2019 Subaru Crosstrek — Tire Size, Pressure & Wheel Specs

As an ASE-certified master technician, I know that keeping your 2019 Subaru Crosstrek equipped with the right tires and proper air pressure is critical for its renowned all-wheel-drive capability, fuel economy, and safety. Whether you’re commuting on the highway or hitting the dirt trails for a weekend camping trip, the correct tire specs make all the difference.

Below is your comprehensive guide to the 2019 Subaru Crosstrek's tire sizes, pressures, wheel specs, and recommended replacements.

Quick answer: 2019 Subaru Crosstrek Tire Specs

Tire sizes by trim

Depending on which trim level of the 2019 Subaru Crosstrek you drive, it came from the factory with either 17-inch or 18-inch wheels.

Recommended replacement tires

When it's time to replace the tires on your Crosstrek, you want to match your typical driving conditions. Here are a few top-rated options across different price points:

• Falken Wildpeak A/T Trail (All-Terrain) – Mid-Tier: Extremely popular among Crosstrek owners. These are designed specifically for compact crossovers, offering mild off-road traction without ruining highway fuel economy or road noise.
• Michelin Defender T+H (All-Season) – Premium: If you keep your Crosstrek strictly on the pavement, this tire offers incredible tread life, a quiet ride, and superior wet-weather handling.
• Falken Sincera SN250 A/S (All-Season) – Budget: A great, affordable choice for daily commuting that still meets Subaru's load and speed requirements while offering respectable all-season traction.
• Yokohama Geolandar A/T G015 (All-Terrain) – Mid-Tier/Premium: Another excellent light-duty all-terrain tire that boasts the severe snow service (3-Peak Mountain Snowflake) rating.

When to inflate to max load psi

Note: This section primarily applies to Heavy-Duty (HD) trucks. Because the 2019 Subaru Crosstrek is a compact passenger vehicle, you do not need to inflate your tires to the "max psi" listed on the tire's sidewall (which is often 44 or 51 psi). You should stick to the recommended 33 psi front and 32 psi rear. If your vehicle is fully loaded with passengers and cargo for a long trip, you may safely increase the rear tire pressure by 1-2 psi to accommodate the weight, but never exceed the sidewall maximum.

Lug nut torque & pattern

Proper wheel installation is vital to prevent warped brake rotors or a loose wheel.

• Bolt Pattern: 5x100
• Lug Nut Torque: 89 ft-lbs (120 Nm)
• Thread Size: M12 x 1.25

Always tighten your lug nuts in a star pattern to ensure even clamping force across the wheel hub. If you remove the wheels, be sure to re-torque the lug nuts after 50 to 100 miles of driving.

Common tire issues for this vehicle

1. AWD System Sensitivity: Subaru's Symmetrical All-Wheel Drive system is highly sensitive to differences in tire diameter. If you blow a tire and the remaining three are significantly worn (more than 2/32nds of an inch difference in tread depth), you cannot just replace one tire. Doing so can overheat and damage the AWD center differential. You must either shave the new tire down to match the others or replace all four tires at once.
2. Uneven Wear from Alignment: Crosstreks driven on rough roads or light off-road trails frequently get knocked out of alignment. If you notice the inside or outside edges of your tires wearing out faster than the center, have your camber and toe specs checked immediately.
3. TPMS Sensor Battery Life: By the time a 2019 model is 5 to 7 years old, the internal batteries in the 433 MHz TPMS sensors may begin to fail, triggering the tire pressure light on your dash even when the tires are fully inflated.
