The 2008 Jaguar XKR sits in the modern grand-touring tradition, blending supercharged performance with the long-hood, elegant coupe and convertible character that made Jaguar performance cars distinctive. At this level, tire choice is not a minor detail, because the XKR uses a staggered radial setup with different front and rear sizes and either 19-inch or 20-inch wheel fitment depending on the vehicle's wheel package. That makes the real decision less about vintage-style construction and more about confirming wheel diameter, front-versus-rear sizing, and the look you want from blackwall, raised white letter, or redline options. For a well-sorted XKR, correct sizing and wheel compatibility come first.
Which Tire Size Is Right for The 2008 Jaguar XKR
The 2008 Jaguar XKR uses four primary tire sizes, and the right one depends first on wheel diameter and position on the car. Front and rear fitment are staggered, with one pair of sizes used on 19-inch wheels and another pair used on 20-inch wheels, so identifying the exact wheel setup is the first step before comparing tire series, sidewall style, or brand.
245/40R19 is a metric radial size in which 245 identifies nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2008 Jaguar XKR, this size is used at the front with the 19-inch staggered setup, making steering feel, wheel compatibility, and front-end clearance especially important. Available choices center on BFGoodrich blackwall performance radials across the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This is the size to evaluate when the car carries 19-inch front wheels and you want to compare front-tire character within the correct fitment envelope.
255/35R20 is a metric radial size with a 255-millimeter nominal section width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2008 Jaguar XKR, it serves as the front tire size for the 20-inch staggered arrangement, so it must be matched to the correct front wheel package rather than treated as a universal XKR fitment. Product choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, raised white letter, and redline sidewall treatments depending on the tire series. This size becomes the focus when the car is equipped with 20-inch front wheels and appearance is part of the selection process.
275/35R19 is a metric radial size where 275 gives the nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 19 is the wheel diameter in inches. On the 2008 Jaguar XKR, this is the rear tire size paired with the 19-inch front fitment, so it is part of a staggered setup rather than a stand-alone choice. BFGoodrich and Nitto offer blackwall tires in this size, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 selections. This is the rear size to confirm when the car runs 19-inch wheels and you want to maintain the proper front-to-rear relationship.
285/30R20 is a metric radial size with a 285-millimeter nominal section width, a 30-series profile, radial construction, and a 20-inch rim diameter. On the 2008 Jaguar XKR, it is the rear companion size for the 20-inch staggered wheel setup, so it should be chosen only after confirming the car's rear wheel diameter and overall package. Available products include Nitto blackwall and Pro-Trac Street Pro III tires in raised white letter and redline forms, giving this size a broader appearance range than a typical modern performance fitment. It is the correct rear size to evaluate when the XKR is equipped with 20-inch wheels.
Fitment is consistent across the Base and Portfolio versions in the sense that both use the same front-and-rear staggered size pairings. What matters most is confirming whether the car has the 19-inch or 20-inch wheel setup, then matching the proper front and rear sizes to that package.

2008 Jaguar XKR Base Front
The 2008 Jaguar XKR Base Front uses the same front-fitment pattern as the Portfolio, with one size tied to the 19-inch setup and another tied to the 20-inch setup. Tire selection here starts with wheel diameter, then moves to brand, tire series, and whether a blackwall, raised white letter, or redline presentation suits the car.
The 2008 Jaguar XKR Base Rear follows the matching staggered rear fitment for either the 19-inch or 20-inch wheel package. Choosing the rear tire means keeping the correct front-to-rear relationship intact and confirming that the selected tire matches the actual rear wheel diameter on the car.
The 2008 Jaguar XKR Portfolio Front uses the same front tire-size pattern as the Base version, with separate fitments for 19-inch and 20-inch wheels. The practical decision is to verify which front wheel package the car carries, then compare radial tire options by series, sidewall treatment, and rim compatibility.
The 2008 Jaguar XKR Portfolio Rear shares the same staggered rear-size approach as the Base model, with one rear size for 19-inch wheels and another for 20-inch wheels. That keeps the selection process centered on wheel confirmation first, then on choosing the tire style and brand that match the intended look and road use.
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 2008 Jaguar XKR Tires for Sale
Available 2008 Jaguar XKR tires center on radial performance offerings from BFGoodrich, Nitto, and Pro-Trac. Depending on size, buyers can compare blackwall, raised white letter, and redline sidewalls across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, and Street Pro III.
For the 2008 Jaguar XKR, the key questions usually involve staggered front-and-rear sizing, 19-inch versus 20-inch wheel fitment, available radial tire styles, and what to inspect before putting a high-performance grand touring Jaguar back on the road.
Tire Size & Fitment
What tire size fits a 2008 Jaguar XKR?
The 2008 Jaguar XKR uses a staggered tire setup rather than one universal size. The 19-inch arrangement uses 245/40R19 in front and 275/35R19 in the rear, while the 20-inch arrangement uses 255/35R20 in front and 285/30R20 in the rear.
That means the first check is the wheel package on the car, followed by front-versus-rear position. An XKR with 19-inch wheels should stay with the matching 19-inch front and rear pair, and the same applies to the 20-inch setup. Mixing sizes outside the intended wheel arrangement can create fitment, clearance, and handling issues.
What size rim does a 2008 Jaguar XKR use?
A 2008 Jaguar XKR uses either 19-inch or 20-inch rims, depending on which tire package is on the car. The 245/40R19 and 275/35R19 sizes fit 19-inch wheels, while the 255/35R20 and 285/30R20 sizes fit 20-inch wheels.
Wheel diameter should be confirmed before selecting tires, especially on a car that may have changed hands or received aftermarket wheels. The XKR also uses different front and rear sizes, so confirming only one wheel is not enough. Checking the actual wheel markings and current tire sizes helps prevent ordering the right section width for the wrong rim diameter.
Do all 2008 Jaguar XKR sub-models use the same tire size?
The Base and Portfolio versions share the same fitment pattern, but not one single tire size across every position. Both use a staggered setup, with one front size and one rear size for the 19-inch package, and a different front-and-rear pair for the 20-inch package.
That makes the sub-model less important than wheel diameter and tire position. A Base Front and Portfolio Front follow the same size logic, and the same is true at the rear. The practical step is to verify whether the car has 19-inch or 20-inch wheels, then select the proper front and rear sizes for that exact setup.
Choosing the Right Tire
What should I consider when choosing a 2008 Jaguar XKR tire?
Start with the actual wheel package and the tire's position on the car, because the 2008 Jaguar XKR uses different front and rear sizes and two possible rim diameters. Every primary fitment here is radial, so the choice becomes one of correct size, wheel compatibility, tire series, and sidewall presentation.
From there, compare the tire's intended character with how the car is used. Some XKR owners will prefer a straightforward blackwall performance look, while others may want raised white letter or redline styling on the 20-inch sizes. Rim-width compatibility, load figures where stated, and overall vehicle setup should be reviewed before making the final selection.
What sidewall styles are available for 2008 Jaguar XKR tires?
Sidewall choice depends on size, but the 2008 Jaguar XKR has more than one appearance option. Blackwall tires are available across all four primary sizes, while the 20-inch front and rear sizes also offer raised white letter and redline choices through the Pro-Trac Street Pro III line.
That gives the XKR owner a real styling decision in addition to basic fitment. A blackwall tire keeps the look more understated and contemporary, while raised white letter or redline sidewalls create a more customized presentation. The key is to keep the sidewall choice secondary to proper front-and-rear sizing and the correct 19-inch or 20-inch wheel package.
What brands offer tires for the 2008 Jaguar XKR?
The 2008 Jaguar XKR is served by BFGoodrich, Nitto, and Pro-Trac, depending on the tire size. BFGoodrich appears across the 19-inch and 20-inch front fitments and the 19-inch rear size, while Nitto and Pro-Trac broaden the options in the 20-inch applications and Nitto also appears in 275/35R19.
Brand selection should be treated as part of the overall fitment decision rather than a stand-alone shortcut. Some sizes have more series choices than others, and some appearance options are tied to specific brands. It helps to compare each tire by its exact size, sidewall style, and wheel compatibility so the front and rear pair remain properly matched.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Jaguar XKR?
A period-style 2008 Jaguar XKR usually starts with the correct staggered radial size set for the car's actual 19-inch or 20-inch wheels. Blackwall tires keep the appearance closer to the restrained grand-touring look many owners expect, while 20-inch raised white letter and redline options move the car toward a more customized presentation.
Because this is a modern performance Jaguar rather than an earlier bias-ply-era classic, the visual question is mostly about sidewall treatment and overall stance, not construction type. Owners pursuing exact originality should compare any planned tire choice with factory literature, window-sticker documentation, or marque-specific reference material before settling on a final appearance.
Does correct tire fitment matter for a 2008 Jaguar XKR restoration?
Correct tire fitment matters on a 2008 Jaguar XKR restoration because the car's stance, wheel-to-fender relationship, and overall visual balance depend on the proper front and rear size pairing. Using the intended 19-inch or 20-inch staggered setup helps the restored car look settled and proportioned rather than mismatched.
Fitment also affects how convincing the finished restoration feels in use. A wrong-profile front tire or an incorrect rear diameter can change the visual character even before the car moves. Checking wheel diameter, front-versus-rear sizing, and the sidewall style you want is just as important as choosing paint, trim, and wheel finish on a modern collectible Jaguar.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Jaguar XKR?
Yes, modifications can affect tire fitment on a 2008 Jaguar XKR, especially because the car already uses a staggered setup and either 19-inch or 20-inch wheels. Aftermarket wheels, altered offsets, suspension changes, or lowering can all change how a 245/40R19, 255/35R20, 275/35R19, or 285/30R20 tire sits in the wheel opening.
The safest approach is to verify the actual wheel diameter and width on the car before choosing tires, then inspect clearance at steering lock and under suspension movement. Even when the size itself is correct for an XKR, a modified wheel or ride-height change can affect inner clearance, outer fender space, and the front-to-rear balance of the setup.
What should I inspect before driving a 2008 Jaguar XKR on new tires?
Before driving a 2008 Jaguar XKR on new tires, inspect wheel condition, confirm that the correct front and rear sizes were installed, and check inflation pressure. It also makes sense to look over valve stems, tread seating, and any obvious signs of rubbing or uneven clearance once the car is back on the ground.
A short, careful road test should follow, with attention to steering feel, vibration, and any contact noise over bumps or during turns. Because the XKR is a high-performance grand tourer with staggered sizing, rechecking pressure and visually inspecting the tire shoulders after the first drive can catch mounting or clearance issues before they become expensive problems.
What should I check before a longer drive in a 2008 Jaguar XKR?
Before a longer drive, confirm that the 2008 Jaguar XKR is on the correct staggered tire pair for its wheel package and that all four tires are in sound condition. Pressure, tread depth, sidewall condition, and any signs of cuts, bulges, cracking, or slow air loss deserve attention before the trip begins.
A longer outing also makes it worth checking overall chassis readiness, since a tire can only perform as well as the wheel and suspension setup around it. The XKR should roll without vibration, track consistently, and show no evidence of clearance trouble. Cars that sit for long periods benefit from an extra inspection for age-related tire issues before sustained highway use.
