The 1955 Jaguar XK sits in a particularly interesting place in postwar sports-car history, bridging the graceful XK120 and the more developed XK140 while pointing toward the later XK150. Buyers looking at one today are often balancing touring use, restoration priorities, and the distinctive road manners of a mid-century British performance car. Tire fitment centers on two 16-inch choices: a 600-16 bias-ply size and a 175R16 radial. That gives the XK owner a meaningful decision between traditional bias-ply presentation and a radial alternative, along with available differences in brand, tire series, and sidewall style. The right choice starts with how the car is driven and how authentic or updated the finished look should be.
Which Tire Size Is Right for The 1955 Jaguar XK
The 1955 Jaguar XK uses two primary tire sizes, both on 16-inch rims: 600-16 in bias-ply construction and 175R16 in radial construction. Because both XK 120 & 140 and XK 150 fitments are shown with the same size choices, the decision is less about sub-model separation and more about whether you want a traditional bias-ply setup or a radial tire in the proper wheel diameter.
175R16 is a Euro-metric radial size in which 175 refers to the nominal section width in millimeters, R identifies radial construction, and 16 is the wheel diameter in inches. On a 1955 Jaguar XK, this size represents the radial side of the fitment story and suits owners looking for a later-style radial format while keeping the correct 16-inch rim diameter. Its sizing language is more familiar to buyers comparing European radial options than older inch-based bias-ply sizes. It is worth evaluating when road use and construction choice are the main priorities, while still confirming wheel compatibility and overall clearance on the car itself.
600-16 is a numeric bias-ply size in which 600 indicates an approximate 6.00-inch nominal section width and 16 identifies the wheel diameter. For the 1955 Jaguar XK, it is the traditional period-style fitment and carries the visual character many restoration-minded owners want from a mid-1950s British sports car. Available choices include brands such as BFGoodrich, Firestone, Goodyear, Avon, Coker Classic, Excelsior, Lester, STA, Camac, and Ford Script, with blackwall, wide whitewall, and double-whitewall treatments across several tire series. It is the size to study closely when authentic appearance, classic construction, and 16-inch wheel compatibility are central to the decision.
Fitment is straightforward across the covered 1955 Jaguar XK sub-models because both use the same two 16-inch tire-size paths. Checking the exact sub-model still matters so the car can be matched to the owner's restoration goals, wheel setup, and preferred construction type.

1955 Jaguar XK 120 & 140
The 1955 Jaguar XK 120 & 140 uses the same two primary size choices, 175R16 radial and 600-16 bias-ply, both on 16-inch rims. That means the real decision is whether the car should keep a more traditional bias-ply presentation or move toward a radial setup after confirming wheel compatibility and overall fit.
The 1955 Jaguar XK 150 also follows the same fitment pattern, with 175R16 radial and 600-16 bias-ply options on 16-inch wheels. Tire selection comes down to the intended character of the car, whether that is restoration-oriented appearance or a radial construction choice that still respects the original rim diameter.
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.

Available 600-16 choices give the 1955 Jaguar XK owner a wide range of bias-ply options across BFGoodrich, Firestone, Goodyear, Avon, Coker Classic, and other brands. The product grid is most useful for comparing tire series, sidewall treatments such as blackwall or whitewall, and rim-width specifications where they are stated.
Owners researching 1955 Jaguar XK tires usually need clarity on the two primary 16-inch sizes, the difference between bias-ply and radial construction, and how to choose a tire that suits restoration goals, wheel fitment, and real road use.
Tire Size & Fitment
What tire size fits a 1955 Jaguar XK?
A 1955 Jaguar XK uses two primary tire sizes: 600-16 in bias-ply construction and 175R16 in radial construction. Both sizes are tied to 16-inch wheels, so the basic fitment choice is not wheel diameter so much as which construction style and sizing format best matches the car and the owner's goals.
That distinction matters because a bias-ply 600-16 gives the car a more traditional mid-century presentation, while a 175R16 places the XK in a radial format. Before choosing either one, verify that the wheels on the car are still the correct 16-inch setup and have not been changed during restoration or later ownership.
What size rim does a 1955 Jaguar XK use?
The 1955 Jaguar XK uses a 16-inch rim diameter with both of its primary tire sizes. The 600-16 bias-ply size and the 175R16 radial size are both built around that same 16-inch wheel diameter, which keeps the first fitment checkpoint simple.
Wheel diameter is only part of the picture, though. The car should also be checked for actual wheel width, especially if it has been restored, modified, or fitted with replacement wheels over the years, since tire construction and section shape can change how a tire sits and clears the body and suspension.
Do all 1955 Jaguar XK sub-models use the same tire size?
The covered 1955 Jaguar XK sub-models share the same primary tire choices. Both the XK 120 & 140 and the XK 150 are associated with 600-16 bias-ply and 175R16 radial fitments, all using a 16-inch rim diameter.
That makes sub-model selection less complicated than on many year-make-model pages, but it does not remove the need to inspect the actual car. A long-owned or restored XK may have different wheels than expected, so matching the tire to the wheel on the car remains just as important as matching the tire to the model name.
Choosing the Right Tire
What should I consider when choosing a 600-16 tire for a 1955 Jaguar XK?
Start with the role the car will play. A 600-16 bias-ply tire suits owners who want the traditional sizing format and visual character associated with a mid-1950s sports car, and this size is available across multiple brands, tire series, and sidewall treatments.
Selection becomes more specific once the basics are settled. Compare sidewall style, confirm rim-width suitability where it is stated, and look at the tire series that best matches the appearance you want, whether that means a simple blackwall or a more restoration-oriented whitewall presentation.
What sidewall styles are available for 1955 Jaguar XK tires?
For the 1955 Jaguar XK's 600-16 bias-ply size, available sidewall styles include blackwall, wide whitewall, and double-whitewall. Those choices can noticeably change the finished look of the car, even when the tire size and overall wheel diameter remain the same.
A blackwall usually gives the cleanest sporting appearance, while wide whitewall and double-whitewall options create a stronger period-style visual statement. Sidewall treatment should be chosen with the car's restoration direction in mind, rather than assuming any one style is automatically correct for every XK.
What brands offer tires for the 1955 Jaguar XK?
The 600-16 bias-ply fitment for a 1955 Jaguar XK is available from several brands, including BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those options span multiple tire series and appearance treatments rather than one single style of replacement.
Brand choice should be weighed alongside construction, sidewall style, and the character of the tire series itself. Some offerings are clearly aimed at traditional passenger-car presentation, while others lean toward military or truck-oriented patterns, so the best match depends on how the XK is being finished and used.
Restoration & Appearance
Which tire should I choose for a period-style 1955 Jaguar XK?
A 600-16 bias-ply tire is the most natural starting point for a period-style 1955 Jaguar XK because it preserves the vintage numeric sizing format and the traditional construction associated with cars of this era. It also opens up several visual directions through blackwall, wide whitewall, and double-whitewall options.
The final choice depends on how strictly the car is being restored and the kind of appearance you want at curbside. When exact originality matters, compare the tire against marque-club guidance, period photography, and restoration records rather than assuming that any sidewall treatment in the correct size is automatically historically exact.
Does correct tire fitment matter for a 1955 Jaguar XK restoration?
Correct tire fitment matters a great deal on a 1955 Jaguar XK restoration because tire size and construction strongly influence stance, visual balance, and the way the finished car reads as a mid-1950s Jaguar. Even small departures in size format or sidewall presentation can change the character of the car.
Matching the tire to the restoration approach also helps avoid problems later. A car built around a traditional bias-ply look may need a different visual strategy than one restored for frequent touring, so wheel diameter, tire construction, and sidewall style should all be checked before the final setup is chosen.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1955 Jaguar XK?
Yes, modifications can affect tire fitment on a 1955 Jaguar XK even when the nominal tire size appears correct. Replacement wheels, wheel-width changes, altered ride height, suspension work, or body repairs can all influence how a 600-16 or 175R16 tire sits in the wheel opening and clears nearby components.
A modified XK should be inspected as it actually sits today rather than by model designation alone. Check wheel diameter, wheel width, steering travel, and clearance at the fender and suspension, especially if the car has been lowered, fitted with non-stock wheels, or rebuilt from long-term project status.
What should I inspect before driving a 1955 Jaguar XK on new tires?
Before driving a 1955 Jaguar XK on new tires, inspect the wheels for the correct 16-inch diameter, check that the tires seat properly, and look over the valve stems, wheel hardware, and general suspension condition. On a collector car, it also makes sense to confirm there are no interference points at steering lock or normal ride height.
A short, careful test drive is the right next step. Watch for rubbing, vibration, or uneven behavior, then recheck tire pressure and visual clearance once the car returns to the garage, since restored or seldom-driven cars often reveal fitment issues only after the suspension has cycled under actual road use.
How should 600-16 or 175R16 tires on a collector 1955 Jaguar XK be maintained?
Collector-car tires on a 1955 Jaguar XK should be maintained with regular pressure checks, routine visual inspections, and close attention to aging even if tread wear is minimal. Low-use cars can develop problems from time, storage conditions, and inactivity long before they show the wear patterns seen on daily drivers.
Good storage habits help protect either size. Keep the car away from prolonged sunlight, excessive heat, moisture, and ozone sources, and inspect the tires for cracking, bulges, cuts, and air loss before each driving season or longer outing. Maintenance should reflect the car's real use pattern, not just mileage.
