1965 Morgan 4-4 Series Tires

The 1965 Morgan 4-4 Series uses two primary tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both sizes are built for 15-inch wheels, so the main fitment question is not wheel diameter but which construction and sizing system matches the car’s current setup and the owner’s goals.

A 560-15 keeps the car in a vintage numeric bias-ply format, while 155R15 uses a classic Euro-metric radial format. Owners choosing between them should confirm the actual wheel width on the car, compare the overall look they want, and make sure any construction change still works with the vehicle’s clearance and intended road use.

The 1965 Morgan 4-4 Series uses a 15-inch rim diameter with both of its primary tire sizes. That applies to the 560-15 bias-ply fitment and the 155R15 radial fitment, so the diameter stays the same even though the sizing system and construction type change.

Rim diameter is only part of the fitment picture on a narrow-tire sports car like this. Before selecting a tire, it is still important to check the actual wheel width, especially if the car has replacement wheels or has been altered over the years, because a correct 15-inch diameter alone does not settle full tire compatibility.

Yes. The 1965 Morgan 4-4 Series Base follows the same fitment pattern as the model overall, using either 560-15 bias-ply tires or 155R15 radial tires on 15-inch wheels. There is not a separate sub-model-only tire size to sort through on this page.

That simplifies the search, but the decision still matters because the two sizes represent different constructions and a different visual character. A buyer should look at the wheels currently on the car, decide whether a period-style bias-ply look or a classic radial setup is the goal, and verify that the selected tire matches the car’s present configuration.

560-15 is the bias-ply tire size for the 1965 Morgan 4-4 Series. It uses the older numeric sizing format, with the first number expressing nominal section width in inches and the final number identifying the 15-inch rim diameter.

That makes 560-15 the traditional choice for owners who want a more vintage tire profile and period-style appearance. Radial alternatives do exist, but moving away from bias-ply construction should involve checking wheel width, overall dimensions, and clearance so the car’s setup still suits the tire selected.

Radial equivalents for 560-15 include 155R15 and 560R15. The 155R15 option is an 80-series metric radial equivalent, while 560R15 is a bias-look radial equivalent that keeps a more traditional visual style while using radial construction.

These options give a 1965 Morgan 4-4 Series owner two distinct ways to move from bias-ply toward radial construction. A recommended rim-width range of 4 to 5 inches applies here, and the right next step is to compare the tire choice against the car’s actual wheel width, body clearance, and intended use rather than treating the equivalent as automatic interchangeability.

Start by confirming the wheel diameter and width, then compare the intended radial size with the car’s current tire setup. For a 560-15 fitment, the available radial-equivalent paths are 155R15 and 560R15, and both need to be evaluated as alternatives rather than assumed replacements.

A narrow British sports car can be sensitive to wheel and tire changes, so steering clearance, fender clearance, and suspension condition deserve attention before the switch. It also helps to decide whether the goal is a more traditional appearance or a classic radial presentation, since that choice often points the buyer toward a bias-look radial or a Euro-metric radial.

A 560-15 tire for a 1965 Morgan 4-4 Series should first match the car’s intended bias-ply setup and 15-inch wheel diameter. After that, the main selection factors are sidewall style, brand, rim-width suitability, and whether the car is being kept in a traditional road-going presentation or used in a more specialized way.

Available 560-15 choices include blackwall, narrow whitewall, and wide whitewall designs from Firestone, US Royal, and Coker Classic, along with a Pro-Trac front runner option. Matching the visual style to the car matters, but so does confirming that the wheel width and the way the car is driven line up with the exact tire being considered.

The available sidewall styles for the 1965 Morgan 4-4 Series include blackwall, narrow whitewall, and wide whitewall. Blackwall appears across both radial and bias-ply offerings, while the whitewall choices are found in the 560-15 bias-ply size.

That means sidewall style is part of the decision once the correct size and construction have been chosen. A buyer focused on a simple sporting look may lean toward blackwalls, while a restoration-oriented owner may want one of the whitewall treatments, but the final choice still needs to stay within the correct tire size and wheel specifications.

Tires for the 1965 Morgan 4-4 Series are available from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Those brands cover both primary fitment paths, with radial choices centered on 155R15 and bias-ply choices centered on 560-15.

Brand is only one part of the comparison. It is more useful to narrow the search by correct size and construction first, then compare tire series, sidewall style, rim-width specifications, and the kind of appearance or road use the car is being built around rather than choosing a tire by brand name alone.

For a period-style 1965 Morgan 4-4 Series, the 560-15 bias-ply size is the natural starting point because it keeps the car in a vintage numeric size and traditional construction. That route also opens up blackwall, narrow whitewall, and wide whitewall choices, depending on the look the owner wants.

A radial such as 155R15 can still suit a classic presentation, especially on a driver-focused car, but it changes the construction and sizing convention. When exact originality matters, the safest approach is to compare the tire decision with marque-specific references, restoration photos, and the car’s own history before settling on a sidewall style or construction.

Tire construction changes more than ride and handling on a restored 1965 Morgan 4-4 Series; it also affects the car’s visual character. A 560-15 bias-ply keeps a distinctly vintage look, while a 155R15 radial presents the car in a more modernized classic-tire format even though both remain narrow 15-inch fitments.

That difference becomes especially noticeable when paired with sidewall styling. Whitewall bias-ply tires can emphasize a more traditional restoration-oriented presentation, while blackwall radials tend to give a cleaner touring appearance. The right choice depends on whether the car is being finished as a period-style display piece, a road car, or a blend of both.

Yes. Modifications can change tire fitment on a 1965 Morgan 4-4 Series even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, suspension alterations, bodywork changes, or steering-component differences can all affect how a 560-15 or 155R15 tire sits and clears.

That matters most when a car has changed hands several times or has been rebuilt over many years. Before selecting tires, inspect the actual wheels on the car and check for rubbing at full steering lock and through suspension movement, especially if the car no longer sits at original ride height or uses replacement chassis components.

Before driving a 1965 Morgan 4-4 Series on new tires, inspect the wheels for correct diameter and sound condition, verify that the tires are seated properly, and confirm inflation pressure for the selected tire. A quick look at valve stems, lug security, and visible clearance around fenders and steering components is also worthwhile.

A collector-era car should also be checked beyond the tires themselves. Suspension bushings, steering play, brake condition, and wheel-bearing health can influence how the car behaves once fresh rubber is installed, so a short low-speed road test followed by another visual inspection is a smart way to catch issues before a longer outing.

Collector-car tires on a 1965 Morgan 4-4 Series should be inspected regularly for air loss, tread wear, sidewall cracking, cuts, bulges, and signs of age. Both 560-15 bias-ply tires and 155R15 radials benefit from proper inflation, clean storage conditions, and periodic movement so the car does not sit in one spot for long periods.

Storage habits matter almost as much as mileage on a lightly used Morgan. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and checking them before each drive is wise because collector vehicles often age out their tires before they wear them out through normal road use.
