The 2021 Honda Trucks Ridgeline sits in a modern niche between a traditional midsize pickup and a more road-focused daily driver, which is part of its appeal for owners who want truck utility without giving up everyday comfort. That balance matters when it comes time to replace tires, because the tire choice affects ride quality, appearance, and year-round usability. This Ridgeline uses a 245/60R18 radial tire across the covered lineup. The decision is less about sorting through multiple fitment sizes and more about choosing the right tread and product character within the correct size. For the best result, start with proper 18-inch wheel fitment and match the tire to how the truck is actually used.
Which Tire Size Is Right for The 2021 Honda Trucks Ridgeline
The 2021 Honda Trucks Ridgeline uses one primary tire size: 245/60R18, and it is a radial fitment for an 18-inch rim. That same size is used across the covered sub-models, so the main decision is not which size fits, but which 245/60R18 tire best suits your driving needs, wheel setup, and overall truck use.
A 245/60R18 tire uses a metric sizing format: 245 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2021 Honda Trucks Ridgeline, this radial size supports the truck's everyday blend of comfort, handling, and utility on an 18-inch wheel. Because every covered sub-model uses this same size, selection comes down to choosing the right tire type and overall use profile rather than sorting through multiple fitments. It is also worth confirming that the truck still has the correct wheel size if aftermarket wheels have been installed.
Tire fitment is straightforward across the covered 2021 Honda Trucks Ridgeline lineup, because each sub-model uses the same 245/60R18 radial size. Checking the exact trim still matters, but the tire-size decision remains consistent whether the truck is more comfort-oriented or more appearance-focused.

2021 Honda Trucks Ridgeline Black Edition
The 2021 Honda Trucks Ridgeline Black Edition uses the same 245/60R18 radial tire size as the other covered trims. That keeps tire selection simple and shifts the focus toward choosing a tire that matches the truck's wheel setup, daily driving role, and overall appearance preferences.
The 2021 Honda Trucks Ridgeline RTL uses 245/60R18 radial tires. Since fitment does not change here, the practical decision is selecting a tire in the correct size that suits the truck's road use, replacement goals, and any wheel changes made over time.
The 2021 Honda Trucks Ridgeline RTL-E also uses the 245/60R18 radial size. With the primary fitment staying the same, the next step is verifying the current 18-inch wheel setup and choosing a tire that matches how the truck is driven and maintained.
The 2021 Honda Trucks Ridgeline Sport uses the same 245/60R18 radial tire size as the rest of the covered Ridgeline range. That means the key tire decision centers on product choice within the proper size, along with confirming that the truck still carries the intended 18-inch wheels.
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 Ridgeline usually center on the 245/60R18 tire size, 18-inch wheel fitment, trim-level consistency, and what to inspect before putting replacement tires into regular road use.
Tire Size & Fitment
What tire size fits a 2021 Honda Trucks Ridgeline?
The 2021 Honda Trucks Ridgeline uses a 245/60R18 tire size. This is a radial fitment, and it is the primary size used across the covered Ridgeline sub-models, including Sport, RTL, RTL-E, and Black Edition.
That makes size selection fairly straightforward, but the truck should still be checked for any wheel changes made by a previous owner. A Ridgeline that still has its intended 18-inch wheels can stay focused on choosing the right 245/60R18 tire, while a modified truck needs wheel size and clearance confirmed before replacement.
What size rim does a 2021 Honda Trucks Ridgeline use?
The 2021 Honda Trucks Ridgeline uses an 18-inch rim with its 245/60R18 tire size. In that size code, the final 18 identifies the wheel diameter the tire is built to mount on.
Wheel diameter should be confirmed before purchasing tires, especially if the truck has aftermarket wheels or a second wheel-and-tire set. Tire size must match the actual rim diameter, and it is also smart to verify wheel width, current tire clearance, and overall condition before mounting a new set.
Do all 2021 Honda Trucks Ridgeline sub-models use the same tire size?
Yes, the covered 2021 Honda Trucks Ridgeline sub-models all use the same 245/60R18 radial tire size. Black Edition, RTL, RTL-E, and Sport each share that same primary fitment.
Shared sizing simplifies replacement, because the main question is not trim-specific tire size but whether the truck still has the intended wheel setup. It also means buyers can concentrate on selecting the right tire character for commuting, mixed use, or seasonal driving without having to sort through multiple factory size combinations.
Choosing the Right Tire
What should I consider when choosing a 245/60R18 tire for a 2021 Honda Trucks Ridgeline?
Start with the correct 245/60R18 size, because that is the primary fitment for the 2021 Honda Trucks Ridgeline. After that, the main considerations are the truck's actual wheel setup, how it is driven, and whether it is used mostly for commuting, general utility, or mixed road conditions.
A well-chosen replacement should suit the Ridgeline's everyday balance of comfort and truck usefulness without straying from the proper size. It helps to verify the 18-inch wheel diameter, inspect for suspension or wheel modifications, and compare tire features in the context of road use rather than choosing only by appearance.
How do I choose between available 245/60R18 tires for a 2021 Honda Trucks Ridgeline?
Choosing between 245/60R18 tires for a 2021 Honda Trucks Ridgeline starts with matching the truck's intended use. A daily-driven truck may call for one type of road manners, while a Ridgeline that sees more varied weather or light-duty hauling may lead you to compare different tire priorities within the same size.
It is also worth checking the vehicle itself before deciding. Tire age, current wear patterns, alignment condition, and any wheel changes can influence which replacement makes the most sense, and those practical factors matter more than simply picking another tire with the same size molded on the sidewall.
What rim-fitment details should I compare when choosing tires for a 2021 Honda Trucks Ridgeline?
The first rim-fitment detail to confirm is diameter, because the 2021 Honda Trucks Ridgeline uses an 18-inch wheel with its 245/60R18 tire size. The tire and wheel must match in diameter before any other comparison matters.
Wheel width, overall wheel condition, and any non-stock wheel changes should also be checked before mounting replacement tires. Those details affect how the tire sits on the wheel and whether there is adequate clearance at full steering lock and through suspension movement, especially on a truck that has been modified from stock.
Restoration & Appearance
Does correct tire fitment matter for a 2021 Honda Trucks Ridgeline restoration or refresh?
Yes, correct tire fitment still matters on a 2021 Honda Trucks Ridgeline, even though this is a modern truck rather than a vintage restoration candidate. Staying with the proper 245/60R18 size helps preserve the intended wheel-to-tire proportion and keeps the truck visually consistent with its original overall stance.
For an appearance-focused refresh, the safest starting point is the correct size on the proper 18-inch rim rather than experimenting with a different diameter. That approach also reduces the chance of unwanted clearance issues and helps keep the truck's look balanced instead of making the wheel opening or sidewall profile appear mismatched.
How does tire selection affect the appearance of a 2021 Honda Trucks Ridgeline?
Tire selection affects how a 2021 Honda Trucks Ridgeline sits visually, even when the size stays at the correct 245/60R18. Sidewall shape, tread character, and the way a tire fills the wheel opening can all influence whether the truck looks more road-oriented, more rugged, or simply more cohesive overall.
Appearance should still be evaluated alongside proper fitment. A tire that looks right on the truck also needs to match the 18-inch wheel, maintain suitable clearance, and suit the Ridgeline's real use, because a visual choice alone does not guarantee the best overall result once the truck is back on the road.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Honda Trucks Ridgeline?
Yes, modifications can affect tire fitment on a 2021 Honda Trucks Ridgeline even when the original size is 245/60R18. Aftermarket wheels, suspension changes, ride-height adjustments, and body alterations can all change the space available for the tire and the way it sits in the wheel opening.
That is why the current setup should be checked before replacing tires. Confirm the actual wheel diameter, inspect wheel width and offset if known, and look for signs of rubbing near the fenders, suspension, or steering components so the next tire choice is based on the truck as it sits today.
What should I inspect before driving a 2021 Honda Trucks Ridgeline on new tires?
Before driving a 2021 Honda Trucks Ridgeline on new tires, inspect the wheels, valve stems, and overall mounting condition, then check inflation pressure and confirm there is no visible interference around the tire. It also helps to look at the truck's alignment history and general suspension condition.
A short initial drive is a good time to watch for vibration, pulling, unusual noise, or contact at full steering lock. Those checks are especially important if the truck has been sitting, has uneven wear on the old tires, or has had wheel or suspension changes since the last tire installation.
How often should tires on a 2021 Honda Trucks Ridgeline be inspected?
Tires on a 2021 Honda Trucks Ridgeline should be inspected regularly rather than only when replacement time arrives. A routine visual check for tread wear, cracking, punctures, bulges, and uneven shoulder wear helps catch issues early, especially on a truck used for commuting, hauling, or changing seasonal conditions.
Pressure should also be checked consistently, because underinflation and overinflation can both affect wear and road manners. Even with the correct 245/60R18 size, a Ridgeline benefits from periodic inspections tied to normal use, longer trips, and any sign that the truck is steering, braking, or riding differently than usual.
