The 2001 Jaguar XJR sits in the supercharged sport-luxury sedan era when Jaguar blended traditional XJ elegance with markedly sharper performance. It is a car that still appeals to owners who want long-wheelbase comfort without losing the urgency and stance that defined the XJR name at the turn of the century. Tire selection for the 2001 Jaguar XJR centers on one primary fitment, a 255/40R18 radial on an 18-inch wheel. Available choices stay within that modern performance-oriented size, with BFGoodrich options in several g-Force series and a blackwall presentation. The real decision is matching the correct 18-inch fitment to the car's intended road use, wheel setup, and overall character.
Which Tire Size Is Right for The 2001 Jaguar XJR
The 2001 Jaguar XJR uses one primary tire size: 255/40R18 radial on an 18-inch rim. That same size carries across the covered XJR Base model, so the main decision is not choosing between multiple factory fitments but selecting the right tire within that size based on wheel compatibility, product series, and the kind of driving the car actually sees.
In 255/40R18, the 255 measures nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. This is a modern low-profile radial size that suits the 2001 Jaguar XJR's performance-luxury character and keeps tire selection centered on 18-inch fitment. Available choices in this size include BFGoodrich options from the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, all in blackwall form. The key is choosing a tire that matches the car's wheel width, expected use, and overall setup rather than treating every 255/40R18 the same.
Fitment is straightforward on the 2001 Jaguar XJR because the covered sub-model uses the same primary tire size. Checking the sub-model still matters because it confirms that tire selection stays focused on the correct 18-inch radial fitment rather than a different XJ variant.

Best 2001 Jaguar XJR Tires for Sale
Available 255/40R18 choices for the 2001 Jaguar XJR come from BFGoodrich across several g-Force series, all in blackwall radial construction. The main product differences to compare are tire series, load-related specifications where stated, and shared rim-width compatibility in the 8.5- to 10-inch range.
These FAQs focus on the exact tire size used on the 2001 Jaguar XJR, what that 18-inch fitment means, how to compare the available BFGoodrich options, and what to inspect before putting a performance sedan back on the road.
Tire Size & Fitment
What tire size fits a 2001 Jaguar XJR?
The 2001 Jaguar XJR uses a 255/40R18 radial tire. That is the primary fitment for this model, and it places the car on an 18-inch wheel with a modern low-profile metric radial size rather than an older numeric or alphanumeric sizing format.
Using the correct size is the starting point, but it is still important to confirm the actual wheel setup on the car. A previous owner may have changed wheels or suspension, and those changes can affect clearance, tire profile, and how comfortably a 255/40R18 works on the vehicle.
What size rim does a 2001 Jaguar XJR use?
The 2001 Jaguar XJR uses an 18-inch rim diameter with its 255/40R18 tire fitment. Among the available tires in this size, the supported rim-width range is 8.5 to 10 inches, which is an important compatibility point when comparing replacement options.
Rim diameter needs to match exactly, but width matters too. An 18-inch wheel that falls outside the tire's approved width range can affect sidewall shape and overall fitment, so measuring the actual wheel before ordering is worthwhile, especially on a car that may have aftermarket wheels.
Does the 2001 Jaguar XJR Base use the same tire size?
Yes. The 2001 Jaguar XJR Base uses the same 255/40R18 radial size. That makes fitment simpler because the main choice is not between different original sizes but between different tire lines offered within the same size and wheel diameter.
Even with shared fitment, the car itself should still be checked before replacement. Wheel changes, alignment issues, or altered ride height can influence how a new tire sits in the wheelwell, so verifying the existing setup helps keep the replacement focused on the correct 18-inch configuration.
Choosing the Right Tire
What should I consider when choosing a 255/40R18 tire for a 2001 Jaguar XJR?
Start with the correct 255/40R18 size and confirm that the wheel diameter and width match the tire's requirements. On this Jaguar, available choices stay within radial blackwall performance tires, so the meaningful comparison points become tire series, weight, and any stated load-related specification.
A car used mainly for fair-weather touring may lead to a different choice than one driven more aggressively or more often. Matching the tire to the XJR's actual use, while checking wheel compatibility and overall condition of the suspension and alignment, gives a more useful result than picking by size alone.
What brands offer tires for the 2001 Jaguar XJR?
The available 255/40R18 fitments for the 2001 Jaguar XJR are from BFGoodrich. Within that brand, the choices include several g-Force series, so the brand decision is straightforward while the real comparison happens between different performance-oriented tire lines in the same size.
That kind of product spread shifts attention toward specifications and intended use rather than logo preference. Looking at rim-width compatibility, load figures where shown, and the role each g-Force series plays will be more helpful than treating all 255/40R18 tires from one brand as effectively identical.
What tire series are available for the 2001 Jaguar XJR?
The 2001 Jaguar XJR's 255/40R18 fitment is available in BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. All are radial blackwall tires, but they are distinct series rather than the same tire sold under slightly different names.
Choosing among them comes down to comparing the details that matter for your car and driving style. Pay attention to wheel-width compatibility, any stated load specification, and whether the tire's overall character fits a road-driven sport sedan, a lower-mileage collector car, or a mix of both.
Restoration & Appearance
Which tire should I choose for a period-style 2001 Jaguar XJR?
A period-style approach for a 2001 Jaguar XJR starts with retaining the correct 255/40R18 radial size and the car's 18-inch wheel fitment. Since the available tires are blackwall BFGoodrich performance radials, the appearance stays modern and understated rather than shifting toward a vintage sidewall treatment.
That makes the decision more about preserving the XJR's turn-of-the-century sport-sedan presentation than recreating an older restoration look. Keeping the proper size, profile, and overall stance usually matters more here than chasing decorative sidewall details that do not suit the model's original era and character.
Does correct tire fitment matter for a 2001 Jaguar XJR restoration?
Yes, correct tire fitment matters because size and profile have a strong effect on how a 2001 Jaguar XJR sits, steers, and visually fills the wheel openings. Staying with the proper 255/40R18 radial size helps preserve the car's intended performance-luxury balance and overall presentation.
Restoration-minded owners should think beyond tread alone and confirm that the wheel diameter, wheel width, and ride height remain consistent with the car's expected setup. Even subtle departures can change the XJR's stance, so fitment accuracy plays a meaningful role in both appearance and road manners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2001 Jaguar XJR?
Yes. Modifications can change how a 255/40R18 tire works on a 2001 Jaguar XJR, even when the size itself is correct. Aftermarket wheels, altered offset, suspension lowering, and worn components can all affect clearance at the fender, inner wheelhouse, and steering range.
That is why a modified car should be checked as it actually sits, not just by the original tire size. Measuring wheel width and inspecting clearance at full lock and full suspension travel can prevent fitment surprises that would not appear on a stock-height XJR with stock-style wheel dimensions.
What should I inspect before driving a 2001 Jaguar XJR on new tires?
Before road use, inspect wheel condition, verify tire pressure, and confirm that the tires are mounted on the correct 18-inch rims. It is also smart to look over the alignment-related wear pattern on the old tires, because uneven wear can point to issues that should be corrected before the new set goes into service.
The rest of the check should include suspension and steering condition, especially on a performance sedan that places real demands on front-end components. A quick review of brake condition and adequate fender and steering clearance helps ensure the new tires are supported by a vehicle that is ready to use them properly.
How should 255/40R18 tires on a collector 2001 Jaguar XJR be maintained?
Collector use does not eliminate maintenance needs. A 255/40R18 tire on a 2001 Jaguar XJR should be checked regularly for pressure loss, tread wear, sidewall cracking, bulges, and cuts, especially if the car is driven infrequently and spends long periods parked between outings.
Storage conditions matter as much as mileage on many low-use cars. Keeping the XJR away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition, while periodic inspections catch aging issues that may not be obvious until the car is driven at highway speed.
