1967 Jaguar 340 Tires

The 1967 Jaguar 340 uses two primary tire sizes: 185R15 in radial construction and 640-15 in bias-ply construction. Both fitment paths use a 15-inch rim, and both covered sub-models share these same size choices rather than having different trim-specific tire sizes.

That means the main decision is choosing the tire type and appearance that suit the car, not sorting through several unrelated fitments. A Jaguar kept close to period presentation may stay with 640-15 bias-ply, while a car set up for more regular road use may be evaluated with 185R15 radials after confirming wheel width and overall clearance.

The 1967 Jaguar 340 uses a 15-inch rim with both of its primary tire sizes. The 185R15 radial fitment and the 640-15 bias-ply fitment are both built around that same 15-inch wheel diameter, so the tire decision does not involve changing rim diameter between these primary size paths.

Wheel diameter is only one part of the fitment picture, though. Before selecting between the radial and bias-ply options, it is still smart to confirm the actual wheel width on the car, especially if the Jaguar has alloy wheels, replacement wheels, or a long ownership history that may have changed the original setup.

Yes. The covered 1967 Jaguar 340 Sedan and 1967 Jaguar 340 Sedan w/alloy wheels both use the same two primary tire fitment choices: 185R15 radial and 640-15 bias-ply. There is no separate size split between those sub-models within the covered fitment range.

That shared fitment makes the buying process simpler, but the current wheel setup still matters. A car that has been modified, fitted with different-width wheels, or converted from one tire construction to another should be checked carefully so the chosen tire works with the actual rim and leaves proper clearance at the fenders and steering components.

640-15 is a bias-ply tire size for the 1967 Jaguar 340. It is the traditional numeric sizing format used on many vintage applications, and it remains available in classic bias-ply product lines with blackwall, narrow whitewall, and wide whitewall presentations.

Choosing 640-15 usually comes down to preserving a period-style appearance and staying with a traditional construction type. Owners comparing it with the 185R15 radial option should also look at wheel width, intended road use, and the overall look they want, since construction choice changes both the visual character and the setup requirements.

Radial equivalents for 640-15 include 175R15, P175/75R15, and P185/70R15. Those represent three different radial sizing approaches: an 80-series metric radial, a 75-series P-metric radial, and a 70-series P-metric radial, all tied to the original 640-15 bias-ply size as comparison options.

The equivalent sizes give a buyer several ways to evaluate a radial alternative, but they should not be treated as automatic interchange choices. A recommended rim-width range of 5 to 6 inches applies here, and it is important to confirm the Jaguar’s actual wheel width, overall tire dimensions, and fender and steering clearance before making the switch.

Start by confirming which bias-ply size is on the car now and which radial size is being considered. For a 1967 Jaguar 340 moving from 640-15, the comparable radial options include 175R15, P175/75R15, and P185/70R15, while 185R15 is also a primary radial fitment used on this model.

The practical checks are wheel width, wheel condition, overall tire dimensions, and clearance through full steering travel and suspension movement. A Jaguar that has alloy wheels, replacement wheels, or suspension changes deserves extra attention, because the fact that a size is a radial equivalent does not by itself confirm that every wheel and body setup will accept it cleanly.

Begin with the basic fitment path: 640-15 if the goal is a bias-ply tire, or 185R15 if the car is staying with a radial setup. From there, compare construction type, rim-width suitability, sidewall appearance, and how closely the tire matches the car’s intended use, whether that is show presentation, occasional touring, or more frequent road driving.

The 1967 Jaguar 340 has meaningful variety within both sizes, so the decision is not just about dimensions. A buyer should also weigh brand, tire series, load figures where stated, and whether the car’s current wheels are standard, alloy, or aftermarket, since the right-looking tire still needs to work correctly with the actual wheel and chassis setup.

Sidewall choices for the 1967 Jaguar 340 include blackwall, narrow whitewall, wide whitewall, and redline, depending on the tire size and product line. The radial 185R15 options include blackwall, narrow whitewall, and redline, while the 640-15 bias-ply options expand the traditional look with blackwall, narrow whitewall, and wide whitewall versions.

That range gives the car very different visual personalities without changing the basic 15-inch fitment path. A subtle blackwall can suit a restrained sporting sedan look, while whitewall styles push the car toward a more formal vintage presentation; the best choice depends on the wheel design, restoration direction, and how closely the owner wants to echo a particular era of appearance.

Tires for the 1967 Jaguar 340 are available from Michelin, Avon, Coker Classic, Universal Vintage Tire, BFGoodrich, Firestone, and Excelsior. Those brands are spread across the two main fitment paths, with radial choices centered on 185R15 and bias-ply choices centered on 640-15.

Brand alone should not make the decision. It helps more to compare each tire by the correct size, construction, sidewall treatment, and series character, then narrow the field by wheel compatibility and the car’s intended use. That approach keeps the focus on selecting the right type of tire for the Jaguar rather than treating every product in the size range as interchangeable.

A period-style 1967 Jaguar 340 usually starts with the 640-15 bias-ply size, since that construction and numeric sizing deliver a more traditional visual and historic character. Blackwall, narrow whitewall, and wide whitewall bias-ply choices are all available, allowing the owner to move the car toward a sporting or more formal vintage appearance.

The best restoration-oriented choice depends on how strictly the car is being interpreted and what look the owner is trying to recreate. When exact originality matters, marque-specific references and historical vehicle documentation are worth checking, because a tire can be highly appropriate in size and era without automatically being the exact brand or sidewall treatment originally used.

Tire construction changes the restored look of a 1967 Jaguar 340 more than many buyers expect. A 640-15 bias-ply tire gives the car a more traditional mid-century presentation, while a 185R15 radial tends to look more modern in both casing shape and overall visual stance, even when offered with vintage-inspired sidewall treatments.

That difference matters because the Jaguar 340 sits at the intersection of sporting sedan character and formal British styling. A buyer choosing redline, blackwall, or whitewall treatment should consider how each complements the wheel design and the restoration theme, then decide whether the visual priority is authenticity of era, improved road-minded practicality, or a careful blend of both.

Yes. Modifications can affect tire fitment on a 1967 Jaguar 340 even when the tire size itself is correct for the model. Replacement wheels, alloy wheel variations, altered wheel width, suspension work, ride-height changes, or body repairs can all change how a 640-15 or 185R15 tire sits within the available space.

That is why the car should be checked as it exists today, not only by model year. Steering clearance, inner-fender space, and rim compatibility deserve attention before mounting new tires, especially when moving between bias-ply and radial construction or when evaluating one of the radial equivalents tied to the original 640-15 size.

Before driving a 1967 Jaguar 340 on new tires, inspect the wheels for condition and correct size, confirm proper mounting, and verify that each tire has clear space around suspension and body components. Tire pressure should be set appropriately for the tire and vehicle use, and the car should be checked for any obvious alignment or steering issues.

A short, careful test drive is a smart final step. Listen for rubbing, pay attention to steering response, and recheck pressure after the first outing. On an older Jaguar, it also helps to look over wheel bearings, suspension bushings, and brake components, since fresh tires can highlight problems that were less noticeable with old or deteriorated rubber.

Tires on a 1967 Jaguar 340 should be inspected regularly for pressure loss, tread wear, sidewall cracking, cuts, bulges, and signs of age-related hardening. Collector cars that spend long periods parked need extra attention because low annual mileage does not prevent rubber from aging, and stored cars can develop flat spotting or hidden deterioration.

Good maintenance also means protecting the tires from prolonged sunlight, excess heat, moisture, and ozone-producing equipment during storage. Keeping the Jaguar on clean, properly inflated tires and checking them before longer drives helps preserve both appearance and safety, whether the car is running traditional 640-15 bias-ply tires or 185R15 radials.
