The 1958 Jaguar Mark belongs to the big postwar Jaguar saloon tradition, blending formal British luxury with the strong road manners that helped these cars stand apart from many contemporaries. For owners today, tire choice matters because the car sits at the meeting point between traditional restoration practice and more modern touring use. The 1958 Jaguar Mark uses either a 670-16 bias-ply tire or a 185R16 radial, both on 16-inch rims. That creates a meaningful decision between period-style bias-ply presentation and radial construction from Michelin, Avon, or Vredestein. The right choice depends on how closely the car is being restored, how it will be driven, and which wheel setup is actually on the car.
Which Tire Size Is Right for The 1958 Jaguar Mark
The 1958 Jaguar Mark uses two primary tire sizes, and the difference is tied mainly to construction rather than wheel diameter. Both the 670-16 bias-ply and the 185R16 radial fit a 16-inch rim, so the first step is confirming whether the car is set up for traditional bias-ply tires or for radial use before comparing brand, series, and wheel-width compatibility.
185R16 is a Euro-metric radial size in which 185 is the nominal section width in millimeters, R identifies radial construction, and 16 is the rim diameter in inches. On a 1958 Jaguar Mark, this size represents the radial side of the fitment and suits owners looking for a more modern tire format while staying with a 16-inch wheel. Available choices include Michelin, Avon, and Vredestein, all in blackwall form and spread across series such as Michelin X Radial, Turbosteel CR6D, and Sprint Classic. It is a useful size to evaluate when road use, wheel compatibility, and a classic radial appearance all matter.
670-16 is a numeric bias-ply size in which 670 refers to an approximate 6.70-inch nominal section width and 16 identifies the rim diameter. For the 1958 Jaguar Mark, this is the traditional bias-ply fitment and keeps the car in a period-style construction that many restoration-minded owners prefer. Blackwall options are available from Firestone and Avon in series including Firestone Classic Bias Ply and Turbospeed Mk4. This size deserves close attention when maintaining a more original-era look or when the car still uses wheels better matched to bias-ply specifications.
Fitment is straightforward across the covered 1958 Jaguar Mark 7, 8 & 9 sub-model grouping because the same two tire sizes appear throughout. Checking the exact sub-model still matters, but the bigger decision is whether the car remains on bias-ply tires or has been set up for radial use.

1958 Jaguar Mark 7, 8 & 9
The 1958 Jaguar Mark 7, 8 & 9 grouping uses the same two 16-inch tire choices: a 670-16 bias-ply or a 185R16 radial. That keeps size selection relatively simple and shifts the focus toward construction, wheel-width suitability, and whether the car is being kept in a more restoration-oriented or road-use-oriented setup.
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 1958 Jaguar Mark Tires for Sale
Available 1958 Jaguar Mark tires span both 185R16 radial and 670-16 bias-ply fitments, with blackwall choices from Michelin, Avon, Firestone, and Vredestein. The product grid is where to compare construction, tire series, and wheel-width compatibility for the exact setup on the car.
Common 1958 Jaguar Mark tire questions usually center on the difference between 670-16 and 185R16, 16-inch rim fitment, bias-ply versus radial selection, and what to inspect before putting a collector Jaguar back on the road.
Tire Size & Fitment
What tire size fits a 1958 Jaguar Mark?
The 1958 Jaguar Mark uses two primary tire sizes: 670-16 in bias-ply construction and 185R16 in radial construction. Both sizes are associated with the covered Jaguar Mark 7, 8 & 9 applications, so the car may be encountered with either setup depending on how it has been maintained or restored.
The practical question is not just size, but which construction matches the wheels and the way the car is intended to be used. A buyer should confirm whether the car is staying with a period-style bias-ply arrangement or using a radial setup, then compare rim-width suitability and physical clearance before making a final tire choice.
What size rim does a 1958 Jaguar Mark use?
The tire fitments used on a 1958 Jaguar Mark are built around a 16-inch rim diameter. Both the 670-16 bias-ply size and the 185R16 radial size share that same 16-inch wheel diameter, which keeps the basic wheel-size question simple even though the tire constructions differ.
Rim diameter is only one part of fitment, so it is still important to check the actual wheel width on the car before choosing a tire. Some 185R16 radial products call for wider rim ranges than the 670-16 bias-ply choices, and that difference can affect which tire is the better match for the existing wheels.
Do all 1958 Jaguar Mark sub-models use the same tire size?
Across the covered 1958 Jaguar Mark 7, 8 & 9 grouping, the same two tire sizes appear: 670-16 in bias-ply form and 185R16 in radial form. That means the sub-model grouping does not introduce a separate wheel diameter or a completely different primary fitment to sort through.
Even with shared size options, the car itself should still be checked before replacement. A Jaguar that has already been converted to radial tires, fitted with different wheels, or restored with a particular appearance goal may point you toward one construction more naturally than the other.
Choosing the Right Tire
What should I consider when choosing a 1958 Jaguar Mark tire?
Start with the correct primary setup for the car: 670-16 if it is staying with bias-ply construction or 185R16 if it is using radial tires. From there, the meaningful differences are wheel-width compatibility, brand, tire series, and whether the goal is a more traditional presentation or a classic radial road-tire approach.
A restoration-focused Jaguar may lean toward the 670-16 bias-ply format, while a road-driven car may be better suited to 185R16 radial choices. It also helps to compare product details such as maximum load figures where stated, overall tire character, and whether the current wheel setup supports the tire under consideration.
What brands offer tires for the 1958 Jaguar Mark?
The 1958 Jaguar Mark has tire choices from Michelin, Avon, Vredestein, and Firestone. The 185R16 radial size includes Michelin X Radial, Avon Turbosteel CR6D, and Vredestein Sprint Classic, while the 670-16 bias-ply size includes Firestone Classic Bias Ply and Avon Turbospeed Mk4.
Brand choice should follow the size and construction that belong on the car rather than the other way around. Once that is settled, compare each product's series, stated wheel-width compatibility where given, and the sort of visual and driving character that best matches the Jaguar's restoration goals and intended use.
How do I choose between the available 185R16 and 670-16 tires for a 1958 Jaguar Mark?
The biggest difference is construction. A 670-16 keeps the car in a traditional numeric bias-ply format, while a 185R16 moves it into a Euro-metric radial setup on the same 16-inch rim diameter. Within those sizes, the available products vary by brand, series, and some wheel-width ranges.
A useful way to decide is to look at the whole car rather than the tire alone. Check the wheel width, consider whether the Jaguar is being restored for period-style appearance or regular road driving, and compare the product details closely enough to avoid mixing a tire choice with an unsuitable wheel setup.
Restoration & Appearance
Which tire should I choose for a period-style 1958 Jaguar Mark?
For a period-style 1958 Jaguar Mark, the 670-16 bias-ply size is the most traditional starting point. That size keeps the car in the vintage numeric bias-ply format associated with its era and is available in blackwall form from Firestone and Avon, both of which suit a restrained, formal saloon presentation.
Exact originality can depend on details beyond size alone, so owners pursuing a highly exact restoration should compare the tire choice against marque references and vehicle-specific historical guidance. For many cars, though, staying with the proper bias-ply size and an appropriate blackwall look is the clearest path toward an authentic period impression.
How does tire construction affect the appearance of a restored 1958 Jaguar Mark?
Tire construction changes both the look and the stance of a restored 1958 Jaguar Mark, even when the rim diameter stays at 16 inches. A 670-16 bias-ply gives the car a more traditional presentation, while a 185R16 radial introduces a later-style metric sizing format and a different visual character.
That does not make one choice universally right or wrong; it depends on the restoration goal. Owners building a historically sympathetic car often start with the bias-ply format, while those prioritizing touring use may accept the radial appearance in exchange for a different driving setup and broader radial brand selection.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1958 Jaguar Mark?
Yes, modifications can change tire fitment on a 1958 Jaguar Mark even when the car still uses a 16-inch wheel. Aftermarket wheels, non-stock wheel widths, suspension changes, and body or steering alterations can all affect whether a 670-16 bias-ply or 185R16 radial remains a sensible choice.
Any Jaguar that has been altered should be measured rather than assumed. Check actual wheel width, inspect inner and outer clearance at full steering lock, and make sure the tire under consideration suits the car's present configuration instead of relying on what would have been appropriate for a standard setup.
What should I inspect before driving a 1958 Jaguar Mark on new tires?
Before putting a 1958 Jaguar Mark back into regular road use on new tires, inspect the wheels, valve stems, and overall wheel condition, then verify that the tire size and construction match the setup on the car. It also makes sense to look over suspension, steering components, and basic alignment condition.
A fresh set of tires cannot compensate for cracked wheels, worn front-end parts, or clearance issues that show up only under load or during turns. Once mounted, monitor tire pressure closely, recheck for rubbing or uneven wear, and keep an eye on how the Jaguar settles after the first few drives.
How should tires on a collector 1958 Jaguar Mark be maintained?
Collector-car tires on a 1958 Jaguar Mark should be maintained with regular pressure checks, visual inspection, and careful storage habits. Even if tread wear is minimal, age, sidewall cracking, bulges, cuts, and slow air loss matter on a low-mileage classic just as much as mileage-based wear does.
Cars that spend long periods parked benefit from a clean, dry storage area away from strong sunlight and ozone-producing equipment. It also helps to move the car occasionally, inspect the tires before every road outing, and have any questionable condition reviewed before trusting the Jaguar on a longer drive.
