2023 Subaru Forester — Tire Size & Pressure Guide

As an ASE-certified master technician, I regularly service the fifth-generation Subaru Forester. The 2023 model continues Subaru’s tradition of standard Symmetrical All-Wheel Drive, which means proper tire maintenance, sizing, and pressure are absolutely critical to prevent drivetrain damage. Below is your comprehensive guide to the 2023 Subaru Forester’s tire, wheel, and pressure specifications.

Quick answer: 2023 Subaru Forester Tire & Wheel Specs

Here are the essential factory specifications you need to know before buying tires or wheels for your 2023 Forester:

• OEM Tire Sizes: 225/60R17 or 225/55R18 (depending on trim)
• Recommended Cold Tire Pressure: 33 PSI Front / 32 PSI Rear (Standard models); 35 PSI Front / 33 PSI Rear (Wilderness trim)
• Bolt Pattern: 5x114.3 (5x4.5")
• Wheel Size & Offset: 17x7.0J or 18x7.0J with a +48mm offset
• Load Index & Speed Rating: 99H (17-inch standard), 98H (18-inch), or 99T (Wilderness A/T)
• Spare Tire Size: T145/80D17 compact spare (The Wilderness trim includes a full-size spare)
• TPMS Frequency: 433 MHz

Tire sizes by trim

Subaru keeps things relatively simple across the Forester lineup, utilizing two main wheel diameters. The Wilderness trim features a more aggressive all-terrain tire compared to the standard all-season highway tires found on other trims.

Always check the tire information placard on the driver’s side door jamb of your specific vehicle to confirm.

Recommended replacement tires

Because the Forester relies heavily on its AWD system, you should always replace tires in sets of four. Here are my top recommendations for the 2023 Forester based on durability, ride comfort, and seasonal performance:

1. Michelin CrossClimate2 (Premium / $$$): An outstanding all-weather tire. It offers phenomenal snow and wet traction without sacrificing summer driving dynamics. Highly recommended if you live in areas with unpredictable winters but don't want dedicated winter tires.
2. Falken Wildpeak A/T Trail (Mid-Range / $$): If you want the rugged look and capability of the Wilderness trim on your Premium or Sport, this is the tire. It’s engineered specifically for unibody crossovers to provide light off-road traction without destroying highway fuel economy.
3. General AltiMAX RT45 (Budget-Friendly / $): A fantastic touring all-season tire that delivers excellent tread life, a quiet ride, and reliable everyday performance for a fraction of the cost of premium brands.

When to inflate to max load psi

The concept of inflating tires to a "Max Load PSI" (often 65-80 PSI) applies specifically to Heavy Duty (HD) trucks with LT (Light Truck) tires carrying massive payloads.

The 2023 Subaru Forester is a passenger crossover equipped with P-metric (Passenger) tires. You should never inflate your Forester's tires to the "Max PSI" listed on the tire sidewall. Doing so will result in a harsh ride, uneven center-tread wear, and an increased risk of a blowout. Always stick to the 33/32 PSI (or 35/33 PSI for Wilderness) listed on the driver's door placard, regardless of how much cargo you are hauling.

Lug nut torque & pattern

When installing new wheels or rotating your tires, proper torque is essential to prevent warped brake rotors or loose wheels.

• Lug Nut Torque: 89 lb-ft (120 Nm)
• Bolt Pattern: 5x114.3
• Thread Pitch: M12 x 1.25

Always tighten lug nuts in a star (crisscross) pattern to ensure the wheel seats evenly against the hub. I recommend re-checking the torque after driving 50 to 100 miles.

Common tire issues for this vehicle

1. AWD System Sensitivity: Subaru’s AWD system is notoriously sensitive to variations in tire diameter. A difference of more than 2/32-inch in tread depth between tires can cause the center differential to bind and overheat. If you suffer an unrepairable flat on one tire, you must either replace all four tires or have the single new tire "shaved" down to match the tread depth of the remaining three.
2. Premature Outer Edge Wear: Foresters often develop slight outer edge wear on the front tires due to the vehicle's cornering dynamics and factory alignment specs. Rotating your tires every 5,000 to 6,000 miles is critical to spreading out this wear and maximizing tire life.
3. TPMS Sensor Battery Depletion: While your 2023 model is still new, note that the 433 MHz TPMS sensors have internal batteries that typically last 7–10 years.
