The 2003 Lincoln LS came from a moment when Lincoln aimed to give a midsize luxury sedan a more driver-focused personality, blending premium comfort with sharper road manners than many buyers expected from the brand. That balance matters when choosing tires, because the 2003 Lincoln LS uses two different radial fitments depending on engine and sub-model: 225/55R16 or 235/50R17. Available choices stay firmly in modern radial territory, with BFGoodrich g-Force offerings in blackwall form and more than one g-Force series for some applications. The key is confirming the exact sub-model and wheel diameter first, then choosing a tire that matches the car's intended mix of appearance, handling, and everyday road use.
Which Tire Size Is Right for The 2003 Lincoln LS
The 2003 Lincoln LS uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. V6 configurations use 225/55R16 on a 16-inch rim, while V8 configurations use 235/50R17 on a 17-inch rim. Before comparing tire choices, the first step is confirming whether the car is a V6 or V8 and making sure the wheels on the car still match that original diameter.
225/55R16 is a modern metric radial size in which 225 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 2003 Lincoln LS, this size serves the V6-based fitment and keeps the tire choice within a fully modern radial format. Available options center on BFGoodrich g-Force series tires in blackwall form, including both g-Force Sport Comp 2 and g-Force Comp 2 AS. This size makes sense when the car retains its 16-inch wheel setup and the goal is staying with the proper V6 fitment.
235/50R17 is also a modern metric radial size, with a 235-millimeter section width, a 50-series profile, radial construction, and a 17-inch wheel diameter. For the 2003 Lincoln LS, this is the fitment used on V8-based versions, so it belongs with the larger original wheel diameter rather than the 16-inch setup. Product choice here is more streamlined, with a BFGoodrich g-Force Comp 2 AS blackwall option in the proper size family. This size should be evaluated when the car is a V8 model and still uses the correct 17-inch wheels.
Sub-model fitment on the 2003 Lincoln LS is straightforward once the engine version is confirmed. V6 models share one tire size, while V8 models use a different size and wheel diameter, so checking the exact sub-model prevents crossing 16-inch and 17-inch fitments.

2003 Lincoln LS LSE V6
The 2003 Lincoln LS LSE V6 uses the same 225/55R16 radial fitment found on the standard V6 model. Tire selection then becomes a matter of choosing among the available blackwall radial options while keeping the original 16-inch wheel diameter in place.
The 2003 Lincoln LS LSE V8 uses the 235/50R17 radial fitment shared with the standard V8 model. That means the important checks are staying with the 17-inch wheel setup and selecting the appropriate radial product for the car's intended road use.
The 2003 Lincoln LS V6 uses a 225/55R16 radial tire on a 16-inch rim. Choosing tires for this sub-model is mostly about matching that size correctly and comparing the available BFGoodrich g-Force series options within the same fitment.
The 2003 Lincoln LS V8 uses a 235/50R17 radial tire on a 17-inch rim. Tire selection should stay focused on that larger-diameter setup, especially if the car's wheels have been changed over the years.
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 2003 Lincoln LS?
The 2003 Lincoln LS uses two tire sizes: 225/55R16 and 235/50R17. The 225/55R16 size applies to V6 models, including the LSE V6, while 235/50R17 applies to V8 models, including the LSE V8. Both are radial fitments in modern metric sizing.
The most important step is matching the size to the car's actual sub-model and wheel diameter. A V6-size tire does not belong on a 17-inch V8 wheel, and a V8-size tire does not belong on a 16-inch V6 wheel. If the car has had wheel changes, verify the wheels on the car before selecting tires.
What size rim does a 2003 Lincoln LS use?
A 2003 Lincoln LS uses either a 16-inch or 17-inch rim, depending on the sub-model. V6 versions use a 16-inch wheel with 225/55R16 tires, while V8 versions use a 17-inch wheel with 235/50R17 tires. The tire size and rim diameter are tied together.
Wheel diameter should be confirmed before comparing brands or tire series, especially on cars that may have been modified. The available 225/55R16 products suit 16-inch rims, and the 235/50R17 fitment suits 17-inch rims. Checking actual wheel markings is a smart step whenever the car's history or equipment is uncertain.
Do all 2003 Lincoln LS sub-models use the same tire size?
No. The 2003 Lincoln LS has split fitment by sub-model. The LS V6 and LSE V6 use 225/55R16, while the LS V8 and LSE V8 use 235/50R17. That means the covered sub-models do not all share one universal tire size.
This distinction matters because the two sizes also use different wheel diameters. Buyers should identify whether the car is a V6 or V8 before moving into product selection, since choosing by appearance alone can lead to the wrong fitment. Once the sub-model is confirmed, comparing available radial options becomes much more straightforward.
Choosing the Right Tire
What should I consider when choosing a tire for a 2003 Lincoln LS?
Start with the correct size for the exact sub-model: 225/55R16 for V6 models or 235/50R17 for V8 models. From there, compare radial construction details, rim-width compatibility, tire series, and whether the car's use leans more toward everyday street driving or a more responsive performance-oriented feel.
The available Lincoln LS products stay within BFGoodrich's g-Force family, so the choice is less about changing size and more about selecting the right version within the proper fitment. It also helps to confirm the car still has the original wheel diameter, since an older luxury sport sedan may have seen aftermarket wheel changes over time.
What brands offer tires for the 2003 Lincoln LS?
The available tires for the 2003 Lincoln LS come from BFGoodrich. In the 225/55R16 fitment, options include g-Force Sport Comp 2 and g-Force Comp 2 AS. In the 235/50R17 fitment, the available product is a BFGoodrich g-Force Comp 2 AS radial.
Since the current selection centers on one brand, the decision shifts toward tire series, size correctness, and wheel compatibility rather than choosing among multiple manufacturers. Buyers should still compare the product details carefully, especially when deciding between a more specific performance series and an all-season-oriented series within the proper Lincoln LS fitment.
What tire series are available for the 2003 Lincoln LS?
The 2003 Lincoln LS tire selection includes BFGoodrich g-Force Sport Comp 2 and BFGoodrich g-Force Comp 2 AS, depending on size. The 225/55R16 fitment has both series available, while the 235/50R17 fitment is represented by the g-Force Comp 2 AS in the available product range.
That makes the V6-size fitment a little broader in product choice, while the V8-size fitment remains more focused. Buyers comparing these series should stay anchored to the correct size first, then review the tire's intended character, rim-width specification, and how the Lincoln LS will actually be driven rather than trying to force a different size onto the car.
Restoration & Appearance
Which tire should I choose for a period-style 2003 Lincoln LS?
A period-style 2003 Lincoln LS still starts with the correct modern radial size for the specific sub-model: 225/55R16 for V6 models or 235/50R17 for V8 models. Because this is a modern luxury sport sedan rather than an earlier classic with bias-ply concerns, the appearance decision is more subtle and centers on staying with the proper overall fitment.
Blackwall presentation suits the available product range and keeps the look clean and contemporary to the car's era. The stronger restoration choice is usually preserving the right wheel diameter and tire proportions rather than chasing an exaggerated visual effect. On cars with non-original wheels, returning to the proper size relationship can matter as much as the tire brand itself.
Does correct tire fitment matter for a 2003 Lincoln LS restoration?
Yes, correct tire fitment matters because the 2003 Lincoln LS used different size and wheel combinations between V6 and V8 versions. Restoring the proper 225/55R16 or 235/50R17 fitment helps maintain the car's intended stance and keeps the wheel-and-tire relationship in line with the original sub-model setup.
That does not mean every available tire is identical in appearance, but it does mean size and wheel diameter should come first. A restoration-minded owner should confirm the exact sub-model, verify the wheel size now on the car, and then select a radial tire that supports the desired presentation without introducing an incorrect fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2003 Lincoln LS?
Yes. Modifications can affect tire fitment on a 2003 Lincoln LS, especially if the car has aftermarket wheels, suspension changes, or altered ride height. Since this model already uses two different factory wheel diameters by sub-model, any change to wheel size or offset can complicate an otherwise straightforward 225/55R16 or 235/50R17 selection.
A modified car should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and suspension movement before new tires are chosen. Even when the tire size looks familiar, the setup may no longer match the original V6 or V8 configuration. That makes physical verification more important than relying only on model-year fitment.
What should I inspect before driving a 2003 Lincoln LS on new tires?
Before driving a 2003 Lincoln LS on new tires, inspect the wheels for damage, confirm the wheel diameter matches the intended tire size, and make sure the tires are mounted in the correct V6 or V8 fitment. It also helps to look over alignment-related wear items and verify that inflation pressure is set appropriately.
A short road test should be followed by another look for clearance issues, rubbing, vibration, or uneven seating. On a car that has spent time parked, checking suspension bushings, steering components, and overall tire age on any remaining older tires is just as important. Small problems show up quickly once a fresh set of tires goes into service.
How should tires on a collector-era 2003 Lincoln LS be maintained?
Tires on a lightly used 2003 Lincoln LS should be maintained with regular pressure checks, visual inspections, and attention to age-related condition as much as tread depth. Blackwall radial tires can still develop cracking, flat-spotting, air loss, or internal deterioration when the car sits for long periods without routine movement and inspection.
Storage conditions matter on a modern collectible just as much as on an older classic. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and occasional movement can reduce flat spotting. Before a longer drive, inspect sidewalls, tread, and valve stems carefully rather than assuming low mileage means the tires are road-ready.
