How to Identify Your Honda Accord Tire Size
Start with the driver-side doorjamb. The Tire and Loading Information Label lists the original tire size, proper cold tire pressure, and load information for your Accord. This label is more important than a generic chart because it applies to your specific vehicle.
- Open the driver’s door and find the Tire and Loading Information Label on the door edge or doorjamb.
- Read the front and rear tire size listed on the label. Most 2020 Accord sedan trims use the same size on all four wheels.
- Compare it with the tire sidewall on your current tires. The sidewall will show a code such as 225/50R17 or 235/40R19.
- Match the load index and speed rating shown on your current tire, owner’s manual, or tire shop fitment screen. Do not choose a lower load rating than required.
- Ask a Honda dealer or tire professional if your current wheels or tires do not match the door-jamb label.
What the Tire Size Code Means
A tire marked 225/50R17 means the tire is 225 mm wide, the sidewall height is 50% of the tire width, it uses radial construction, and it fits a 17-inch wheel. A tire marked 235/40R19 is wider, has a shorter sidewall, and fits a 19-inch wheel.
Warning: Do not choose a tire only because it “fits” the wheel. The overall diameter, load index, speed rating, wheel width, clearance, and TPMS behavior all matter. The wrong size can affect handling, ride comfort, braking, speedometer accuracy, and tire wear.
What You Need to Know About OEM Specs for Your Accord
OEM specs matter because Honda selected each tire and wheel combination to support the Accord’s steering feel, braking, stability control, ride comfort, and fuel economy. The safest replacement choice is the same size shown on your door-jamb label or a Honda-approved equivalent.
For the 2020 Accord sedan, Honda’s official wheel-and-tire information shows 225/50R17 tires on 17-inch wheels for LX, EX, EX-L, and EX-L 2.0T models, while Sport, Sport 2.0T, and Touring 2.0T use 235/40R19 tires on 19-inch wheels. If your Accord has aftermarket wheels, confirm the wheel width and offset before buying tires.
NHTSA reported 511 deaths in tire-related crashes in 2024, which is a reminder that tire size, inflation, tread depth, and condition are safety items—not just maintenance details.
Check Tire Pressure the Right Way
Use the cold tire pressure listed on the driver-side door-jamb label or in the Honda owner’s manual resources. Do not inflate tires to the maximum PSI printed on the tire sidewall unless a qualified technician tells you to do so for a specific service reason.
- Check pressure at least once a month when tires are cold.
- Check before long trips or heavy-load driving.
- Recheck pressure after large temperature swings.
- Do not rely only on the TPMS light; it usually warns after a tire is already significantly underinflated.
Pro Tip: Keep a small tire pressure gauge in the glove box. A one-minute cold-pressure check can prevent uneven wear, poor fuel economy, and TPMS surprises.
When to Replace Your Honda Accord Tires for Optimal Performance
Replace your Accord tires when tread depth, age, visible damage, or driving behavior shows the tire is no longer safe. The legal minimum is not always the best practical replacement point, especially if you drive in rain, snow, or on rough roads.
| Indicator | What It Means | Action Required |
|---|---|---|
| Tread depth at 2/32 inch | NHTSA says tires are not safe when worn to this depth. | Replace immediately. |
| Weak wet-road grip or hydroplaning | The tire may be unsafe in rain even before it reaches the legal minimum. | Inspect and consider replacing earlier. |
| Cracks, bulges, cuts, or exposed cords | The tire structure may be damaged. | Do not ignore it; have the tire inspected or replaced. |
| Uneven shoulder, center, or cupping wear | Possible pressure, alignment, suspension, or rotation issue. | Check pressure, rotate if appropriate, and schedule alignment or inspection. |
| Older tires with hard rubber or sidewall cracking | Tires age even when tread remains. | Follow the tire maker’s age guidance and have them inspected regularly. |
You can check tread depth with a tread depth gauge or the penny test. If the top of Lincoln’s head is visible when the penny is inserted upside down into the tread, the tire is at or near the replacement point. For better wet-weather confidence, many drivers replace tires before they reach the absolute 2/32 inch minimum.

Maintain Your Tires Effectively
Good tire maintenance helps your 2020 Honda Accord ride smoothly, stop predictably, and wear tires evenly. NHTSA recommends checking tire pressure and tread at least monthly, and it says tire pressure should be checked when tires are cold.
- Check cold pressure monthly: Use the PSI on the door-jamb label, not the maximum PSI on the tire sidewall.
- Inspect tread monthly: Look for low tread, wear bars, nails, cuts, bubbles, cracks, or exposed cords.
- Rotate tires when recommended: NHTSA suggests 5,000–8,000 miles if the vehicle manufacturer recommends rotation. Honda owners should also follow the Maintenance Minder and owner’s manual.
- Balance new tires: New tires should be balanced during installation to reduce vibration.
- Check alignment if wear is uneven: Pulling, off-center steering, feathering, or cupping can point to alignment or suspension issues.
- Calibrate TPMS after service: If your Accord requires TPMS calibration after inflation, rotation, or replacement, follow the owner’s manual or have the shop do it.
Note: A TPMS warning light is not a replacement for a pressure gauge. TPMS may not alert you until a tire is already significantly underinflated.
Choosing Tires for Your Conditions
Once you know your Accord’s correct size, choose the tire type based on your driving conditions. Tire size gets the tire on the car; tire type determines how it feels in rain, heat, snow, commuting, and highway driving.
- Touring or grand-touring all-season tires: Best for most Accord drivers who want comfort, quiet ride quality, long tread life, and year-round use in mild climates.
- Performance all-season tires: A good match for Sport and Touring trims if you want sharper steering, but they may ride firmer and wear faster.
- Winter tires: Best for regular snow, ice, and freezing temperatures. Use a complete matching set of four.
- Summer tires: Strong dry and wet warm-weather grip, but not safe for cold or snowy conditions.
Also check the tire’s UTQG treadwear, traction, and temperature grades. NHTSA’s Uniform Tire Quality Grading System helps compare treadwear, traction performance, and temperature resistance for passenger tires sold in the United States.
Warning: If your 2020 Accord currently has a tire size that differs from the door-jamb label, do not assume it is correct. Confirm wheel size, clearance, load rating, and speedometer impact with a tire professional before replacing the set.
