The 2001 Jaguar XK8 sits in the grand-touring tradition that defined Jaguar coupes and convertibles for decades, blending long-hood luxury with modern V8-era refinement. By this point, the XK8 had become a distinctly modern Jaguar, and its tire fitment reflects that with radial sizes on both 17-inch and 18-inch wheels. A Base model uses 245/50R17, while the 18-inch setup pairs 245/45R18 front tires with 255/45R18 rears. That staggered arrangement changes the tire decision from simply picking a size to confirming wheel diameter, axle position, and the sidewall or performance character that best suits the car's appearance and road use.
Which Tire Size Is Right for The 2001 Jaguar XK8
Three primary tire sizes apply to the 2001 Jaguar XK8, and the right one depends first on wheel diameter and whether the car uses the 17-inch single-size setup or the 18-inch front-and-rear staggered arrangement. The Base model uses 245/50R17, while the 18-inch configuration uses 245/45R18 in front and 255/45R18 in the rear. Before choosing a tire, confirm the exact wheel package on the car.
A 245/50R17 tire is a metric radial size with a 245-millimeter nominal section width, a 50-series aspect ratio, radial construction, and fitment for a 17-inch wheel. On the 2001 Jaguar XK8, this is the primary size for the Base model using the 17-inch setup. Its role is straightforward compared with the staggered 18-inch arrangement, since all four tires use the same size. The key reason to choose this size is to preserve the correct fitment for an XK8 that remains on its original 17-inch wheel diameter rather than converting to a different wheel package.
A 245/45R18 tire uses a 245-millimeter nominal section width, a 45-series profile, radial construction, and an 18-inch rim diameter. On the 2001 Jaguar XK8, this size serves the front position in the 18-inch staggered setup, so it should not be treated as a universal four-corner fitment. Available choices include BFGoodrich and Nitto products in blackwall form across several performance-oriented series. This size matters when keeping the intended front tire specification on an XK8 equipped with 18-inch wheels and a wider rear tire.
A 255/45R18 tire is a metric radial with a 255-millimeter nominal section width, a 45-series profile, and an 18-inch wheel fitment. On the 2001 Jaguar XK8, this size is used at the rear in the 18-inch staggered configuration, giving it a distinct role from the narrower 245/45R18 front tire. Product choice is broader here, including BFGoodrich, Nitto, and Pro-Trac options with blackwall, raised white letter, and redline sidewall treatments. This is the size to evaluate when the car has the 18-inch rear wheel setup and appearance preference plays a larger role in selection.
Sub-model fitment on the 2001 Jaguar XK8 is not uniform, because the covered configurations include both a 17-inch single-size setup and an 18-inch staggered front-and-rear arrangement. Checking the exact sub-model matters before tire selection, especially when front and rear sizes differ.

2001 Jaguar XK8 Base
The 2001 Jaguar XK8 Base uses a single radial tire size on 17-inch wheels rather than a staggered arrangement. Tire selection is centered on keeping the correct 17-inch fitment and confirming the car has not been changed to a different wheel package.
The 2001 Jaguar XK8 Base Front uses the front tire size from the 18-inch staggered setup. Choosing for this position means matching the correct front specification and avoiding the common mistake of using the wider rear size at all four corners.
The 2001 Jaguar XK8 Base Rear uses the wider rear tire size from the 18-inch staggered arrangement. That makes rear tire choice more than a simple duplicate of the front, especially when comparing sidewall appearance and wheel-width compatibility.
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.

Common 2001 Jaguar XK8 tire questions usually come down to identifying the correct wheel setup, understanding the staggered 18-inch fitment, and comparing available radial tire styles, brands, and maintenance considerations before road use.
Tire Size & Fitment
What tire size fits a 2001 Jaguar XK8?
The 2001 Jaguar XK8 uses three primary tire sizes depending on configuration: 245/50R17, 245/45R18, and 255/45R18. The 17-inch Base setup uses 245/50R17, while the 18-inch arrangement uses 245/45R18 in front and 255/45R18 in the rear.
That means the first step is confirming whether the car has 17-inch wheels or the 18-inch staggered setup. An XK8 that has been changed with aftermarket wheels, replacement rims, or a prior owner conversion should be checked at the wheel itself before selecting tires.
What size rim does a 2001 Jaguar XK8 use?
A 2001 Jaguar XK8 uses either a 17-inch or 18-inch rim, depending on the tire size fitted to the car. The 245/50R17 size goes with a 17-inch wheel, while both 245/45R18 and 255/45R18 use 18-inch wheels.
Rim diameter should be confirmed before anything else because a 17-inch tire will not mount on an 18-inch wheel, and the reverse is also true. On cars with the staggered 18-inch setup, front and rear wheel positions should also be verified so the right size goes on the right axle.
Why does the 2001 Jaguar XK8 have more than one tire size?
More than one tire size applies to the 2001 Jaguar XK8 because the car was fitted in more than one wheel arrangement. One setup uses 245/50R17 on 17-inch wheels, while another uses a staggered 18-inch combination with 245/45R18 front tires and 255/45R18 rear tires.
That difference affects more than size alone. It changes wheel diameter, front-to-rear fitment, and the range of available products you can compare. Checking the actual wheel package on the car prevents ordering a tire that matches the model year but not the specific XK8 configuration in front of you.
Choosing the Right Tire
What should I consider when choosing a tire for a 2001 Jaguar XK8?
Start with the exact size and wheel setup on the car, because the 2001 Jaguar XK8 may use a 17-inch single-size arrangement or an 18-inch staggered front-and-rear setup. After that, compare radial construction details such as rim-width range, load specification where stated, and sidewall treatment.
The right choice depends on how the car is used and how you want it to present. A blackwall performance radial keeps a modern look, while raised white letter or redline options can shift the appearance noticeably. Cars with non-original wheels should also be checked for width and clearance before selection.
What sidewall styles are available for 2001 Jaguar XK8 tires?
Sidewall style varies by size and product. In the available 18-inch XK8 selections, blackwall is the most common treatment, and 255/45R18 also appears with raised white letter and redline sidewalls through the Pro-Trac Street Pro III line.
That gives the rear tire fitment a wider appearance choice than a purely blackwall-only lineup. Sidewall style does not change the need to match the correct size, wheel diameter, and axle position, but it can make a meaningful difference if the goal is either a restrained grand-touring look or a more pronounced enthusiast presentation.
What brands offer tires for the 2001 Jaguar XK8?
Available 18-inch tire choices for the 2001 Jaguar XK8 include BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across several g-Force series and the Phenom T/A line, Nitto is represented by the NT555 G2, and Pro-Trac offers Street Pro III options in 255/45R18.
Brand comparison matters most after the correct size is pinned down. Once that is settled, the more useful differences are series type, sidewall presentation, rim-width range, and load figures where stated. Choosing by brand name alone can overlook whether the tire matches the car's actual front or rear fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2001 Jaguar XK8?
A period-style 2001 Jaguar XK8 usually starts with keeping the car on its correct wheel diameter and original fitment layout, whether that means 245/50R17 all around or the 18-inch staggered combination. From there, a blackwall radial generally preserves the cleanest modern grand-touring appearance.
The XK8 belongs to a newer collector era than many classic cars, so appearance tends to come more from proper stance and correct sizing than from vintage-style construction. If originality matters closely, compare the tire's overall look against marque-specific photos and restoration references before settling on a sidewall treatment.
How does tire construction affect the appearance of a restored 2001 Jaguar XK8?
For the 2001 Jaguar XK8, construction choice is straightforward because the primary fitments are radial tires. That keeps the visual character closer to the car's original era, with appearance differences coming more from sidewall treatment, tread style, and whether the car uses the 17-inch or 18-inch wheel setup.
A blackwall radial usually looks the most restrained on this model, while raised white letter or redline sidewalls make a stronger styling statement, especially at the rear in 255/45R18. The cleaner restoration approach is usually to preserve the intended size relationship first, then decide how bold or subtle the sidewall should be.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2001 Jaguar XK8?
Yes. Modifications can affect tire fitment on a 2001 Jaguar XK8, especially if the car has aftermarket wheels, different wheel widths, altered offsets, lowered suspension, or changes in ride height. Those factors matter even when the tire size itself matches one of the original XK8 fitments.
A car with the 18-inch staggered setup should be checked carefully at both axles, since front and rear sizes are different to begin with. Clearance at the fender, suspension, and steering range should be verified on the actual car rather than assumed from the model year alone.
What should I inspect before driving a 2001 Jaguar XK8 on new tires?
Before road use, inspect the wheels for the correct diameter, check that each tire is mounted in the proper front or rear position, and confirm there are no obvious clearance issues. It also helps to look over valve stems, wheel condition, tread seating, and inflation pressure before putting miles on the car.
An XK8 that has spent time parked should also be checked for older suspension wear, alignment issues, or signs that the previous tires rubbed unevenly. A brief low-speed test drive can reveal vibration, pull, or contact problems early, before the car is taken on a longer outing.
How should tires on a collector 2001 Jaguar XK8 be maintained?
Tires on a collector 2001 Jaguar XK8 should be inspected regularly for air loss, uneven wear, sidewall cracking, cuts, bulges, and signs of age-related hardening. Pressure checks matter even on low-mileage cars, since long storage periods can hide a tire that looks acceptable but is no longer road-ready.
Storage conditions also play a role. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps preserve the tires between drives. It is also wise to recheck condition before any highway trip, especially if the XK8 is used only seasonally or sparingly.
