The 1959 Jaguar XK sits at the close of one of Jaguar’s most admired sports-car lines, a family known for graceful coachwork, long-bonnet proportions, and serious high-speed touring character. Whether the car is an XK 120, 140, or 150, tire choice shapes both its stance and the way it presents on the road. This Jaguar XK uses either a 600-16 bias-ply tire or a 175R16 radial, both on 16-inch rims. That gives owners a meaningful decision between traditional bias-ply appearance and a later-style radial approach, along with choices in brand, tire series, and sidewall treatment. The right selection starts with the construction and look that best suit the car’s restoration goals and intended driving use.
Which Tire Size Is Right for The 1959 Jaguar XK
The 1959 Jaguar XK uses two primary tire sizes, and the difference is construction rather than wheel diameter, since both sizes mount on 16-inch rims. The first step is confirming whether your car is set up for a 600-16 bias-ply tire or a 175R16 radial, then choosing the product style, brand, and sidewall treatment that match your driving plans and presentation goals.
A 175R16 size uses a 175-millimeter nominal section width, radial construction, and a 16-inch rim diameter. On a 1959 Jaguar XK, this size represents the radial fitment path and gives owners a period-appropriate metric radial format rather than an older numeric bias-ply size. The code does not state an aspect ratio, so it follows the traditional Euro-metric radial convention commonly associated with this type of sizing. This is the size to evaluate if the car already uses radial tires or if the goal is a 16-inch radial fitment within the supported Jaguar XK tire options.
A 600-16 tire is a vintage numeric bias-ply size, with the 600 indicating an approximate 6.00-inch nominal section width and the 16 identifying wheel diameter. For the 1959 Jaguar XK, it is the traditional bias-ply fitment and carries the more upright vintage look many restoration-minded owners want. This size is available across a broad mix of brands and tire series, with blackwall, wide whitewall, and double-whitewall choices depending on the product line. It is the size to consider when maintaining classic bias-ply construction, traditional sidewall styling, and a more period-style visual presentation.
Fitment is straightforward across the covered 1959 Jaguar XK sub-models because each one uses the same two tire-size paths. Checking the exact sub-model still helps confirm whether the car is being kept in a bias-ply configuration or has been set up with radial tires on its 16-inch wheels.

1959 Jaguar XK 120 & 140
The 1959 Jaguar XK 120 & 140 uses the same 175R16 radial and 600-16 bias-ply fitment choices found elsewhere in the XK range. That keeps tire selection focused on construction, appearance, and product style rather than on finding a different wheel diameter or sub-model-only tire size.
The 1959 Jaguar XK 150 also uses 175R16 radial and 600-16 bias-ply tire options on 16-inch rims. The decision here is less about size differences and more about whether the car should keep a traditional bias-ply presentation or use a radial setup that still matches the wheel 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.
Best 1959 Jaguar XK Tires for Sale
Available 600-16 choices span BFGoodrich, Coker Classic, Avon, Firestone, Goodyear, Excelsior, Lester, STA, Camac, and Ford Script. Buyers can compare bias-ply tire series, blackwall and whitewall treatments, and rim-width specifications that vary slightly by product.
These 1959 Jaguar XK tire questions focus on the two supported sizes, the difference between 600-16 bias-ply and 175R16 radial fitment, and the product, appearance, and maintenance details that matter before putting a collector Jaguar back on the road.
Tire Size & Fitment
What tire size fits a 1959 Jaguar XK?
A 1959 Jaguar XK uses either a 175R16 radial tire or a 600-16 bias-ply tire. Both sizes are associated with this model range and both use a 16-inch rim, so the fitment question is really about construction as much as size.
That matters because a car already set up for radial tires may not be the same as one being kept in a traditional bias-ply configuration. Checking the wheel, the tire already on the car, and the overall restoration goal will help determine which of the two supported sizes makes the most sense before comparing brands or sidewall styles.
What size rim does a 1959 Jaguar XK use?
The supported tire sizes for a 1959 Jaguar XK use a 16-inch rim. Both the 175R16 radial and the 600-16 bias-ply fitments share that same rim diameter, so wheel diameter stays consistent even though the tire sizing system changes.
Rim diameter is only one part of the fitment picture, especially on a collector car that may have had wheels changed over time. It is still worth confirming the actual wheel width and the setup currently on the car before moving from one construction type to another or selecting among products with different rim-width recommendations.
Do all 1959 Jaguar XK sub-models use the same tire size?
Yes. The covered 1959 Jaguar XK 120 & 140 and 1959 Jaguar XK 150 sub-models share the same two fitment paths: 175R16 in radial construction and 600-16 in bias-ply construction. There is no separate sub-model-only primary size within this group.
That simplifies shopping, but it does not remove the need to inspect the car itself. A Jaguar that has been restored, converted, or fitted with different wheels may lead you toward one supported construction choice over the other, so the final decision should still reflect the current wheel setup and the appearance you want to preserve.
Bias-Ply & Radial Options
Is 600-16 a bias-ply or radial tire for the 1959 Jaguar XK?
On a 1959 Jaguar XK, 600-16 is the bias-ply fitment. It uses the older numeric sizing format associated with vintage bias-ply tires, while 175R16 represents the radial fitment in the supported 16-inch Jaguar XK tire choices.
That distinction affects both appearance and selection. A 600-16 bias-ply keeps the traditional sizing format and opens the door to several classic series and sidewall treatments, while a radial setup follows a different construction path. Before changing from one to the other, confirm the actual wheels on the car and make sure the tire choice suits its intended use.
Should I use bias-ply or radial tires on a 1959 Jaguar XK?
A 1959 Jaguar XK supports both directions: 600-16 as the bias-ply choice and 175R16 as the radial choice. The better option depends on what matters most for the car, whether that is preserving a traditional vintage presentation or maintaining a setup already using radial construction.
The most useful way to decide is to start with the car’s current wheel and tire arrangement, then consider how the Jaguar will be driven and shown. A restoration-oriented car often favors the visual character of a bias-ply tire, while a road-driven car already wearing radial-compatible equipment may point toward staying with the radial size.
What should I check before converting my 1959 Jaguar XK from bias-ply to radial tires?
A conversion from 600-16 bias-ply to 175R16 radial starts with the basics: confirm the 16-inch wheel diameter, inspect actual wheel width, and make sure the car’s current setup is appropriate for a radial tire. Clearance around the fenders and steering range should also be reviewed before making the change.
Construction changes can alter how the car sits and feels even when the rim diameter remains the same. It is also smart to inspect suspension condition, alignment, and any prior modifications before switching, especially on an older Jaguar that may have seen restoration work or wheel changes over the years.
Choosing the Right Tire
What should I consider when choosing a 600-16 tire for a 1959 Jaguar XK?
Start by making sure 600-16 is the construction path you want, since it is the bias-ply fitment for the 1959 Jaguar XK. From there, compare the available tire series, sidewall treatments, rim-width recommendations where stated, and load figures when those details matter to the way the car will be used.
This size includes a wide spread of product character, from simple blackwall presentation to more decorative whitewall and double-whitewall styles. The best choice usually comes down to how original-looking or understated the car should appear, whether it is driven lightly or more often, and how closely the tire suits the wheel already on the car.
What sidewall styles are available for 1959 Jaguar XK tires?
The 600-16 options for a 1959 Jaguar XK include blackwall, wide whitewall, and double-whitewall sidewall styles. Those choices give the car a very different visual character even when the tire size stays the same, so sidewall treatment is an important part of selecting the right bias-ply tire.
A blackwall usually gives the XK a more restrained sporting look, while whitewall styles add a dressier period-style presentation. Since sidewall appearance is highly visible on a restoration, it helps to choose that look early, then narrow the search by brand, tire series, and wheel compatibility rather than treating appearance as an afterthought.
What brands offer tires for the 1959 Jaguar XK?
The 600-16 fitment for a 1959 Jaguar XK is available from BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those brands appear across several different bias-ply tire series, so the selection is broader than a single look or tread style.
Brand alone should not drive the decision. It makes more sense to compare the exact tire series, sidewall presentation, rim-width specification when stated, and whether the tire’s overall character matches a sporting road car, a more formal restoration theme, or a specialty use pattern that calls for a particular style of bias-ply construction.
Restoration & Appearance
Which tire should I choose for a period-style 1959 Jaguar XK?
For a period-style 1959 Jaguar XK, the 600-16 bias-ply size is the natural starting point because it preserves the vintage numeric sizing format and traditional construction. Within that size, the available choices vary by tire series and sidewall treatment rather than by a change in wheel diameter.
That does not make every 600-16 visually identical, so it helps to decide whether the car should wear a simpler blackwall or a more decorative whitewall presentation. When exact originality matters, compare the final choice against marque-club guidance, period photography, or restoration records rather than assuming any current offering matches factory delivery.
How does tire construction affect the appearance of a restored 1959 Jaguar XK?
Tire construction has a noticeable effect on how a restored 1959 Jaguar XK presents, even before the car moves. A 600-16 bias-ply keeps the older sizing language and a more traditional vintage look, while a 175R16 radial gives the car a later-style metric radial presentation on the same 16-inch rim diameter.
That visual difference is important on an XK because the tire sits prominently within the car’s classic proportions. Owners aiming for a more restoration-oriented appearance often begin with the bias-ply option, while those prioritizing a radial setup should still choose a tire that looks appropriate for the car’s era and overall finish.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1959 Jaguar XK?
Yes. A 1959 Jaguar XK may use supported 16-inch tire sizes, but aftermarket wheels, different wheel widths, suspension changes, ride-height alterations, or bodywork repairs can all affect how either a 600-16 bias-ply or 175R16 radial sits on the car. Even small setup changes can influence clearance and overall suitability.
That is why the actual car should be checked before assuming a familiar size is the right answer. Steering clearance, fender space, and the wheel already installed deserve attention, especially on older restored vehicles where components may no longer match original specifications or may have been changed during previous ownership.
What should I inspect before driving a 1959 Jaguar XK on new tires?
Before driving a 1959 Jaguar XK on new tires, inspect the wheels for condition and correct diameter, verify proper mounting, and check that the tires clear through full steering movement. It is also wise to look over the suspension, alignment, and valve stems so the new tires are not being asked to compensate for other problems.
Road-readiness on a collector Jaguar also means watching tire pressure, confirming there are no sidewall cuts or shipping damage, and rechecking the installation after a short initial drive. An older car that has sat for long periods benefits from an especially careful review before heading out for sustained road use.
How should 600-16 or 175R16 tires on a collector 1959 Jaguar XK be maintained?
Collector-car tires on a 1959 Jaguar XK should be maintained with regular pressure checks, periodic visual inspections, and careful storage habits. Whether the car wears 600-16 bias-ply tires or 175R16 radials, owners should watch for cracking, bulges, tread damage, and signs of air loss that can develop even on lightly driven vehicles.
Storage conditions matter almost as much as mileage on a classic Jaguar. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and occasional inspection of wheel condition and clearance can catch problems early before a show trip or longer road outing.
