The 2005 Jaguar XKR sits in the supercharged grand-touring tradition that gave Jaguar’s modern coupes and convertibles their mix of long-hood elegance and serious highway pace. It is a late-classic performance Jaguar, so tire selection is less about vintage construction and more about matching the car’s staggered fitment and wheel setup correctly. This XKR uses radial tires in four sizes across 18-inch and 20-inch applications, with front and rear sizes differing. Available choices include blackwall performance radials as well as raised white letter and redline treatments in some sizes. The key is confirming whether the car is on its 18-inch or 20-inch wheel package before choosing by series, sidewall style, and intended use.
Which Tire Size Is Right for The 2005 Jaguar XKR
The 2005 Jaguar XKR uses four primary tire sizes, and the right choice depends first on confirming whether the car has the 18-inch or 20-inch wheel setup. Fitment is staggered front to rear, so the front and rear tires are not the same size. Once wheel diameter is confirmed, the real decision becomes selecting the right front and rear combination in the appropriate radial series, sidewall style, and performance-oriented product range.
245/45R18 is a metric radial size where 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 18 is the rim diameter in inches. On the 2005 Jaguar XKR, this size serves the front position on the 18-inch setup, making it part of a staggered front-to-rear fitment rather than a universal four-corner size. Available choices center on blackwall radials from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the right size to evaluate when the car retains its 18-inch front wheels and the goal is matching the proper front fitment with the corresponding rear tire.
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 2005 Jaguar XKR, this size is used at the front with the 20-inch staggered wheel package, so it should be paired with the correct 20-inch rear size rather than mixed with the 18-inch combination. Product choices include blackwall options from BFGoodrich and Nitto, along with Pro-Trac Street Pro III versions in raised white letter and redline form. This size matters when the car is already set up on 20-inch front wheels and the owner wants to preserve the intended staggered layout while comparing appearance and series differences.
255/45R18 is a metric radial tire size that uses a 255-millimeter nominal section width, a 45-series profile, radial construction, and an 18-inch rim diameter. For the 2005 Jaguar XKR, it is the rear tire size in the 18-inch staggered arrangement, so its role is different from the 245/45R18 front fitment even though both share the same wheel diameter. Available products include blackwall performance radials from BFGoodrich and Nitto, plus Pro-Trac Street Pro III options in raised white letter and redline styling. It is the size to focus on when the car has the 18-inch rear wheels and the owner wants to compare a traditional blackwall look against more appearance-driven sidewall choices.
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 2005 Jaguar XKR, this size belongs at the rear in the 20-inch staggered setup, giving it a specific role that should be matched to the proper 20-inch front tire. Choices in this size include a blackwall Nitto NT555 G2 and Pro-Trac Street Pro III options with raised white letter or redline sidewalls. This is the size to verify when the car carries 20-inch rear wheels and the buyer is balancing performance-oriented fitment with the visual effect of the sidewall treatment.
Fitment on the 2005 Jaguar XKR is straightforward once wheel diameter and tire position are confirmed, because the front and rear sizes are split rather than shared. Checking the exact front or rear application matters just as much as confirming whether the car is on the 18-inch or 20-inch setup.

2005 Jaguar XKR Base Front
The 2005 Jaguar XKR Base Front uses one of two front tire sizes depending on whether the car has 18-inch or 20-inch wheels, and both are radial fitments. That makes wheel-diameter confirmation the first step, followed by selecting the front tire series and sidewall style that matches the rear setup and the car’s intended use.
The 2005 Jaguar XKR Base Rear uses a different tire size from the front, with one rear radial size for the 18-inch setup and another for the 20-inch setup. Rear tire selection should follow the actual wheel package on the car so the staggered arrangement stays consistent in diameter class, appearance, and fitment balance.
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 Jaguar XKR?
The 2005 Jaguar XKR uses a staggered radial setup with four primary sizes across two wheel packages. The 18-inch combination uses 245/45R18 in front and 255/45R18 in the rear, while the 20-inch combination uses 255/35R20 in front and 285/30R20 in the rear.
Choosing the right size starts with confirming the actual wheels on the car, because the front and rear tires differ and the 18-inch and 20-inch packages are not interchangeable as complete sets. A car with aftermarket wheels or prior tire changes should be checked carefully so the selected front and rear pair matches the rim diameter and intended staggered layout.
What size rim does a 2005 Jaguar XKR use?
A 2005 Jaguar XKR uses either 18-inch or 20-inch rims, depending on the wheel package on the car. The 18-inch setup pairs 245/45R18 front and 255/45R18 rear tires, while the 20-inch setup pairs 255/35R20 front and 285/30R20 rear tires.
Rim diameter is the first detail to verify before choosing tires, because the XKR does not use one wheel size across all fitments. It also helps to confirm front and rear wheel widths before selecting a product, especially if the car has been modified, since staggered performance fitments leave less room for guesswork than a same-size four-corner setup.
Why does the 2005 Jaguar XKR have more than one tire size?
The 2005 Jaguar XKR has more than one tire size because it uses staggered front and rear fitment, and it was offered with both 18-inch and 20-inch wheel packages. That creates two matched front-and-rear combinations rather than one universal tire size for every corner of the car.
This matters because the correct tire choice depends on both position and wheel diameter. Front and rear sizes should be selected as a coordinated pair within the same wheel package, and any owner working with replacement wheels, suspension changes, or previous nonstandard tires should confirm actual wheel measurements and available clearance before ordering a new set.
Choosing the Right Tire
What should I consider when choosing a 2005 Jaguar XKR tire?
Start with the correct front and rear size for the wheel package on the car. The 2005 Jaguar XKR uses radial tires in a staggered arrangement, so the important basics are rim diameter, tire position, construction, and whether the car is staying with the 18-inch or 20-inch setup.
After the fitment is confirmed, compare the available tire series, sidewall style, rim-width specifications, weight, and load figures where they are given. A blackwall performance radial may suit an understated look, while raised white letter or redline versions can change the car’s presentation noticeably without changing the underlying size category.
What sidewall styles are available for 2005 Jaguar XKR tires?
Sidewall choices for the 2005 Jaguar XKR include blackwall, raised white letter, and redline, depending on the tire size. Blackwall options are widely available across the four fitments, while raised white letter and redline treatments appear in certain Pro-Trac Street Pro III sizes.
That makes sidewall style an appearance decision after the correct size and wheel diameter are established. Buyers who want a more contemporary performance look often stay with blackwall, while raised white letter or redline can give the XKR a more customized presentation. The main thing is selecting the sidewall style within the proper front and rear sizes for the car.
What brands offer tires for the 2005 Jaguar XKR?
Tires for the 2005 Jaguar XKR are available from BFGoodrich, Nitto, and Pro-Trac across the covered 18-inch and 20-inch fitments. Depending on size, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice is only one part of the decision. The more useful comparison is how each option lines up with the car’s wheel package, sidewall preference, and intended use, since some sizes have broader series coverage than others. Checking rim-width suitability and keeping the front and rear pair within the same fitment family will narrow the selection quickly.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Jaguar XKR?
A period-style 2005 Jaguar XKR tire choice starts with preserving the correct staggered size combination for the car’s 18-inch or 20-inch wheel package. From there, the decision usually comes down to whether a blackwall performance radial better suits the car’s original grand-touring character or whether a more expressive sidewall treatment fits the owner’s visual goals.
Because the XKR is a modern performance Jaguar rather than an earlier bias-ply-era car, construction is not the restoration issue here; presentation is. Buyers concerned with strict originality should compare wheel and tire appearance against marque references and vehicle history, while those building a clean driver can stay size-correct and choose the sidewall style that complements the car best.
How does tire construction affect the appearance of a restored 2005 Jaguar XKR?
On a restored 2005 Jaguar XKR, tire construction affects appearance less dramatically than it would on an older collector car because the primary fitments are already radial. The more visible difference usually comes from sidewall treatment and tread character within the correct radial size rather than from choosing between bias-ply and radial construction.
That means the visual decision is often blackwall versus a more assertive raised white letter or redline presentation in the sizes where those styles are offered. Keeping the correct staggered dimensions remains the foundation, since an off-size tire can change the car’s stance and look even before any performance or clearance questions come into play.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Jaguar XKR?
Yes, modifications can affect tire fitment on a 2005 Jaguar XKR, especially because the car uses staggered front and rear sizes and may carry either 18-inch or 20-inch wheels. Aftermarket wheels, altered offsets, suspension changes, or nonstandard ride height can all change the room available for the tire.
The safest approach is to confirm the actual wheel diameter and width on the car, then check clearance at the fender, suspension, and steering range before changing sizes or series. A setup that looks close on paper can still create rubbing issues once the car is loaded, turned, or driven over uneven pavement.
What should I inspect before driving a 2005 Jaguar XKR on new tires?
Before driving a 2005 Jaguar XKR on new tires, inspect the wheels for correct diameter and condition, verify that the front and rear sizes match the intended staggered setup, and check inflation carefully. It also makes sense to confirm that each tire seats properly and that there are no signs of immediate air loss.
A short visual check around the car can prevent early problems. Look for fender or suspension clearance concerns, make sure old alignment or wear issues have been addressed, and recheck pressure after the first miles of driving. On a performance grand tourer like the XKR, small setup errors tend to show up quickly in handling feel and tire wear.
How often should tires on a 2005 Jaguar XKR be inspected?
Tires on a 2005 Jaguar XKR should be inspected regularly, not just by mileage. A performance car that is driven occasionally can still develop age-related issues such as cracking, flat spotting, or slow air loss, so visual checks and pressure checks should be part of routine ownership even when tread depth still looks acceptable.
It helps to inspect the tires before longer drives and after storage periods, especially on a low-use collector or fair-weather car. Pay attention to tread wear pattern, sidewall condition, and any vibration that develops on the road. Catching a pressure loss or aging issue early is especially important when the car uses wide rear tires and a staggered fitment.
