The 2004 Jaguar S-Type blends traditional Jaguar sedan character with a more modern sport-luxury layout, giving buyers a car that can range from relaxed touring to distinctly performance-focused trim levels. That matters at the tire level, because this exact S-Type does not use one universal fitment across the lineup. Depending on configuration, the primary sizes are 225/55R16, 235/50R17, or a staggered 245/40R18 front and 275/35R18 rear setup, all in radial construction. Available choices also vary by tire series, brand, and sidewall treatment, especially in the 18-inch sizes. The right selection starts with confirming the exact sub-model and wheel diameter before narrowing the tire style that suits the car's appearance and road use.
Which Tire Size Is Right for The 2004 Jaguar S-Type
The 2004 Jaguar S-Type uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel setup. Rim diameter is the first thing to confirm, since this car appears with 16-inch, 17-inch, and 18-inch wheels, and the 18-inch S-Type R arrangement also uses different front and rear sizes. Once the sub-model and wheel diameter are verified, the next step is choosing among the available radial tire series, brands, and sidewall styles within the proper size.
225/55R16 is a metric radial size in which 225 identifies the section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 16 is the wheel diameter in inches. On the 2004 Jaguar S-Type, this size belongs to the 16-inch fitment and suits buyers staying with the standard wheel diameter. Available choices in this size center on BFGoodrich blackwall radials, including g-Force Sport Comp 2 and g-Force Comp 2 AS series. It is the size to evaluate when the car carries the 16-inch wheel package and the goal is straightforward road-use replacement without moving to a different wheel diameter.
245/40R18 is a metric radial size with a 245-millimeter nominal section width, a 40-series profile, and an 18-inch rim diameter. On the 2004 Jaguar S-Type, this size serves the front position of the S-Type R staggered setup, so it should be treated as a front-specific fitment rather than a universal size for the whole car. Product choice is broader here, with blackwall options from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac versions in redline and raised white letter form. This size deserves close attention when maintaining the S-Type R's intended front-to-rear tire relationship and appearance.
275/35R18 is a metric radial size where 275 gives the nominal section width in millimeters, 35 is the aspect ratio, and 18 is the wheel diameter. On the 2004 Jaguar S-Type, it is the rear tire size used with the S-Type R's staggered 18-inch arrangement, pairing with a narrower front tire rather than being used at all four corners. Choices in this size include blackwall radial series from BFGoodrich and Nitto, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the size to confirm when the car carries the S-Type R rear wheel setup and rear tire width matters as much as rim diameter.
235/50R17 is a metric radial size with a 235-millimeter section width, a 50-series profile, and a 17-inch rim diameter. On the 2004 Jaguar S-Type, this size belongs to the Sport Package configuration, placing it between the 16-inch standard fitment and the staggered 18-inch R setup. The available product selection here is focused, with a BFGoodrich g-Force Comp 2 AS blackwall radial in the correct size. It is the size to verify when the car has the 17-inch sport-oriented wheel package and the goal is to stay with the original wheel diameter and tire profile family.
Tire fitment on the 2004 Jaguar S-Type varies by sub-model, so identifying the exact version of the car is essential before choosing a tire. The main split is between the Base model, the Sport Package car, and the S-Type R's staggered front and rear 18-inch setup.

2004 Jaguar S-Type Base
The 2004 Jaguar S-Type Base uses the 225/55R16 radial fitment on a 16-inch wheel. Tire selection here is mainly about choosing the right blackwall radial series for normal road use while staying with the correct wheel diameter and size.
The 2004 Jaguar S-Type R Front uses 245/40R18, making it one half of the car's staggered radial setup. Tire choice should preserve the front-specific sizing relationship and account for the broader mix of available blackwall, redline, and raised white letter options in this size.
The 2004 Jaguar S-Type R Rear uses 275/35R18, paired with a different front size rather than a same-size four-corner arrangement. That makes rear tire selection especially dependent on confirming the wheel position and maintaining the intended staggered fitment.
The 2004 Jaguar S-Type w/Sport Pkg. uses 235/50R17 on a 17-inch wheel. Choosing tires for this version is straightforward once the package is confirmed, with the focus shifting to staying within the correct size and radial format.
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.
Best 2004 Jaguar S-Type Tires for Sale
Available 2004 Jaguar S-Type tires are all radial, with choices that vary by sub-model and wheel diameter. The 18-inch sizes offer the widest comparison across BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, including blackwall, redline, and raised white letter sidewall treatments.
Common 2004 Jaguar S-Type tire questions usually come down to exact sub-model fitment, wheel diameter, staggered S-Type R sizing, and how to compare the available radial tire series, sidewall styles, and road-use considerations.
Tire Size & Fitment
What tire size fits a 2004 Jaguar S-Type?
The 2004 Jaguar S-Type uses more than one tire size depending on the version of the car. The Base model uses 225/55R16, the S-Type with Sport Package uses 235/50R17, and the S-Type R uses a staggered 18-inch setup with 245/40R18 in front and 275/35R18 in the rear.
The practical starting point is to confirm the exact sub-model and wheel diameter already on the car. A Base sedan, Sport Package car, and S-Type R do not share one universal tire size, and the R also requires attention to front-versus-rear placement before comparing tire options.
What size rim does a 2004 Jaguar S-Type use?
The 2004 Jaguar S-Type appears with 16-inch, 17-inch, and 18-inch wheel diameters depending on configuration. The 225/55R16 size uses a 16-inch rim, 235/50R17 uses a 17-inch rim, and the S-Type R's 245/40R18 and 275/35R18 sizes both use 18-inch rims.
Wheel diameter should be checked before anything else because it narrows the fitment immediately. Once the rim diameter is confirmed, the next step is making sure the tire size matches the exact sub-model, and in the case of the S-Type R, the correct axle position as well.
Why does the 2004 Jaguar S-Type have more than one tire size?
The 2004 Jaguar S-Type has more than one tire size because different sub-models use different wheel and tire packages. The Base model, Sport Package version, and S-Type R do not share the same fitment, and the S-Type R also uses separate front and rear sizes instead of a same-size arrangement.
That means tire selection cannot be based on year and model alone. Checking the exact trim, the wheel diameter, and whether the car has a staggered setup keeps the search focused on the correct size before comparing brands, tire series, or sidewall treatments.
Choosing the Right Tire
What should I consider when choosing a 2004 Jaguar S-Type tire?
Start with the basics: the correct sub-model, the correct wheel diameter, and the exact tire size assigned to that configuration. On a 2004 Jaguar S-Type, that means distinguishing between 225/55R16, 235/50R17, and the S-Type R's staggered 245/40R18 front and 275/35R18 rear fitment.
After size is settled, compare the available radial tire series, sidewall style, and rim-width specifications for the tire under consideration. A buyer focused on everyday street use may choose differently from someone trying to preserve a sportier or more customized appearance, especially in the 18-inch sizes.
What sidewall styles are available for 2004 Jaguar S-Type tires?
Blackwall is the most common sidewall style across the available 2004 Jaguar S-Type tire sizes. In the 245/40R18 fitment used on the S-Type R front position, there are also Pro-Trac Street Pro III options with redline and raised white letter sidewalls.
Sidewall style mainly affects appearance, so the right choice depends on how original-looking, understated, or custom the car is meant to feel. It still needs to be selected within the correct size and wheel application, especially on an S-Type R where front and rear tires are not interchangeable.
What brands offer tires for the 2004 Jaguar S-Type?
Available 2004 Jaguar S-Type tire brands include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, although the selection depends on the exact size. BFGoodrich appears across all four fitments, while Nitto, M&H Racemaster, and Pro-Trac are concentrated in the 18-inch S-Type R front and rear sizes.
Brand comparison makes the most sense after confirming the car's correct tire size. Once that is settled, the useful differences are usually tire series, sidewall treatment, and rim-width compatibility rather than simply choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Jaguar S-Type?
A period-style 2004 Jaguar S-Type starts with keeping the correct wheel diameter and tire size for the exact sub-model. That means 225/55R16 for the Base model, 235/50R17 for the Sport Package version, or the S-Type R's 245/40R18 front and 275/35R18 rear combination.
Appearance choices can then be narrowed by tire series and sidewall style within the proper fitment. Blackwall gives the most restrained look across the lineup, while the 245/40R18 size also offers redline and raised white letter options for a more customized presentation.
How does tire construction affect the appearance of a restored 2004 Jaguar S-Type?
On the 2004 Jaguar S-Type, the available primary fitments are radial tires, so the construction itself already reflects the car's modern era. The visual differences are less about bias-ply versus radial and more about sidewall treatment, tire series, and keeping the correct proportions for the wheel size.
A restored or carefully kept S-Type usually looks most cohesive when the tire size matches the car's intended wheel package and stance. Sidewall details such as blackwall, redline, or raised white letter can change the presentation noticeably without changing the basic radial construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Jaguar S-Type?
Yes. A 2004 Jaguar S-Type with aftermarket wheels, suspension changes, or altered ride height may need more scrutiny even when the tire size appears close to stock. This matters most on the S-Type R, where front and rear tire sizes are already different from each other in the original staggered layout.
Wheel width, offset, steering clearance, and fender room should all be checked on a modified car before changing tires. Even a correct-size tire can create problems if the wheel setup has changed, so the actual hardware on the car matters as much as the factory-size reference.
What should I inspect before driving a 2004 Jaguar S-Type on new tires?
Before road use, inspect the wheels for damage, confirm that each tire is mounted in the correct size and position, and check inflation pressure carefully. On an S-Type R, that also means verifying that the 245/40R18 tires are on the front and the 275/35R18 tires are on the rear.
A quick road-use check should also include alignment condition, visible suspension wear, and basic clearance through steering and suspension movement. These steps help the car make proper use of the new tires and reduce the chance of uneven wear, rubbing, or avoidable handling issues.
How often should tires on a 2004 Jaguar S-Type be inspected?
Tires on a 2004 Jaguar S-Type should be inspected regularly, not just when tread looks worn. A routine check for pressure loss, cuts, punctures, uneven wear, bulges, and sidewall cracking is especially important on a car that may see seasonal, enthusiast, or lower-mileage use.
Collector-minded or infrequently driven cars can age tires out before they wear them out, so condition matters as much as mileage. Regular inspection also helps catch setup issues early, particularly on staggered-fitment S-Type R models where front and rear tires perform different jobs and should wear differently.
