1967 Morgan Tire Fitment Guide

1967 Morgan vehicles use four tire sizes across two model lines: 155R15, 560-15, 165R15, and 590-15. The 4-4 Series uses 155R15 and 560-15, while the Plus 4 uses those same two sizes plus 165R15 and 590-15. All four sizes fit 15-inch rims. Rim width guidance varies by size and product, with 155R15 commonly fitting 4.00 to 5.50-inch rims, 560-15 fitting around 4.5 to 5.50-inch rims depending on brand, 165R15 fitting 4.50 to 6.00-inch rims, and 590-15 fitting 4.00 to 4.50-inch rims where width guidance is given.

That means year and make alone are not always enough on a 1967 Morgan. A 4-4 Series owner can focus on the shared narrow radial or bias-ply choices, while a Plus 4 owner also needs to decide whether the wider 165R15 or 590-15 route better suits the car. Before choosing a tire, confirm the model and then compare the actual wheel width on the car to the rim-width range for the size you are considering.

On a 1967 Morgan, 560-15 is a classic numeric bias-ply size. The 5.60 portion refers to the nominal section width in inches, while the 15 identifies the wheel diameter in inches. Unlike a modern metric radial size, it does not spell out an aspect ratio in the code, and the construction is bias-ply rather than radial.

That matters because a 560-15 gives a very different character from a 155R15 or 165R15 radial even though all mount on 15-inch wheels. Owners choosing 560-15 are usually pursuing a more traditional visual profile and an older driving feel that suits a period sports car. Wheel width still needs to be checked, especially if the car has had wheel changes over the years.

No. The 1967 Morgan 4-4 Series and 1967 Morgan Plus 4 share 155R15 and 560-15, but only the Plus 4 reaches into 165R15 and 590-15. All of those sizes use 15-inch rims, so the difference is not wheel diameter alone. The distinction is in the model application, section width, and construction path available to that specific car.

That is why a Plus 4 owner has more room to tailor the tire choice than a 4-4 Series owner. If you know you have a Plus 4, you can compare narrow shared sizes with the wider Plus 4-only options before drilling down into brand and sidewall style. If you are still sorting out the exact model, identify that first so you do not narrow the search around a size meant only for the other Morgan.

Both sizes are correct paths for a 1967 Morgan 4-4 Series or Plus 4 where those shared fitments apply, but they represent different constructions. The 155R15 is a radial in a narrow metric format, while the 560-15 is a classic numeric bias-ply. The radial route is the better match for owners who want a more settled modern driving feel on the road, while the bias-ply route is the more era-authentic direction for a traditional restoration look and behavior.

The choice is less about rim diameter, since both are 15-inch sizes, and more about how you want the car to present and drive. A carefully restored Morgan used for shows or historically minded presentation often leans toward the bias-ply option. A Morgan that sees regular road use often leads owners toward the radial, especially if they value the manners of a modern reproduction tire more than strict period construction.

1967 Morgan tires span several sidewall styles depending on size. The 155R15 radial choices are blackwall only. The 560-15 bias-ply range includes narrow whitewall and wide whitewall versions, the 165R15 radial range includes blackwall, narrow whitewall, and wide whitewall versions, and the 590-15 bias-ply range includes blackwall and wide whitewall choices.

For a British sports car of this era, blackwall is often the most restrained and broadly period-appropriate visual direction, especially for owners aiming for an understated factory-style appearance. Whitewall choices can still make sense when an owner prefers a more customized presentation or is matching a particular restoration theme. The best approach is to choose the sidewall style after settling on the correct size and construction for your specific Morgan model.

1967 Morgan tire coverage includes Firestone, Michelin, US Royal, Coker Classic, American Classic, BFGoodrich, and Avon. In 155R15, the available brands are Firestone and Michelin. In 560-15, the brands are Firestone and US Royal. In 165R15, the available brands are Coker Classic, American Classic, Firestone, and BFGoodrich, while 590-15 is covered by BFGoodrich and Avon.

That spread gives Morgan owners a useful mix of traditional American collector-tire names and well-known European-style radial choices. Brand selection often narrows quickly once you choose a size and sidewall preference, so it helps to think in that order rather than starting with brand alone. If originality matters more than variety, focus first on the size and construction that best match your restoration goal and let the brand choice follow from there.

Rim width depends on the tire size chosen for a 1967 Morgan. The 155R15 radial commonly fits 4.00 to 5.50-inch rims. The 560-15 bias-ply appears on 4.5-inch rims in some versions and on a 4.50 to 5.50-inch range in others. The wider 165R15 radial fits 4.50 to 6.00-inch rims, while 590-15 bias-ply products that include rim guidance fit 4.00 to 4.50-inch rims.

Those differences are important because all of these tires share a 15-inch diameter but not the same ideal wheel width. A Morgan that has been fitted with replacement or aftermarket wheels may need a different choice than one still wearing its original rims. Measure the actual wheel width before ordering, especially when moving from a narrow shared size to one of the wider Plus 4-only options.

Inner tube requirements can vary within 1967 Morgan tire choices. In 155R15, Michelin offers both tube-type and tubeless versions, so that size does not have one universal answer. The 560-15 and 165R15 products here do not carry TT or TL variation in the same way, while the 590-15 options do not present a single tube-status pattern across the full group in a way that should be assumed without checking the specific sidewall marking.

The practical takeaway is to verify tube use at the product level rather than assuming all 15-inch Morgan tires are interchangeable in that respect. Wheel design also matters, especially on older British sports cars where wheel condition and air retention should be considered together. If the tire you choose is marked tube type, or if the wheel itself requires a tube, build that into the installation plan from the start.

All four tire sizes used on 1967 Morgan vehicles mount on 15-inch wheels, so there is shared rim diameter across the entire year and make. That means an original 15-inch Morgan wheel can be diameter-compatible with more than one tire size. Rim width still matters, though, because the narrow 155R15 and 560-15 sizes do not share the same width range as the wider 165R15 or the narrower-width 590-15 applications.

In practice, a 4-4 Series owner usually stays within the shared narrow-size lane, while a Plus 4 owner may be deciding whether the existing wheel width supports one of the broader model-specific options. The safest approach is to confirm both the wheel diameter and the wheel width before switching between sizes. That is especially important on a car that may have had wheel changes during restoration or long-term ownership.

A 1967 Morgan should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber. Keep the tires properly inflated, avoid parking on damp soil or bare concrete for long periods, and move the car occasionally so the load does not rest on one contact patch for months at a time. Bias-ply tires tend to take a temporary flat spot more readily during storage than radials.

That matters on a Morgan because collector cars often sit far longer than modern daily drivers. If the car will be parked for an extended season, rolling it periodically or supporting it appropriately can help preserve the shape of the tire and reduce stress on the carcass. A clean, shaded storage environment does as much for sidewall life as careful mileage management on a low-use sports car.

On a 1967 Morgan, tire age usually matters more than tread wear. Collector-car tires should be evaluated regularly once they reach roughly five to seven years of age, and replacement should become a serious consideration as they approach about ten years, even if the tread still looks good. The DOT date code on the tire is the practical reference point for age, not the date the car was restored or the date the tire was mounted.

Many Morgans cover limited annual mileage, so a tire can appear healthy while still aging out internally. Sidewall checking, hardening of the rubber, and a long period of static storage are often bigger concerns than simple tread depth. A time-based inspection routine is the best way to avoid overestimating the remaining life of a tire on a lightly used classic British sports car.

Tires on a 1967 Morgan should be inspected before every drive and again before any longer trip. Look for sidewall cracking, cuts, bulges, abnormal tread wear, and loss of air pressure, and make sure the valve stems are sound. If your chosen tire uses a tube-type arrangement, tube-related air retention and valve condition deserve the same attention as the outer casing.

A quick pre-drive inspection is especially valuable on an older sports car because small issues can turn into a roadside problem faster than they might on a modern vehicle. Longer trips call for a more thorough check, including the spare if the car carries one. Catching a crack, leak, or pressure problem before the car leaves the garage is one of the easiest ways to protect both the tires and the restoration.

A 1967 Morgan Plus 4 would have belonged to an era when bias-ply construction was still a normal original-equipment pattern on many sports cars, even as radials were becoming increasingly familiar in European applications. Within the sizes used on the Plus 4, both bias-ply and radial paths exist: 560-15 and 590-15 on the bias-ply side, and 155R15 and 165R15 on the radial side. The correct original direction for a specific car can depend on market, wheel setup, and restoration target.

For a historically exact restoration, start by matching the model first and then narrowing the tire by construction, size, and sidewall style. If the car is being judged, the expectation may be different for a factory-authentic presentation than for a sympathetically restored driver. A Morgan marque specialist or period sales literature can help confirm which of the Plus 4 size paths best aligns with your car’s intended standard.

Correct tire fitment absolutely matters when showing a 1967 Morgan, especially at events where authenticity is judged closely. Size, construction, and sidewall style all affect whether the car looks and presents as it should for the period. A radial on a car judged for strict originality, or a sidewall treatment that feels out of character for a British sports car of the era, can stand out even if the tire physically fits the wheel.

That does not mean every show car must wear the same tire, but it does mean the choice should be intentional. A touring-focused restoration can make different decisions from a concours-focused one without either approach being wrong in a broad sense. If points judging is the goal, use the event’s own standards and Morgan club guidance to settle questions of construction and sidewall appearance before the final tire choice is made.

For a 1967 Morgan in 155R15, Michelin X and Michelin XAS are both blackwall radial choices, but they are not the same specification. Michelin X appears here as a 155R15 82T TL tire, which means tubeless with a T speed rating up to 118 mph. Michelin XAS appears as a 155HR15 82H TT tire, which means tube type with an H speed rating up to 130 mph, and Michelin XAS-FF appears as a tubeless H-rated alternative in the same family.

That makes the difference more than branding alone. A Morgan owner comparing them should pay attention to tube requirement, speed rating, and whether the wheel setup favors a tube-type or tubeless solution. For an owner chasing a more specialized period-European radial character, the XAS family has a distinct place; for another owner, the simpler Michelin X specification may be the more straightforward fit.

1967 Morgan tires can be suitable for highway driving when they are in good condition, correctly inflated, and used within their intended speed capability. Among the radial choices in 155R15, available speed ratings include T at 118 mph and H at 130 mph. In 590-15, at least one Avon bias-ply option is H rated to 130 mph. Other bias-ply choices here do not always carry a speed symbol in the same way, so construction type and the exact tire selected both matter.

On a Morgan of this era, the tire’s speed capability is only one part of the highway equation. Suspension condition, steering play, brake performance, wheel condition, and the general temperament of a 1960s sports car matter just as much at real-world road speeds. A fresh, properly matched tire is a strong foundation, but the car should still be driven with the respect due an older lightweight sports machine.

Inflation pressure for a 1967 Morgan should be confirmed by the vehicle’s factory guidance first and then checked against the tire’s own load-and-pressure rating. Among these sizes, 560-15 bias-ply products carry 970 pounds at 32 psi, 165R15 radial products run at 1,168 pounds at 35 psi or 1,170 pounds at 36 psi depending on the tire, and 155R15 includes a Firestone radial at 1,045 pounds at 44 psi. Those figures describe the tire’s rated load at a stated pressure, not a universal inflation target for every Morgan setup.

That distinction is important because one size should never borrow a pressure figure from another. Vehicle weight distribution, wheel width, and the intended use of the car all influence the final pressure choice. Start with the car’s own specification, then make sure the selected tire is being operated within its rated pressure range and construction guidelines rather than inflating by guesswork.

Before a longer drive in a 1967 Morgan, inspect each tire for cracking, cuts, bulges, uneven wear, and correct inflation, and check that every valve stem is secure. If the car uses a tube-type tire, include the spare and its valve assembly in the inspection because age-related leakage can appear there first. Also confirm wheel fasteners, steering response, brake feel, and the general condition of the suspension and chassis before setting out.

A longer trip puts sustained heat and speed into tires that may spend much of their life on short local runs. That is why an older Morgan benefits from a deliberate walk-around rather than a casual glance. Verifying the tire condition before departure, instead of after the first fuel stop, reduces the chance that a small storage-related issue turns into a roadside interruption miles from home.
