The 2021 Honda Trucks Passport sits in the modern midsize crossover space with a strong emphasis on everyday road use, cargo flexibility, and light-adventure versatility. It is the kind of vehicle where tire choice affects not just appearance, but also how confidently the Passport carries its weight and fills the wheel openings. For this model year, fitment centers on two 20-inch radial sizes: 245/50R20 and 265/45R20, with size selection tied to the specific sub-model. That makes the real decision less about old-vs-new construction and more about confirming trim, understanding the difference between the two metric sizes, and matching the tire to the vehicle’s wheel setup and intended use.
Which Tire Size Is Right for The 2021 Honda Trucks Passport
The 2021 Honda Trucks Passport uses two primary tire sizes, and both are radial tires for 20-inch wheels. The first step is confirming the exact sub-model, because EX-L and Sport use 245/50R20 while Elite and Touring use 265/45R20. Once that is settled, the focus shifts to choosing the right modern metric radial for the wheel and vehicle setup already on the Passport.
245/50R20 is a modern metric radial size in which 245 refers to nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2021 Honda Trucks Passport, this size suits sub-models that use a slightly narrower section width than the 265 option while remaining within the same 20-inch wheel diameter family. It is a practical fitment to evaluate when the Passport is equipped for the EX-L or Sport setup. Wheel width, tire condition, and any prior changes to the vehicle should still be checked before replacement.
265/45R20 is also a modern metric radial size, with 265 indicating nominal section width in millimeters, 45 indicating the aspect ratio, R for radial construction, and 20 for the wheel diameter. On the 2021 Honda Trucks Passport, this size is used on sub-models that carry a wider tire than the 245/50R20 fitment while keeping the same 20-inch rim diameter. It is the size to evaluate for Elite and Touring configurations. Tire selection should still be matched to the actual wheel setup and checked for clearance if the Passport has been modified from stock.
Tire fitment for the 2021 Honda Trucks Passport depends on the exact sub-model rather than a single size shared across the lineup. Checking the trim matters first, because the Passport uses two different 20-inch radial sizes across EX-L, Sport, Elite, and Touring versions.

2021 Honda Trucks Passport EX-L
The 2021 Honda Trucks Passport EX-L uses the 245/50R20 radial size on a 20-inch wheel. That keeps tire selection focused on choosing the correct modern metric replacement and confirming the actual wheel setup if the vehicle has seen any tire or wheel changes.
The 2021 Honda Trucks Passport Elite uses the 265/45R20 radial size on a 20-inch wheel. Tire selection for this sub-model starts with that wider metric fitment, then moves to checking wheel compatibility, condition, and clearance on the vehicle as equipped.
The 2021 Honda Trucks Passport Sport uses the 245/50R20 radial size on a 20-inch wheel. That makes the buying decision straightforward as long as the Passport still has the correct wheels and has not been altered with a different wheel or suspension setup.
The 2021 Honda Trucks Passport Touring uses the 265/45R20 radial size on a 20-inch wheel. The key is staying with that sub-model-specific metric radial fitment and verifying that the current wheels match the intended replacement size before mounting new tires.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Common questions for the 2021 Honda Trucks Passport usually come down to identifying the right 20-inch tire size by sub-model, understanding the metric sizing formats, and checking wheel, suspension, and maintenance details before putting the vehicle back on the road.
Tire Size & Fitment
What tire size fits a 2021 Honda Trucks Passport?
The 2021 Honda Trucks Passport uses two tire sizes: 245/50R20 and 265/45R20. EX-L and Sport models use 245/50R20, while Elite and Touring models use 265/45R20. Both are radial tires designed for 20-inch wheels, so the correct size depends on the trim rather than on a separate bias-ply or radial decision.
The practical step is to confirm the exact sub-model and then verify the wheel size already on the vehicle. A Passport with replacement wheels, prior tire changes, or suspension modifications may need extra attention to width and clearance before choosing between the two metric sizes.
What size rim does a 2021 Honda Trucks Passport use?
The 2021 Honda Trucks Passport uses a 20-inch rim diameter with both of its primary tire sizes. Whether the vehicle takes 245/50R20 or 265/45R20, the final number in the size code points to a 20-inch wheel, and that matches the rim diameter used across the covered sub-models.
Rim diameter is only part of the fitment picture, so it is still smart to check the actual wheel on the vehicle before replacing tires. Wheel width and any aftermarket wheel change can affect how a given tire sits and whether the replacement remains appropriate for the Passport’s current setup.
Why does the 2021 Honda Trucks Passport have more than one tire size?
The 2021 Honda Trucks Passport has more than one tire size because fitment changes by sub-model. EX-L and Sport use 245/50R20, while Elite and Touring use 265/45R20. Both sizes are radial and both fit 20-inch wheels, but they are not the same overall specification.
That means the first decision is not choosing between two interchangeable sizes, but identifying which trim the vehicle is. Once the sub-model is confirmed, compare the replacement tire to the Passport’s actual wheels and current setup so the new tires match the vehicle as equipped.
Choosing the Right Tire
What should I consider when choosing a 245/50R20 tire for a 2021 Honda Trucks Passport?
A 245/50R20 tire for a 2021 Honda Trucks Passport should match the EX-L or Sport fitment and the vehicle’s 20-inch wheel setup. The main factors are staying with the correct size, confirming radial construction, and making sure the replacement suits the wheel dimensions and the way the Passport is used.
Selection becomes more straightforward once the trim is confirmed, but it is still worth checking for any wheel replacement or suspension alteration. A Passport used mostly for daily driving may call for a different emphasis than one that sees heavier cargo duty, longer highway trips, or occasional rougher-road use.
What should I consider when choosing a 265/45R20 tire for a 2021 Honda Trucks Passport?
A 265/45R20 tire belongs on 2021 Honda Trucks Passport Elite and Touring models, so trim verification comes first. After that, the key points are matching the 20-inch wheel, keeping the correct metric size, and selecting a radial tire that works with the vehicle’s present wheel and suspension setup.
Because this is the wider of the two Passport sizes, wheel condition and clearance deserve a close look before replacement. The right choice should reflect how the vehicle is actually driven, while still respecting the sub-model-specific fitment and avoiding assumptions based only on the shared 20-inch rim diameter.
How do I choose between the available tire sizes for a 2021 Honda Trucks Passport?
Choosing between the available tire sizes for a 2021 Honda Trucks Passport starts with the trim, not personal preference. EX-L and Sport use 245/50R20, while Elite and Touring use 265/45R20. Since both fit 20-inch wheels, the difference is tied to sub-model application rather than to a simple upgrade or downgrade choice.
Once the correct size is established, compare the replacement tire against the wheels currently on the vehicle and inspect for any modifications that may affect fitment. That keeps the decision grounded in the Passport’s actual configuration instead of assuming every 20-inch setup across the lineup is the same.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Honda Trucks Passport?
Yes, modifications can affect tire fitment on a 2021 Honda Trucks Passport even when the tire size appears correct on paper. Aftermarket wheels, suspension changes, lowering, or alignment-related wear can change how a 245/50R20 or 265/45R20 tire sits in the wheel opening and how much clearance it has at full steering lock.
A Passport that has been altered from its original wheel and suspension setup deserves a careful check before new tires are installed. Wheel width, offset, fender clearance, and inner suspension clearance should all be reviewed so the replacement tire matches the vehicle as it sits today.
What should I inspect before driving a 2021 Honda Trucks Passport on new tires?
Before driving a 2021 Honda Trucks Passport on new tires, inspect the wheels for damage, confirm that the size matches the correct sub-model, and make sure inflation is set properly for the installed tires. It is also wise to look over the valve stems, check for any obvious suspension issues, and verify that the tires clear during steering movement.
A short shakedown drive can reveal vibration, pull, or rubbing that deserves attention before normal use. Rechecking pressure after the first miles and watching for uneven wear helps confirm that the new tires are working correctly with the Passport’s alignment, wheel condition, and general chassis health.
How often should tires on a 2021 Honda Trucks Passport be inspected?
Tires on a 2021 Honda Trucks Passport should be inspected regularly, not just when replacement time arrives. Frequent checks for tread wear, cuts, bulges, cracking, punctures, and pressure loss are especially important on a modern crossover that may see a mix of commuting, family use, cargo carrying, and highway travel.
A quick visual inspection every few weeks and a closer look before longer trips is a sensible routine. Uneven wear can point to alignment or suspension problems, while low pressure can affect handling and tire life, so regular inspection helps protect both fitment integrity and day-to-day road use.
