Mechanic Tip
Cold Inflation Calibration Rule: Tire pressure drops roughly 1 PSI for every 10 degrees Fahrenheit drop in ambient temperature. Furthermore, driving even 1 mile generates internal friction that raises tire pressure by 3 to 5 PSI above true ambient resting level. Never set your tire pressure to the "Max PSI" molded on the tire sidewall, which indicates the maximum mechanical burst rating of the casing. Always calibrate tire pressure when the vehicle has rested for at least 3 hours, matching the cold PSI specified on the yellow-and-white driver-side door jamb placard.

Honda Accord tire size on the current (11th-gen) car is two stamps. LX, SE and EX-L Hybrid wear 225/50R17. Sport, Sport-L and Touring Hybrid wear 235/40R19. Honda did the plus-size at the factory. Your job is to match the one on the door, not the one on a nicer trim you saw in a photo.

Stock sizes by trim

These are the 2023-on North American sizes from Honda's own spec sheets. Earlier Accords used 225/50R17 and 235/40R19 in some years and 235/45R18 in others. A 2018 Touring is not this table.

Why the sticker beats the chart

Hybrids and gas cars share sizes by trim, not by powertrain. An EX-L Hybrid and an LX gas car can share the 17-inch stamp. A Sport Hybrid does not. The placard knows which one you bought.

This is not a fitment database

A Honda Accord can leave the factory on more than one size. Export markets, mid-year packages and previous-owner plus-sizes all disagree with a chart. Read the driver-door placard. Match width, aspect ratio and rim together.

Swapping to a different size

225/50R17 is about 25.9 inches tall. 235/40R19 is about 26.4. That is inside 3%, which is why Honda offers both on the same platform. Width is the bigger change. If you put Sport wheels on an LX, you are also putting a wider tire in a well that started narrower. Compare them: tire size comparison.

The 18-inch gap

Some earlier Accords and some markets used 235/45R18. That size sits between the two current stamps on diameter and is a common plus-one off the 17. It is not on the current US spec sheet. If your sticker says 235/45R18, believe the sticker, not this year's brochure.

Frequently asked questions

What tire size does a Honda Accord LX use?

225/50R17 on the current generation, shared with SE and EX-L Hybrid.

What tire size does an Accord Sport use?

235/40R19 on Sport, Sport-L and Touring Hybrid.

Can I put 19s on an Accord LX?

Diameter is close. Width and wheel offset are the real checks. Honda already sells that package as Sport. Use the comparison before you buy wheels.
