1952 MG MGA Tires

The 1952 MG MGA uses two recognized tire sizes: 560-15 in a bias-ply construction and 155R15 in a radial construction. Both are 15-inch fitments, so the main distinction is not wheel diameter but the type of tire and the sizing system used. That gives owners a traditional vintage bias-ply option as well as a classic radial option.

Choosing between them starts with the wheel already on the car and the result you want from it. A 560-15 keeps the period-style bias-ply look, while 155R15 follows a Euro-metric radial format. If the car has been changed over the years, verify actual wheel width and available clearance before settling on one path.

The primary tire fitments for a 1952 MG MGA use a 15-inch rim diameter. That applies to both the 560-15 bias-ply size and the 155R15 radial size, so either fitment path stays within the same basic wheel diameter. The difference between the two is the tire construction and sizing convention rather than a change in rim diameter.

Rim width still matters even when the diameter is correct. Several of the applicable products call for wheel widths in the 4-inch to 5.5-inch range, depending on the tire. A 15-inch wheel alone does not confirm suitability, so it is worth measuring the wheel and checking clearance if the car has non-original wheels or suspension changes.

560-15 is a vintage numeric bias-ply tire size. The 560 refers to an approximate 5.60-inch nominal section width, and the 15 refers to the wheel diameter in inches. On a 1952 MG MGA, that size points to a traditional bias-ply fitment with the shape and visual character many restoration-oriented owners want from an early British sports car.

Understanding that code helps separate size from construction. It does not mean the same thing as a modern metric radial size, even though both may mount on a 15-inch wheel. If the goal is to move from bias-ply to radial, compare the available radial equivalent carefully rather than assuming any 15-inch tire in a similar width range will suit the car.

On the 1952 MG MGA, 560-15 is a bias-ply tire size. It uses the older numeric sizing system and is offered here in traditional bias-ply constructions from brands such as Firestone, US Royal, and Coker Classic. That makes it the vintage-style choice for owners who want the car to retain an earlier tire profile and sidewall presentation.

The practical difference is that a bias-ply tire is not just a styling choice; it also sets the car on a different construction type than a radial. Before selecting 560-15, confirm that the wheel width suits the specific tire chosen and decide whether period-style appearance matters more than moving to a radial alternative such as 155R15 or 560R15.

Two radial-equivalent sizes are available for 560-15. The first is 155R15, which is an 80-series metric radial equivalent. The second is 560R15, a bias-look radial equivalent intended to preserve a more traditional visual impression while changing to radial construction. Those are the meaningful radial alternatives tied directly to the original 560-15 size.

Each option should be treated as an alternative rather than an automatic replacement. The recommended rim-width range for the equivalent fitment is 4 to 5 inches, and it is wise to compare the car's actual wheels, fender clearance, and suspension condition before converting. That is especially important on older sports cars that may have been altered over time.

That choice depends on how the 1952 MG MGA is being used and how closely the owner wants to stay with a traditional presentation. A 560-15 bias-ply tire keeps the older construction and vintage look, while 155R15 brings the car into a classic radial format on the same 15-inch rim diameter. Both are legitimate fitment directions for this car.

The next step is matching the tire to the car's actual setup and purpose. A restoration-oriented car may lean toward bias-ply, while a driver focused on radial construction may prefer 155R15 or a bias-look radial route. Wheel width, clearance, and the effect of any prior modifications deserve a careful check before making the switch.

Start with the construction you want on the car. The 1952 MG MGA can use 560-15 bias-ply tires or 155R15 radial tires, and that choice affects the look of the car as much as the fitment path. After that, compare the available tire series, sidewall presentation, and the wheel-width requirements attached to the specific tire you are considering.

A buyer with restoration goals may focus first on bias-ply appearance, while a road-use buyer may begin with radial construction. It also helps to compare load figures where they are stated, such as 970@32 psi on several 560-15 bias-ply options or 1045@44 psi on the Firestone 155R15 radial, without treating those values as a vehicle requirement.

The 1952 MG MGA has several sidewall treatments available across its applicable tire sizes. In 560-15 bias-ply, choices include blackwall, narrow whitewall, and wide whitewall. In 155R15 radial, the available products are blackwall tires. That makes sidewall appearance one of the clearest visual differences when comparing tires for this car.

Sidewall style should be chosen around the look you want rather than assumed originality. Blackwalls usually keep the presentation simple and sporting, while the whitewall options move the car toward a more stylized period appearance. If appearance matters as much as fitment, compare sidewall treatment alongside construction so the finished stance and visual balance make sense.

Tires for the 1952 MG MGA are available from several brands, including Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Brand variety is split across the two size paths, with Michelin, Avon, and Vredestein appearing in 155R15 radial fitments, while Firestone, US Royal, Coker Classic, and Pro-Trac appear in 560-15 bias-ply fitments.

The useful comparison is not simply brand name but what each brand offers within the correct size. Some options emphasize a traditional bias-ply look with blackwall or whitewall styling, while others focus on classic radial formats and series differences. Once the correct size and construction are settled, brand becomes part of the narrower comparison among appearance and wheel compatibility.

For a period-style 1952 MG MGA, 560-15 is the natural starting point because it is the vintage numeric bias-ply size used on this application. That size is available in blackwall, narrow whitewall, and wide whitewall forms, giving the car a traditional early postwar tire presentation. It is the more appearance-led choice when authenticity of look matters.

The exact sidewall and brand should still be chosen carefully. Period-style does not automatically mean one whitewall width or one tire line is correct for every restored car. When exact originality is important, compare the tire choice against marque references, period photos, or vehicle-specific restoration guidance, then confirm that the selected tire also suits the wheel width on the car.

Tire construction changes the visual character of a restored 1952 MG MGA more than many owners expect. A 560-15 bias-ply tire gives the car a distinctly vintage look tied to older sizing practice and sidewall styling, while a 155R15 radial has a more modern construction format even though it still fits a 15-inch rim and remains visually appropriate for many classic drivers.

That difference matters most when the car is being finished to a specific restoration theme. A bias-ply setup usually supports a more traditional presentation, while a radial setup can shift the look slightly toward practical road use. Sidewall treatment then fine-tunes the result, especially when comparing blackwall against narrow or wide whitewall bias-ply options.

Yes, modifications can affect tire fitment on a 1952 MG MGA even when the nominal tire size is correct. Aftermarket wheels, altered wheel width, suspension changes, ride-height changes, or bodywork repairs can all change the space available around the tire. That matters whether the car is running 560-15 bias-ply tires or 155R15 radials on a 15-inch rim.

The safest approach is to treat the car in front of you as the final authority. Measure the actual wheel, inspect steering and fender clearance, and look for any signs of rubbing through the full range of motion. An older sports car that has been rebuilt over decades may not match its original wheel and suspension setup exactly.

Before road use, inspect the wheel condition, confirm the tire size and construction match the intended setup, and check that each tire is seated properly and inflated correctly for the tire being used. It is also smart to examine valve stems, wheel hardware, and the surrounding suspension and steering components, especially on a collector car that may sit for long periods.

A short test drive should be approached as a verification step rather than a routine outing. Listen for rubbing, watch for pull or vibration, and recheck air pressure after the first miles. On an older MG, it also pays to inspect for sidewall contact at full steering lock and to confirm there is no interference once the car is loaded and moving.

Collector-car tire maintenance begins with regular pressure checks, visual inspections, and attention to age and storage conditions. Whether the 1952 MG MGA is running 560-15 bias-ply tires or 155R15 radials, the tires should be checked for cracks, cuts, bulges, uneven wear, and slow air loss. Cars that are driven infrequently deserve closer inspection because tire condition can change even with low mileage.

Storage habits matter almost as much as road miles. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources, and inspect the tires before each outing rather than assuming they are fine because the tread still looks good. A collector MG that sits for weeks or months benefits from consistent pressure maintenance and periodic movement.
