The 2005 Lincoln LS came from a period when Lincoln was giving its midsize sport sedan a more driver-focused identity, blending rear-wheel-drive proportions with modern luxury and sharper road manners than many domestic sedans of its time. That matters when choosing tires, because the LS uses two different modern radial sizes depending on trim: 225/55R16 or 235/50R17. The Appearance, Luxury, and Premium models stay with the 16-inch fitment, while Sport and Ultimate models move to a 17-inch setup. Tire selection here is less about vintage-style construction and more about matching the correct size, wheel diameter, and driving character for the exact trim.
Which Tire Size Is Right for The 2005 Lincoln LS
The 2005 Lincoln LS uses two primary tire sizes, and the correct choice depends first on the exact sub-model and wheel diameter. Appearance, Luxury, and Premium trims use a 16-inch radial fitment, while Sport and Ultimate trims use a 17-inch radial fitment. Before comparing tires, confirm which trim the car is and whether it still has the original wheel size, since that determines which size belongs on the car.
225/55R16 is a modern metric radial size in which 225 identifies the section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 2005 Lincoln LS, this size belongs to the 16-inch wheel setup used on certain trims and supports the car's modern sedan character rather than a vintage bias-ply presentation. Available choices in this size center on BFGoodrich blackwall performance-oriented offerings in the g-Force Sport Comp 2 and g-Force Comp 2 AS series. This is the size to evaluate when the car retains the 16-inch wheel package and the goal is proper fitment with contemporary radial construction.
235/50R17 is a modern metric radial size where 235 is the nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. For the 2005 Lincoln LS, this size applies to the 17-inch setup used on specific trims, giving the buyer a distinct fitment path from the 16-inch package. Product choice in this size is more focused, with a BFGoodrich blackwall g-Force Comp 2 AS option available. This size should be considered only after confirming that the car is one of the 17-inch configurations or has been intentionally kept on that wheel diameter.
Sub-model fitment matters on the 2005 Lincoln LS because tire size changes with trim. Appearance, Luxury, and Premium models use one wheel-and-tire package, while Sport and Ultimate models use a different size, so identifying the exact version comes before choosing a tire.

2005 Lincoln LS Appearance
The 2005 Lincoln LS Appearance uses the 225/55R16 radial fitment. Tire selection for this trim comes down to staying with the correct 16-inch size and comparing the available blackwall performance-oriented options within that specification.
The 2005 Lincoln LS Luxury uses the 225/55R16 radial size. That keeps the focus on confirming the 16-inch wheel setup and then choosing among the available radial tires that suit the car's intended road use and overall character.
The 2005 Lincoln LS Premium also uses 225/55R16 radial tires. For this trim, the key step is verifying that the car still wears the proper 16-inch wheels before comparing tire series and other product differences within the correct size.
The 2005 Lincoln LS Sport uses the larger 235/50R17 radial fitment. That makes wheel-diameter confirmation especially important, since the tire choice should match the 17-inch setup rather than the 16-inch size used on other LS trims.
The 2005 Lincoln LS Ultimate uses 235/50R17 radial tires. Choosing for this trim starts with confirming the 17-inch wheel package and then evaluating the available radial option in the proper size for the car's existing setup.
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.

Tire Size & Fitment
What tire size fits a 2005 Lincoln LS?
The 2005 Lincoln LS uses two tire sizes: 225/55R16 and 235/50R17. Appearance, Luxury, and Premium models use 225/55R16, while Sport and Ultimate models use 235/50R17. Both are radial fitments, but they are tied to different wheel diameters and trim levels.
The practical step is to confirm the exact sub-model and check the wheels currently on the car before ordering tires. Many LS sedans have changed hands over the years, and a wheel swap can put a different diameter on the vehicle than the trim originally used. Matching the tire to the wheel diameter on the car is essential.
What size rim does a 2005 Lincoln LS use?
A 2005 Lincoln LS uses either a 16-inch or 17-inch rim, depending on the trim. The 225/55R16 fitment uses a 16-inch rim, and the 235/50R17 fitment uses a 17-inch rim. The wheel diameter is built into the tire size itself, so the final number in the size code is a key fitment detail.
Checking the actual wheel on the car matters just as much as knowing the trim. A replacement tire must match the rim diameter exactly, so a 16-inch tire cannot be mounted on a 17-inch wheel, and vice versa. Looking at the current tire sidewall and measuring the wheel setup helps prevent ordering the wrong size.
Do all 2005 Lincoln LS sub-models use the same tire size?
No, the 2005 Lincoln LS does not use one tire size across every sub-model. Appearance, Luxury, and Premium trims use 225/55R16, while Sport and Ultimate trims use 235/50R17. That means the LS range splits into two distinct wheel-and-tire packages rather than one shared fitment.
This difference affects more than just the tire label on the sidewall. It changes the wheel diameter the tire must fit, and it narrows the correct product choices for each trim. Buyers should identify the exact sub-model first, then confirm that the car still has the proper wheel size before selecting a replacement tire.
Choosing the Right Tire
What should I consider when choosing a tire for a 2005 Lincoln LS?
Start with the correct size for the trim: 225/55R16 for Appearance, Luxury, and Premium, or 235/50R17 for Sport and Ultimate. From there, compare construction, rim-width compatibility, tire series, and the kind of road use the car sees. On this LS, all of the available choices are modern radial blackwall tires.
A buyer using the car mainly for everyday driving may weigh the available all-season style option differently than someone focused on a more performance-oriented feel. It also helps to confirm that the wheel width falls within the tire's supported range, especially if the car no longer wears its original wheels.
What brands offer tires for the 2005 Lincoln LS?
BFGoodrich is the brand available for the 2005 Lincoln LS in the supported sizes here. The 225/55R16 fitment is offered in BFGoodrich g-Force Sport Comp 2 and g-Force Comp 2 AS versions, while the 235/50R17 size is available in BFGoodrich g-Force Comp 2 AS form.
That means brand comparison is less important on this page than comparing series and fitment details within the correct size. The more useful decision is whether the car needs the 16-inch or 17-inch tire, then whether the available series and wheel-width specifications match the vehicle's setup and intended use.
What tire series are available for the 2005 Lincoln LS?
Two BFGoodrich tire series appear in the supported 2005 Lincoln LS fitments: g-Force Sport Comp 2 and g-Force Comp 2 AS. The 225/55R16 size has both series available, while the 235/50R17 fitment is offered in the g-Force Comp 2 AS series. All of them use blackwall radial construction.
This gives the 16-inch fitment more room for comparison within the same size, while the 17-inch setup is more straightforward. Once the proper tire size is confirmed, buyers can compare the series on offer along with wheel-width compatibility, weight, and the overall character they want from the car's replacement tires.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Lincoln LS?
A period-style 2005 Lincoln LS should start with the tire size that matches its trim and wheel package: 225/55R16 for Appearance, Luxury, and Premium, or 235/50R17 for Sport and Ultimate. Since the LS is a modern-era sedan with radial factory-era fitment, the emphasis is on keeping the correct modern size and wheel diameter rather than choosing between vintage constructions.
Appearance on this page is fairly straightforward because the available products are blackwall radials. For a more authentic presentation, the key is preserving the correct stance and wheel size rather than chasing a classic-car sidewall treatment. A car that has been modified with aftermarket wheels may need a closer fitment review before returning to a more original look.
Does correct tire fitment matter for a 2005 Lincoln LS restoration?
Yes, correct tire fitment matters on a 2005 Lincoln LS restoration because the car used two different trim-based sizes and two wheel diameters. Restoring the car with the wrong tire size can affect its appearance, wheel compatibility, and overall presentation. The right size helps preserve the look intended for that particular LS configuration.
A careful restoration should verify the exact sub-model and confirm whether the wheels on the car match that trim's original diameter. On a modern collector sedan like the LS, restoration-oriented tire selection is usually less about wide visual variety and more about getting the proportions, stance, and wheel-and-tire relationship back into the proper range.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Lincoln LS?
Yes, modifications can affect tire fitment on a 2005 Lincoln LS. Aftermarket wheels, changes in wheel width, suspension lowering, and other chassis alterations can all change what works safely and cleanly on the car. That matters here because the LS already uses two different factory-type wheel diameters depending on trim.
Even when the tire size matches a factory LS application, the actual car may no longer have its original wheel setup. A modified LS should be checked for wheel diameter, wheel width, tire-to-fender clearance, and steering clearance before replacement tires are chosen. Those checks are especially important when moving between the 16-inch and 17-inch fitment groups.
What should I inspect before driving a 2005 Lincoln LS on new tires?
Before driving a 2005 Lincoln LS on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and check that inflation is set correctly for the installation. It also helps to look over the suspension and alignment-related wear points so the new tires begin service on a sound chassis.
A brief clearance check at full steering lock is worthwhile, especially if the car has non-original wheels or suspension changes. After the first drives, recheck air pressure and watch for any signs of rubbing, vibration, or uneven wear. Those early checks help confirm that the new tires are working properly with the LS's existing setup.
How often should tires on a 2005 Lincoln LS be inspected?
Tires on a 2005 Lincoln LS should be inspected regularly, not just when tread looks low. A quick visual check for cracking, cuts, bulges, uneven wear, and air loss is a good habit, especially on a car that may see mixed use or spend time parked. Pressure should also be checked routinely rather than assumed.
Collector-minded or lower-mileage cars deserve even closer attention because age and storage conditions can matter as much as mileage. Looking over the sidewalls and tread before longer drives is especially important on an LS that sits for extended periods. Regular inspection helps catch condition issues early and protects the fitment investment already made.
