2018 Chevrolet Equinox — Tire Size & Pressure Guide

As an ASE-certified master technician, I’ve serviced countless compact SUVs, and the 2018 Chevrolet Equinox is one of the most common vehicles rolling into the bay. When it was redesigned for the 2018 model year, Chevy updated the chassis and suspension, which means getting the right tires, pressures, and wheel specs is critical for ride comfort, fuel economy, and safety.

Below is your comprehensive guide to the 2018 Chevrolet Equinox tire sizes, pressures, and wheel specifications.

Quick Answer: 2018 Chevrolet Equinox Tire Specs

Whether you’re checking your tire pressure on a road trip or buying a new set of wheels, here are the baseline factory specifications for the 2018 Equinox:

• OEM Tire Sizes: 225/65R17, 225/60R18, or 235/50R19 (depending on trim level)
• Recommended Cold Tire Pressure: 35 PSI (Front) / 35 PSI (Rear)
• Bolt Pattern: 5x114.3 mm (5x4.5")
• Wheel Sizes: 17x7.0", 18x7.5", 19x7.5" (Offset: 38-42mm depending on wheel)
• Load Index / Speed Rating: 102H (17-inch), 100H (18-inch), or 99H (19-inch)
• Spare Tire Size: T135/70R16 (Compact Temporary Spare) at 60 PSI
• TPMS Sensor Frequency: 315 MHz or 433 MHz (varies by production plant; always scan your specific VIN before replacing sensors)

Tire Sizes by Trim

Chevrolet offered several trims for the 2018 Equinox, each with specific wheel and tire packages. Check your specific trim or the tire placard located on your driver’s side door jamb to confirm your size.

Recommended Replacement Tires

When the factory tires wear out, you have a lot of great options. Based on shop experience and customer feedback, here are a few top-tier and budget-friendly replacement tires for the 2018 Equinox:

• Premium / Best Overall: Michelin Defender 2 – Outstanding tread life, quiet highway ride, and excellent all-season grip. (Price: High)
• Great Value / All-Season: Continental CrossContact LX25 – Fantastic wet traction and very comfortable over bumps. Highly recommended for daily drivers. (Price: Medium)
• Budget-Friendly: Cooper Endeavor Plus – A solid, reliable all-season tire that won't break the bank while still offering safe wet and dry performance. (Price: Low/Medium)

When to Inflate to Max Load PSI

Note: This section typically applies to Heavy Duty (HD) trucks towing massive loads.

Because the 2018 Chevrolet Equinox is a standard passenger SUV, you should not inflate your tires to the "Max Press" listed on the tire sidewall. The maximum sidewall pressure (usually 44 or 51 PSI) is the structural limit of the tire, not the operational recommendation. Always stick to the 35 PSI listed on your driver's door placard for standard driving, even when the vehicle is fully loaded with passengers and cargo.

Lug Nut Torque & Pattern

If you are rotating your own tires, installing a spare, or swapping to winter wheels, it is vital to tighten the lug nuts to the exact factory specification to prevent brake rotor warping or wheel separation.

• Bolt Pattern: 5x114.3 mm
• Lug Nut Size/Thread: M12 x 1.5
• Lug Nut Torque Specification: 100 lb-ft (140 Nm)

Tech Tip: Always use a calibrated torque wrench and tighten the lug nuts in a "star" or "crisscross" pattern. Re-torque the lug nuts after 50 to 100 miles of driving following a wheel installation.

Common Tire Issues for This Vehicle

1. Premature Wear on OEM Tires: Many 2018 Equinox owners report that the factory-installed tires (often Michelin Premier LTX or Hankook Kinergy) wear out relatively quickly, sometimes before 35,000 miles. Upgrading to a tire with a higher treadwear rating usually solves this.
2. Inner Edge Wear: The independent rear suspension on the Equinox can cause the tires to "toe out" or gain negative camber over time if the vehicle hits potholes. If you notice the inside edges of your tires wearing faster than the rest of the tread, get a four-wheel alignment immediately.
3. TPMS Sensor Battery Failure: By now, the batteries in your original TPMS sensors may be reaching the end of their 5 to 7-year lifespan. If your tire pressure light flashes for 60 seconds upon startup before staying solid, you likely have a dead sensor.
