In 2009, Jaguar balanced traditional British luxury with a more modern performance edge, offering everything from long-wheelbase XJ sedans to the newer XF and the sleek XK grand touring line. That spread of models means tire sizing is not uniform across the range, even though the overall character remains distinctly Jaguar. Across seven 2009 Jaguar models, eight radial sizes appear, with some shared between multiple sedans or coupes and others reserved for specific performance-oriented applications. The first step is to confirm whether you have an XJ-series sedan, an XF, or an XK-family car, then verify the exact front and rear size before choosing a tire.
Which Tire Size Is Right for Your 2009 Jaguar
Eight tire sizes are used across 2009 Jaguar vehicles, and they vary by model rather than carrying across the entire range. The real decision starts with identifying the correct model and wheel diameter first, since these sizes span 18-, 19-, and 20-inch fitments and some Jaguar models use staggered front-and-rear combinations. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2009|Fit(s): Super V8, XF, XJR, XK, XKR|Construction: Radial|Rim: 20 in
A 255/35R20 is a radial tire with a 255-millimeter section width, a 35-series aspect ratio, and a 20-inch rim diameter. This size is available from BFGoodrich and Nitto in Blackwall form, and speed ratings vary by product with W-rated options to 168 mph and Y-rated options to 186 mph and above. On 2009 Jaguar applications, this is not a universal size across the whole range, but it is shared by several higher-spec or sport-oriented models that run 20-inch wheels. It suits owners who have confirmed a 20-inch fitment and want a modern radial in an appropriate low-profile performance size.
Year(s): 2009|Fit(s): Super V8, Vanden Plas, XJ8, XJR|Construction: Radial|Rim: 19 in
A 255/40R19 is a radial tire with a 255-millimeter section width, a 40-series aspect ratio, and a 19-inch rim diameter. BFGoodrich covers this size in Blackwall form, and speed ratings vary by product with W-rated choices to 168 mph and Y-rated choices to 186 mph and above. This size is specific to 2009 Jaguar XJ-based sedans and the Super V8 rather than the full model range, so it is best matched after confirming the exact wheel package on the car. It is a straightforward choice for owners of 19-inch luxury-sport sedan applications who want to stay with a modern radial layout.
Year(s): 2009|Fit(s): Vanden Plas, XJ8|Construction: Radial|Rim: 18 in
A 235/50R18 is a radial tire with a 235-millimeter section width, a 50-series aspect ratio, and an 18-inch rim diameter. This size is available from BFGoodrich and Nitto in Blackwall styling, with W-rated products reaching 168 mph. It is specific to the 2009 Jaguar Vanden Plas and XJ8, where the taller sidewall and 18-inch wheel package fit the more comfort-oriented sedan side of the lineup. Owners choosing for those models should confirm the car remains on its 18-inch wheels rather than a later wheel swap.
Year(s): 2009|Fit(s): XF, XK, XKR|Construction: Radial|Rim: 19 in
A 245/40R19 is a radial tire with a 245-millimeter section width, a 40-series aspect ratio, and a 19-inch rim diameter. BFGoodrich offers this size in Blackwall form, and speed ratings vary by product with W-rated options to 168 mph and Y-rated options to 186 mph and above. This size is shared by the 2009 Jaguar XF, XK, and XKR rather than by every Jaguar model for the year, so it should be matched to the correct front or all-around application on those cars. It is well suited to owners keeping a 19-inch setup with a modern performance radial profile.
Year(s): 2009|Fit(s): XF, XK|Construction: Radial|Rim: 18 in
A 245/45R18 is a radial tire with a 245-millimeter section width, a 45-series aspect ratio, and an 18-inch rim diameter. BFGoodrich and Nitto offer it in Blackwall form, with W-rated choices to 168 mph and Y-rated choices to 186 mph and above. This size is specific to certain 2009 Jaguar XF and XK applications and is not shared by the whole Jaguar lineup. It makes sense for owners who have verified an 18-inch wheel package and want a modern radial with a bit more sidewall than the lower-profile 19- and 20-inch choices.
Year(s): 2009|Fit(s): XF, XK, XKR|Construction: Radial|Rim: 20 in
A 285/30R20 is a radial tire with a 285-millimeter section width, a 30-series aspect ratio, and a 20-inch rim diameter. Nitto and Pro-Trac offer this size, with sidewall choices including Blackwall, RWL, and Redline, and the available W rating carries a 168 mph ceiling where shown. This size is specific to 2009 Jaguar XF, XK, and XKR applications and commonly appears as part of a wider rear fitment rather than a universal year-and-make size. It is a strong match for owners preserving the visual stance of a staggered 20-inch setup while choosing among different sidewall looks.
Year(s): 2009|Fit(s): XK|Construction: Radial|Rim: 18 in
A 255/45R18 is a radial tire with a 255-millimeter section width, a 45-series aspect ratio, and an 18-inch rim diameter. BFGoodrich, Nitto, and Pro-Trac offer it, with sidewall styles including Blackwall and RWL, and W-rated products in the size reach 168 mph. This is the most model-specific size in the 2009 Jaguar range, applying only to the XK rather than to the sedan line or the supercharged variants. It is best for XK owners who have confirmed the factory-style 18-inch fitment and want to keep the car's grand touring balance intact.
Year(s): 2009|Fit(s): XK, XKR|Construction: Radial|Rim: 19 in
A 275/35R19 is a radial tire with a 275-millimeter section width, a 35-series aspect ratio, and a 19-inch rim diameter. BFGoodrich and Nitto offer this size in Blackwall form, with W-rated choices to 168 mph and Y-rated choices to 186 mph and above. This size is specific to 2009 Jaguar XK and XKR applications and is typically associated with the wider end of the XK-family fitment range. It suits owners maintaining a 19-inch performance-oriented setup after verifying whether their car uses this size at one axle or as part of a staggered combination.
Seven 2009 Jaguar models are covered here, spanning traditional XJ sedans, the newer XF sport sedan, and the XK grand touring coupe and convertible family. Tire size varies by model, and in several cases by wheel package or front-to-rear application, so identifying the exact model matters before choosing a size. Select a model below to narrow the fitment history and see the tires that apply to that Jaguar.
2009 Jaguar Super V8
The 2009 Jaguar Super V8 sits at the top of the XJ sedan range, blending formal luxury with supercharged performance in the final years of the classic aluminum-bodied X350 generation. Its tires mount on either 19-inch or 20-inch rims depending on the fitment, making wheel confirmation especially important on cars that may have changed hands through several owners.
The 2009 Jaguar Vanden Plas emphasizes long-wheelbase comfort and traditional Jaguar luxury, with a quieter and more formal mission than the sportier XJ variants. Its tires mount on 18-inch or 19-inch rims, so the choice comes down to confirming which wheel package is on the car rather than sorting through a wide mix of unrelated sizes.
Associated Tire Sizes:
235/50R18 — radial, comfort-oriented sedan fitment
The 2009 Jaguar XF marked a major stylistic shift for Jaguar, introducing a more contemporary sport-sedan look and a distinctly newer cabin and chassis character than the outgoing S-Type. Its fitments span 18-, 19-, and 20-inch rims, and some applications use wider rear sizing, so the exact wheel and axle position should be checked before selecting tires.
The 2009 Jaguar XJ8 carries the restrained, classic XJ silhouette while using Jaguar's lightweight aluminum sedan architecture for a refined but responsive driving feel. It uses either 18-inch or 19-inch rim diameters, so owners should confirm the actual wheels on the car before moving to a tire choice.
The 2009 Jaguar XJR is the supercharged, high-performance XJ, pairing the traditional Jaguar sedan shape with more serious straight-line pace and sharper intent. Its tires mount on 19-inch or 20-inch rims, which means buyers should verify whether the car remains on its original wheel package or has been changed to another factory-style setup.
The 2009 Jaguar XK is a true grand touring Jaguar, with aluminum construction, long-hood proportions, and a broad spread of wheel and tire combinations depending on trim and chassis setup. Its fitments cover 18-, 19-, and 20-inch rims, including wider rear sizes on some applications, so this is one model where exact tire size matters as much as the model name itself.
Associated Tire Sizes:
245/40R19 — radial, front or all-around GT fitment
The 2009 Jaguar XKR takes the XK platform and adds supercharged performance, giving the car a stronger emphasis on high-speed touring and a more aggressive stance. Its tires use 19-inch and 20-inch rim diameters, often with wider rear sizing, so matching front and rear sizes correctly is essential on these cars.
Thirty-seven products are available across eight tire sizes for 2009 Jaguar vehicles. Size coverage includes 255/35R20 from BFGoodrich and Nitto in radial Blackwall form, 255/40R19 from BFGoodrich radial Blackwalls, 235/50R18 from BFGoodrich and Nitto radial Blackwalls, 245/40R19 from BFGoodrich radial Blackwalls, 245/45R18 from BFGoodrich and Nitto radial Blackwalls, 285/30R20 from Nitto and Pro-Trac radial Blackwall, RWL, and Redline styles, 255/45R18 from BFGoodrich, Nitto, and Pro-Trac radial Blackwall and RWL styles, and 275/35R19 from BFGoodrich and Nitto radial Blackwalls. Confirm the exact size first, since speed ratings can vary between products in the same size.
These answers focus on how 2009 Jaguar tire sizing changes across the XJ, XF, and XK families, what the metric size codes mean, and how sidewall style, speed rating, and setup details affect a collector-driven modern Jaguar.
Size Basics & Fitment
What tire sizes fit 2009 Jaguar vehicles?
2009 Jaguar vehicles use eight tire sizes across seven model lines: 255/35R20, 255/40R19, 235/50R18, 245/40R19, 245/45R18, 285/30R20, 255/45R18, and 275/35R19. The Vanden Plas and XJ8 use 235/50R18 or 255/40R19, the Super V8 uses 255/40R19 or 255/35R20, the XJR uses 255/40R19 or 255/35R20, the XF uses 245/45R18, 245/40R19, 255/35R20, and 285/30R20, the XK uses six sizes across 18-, 19-, and 20-inch fitments, and the XKR uses 245/40R19, 255/35R20, 275/35R19, and 285/30R20.
That means year and make alone are not enough for a correct choice on a 2009 Jaguar. Start by identifying the exact model, then confirm whether the car uses 18-, 19-, or 20-inch wheels and whether it has a staggered setup with different front and rear sizes. Rim width ranges also vary by size, from 6.5-8.5 inches on 235/50R18 up to 9-11 inches on 275/35R19, so wheel measurement matters before a final tire decision.
What does 255/35R20 mean on a 2009 Jaguar tire?
On a 2009 Jaguar, 255/35R20 is a metric radial size. The 255 is the nominal section width in millimeters, 35 is the aspect ratio, the R means radial construction, and 20 is the wheel diameter in inches. On 2009 Jaguar applications, that size appears on the Super V8, XF, XJR, XK, and XKR, all of which use it with a 20-inch wheel.
That code matters because it tells you more than just width. The short 35-series sidewall gives the car a distinctly low-profile appearance and limits the tire to a 20-inch rim, so it cannot substitute directly for an 18- or 19-inch fitment. When a 2009 Jaguar has been modified with later wheels, checking the actual tire code on the car is often faster and more reliable than assuming the original wheel package stayed in place.
Do all 2009 Jaguar models use the same tire size?
No, 2009 Jaguar models do not share one universal tire size. The XJ-family sedans center around 18- and 19-inch sizes such as 235/50R18 and 255/40R19, while the XF spans 18 through 20 inches, and the XK/XKR line reaches from 18-inch grand touring fitments to wider 19- and 20-inch performance sizes including 275/35R19 and 285/30R20. Several sizes are shared across multiple models, but none apply to every 2009 Jaguar.
The practical takeaway is simple: identify the model before focusing on the tire. On a 2009 Jaguar XK or XKR, it is also wise to confirm whether the car uses the same size at both ends or a staggered arrangement. That extra step prevents ordering a pair of front-size tires for a rear application or choosing an 18-inch size for a car that actually carries 19- or 20-inch wheels.
Buying the Right Tire
What sidewall styles are available for 2009 Jaguar tires?
Most 2009 Jaguar tire sizes here are offered in Blackwall form, which suits the original modern luxury and performance character of the XF, XJ, XK, and XKR ranges. Two sizes add visual alternatives: 285/30R20 is available in Blackwall, RWL, and Redline, while 255/45R18 is available in Blackwall and RWL. Those style choices appear mainly in sizes associated with XK-family and broader performance-oriented fitments rather than the more formal sedan sizes.
For a 2009 Jaguar restoration or preservation-minded street car, Blackwall is usually the safest visual direction because it matches the understated premium look Jaguar favored in this era. RWL or Redline can create a custom appearance, but they move the car away from stock presentation. Owners who attend marque events or want the car to read as factory-correct should think about sidewall style as part of the overall look, not just as a tire specification.
What brands make tires for 2009 Jaguar vehicles?
2009 Jaguar sizes are covered by BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears across nearly the full range, including 255/35R20, 255/40R19, 235/50R18, 245/40R19, 245/45R18, 255/45R18, and 275/35R19. Nitto is present in 255/35R20, 235/50R18, 245/45R18, 285/30R20, 255/45R18, and 275/35R19, while Pro-Trac is offered in 285/30R20 and 255/45R18.
That brand spread gives 2009 Jaguar owners different ways to approach the same basic fitment. Some sizes, especially the common sedan and front-axle performance sizes, stay focused on Blackwall sport radials, while a few rear or XK-related sizes open the door to alternate sidewall styling. The right brand choice starts with the correct size, then narrows by the look you want and the speed rating appropriate to your car's intended road use.
What is the difference between BFGoodrich g-Force Comp 2 A/S and BFGoodrich g-Force Phenom T/A for the 2009 Jaguar?
For several 2009 Jaguar sizes, both BFGoodrich g-Force Comp 2 A/S and BFGoodrich g-Force Phenom T/A are available in the same basic dimensions but with different speed ratings and, in some cases, published load details. In 255/35R20, the Comp 2 A/S appears with a 97W rating while the Phenom T/A carries a 97Y rating and a 1,609-pound load figure at 50 psi. In 255/40R19, the Comp 2 A/S appears in W- and Y-rated forms, while the Phenom T/A is also available with a 100Y rating and a 1,764-pound load figure at 50 psi.
That means the difference is not simply branding. On a 2009 Jaguar, especially a faster XK, XKR, Super V8, or XJR application, paying attention to the exact speed symbol can matter as much as the model name on the sidewall. If you are comparing two BFGoodrich options in the same size, check the full sidewall code rather than assuming every tire in that family carries the same speed ceiling or load specification.
Fitting & Setup
What rim width do 2009 Jaguar tires require?
Rim width requirements for 2009 Jaguar tires vary by size. The 235/50R18 fits 6.5-8.5-inch rims, 245/45R18 fits 7.5-9.0-inch rims, 255/45R18 fits 8.0-9.5-inch rims, 245/40R19 fits 8.0-9.5-inch rims, 255/40R19 fits 8.5-10.0-inch rims, 255/35R20 fits 8.5-10.0-inch rims, and 275/35R19 fits 9.0-11.0-inch rims. Those ranges show how quickly wheel needs change as the tire gets wider and lower in profile.
The main implication is that two tires sharing a similar outside stance may still want different wheels. On a 2009 Jaguar with replacement rims, measure the actual wheel width before choosing a tire, especially on XK and XKR models that often run wider rear tires. Staying within the published width range helps preserve sidewall shape, steering response, and clearance, all of which matter on a heavier, more performance-oriented luxury car.
Do 2009 Jaguar tires require inner tubes?
The available 2009 Jaguar products are modern radial tires and the markings do not indicate tube-type construction. Some carry explicit tubeless notation such as XLTL, while others use standard modern metric radial sidewall markings without a tube-type designation. In practical terms, these are tubeless-style fitments rather than vintage tube-type applications, which is exactly what you would expect on a 2009 Jaguar with contemporary one-piece alloy wheels.
Even so, wheel condition still matters. If a 2009 Jaguar has corrosion around the bead seat, bent rims, or damaged valve stems, a tubeless tire can still lose air or seat poorly. The right setup step is to inspect the wheel, replace worn stems, and make sure the rim surface is clean and true before mounting. Tube installation is not the normal solution here; correcting the wheel or hardware condition usually is.
Can the original 2009 Jaguar wheels be used with all tire sizes?
Original 2009 Jaguar wheels can only be used with the tire sizes that match their rim diameter, and this year spans 18-, 19-, and 20-inch fitments. An 18-inch Jaguar wheel accepts only 18-inch tire sizes such as 235/50R18, 245/45R18, or 255/45R18, while a 19-inch wheel takes 245/40R19, 255/40R19, or 275/35R19, and a 20-inch wheel takes 255/35R20 or 285/30R20. Diameter must match exactly.
Width still needs to be checked after diameter. A wheel that works for 245/40R19 may not be the right width for 275/35R19, even though both mount on 19-inch rims. That is especially important on 2009 Jaguar XK and XKR models, where front and rear wheel widths can differ. Confirming both diameter and wheel width protects against mounting a tire that physically fits the rim bead but does not sit correctly on the wheel.
Maintenance, Storage & Longevity
How should I store a 2009 Jaguar when the tires are fitted?
A stored 2009 Jaguar should be kept out of direct sunlight, away from electric motors and ozone sources, and on a dry surface with stable temperature if possible. Even modern radials can develop flat-spotting when the car sits for long periods, especially on heavier luxury and grand touring models like the XJ and XK family. Maintaining proper inflation before storage helps the tire keep its shape.
For a car that rests through part of the year, move it periodically or place it on stands if the storage plan is truly long term. If you leave the car on its tires, rolling it a short distance every few weeks changes the contact patch and reduces prolonged stress in one area. A breathable cover and a clean storage environment do more for tire life than frequent cosmetic treatments on the sidewalls.
How long do tires on a 2009 Jaguar typically last?
On a collector-driven 2009 Jaguar, tire age usually matters more than tread wear. A sensible rule is to evaluate tires closely once they reach five to seven years of age and to treat about ten years as the point where replacement deserves serious consideration, even if the tread still looks usable. The DOT date code on the sidewall tells you when each tire was built.
That timeline matters because many 2009 Jaguars cover relatively low annual mileage. A tire can look healthy at a glance yet still harden with age, lose wet-weather confidence, or develop subtle cracking that only appears under close inspection. Matching tire age across the axle is also wise, since one recently replaced tire beside one much older tire can give the car an uneven feel, especially on a sport-oriented Jaguar chassis.
How often should tires on a 2009 Jaguar be inspected?
Tires on a 2009 Jaguar deserve a quick inspection before every drive and a more careful inspection before any longer outing. Look for sidewall cracking, tread damage, punctures, bulges, uneven wear, and signs of pressure loss. On cars with staggered sizes, inspect all four tires individually rather than assuming front and rear are wearing at the same rate.
That routine is especially important on a Jaguar that spends time parked between drives. Low-profile 19- and 20-inch tires can hide impact damage from potholes, and underinflation may not always be obvious until the car feels unsettled on the road. A few minutes with a pressure gauge and a flashlight is usually enough to catch small problems early, before they become expensive wheel damage or a spoiled touring weekend.
Safety & Road Use
Are 2009 Jaguar tires safe for highway driving?
Yes, the available 2009 Jaguar tires are modern radials and many carry substantial speed capability. W-rated products are approved to 168 mph, while Y-rated products are approved to 186 mph and above, depending on the exact size and tire chosen. That is well beyond ordinary U.S. highway speeds, and in normal use the car's alignment, suspension condition, brake health, and tire age will usually matter more than the raw speed symbol alone.
The important point is to match the tire to the car's intended use and to keep the whole vehicle in proper condition. A 2009 Jaguar XKR or Super V8 can quickly expose weak shocks, poor balance, or aging bushings that a slower car might mask. Highway safety comes from the full package: the correct size, the right speed-rated tire for the application, proper inflation, and a chassis that is ready for sustained road use.
What inflation pressure should I use for 2009 Jaguar tires?
Inflation pressure on a 2009 Jaguar should follow the vehicle placard or owner's manual first, because Jaguar set those figures around the car's weight distribution and intended handling balance. Tire pressure figures tied to load ratings vary by size and product; for example, 235/50R18 appears with load figures up to 1,819 pounds at 50 psi, 255/45R18 reaches 1,929 pounds at 50 psi, 255/35R20 shows 1,609 pounds at 50 psi in one application, and several 19-inch sizes appear with 1,653- or 1,764-pound figures at 50 psi.
Those numbers are not a blanket recommendation to run every tire at 50 psi. They show the pressure associated with each tire's rated maximum load, not necessarily the correct operating pressure for a 2009 Jaguar on the street. Use Jaguar's vehicle-specific recommendation as your baseline, then confirm that the tire you choose supports the needed load at that pressure range. If the car uses a staggered setup, check whether front and rear pressures differ.
What should I check before taking a 2009 Jaguar on a longer drive?
Before a longer trip in a 2009 Jaguar, inspect each tire for cracking, cuts, bulges, punctures, and uneven wear, then verify cold pressure with an accurate gauge. Confirm that the spare, if present, is usable and properly inflated, and look over the valve stems for age or damage. On XK, XKR, and some XF applications, double-check that the front and rear tire sizes are where they belong if the car uses a staggered arrangement.
A tire check should be part of a broader pre-drive routine on any touring-oriented Jaguar. Wheel balance issues, worn suspension pieces, or old alignments can become much more noticeable at highway speed, even when the tires themselves are in good condition. If the car has sat for a while, take a short test drive first to feel for vibration or pulling before committing to a full day on the road.
