The 2011 Mitsubishi Trucks Endeavor sits in the later era of midsize SUVs, when buyers expected a comfortable highway ride, useful cargo space, and a more substantial stance than a car-based wagon. For owners today, tire selection is less about vintage-style construction and more about matching the exact wheel package the vehicle carries. This Endeavor uses radial tires in either 235/65R17 or 255/55R18, depending on sub-model. That makes wheel diameter the first detail to confirm, followed by the balance you want between everyday road manners and a stock-looking overall stance. Getting the right size starts with identifying whether the SUV is an LS or an SE.
Which Tire Size Is Right for The 2011 Mitsubishi Trucks Endeavor
Two tire sizes apply to the 2011 Mitsubishi Trucks Endeavor, and the difference follows sub-model and wheel diameter. The LS uses a 17-inch setup with 235/65R17, while the SE uses an 18-inch setup with 255/55R18. Before choosing a tire, confirm which sub-model you have and verify the actual wheel diameter on the vehicle, especially if the SUV has ever received replacement wheels.
In 235/65R17, the 235 is the tire's nominal width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. This is a modern radial size suited to the Endeavor's 17-inch wheel package and is the primary fitment for the LS sub-model. Its proportions keep the overall tire height close to the larger-wheel alternative while using a slightly taller sidewall. Choose this size when the vehicle is equipped with the correct 17-inch wheels and you want to stay with the intended LS fitment.
In 255/55R18, the 255 is the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 18 is the required rim diameter in inches. This size belongs to the Endeavor's 18-inch wheel package and applies to the SE sub-model. Compared with the 17-inch option, it uses a wider tire on a larger wheel while maintaining a very similar overall diameter. Use this size when the SUV has the proper 18-inch wheels and you want to preserve the fitment intended for the SE configuration.
Fitment changes between Endeavor sub-models, so the correct tire depends on identifying the exact version of the vehicle. The key difference is wheel diameter, with one size tied to the LS and another tied to the SE.

2011 Mitsubishi Trucks Endeavor LS
The 2011 Mitsubishi Trucks Endeavor LS uses the 235/65R17 radial tire size. Tire selection for the LS starts with confirming the 17-inch wheel package, then choosing a replacement that maintains the intended dimensions and road-use character of that setup.
The 2011 Mitsubishi Trucks Endeavor SE uses the 255/55R18 radial tire size. For the SE, the main fitment step is verifying the 18-inch wheel diameter so the replacement tire matches the wider, lower-profile wheel-and-tire package used on this sub-model.
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
These FAQs focus on the exact tire sizes used on the 2011 Mitsubishi Trucks Endeavor, how LS and SE fitment differs, what the size codes mean, and what to inspect before putting the SUV back into regular road use.
Tire Size & Fitment
What tire size fits a 2011 Mitsubishi Trucks Endeavor?
The 2011 Mitsubishi Trucks Endeavor uses two tire sizes, and the correct one depends on sub-model. The LS uses 235/65R17 radial tires, while the SE uses 255/55R18 radial tires. Both are modern metric radial sizes, but they are tied to different wheel diameters.
Choosing between them is not a styling decision alone, because each size belongs to a different wheel package. Check the sub-model and then confirm the actual wheel diameter on the vehicle before ordering tires, especially if the Endeavor has had replacement wheels or prior owner modifications.
What size rim does a 2011 Mitsubishi Trucks Endeavor use?
A 2011 Mitsubishi Trucks Endeavor uses either a 17-inch or 18-inch rim, depending on sub-model. The LS is paired with a 17-inch wheel and 235/65R17 tires, while the SE uses an 18-inch wheel with 255/55R18 tires.
Wheel diameter should be verified before selecting tires because a 17-inch tire cannot mount on an 18-inch rim, and the reverse is also true. Looking at the current sidewall size is helpful, but checking the wheel itself is the safer step if the SUV may have been altered from its original setup.
Do all 2011 Mitsubishi Trucks Endeavor sub-models use the same tire size?
No, the 2011 Mitsubishi Trucks Endeavor does not use the same tire size across all sub-models. The LS uses 235/65R17, while the SE uses 255/55R18. Both are radial tires, but they are not the same size and they do not use the same rim diameter.
That difference matters because tire selection starts with identifying the exact sub-model or confirming the wheel package currently on the SUV. Even though the two sizes have very similar overall diameter, they belong to different wheel setups, so the correct match depends on the wheels actually installed.
Choosing the Right Tire
What should I consider when choosing a 235/65R17 tire for a 2011 Mitsubishi Trucks Endeavor?
A 235/65R17 tire belongs on the 2011 Mitsubishi Trucks Endeavor LS with its 17-inch wheel setup. The main considerations are staying with the correct size, confirming the tire is built for the same rim diameter, and choosing a replacement suited to how the SUV is actually driven on the road today.
Beyond the size itself, check the tire's overall dimensions against the existing setup and make sure the wheel has not been changed to another diameter. Buyers also benefit from considering ride preference, tread style, and whether the goal is a stock-style replacement or a more updated everyday-use tire.
What should I consider when choosing a 255/55R18 tire for a 2011 Mitsubishi Trucks Endeavor?
A 255/55R18 tire is the fitment used on the 2011 Mitsubishi Trucks Endeavor SE with 18-inch wheels. The first requirement is confirming that the SUV still has the proper 18-inch rims, since this size is designed for a different wheel package than the 17-inch LS setup.
After wheel diameter is confirmed, compare the replacement tire's dimensions and intended road use so the wider, lower-profile setup remains consistent. It also helps to inspect the current wheels for prior changes, because aftermarket wheel swaps can alter the width and overall stance even when the sidewall size looks correct.
How do I choose between the available tire sizes for a 2011 Mitsubishi Trucks Endeavor?
The correct choice is determined by the vehicle's sub-model and wheel diameter, not by personal preference alone. A 2011 Mitsubishi Trucks Endeavor LS uses 235/65R17, while an SE uses 255/55R18. Both are radial sizes, but each one is matched to a specific factory wheel package.
Start by identifying whether the SUV is an LS or SE, then verify the wheel diameter currently on the vehicle. If the Endeavor has ever had wheels replaced, rely on the actual wheel size rather than assumptions, because using the wrong tire size for the wheel can create mounting and fitment problems.
Restoration & Appearance
Does correct tire fitment matter for a 2011 Mitsubishi Trucks Endeavor restoration?
Yes, correct tire fitment matters because the 2011 Mitsubishi Trucks Endeavor used different wheel-and-tire packages by sub-model. An LS restored with 235/65R17 tires presents differently than an SE restored with 255/55R18 tires, even though their overall tire height is very close.
A restoration-minded owner should confirm the sub-model and retain the wheel diameter that belongs with it before choosing replacement tires. That helps preserve the intended proportions of the SUV and avoids mixing LS and SE fitment details in a way that changes the vehicle's original visual balance.
Which tire should I choose for a period-style 2011 Mitsubishi Trucks Endeavor?
A period-style choice for a 2011 Mitsubishi Trucks Endeavor starts with using the correct modern metric radial size for the specific sub-model. That means 235/65R17 for the LS or 255/55R18 for the SE, with the proper matching wheel diameter in place.
For an SUV of this era, a period-appropriate look usually comes from maintaining the original size relationship rather than switching to a dramatically different profile. Keeping the correct size preserves the Endeavor's intended stance, while checking the actual wheel package ensures the appearance remains consistent with the sub-model.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Mitsubishi Trucks Endeavor?
Yes, modifications can affect tire fitment on a 2011 Mitsubishi Trucks Endeavor. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change the clearance available for either 235/65R17 or 255/55R18, even when the tire size itself looks close to the intended specification.
A modified SUV should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and suspension movement before replacing tires. That extra step matters because LS and SE setups use different rims, and prior changes can blur the line between original sub-model fitment and the current configuration.
What should I inspect before driving a 2011 Mitsubishi Trucks Endeavor on new tires?
Before driving a 2011 Mitsubishi Trucks Endeavor on new tires, inspect the wheels for damage, confirm lug hardware is correct, and make sure the installed tire size matches the vehicle's wheel diameter and sub-model. It also helps to check alignment condition and look for any signs of suspension wear.
Tire pressure should be set correctly, and the tires should be rechecked after the first miles of use for air loss or contact issues. A quick look at steering clearance, fender clearance, and any rubbing points is especially important if the Endeavor has replacement wheels or a history of suspension changes.
How often should tires on a 2011 Mitsubishi Trucks Endeavor be inspected?
Tires on a 2011 Mitsubishi Trucks Endeavor should be inspected regularly, not just when tread looks low. Frequent checks for uneven wear, cuts, bulges, sidewall damage, and air-pressure loss are important on any SUV, especially one that may see a mix of city driving, highway use, and periods of lower mileage.
A monthly visual inspection is a sensible routine, with added attention before longer trips or after striking potholes or road debris. Owners should also watch for changes in ride feel or steering behavior, since those can point to alignment, inflation, or tire-condition issues before they become more serious.
