The 1951 Jaguar XK sits at the heart of Jaguar’s early postwar sports-car story, blending long-hood British style with the kind of road performance that made the XK name famous. For many owners, the appeal is not just how the car looks at rest, but how faithfully it presents on the road. Tire choice matters because this Jaguar XK can be found with either a 600-16 bias-ply fitment or a 175R16 radial on 16-inch rims. That opens the door to period-style bias-ply options as well as a more modern radial format. The right choice depends on whether the priority is restoration character, road manners, or a careful balance of both.
Which Tire Size Is Right for The 1951 Jaguar XK
The 1951 Jaguar XK uses two primary tire sizes, both on 16-inch rims: 600-16 in bias-ply construction and 175R16 in radial construction. Since the XK 120 is associated with both sizes, the key decision is not just wheel diameter but which tire construction and visual character best match the car’s current setup, intended road use, and restoration direction.
175R16 is a Euro-metric radial size, with 175 indicating the nominal section width in millimeters, R identifying radial construction, and 16 showing the wheel diameter in inches. On a 1951 Jaguar XK, this size represents the more modern construction choice while still using the correct 16-inch rim diameter. Its appeal is less about vintage numeric sizing and more about giving the car a radial-format option that suits regular road use. This is the size to evaluate if the car already runs radial-compatible wheels and the goal is a traditional-looking fitment with radial construction.
600-16 is a numeric bias-ply size, with the leading number representing an approximately 6.00-inch nominal section width and the final number indicating a 16-inch rim. For a 1951 Jaguar XK, this is the more traditional fitment style and carries the visual character many restoration-minded owners want from an early-1950s sports car. Available choices include brands such as BFGoodrich, Coker Classic, Avon, Firestone, Goodyear, Lester, Excelsior, Ford Script, STA, and Camac, with blackwall, wide whitewall, and double-whitewall treatments across several tire series. This size makes the most sense when period-style appearance and bias-ply presentation are central to the car’s overall look.
Fitment is straightforward here because the covered 1951 Jaguar XK sub-model shares the same two primary tire-size paths. The real choice is deciding whether the XK 120 should remain with a traditional 600-16 bias-ply presentation or be evaluated around the 175R16 radial format.

1951 Jaguar XK 120
The 1951 Jaguar XK 120 is associated with both 600-16 bias-ply and 175R16 radial sizing on a 16-inch rim. That means tire selection centers on construction, appearance, and wheel suitability rather than sorting through multiple trim-specific diameters.
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.

Tire Size & Fitment
What tire size fits a 1951 Jaguar XK?
A 1951 Jaguar XK uses two primary tire sizes: 600-16 in bias-ply construction and 175R16 in radial construction. Both sizes are associated with the XK 120 and both use a 16-inch rim, so the fitment question is tied more to construction type and wheel setup than to a change in wheel diameter.
That means the first step is confirming how the car is currently equipped and what kind of result is wanted from the new tires. A restoration-oriented car may lean toward the 600-16 bias-ply size, while a road-driven XK may be evaluated around 175R16, provided the wheels and clearances are appropriate for that construction.
What size rim does a 1951 Jaguar XK use?
The 1951 Jaguar XK uses a 16-inch rim with both of its associated tire sizes. The bias-ply 600-16 and the radial 175R16 both share that same rim diameter, which keeps wheel diameter simple even though the car can be equipped with two different tire constructions.
Rim diameter is only one part of the fitment picture, though. Width still matters, especially when comparing individual tires, and any Jaguar that has been altered over the years should have its actual wheel dimensions checked before a new set is chosen. Construction changes can also affect the overall fitment conversation.
Does the 1951 Jaguar XK 120 use the same tire size?
The 1951 Jaguar XK 120 is associated with the same two tire-size paths used on this page: 600-16 bias-ply and 175R16 radial. In other words, the sub-model does not introduce a separate rim diameter or an entirely different size family that would change the basic fitment decision.
That keeps the choice focused on how the car is being used and presented. An owner choosing tires for an XK 120 should spend more time confirming wheel compatibility, desired appearance, and whether bias-ply or radial construction better suits the car than worrying about a unique sub-model-only tire size.
Choosing the Right Tire
What should I consider when choosing a 600-16 tire for a 1951 Jaguar XK?
Choosing a 600-16 tire for a 1951 Jaguar XK starts with confirming that the car is staying with a bias-ply setup and 16-inch wheels suited to that size. From there, the meaningful differences are brand, tire series, sidewall style, rim-width specification, load figure where stated, and whether the goal is a sportier blackwall or a more formal whitewall look.
Some 600-16 products are clearly restoration-oriented passenger-car tires, while others in the same size are military or truck-style patterns that create a very different appearance. Matching the tread style and sidewall treatment to the Jaguar’s presentation matters just as much as selecting the right numeric size on the sidewall.
What sidewall styles are available for 1951 Jaguar XK tires?
In 600-16, the 1951 Jaguar XK has access to blackwall, wide whitewall, and double-whitewall sidewall treatments. Those options create noticeably different visual results even when the size stays the same, so sidewall style is one of the most important appearance decisions for an early-1950s sports car with exposed, highly visible tire sidewalls.
A blackwall usually delivers the most restrained and sporting presentation, while whitewall styles shift the car toward a dressier period look. Since sidewall treatment changes the overall character of the XK so much, it helps to decide early whether the car is being finished as a lean road car or a more formal restoration-style example.
What brands offer tires for the 1951 Jaguar XK?
The 600-16 fitment for a 1951 Jaguar XK is available from BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those brands appear across several bias-ply tire series, giving the buyer a broad mix of traditional passenger-car styling, whitewall treatments, and more specialized tread patterns in the same nominal size.
Brand choice should be considered alongside the specific tire series and its visual character rather than treated as a ranking exercise. On a collector Jaguar, the difference between a classic blackwall road tire and a military-style pattern can be far more important than the name on the sidewall when the goal is a cohesive finished look.
Restoration & Appearance
Which tire should I choose for a period-style 1951 Jaguar XK?
For a period-style 1951 Jaguar XK, the 600-16 bias-ply size is the strongest starting point because it preserves the vintage numeric sizing and traditional construction associated with the car’s era. Within that size, the visual result can still vary quite a bit depending on whether the tire is a blackwall, wide whitewall, or double-whitewall design.
The right restoration-oriented choice depends on how the car is being interpreted rather than on one universal answer. Owners pursuing exact originality should compare tire appearance against marque-club guidance, historical photography, and vehicle-specific documentation, while those aiming for a faithful road presentation can choose the sidewall style that best matches the car’s finished character.
How does tire construction affect the appearance of a restored 1951 Jaguar XK?
Tire construction changes the visual impression of a restored 1951 Jaguar XK more than many buyers expect. A 600-16 bias-ply gives the car a distinctly vintage presentation tied to early-1950s sports-car proportions, while a 175R16 radial introduces a later sizing convention and a more modern construction even though it still fits a 16-inch rim.
That difference matters most on a car as visually clean as the XK, where the wheel and tire package is always in view. Buyers restoring for show, preservation, or a strongly period-style look usually weigh construction as part of the car’s overall stance, not just as a driving decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1951 Jaguar XK?
Yes, modifications can affect tire fitment on a 1951 Jaguar XK even when the tire size itself appears correct. Aftermarket wheels, changes in wheel width, suspension alterations, brake conversions, or bodywork differences can all change the space available around a 600-16 or 175R16 tire and alter how the tire sits on the car.
A Jaguar that has been changed from original specification should have its actual wheel dimensions and clearances checked before new tires are selected. Steering movement, fender space, and suspension travel deserve close attention, especially when changing between bias-ply and radial construction or moving from an older stored set to a fresh replacement.
What should I inspect before driving a 1951 Jaguar XK on new tires?
Before driving a 1951 Jaguar XK on new tires, inspect wheel condition, valve hardware, visible clearance at the fenders and suspension, and the general state of the steering and suspension components. Tire pressure should be set correctly for the chosen tire, and the car should be checked for any signs of rubbing, uneven stance, or interference once the new tires are mounted.
A short, careful road test is the best next step. Listen for contact during turns, watch for vibration, and recheck air pressure after the tires have settled in. On a collector Jaguar that may sit for long periods, it is also wise to confirm there is no age-related cracking or air loss elsewhere in the wheel-and-tire assembly.
How should tires on a collector 1951 Jaguar XK be maintained?
Tires on a collector 1951 Jaguar XK should be inspected regularly for cracking, flat spotting, bulges, cuts, irregular tread wear, and slow air loss. Because many vintage Jaguars spend long stretches in storage, condition can become just as important as mileage, especially when the car is only driven occasionally and tire aging is easy to overlook.
Proper inflation, clean storage conditions, and protection from prolonged sunlight, heat, moisture, and ozone sources all help preserve tire life. It also helps to examine the tires before every meaningful drive rather than waiting for an annual check, since a lightly used collector car can develop tire issues long before the tread looks worn.
