1960 Morgan Tire Fitment Guide

1960 Morgan vehicles use two tire sizes across the full model range: 155R15 and 560-15. Both the 1960 Morgan 4-4 Series and 1960 Morgan Plus 4 use those same two sizes, and both mount on 15-inch wheels. For 155R15, the radial products fit 15-inch rims and commonly call for rim widths from 4.00 to 5.50 inches. For 560-15, the bias-ply products fit 15-inch rims with rim width guidance centered around 4.5 inches, with some versions covering 4.50 to 5.50 inches.

That makes 1960 Morgan fitment simpler than many year-and-make pages because you do not need to sort by model first just to identify the basic tire size family. What you do need to confirm is which construction style best suits your car and whether your actual wheel width falls within the range for the specific tire you are considering. Checking the wheel before ordering is especially worthwhile on older sports cars that may have been changed over the years.

On a 1960 Morgan, 560-15 is a numeric bias-ply size. The 5.60 portion refers to the tire's nominal section width in the older numeric system, and the 15 identifies the wheel diameter in inches. Unlike a modern metric radial code, it does not use millimeters or a stated aspect ratio. In the 1960 Morgan range, 560-15 appears as a traditional bias-ply option with narrow whitewall and wide whitewall versions from Firestone and US Royal.

That older size format matters because it points you toward a vintage-style tire rather than a modern metric radial. If your Morgan is being restored with a strong emphasis on period presentation, the 560-15 usually aligns more closely with that goal. It is still important to confirm rim width against the exact tire, because some 560-15 versions are centered on a 4.5-inch wheel while others cover a wider 4.50-to-5.50-inch range.

On a 1960 Morgan, 155R15 is a metric radial size. The 155 is the section width in millimeters, the R denotes radial construction, and the 15 is the wheel diameter in inches. In this older Euro-metric style, no aspect ratio is printed, and the format is conventionally treated as an 80-series radial. For 1960 Morgan applications, 155R15 appears in blackwall form from Firestone and Michelin, with examples in T and H speed ratings.

That code tells you that the tire belongs to a later radial sizing language even though it still fits the same 15-inch wheel diameter as the older bias-ply alternative. Many Morgan owners gravitate to this format when they want a tire that looks appropriately narrow but behaves more like a modern radial on real roads. Because tube type and tubeless versions both exist in this size family, the sidewall marking on the exact tire matters before installation.

For a 1960 Morgan, the choice between 155R15 and 560-15 is mainly a choice between radial and bias-ply construction, not wheel diameter. Both sizes fit 15-inch rims and both apply to the 4-4 Series and Plus 4. The 155R15 options are blackwall radials from Firestone and Michelin, while the 560-15 options are bias-ply tires from Firestone and US Royal with narrow whitewall and wide whitewall styling.

Choose 560-15 if the car's appearance and road feel are being kept closer to an early-1960s presentation. Choose 155R15 if you want to stay within the same wheel diameter while moving to a metric radial format that many owners prefer for regular road use. Either way, check the actual wheel width first so the tire's approved rim range matches what is on the car now.

1960 Morgan tire choices include both blackwall and whitewall sidewall treatments, depending on size. The 155R15 radial options come in blackwall form. The 560-15 bias-ply options are available as narrow whitewall and wide whitewall tires. That gives Morgan owners a clear visual split between a restrained radial look and a more decorative bias-ply sidewall treatment.

For many British sports-car restorations, blackwall styling is the cleaner and more typical visual direction, especially if the goal is to preserve a purposeful roadster look. Whitewalls can still appeal to owners building toward a more personalized period presentation, but they change the character of the car noticeably. Sidewall style is worth deciding early, because on a small, narrow-bodied Morgan the tire is a very visible part of the finished stance.

Four brands cover 1960 Morgan applications across the two tire sizes: Firestone, Michelin, and US Royal. In 155R15 radial form, Firestone and Michelin are available. In 560-15 bias-ply form, Firestone and US Royal are available. That split gives the radial and bias-ply choices their own distinct brand mix rather than one brand covering every style.

Brand choice usually follows the kind of Morgan you are building and driving. Some owners start with construction first, then narrow the field by sidewall appearance, tube type, and rim-width compatibility. Others already know they want a Michelin-style radial presentation or an American classic bias-ply look. Either path works as long as the final choice still matches your wheel and the way you expect to use the car.

1960 Morgan tires all mount on 15-inch rims, but the approved wheel width depends on the size and the exact tire. For 155R15 radial tires, the common rim width range is 4.00 to 5.50 inches. For 560-15 bias-ply tires, some products are intended for a 4.5-inch rim, while others cover 4.50 to 5.50 inches. That means the tire size alone is not the whole story when checking wheel compatibility.

Measuring the wheels on the car is the safest next step, especially if the Morgan has had replacement wheels fitted during its life. A 15-inch diameter match does not automatically guarantee the wheel width is ideal for every tire in both size families. Staying within the tire's approved rim-width range helps preserve proper sidewall shape, steering feel, and tread contact without forcing the casing onto an unsuitable wheel.

Inner-tube requirements for 1960 Morgan tires depend on the exact tire you choose. Within the 155R15 radial group, tubeless and tube-type products both exist, so tube status varies by product. One Michelin X appears as TL, while a Michelin XAS appears as TT, and another Michelin XAS-FF appears as TL. The 560-15 bias-ply entries here do not carry TT or TL markings in the size field, so the exact tire specification should be checked before installation.

That variation matters because wheel design and the tire's own construction both influence whether a tube is appropriate. Do not assume that every radial in the same size uses the same setup, and do not treat every older wheel as automatically tubeless-ready. The correct approach is to match the tire's sidewall marking and manufacturer guidance to the wheel actually on the car, especially on a hand-built British sports car with a long service history.

Original-style 1960 Morgan wheels can often be used with both available tire sizes because both 155R15 and 560-15 mount on 15-inch rims. That shared diameter is the key point. The remaining question is wheel width, since the 155R15 radial tires commonly fit 4.00-to-5.50-inch rims, while 560-15 bias-ply tires may call for either a 4.5-inch rim or a 4.50-to-5.50-inch range depending on the product.

In practice, many owners can stay with the same wheel diameter while changing the car's feel and appearance through tire construction alone. The safe move is to verify the wheel width before deciding that every 15-inch option is interchangeable. If your Morgan still wears original wheels, that check is straightforward; if it has replacement wheels, the measurement becomes even more important.

A 1960 Morgan should be stored in a cool, dry, dark place with the tires kept away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing sources. Clean, dry floors are better than damp concrete, and maintaining proper inflation during storage helps the casing hold its shape. Because 1960 Morgan choices include both bias-ply and radial construction, it is worth remembering that bias-ply tires tend to flat-spot more readily during long static periods.

If the car sits for extended periods, move it occasionally or use properly placed stands to reduce the load on one contact patch. That habit helps preserve ride quality and reduces the chance that the first drive of the season begins with temporary thumping or sidewall stress. Collector cars age their tires through time and environment more than mileage, so storage conditions matter almost as much as driving habits.

Tires on a 1960 Morgan are usually judged by age and condition rather than mileage. A collector car can have very low tread wear and still need replacement because the rubber has aged out. As a general rule, begin evaluating older tires carefully once they reach about five to seven years from the DOT date code, and treat ten years as a point where replacement deserves serious consideration even if the tread still looks serviceable.

That age-based approach fits the way most Morgans are used. Weekend drives, storage seasons, and low annual mileage all tend to hide deterioration until you inspect closely. The right habit is to note the date code when the tires are installed and check them periodically for cracking, hardening, uneven wear, and loss of flexibility. A tire can look respectable at a glance and still be past the point where it belongs on a road-driven sports car.

Tires on a 1960 Morgan should be inspected before every drive and again before any longer outing. Look for sidewall cracking, tread separation, embedded objects, unusual wear, cuts, bulges, and pressure loss. On any setup that uses tubes, the valve stems deserve the same attention as the tire itself because stem deterioration can create a sudden air-loss problem even when the casing still appears healthy.

A quick visual check is often enough before a short local drive, but a longer trip calls for a more deliberate inspection and a pressure check when the tires are cold. Older, lightweight sports cars communicate problems early through steering feel and vibration, so changes in behavior should never be ignored. Consistent inspection is one of the simplest ways to protect both the car and the people riding in it.

A 1960 Morgan 4-4 Series would have been associated with bias-ply construction in period, as radial adoption was still far from universal on sports cars of this era and market position. Within the available 1960 Morgan fitments, the most period-oriented choice is the 560-15 bias-ply size, while 155R15 represents a radial alternative in the same 15-inch wheel diameter. Original-equipment branding can vary by market and history, so the construction type and size matter more than chasing a name without supporting provenance.

For a restoration, that means 560-15 is usually the starting point if authenticity is the goal. The exact sidewall treatment you choose should still be weighed against the car's intended presentation, since whitewall styling changes the look significantly on a small British roadster. If your Morgan is being judged seriously, a marque club, factory records source, or model specialist is the best place to confirm market-specific nuances beyond basic size and construction.

Correct tire fitment matters on a 1960 Morgan because judges and knowledgeable enthusiasts notice size, construction, and sidewall treatment quickly. A radial in 155R15 may fit the wheel properly, but it presents a different construction and often a different stance and sidewall behavior than a 560-15 bias-ply. Sidewall style matters too, since blackwall, narrow whitewall, and wide whitewall choices create very different visual impressions on a car with exposed wheels and minimal bodywork.

The practical question is what kind of show standard you are aiming for. A casual local event may accept tasteful deviations, while higher-level originality judging often places more weight on era-correct construction and appearance. Before finalizing a show car, compare your tire choice to period photos, club guidance, and event rules. Tires are one of the most visible finishing details on a Morgan, so getting them right can change the whole presentation.

For a 1960 Morgan in 155R15 form, both the Michelin XAS and Michelin XAS-FF use 155HR15 sizing, blackwall styling, radial construction, 4.00-to-5.50-inch rim compatibility, and an H speed rating. The visible difference in the specification is tube status: the Michelin XAS appears as TT, while the Michelin XAS-FF appears as TL. Both carry the same general dimensional family and sit in the same classic Michelin radial tradition for narrow 15-inch sports-car fitments.

That means the decision is less about broad fitment and more about the wheel and installation approach. If your wheel and setup call for a tube-type tire, the XAS points in that direction; if you are working with a tubeless-compatible arrangement, the XAS-FF may be the more natural fit. On a restoration-minded Morgan, that distinction is important because tube choice affects both authenticity and practical installation.

1960 Morgan tires can be suitable for highway driving when they are in good condition, correctly inflated, and used within the limits of their construction and speed rating. In 155R15 radial form, examples include T-rated tires up to 118 mph and H-rated tires up to 130 mph. The 560-15 bias-ply products shown here do not carry a visible modern speed letter in the size field, so they should be treated with the more conservative mindset normally applied to vintage-style bias-ply tires.

On a 1960 Morgan, the car's age, brakes, suspension, steering geometry, and overall condition often matter as much as the tire itself once speeds rise. A healthy radial setup may feel calmer on modern roads, while a bias-ply setup asks for more period-aware driving habits. Highway use is reasonable when the car is sorted, but a pre-drive inspection and realistic pace are part of the package with any vintage sports car.

Inflation pressure for a 1960 Morgan should be matched to the exact tire you choose and then checked against the vehicle's original guidance. Within the available fitments, 155R15 includes a Firestone radial carrying a 1045-pound load rating at 44 psi, while 560-15 bias-ply options carry 970 pounds at 32 psi. Those figures are tire ratings, not a blanket instruction to inflate every 1960 Morgan tire to the same number.

The best approach is to start with the original owner's manual or marque guidance for vehicle pressure recommendations, then confirm that your chosen tire's rated pressure and load capability are appropriate for that use. Do not transfer a pressure figure from one size or construction type to another just because both fit a 15-inch wheel. Construction, casing behavior, and intended operating range all differ.

Before a longer drive in a 1960 Morgan, inspect each tire for cracks, cuts, bulges, punctures, uneven wear, and any sign of tread or casing separation. Check cold pressure, verify that the spare is usable, and examine the valve stems closely. If your tire setup uses tubes, pay extra attention to stem condition and any slow air loss. The wheels themselves should also be looked over for damage, corrosion, or obvious sealing issues.

That tire inspection should sit alongside a broader mechanical check that suits a 1960 British sports car: fluids, brakes, steering, suspension, and lighting all matter before covering distance. Morgans are simple cars, but they depend on regular attention. A few careful minutes in the garage can catch the sort of age-related issue that would be only an inconvenience in a modern car and a trip-ending problem in an older one.
