The 2008 Jaguar XJR blends traditional Jaguar luxury with the sharper edge of a supercharged modern sport sedan, making tire choice more than a simple replacement decision. Owners typically want to preserve the car’s balance of high-speed composure, crisp response, and understated style. This XJR uses radial fitments in two sizes, 255/40R19 and 255/35R20, so the first step is confirming which wheel diameter is on the car. From there, the choice shifts to tire series, brand, and sidewall presentation, including blackwall, redline, and raised white letter options. A careful match helps keep the car’s appearance, stance, and road manners in line with its intended character.
Which Tire Size Is Right for The 2008 Jaguar XJR
The 2008 Jaguar XJR uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. The Base sub-model can use either 255/40R19 or 255/35R20, so confirming whether the car has 19-inch or 20-inch wheels is the first and most important step. Once wheel diameter is verified, the real choice becomes comparing available tire series, sidewall styles, and brand options within the correct size.
A 255/35R20 tire uses a 255-millimeter section width, a 35-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2008 Jaguar XJR, this is the lower-profile of the two primary fitments and suits cars equipped with 20-inch wheels. Available choices include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall treatments depending on the tire series. This size is the right place to focus if the car already wears 20-inch wheels and you want to compare performance-oriented radial options without changing wheel diameter.
A 255/40R19 tire keeps the same 255-millimeter section width but uses a 40-series profile on a 19-inch rim, again in radial construction. For the 2008 Jaguar XJR, this size applies to cars fitted with 19-inch wheels, so wheel confirmation matters before anything else. BFGoodrich and Pro-Trac options are available here, with blackwall, redline, and raised white letter presentations appearing across different tire series. This fitment is the proper path for an XJR on 19-inch wheels when the goal is to stay with the intended rim diameter while comparing style and performance-focused tire choices.
Sub-model fitment is straightforward here because the 2008 Jaguar XJR Base is the covered configuration, but tire choice still depends on wheel diameter. The Base can use either 255/40R19 or 255/35R20, so identifying the actual wheel on the car is essential before selecting a tire.

Tire Size & Fitment
What tire size fits a 2008 Jaguar XJR?
The 2008 Jaguar XJR uses two primary tire sizes: 255/40R19 and 255/35R20. Both are radial fitments, and both apply to the XJR Base depending on which wheel diameter is installed on the car.
That means the tire decision starts with the wheels, not the tread pattern. A 19-inch wheel requires 255/40R19, while a 20-inch wheel requires 255/35R20. Since both sizes share similar overall dimensions but different rim diameters, checking the wheel itself is more important than assuming fitment from appearance alone.
What size rim does a 2008 Jaguar XJR use?
A 2008 Jaguar XJR can use either a 19-inch or 20-inch rim, depending on the tire size fitted to the car. The 255/40R19 size belongs on a 19-inch rim, while the 255/35R20 size belongs on a 20-inch rim.
The wheel diameter must match the tire exactly, so this is the first detail to verify before comparing products. Looking at the wheel marking or the size molded into the current tire is the simplest check. Once the rim diameter is confirmed, attention can shift to sidewall style, tire series, and wheel-width compatibility.
Why does the 2008 Jaguar XJR have more than one tire size?
The 2008 Jaguar XJR has more than one tire size because it was fitted with two different wheel diameters: 19 inches and 20 inches. That creates two correct primary fitments, 255/40R19 and 255/35R20, rather than one universal size for every car.
The practical takeaway is that wheel diameter decides the tire size. Owners should confirm the actual wheel setup on the vehicle, especially if it has changed hands or received aftermarket wheels. Once that is settled, the remaining decision is easier and comes down to choosing among the available radial tires within the matching size.
Choosing the Right Tire
What should I consider when choosing a 255/35R20 tire for a 2008 Jaguar XJR?
A 255/35R20 tire for a 2008 Jaguar XJR should first match the car’s 20-inch wheel setup, then be compared by tire series, sidewall style, and rim-width compatibility. Available choices include BFGoodrich, Nitto, and Pro-Trac products, all in radial construction.
Beyond size, think about the car’s intended use and appearance. Blackwall options keep a more modern presentation, while redline or raised white letter versions change the visual character noticeably. It also helps to compare wheel-width ranges where stated and confirm there is no clearance issue from any non-stock wheel or suspension change.
What sidewall styles are available for 2008 Jaguar XJR tires?
2008 Jaguar XJR tires are available in several sidewall styles, including blackwall, redline, and raised white letter. Those treatments appear across the applicable 255/35R20 and 255/40R19 radial tire choices, giving the car a more contemporary or more visually assertive look depending on the selection.
Sidewall style does not change the need to stay with the correct tire size for the wheel diameter. It is best treated as an appearance decision after fitment is confirmed. Buyers aiming for a subtle factory-inspired look often lean toward blackwalls, while redline or raised white letter choices create a more customized presentation.
What brands offer tires for the 2008 Jaguar XJR?
Tires for the 2008 Jaguar XJR are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. The 255/35R20 fitment includes all three brands, while the 255/40R19 fitment includes BFGoodrich and Pro-Trac options.
Brand should be compared alongside the tire series, sidewall treatment, and wheel compatibility rather than in isolation. Some owners will want a straightforward blackwall performance look, while others may prefer the visual change that comes with redline or raised white letter styles. The right choice depends on the correct size and the character you want from the car.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Jaguar XJR?
A period-style 2008 Jaguar XJR tire choice starts with the correct radial size for the car’s wheel diameter, either 255/40R19 or 255/35R20. From there, a blackwall tire usually keeps the most restrained and era-appropriate look for a super sedan from the late 2000s.
Appearance still has to work with the actual wheel setup on the car. Redline and raised white letter options are available, but they shift the XJR away from a more understated presentation. Buyers focused on originality-sensitive detailing should compare the car against period photos, marque references, or prior ownership history before making a cosmetic change.
How does tire construction affect the appearance of a restored 2008 Jaguar XJR?
Tire construction is simple on the 2008 Jaguar XJR because both primary fitments are radial. That keeps the appearance question centered less on bias-ply versus radial shape and more on sidewall treatment, profile, and the visual relationship between the tire and either the 19-inch or 20-inch wheel.
A blackwall radial usually preserves the cleanest luxury-performance look, while redline or raised white letter versions make the tire stand out more. Since the XJR sits in a modern collector space rather than an early restoration era, visual authenticity often comes down to choosing a tire that complements the car’s original design language instead of chasing novelty.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Jaguar XJR?
Yes, modifications can affect tire fitment on a 2008 Jaguar XJR even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, or body modifications can all alter how a 255/40R19 or 255/35R20 tire sits in the wheel opening.
That is why a modified XJR should be checked for steering clearance, fender clearance, and wheel compatibility before replacing tires. A car that still uses stock wheels is usually more straightforward. On a changed setup, verify the wheel dimensions first, then inspect for rubbing marks or unusually tight clearances at full lock and full suspension travel.
What should I inspect before driving a 2008 Jaguar XJR on new tires?
Before driving a 2008 Jaguar XJR on new tires, inspect the wheels for damage, confirm the tire size matches the rim diameter, and check that each tire seats properly and holds air evenly. It is also smart to look over valve stems, balance, and general suspension condition.
A quick road-use inspection should also include clearance at the inner fender and suspension, especially if the car has non-stock wheels. Uneven wear on the old tires can point to alignment or component issues that should be corrected before the new set sees much use. Proper pressure checks should become part of the routine from the start.
How often should tires on a 2008 Jaguar XJR be inspected?
Tires on a 2008 Jaguar XJR should be inspected regularly, not just when tread looks low. A visual check for cuts, punctures, bulges, cracking, and uneven wear is worthwhile before longer drives, and pressure should be monitored consistently because low-profile performance tires can react quickly to underinflation.
Collector-minded or low-use cars deserve extra attention because age and storage conditions matter as much as mileage. Looking over the tires every month and before highway use is a sensible routine. Any car that has sat for extended periods should also be checked for flat spotting, slow air loss, and wheel or suspension issues before returning to normal road use.
