1951 MG Tires

The 1951 MG uses two tire sizes on a 15-inch rim: 560-15 in bias-ply construction and 155R15 in radial construction. For the covered TD and TF application, those are the relevant fitment paths, so the size decision is tied closely to the type of tire construction you want on the car.

That means the first question is not wheel diameter, since both sizes are built for a 15-inch rim. The practical decision is whether to stay with the traditional numeric bias-ply format or move to the Euro-metric radial size, then confirm the actual wheel width and clearance on the car before final selection.

The applicable tire sizes for a 1951 MG use a 15-inch rim diameter. Both the 560-15 bias-ply fitment and the 155R15 radial fitment are built around that same 15-inch wheel size, which keeps the rim-diameter question simple for this application.

Rim diameter is only part of the fitment picture, especially when comparing bias-ply and radial tires. It is still important to confirm the wheel width on the car, since the available products in these sizes call for different rim-width ranges depending on the tire and construction being considered.

Yes. The covered 1951 MG TD & TF application shares the same two tire-size choices: 560-15 in bias-ply form and 155R15 in radial form. That keeps fitment straightforward across the listed sub-model rather than splitting the car into different wheel-diameter or sub-model-only tire sizes.

Because the size choices are shared, selection becomes more about the kind of driving and appearance you want. A period-style restoration often points buyers toward the bias-ply size, while a road-driven car may lead them to evaluate the radial option after checking the wheel setup already on the vehicle.

On a 1951 MG, 560-15 is the bias-ply tire size. It uses the older numeric sizing system, where the leading number represents an approximate section width rather than a modern metric measurement, and it is the traditional construction choice for this 15-inch fitment.

That matters because bias-ply selection is usually tied as much to appearance and period feel as it is to size alone. Buyers looking at 560-15 can compare blackwall, narrow whitewall, and wide whitewall options, while anyone considering a move away from bias-ply should verify wheel width and fitment before changing construction.

The radial equivalents for 560-15 are 155R15 and 560R15. The 155R15 size is the 80-series metric radial equivalent, while 560R15 is the bias-look radial equivalent for buyers who want a more traditional visual presentation while moving to radial construction.

Those options share the same general 15-inch fitment family, but they should still be treated as alternatives rather than automatic replacements. The recommended rim-width range for the equivalency is 4 to 5 inches, and the final choice should be checked against the wheel, tire dimensions, and clearance around the car.

A 1951 MG owner moving from 560-15 bias-ply tires to a radial alternative should first confirm the wheel diameter and actual wheel width, then compare the intended radial size with the car's available space. For this application, 155R15 and 560R15 are the relevant radial-equivalent directions to consider.

The important follow-up is checking the car as it sits today rather than assuming every MG remains unchanged. Tire clearance at the fenders and steering, wheel condition, suspension wear, and any previous wheel or chassis modifications can all affect whether a radial alternative is the right choice for the vehicle.

Start with the correct size and construction for the kind of car you want to maintain. On a 1951 MG, that means deciding between the traditional 560-15 bias-ply format and the 155R15 radial format, then comparing individual tires by brand, sidewall style, tire series, load specification, and wheel-width suitability.

A restoration-oriented car may lean toward the bias-ply size for its period-style look, while a car intended for more frequent road use may point toward the radial option. Once that direction is clear, compare the product details carefully so the tire matches both the car's wheels and the way the vehicle will actually be driven.

The sidewall choices for a 1951 MG depend on the tire size and construction you choose. In 560-15 bias-ply form, available styles include blackwall, narrow whitewall, and wide whitewall. In 155R15 radial form, the available products are blackwall tires.

That makes sidewall choice an important part of the buying decision, especially on a small British sports car where the tire is highly visible. A whitewall can create a more decorative vintage presentation, while a blackwall usually gives the car a cleaner sporting look closer to what many MG owners prefer.

Tires for the 1951 MG are available from several brands depending on size and construction. The 155R15 radial selection includes Firestone, Michelin, Avon, and Vredestein, while the 560-15 bias-ply selection includes Firestone, US Royal, Coker Classic, and Pro-Trac.

Brand choice should be considered alongside the tire's series, sidewall treatment, and construction type rather than as a standalone decision. A buyer comparing products for this MG is really balancing the intended look of the car, the wheel-width requirements of the tire, and whether the car is staying bias-ply or moving toward radial construction.

For a period-style 1951 MG, the 560-15 bias-ply size is the natural starting point because it preserves the vintage numeric sizing format and the traditional construction associated with cars of this era. Within that size, buyers can choose blackwall, narrow whitewall, or wide whitewall presentations depending on the look they want.

The best appearance choice depends on how closely the car is being restored and what historical reference is guiding the project. When exact originality matters, marque-club guidance, period photographs, and vehicle-specific restoration references are worth checking before settling on a particular sidewall style or brand presentation.

Tire construction changes the overall character of a restored 1951 MG as much as the size itself. A 560-15 bias-ply tire gives the car a more traditional early-1950s presentation, while a 155R15 radial introduces a more modern tire profile and labeling style even though it remains on the same 15-inch rim diameter.

That visual difference matters on an MG because the wheels and tire sidewalls are a noticeable part of the car's stance. Buyers trying to preserve a restoration-oriented look often start with the bias-ply route, while those wanting radial construction may prefer a more understated blackwall presentation to keep the car visually coherent.

Yes. Even though the 1951 MG uses 15-inch tire sizes, modifications can still change what works on the car. Aftermarket wheels, altered wheel widths, suspension changes, brake conversions, and body or fender adjustments can all affect clearance and may influence whether a 560-15 bias-ply or 155R15 radial choice remains appropriate.

That is why the car should be checked in its current condition rather than judged only by model-year fitment. Measure the installed wheels, inspect steering and fender clearance through full travel, and confirm there is no interference before choosing a different construction or equivalent-style tire for road use.

Before driving a 1951 MG on new tires, inspect the wheels, valve stems, and the general condition of the suspension and steering components. The tires themselves should be checked for proper inflation, correct seating on the rim, and adequate clearance around the fenders, chassis, and steering range once installed.

Older collector cars benefit from a broader walk-around before the first drive. Look for fluid leaks that could reach the tires, confirm lug hardware is secure, and recheck pressure after the car has sat. A short, careful test drive followed by another inspection is a smart way to catch early fitment issues.

Collector-car tires on a 1951 MG should be maintained with regular pressure checks, visual inspections, and attention to age as well as tread. Whether the car runs 560-15 bias-ply tires or 155R15 radials, watch for cracking, bulges, cuts, uneven wear, and slow air loss, especially if the car is driven infrequently.

Storage conditions matter almost as much as mileage on a low-use MG. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires, and periodic movement of the vehicle helps avoid long stationary loads in one spot on the casing.
