The 2018 Jaguar XF sits in the modern luxury sport-sedan category, blending Jaguar’s traditional long-hood, rear-drive character with contemporary ride, handling, and technology expectations. It is a car that rewards attention to stance and wheel package because tire choice shapes both the look and the way the chassis responds. The 2018 Jaguar XF uses radial tires, with fitments in 245/45R18, 245/40R19, and 255/35R20 depending on sub-model and wheel setup. Available choices range from touring-oriented and performance-oriented radial series to blackwall, raised white letter, and redline presentations in certain sizes. The key is matching the exact sub-model and wheel diameter before comparing style, series, and road-use priorities.
Which Tire Size Is Right for The 2018 Jaguar XF
Three tire sizes apply to the 2018 Jaguar XF, and the right one depends on the exact sub-model and wheel diameter. This is a radial-only fitment spread across 18-inch, 19-inch, and 20-inch rims, so the first step is confirming which wheels are on the car. Once that is settled, the real choice becomes comparing the available radial tire series, sidewall styles, and product specifications within the correct size.
245/45R18 is a modern metric radial size in which 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2018 Jaguar XF, this size supports the 18-inch wheel fitment used on specific sub-models. Available choices include BFGoodrich and Nitto products in blackwall form, with several g-Force series alongside the NT555 G2. This size makes the most sense when the car retains its 18-inch wheel package and the goal is to compare performance-oriented radial options without moving away from the original rim diameter.
245/40R19 follows the same modern metric radial format, with a 245-millimeter nominal section width, a 40-series profile, radial construction, and a 19-inch rim. For the 2018 Jaguar XF, this size belongs to certain sub-models equipped with 19-inch wheels rather than the 18-inch or 20-inch packages. BFGoodrich offers this size across multiple g-Force series, all with blackwall styling, giving buyers a meaningful choice in tire character while staying within the proper fitment family. It is the size to evaluate when the car already wears 19-inch wheels and tire selection is centered on series differences rather than sidewall appearance.

Construction: Radial|Rim: 20 in
255/35R20 is a lower-profile modern metric radial size, with 255 denoting nominal section width in millimeters, 35 as the aspect ratio, R for radial construction, and 20 for the wheel diameter. On the 2018 Jaguar XF, this fitment is tied to 20-inch wheel applications and appears across several upper trims and Sportbrake variants. Product choice is broader here, with BFGoodrich, Nitto, and Pro-Trac options, plus blackwall, raised white letter, and redline sidewall treatments. This size deserves careful attention when appearance matters as much as fitment, especially on cars where the 20-inch wheel package is part of the overall visual statement.
Tire fitment for the 2018 Jaguar XF varies by sub-model, and some trims use more than one wheel-and-tire package. Confirming the exact trim and wheel diameter matters before selecting a tire, because the XF range spans 18-inch, 19-inch, and 20-inch radial fitments.

2018 Jaguar XF Base
The 2018 Jaguar XF Base uses the 245/45R18 radial fitment. Tire selection here is mainly about staying with the correct 18-inch size while comparing the available blackwall radial series and confirming that the car still has its original wheel diameter.
The 2018 Jaguar XF Portfolio can use either a 245/40R19 or 255/35R20 radial tire, depending on wheel package. That makes wheel confirmation the first step, followed by a comparison of the available 19-inch or 20-inch radial options and their sidewall presentation.
The 2018 Jaguar XF Premium uses the 245/45R18 radial size. With fitment straightforward at the size level, the decision shifts to comparing brands and series within the 18-inch group and checking that wheel width remains appropriate for the tire being considered.
The 2018 Jaguar XF Prestige is associated with 245/40R19 and 255/35R20 radial fitments. Choosing correctly means identifying which wheel package is on the car first, then narrowing the selection by tire series, sidewall style, and 19-inch versus 20-inch compatibility.
The 2018 Jaguar XF R-Sport uses either 245/40R19 or 255/35R20 radial tires depending on wheel setup. Buyers should verify the actual rim diameter on the car before comparing products, since both fitments are legitimate but they are not interchangeable across different wheel sizes.
The 2018 Jaguar XF S uses the 255/35R20 radial fitment. That puts the focus on selecting among the broader 20-inch product assortment, including differences in brand, tire series, and whether a blackwall, raised white letter, or redline appearance suits the car.
The 2018 Jaguar XF Sportbrake First Edition uses the 255/35R20 radial size. Tire choice is therefore less about fitment uncertainty and more about selecting the right 20-inch radial product for the wagon’s intended appearance and road use while confirming wheel compatibility.
The 2018 Jaguar XF Sportbrake S also uses the 255/35R20 radial fitment. Buyers can focus on the available 20-inch choices and compare series and sidewall styles, while still checking that the wheel setup has not been changed from the configuration the tire size requires.
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 2018 Jaguar XF Tires for Sale
Available 2018 Jaguar XF tire choices are all radial, with BFGoodrich, Nitto, and Pro-Trac options across the 18-inch, 19-inch, and 20-inch fitments. The main differences are tire series, blackwall versus raised white letter or redline presentation on certain 20-inch options, and rim-width compatibility within each size.
Owners shopping tires for a 2018 Jaguar XF usually need to sort out trim-specific size, wheel diameter, available radial choices, sidewall styling, and a few practical checks before installation or road use.
Tire Size & Fitment
What tire size fits a 2018 Jaguar XF?
A 2018 Jaguar XF can use 245/45R18, 245/40R19, or 255/35R20, depending on the sub-model and wheel package. All three are radial fitments, and they correspond to three different wheel diameters rather than one universal size across the full XF range.
The practical next step is to confirm the exact trim and the actual wheels on the car before comparing tires. A Base or Premium model uses 245/45R18, while other trims may use 19-inch or 20-inch packages. If the car has been fitted with different wheels since new, the tire decision should follow the current wheel diameter and compatible width.
What size rim does a 2018 Jaguar XF use?
The 2018 Jaguar XF uses 18-inch, 19-inch, or 20-inch rims, depending on sub-model and tire size. The 245/45R18 fitment uses an 18-inch rim, 245/40R19 uses a 19-inch rim, and 255/35R20 uses a 20-inch rim.
Rim diameter is the first thing to verify because these tire sizes do not cross over from one wheel size to another. After diameter, wheel width also matters when narrowing the product choice, since the available tires in these sizes are intended for different rim-width ranges. Looking at the wheel itself is often more useful than relying on trim assumptions alone.
Why does the 2018 Jaguar XF have more than one tire size?
The 2018 Jaguar XF has more than one tire size because the model range was offered with different wheel packages across its various trims. Some sub-models use 18-inch wheels, some use 19-inch or 20-inch wheels, and a few trims can be associated with more than one factory-style fitment.
That means tire selection starts with identifying the exact sub-model and then confirming the wheels currently on the car. A Portfolio, Prestige, or R-Sport may be running either 19-inch or 20-inch tires, while an S or Sportbrake variant uses the 20-inch fitment. Choosing by model name alone can lead to the wrong diameter, even when the overall vehicle is still a 2018 XF.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Jaguar XF?
Start with the correct size for the exact 2018 Jaguar XF sub-model and wheel diameter: 245/45R18, 245/40R19, or 255/35R20. From there, compare radial tire series, sidewall style, rim-width compatibility, and useful product details such as load figures where they are available.
The right choice depends on how the car is used and how the owner wants it to look. A blackwall tire keeps a clean modern presentation, while certain 20-inch options also introduce raised white letter or redline styling. It also helps to confirm that the wheel width matches the tire’s intended range so the selected tire suits both the car’s appearance and its wheel setup.
What sidewall styles are available for 2018 Jaguar XF tires?
Blackwall is the most common sidewall style available for the 2018 Jaguar XF, covering the 18-inch and 19-inch fitments and many 20-inch options as well. In 255/35R20, there are also raised white letter and redline choices through the Pro-Trac Street Pro III series.
That gives 20-inch XF owners a more appearance-driven decision than buyers using the smaller wheel packages. Sidewall style does not replace the need to match the correct tire size, but it can change the car’s visual character noticeably. Choosing between blackwall, raised white letter, and redline is easiest after wheel diameter and trim-specific fitment have already been confirmed.
What brands offer tires for the 2018 Jaguar XF?
Tires for the 2018 Jaguar XF are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across all three XF fitments, Nitto is available in 245/45R18 and 255/35R20, and Pro-Trac appears in the 255/35R20 size.
Brand choice should still come after size and wheel confirmation, since not every brand is offered in every XF fitment. Once the correct tire size is established, the comparison becomes more useful because it can focus on tire series, sidewall treatment, and wheel-width compatibility instead of trying to make one brand work across an incorrect wheel diameter.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Jaguar XF?
A period-style approach on a 2018 Jaguar XF usually means keeping the correct original-size radial fitment for the car’s wheel package rather than changing diameter for appearance alone. That could mean 245/45R18, 245/40R19, or 255/35R20 depending on the trim and wheel setup.
For a clean, contemporary luxury-sport look, blackwall tires are the most natural visual match across the XF range. Owners of 20-inch cars who want a more customized presentation may also consider raised white letter or redline options. When originality matters closely, it helps to verify the vehicle’s delivered wheel-and-tire configuration before selecting purely by style.
Does correct tire fitment matter for a 2018 Jaguar XF restoration or cosmetic refresh?
Correct tire fitment matters on a 2018 Jaguar XF because wheel diameter and tire profile are a visible part of the car’s stance. The XF uses three distinct metric radial sizes, and choosing the wrong one can alter the visual balance even before any handling or clearance issue appears.
A cosmetic refresh works best when the tire size matches the wheel package the car is actually wearing. That is especially important on trims that could use either 19-inch or 20-inch fitments, where sidewall height and overall presentation differ. Keeping the right size in place gives the owner freedom to focus on brand, series, and sidewall appearance without creating an avoidable fitment mismatch.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Jaguar XF?
Yes, modifications can affect tire fitment on a 2018 Jaguar XF. Wheel changes, altered wheel width, different offsets, lowered suspension, or body modifications can all change how a 245/45R18, 245/40R19, or 255/35R20 tire sits in the wheelwell and how much clearance it has during steering and suspension travel.
That matters even when the tire size itself is correct for some version of the XF. A car with aftermarket wheels may need a closer check of rim width and clearance than a stock example. Verifying wheel diameter, wheel width, and space at the fender and suspension is a smart step before mounting new tires on any modified sedan or Sportbrake.
What should I inspect before driving a 2018 Jaguar XF on new tires?
Before driving a 2018 Jaguar XF on new tires, inspect the wheel diameter and tire size match, confirm proper inflation, and check that each tire clears the suspension, inner fender, and bodywork. It is also wise to look over the wheels for damage and make sure valve stems and balancing were handled correctly.
A short first drive should include attention to vibration, pull, rubbing, or any unusual steering response. After a few miles, recheck inflation and visually inspect the tires again. On a trim that could use either 19-inch or 20-inch fitments, this early review is especially helpful because it confirms that the chosen tire matches the actual wheel package on the car.
How often should tires on a 2018 Jaguar XF be inspected?
Tires on a 2018 Jaguar XF should be inspected regularly, not just when tread looks low. Pressure, visible wear, cuts, punctures, bulges, and uneven shoulder wear are all worth checking, especially on the lower-profile 19-inch and 20-inch fitments where road impacts and alignment issues can show up more quickly.
A quick visual check before longer drives is a sensible habit, and periodic closer inspections help catch problems before they become expensive or unsafe. Cars that sit for extended periods still need attention because age, air loss, and sidewall condition matter even when mileage stays low. Looking at the tires often is one of the easiest ways to protect ride quality and wheel condition.
