The 2019 Jaguar XJ represents the final years of Jaguar’s long-running aluminum luxury sedan, blending traditional British grand-touring character with modern performance and a distinctly low, sleek profile. Even late in its production run, the XJ stood apart from more upright executive sedans by looking and driving like a flagship meant to cover real road at speed. Tire fitment follows that modern sporting-luxury brief, with radial staggered front and rear sizes in both 19-inch and 20-inch combinations depending on configuration. That gives owners a real choice between wheel packages, tire series, and sidewall presentation in certain 20-inch applications. The key is matching the exact front or rear position and sub-model before comparing tire options.
Which Tire Size Is Right for The 2019 Jaguar XJ
The 2019 Jaguar XJ uses four primary tire sizes across its front and rear positions, with fitment changing by sub-model and wheel package. Some versions use 20-inch front and rear sizes, while others can use 19-inch front and rear sizes, so the first step is confirming both your exact XJ configuration and whether you are selecting a front or rear tire before comparing product choices.
Fit(s): 50 Front, L Portfolio Front, L Supercharged Front, R-Sport Front, and Supercharged Front
Construction: Radial|Rim: 20 in
245/40R20 is a metric radial size in which 245 identifies nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 20 is the rim diameter in inches. On the 2019 Jaguar XJ, this size serves as a front fitment on 20-inch wheel applications, making it part of the car’s staggered setup rather than a universal all-around size. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with Blackwall, RWL, and Redline sidewall treatments appearing in this size. This is the right size to evaluate when your XJ uses the 20-inch front wheel package and you want to compare appearance as well as tire series.
Fit(s): 50 Rear, L Portfolio Rear, L Supercharged Rear, R-Sport Rear, and Supercharged Rear
Construction: Radial|Rim: 20 in
275/35R20 is a metric radial size with a 275-millimeter nominal section width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2019 Jaguar XJ, it is used as the rear companion to the 245/40R20 front size on 20-inch staggered applications, so it should be treated as a position-specific fitment. This size is available from BFGoodrich, Nitto, and Pro-Trac, with Blackwall, RWL, and Redline sidewall choices depending on the tire selected. Owners choosing this size should confirm that the rear wheel setup remains stock in diameter and width before narrowing the field by tire series or sidewall style.
245/45R19 is a metric radial size where 245 is the nominal width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter. On the 2019 Jaguar XJ, this size appears as a front fitment on certain 19-inch wheel applications, again as part of a staggered front and rear arrangement rather than a square setup. BFGoodrich and Nitto options are available here, primarily in Blackwall form across several g-Force and NT555 G2 series choices. This size matters when the car is equipped with the 19-inch front wheel package and the goal is to keep the correct front tire proportions for that setup.
275/40R19 is a metric radial size with a 275-millimeter nominal section width, a 40-series sidewall profile, radial construction, and a 19-inch rim. For the 2019 Jaguar XJ, it serves as the rear fitment paired with 245/45R19 on 19-inch staggered applications, so it is tied to specific sub-model and wheel-package combinations. In this size, BFGoodrich and Nitto products are available, with Blackwall sidewalls and several tire series including g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A. It is the rear size to examine when maintaining the 19-inch staggered setup and comparing available series within that fitment.
Sub-model fitment on the 2019 Jaguar XJ is not one-size-fits-all because front and rear positions are treated separately and some versions use different wheel diameters. Checking the exact sub-model and axle position is the most important step before choosing a tire.

2019 Jaguar XJ tire questions usually come down to front-versus-rear sizing, 19-inch versus 20-inch wheel packages, and choosing among available radial tire series and sidewall styles. The FAQs below focus on exact fitment, product selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2019 Jaguar XJ?
The 2019 Jaguar XJ uses four primary tire sizes: 245/40R20, 275/35R20, 245/45R19, and 275/40R19. These are not interchangeable across the whole car, because the XJ uses staggered front and rear sizing and some sub-models are fitted with 20-inch wheels while others can use 19-inch wheel packages.
Getting the right size starts with identifying both the exact sub-model and the tire position. A front tire and a rear tire may use different widths and aspect ratios, and the wheel diameter must match the tire exactly, so it is important to check the installed wheel setup before selecting a replacement.
What size rim does a 2019 Jaguar XJ use?
The 2019 Jaguar XJ uses either 19-inch or 20-inch rims, depending on the sub-model and wheel package. The 245/40R20 and 275/35R20 sizes are built for 20-inch rims, while the 245/45R19 and 275/40R19 sizes are built for 19-inch rims.
Rim diameter is the first fitment detail to confirm because a 19-inch tire cannot be mounted on a 20-inch wheel, and the reverse is also true. Once diameter is confirmed, the next step is verifying whether the tire is intended for the front or rear axle on the car’s staggered setup.
Why does the 2019 Jaguar XJ have more than one tire size?
The 2019 Jaguar XJ has more than one tire size because fitment varies by sub-model, wheel package, and axle position. It uses a staggered arrangement, with narrower front tires and wider rear tires, and some versions are equipped with 19-inch wheels while others use 20-inch wheels.
That means the correct replacement is not chosen by year, make, and model alone. The practical check is confirming the exact sub-model, then matching the wheel diameter and front or rear position so the replacement tire keeps the intended proportions of the existing setup.
Choosing the Right Tire
What should I consider when choosing a 2019 Jaguar XJ tire?
Start with the exact size, wheel diameter, and axle position used on your 2019 Jaguar XJ. Since the car uses staggered fitment and can be equipped with either 19-inch or 20-inch wheels, the basic decision is making sure the tire matches the car’s actual front or rear setup before comparing brands or series.
Once fitment is confirmed, compare the available tire series, sidewall style, rim-width compatibility, and any load figures shown for that size. A buyer looking for a more understated modern presentation may focus on Blackwall choices, while a more customized look may point toward RWL or Redline options in the 20-inch sizes.
What sidewall styles are available for 2019 Jaguar XJ tires?
Sidewall style depends on the tire size chosen for the 2019 Jaguar XJ. Blackwall is available across all four primary sizes, while RWL and Redline sidewall treatments appear in the 20-inch sizes 245/40R20 and 275/35R20 through Pro-Trac Street Pro III offerings.
That makes sidewall style a real selection factor if the car uses the 20-inch wheel package. Owners with 19-inch fitments are generally comparing tire series within Blackwall options, while 20-inch buyers can weigh a more traditional Blackwall appearance against raised white letter or Redline presentation.
What brands offer tires for the 2019 Jaguar XJ?
Tires for the 2019 Jaguar XJ are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across all four primary sizes, Nitto is also available across all four sizes, and Pro-Trac options are offered in the 20-inch sizes used on certain front and rear applications.
Brand choice matters only after the exact fitment is confirmed. Once the correct front or rear size is established, buyers can compare each brand’s available tire series, sidewall treatment, and wheel-width compatibility to find the option that best suits the XJ’s wheel package and intended appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Jaguar XJ?
Yes, modifications can affect tire fitment on a 2019 Jaguar XJ even when the tire size itself looks correct. Aftermarket wheels, changes in wheel width, suspension lowering, or body alterations can all change how much room is available at the fender, strut, and steering points.
A modified XJ should be checked for actual wheel diameter, wheel width, and clearance at both front and rear before a replacement tire is chosen. That is especially important on this car because the factory setup is staggered, so a change at one axle does not automatically translate to the other.
What should I inspect before driving a 2019 Jaguar XJ on new tires?
Before driving a 2019 Jaguar XJ on new tires, inspect the wheels for the correct diameter and condition, confirm that each tire is mounted in the proper front or rear position, and check inflation pressure. It is also smart to look over the valve stems, wheel hardware, and general tread and sidewall condition.
A short initial drive should be followed by another pressure check and a quick look for rubbing, especially if the car has non-stock wheels or suspension changes. Since the XJ uses staggered sizing, even a small fitment mistake can show up as clearance trouble at one axle but not the other.
What should I check before a longer drive in a 2019 Jaguar XJ?
Before a longer drive in a 2019 Jaguar XJ, check tire pressure, inspect the tread and sidewalls for cuts, bulges, or cracking, and confirm that the correct front and rear sizes are installed. It also helps to verify that the wheels are in good condition and that there is no slow air loss.
Longer trips put more emphasis on stable fitment and consistent tire condition, so it is worth rechecking any car that has sat for extended periods. An XJ with recently changed wheels, suspension parts, or alignment settings deserves an extra clearance and wear-pattern inspection before heading out.
