1962 Morgan Tire Fitment Guide

1962 Morgan vehicles use two tire sizes: 155R15 and 560-15. Both the 1962 Morgan 4-4 Series and the 1962 Morgan Plus 4 use both sizes, and both sizes mount on 15-inch rims. For 155R15, the applicable rim width range appears at 4.00 to 5.50 inches on the products that publish it. For 560-15, published rim widths run from 4.5 inches to 4.50-5.50 inches depending on the tire.

That makes 1962 Morgan fitment simpler than many classic sports cars, because you do not need to sort by model first to find the basic size family. The more important choice is which construction fits your goals. A radial and a bias-ply tire can both be correct at the year-and-make level here, but they deliver a different look and road feel. Confirm the actual wheel width on your car before making the final choice.

On a 1962 Morgan, 560-15 is a numeric bias-ply size. The 5.60 number refers to the tire's nominal section width in inches, while the 15 indicates the rim diameter in inches. This is an older American and British-era sizing convention commonly seen on period-correct reproduction tires for classic sports cars and other collector vehicles from the bias-ply era.

For a Morgan owner, that code matters because it points to a traditional tire construction and period appearance rather than a later metric radial format. In the 560-15 size, Firestone and US Royal options are available, with narrow whitewall and wide whitewall sidewall choices. If your priority is originality in stance, sidewall shape, and vintage driving character, 560-15 is the size family to examine first.

On a 1962 Morgan, 155R15 is a metric radial size. The 155 identifies a nominal section width of 155 millimeters, the R indicates radial construction, and the 15 is the rim diameter in inches. Because no aspect ratio is printed in the size itself, this format is conventionally understood as an 80-series radial in period-style applications such as the Firestone F560 and Michelin X-family tires.

That makes 155R15 easier for modern buyers to recognize, especially if they are more familiar with radial sizing than with older numeric bias-ply codes. For 1962 Morgan use, this size stays on the original 15-inch wheel diameter while offering a radial construction. It is a sensible direction for owners who want a classic-looking tire package but prefer a road manner closer to what later radial-equipped cars deliver.

For a 1962 Morgan, the choice between 155R15 and 560-15 is mainly a choice between radial and bias-ply construction, since both sizes fit 15-inch rims and both apply to the 4-4 Series and Plus 4. The 155R15 options are radial blackwalls from Firestone and Michelin, while the 560-15 options are bias-ply tires from Firestone and US Royal with narrow or wide whitewall styling.

If your Morgan is being restored with strong attention to period feel and presentation, the 560-15 bias-ply route usually aligns better with that goal. If your car is driven more regularly and you want to stay with a classic 15-inch fitment while using radial construction, 155R15 is the more natural choice. The right answer depends less on model and more on whether authenticity or day-to-day driving character comes first.

1962 Morgan tire choices include more than one sidewall treatment. The 155R15 radial options come in blackwall form, while the 560-15 bias-ply options are available as narrow whitewall and wide whitewall tires. That gives Morgan owners a clear visual distinction between the radial and bias-ply paths, not just a difference in construction under the tread and carcass.

On a British sports car of this era, blackwall is usually the more understated and more broadly authentic look, especially for owners pursuing a restrained factory-style presentation. Whitewalls can still appeal to buyers who want a more customized period flavor or a specific show look, but they change the car's visual character more noticeably. If appearance matters as much as fitment, choose the sidewall style before narrowing down to a specific tire series.

1962 Morgan tire coverage comes from Firestone, Michelin, and US Royal. In 155R15, Firestone and Michelin both offer radial choices. In 560-15, Firestone and US Royal offer bias-ply choices. That spread gives Morgan owners access to both traditional bias-ply styling and classic radial options without moving away from the correct 15-inch rim diameter.

Brand selection matters because each brand family tends to emphasize a slightly different combination of appearance, construction, and period character. Michelin's X and XAS lines speak directly to European radial history, while Firestone and US Royal bias-ply offerings support a more traditional vintage presentation. A good way to narrow the field is to decide on construction first, then sidewall style, and then compare the available series inside that size.

1962 Morgan tires mount on 15-inch rims, but the usable rim width depends on the tire size and, in some cases, the specific product. For 155R15, published rim widths run from 4.00 to 5.50 inches on the tires that include that information. For 560-15, some tires specify a 4.5-inch rim while others allow a 4.50 to 5.50-inch range.

That means wheel diameter alone is not enough to confirm the best match. A Morgan owner should verify the actual wheel width on the car before choosing between the radial and bias-ply sizes, especially if the wheels are not original or have been changed during restoration. Staying within the tire maker's published rim-width range helps preserve the tire's intended shape, response, and load behavior.

Inner-tube requirements for 1962 Morgan tires depend on the exact radial product you choose. In 155R15, Michelin X appears as a tubeless TL tire, Michelin XAS appears as a tube-type TT tire, and Michelin XAS-FF appears as a tubeless TL tire, so tube use varies by product within that size. The 560-15 bias-ply options here do not carry TT or TL markings in the size description shown with the product names.

That makes it important to check the actual sidewall marking and the wheel design before installation rather than assuming every tire in the same nominal size uses the same setup. Wire wheels, older rim contours, and restoration-era wheel work can also affect tube decisions on a classic British car. When in doubt, confirm the exact tire's tube designation and the wheel's suitability together instead of treating tube fitment as a size-only question.

Both tire sizes used on 1962 Morgan models are built for 15-inch rims, so the original wheel diameter is compatible with both 155R15 and 560-15. That shared diameter is why the year-and-make fitment picture is relatively simple. The remaining question is wheel width, since radial and bias-ply products within these sizes have published rim-width recommendations that should be checked against the actual wheel on the car.

For a buyer comparing options, that means the original wheels may often stay in service even when switching from bias-ply to radial construction, but diameter compatibility is not the same thing as full setup compatibility. Verify the wheel width first and inspect the wheel condition at the same time. On a hand-built, long-lived marque like Morgan, it is common to find wheels that have been changed, restored, or mixed over the years.

A 1962 Morgan should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age the sidewalls. Keep the tires properly inflated, avoid prolonged contact with standing moisture, and move the car periodically if it will sit for long stretches. Bias-ply tires tend to flat-spot more readily during storage than radials, so a Morgan on 560-15s benefits from more frequent movement or support stands during long off-seasons.

Good storage habits matter on a lightweight sports car because tire shape and condition have a noticeable effect on how the car feels once it is back on the road. Even a low-mile collector Morgan can age its tires out before it wears them out. If the car spends months parked between drives, include tire pressure, sidewall condition, and floor contact points in your regular storage checklist rather than focusing only on fluids and battery care.

Tires on a 1962 Morgan should usually be judged by age as much as by tread wear. A common collector-car rule is to begin evaluating them closely once they reach about five to seven years of age and to treat around ten years as a strong replacement consideration even if they still look usable. The DOT date code on the tire helps establish age, which matters because classic cars often accumulate miles slowly.

That is especially relevant for a Morgan, since many examples are driven seasonally and stored for long periods. A tire can retain decent tread depth and still become a poor candidate for continued use because of internal aging, hardened rubber, or sidewall cracking. If you have just acquired the car and do not know the tire age, checking the date code should be one of the first steps before any meaningful road use.

Tires on a 1962 Morgan deserve a quick inspection before every drive and a more thorough check before longer outings. Look for sidewall cracking, tread damage, uneven wear, cuts, bulges, and pressure loss. If your Morgan uses a tube-type tire, inspect the valve stem condition carefully as well, since the stem becomes an important part of the air-retention system and can age along with the rest of the assembly.

Frequent inspection is more important on a collector car than many owners expect because age, storage, and intermittent use can reveal problems before mileage does. A short local drive may hide an issue that becomes obvious only when heat builds on a longer trip. Building a simple pre-drive tire check into your routine is one of the easiest ways to avoid roadside trouble and to protect wheels, fenders, and suspension parts from preventable tire failure.

A 1962 Morgan 4-4 Series would have been associated with bias-ply-era fitment practice, even though radial options are available today in a compatible 15-inch size. For this year and make, both 560-15 bias-ply and 155R15 radial options exist, but a buyer pursuing a strongly original presentation would usually begin with the bias-ply size rather than the later-style radial format. Original-equipment branding could vary by market and period, so construction, size, and sidewall appearance matter more than assuming one universal factory brand.

That distinction matters in restoration because a Morgan judged for authenticity is usually evaluated on overall period correctness, not just whether the tire physically fits the wheel. If your goal is concours-level accuracy, confirm the expected tire specification with a Morgan marque club, period road tests, or surviving factory literature for your market. Radials may still be a sensible choice for road use, but they change the car's authenticity profile in a visible way.

Correct tire fitment matters on a 1962 Morgan because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall treatment immediately. A radial blackwall and a bias-ply whitewall can both fit the wheel diameter, but they create very different visual and historical impressions. On a traditionally styled British sports car, an obviously modern-looking tire or an era-inappropriate sidewall treatment can stand out even to casual observers.

For show use, the right choice depends on the event and the standard being applied. Some local shows reward overall presentation more than strict factory accuracy, while marque judging can be far more particular about period-correct construction and appearance. Before committing to a tire for a high-level restoration, check the rules used by the club or event where the car will be shown and match the tire's style to that standard.

For a 1962 Morgan in 155R15 radial sizing, the Michelin XAS and Michelin XAS-FF share the same basic size, 82H speed rating, 15-inch rim diameter, 4.00 to 5.50-inch rim width range, and blackwall presentation. The important setup difference is tube designation: the XAS appears as 155HR15 82H TT, while the XAS-FF appears as 155HR15 82H TL. Both also carry the same published weight in this size.

That means the choice is less about dimensions and more about how the tire is intended to be mounted on the wheel you are using. If your Morgan's wheels and restoration plan call for a tube-type configuration, the XAS has a clearer alignment with that setup. If you are working with a tubeless-compatible wheel arrangement and want the same size and speed class, the XAS-FF may be the better fit.

1962 Morgan tires can be suitable for highway driving when the tire's construction, condition, and speed rating match the way the car is used. In the 155R15 radial size, Michelin X carries a T rating to 118 mph and Michelin XAS and XAS-FF carry an H rating to 130 mph. The 560-15 bias-ply products shown here do not carry speed letters in their size descriptions, so they should be treated with the expectations appropriate to a traditional bias-ply collector tire rather than as a modern high-speed radial.

In real use, the tire is only one part of the highway equation on a 1962 sports car. Brakes, steering, suspension condition, wheel alignment, and the overall age of the vehicle can matter just as much as the tire's speed capability. A sound radial setup can make a Morgan feel more at ease in modern traffic, but any collector car should still be driven within the limits of its chassis, weather conditions, and mechanical state.

Inflation pressure for a 1962 Morgan should start with the vehicle maker's recommendation for the car and then be checked against the tire's own published limits. In 155R15, one radial option carries a maximum load of 1045 pounds at 44 psi. In 560-15, the bias-ply options that publish load figures carry 970 pounds at 32 psi. Those numbers are maximum load-and-pressure pairings for the tire, not automatic day-to-day running pressures for every Morgan.

The safest approach is to use the Morgan factory guidance as your baseline and then confirm that the tire you choose is being used within its rated capacity. Do not transfer a pressure figure from the radial size to the bias-ply size, or vice versa, just because both fit 15-inch wheels. Construction type, vehicle setup, and tire design all affect how inflation should be approached on a classic car.

Before a longer drive in a 1962 Morgan, inspect all five tires if the car carries a spare. Check for cracking, cuts, bulges, irregular wear, and any signs of impact damage. Confirm cold inflation pressures, look at valve stem condition, and make sure the spare is serviceable rather than simply present. On a car using a tube-type tire, valve stem integrity deserves extra attention because a stem problem can end the trip quickly.

A tire check should be part of a wider pre-drive routine on an older Morgan rather than a stand-alone task. Wheel fastener security, brake feel, fluid levels, steering play, and lighting all deserve the same careful attention before sustained road use. Classic sports cars reward preparation, and the time spent checking the tires and the rest of the car usually pays off with a more relaxed and safer drive.
