1967 Daimler Tire Fitment Guide

Three sizes cover 1967 Daimler vehicles: 185R15 radial, 640-15 bias-ply, and 700-16 bias-ply. The 2.5 Litre and Sovereign use the two 15-inch sizes, while the 4.5 Litre uses 700-16 on a 16-inch rim. For 185R15, rim-width guidance runs from 4.5 to 6.5 inches depending on the tire. For 640-15, rim-width guidance runs from 4.00 to 5.00 inches, and for 700-16 it reaches 4.50 to 5.50 inches on products that publish rim-width ranges.

That means the first step is identifying whether you have a 2.5 Litre, Sovereign, or 4.5 Litre. Owners of the smaller saloons then choose between two different constructions on the same 15-inch wheel diameter, while 4.5 Litre owners need the separate 16-inch fitment. Once the model is confirmed, compare the wheel's actual width to the tire's approved range before making a final selection.

On a 1967 Daimler, 185R15 is a metric radial size. The 185 refers to a nominal section width of 185 millimeters, the R indicates radial construction, and the 15 is the wheel diameter in inches. In this older metric format, the profile is conventionally understood as an 80-series radial unless a different ratio is stated directly on the tire.

For a 1967 Daimler 2.5 Litre or Sovereign, that decoding matters because 185R15 is not just another 15-inch tire; it represents a different construction philosophy from 640-15. The radial format generally appeals to owners who want a later-style driving character while keeping the proper wheel diameter. Sidewall appearance can also change within this size, since blackwall, narrow whitewall, and redline versions all exist.

No. The 1967 Daimler range splits into two fitment groups. The 2.5 Litre and Sovereign share 185R15 and 640-15, both of which mount on 15-inch wheels, while the 4.5 Litre uses 700-16 on a 16-inch wheel. That difference is fundamental enough that year and make alone are not sufficient for choosing tires across the whole Daimler lineup.

A buyer comparing the full model range should treat the 4.5 Litre separately from the two smaller saloons. If your car is a 2.5 Litre or Sovereign, your decision is largely about construction and appearance within a 15-inch fitment. If it is a 4.5 Litre, the decision starts with the correct 16-inch size and then moves to sidewall style, brand, and load-capacity preference.

For a 1967 Daimler 2.5 Litre or Sovereign, the choice between 185R15 and 640-15 is mainly a choice between radial and bias-ply construction on the same 15-inch wheel diameter. The 185R15 uses modern radial construction and comes in blackwall, narrow whitewall, and redline forms. The 640-15 is a traditional bias-ply size and is offered in wide whitewall and narrow whitewall styles, which can better match an earlier visual presentation.

Owners aiming for a more authentic mid-century tire look often gravitate toward the 640-15, especially for show-minded restorations. Drivers who want the feel commonly associated with radial construction often prefer the 185R15. Neither decision should be made by diameter alone, since both fit 15-inch wheels; the important question is whether your priority is period presentation, road feel, or a balance of the two.

1967 Daimler tires are available in several sidewall styles depending on size. The 185R15 radial range includes redline, narrow whitewall, and blackwall versions. The 640-15 bias-ply range includes wide whitewall and narrow whitewall versions. The 700-16 size for the 4.5 Litre is available in blackwall and wide whitewall form.

That variety matters because sidewall appearance often shapes the overall look of a restoration as much as the wheel itself. A blackwall usually gives the cleanest understated presentation, while whitewall widths can shift a car's appearance toward a more formal period-correct character. For a 1967 Daimler, the most convincing choice is usually the one that matches the car's intended market style, restoration goal, and the visual history of the particular model.

Several brands cover the 1967 Daimler range. In 185R15, the available names are Coker Classic and Michelin. In 640-15, BFGoodrich and Firestone cover the size. In 700-16, the available brands are Lester, Avon, BFGoodrich, and Firestone. The result is a mix of reproduction-focused American brands and established European-style touring options within the sizes that fit these cars.

Brand choice on a 1967 Daimler often comes down to the balance between visual authenticity, preferred sidewall treatment, and the construction you want to run. Michelin in 185R15 points toward a traditional European radial character, while Firestone, BFGoodrich, Lester, Avon, and Coker Classic span classic-looking bias-ply and reproduction categories. Once your model and size are settled, compare the exact sidewall style and published fitment details rather than choosing by brand name alone.

Rim-width guidance for 1967 Daimler tires varies by size and sometimes by individual product. The 185R15 radial range fits rims from 4.5 to 6.5 inches wide depending on the tire. The 640-15 bias-ply range covers 4.00 to 5.00 inches. In 700-16, products that publish fitment guidance call for 4.50 to 5.50 inch rims.

That spread is wide enough that wheel measurement matters, especially on cars that may have had wheels changed during earlier restorations. Even when two tires share the same wheel diameter, they may not share the same approved rim-width window. Measuring the wheel before purchase is the cleanest way to avoid mounting a tire on a rim that is either too narrow or too wide for the product you want.

Inner-tube requirements are not the same across the 1967 Daimler range. The 185R15 radial products are tubeless, marked TL on the examples that carry a tube designation. The 640-15 and 700-16 bias-ply products do not consistently publish a tube marking in the size description, so tube use should be confirmed against the exact tire and wheel combination rather than assumed from size alone.

That distinction is especially important on older wheels, where the wheel design and condition can be just as important as the tire itself. A tubeless radial still needs a wheel suitable for tubeless service, and a bias-ply setup may call for a tube depending on the specific tire and rim. Checking the tire marking and the wheel's construction before mounting is the right way to avoid compatibility surprises.

For the 1967 Daimler 2.5 Litre and Sovereign, both 185R15 and 640-15 share the same 15-inch rim diameter, so the wheel diameter itself is compatible with either size. Rim width still matters, though. The 185R15 range spans roughly 4.5 to 6.5 inches depending on product, while the 640-15 range is narrower at 4.00 to 5.00 inches.

In practical terms, many original 15-inch wheels can work with either size, but that should never be assumed without checking the actual rim width. A wheel that is appropriate for a narrow bias-ply may not be ideal for every radial in the same diameter. If the car has replacement wheels from an earlier restoration, measure first and then match the tire to the wheel rather than the other way around.

A 1967 Daimler should be stored out of direct sunlight, away from electric motors, battery chargers, welders, and other ozone-producing equipment, and in a dry space with stable temperatures. Keep the tires clean and properly inflated during storage. Bias-ply tires such as 640-15 and 700-16 can flat-spot more readily during long static periods, while any older-style collector tire can develop cosmetic aging more quickly if left under full load without movement.

Short monthly movement helps, and for longer storage many owners either reposition the car periodically or support it in a way that reduces sustained load on one contact patch. Tire covers can help when the storage area is bright. A 1967 Daimler that sits for seasons at a time benefits from the same care as the paint and interior, because storage conditions strongly influence sidewall life and ride quality once the car returns to the road.

On a 1967 Daimler, tire life is usually judged by age and condition more than mileage. Collector cars often wear very little tread, but the rubber still ages. A useful rule is to begin careful evaluation around five to seven years and to treat ten years as a point where replacement deserves serious consideration regardless of tread depth. The DOT date code on the tire sidewall is the baseline for that age check.

A low-mileage Daimler that looks fine in the garage can still have hardened rubber, internal aging, or sidewall cracking that limits real roadworthiness. Regular use, storage quality, climate, and inflation habits all influence service life. If the tires came with the car and their age is unclear, confirming the date code before a touring season is one of the simplest and most important maintenance steps you can take.

Tires on a 1967 Daimler should be inspected before every drive and more thoroughly before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, tread separation, and pressure loss. On cars using older wheel and tire combinations, also pay attention to valve-stem condition and the wheel's bead area. If a tube is part of the setup, the valve stem deserves especially close attention because it can reveal tube stress or shifting.

A quick pre-drive walkaround catches many of the problems that strand seldom-driven collector cars. A longer inspection before a tour or highway trip is worthwhile even if the car has been indoors, because age-related issues can appear long before the tread wears out. Keeping a written log of tire age, pressures, and any visible changes makes it easier to spot slow deterioration over time.

For a 1967 Daimler 2.5 Litre, both 185R15 radial and 640-15 bias-ply fitments are associated with the model today. By the late 1960s, radial tires were already well established in many European applications, while bias-ply construction still remained part of the period landscape depending on market, specification, and owner preference. That means original-fit research on a 1967 Daimler should focus not just on size, but on whether the car's intended presentation is tied to a radial-era European touring character or an earlier bias-ply appearance.

For restoration work, the safest approach is to compare the car's surviving wheels, handbook material, and any original placards with marque-club knowledge specific to the 2.5 Litre. A judge or knowledgeable enthusiast may notice both construction and sidewall style, not just diameter. If your goal is authenticity, use the tire size on the car as a starting point rather than the final answer, especially if the car has changed hands or countries over the years.

Correct tire fitment can matter a great deal when showing a 1967 Daimler, especially in preservation, concours, or marque-judged settings. Judges and knowledgeable enthusiasts often look at overall size, construction type, and sidewall treatment because those details strongly affect how period-correct the car appears. On a car from 1967, a modern-looking radial can read differently from a classic bias-ply even when both fit the same wheel diameter, and an incorrect whitewall style can change the visual era of the car.

The practical question is what kind of show standard your Daimler will be held to. A local driver-level event may be more forgiving than a marque-specific concours. Before finalizing a tire, compare it with period photos and seek guidance from Daimler or Jaguar-Daimler club members who know the expectations for your exact model and market. That helps you avoid spending time and money on a tire that looks right mechanically but wrong in presentation.

Within 185R15 for a 1967 Daimler, Michelin XVS and Coker Classic differ in sidewall presentation, fitment range, and speed-rating options. Coker Classic appears here as a redline radial with a 5.00 to 6.50 inch rim-width range and a published load figure of 1,355 pounds at 35 psi. Michelin XVS comes in narrow whitewall and blackwall forms, spans either 4.5 to 6 inches or 5.00 to 6.50 inches depending on version, and appears with H and V speed ratings.

That makes the choice less about one being universally better and more about what kind of 1967 Daimler you are building. A redline creates a distinctly different visual effect from a blackwall or narrow whitewall, while the Michelin options bring more variation in sidewall style and speed category. If your car is judged for authenticity or aimed at a particular touring presentation, those visual and specification differences are worth weighing carefully.

1967 Daimler tires can be appropriate for highway driving when the tire's condition, construction, and speed rating match the way the car is used. In 185R15, Michelin examples appear with H and V ratings, equal to 130 mph and 149 mph respectively. In 700-16, an Avon example carries an L rating, equal to 75 mph. The bias-ply 640-15 examples here do not publish a speed letter in the visible size description, so their intended use should be judged by the manufacturer's guidance and the car's operating conditions.

Real-world safety in a 1967 Daimler depends on more than the tire alone. Brake condition, steering wear, suspension health, alignment, and the car's age all play a major role, especially on long drives. Even when the tire's speed capability exceeds normal road speeds, an older Daimler is still best treated as a vintage machine rather than a modern high-speed cruiser. Match the tire to the way the car will actually be driven.

Inflation pressure for a 1967 Daimler should begin with the car's factory recommendation for the exact model and then be checked against the tire's own published rating. Among the tires here, 185R15 includes a maximum load of 1,355 pounds at 35 psi on one radial example. The 640-15 range includes 970 pounds at 32 psi and 1,190 pounds at 32 psi, while 700-16 examples reach 1,800 pounds at 36 psi, 1,874 pounds, and 1,900 pounds at 36 psi depending on the product.

Those figures are not universal running pressures for every 1967 Daimler; they are tire-specific load-and-pressure references. Actual driving pressure depends on the model, axle load, and the exact tire selected. Use the owner's manual or factory placard for the starting point, then confirm that your chosen tire is being used within its published limits. Never transfer a pressure figure from one size or product line to another just because the car make is the same.

Before taking a 1967 Daimler on a longer drive, inspect each tire for cracks, cuts, bulges, unusual wear, and proper pressure, then check the spare as well. Look closely at valve stems, especially on any older wheel-and-tube combination, and make sure the tires are seated properly and have no sign of sidewall injury. If the car has been sitting, pay attention to flat-spotting and any vibration that suggests age-related internal changes.

A longer trip also calls for a broader mechanical check because tire safety is only one part of vintage-car readiness. Wheel-bearing play, brake function, cooling-system health, and steering response all matter on a 1967 Daimler. The best pre-tour habit is to treat the tires as part of a full roadworthiness routine rather than an isolated item, especially if the car is driven infrequently between events.
