The 2018 Honda Trucks Ridgeline blends modern pickup utility with the road manners and everyday drivability that helped set it apart from more traditional body-on-frame trucks. For owners who use a Ridgeline as a practical daily driver, light-duty hauler, or long-distance highway truck, tire choice affects ride quality, wet-weather confidence, and overall stance more than almost any other routine replacement item. This Ridgeline uses one primary tire size, 245/60R18, in radial construction. That keeps fitment straightforward, while still leaving room to compare tire style, tread character, and overall use. The key is matching that size to the truck's actual wheels and intended driving conditions.
Which Tire Size Is Right for The 2018 Honda Trucks Ridgeline
The 2018 Honda Trucks Ridgeline uses one primary tire size: 245/60R18, a radial tire built for an 18-inch rim. That same size is used across the covered Ridgeline sub-models, so the main decision is not identifying between multiple fitments, but choosing the right 245/60R18 tire for the truck's wheels, condition, and intended road use.
Fit(s): Black Edition, RT, RTL, RTL-E, RTL-T, and Sport
Construction: Radial|Rim: 18 in
A 245/60R18 size uses a metric sizing system: 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 2018 Honda Trucks Ridgeline, this is a modern radial fitment suited to the truck's contemporary on-road and light-duty pickup role. The format will be familiar to buyers replacing everyday truck or crossover tires, making comparison easier across available designs and intended uses. The right choice comes down to staying with the proper size while confirming wheel condition and any changes from the original setup.
Tire fitment is straightforward across the covered 2018 Honda Trucks Ridgeline sub-models, with the same 245/60R18 radial size used throughout. Checking the exact trim still matters, but the buying decision is mainly about selecting the right tire within that shared size rather than sorting through multiple fitments.

Frequently Asked Questions
These Ridgeline tire FAQs focus on the 245/60R18 fitment, 18-inch rim compatibility, trim-level consistency, replacement-tire selection, and the inspections worth making before putting a modern pickup back into regular road use.
Tire Size & Fitment
What tire size fits a 2018 Honda Trucks Ridgeline?
The 2018 Honda Trucks Ridgeline uses a 245/60R18 tire size in radial construction. That size appears across the covered Ridgeline trims, making it the primary fitment for this model year and vehicle line.
Even with one shared size, it is still smart to confirm that the truck is wearing the correct 18-inch wheels and has not been changed with aftermarket wheels or suspension parts. A used Ridgeline may look stock while carrying a different wheel package, so matching the replacement tire to the actual wheel on the truck is the practical first step.
What size rim does a 2018 Honda Trucks Ridgeline use?
The primary tire fitment for the 2018 Honda Trucks Ridgeline is built around an 18-inch rim diameter. That rim diameter matches the 245/60R18 tire size used on the covered sub-models.
Rim diameter is only one part of the fitment picture, so it helps to confirm the full wheel setup before ordering tires. Width, offset, and any wheel changes made by a previous owner can influence how a 245/60R18 sits on the truck, especially if the Ridgeline has been altered for appearance or utility use.
Do all 2018 Honda Trucks Ridgeline sub-models use the same tire size?
Yes. The covered 2018 Honda Trucks Ridgeline sub-models all use the same primary tire size, 245/60R18, in radial construction. That includes Black Edition, RT, RTL, RTL-E, RTL-T, and Sport.
Shared sizing makes replacement easier because the first question is usually no longer trim-specific fitment. The more useful check is whether the truck still carries its correct 18-inch wheels and whether any wheel, suspension, or ride-height changes have altered the clearance or overall tire choice compared with a standard Ridgeline setup.
Choosing the Right Tire
What should I consider when choosing a 245/60R18 tire for a 2018 Honda Trucks Ridgeline?
Start with the correct size, 245/60R18, and confirm that the truck uses the proper 18-inch wheels. Since this Ridgeline uses a modern radial fitment, the main selection factors are the tire's intended driving role, road manners, seasonal use, and how the truck is actually driven.
A Ridgeline that spends most of its time on pavement may call for a different replacement emphasis than one used regularly for hauling, bad-weather commuting, or rougher access roads. It also helps to compare the condition of the wheels, inspect for uneven wear that might point to alignment or suspension issues, and choose a tire that suits the truck's real use rather than its badge.
How do I choose between the available 245/60R18 tires for a 2018 Honda Trucks Ridgeline?
Choosing between 245/60R18 tires for a 2018 Honda Trucks Ridgeline comes down to use, wheel compatibility, and overall vehicle condition. Since the fitment itself is straightforward, the difference is usually found in the type of driving the truck sees and the kind of replacement behavior the owner wants.
Some owners prioritize smooth highway manners and quiet road use, while others need a tire better suited to wet roads, light cargo duty, or mixed pavement conditions. Looking at tread wear patterns on the current tires can also be useful, since that may reveal whether the next set should be chosen alongside an alignment check, suspension inspection, or wheel-condition review.
What rim-fitment details should I compare when choosing 2018 Honda Trucks Ridgeline tires?
The first rim-fitment detail is diameter, and the 2018 Honda Trucks Ridgeline's primary size uses an 18-inch wheel. Beyond that, the important wheel checks are whether the wheel width is suitable for the tire, whether offset has changed, and whether the truck still has its intended wheel package.
Those details matter most on used trucks, because aftermarket wheels can change how a 245/60R18 tire sits within the fender opening and during full steering travel. A careful look at present clearance, wheel condition, and any signs of rubbing or uneven tire wear will help narrow the right replacement choice before mounting new tires.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Honda Trucks Ridgeline restoration or clean original-style presentation?
Yes. Even on a newer truck like the 2018 Honda Trucks Ridgeline, correct tire fitment plays a major role in preserving the vehicle's intended stance, wheel proportion, and overall appearance. Staying with the proper 245/60R18 size helps maintain the balanced look the truck was designed around.
That matters whether the goal is a clean original-style presentation or simply avoiding the oversized or undersized look that can come from casual substitutions. Owners focused on appearance should also verify that the wheels themselves are correct for the truck's setup, since the right tire size can still look off if paired with a changed wheel package.
Which tire should I choose for a clean, original-style 2018 Honda Trucks Ridgeline?
A clean, original-style approach starts by keeping the correct 245/60R18 radial size on the 2018 Honda Trucks Ridgeline. That preserves the truck's intended overall proportion and keeps the visual relationship between tire, wheel, and body closer to a standard Ridgeline presentation.
From there, the best choice is usually the tire that looks appropriately at home on the truck without pushing it toward an overly aggressive or oversized appearance. Matching the replacement to the actual wheel setup and avoiding unnecessary size changes will do more for an original-style result than chasing a different size simply for visual impact.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Honda Trucks Ridgeline?
Yes. Modifications can change tire fitment on a 2018 Honda Trucks Ridgeline even when the replacement tire remains 245/60R18. Wheel width, offset, suspension changes, lowering, and ride-height adjustments can all affect clearance during steering and normal suspension travel.
That is why a modified Ridgeline should be checked at the truck, not just by the factory-style size printed on the sidewall. Looking for rubbing marks, confirming wheel dimensions, and paying attention to fender and inner-clearance space will help prevent surprises when replacing tires on a truck that no longer sits exactly as originally configured.
What should I inspect before driving a 2018 Honda Trucks Ridgeline on new tires?
Before driving a 2018 Honda Trucks Ridgeline on new tires, inspect wheel condition, verify tire pressure, and make sure the tires are the correct 245/60R18 size for the truck's actual wheel setup. It is also wise to check for suspension wear, alignment issues, and any signs of prior rubbing.
A fresh set of tires can highlight existing problems that older worn tires were masking. Uneven wear on the previous set, steering pull, vibration, or visible component wear should be addressed early so the new tires start on a sound platform rather than being exposed immediately to the same conditions that shortened the life of the old set.
How often should tires on a 2018 Honda Trucks Ridgeline be inspected?
Tires on a 2018 Honda Trucks Ridgeline should be checked regularly, not just when replacement time arrives. Frequent inspection helps catch uneven wear, air loss, punctures, cuts, bulges, and sidewall damage before they become more serious road-use problems.
Routine checks matter even more on a truck that sees changing duty, such as commuting one week and hauling or longer trips the next. Looking over the tires during pressure checks, service visits, or before a highway drive makes it easier to spot issues early and helps confirm that the 245/60R18 fitment is still wearing evenly across all four corners.
