The 2011 Jaguar XK sits in the modern grand touring tradition, pairing long-hood Jaguar styling with the kind of speed and refinement that make tire choice more than a routine maintenance item. On this car, fitment centers on staggered radial sizes, with different front and rear tire dimensions and either 19-inch or 20-inch wheel packages depending on the setup. That means the first decision is confirming which wheel diameter is on the car before choosing among the correct sizes. Available options range from blackwall performance radials to raised white letter and redline treatments on certain 20-inch sizes, so appearance and driving use both matter.
Which Tire Size Is Right for The 2011 Jaguar XK
The 2011 Jaguar XK uses four primary tire sizes, and the correct combination depends on whether the car has the 19-inch or 20-inch staggered wheel setup. Front and rear sizes are different, so the first step is confirming both the wheel diameter and whether you are selecting for the front axle or rear axle before comparing brands, sidewall styles, and tire series.
A 245/40R19 tire uses a 245-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 19-inch rim. On the 2011 Jaguar XK, this size serves the front position on the 19-inch staggered setup, making it part of the car's primary handling balance rather than a universal fit across all wheel packages. Available choices in this size center on BFGoodrich blackwall radials, including g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A. This size should be evaluated when the car retains its 19-inch front wheels and the buyer wants to compare tire series within that exact fitment.
A 255/35R20 tire is a metric radial with a 255-millimeter nominal section width, a 35-series profile, and a 20-inch rim diameter. On the 2011 Jaguar XK, it is the front size for the 20-inch staggered arrangement, so it belongs with the matching 20-inch rear fitment rather than the 19-inch setup. Product choices include BFGoodrich and Nitto blackwall tires, along with Pro-Trac Street Pro III versions in raised white letter and redline form. This size makes sense when the car is equipped with 20-inch front wheels and the buyer wants either a conventional blackwall look or a more customized sidewall presentation.
A 275/35R19 tire combines a 275-millimeter nominal section width with a 35-series profile, radial construction, and a 19-inch rim. For the 2011 Jaguar XK, this is the rear companion to the 245/40R19 front size on the 19-inch staggered package, so its role is tied directly to the correct rear-wheel fitment. BFGoodrich and Nitto options are available here in blackwall performance-oriented radial lines, including multiple g-Force series and the NT555 G2. This size should be considered when the car remains on its 19-inch rear wheels and the goal is to keep the intended front-to-rear size relationship intact.
A 285/30R20 tire uses a 285-millimeter nominal section width, a low 30-series profile, radial construction, and a 20-inch rim. On the 2011 Jaguar XK, it serves the rear position for the 20-inch staggered setup, matching the 255/35R20 front size rather than the 19-inch package. Available products include Nitto in blackwall form and Pro-Trac Street Pro III with raised white letter or redline sidewalls, giving this size some visual variety beyond a standard modern performance look. It is the right size to evaluate when the car has 20-inch rear wheels and the buyer wants to balance proper fitment with a specific appearance.
Fitment on the 2011 Jaguar XK is straightforward in one sense and very specific in another: the car uses separate front and rear sizes, with either a 19-inch or 20-inch staggered setup. Checking whether you are replacing front or rear tires, and confirming wheel diameter, matters before choosing any tire.

2011 Jaguar XK Base Front
The 2011 Jaguar XK Base Front uses one of two front radial sizes depending on whether the car is equipped with the 19-inch or 20-inch wheel package. That makes front-tire selection a matter of matching the wheel diameter first, then comparing the available tire series and sidewall treatments within the correct size.
The 2011 Jaguar XK Base Rear also has two possible radial sizes, tied to either the 19-inch or 20-inch staggered arrangement. Rear-tire choice should stay matched to the corresponding front setup so the car keeps the intended front-to-rear fitment relationship and proper wheel 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.
Best 2011 Jaguar XK Tires for Sale
Available 2011 Jaguar XK tires span all four primary radial sizes, with BFGoodrich, Nitto, and Pro-Trac offerings in several performance-oriented series. Most choices are blackwall, while selected 20-inch sizes also add raised white letter and redline sidewall options for a more custom presentation.
Common 2011 Jaguar XK tire questions usually come down to staggered front and rear sizing, 19-inch versus 20-inch wheel fitment, and how to compare the available radial tire lines and sidewall treatments. The answers below focus on practical fitment, selection, and road-use checks for this exact model.
Tire Size & Fitment
What tire size fits a 2011 Jaguar XK?
The 2011 Jaguar XK uses staggered radial tire sizes rather than one uniform fitment. The 19-inch setup uses 245/40R19 in front and 275/35R19 in the rear, while the 20-inch setup uses 255/35R20 in front and 285/30R20 in the rear.
The important step is confirming which wheel package is actually on the car before ordering tires. Front and rear sizes are different, so replacing only one axle or mixing sizes from the 19-inch and 20-inch packages can create an incorrect setup unless the full wheel and tire combination has been intentionally changed.
What size rim does a 2011 Jaguar XK use?
A 2011 Jaguar XK uses either 19-inch or 20-inch rims, depending on the wheel package. The 245/40R19 and 275/35R19 sizes mount on 19-inch wheels, while the 255/35R20 and 285/30R20 sizes mount on 20-inch wheels.
Rim diameter should be verified directly at the car before selecting tires, especially if the wheels may have been changed at some point. Once the diameter is confirmed, the next step is matching the correct front and rear size pair, since this Jaguar uses a staggered arrangement rather than the same tire size at all four corners.
Why does the 2011 Jaguar XK have more than one tire size?
The 2011 Jaguar XK has more than one tire size because it uses staggered fitment and was offered with different wheel diameters. Front tires are narrower than rear tires, and the exact sizes change between the 19-inch and 20-inch wheel setups.
That means the tire decision starts with the car's actual configuration, not just the year, make, and model. Looking at the wheel diameter and whether the tire is for the front or rear position helps narrow the correct size quickly, while also preventing mix-ups between the 19-inch package and the 20-inch package.
Choosing the Right Tire
What should I consider when choosing a 2011 Jaguar XK tire?
Start with the exact axle position and wheel diameter, because the 2011 Jaguar XK uses staggered front and rear radial sizes in both 19-inch and 20-inch combinations. After size is confirmed, compare the available tire series, construction details, and any rim-width specifications that apply to that size.
Appearance can also shape the decision, especially in the 20-inch sizes where blackwall, raised white letter, and redline options are available. A buyer keeping a clean modern grand touring look may lean one way, while a more customized presentation may point to another, provided the tire still matches the car's actual wheel and axle fitment.
What sidewall styles are available for 2011 Jaguar XK tires?
Blackwall is the most common sidewall style available for the 2011 Jaguar XK across its primary tire sizes. Selected 20-inch sizes also offer raised white letter and redline versions, giving the car a more custom look without changing the underlying tire size.
Sidewall style should be chosen after the correct fitment is settled, not before. A 19-inch setup largely centers on blackwall performance radials, while the 20-inch front and rear sizes open up more visual variety, so the final choice often comes down to whether the car is being kept understated or given a stronger period-inspired accent.
What brands offer tires for the 2011 Jaguar XK?
Tires for the 2011 Jaguar XK are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich covers several of the 19-inch and 20-inch fitments, Nitto appears in both 19-inch and 20-inch rear and front applications, and Pro-Trac is available in selected 20-inch sizes.
Brand choice works best as a second-step decision after the exact size is confirmed. Once the correct front or rear fitment is established, comparing brand offerings alongside tire series and sidewall style helps narrow the selection, particularly on the 20-inch package where appearance choices are broader than on the 19-inch setup.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Jaguar XK?
A period-style approach on a 2011 Jaguar XK usually starts with keeping the proper staggered size and wheel diameter already on the car. From there, blackwall radials preserve a clean contemporary luxury-performance appearance, while selected 20-inch sizes also open the door to more expressive sidewall treatments.
Because this is a modern-era Jaguar rather than a mid-century restoration project, the visual decision is less about strict originality and more about preserving the car's character. Staying with the correct front and rear size pairing matters more than chasing a particular look, since proportion and stance play a big role in how the XK presents.
How does tire construction affect the appearance of a restored 2011 Jaguar XK?
On the 2011 Jaguar XK, tire construction does not create a bias-ply-versus-radial appearance question because the primary fitments are radial. The visible difference comes more from sidewall treatment and profile, especially when comparing standard blackwall tires with raised white letter or redline options in certain 20-inch sizes.
That makes correct size and wheel pairing the foundation of the car's appearance. An XK on the proper staggered setup will usually look more coherent than one wearing mismatched diameters or incorrect front-to-rear sizing, even before sidewall style enters the decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Jaguar XK?
Yes, modifications can affect tire fitment on a 2011 Jaguar XK, especially because the car already uses staggered front and rear sizes. Aftermarket wheels, suspension changes, altered ride height, or non-original offsets can all change the space available for the tire even when the rim diameter remains 19 or 20 inches.
Checking wheel width, offset, and clearance at full steering lock and suspension movement is a smart step before changing tires on a modified car. That matters even more if the XK no longer has its original wheel package, since the correct factory size pair may not automatically suit a custom setup.
What should I inspect before driving a 2011 Jaguar XK on new tires?
Before driving a 2011 Jaguar XK on new tires, inspect basic condition items around the wheel and tire package. Tire pressure, valve stems, wheel condition, alignment-related wear, and proper front-to-rear size placement all deserve attention on a staggered setup like this one.
A short initial drive followed by a recheck can help confirm everything has seated and balanced properly. It is also worth looking for any rubbing, vibration, or uneven stance that could point to wheel, suspension, or installation issues, particularly if the car has different wheels than it left the factory with.
What should I check before a longer drive in a 2011 Jaguar XK?
Before a longer drive, make sure the 2011 Jaguar XK has the correct front and rear tire sizes for its wheel package and that all four tires are in sound condition. Pressure, tread condition, sidewall damage, and any signs of irregular wear should be checked before relying on the car for highway use.
Collector and low-mileage cars deserve extra attention because age can matter as much as tread depth. A longer trip is also a good reason to confirm there is no air loss, no vibration at speed, and no clearance issue under load, especially if the XK has aftermarket wheels or suspension changes.
