The 2000 Jaguar XK8 blends grand touring refinement with the sleek, long-hood shape that defined Jaguar’s modern XK line at the turn of the century. It is a car bought as much for smooth high-speed road manners and elegant styling as for outright pace, so tire fitment plays a major role in how the car looks and feels on the road. The 2000 Jaguar XK8 uses radial tire fitments in 245/50R17, 245/45R18, and 255/45R18 depending on wheel position and setup. Available choices include performance-oriented radial series, along with blackwall, raised white letter, and redline sidewall treatments in some 18-inch applications. The key is confirming whether the car remains on its original wheel arrangement before choosing by size, appearance, and intended driving use.
Which Tire Size Is Right for The 2000 Jaguar XK8
The 2000 Jaguar XK8 uses three primary tire sizes, and the right choice depends on the exact wheel setup. The 17-inch Base fitment uses one size, while the 18-inch arrangement uses a staggered combination with one front size and a different rear size. Confirming whether the car is on 17-inch wheels or the 18-inch front-and-rear setup is the first step before comparing brands, tire series, and sidewall style options.
A 245/50R17 tire uses a 245-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2000 Jaguar XK8, this is the radial fitment tied to the 17-inch Base setup, making it the key size for cars that have not been changed to the larger wheel package. Its practical role is straightforward: confirm that the car is still using 17-inch wheels, then select a tire that matches the intended road use and preserves the car’s touring balance.
A 245/45R18 tire keeps the same 245-millimeter nominal width but uses a lower 45-series profile on an 18-inch rim. On the 2000 Jaguar XK8, this size serves the front position in the 18-inch arrangement, so it should be considered as part of a matched front-and-rear setup rather than as a stand-alone universal fitment. Available products in this size come from BFGoodrich and Nitto in blackwall radial performance series, giving buyers room to compare tire character, rim-width specifications, and load details within the correct front size.
A 255/45R18 tire uses a slightly wider 255-millimeter nominal section width, a 45-series profile, radial construction, and an 18-inch rim diameter. On the 2000 Jaguar XK8, this is the rear size for the 18-inch setup, so it works as the companion to the 245/45R18 front fitment rather than as a one-size solution for every car. Choices in this size include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall treatments that can shift the car toward a cleaner modern look or a more customized presentation.
Sub-model fitment matters on the 2000 Jaguar XK8 because the covered configurations do not all use the same tire size. One setup uses a 17-inch tire, while the 18-inch arrangement splits front and rear sizes, so identifying the exact configuration is essential before selecting a tire.

2000 Jaguar XK8 Base
The 2000 Jaguar XK8 Base uses the 245/50R17 radial size, making it the key fitment for cars equipped with the 17-inch wheel setup. Tire selection here centers on confirming that the car still wears 17-inch wheels and then choosing a replacement that suits touring use and the vehicle’s overall presentation.
The 2000 Jaguar XK8 Base Front uses the 245/45R18 radial size as part of the 18-inch arrangement. That means front tire choice should be made alongside the matching rear size, with attention to maintaining the intended staggered setup and checking wheel compatibility before changing brands or tire series.
The 2000 Jaguar XK8 Base Rear uses the 255/45R18 radial size in the 18-inch setup. Rear tire selection should stay tied to the proper front-and-rear pairing, while buyers compare sidewall treatments, tire series, and wheel specifications that suit the car’s current wheels and intended 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.

These 2000 Jaguar XK8 tire FAQs focus on size identification, 17-inch versus 18-inch fitment, staggered front-and-rear setups, available brands and sidewall styles, and the wheel, suspension, and maintenance checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2000 Jaguar XK8?
A 2000 Jaguar XK8 can use 245/50R17, 245/45R18, or 255/45R18 depending on the wheel setup and position. The 17-inch Base configuration uses 245/50R17, while the 18-inch arrangement uses 245/45R18 in front and 255/45R18 in the rear.
That makes wheel confirmation the first step before buying tires. A car still on 17-inch wheels needs the 245/50R17 size, while a car on the 18-inch setup should keep the front and rear sizes in their proper positions. If the XK8 has changed wheels over time, measure the current rims and check the existing tire sizes before selecting replacements.
What size rim does a 2000 Jaguar XK8 use?
The 2000 Jaguar XK8 uses either a 17-inch or 18-inch rim, depending on the tire size and configuration. The 245/50R17 fitment belongs to a 17-inch rim, while both 245/45R18 and 255/45R18 are built for 18-inch rims.
That distinction matters because tire diameter at the bead must match wheel diameter exactly. A 17-inch tire cannot be mounted on an 18-inch wheel, and the 18-inch front-and-rear setup also requires keeping the correct sizes in the correct positions. If the car has aftermarket wheels, verify the wheel size stamped on the rim rather than relying only on appearance.
Why does the 2000 Jaguar XK8 have more than one tire size?
The 2000 Jaguar XK8 has more than one tire size because it appears in more than one wheel arrangement. One setup uses a single 17-inch size, while the 18-inch arrangement uses a staggered fitment with 245/45R18 in front and 255/45R18 in the rear.
That means the correct tire choice depends on how the car is equipped right now, not just on the model name. On an 18-inch XK8, the front and rear sizes work together as a matched setup, so replacing only one position with the wrong size can upset the intended balance. Confirm wheel diameter and current front-versus-rear sizing before ordering replacements.
Choosing the Right Tire
What should I consider when choosing a tire for a 2000 Jaguar XK8?
Start with the exact tire size and wheel arrangement on the car. A 17-inch XK8 uses 245/50R17, while the 18-inch setup uses 245/45R18 in front and 255/45R18 in the rear, so the first decision is always matching the tire to the actual wheel diameter and position.
After that, compare construction, brand, tire series, sidewall appearance, and wheel-width compatibility where those details are available. The 18-inch products lean toward modern radial performance offerings, and the rear 255/45R18 size adds visual choices such as blackwall, raised white letter, and redline. Pick the combination that suits the car’s look, intended mileage, and current wheel setup.
What sidewall styles are available for 2000 Jaguar XK8 tires?
Sidewall style depends on the size you are shopping. In the available 18-inch fitments, 245/45R18 appears in blackwall form, while 255/45R18 includes blackwall, raised white letter, and redline choices.
That gives the rear 18-inch size a wider appearance range than the front. A blackwall keeps the presentation clean and understated, while raised white letter or redline treatments create a more customized visual effect. Match sidewall style to the way the XK8 is being presented, and make sure any front-and-rear selection still respects the correct size placement on staggered 18-inch cars.
What brands offer tires for the 2000 Jaguar XK8?
Available 18-inch tire choices for the 2000 Jaguar XK8 include BFGoodrich, Nitto, and Pro-Trac. BFGoodrich and Nitto appear in both 245/45R18 and 255/45R18, while Pro-Trac appears in the 255/45R18 rear size with more than one sidewall treatment.
Brand choice should be considered alongside size, wheel position, and the character of the tire series rather than in isolation. The useful comparison points here are whether the tire is for the front or rear of the 18-inch setup, what sidewall style it carries, and whether the wheel-width range and load details suit the car’s current wheels and intended driving use.
Restoration & Appearance
Which tire should I choose for a period-style 2000 Jaguar XK8?
A period-style 2000 Jaguar XK8 tire choice starts with keeping the correct size and wheel arrangement for the car as equipped. That means 245/50R17 for the 17-inch setup, or the paired 245/45R18 front and 255/45R18 rear sizes for the 18-inch arrangement.
Once the sizing is right, appearance becomes the deciding factor. Blackwall options usually preserve the clean grand touring look most buyers associate with this era, while some 255/45R18 offerings add redline or raised white letter styling for a more personalized presentation. If exact originality matters, compare the car’s current setup with marque-specific references before making a final visual choice.
How does tire construction affect the appearance of a restored 2000 Jaguar XK8?
On the 2000 Jaguar XK8, the primary fitments are radial tires, so the appearance discussion is less about bias-ply versus radial and more about profile, wheel size, and sidewall presentation. A 17-inch setup gives the car one visual stance, while the staggered 18-inch arrangement creates a different look.
Sidewall treatment then becomes the main styling lever within the available products. Blackwall tires keep the presentation restrained, while redline or raised white letter versions in 255/45R18 move the car toward a more customized look. For a restoration-minded XK8, preserving the proper size relationship is usually more important than chasing a dramatic sidewall style that changes the car’s overall character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2000 Jaguar XK8?
Yes, modifications can affect tire fitment on a 2000 Jaguar XK8 even when the tire size looks close to the original setup. Wheel diameter, wheel width, offset changes, suspension alterations, and ride-height changes can all alter clearance at the fender, inner wheelhouse, and steering components.
That matters most on cars using the staggered 18-inch arrangement, where front and rear sizes already differ by design. If the XK8 has aftermarket wheels or suspension changes, verify the actual wheel dimensions and inspect clearance at full steering lock and through suspension travel. A correct size on paper still needs to work with the car’s real-world wheel and body setup.
What should I inspect before driving a 2000 Jaguar XK8 on new tires?
Before driving a 2000 Jaguar XK8 on new tires, inspect tire pressure, wheel fastener torque, tread and sidewall condition, and the seating of each tire on the rim. It is also smart to confirm that the sizes are correctly placed, especially on an 18-inch car that uses 245/45R18 in front and 255/45R18 in the rear.
A short initial road test should include listening for rubbing, feeling for vibration, and checking that the car tracks normally. After a few miles, recheck pressures and look for any signs of contact near the suspension or wheel openings. Low-use grand touring cars can hide age-related issues, so the rest of the chassis should be in sound condition before regular road use resumes.
What should I check before a longer drive in a 2000 Jaguar XK8?
Before a longer drive, make sure the 2000 Jaguar XK8 is wearing the correct tire sizes for its current wheel setup and that all four tires are in sound condition. Check air pressure, inspect for cracking, cuts, bulges, or irregular wear, and confirm that front and rear sizes are not mixed on a staggered 18-inch car.
Longer highway use also puts more importance on wheel balance and general suspension health. A tire can be the right size and still feel unsettled if worn shocks, alignment issues, or aged bushings are present. Collector and fair-weather cars deserve an extra inspection because low annual mileage often hides age and storage effects that matter once the car returns to sustained road use.
