory tire sizes of 235/65R17, 235/60R18, and 235/50R20. While the new chassis retains the familiar 5-by-115 mm bolt pattern, the wheel offset is pushed 5 mm farther outward, which may require spacers when fitting older wheels.

Choosing the right tires depends on what you’re looking for.

Tire Maintenance and Replacement Tips

Knowing how to care for your tires and when to replace them is a crucial part of automobile ownership.

When To Replace Your Chevrolet Equinox Tires

Tread depth below 4/32 of an inch will impact your braking ability, and anything under 2/32 of an inch fails safety inspections. Uneven wear on the shoulders hints at misalignment, while center wear suggests overinflation.

How To Maintain Optimal Tire Pressure for Your Chevrolet Equinox

Chevrolet stamps the recommended cold pressure — typically 35 psi — on the driver-door label. Stick to that for the best fuel economy and tire-pressure monitoring accuracy. Check pressures monthly and every time ambient temperatures swing more than 10 degrees Fahrenheit.

Alignments, Rotations, and Balancing

Rotate your tires every 6,000 miles and realign them annually or after pothole impacts. Road-force balancing can fix highway shimmying and extend suspension life.
