1951 MG MGA Tires

The 1951 MG MGA uses two 15-inch tire sizes: 560-15 in a bias-ply format and 155R15 in a radial format. Those sizes represent two different approaches to the car rather than two different wheel diameters, so the main fitment question is which construction the car is set up to use.

That means the right selection starts with confirming the wheel and the intended tire type. A buyer keeping a period-style presentation will usually focus on 560-15 bias-ply options, while someone considering a radial setup will look at 155R15 and compare wheel width, tire dimensions, and clearance before making the change.

The tire sizes associated with the 1951 MG MGA both use a 15-inch rim diameter. That applies to the 560-15 bias-ply size and to the 155R15 radial size, so wheel diameter itself is not the dividing line between the two fitment paths.

The more important check is wheel width and overall compatibility with the tire you want to run. A 15-inch rim can still vary in width, and that matters when comparing a traditional bias-ply setup with a radial alternative, especially on a small British sports car where clearance and steering room are worth confirming carefully.

Yes. The covered 1951 MG MGA 1600 uses the same tire-size choices associated with this vehicle, including both the 560-15 bias-ply size and the 155R15 radial size. There is no separate sub-model-specific rim diameter to sort out first.

That keeps the decision centered on how the car is being equipped rather than on trim-level differences. The practical next step is deciding whether the goal is a more traditional bias-ply look or a radial-format tire, then checking the actual wheels on the car in case it has been changed from its earlier setup.

On the 1951 MG MGA, 560-15 is the bias-ply tire size. It is the traditional numeric vintage format for this car and is offered in classic bias-ply construction with blackwall, narrow whitewall, and wide whitewall styling depending on the tire chosen.

That matters because a bias-ply tire changes both the visual character and the setup decision. Choosing 560-15 usually points toward a more period-style presentation, while moving away from it toward a radial calls for checking wheel width, overall tire dimensions, and vehicle clearance rather than assuming every 15-inch wheel arrangement behaves the same.

For a 1951 MG MGA running the original 560-15 size, the radial equivalents are 155R15 and 560R15. The 155R15 is the 80-series metric radial equivalent, while 560R15 is the bias-look radial equivalent for buyers who want a radial construction with a more traditional appearance.

Those two options solve different problems, so neither should be treated as automatic interchangeability. The recommended rim-width range for the equivalent setup is 4 to 5 inches, and the right choice still depends on the wheel on the car, the available space around the suspension and fenders, and the appearance the owner wants.

That depends on what matters most for the car. A 560-15 bias-ply tire keeps the vintage sizing format and gives the MG a more traditional presentation, while a 155R15 radial moves the car into a classic Euro-metric radial format on the same 15-inch wheel diameter.

The better choice is the one that matches the car's purpose and setup. A restoration-oriented owner may prefer the bias-ply look and sidewall choices, while a road-use oriented owner may want to evaluate a radial alternative. Either way, the actual wheel width, tire clearance, and any previous modifications deserve a careful check first.

Start with the basic question of construction. The 1951 MG MGA can be equipped with a 560-15 bias-ply tire or a 155R15 radial, and that choice shapes everything else, including sidewall appearance, tire series, and the kind of driving character the owner is trying to preserve.

After size and construction, compare the details that actually separate the options: wheel-width suitability, sidewall style, brand, tire series, and any load information supplied with the tire. On a compact sports car, it also makes sense to look closely at the wheels currently installed, since an older MG may no longer be wearing its earlier setup.

Sidewall styling depends on the size and construction you choose. In 560-15 bias-ply, the available presentations include blackwall, narrow whitewall, and wide whitewall. In 155R15 radial, the available products stay in a blackwall format across the current classic radial selections.

That makes sidewall choice a major part of the buying decision, especially if the car is being restored or styled to a particular era. A blackwall tire keeps the presentation more restrained, while whitewall versions create a more decorative vintage look. The key is choosing a sidewall treatment that suits the car's appearance without losing sight of fitment.

The 1951 MG MGA has tire options from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Brand availability varies by size, with the radial 155R15 selection centered on Firestone, Michelin, Avon, and Vredestein, while the 560-15 bias-ply choices include Firestone, US Royal, Coker Classic, and Pro-Trac.

Brand alone is only part of the decision. It helps to compare the construction, tire series, sidewall treatment, and wheel-width compatibility that come with each offering. A buyer choosing among brands for an MG usually gets the clearest result by narrowing the correct size and visual style first, then comparing the individual tire specifications.

For a period-style presentation, the 560-15 bias-ply tire is the natural starting point on a 1951 MG MGA. It keeps the vintage numeric sizing format and is available in several classic visual treatments, including blackwall, narrow whitewall, and wide whitewall, depending on the look the car is meant to carry.

That does not automatically make every 560-15 tire historically exact for every restoration goal. Buyers chasing a highly specific result should compare brand, sidewall treatment, and overall presentation against marque references and vehicle-specific history, while buyers focused more on vintage character can use the bias-ply format itself as the guiding choice.

Tire construction changes the visual impression of the 1951 MG MGA almost as much as it changes the fitment path. A 560-15 bias-ply tire gives the car a more traditional vintage profile, while a 155R15 radial introduces a later Euro-metric look with modern radial construction and blackwall-only product choices in this size range.

That difference matters on a restored sports car where stance and sidewall style are part of the finished presentation. Someone building for road use may still choose a radial, but an owner who wants the car to read more like an early postwar British sports machine will usually examine the bias-ply option first and then refine the sidewall choice.

Yes. Even though the 1951 MG MGA uses 15-inch tire sizes, changes to the wheels, suspension, ride height, or bodywork can alter which tire works properly on the car. That is especially important when moving between the 560-15 bias-ply fitment and a 155R15 radial arrangement.

A modified car should be checked as it sits rather than treated like a completely stock example. Wheel width, offset, steering clearance, and fender room can all influence the final result, and those checks become more important when the car has aftermarket wheels, suspension changes, or other alterations made during restoration or long-term ownership.

Before driving a 1951 MG MGA on new tires, inspect the wheels, valve stems, and the overall tire seating on the rim. It also makes sense to verify that the tire size on the car matches the intended setup, then look over the suspension and steering for obvious looseness or wear that could affect how the car tracks.

A short clearance check is equally important. Turn the steering from lock to lock, confirm there is no contact at the fenders or suspension points, and set the tires to the pressure appropriate for the tire being used. After the first few drives, recheck inflation and look for any signs of rubbing or uneven behavior.

Collector-car tires on a 1951 MG MGA should be inspected regularly even if the car is driven only occasionally. Check for cracking, cuts, bulges, irregular wear, and slow air loss, and keep an eye on overall condition rather than focusing only on tread depth, since low-use vintage cars can age out tires before wearing them out.

Good storage habits help as much as routine inspections. Keep the car away from prolonged sunlight, heat, moisture, and ozone-producing equipment when possible, and maintain the correct pressure for the tire being used so the casing is not stressed in storage. Before a longer drive, confirm inflation again and give each tire a close visual check.
