The 2009 Saturn Trucks Outlook arrived as a full-size crossover built for families who needed three-row space, carlike road manners, and a more refined alternative to a traditional truck-based SUV. In that role, wheel and tire choice affects both the vehicle’s stance and the way it fills the wheel openings. The 2009 Saturn Trucks Outlook uses two primary radial tire sizes, 255/65R18 and 255/55R20, depending on sub-model and wheel setup. That means the main fitment decision is confirming whether the vehicle is on 18-inch or 20-inch wheels, then choosing the right tire within that size. For a clean replacement, appearance, wheel compatibility, and actual vehicle configuration all matter.
Which Tire Size Is Right for The 2009 Saturn Trucks Outlook
The 2009 Saturn Trucks Outlook uses two primary tire sizes, and the right one depends on sub-model and wheel diameter. Both are radial metric sizes, but one fits an 18-inch wheel and the other fits a 20-inch wheel. Before choosing a tire, confirm whether the Outlook is an XE or XR and verify the wheel diameter actually on the vehicle, especially if wheels have ever been changed.
A 255/65R18 tire uses a 255-millimeter section width, a 65-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2009 Saturn Trucks Outlook, this is one of the primary fitments and it appears on the XE as well as some XR configurations. Because it is a modern metric radial size, replacement choices usually focus less on vintage-style presentation and more on confirming the correct wheel diameter and maintaining the intended overall tire proportions. This size is the right starting point when the Outlook is equipped with 18-inch wheels.
A 255/55R20 tire keeps the same 255-millimeter nominal width but uses a lower 55-series profile on a 20-inch rim. On the 2009 Saturn Trucks Outlook, this size is associated with XR configurations using the larger wheel setup. Its dimensions are very close in overall diameter to the 18-inch fitment, so the main distinction is wheel diameter rather than a dramatic change in tire height. This size should be evaluated when the vehicle is riding on factory-style or aftermarket 20-inch wheels and the tire selection needs to match that setup.
Sub-model fitment matters on the 2009 Saturn Trucks Outlook because tire size is tied to wheel setup. The XE stays with one size, while the XR can appear with either of the two primary radial sizes, making wheel confirmation an important step before replacement.

2009 Saturn Trucks Outlook XE
The 2009 Saturn Trucks Outlook XE uses the 255/65R18 radial size. Tire selection for an XE is usually straightforward, with the main job being to confirm the 18-inch wheel and choose a replacement tire that suits the vehicle’s current use and condition.
The 2009 Saturn Trucks Outlook XR can use either 255/65R18 or 255/55R20, depending on the wheel package on the vehicle. That makes the XR the version where checking the actual wheel diameter before ordering tires is especially important, particularly if the vehicle has seen wheel changes over time.
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
The most common tire questions for a 2009 Saturn Trucks Outlook center on the two correct sizes, 18-inch versus 20-inch wheel fitment, and how to choose the right radial tire once the exact XE or XR configuration is confirmed.
Tire Size & Fitment
What tire size fits a 2009 Saturn Trucks Outlook?
The 2009 Saturn Trucks Outlook uses two primary tire sizes: 255/65R18 and 255/55R20. Both are radial sizes, and the correct one depends on the sub-model and wheel setup. The XE uses 255/65R18, while the XR can be equipped with either 255/65R18 or 255/55R20.
The practical next step is to verify the wheel diameter on the vehicle before choosing a tire. An Outlook with 18-inch wheels needs the 18-inch size, and an Outlook with 20-inch wheels needs the 20-inch size. That check matters even more if the vehicle has had replacement wheels installed at some point.
What size rim does a 2009 Saturn Trucks Outlook use?
A 2009 Saturn Trucks Outlook uses either an 18-inch or 20-inch rim, depending on the tire size and configuration. The 255/65R18 tire fits an 18-inch rim, while the 255/55R20 tire fits a 20-inch rim. Both sizes are used on this model year, so there is not one single rim diameter across every Outlook.
Checking the rim itself is more important than guessing from trim alone, especially on an XR. Tire sidewall markings and a direct wheel measurement can help confirm what is on the vehicle now. Once rim diameter is confirmed, the buyer can focus on the correct tire size, load suitability, and overall condition of the wheels.
Do all 2009 Saturn Trucks Outlook sub-models use the same tire size?
No, not all 2009 Saturn Trucks Outlook sub-models use the same tire size. The XE uses 255/65R18, while the XR can use either 255/65R18 or 255/55R20. That means the Outlook range shares one size in some cases, but not across every configuration.
This matters because the XR does not point to one automatic replacement size without checking the actual wheels. A buyer replacing tires on an XE usually has a simpler path, while an XR owner should confirm whether the vehicle has 18-inch or 20-inch wheels. Matching the tire to the wheel is the first fitment decision.
Choosing the Right Tire
What should I consider when choosing a 255/65R18 tire for a 2009 Saturn Trucks Outlook?
A 255/65R18 tire for a 2009 Saturn Trucks Outlook should match the vehicle’s 18-inch wheel setup and maintain the intended size for that configuration. This size appears on the XE and on some XR models, so the basic fitment question is usually straightforward once the wheel diameter is confirmed.
From there, compare the tire’s overall suitability for how the Outlook is used, including family road use, seasonal conditions, and the condition of the wheels and suspension. It also helps to inspect for uneven wear on the old tires, since that can point to alignment or suspension issues that should be corrected before new tires go into service.
What should I consider when choosing a 255/55R20 tire for a 2009 Saturn Trucks Outlook?
A 255/55R20 tire is the correct choice for a 2009 Saturn Trucks Outlook only when the vehicle is equipped with 20-inch wheels. On this model year, that size is associated with XR configurations. Its overall diameter is very close to the 18-inch fitment, but the wheel diameter is different, so correct matching still matters.
Selection should start with confirming the wheel size actually on the vehicle, then checking for clearance issues if the Outlook has aftermarket wheels or suspension changes. Because this is a lower-profile fitment on a larger wheel, it is also wise to inspect the wheel condition carefully for bends, curb damage, or bead-seat corrosion before mounting new tires.
How do I choose between the available tire sizes for a 2009 Saturn Trucks Outlook?
Choosing between the available tire sizes for a 2009 Saturn Trucks Outlook is not a matter of preference alone, because the size is tied to wheel diameter. The vehicle uses either 255/65R18 or 255/55R20, and the correct choice depends on whether the Outlook has 18-inch or 20-inch wheels.
Once the wheel diameter is confirmed, the decision becomes simpler: use the size that matches the wheel and the specific XE or XR setup. It is smart to look at all four tires and wheels rather than relying on memory, since some vehicles change hands with non-original wheel packages. That quick check prevents ordering a tire that cannot be mounted.
Restoration & Appearance
Does correct tire fitment matter for a 2009 Saturn Trucks Outlook restoration?
Yes, correct tire fitment still matters on a 2009 Saturn Trucks Outlook restoration or preservation project, even though this is a newer vehicle than a traditional collector car. The right size keeps the wheel-to-tire relationship consistent with the vehicle’s intended setup, whether that means 255/65R18 on 18-inch wheels or 255/55R20 on 20-inch wheels.
Appearance is part of that decision, but so is proportion and stance. A size mismatch can change how the Outlook sits and can complicate wheel and clearance relationships. Owners aiming for a cleaner stock-style presentation should verify the original wheel package on the specific vehicle before replacing tires or sourcing another set of wheels.
How does tire size affect the appearance of a 2009 Saturn Trucks Outlook?
Tire size affects the appearance of a 2009 Saturn Trucks Outlook mainly through wheel diameter and sidewall profile. The 255/65R18 setup places a taller sidewall around an 18-inch wheel, while the 255/55R20 uses a lower profile on a 20-inch wheel. Both sizes are close in overall diameter, but they present the vehicle differently.
That means visual preference should follow confirmed fitment rather than guesswork. An owner trying to preserve the vehicle’s original look should first determine which wheel package belongs on that particular XE or XR. Once that is settled, the tire choice can support either a more substantial sidewall appearance or the cleaner look of the larger wheel package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Saturn Trucks Outlook?
Yes, modifications can affect tire fitment on a 2009 Saturn Trucks Outlook. Aftermarket wheels, changes in wheel width or offset, suspension alterations, and ride-height changes can all influence how a 255/65R18 or 255/55R20 tire sits in the wheel opening. Even when the basic tire size looks correct, the total setup can change clearance behavior.
That is why a modified Outlook should be checked for steering clearance, fender clearance, and any signs of rubbing before finalizing a replacement tire. Looking at the current wheel markings and inspecting the suspension can prevent surprises. Small setup differences often matter more than the size code alone when a vehicle has been altered.
What should I inspect before driving a 2009 Saturn Trucks Outlook on new tires?
Before driving a 2009 Saturn Trucks Outlook on new tires, inspect the wheels for damage, confirm that all four tires are the correct size for the wheel setup, and make sure the valves and bead areas are in good condition. It is also worth checking alignment-related wear patterns on the old tires before they are discarded.
A short road test should be paired with another look for air loss, vibration, or any contact inside the wheel wells. Tire pressure should be set appropriately for the vehicle’s use, and lug hardware should be checked after installation. Catching a wheel or suspension issue early helps the new tires wear more evenly and perform as intended.
What should I check before a longer drive in a 2009 Saturn Trucks Outlook?
Before a longer drive in a 2009 Saturn Trucks Outlook, check tire pressure, tread condition, sidewall condition, and any signs of cuts, bulges, or irregular wear. It is also smart to confirm that all four tires match the vehicle’s actual wheel setup, since this model year can use either 18-inch or 20-inch fitment.
A longer trip places more importance on overall vehicle condition, so wheel balance, alignment, and suspension health deserve attention too. Uneven shoulder wear or repeated pressure loss should be addressed before heading out. On a vehicle that has spent time parked, age and storage condition can matter almost as much as remaining tread depth.
