The 1991 Jaguar XJ6 sits firmly in the tradition of Jaguar luxury sedans that balanced long-distance comfort with a distinctly European road feel. Buyers are usually preserving one of these cars for refined weekend use, touring, or an authentic late-classic British presentation rather than treating it like a generic used sedan. For this exact model, the primary tire fitment is 205/70R15 in radial construction on a 15-inch rim. That leaves room to choose among blackwall, narrow whitewall, wide whitewall, and even a bias-look radial presentation across several well-known tire series. The right selection depends on whether the priority is factory-inspired appearance, touring use, or maintaining the car's intended stance and fitment.
Which Tire Size Is Right for The 1991 Jaguar XJ6
The 1991 Jaguar XJ6 uses one primary tire size: 205/70R15, a radial fitted to a 15-inch rim. Both the Base and Sovereign share that same fitment, so the main decision is not which size fits, but which version of that size best matches the car's appearance, driving use, and wheel specifications.
205/70R15 is a metric radial size in which 205 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On the 1991 Jaguar XJ6, that means a modern radial fitment rather than an earlier bias-ply sizing system. Within this size, choices include blackwall, narrow whitewall, wide whitewall, and multiple tire series from brands such as Michelin, Avon, Dunlop, Maxxis, American Classic, Coker Classic, Tornel, and Travelstar. The practical choice comes down to preserving a traditional luxury-sedan look, matching wheel width, and selecting the sidewall treatment that best suits the car.
Tire fitment is straightforward across the covered 1991 Jaguar XJ6 sub-models because both use the same 205/70R15 radial size. Checking the exact sub-model still helps confirm that the wheel and tire setup has not been changed over time.

1991 Jaguar XJ6 Base
The 1991 Jaguar XJ6 Base uses the shared 205/70R15 radial fitment on a 15-inch rim. That makes tire selection more about choosing the right sidewall style, tire series, and wheel-width compatibility than sorting through multiple primary sizes.
The 1991 Jaguar XJ6 Sovereign also uses the shared 205/70R15 radial size on a 15-inch rim. Selection usually centers on whether the car should wear a blackwall sport-touring look or a whitewall treatment that better matches a restoration-oriented luxury presentation.
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.

These 1991 Jaguar XJ6 tire FAQs focus on the 205/70R15 fitment, 15-inch wheel compatibility, product and sidewall choices, restoration-minded appearance, and the checks worth making before road use on a collector-era Jaguar.
Tire Size & Fitment
What tire size fits a 1991 Jaguar XJ6?
The 1991 Jaguar XJ6 uses a 205/70R15 radial tire. That is the primary fitment for both the Base and Sovereign versions, so the size itself remains consistent across the covered sub-models.
That consistency simplifies the search, but the right choice still depends on the actual wheel and the look you want. A 205/70R15 can be found in blackwall, narrow whitewall, wide whitewall, and bias-look radial form, so it is worth confirming the wheel diameter, wheel width, and overall appearance goal before settling on a specific tire.
What size rim does a 1991 Jaguar XJ6 use?
The 1991 Jaguar XJ6 uses a 15-inch rim with its 205/70R15 tire size. That 15-inch diameter is the wheel dimension that matters first, since the tire must match the rim diameter exactly.
Wheel width also matters when comparing specific tires in this size. Some 205/70R15 options are suited to widths such as 5.00 to 7.00 inches or 5.50 to 7.50 inches, and one is shown with a 6J rim fitment, so checking the wheel before purchase helps avoid appearance or compatibility issues.
Do all 1991 Jaguar XJ6 sub-models use the same tire size?
Yes. Both the 1991 Jaguar XJ6 Base and the 1991 Jaguar XJ6 Sovereign use the same 205/70R15 radial tire size. There is no split in primary size between those two covered sub-models.
Even so, a long-owned Jaguar may no longer be wearing its original wheel setup. A previous owner could have changed wheels, suspension height, or tire style, so the safest approach is to confirm the actual 15-inch wheel diameter and width on the car before choosing among the available blackwall or whitewall 205/70R15 options.
Choosing the Right Tire
What should I consider when choosing a 205/70R15 tire for a 1991 Jaguar XJ6?
Start with the correct 205/70R15 size and confirm that the tire suits the car's 15-inch wheel. From there, the meaningful differences are sidewall style, construction presentation, tire series, and whether the wheel width matches the specifications of the tire you are considering.
A blackwall tire tends to suit a more understated or sporting presentation, while narrow and wide whitewalls lean more toward a traditional luxury-sedan appearance. Comparing load figures, wheel-width ranges, and the overall visual style helps narrow the choice without treating every 205/70R15 as identical.
What sidewall styles are available for 1991 Jaguar XJ6 tires?
The 1991 Jaguar XJ6 has 205/70R15 options in blackwall, narrow whitewall, and wide whitewall styles. That gives the car a broad range of visual directions, from a more restrained European look to a more traditional restoration-oriented luxury appearance.
Choosing among them depends less on fitment than on presentation. Blackwalls are common in performance-leaning or touring-oriented tire lines, while narrow and wider whitewalls can better complement chrome trim and the formal styling of the XJ6, provided the wheel and tire specifications still match the car properly.
What brands offer tires for the 1991 Jaguar XJ6?
205/70R15 tires for the 1991 Jaguar XJ6 are available from Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. Those brands cover a mix of traditional whitewall radials, blackwall touring and sport-oriented lines, and a bias-look radial presentation.
Brand alone should not make the decision. It is more useful to compare the tire series, sidewall style, construction description, wheel-width suitability, and any stated load figures, then match those details to how the Jaguar will be used and how authentic or formal you want the finished look to appear.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Jaguar XJ6?
A period-style 1991 Jaguar XJ6 usually starts with the correct 205/70R15 size and then narrows the choice by sidewall treatment and tire character. Wide whitewall, narrow whitewall, blackwall, and bias-look radial options all exist in this size, so the decision is more about presentation than basic fitment.
For a more formal luxury-sedan appearance, whitewall styles often make the strongest visual statement. If exact originality matters, it is wise to compare the car against marque references, historical photos, or restoration documentation, since a tire that looks right in size and era may still differ from the car's original showroom presentation.
How does tire construction affect the appearance of a restored 1991 Jaguar XJ6?
On a restored 1991 Jaguar XJ6, construction affects both the sidewall profile and the overall visual impression of the car. Most available 205/70R15 choices are standard radials, while one option uses a bias-look radial construction that can give the tire a more traditional presentation.
That distinction matters if the goal is a restoration-oriented look without moving away from a radial size. The best approach is to compare the sidewall style and series character first, then make sure the selected tire still suits the actual wheel width and the way the Jaguar will be driven.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Jaguar XJ6?
Yes. A 1991 Jaguar XJ6 may use the standard 205/70R15 size, but aftermarket wheels, suspension changes, altered ride height, or body modifications can all change how much room the tire has inside the wheel opening and around steering components.
That is why the wheel on the car should be checked rather than assuming every XJ6 still carries its original setup. Confirm the 15-inch rim diameter, measure wheel width, and inspect clearance at full steering lock and normal ride height before choosing among the available 205/70R15 tires.
What should I inspect before driving a 1991 Jaguar XJ6 on new tires?
Before driving a 1991 Jaguar XJ6 on new tires, inspect the wheels for proper diameter and condition, make sure the tires are inflated correctly, and verify that there is no rubbing at the fenders or steering components. It is also smart to check the valve stems and overall wheel mounting condition.
A collector-era sedan can reveal old suspension or alignment issues once fresh tires are installed. Looking over bushings, shocks, steering response, and any uneven wear patterns helps protect the new tires and makes sure the car delivers the composed road manners the XJ6 is known for.
How should 205/70R15 tires on a collector 1991 Jaguar XJ6 be maintained?
205/70R15 tires on a collector 1991 Jaguar XJ6 should be checked regularly for air pressure, sidewall cracking, cuts, bulges, uneven tread wear, and signs of slow air loss. Cars that are driven infrequently need these inspections just as much as cars that cover a lot of miles.
Storage conditions matter too. Keeping the Jaguar away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires over time, and moving the car periodically can help avoid long-term flat spotting. Regular visual checks are especially important on low-use collector vehicles.
