2019 Toyota Tundra Tire Size & Pressure Specs

When it comes to maintaining your 2019 Toyota Tundra, having the right tires at the correct pressure is critical for ride quality, towing capacity, and safety. As an ASE-certified master technician, I’ve put together this comprehensive guide to help you find all the tire, wheel, and pressure specifications for your Tundra.

Quick answer

Here are the essential tire and wheel specs for a 2019 Toyota Tundra:

• OEM tire sizes: 255/70R18, 275/65R18, or 275/55R20 (depending on trim)
• Recommended cold tire pressure: 30–33 PSI (front/rear, check your door placard)
• Bolt pattern: 5x150 mm
• Wheel size: 18x8.0 or 20x8.0 (Offset: +60 mm)
• Load index/speed rating: 111H, 113T, or 114T (varies by tire size)
• Spare tire size: Full-size matching spare
• TPMS frequency: 315 MHz

Tire sizes by trim

Toyota offered a variety of trims for the 2019 Tundra, ranging from the work-ready SR to the luxurious 1794 Edition. Here is a breakdown of the factory tire sizes by trim level:

Recommended replacement tires

If your Tundra is due for a new set of tires, here are some of the most popular and highly-rated options depending on your budget and driving needs:

1. Michelin Defender LTX M/S (Premium) – Exceptional highway ride, long tread life, and great wet traction. Perfect for daily driving and light towing.
2. BFGoodrich All-Terrain T/A KO2 (Premium) – The gold standard for off-roading. Severe snow rated (3PMSF) with aggressive sidewall lugs. Great for TRD models.
3. Falken Wildpeak A/T3W (Mid-Range) – A fantastic all-terrain tire that balances on-road comfort with off-road durability and wet traction.
4. Cooper Discoverer AT3 4S (Mid-Range) – A solid all-rounder offering a quiet highway ride while maintaining good dirt and gravel capabilities.

When to inflate to max load psi

While the 2019 Tundra is a half-ton (light-duty) truck rather than a heavy-duty (HD) truck, many owners upgrade to LT (Light Truck) tires (Load Range E) for towing and hauling.

If you are running standard P-metric tires, stick to the 30-33 PSI listed on your driver's side door jamb for normal driving. However, if you are towing a heavy trailer or loading the bed to its maximum payload capacity, you may need to increase the rear tire pressure. For standard tires, do not exceed the max PSI listed on the tire sidewall (usually 44-51 PSI). If you have upgraded to LT-metric tires, you may need to run 45-50 PSI daily, increasing to 65-80 PSI in the rear when heavily loaded. Always use a load inflation table specific to your tire size and load range.

Lug nut torque & pattern

Proper wheel torque is crucial to prevent brake rotor warping and ensure wheel security.

• Bolt Pattern: 5x150 mm
• Lug Nut Torque (Alloy Wheels): 97 ft-lbs
• Lug Nut Torque (Steel Wheels): 154 ft-lbs (Note: Always verify with your owner's manual, as Toyota's 5-lug steel wheels require significantly higher torque than the alloys).
• Socket Size: 22 mm

Always hand-thread your lug nuts first, and tighten them in a star (crisscross) pattern using a calibrated torque wrench. Re-torque the wheels after 50 to 100 miles of driving.

Common tire issues for this vehicle

The 2019 Toyota Tundra is generally very reliable, but there are a few tire and alignment-related quirks to watch out for:

• Outer edge wear: Tundras are notorious for wearing out the outer shoulders of the front tires. This is often due to factory alignment settings prioritizing stability over tire life. A competent alignment shop can adjust the camber and toe to minimize this.
• TPMS sensor failure: The 315 MHz sensors feature internal batteries that typically last 7-10 years. Because the 2019 Tundra is approaching this age, you may start experiencing dead TPMS sensors. If one fails, it is usually best to replace all four (and the spare, if equipped) at your next tire change.
• Vibration at highway speeds: Tundras are sensitive to wheel balance. If you feel a shake at 60-70 mph, request a "road force balance" from your tire shop to ensure the tire and wheel are perfectly matched.
