1956 MG MG Tires

The 1956 MG MG uses two primary tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both are tied to 15-inch wheels, and both apply to the TD & TF sub-model grouping.

That means the main decision is not wheel diameter but tire type and intended use. A 560-15 keeps the traditional numeric bias-ply format, while 155R15 moves to a classic Euro-metric radial format. Before choosing, confirm the actual wheels on the car, especially if it has been updated over the years, and decide whether vintage appearance or radial driving manners is the higher priority.

The 1956 MG MG uses a 15-inch rim with both of its primary tire sizes. That applies whether the car is running the 560-15 bias-ply fitment or the 155R15 radial fitment.

Rim diameter is only part of the picture, because wheel width still affects which tire is appropriate. Several 155R15 radial options are built around roughly 4.0 to 5.5-inch rim widths, while the 560-15 bias-ply choices vary by product as well. Checking the actual wheel before ordering is especially important on collector cars that may no longer have their original wheel set.

560-15 is a vintage numeric bias-ply 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 1956 MG MG, that size points to a traditional bias-ply fitment rather than a modern metric radial. It is useful for owners who want a period-style look and the classic visual proportions associated with older sports cars. Since numeric bias-ply sizing is less familiar to many modern buyers, it helps to verify wheel width and compare the tire's intended role before mixing it with a radial-based setup.

On the 1956 MG MG, 560-15 is a bias-ply tire size. It uses the older numeric sizing system and is offered in bias-ply construction across several blackwall and whitewall choices.

That matters because a bias-ply tire affects both appearance and driving character differently than a radial. Owners aiming for a traditional presentation often stay with 560-15, while others consider a radial equivalent for a different road feel. If the car has replacement wheels or suspension changes, the exact wheel width and available clearance should still be checked before settling on either construction.

The radial equivalents for 560-15 are 155R15 and 560R15. The 155R15 is an equivalent 80-series metric radial, while 560R15 is a bias-look radial equivalent that keeps a more traditional size presentation.

Each option serves a slightly different goal. A 155R15 follows a Euro-metric radial format, while 560R15 is aimed at owners who want radial construction without moving as far from a vintage visual theme. The recommended rim-width range for these equivalents is 4 to 5 inches, and actual wheel width, overall fit, and clearance should be confirmed before treating either size as an alternative.

That choice depends on how the 1956 MG MG is being used and how closely the owner wants to stay with a traditional setup. The car is associated with both 560-15 bias-ply tires and 155R15 radial tires, so either path can be relevant depending on the wheel and overall build.

Bias-ply tires usually make more sense when period-style appearance is the priority, especially with available whitewall and blackwall treatments in 560-15. Radials are the more modern construction choice and are available in several classic blackwall series in 155R15. Before changing construction, compare wheel width, inspect clearance at steering lock, and make sure the rest of the suspension and alignment are ready for the setup being considered.

Start with the correct primary size and construction for the setup on the car. A 560-15 is the vintage bias-ply route, while 155R15 is the radial route, and both use 15-inch wheels.

After that, compare the details that shape the result: wheel width, sidewall style, brand, tire series, and how the car will actually be driven. A restoration-oriented MG may call for the traditional look of a numeric bias-ply, while a regularly driven car may lead an owner toward a classic radial format. The best choice is the one that matches the car's wheels, appearance goals, and intended road use.

Sidewall style depends on which size and construction you choose. The 155R15 radial options are offered in blackwall form, while the 560-15 bias-ply options include blackwall, narrow whitewall, and wide whitewall treatments.

That creates a meaningful visual decision for a 1956 MG MG owner. Blackwalls usually deliver the most understated sports-car presentation, while whitewalls push the car toward a more decorative mid-century look. Since sidewall treatment changes the car's appearance more than many buyers expect, it helps to choose the style only after the size, construction, and wheel setup have already been confirmed.

The 1956 MG MG has tire options from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Those brands span both 155R15 radial fitments and 560-15 bias-ply fitments.

Brand alone is only one part of the selection process. The better comparison is which brand offers the size, construction, sidewall style, and tire series that match the car's purpose. For example, the radial side centers on classic blackwall choices, while the bias-ply side adds blackwall and whitewall variations. Once the fitment path is chosen, brand differences become easier to evaluate in a useful way.

For a period-style 1956 MG MG, the 560-15 bias-ply size is the most traditional starting point. It uses the vintage numeric format and is available in several blackwall and whitewall presentations that suit a restoration-oriented look.

That does not automatically make every 560-15 the right visual match for every car, because sidewall treatment changes the overall impression considerably. Buyers pursuing strict originality should compare their choice against marque references, period photos, or other vehicle-specific historical material. If the goal is simply a convincing vintage presentation, the key decision is usually blackwall versus the available whitewall widths.

Tire construction affects the look of a restored 1956 MG MG because bias-ply and radial tires present the car differently even when both are built for 15-inch wheels. A 560-15 bias-ply keeps the older sizing language and a more traditional vintage character, while 155R15 reads as a later radial-format choice.

The visual difference becomes even stronger once sidewall style enters the picture. Bias-ply options in this application include blackwall, narrow whitewall, and wide whitewall choices, whereas the radial options stay with blackwall styling. Owners building a driver may accept the radial look easily, but a restoration-focused car usually benefits from deciding appearance first and construction second.

Yes, modifications can affect tire fitment on a 1956 MG MG even when the nominal tire size is correct. Aftermarket wheels, changed wheel width, suspension alterations, ride-height changes, or body modifications can all influence how a 560-15 or 155R15 tire sits on the car.

That is why an owner should inspect the actual wheel and vehicle setup instead of assuming every TD or TF is still configured the same way. Check wheel diameter first, then confirm width, steering clearance, and fender clearance throughout the suspension's travel. Collector cars often carry decades of changes, so the safest approach is to match the tire to the car as it exists now.

Before driving a 1956 MG MG on new tires, inspect the wheels, valve stems, and overall mounting condition, then verify that the tires clear the body and suspension properly. It also helps to look over steering and suspension components so the new tires are not asked to compensate for unrelated wear.

Road readiness on a low-mileage collector car also means checking inflation, watching for early air loss, and rechecking the car after a short initial drive. Vintage vehicles that sit for long periods can hide cracked rubber parts, weak shocks, or alignment problems. A fresh set of tires performs best when the rest of the chassis is equally ready for regular road use.

Collector-car tires on a 1956 MG MG should be inspected regularly for cracking, bulges, cuts, uneven wear, and pressure loss, regardless of whether the car runs 560-15 bias-ply tires or 155R15 radials. Cars that spend long periods parked deserve extra attention because age and storage conditions matter as much as mileage.

Good maintenance also includes keeping the tires properly inflated, moving the car often enough to avoid long-term flat spotting, and storing it away from prolonged sunlight, heat, moisture, and ozone sources. Periodic wheel and alignment checks are worthwhile as well. On an older sports car, tire condition can change slowly and then become serious before the next long drive.
