The 2004 Jaguar XJR sits at the sharp end of Jaguar’s early-2000s supercharged luxury-sedan formula, blending understated British styling with serious high-speed capability. Buyers looking at one today are usually balancing performance, road manners, and the right visual presentation for a modern collector sedan. Tire selection starts with two radial fitments, 255/40R19 and 255/35R20, both tied to this exact model and both carrying the same overall diameter on different wheel diameters. That opens the door to choices in blackwall, raised white letter, and redline sidewall treatments, along with several sport-oriented tire series. The key is confirming which wheel diameter is on the car before comparing appearance, construction details, and intended use.
Which Tire Size Is Right for The 2004 Jaguar XJR
The 2004 Jaguar XJR uses two primary tire sizes, and the first step is confirming whether the car is on 19-inch or 20-inch wheels. Both sizes are radial fitments and both appear on the XJR Base, so the real decision is tied to wheel diameter first, then to the tire series, sidewall style, and overall presentation that best suits the car.
A 255/35R20 tire uses a 255-millimeter section width, a 35-series aspect ratio, radial construction, and fits a 20-inch wheel. On a 2004 Jaguar XJR, this is a low-profile modern performance fitment that preserves the car’s larger-wheel setup while keeping the same overall diameter seen in the 19-inch alternative. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, raised white letter, and redline sidewall treatments depending on the tire series. This size is the right place to start when the car already wears 20-inch wheels and the goal is to compare performance-oriented options without changing wheel diameter.
A 255/40R19 tire has the same 255-millimeter nominal width, uses radial construction, and fits a 19-inch wheel with a slightly taller sidewall than the 20-inch version. For the 2004 Jaguar XJR, it serves the same overall tire diameter on a different rim diameter, making wheel confirmation more important than comparing the two sizes by appearance alone. Product choices include BFGoodrich and Pro-Trac offerings across blackwall, raised white letter, and redline styles, with several sport-oriented series represented. This size deserves close attention when the car remains on 19-inch wheels and the buyer wants to preserve that setup while choosing among different tread and sidewall presentations.
Sub-model fitment is straightforward here because the covered 2004 Jaguar XJR Base uses both primary tire sizes. The important check is not trim level so much as the actual wheel diameter currently on the car, since 19-inch and 20-inch wheels require different tire sizes.

2004 Jaguar XJR Base
The 2004 Jaguar XJR Base uses both 255/40R19 and 255/35R20 radial tire sizes, depending on the wheel setup on the car. That makes wheel confirmation the first step, followed by choosing the preferred tire series and sidewall treatment within the correct size.
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.

These 2004 Jaguar XJR tire FAQs focus on the two correct sizes, the difference between the 19-inch and 20-inch fitments, product-selection details such as sidewall style and series, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2004 Jaguar XJR?
The 2004 Jaguar XJR uses two radial tire sizes: 255/40R19 and 255/35R20. Both apply to the XJR Base, and both share the same overall tire diameter while fitting different wheel diameters.
That means the correct choice depends on the wheels currently installed on the car. A 19-inch wheel requires 255/40R19, while a 20-inch wheel requires 255/35R20. Before choosing a tire, confirm the actual wheel diameter on the vehicle rather than assuming one size from the model name alone.
What size rim does a 2004 Jaguar XJR use?
A 2004 Jaguar XJR uses either a 19-inch or 20-inch rim, depending on which of its two tire sizes is on the car. The 255/40R19 tire fits a 19-inch rim, and the 255/35R20 tire fits a 20-inch rim.
That difference is critical because the two tire sizes are not interchangeable across the same wheel. Once rim diameter is confirmed, compare the tire’s stated rim-width range where available and make sure the wheel setup has not been changed from stock-style dimensions by aftermarket wheels or previous modifications.
Why does the 2004 Jaguar XJR have more than one tire size?
The 2004 Jaguar XJR has more than one tire size because it appears with two wheel diameters: 19 inches and 20 inches. The sizes are 255/40R19 and 255/35R20, and both keep the same overall diameter while matching different rims.
This is why wheel diameter matters more than trim identification on this page. A buyer should verify the wheel itself, then choose tires within the matching size. That avoids ordering a 19-inch tire for a 20-inch wheel or vice versa, even though the section width and overall height are closely aligned.
Choosing the Right Tire
What should I consider when choosing a 255/40R19 or 255/35R20 tire for a 2004 Jaguar XJR?
Start with the correct size for the wheel diameter already on the car, since the 2004 Jaguar XJR uses either 255/40R19 or 255/35R20. From there, compare radial tire series, sidewall style, and any stated rim-width or load-capacity details that matter to your intended use.
A buyer looking for a restrained modern look may prefer blackwall, while someone after a more custom presentation may focus on raised white letter or redline options. It also helps to compare the car’s current wheel width against the tire’s approved range where that specification is given.
What sidewall styles are available for 2004 Jaguar XJR tires?
The available sidewall styles for 2004 Jaguar XJR tires include blackwall, RWL, and redline. Those choices appear across both primary sizes, so sidewall appearance can be part of the selection process whether the car is using 19-inch or 20-inch wheels.
Blackwall keeps the presentation closest to a contemporary sport-luxury look, while RWL and redline create a more distinctive visual statement. Appearance should still come after size and wheel confirmation, since the first requirement is matching the tire to the correct rim diameter and wheel setup already on the car.
What brands offer tires for the 2004 Jaguar XJR?
Tires for the 2004 Jaguar XJR are available from BFGoodrich, Nitto, and Pro-Trac in the covered sizes. Depending on the size, the selection includes series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III.
The practical difference is not just brand name but also the combination of tire series, sidewall treatment, and wheel-diameter fitment. Comparing those details helps narrow the choice between a more understated blackwall performance tire and a more visually assertive option such as raised white letter or redline.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Jaguar XJR?
A period-style 2004 Jaguar XJR tire choice usually starts with keeping the car on its correct wheel diameter and selecting a modern radial in 255/40R19 or 255/35R20 that suits the sedan’s original era and character. Blackwall options typically maintain the most restrained early-2000s luxury-performance presentation.
Some owners may prefer a more individualized look, especially on a modified or show-oriented car, and that is where redline or raised white letter options become relevant. If exact originality matters, compare the car’s current appearance with period photos, marque references, and vehicle-specific documentation before making a final decision.
How does tire construction affect the appearance of a restored 2004 Jaguar XJR?
Construction is simple on the 2004 Jaguar XJR because both primary fitments are modern radial tires. That means appearance differences come less from bias-ply versus radial considerations and more from sidewall treatment, tread character, and whether the car is on 19-inch or 20-inch wheels.
A blackwall radial generally gives the car the cleanest factory-era impression, while RWL or redline options shift the look toward a more custom presentation. Wheel diameter also influences the visual balance, so preserving the intended stance and profile means matching the tire size to the wheel actually fitted to the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Jaguar XJR?
Yes, modifications can affect tire fitment on a 2004 Jaguar XJR, especially when wheel diameter, wheel width, offset, ride height, or suspension components have been changed. The car’s two approved tire sizes already depend on wheel diameter, so any departure from the original-style setup deserves extra attention.
Aftermarket wheels can change the clearance picture even when the tire size looks correct on paper. Check the wheel dimensions, inspect inner and outer clearance at full steering lock, and make sure the suspension and alignment are in sound condition before settling on a replacement tire in either XJR size.
What should I inspect before driving a 2004 Jaguar XJR on new tires?
Before driving a 2004 Jaguar XJR on new tires, confirm that the tire size matches the wheel diameter, check inflation pressure, and inspect for any interference around the fenders, suspension, and steering range. Lug torque, wheel condition, and valve-stem condition also deserve attention before regular road use.
A short initial test drive is a smart follow-up, especially on a car with low-profile 19-inch or 20-inch fitments. Listen for rubbing, feel for vibration, and recheck pressure after the first miles. On a collector or lightly used XJR, it also helps to inspect the rest of the car for age-related suspension wear.
What should I check before a longer drive in a 2004 Jaguar XJR?
Before a longer drive in a 2004 Jaguar XJR, inspect tread and sidewalls for cracking, cuts, bulges, or uneven wear, and confirm that the car is on the correct 255/40R19 or 255/35R20 size for its wheels. Proper inflation and a close look at overall tire condition matter as much as tread depth.
Longer trips place more demand on a high-performance luxury sedan, so it is wise to check alignment behavior, balance, and any signs of air loss before heading out. Collector vehicles that spend time parked should also be reviewed for age, flat spotting, and storage-related deterioration before sustained highway use.
