2016 Honda Accord Sport Tire Size: Full OEM Wheel & Tire Specs

The 2016 Honda Accord Sport comes with a 235/45R18 tire size mounted on 18-inch alloy wheels. That single spec answers most of what owners search for, but it leaves out the details that actually matter when you replace tires, hunt for a spare set, or shop for OEM rims. Below is the full breakdown of factory tire and wheel sizes for the 2016 Accord Sport, what each number means, and how the Sport differs from the rest of the lineup.

2016 Honda Accord Sport Tire Size at a Glance

The Sport trim sat in the middle of the 2016 Accord range and was the value pick for buyers who wanted the bigger wheels without the Touring price. Its factory rolling stock looked like this:

• Tire size: 235/45R18
• Wheel size: 18-inch alloy
• Bolt pattern: 5x114.3 (also written 5x4.5")
• Center bore: 64.1 mm
• Recommended tire pressure: 32 psi front and rear (confirm on your driver-door jamb sticker)

Both the four-cylinder and V6 versions of the 2016 Accord Sport sedan used the same 235/45R18 fitment. The size is identical front and rear, which means rotation is straightforward and you only ever buy one tire size.

Reading the 235/45R18 Tire Code

Tire sidewall codes look cryptic until you split them apart. Here is what each segment of 235/45R18 tells you about the Accord Sport's tires:

• 235 — section width in millimeters, measured across the widest part of the tire.
• 45 — aspect ratio. The sidewall height equals 45% of the width, so roughly 105 mm tall. A lower number means a shorter, sportier sidewall.
• R — radial construction, standard on virtually every passenger car today.
• 18 — wheel diameter in inches. The tire is built to seat on an 18-inch rim.

The Sport's 45-series sidewall is shorter than the 55-series tires on the EX and EX-L trims. That shorter sidewall sharpens steering response and is part of why the Sport felt firmer than other Accords, at the cost of a slightly stiffer ride over rough pavement.

Tire Sizes Across the 2016 Accord Lineup

Knowing how the Sport compares to its siblings helps if you are cross-shopping used Accords or sourcing wheels from a different trim. The 2016 Accord sedan offered three distinct wheel and tire combinations:

The Sport and Touring shared the same 18-inch tire size, though the wheel finishes differed. The LX rode on the tallest sidewall and smallest wheel, giving it the softest ride and best fuel economy of the group.

Why the Sport Uses Wider, Lower-Profile Tires

Honda fitted the Sport with a wider 235-section tire and a shorter 45-series sidewall to match its tuned character. The wider contact patch improves dry grip and cornering stability, while the lower profile reduces sidewall flex during quick steering inputs. The trade-off is a ride that transmits more road texture into the cabin and tires that cost a little more to replace than the LX's 16-inch rubber.

This is the same engineering logic behind most "sport" trims: larger diameter, wider tread, shorter sidewall. If you own a Sport and find the ride too firm, dropping to a 17-inch setup from an EX is mechanically possible because the bolt pattern and center bore match, though it changes the look and slightly raises the sidewall.

2016 Accord Sport Wheel and Rim Specifications

Tire size only tells half the story. If you are replacing a bent, curbed, or corroded wheel, the rim specs have to match for the tire to seat and the wheel to bolt up correctly. The 2016 Accord Sport uses:

• Diameter: 18 inches
• Bolt pattern: 5x114.3 mm — five lugs on a 114.3 mm circle, the standard pattern across the 2013–2017 Accord generation.
• Center bore: 64.1 mm — the hub-centric bore that locates the wheel on the hub. A mismatched bore can cause vibration even when the bolt pattern is right.
• Lug type: conical seat lug nuts, 12x1.5 thread.

Because the entire 9th-generation Accord (2013 through 2017) shares the 5x114.3 bolt pattern and 64.1 mm center bore, an 18-inch wheel from a Touring or a later 2017 Sport will physically bolt onto a 2016 Sport. Always confirm the offset is close to factory so the tire sits correctly inside the fender and clears the brakes and suspension.

Replacing OEM Wheels on a 2016 Accord Sport

Curb rash, pothole damage, and winter corrosion are the usual reasons Accord owners go looking for a replacement rim. When that happens, an original-equipment wheel is the safest match because it carries the exact diameter, bolt pattern, center bore, and offset Honda engineered for the car. A genuine OEM rim drops in without spacers, bore rings, or guesswork, and it keeps the factory tire size and ride quality intact.

At OEM Rim Shop we stock factory original 18-inch Accord Sport wheels along with the 16-inch and 17-inch fitments from other trims, so you can match a single damaged wheel or refresh a full set. Searching by your year, make, and model returns only the rims that actually fit a 2016 Accord, which removes the risk of ordering a wheel with the wrong offset or bore.

Tire Pressure and Maintenance Notes

The factory recommended pressure for the 2016 Accord Sport is 32 psi front and rear, but the figure printed on the sticker inside your driver-side door jamb is the authority for your specific car. Check pressure cold, before the car has been driven, since heat from rolling raises the reading.

A few habits keep the 235/45R18 tires lasting their full tread life:

• Rotate every 5,000 to 7,500 miles. Because all four tires are the same size, a simple front-to-rear rotation works.
• Watch the shorter sidewall around potholes — 45-series tires offer less cushion against rim damage than the LX's taller 65-series rubber.
• Keep an eye on inner-edge wear, an early sign of alignment drift that low-profile tires reveal quickly.

Plus-Sizing and Winter Tire Options

Some owners want a different look or a dedicated cold-weather set, and the Sport's 18-inch platform gives you room to move in either direction. Staying within roughly 3 percent of the factory overall diameter keeps your speedometer accurate and avoids rubbing.

• Winter setup: a common move is a smaller 17-inch wheel with a 225/50R17 or the EX's 215/55R17. The taller sidewall absorbs frozen potholes better and narrower tires can bite through snow more effectively.
• Staying at 18 inches: 235/45R18 is widely stocked across all-season, summer performance, and touring categories, so replacement tires are easy to find and competitively priced.
• Going wider: stepping up to a 245-section tire is possible on the factory 18-inch wheel for some buyers, but it tightens fender clearance and is best confirmed against the specific wheel width before committing.

Whatever direction you choose, the wheel still has to honor the 5x114.3 bolt pattern and 64.1 mm center bore. Those two numbers are the non-negotiables for any wheel that bolts onto a 2016 Accord Sport.

The bolt pattern is 5x114.3 mm (5x4.5"), with a 64.1 mm center bore. This pattern is shared across the entire 2013–2017 Accord generation.

Can I put 17-inch wheels on a 2016 Accord Sport?

Yes. Because the Sport shares its 5x114.3 bolt pattern and 64.1 mm center bore with the EX and EX-L trims, you can fit their 17-inch wheels and 215/55R17 tires. Confirm the offset is near factory so the wheels clear the brakes and sit properly in the fenders.

What tire pressure should a 2016 Accord Sport run?

Honda recommends 32 psi front and rear for the 2016 Accord Sport. The exact number for your car is printed on the driver-door jamb sticker; check pressure when the tires are cold.
