2019 Chevrolet Silverado 1500 Tire Size & Pressure Guide

As an ASE-certified master technician, I've serviced countless 2019 Chevrolet Silverado 1500s. Completely redesigned for the 2019 model year (the T1XX generation), this truck comes with a variety of wheel and tire options depending on the trim level and package. Whether you're hauling materials, towing a camper, or just commuting, having the correct tire specifications is crucial for safety and performance.

Here is your comprehensive tire and wheel guide for the 2019 Chevy Silverado 1500.

Quick answer: 2019 Chevrolet Silverado 1500 Tire Specs

• TPMS Frequency: 433 MHz

Tire sizes by trim

Chevrolet offered a wide range of trims for the 2019 Silverado 1500. Below is a breakdown of the factory tire sizes you can expect to see by trim level.

Note: Trail Boss models typically come with LT (Light Truck) rated Goodyear Wrangler DuraTrac tires for off-road durability.

Recommended replacement tires

When it's time to replace the rubber on your Silverado, these are the tires I recommend based on performance, longevity, and customer feedback.

• Premium Highway/All-Season: Michelin Defender LTX M/S – Exceptional tread life, a smooth ride, and great wet traction. Best for highway commuters and light towing.
• Mid-Range All-Terrain: Falken Wildpeak A/T3W – Highly rated for snow and off-road capability without producing excessive highway hum. Excellent value.
• Premium Off-Road (Trail Boss replacements): BFGoodrich All-Terrain T/A KO2 – A classic, tough LT-rated tire that resists punctures and provides massive grip in dirt and mud.
• Budget All-Season: Kumho Crugen HT51 – A very capable, affordable tire that provides a quiet ride and decent mileage for those on a tighter budget.

When to inflate to max load psi

While the 2019 Silverado 1500 is a half-ton truck (not a Heavy Duty 2500/3500), you may still need to adjust tire pressures when maxing out your payload or towing capacity.

The door placard’s 35 PSI recommendation is calibrated for a balance of ride comfort and everyday fuel economy. However, if you are towing a heavy trailer or loading the bed to its maximum capacity, you should increase the rear tire pressure to reduce sidewall flex and heat buildup.

• Standard Load (SL) tires: Increase to 38–40 PSI (do not exceed the max cold PSI listed on the tire's sidewall, usually 44 PSI).
• Light Truck (LT) tires: If your truck has factory LT tires (like the Trail Boss), you may need to increase the rear pressure to 45–50 PSI when heavily loaded. Again, consult the sidewall markings.

Lug nut torque & pattern

Getting the lug nuts torqued properly is a critical safety step that is often overlooked.

• Lug Nut Torque: 140 ft-lbs (190 Nm)
• Bolt Pattern: 6x139.7mm (often referred to as 6x5.5")
• Thread Size: M14 x 1.5

Tech Tip: Always use a calibrated torque wrench and tighten the nuts in a crisscross (star) pattern. Because 140 ft-lbs is quite high, never rely on an impact wrench alone to secure your wheels. Retorque the wheels after 50 to 100 miles of driving following a tire change.

Common tire issues for this vehicle

1. Outer edge wear on front tires: The Silverado 1500 is a heavy vehicle. Taking corners aggressively can quickly scrub off the outer shoulders of the front tires. Regular rotations (every 5,000 to 7,500 miles) are mandatory to even this out.
2. TPMS sensor battery failure: While 2019 is still relatively new, the 433 MHz sensors have a battery life of about 5-7 years. If you're experiencing random TPMS light flashes or loss of pressure readings, it might be time to replace the sensors during your next tire change.
3. Cupping on rear tires (unloaded driving): If you drive with an empty bed most of the time but run high tire pressures, the rear tires can bounce and develop a cupped wear pattern over time. Stick to 35 PSI for unladen driving.
