The 2010 Mitsubishi Trucks Endeavor comes from an era when midsize SUVs were expected to balance family use, highway comfort, and a more substantial stance than a passenger car. Its broad, clean styling and car-based road manners make tire choice more than a simple replacement exercise, especially when wheel size changes by trim. On this Endeavor, primary fitment is radial, with 235/65R17 used on the LS and 255/55R18 used on the SE. That means the real decision starts with confirming the exact sub-model and wheel diameter before comparing tire dimensions. Once that is settled, the focus shifts to maintaining the right overall look, ride balance, and fitment clearance.
Which Tire Size Is Right for The 2010 Mitsubishi Trucks Endeavor
The 2010 Mitsubishi Trucks Endeavor uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Both fitments are radial, but the LS uses a 17-inch rim while the SE uses an 18-inch rim, so the first step is confirming which wheels are on the vehicle before selecting a tire.
235/65R17 is a metric radial size in which 235 identifies the nominal section width in millimeters, 65 is the aspect ratio, R designates radial construction, and 17 is the wheel diameter in inches. On the 2010 Mitsubishi Trucks Endeavor, this size belongs to the LS configuration and uses a 17-inch rim. Its sizing points to a balanced, modern SUV fitment rather than a vintage sizing system. Choosing this size starts with confirming that the vehicle still has the correct 17-inch wheel package and that no aftermarket wheel or suspension changes have altered clearance requirements.
255/55R18 is a metric radial size that uses a wider 255-millimeter nominal section width, a 55-series aspect ratio, radial construction, and an 18-inch wheel diameter. On the 2010 Mitsubishi Trucks Endeavor, this size is used on the SE and is tied to the larger 18-inch rim. Compared with older numeric or alphanumeric formats, it is a straightforward modern metric fitment. Selecting this size means verifying that the Endeavor still carries the correct 18-inch wheel setup and checking for adequate clearance if the vehicle has been modified or fitted with replacement wheels.
Fitment changes by sub-model on the 2010 Mitsubishi Trucks Endeavor, so identifying the trim is essential before choosing tires. The LS and SE do not share the same wheel diameter, which makes sub-model confirmation more important than simply matching the vehicle year and model name.

2010 Mitsubishi Trucks Endeavor LS
The 2010 Mitsubishi Trucks Endeavor LS uses the 235/65R17 radial size on a 17-inch wheel. That makes tire selection relatively straightforward once the wheel setup is confirmed, with the main priority being replacement in the correct metric size rather than sorting through multiple primary fitments.
The 2010 Mitsubishi Trucks Endeavor SE uses the 255/55R18 radial size on an 18-inch wheel. Tire selection begins with confirming that the vehicle still has the proper 18-inch wheels, since moving between LS and SE fitments is not simply a matter of choosing a different tire without checking wheel compatibility.
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 2010 Mitsubishi Trucks Endeavor usually center on choosing between the LS and SE tire sizes, confirming the correct rim diameter, and checking fitment carefully if wheels or suspension have been changed.
Tire Size & Fitment
What tire size fits a 2010 Mitsubishi Trucks Endeavor?
The 2010 Mitsubishi Trucks Endeavor uses two primary tire sizes. The LS uses 235/65R17, while the SE uses 255/55R18. Both are radial tire fitments, but they are tied to different wheel diameters, so they are not simply alternate versions of the same setup.
The practical first step is identifying the exact sub-model and confirming which wheels are actually on the vehicle today. An Endeavor that has had replacement wheels installed may no longer match its original trim-based fitment, so checking the tire sidewall, wheel diameter, and vehicle configuration before choosing a replacement helps prevent ordering the wrong size.
What size rim does a 2010 Mitsubishi Trucks Endeavor use?
A 2010 Mitsubishi Trucks Endeavor uses either a 17-inch or 18-inch rim, depending on sub-model. The LS uses the 235/65R17 size on a 17-inch rim, while the SE uses the 255/55R18 size on an 18-inch rim. Both fitments use modern radial sizing.
Rim diameter matters before anything else because a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. Checking the wheel itself is especially important if the Endeavor has changed hands, received aftermarket wheels, or had tires replaced previously without regard to original trim-based fitment.
Do all 2010 Mitsubishi Trucks Endeavor sub-models use the same tire size?
No. The 2010 Mitsubishi Trucks Endeavor LS uses 235/65R17, while the SE uses 255/55R18. That means sub-model fitment is not shared across the full Endeavor range for this year, even though both versions use radial construction.
That difference affects more than the tire alone because each size is tied to a different wheel diameter. A buyer should confirm the trim level and physically verify the current wheel setup before selecting replacement tires, especially on used vehicles where wheels may have been changed from the original LS or SE configuration.
Choosing the Right Tire
What should I consider when choosing a 235/65R17 or 255/55R18 tire for a 2010 Mitsubishi Trucks Endeavor?
Start with the correct trim-based size: 235/65R17 for the LS and 255/55R18 for the SE. After that, focus on matching the tire to the wheel diameter already on the vehicle and keeping the replacement in the proper metric radial size rather than treating the two Endeavor fitments as interchangeable.
Beyond size, compare the tire's overall purpose for how the vehicle is actually used, such as routine road driving, occasional highway travel, or light-duty utility use. It also helps to check the existing wheel condition, the current suspension setup, and any prior modifications so the selected tire works cleanly with the Endeavor's present configuration.
How do I choose between the available 2010 Mitsubishi Trucks Endeavor tire sizes?
The choice is not based on preference alone, because the two sizes belong to different Endeavor sub-models. A 2010 Mitsubishi Trucks Endeavor LS uses 235/65R17, and an SE uses 255/55R18, so the correct selection begins with the vehicle's actual trim and wheel package.
Once the size is confirmed, look at whether the vehicle still carries its intended wheel diameter and whether any aftermarket changes have altered the setup. A used Endeavor can appear stock while wearing a different wheel package, so reading the tire sidewall and measuring the wheel diameter is a more reliable guide than appearance alone.
Why does the 2010 Mitsubishi Trucks Endeavor have more than one tire size?
The 2010 Mitsubishi Trucks Endeavor has more than one tire size because tire fitment changes by sub-model. The LS uses 235/65R17 on a 17-inch rim, while the SE uses 255/55R18 on an 18-inch rim. Both are normal radial fitments, but they belong to different trim-based wheel packages.
That means the correct replacement tire depends on how the vehicle was equipped, not just the model name on the tailgate. Checking the trim level is useful, but verifying the actual wheel diameter on the vehicle is even better, especially when prior owners may have swapped wheels or changed the stance for appearance.
Restoration & Appearance
Does correct tire fitment matter for a 2010 Mitsubishi Trucks Endeavor restoration?
Yes. Even on a newer collector-era SUV, correct tire fitment matters because the 2010 Mitsubishi Trucks Endeavor uses different sizes by sub-model. The LS and SE do not share the same wheel diameter, so using the wrong size can change the vehicle's stance and create unnecessary fitment complications.
A restoration-minded owner should begin with the proper trim-based size and wheel diameter before making any appearance-driven choice. If exact authenticity matters, comparing the vehicle against original owner documentation, window-sticker information, or marque-specific references can help confirm whether the current wheel and tire package matches how that Endeavor was originally equipped.
How does tire size affect the appearance of a 2010 Mitsubishi Trucks Endeavor?
Tire size has a visible effect on a 2010 Mitsubishi Trucks Endeavor because the LS and SE use different wheel diameters and different metric tire proportions. A 235/65R17 and a 255/55R18 can both belong on this model range, but each gives the vehicle a different visual balance based on wheel size and sidewall height.
Owners who care about maintaining the vehicle's intended look should match the tire size to the correct sub-model and wheel package rather than choosing by appearance alone. That approach keeps the SUV closer to its original trim-specific presentation and reduces the chance of creating clearance or wheel-compatibility issues through guesswork.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Mitsubishi Trucks Endeavor?
Yes. Modifications can affect tire fitment on a 2010 Mitsubishi Trucks Endeavor even when the replacement tire matches one of the original sizes. Wheel changes, altered offset, suspension work, lowering, or non-stock ride height can all influence how a 235/65R17 or 255/55R18 sits within the wheel opening.
A modified Endeavor should be checked for wheel diameter, clearance at full steering lock, and any signs that the tire may contact suspension or body components. Looking at the vehicle's current setup is especially important before moving between LS and SE wheel packages, since the two sizes are tied to different rims rather than interchangeable by default.
What should I inspect before driving a 2010 Mitsubishi Trucks Endeavor on new tires?
Before driving a 2010 Mitsubishi Trucks Endeavor on new tires, inspect basic fitment and vehicle condition. Confirm the correct size for the trim, check that the tires are properly seated on the wheels, and look over the rims, valve stems, and visible suspension components for damage or wear that could affect road use.
It also helps to verify inflation pressure, steering clearance, and any signs of rubbing during low-speed turning. A short test drive can reveal vibration, pull, or interference that was not obvious in the shop. Catching those issues early is especially useful on an SUV that may have seen wheel changes or suspension aging over time.
How often should tires on a 2010 Mitsubishi Trucks Endeavor be inspected?
Tires on a 2010 Mitsubishi Trucks Endeavor should be inspected regularly, not just when replacement is overdue. Routine checks should cover tread wear, visible cuts, bulges, irregular wear patterns, sidewall damage, and slow air loss. On an older SUV, those inspections are important even when the vehicle is driven less often than it once was.
Regular inspection also helps confirm that the vehicle is still wearing the correct LS or SE size and that wear is not pointing to wheel, alignment, or suspension issues. Checking the tires before longer drives, seasonal use, or after storage gives a clearer picture of whether the Endeavor is ready for the road.
