The 1958 Jaguar XK sits in the final years of Jaguar’s great XK sports-car line, a period when British performance and long-distance touring character mattered as much as outright style. Whether the car is an XK 120, XK 140, or XK 150, tire choice plays a big role in how authentic and usable the car feels on the road. This fitment centers on 16-inch tires, with both 600-16 bias-ply and 175R16 radial options associated with the model range. That opens the door to traditional blackwall or whitewall bias-ply choices as well as a more modern radial-style alternative. The right selection depends on whether the goal is restoration-oriented appearance, road manners, or a careful balance of both.
Which Tire Size Is Right for The 1958 Jaguar XK
The 1958 Jaguar XK uses two primary tire sizes on a 16-inch rim: 600-16 in bias-ply construction and 175R16 in radial construction. Because both XK 120 & XK 140 and XK 150 are associated with these same sizes, the decision is less about sub-model separation and more about choosing the construction, appearance, and driving character that best matches the car’s present setup and intended use.
175R16 is a Euro-metric radial size, with 175 indicating nominal section width in millimeters, R identifying radial construction, and 16 indicating a 16-inch wheel. On a 1958 Jaguar XK, this size represents the radial side of the fitment and gives owners a modern metric sizing format tied to the same rim diameter as the bias-ply alternative. It is especially relevant for buyers who want to keep the 16-inch wheel while considering a radial-style setup instead of a traditional cross-era bias-ply presentation. Wheel width, overall dimensions, and clearance should still be confirmed on the actual car before making the change.
600-16 is a numeric bias-ply size, with the 600 designation representing an approximate 6.00-inch nominal section width and 16 indicating a 16-inch rim. For the 1958 Jaguar XK, it is the traditional bias-ply fitment and the size with the broadest visible product variety, including blackwall, wide whitewall, and double-whitewall choices. Available series include Coker Classic Bias Ply, Firestone Classic Bias Ply, BFGoodrich Silvertown Classic Bias Ply, Deluxe All-Weather, and several other period-style lines. This size makes the most sense when preserving a more traditional look and bias-ply character is the priority.
Fitment is straightforward across the covered 1958 Jaguar XK sub-models because the same two tire sizes appear throughout the range. Checking the exact sub-model still matters, but the main decision is choosing between the bias-ply and radial fitment paths on the 16-inch wheel.

1958 Jaguar XK 120 & XK 140
The 1958 Jaguar XK 120 & XK 140 are associated with both 175R16 radial and 600-16 bias-ply sizing on 16-inch rims. That gives the owner a clear choice between a traditional bias-ply presentation and a radial alternative, with wheel compatibility and the car’s current setup worth checking before changing construction.
The 1958 Jaguar XK 150 also uses the same pair of tire sizes, 175R16 radial and 600-16 bias-ply, on a 16-inch rim. Tire selection therefore comes down to the appearance and road-use character you want, along with careful confirmation of wheel width and clearance on the specific car.
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.

Owners of a 1958 Jaguar XK usually need clarity on 16-inch fitment, the difference between 600-16 bias-ply and 175R16 radial sizing, and how sidewall style or construction choice affects restoration goals and road use.
Tire Size & Fitment
What tire size fits a 1958 Jaguar XK?
A 1958 Jaguar XK is associated with two tire sizes: 600-16 in bias-ply construction and 175R16 in radial construction. Both sizes use a 16-inch rim, so the basic wheel diameter stays consistent even though the sizing systems and tire construction differ.
The practical choice is deciding whether the car should stay with a traditional bias-ply setup or move to a radial-format tire. That decision should be checked against the actual wheel width on the car, along with fender and steering clearance, especially if the Jaguar has been restored, modified, or fitted with replacement wheels over the years.
What size rim does a 1958 Jaguar XK use?
The 1958 Jaguar XK uses a 16-inch rim with both of its associated tire sizes, 600-16 and 175R16. That common rim diameter makes it easier to compare the bias-ply and radial fitment paths without changing the basic wheel size.
Rim diameter is only part of the fitment picture, though, because wheel width still matters when comparing actual tire choices. A 16-inch wheel can still vary in width or profile, so it is worth measuring the wheel already on the car before choosing between available products or changing from one tire construction type to the other.
Do all 1958 Jaguar XK sub-models use the same tire size?
The covered 1958 Jaguar XK sub-models share the same tire-size pattern. Both the XK 120 & XK 140 grouping and the XK 150 are associated with 600-16 bias-ply and 175R16 radial sizing on 16-inch wheels.
That consistency simplifies shopping because the key decision is not sub-model separation but tire type and presentation. It still helps to confirm the exact wheel fitted to the car today, since many collector Jaguars have seen wheel replacements, suspension work, or other changes that can influence how comfortably a given tire fits and clears.
Bias-Ply & Radial Options
Is 600-16 a bias-ply or radial tire for the 1958 Jaguar XK?
For the 1958 Jaguar XK, 600-16 is a bias-ply tire size. It uses a vintage numeric sizing format, and it is the traditional construction associated with many period-style replacement choices for this Jaguar fitment.
That matters because a bias-ply tire affects both appearance and vehicle feel in a different way than a radial. Owners who want a more traditional presentation often stay with 600-16, while those considering a radial should compare the separate 175R16 fitment and verify wheel width, clearance, and overall compatibility before changing construction.
Should I use bias-ply or radial tires on a 1958 Jaguar XK?
A 1958 Jaguar XK can be approached either with 600-16 bias-ply tires or with 175R16 radial tires, depending on the setup you want. Bias-ply preserves a more traditional tire style, while radial construction offers an alternative sizing format on the same 16-inch rim diameter.
The better choice depends on how the car is used and how closely the tire should reflect a restoration-oriented appearance. It is smart to look at the current wheels, suspension condition, and available space around the tire before deciding, particularly if the car has not remained in completely stock wheel and chassis form.
What should I check before converting my 1958 Jaguar XK from bias-ply to radial tires?
Before changing a 1958 Jaguar XK from 600-16 bias-ply to 175R16 radial tires, confirm that the car is still running the correct 16-inch wheels and that the wheel width suits the radial tire being considered. Clearance at the fenders, steering components, and suspension should also be reviewed carefully.
A construction change can alter how the tire sits on the wheel and how it behaves in use, even when the rim diameter is the same. It also makes sense to inspect the suspension, alignment, and overall condition of the car so the new tires are not being asked to compensate for worn parts or a compromised setup.
Choosing the Right Tire
What should I consider when choosing a 600-16 tire for a 1958 Jaguar XK?
Start with the basics: the tire should be a true 600-16 bias-ply for the traditional fitment path on a 1958 Jaguar XK, and it should match the 16-inch wheel on the car. From there, the meaningful choices become sidewall style, tire series, rim-width compatibility, load figures where stated, and the overall look you want.
The available assortment ranges from understated blackwalls to wide whitewalls and double-whitewalls, so appearance can change noticeably even within the same size. It also helps to separate passenger-car style bias-ply options from military or truck-oriented tread designs if the goal is a more appropriate sports-car presentation.
What sidewall styles are available for 1958 Jaguar XK tires?
For 600-16 fitment on a 1958 Jaguar XK, available sidewall styles include blackwall, wide whitewall, and double-whitewall. Those choices can change the car’s visual character significantly even when the tire size and basic bias-ply construction remain the same.
Blackwall usually gives the cleanest and most restrained presentation, while whitewall treatments create a more decorative period-style look. Since sidewall style is an appearance decision rather than a fitment change, the smarter comparison is between the visual effect you want and the series or brand options that carry that sidewall treatment in the correct size.
What brands offer tires for the 1958 Jaguar XK?
The 1958 Jaguar XK has 600-16 tire options from BFGoodrich, Coker Classic, Avon, Firestone, Goodyear, Lester, Excelsior, STA, Camac, and Ford Script. Most of those choices are bias-ply offerings, with differences appearing in tire series, sidewall treatment, and some rim-width or load specifications.
Brand alone should not be the only filter when comparing tires for this Jaguar. It is more useful to narrow the field by the kind of presentation you want, such as blackwall or whitewall, and then compare the tire series details and compatibility notes that matter for the wheel and driving use of the individual car.
Restoration & Appearance
Which tire should I choose for a period-style 1958 Jaguar XK?
For a period-style 1958 Jaguar XK, the 600-16 bias-ply fitment is the natural starting point because it preserves the vintage numeric sizing system and traditional tire construction associated with the car’s era. Within that size, there are blackwall, wide whitewall, and double-whitewall choices across several bias-ply series.
The right pick depends on how closely the car is being restored and the visual presentation you want at the wheel opening. If exact originality matters, period photographs, marque-club guidance, and model-specific historical references are worth consulting before settling on a brand or sidewall treatment.
How does tire construction affect the appearance of a restored 1958 Jaguar XK?
Tire construction changes more than road feel on a restored 1958 Jaguar XK; it also affects the car’s visual impression. A 600-16 bias-ply usually supports a more traditional vintage look, while a 175R16 radial introduces a later-style metric sizing format and a different overall presentation.
That does not automatically make one choice right and the other wrong. A restoration-oriented car often benefits from the visual character of a bias-ply tire, while a road-driven car may lead its owner toward a radial approach, provided the wheel dimensions and clearances are checked carefully before making the switch.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1958 Jaguar XK?
Yes, modifications can affect tire fitment on a 1958 Jaguar XK even when the nominal size remains 600-16 or 175R16. Aftermarket wheels, suspension changes, altered ride height, brake conversions, or body repairs can all change the available space around a tire and influence what works comfortably.
A car that no longer sits on its original-style wheel setup deserves a careful hands-on check before new tires are chosen. Measuring wheel width, confirming wheel diameter, and checking clearance at full steering lock can prevent surprises that a simple size code by itself does not reveal.
What should I inspect before driving a 1958 Jaguar XK on new tires?
Before driving a 1958 Jaguar XK on new tires, inspect the wheels for damage or corrosion, confirm the tires are seated correctly, and make sure inflation is set appropriately for the specific tire. It also helps to check lug security, steering response, and visible clearance around the fenders and suspension.
A short, careful initial drive is worthwhile so any rubbing, vibration, or pull can be caught early. Since many collector cars spend long periods parked, it is also sensible to inspect the rest of the chassis, including steering and suspension components, so the new tires are paired with a stable and roadworthy platform.
How should 600-16 tires on a collector 1958 Jaguar XK be maintained?
600-16 tires on a collector 1958 Jaguar XK should be maintained with regular pressure checks, routine visual inspections, and careful storage habits. Watch for sidewall cracking, flat spotting from long stationary periods, cuts, bulges, uneven tread wear, and slow air loss, especially on a car that is driven only occasionally.
Storage conditions matter almost as much as mileage on an older collector vehicle. Keeping the car away from prolonged heat, direct sunlight, excess moisture, and ozone sources helps preserve the tires, and moving or driving the Jaguar periodically can reduce stress from sitting in one position for too long.
