The 1974 MG Midget belongs to the final stretch of a long-running British sports car formula built around light weight, simple mechanicals, and direct road feel. By this point, the Midget remained a compact open-top driver’s car whose proportions and handling character are closely tied to its tire size. The 1974 MG Midget uses a 145R13 radial on a 13-inch rim, so the main decision is less about multiple fitments and more about choosing the right radial within that original-size framework. Blackwall options from Michelin and Firestone keep the presentation traditional while letting owners balance period-style appearance, intended road use, and wheel compatibility.
Which Tire Size Is Right for The 1974 MG Midget
The 1974 MG Midget uses one primary tire size: 145R13. It is a radial fitment on a 13-inch rim, and the same size applies to the Base sub-model, so the key choice is selecting the right tire within that size rather than sorting through multiple factory fitments. For most owners, that means comparing tire series, brand character, and wheel-width compatibility before making a final decision.
A 145R13 size uses a nominal section width of 145 millimeters, radial construction, and a 13-inch rim diameter. In this format, the aspect ratio is not written into the size code, and it is commonly treated as an 80-series style radial. On a 1974 MG Midget, this size preserves the car’s small-scale tire proportions while giving owners a correct-format radial choice. Available options include Michelin and Firestone blackwall tires in distinct series, so the decision often comes down to the tire’s period-style character, rim-width suitability, and how closely the finished look matches the car’s intended presentation.
Tire fitment is straightforward across the covered 1974 MG Midget sub-models. The Base version uses the same 145R13 radial size, so the focus stays on tire selection within that fitment rather than sorting out different wheel diameters or alternate primary sizes.

These FAQs focus on the 1974 MG Midget’s 145R13 fitment, 13-inch rim requirements, available radial tire choices, and the practical checks that matter before regular road use or a restoration-minded replacement.
Tire Size & Fitment
What tire size fits a 1974 MG Midget?
The 1974 MG Midget uses a 145R13 radial tire. That size combines a 145-millimeter nominal section width with radial construction and a 13-inch rim diameter, which suits the Midget’s compact proportions and keeps the tire choice within the correct original-size format for this model year.
Because there is only one primary size here, the real decision is which 145R13 tire best matches the car’s needs and wheels. It helps to confirm that the car still has 13-inch wheels in an appropriate width range and has not been changed to aftermarket wheels or a different tire package over the years.
What size rim does a 1974 MG Midget use?
A 1974 MG Midget uses a 13-inch rim with its 145R13 tire size. That rim diameter is the key fitment point because the tire’s final number, 13, refers directly to the wheel diameter the tire is built to mount on.
Rim diameter should be confirmed before ordering tires, especially on older sports cars that may have seen wheel changes during restoration or routine ownership. One available 145R13 product is intended for a 4.00- to 5.00-inch rim-width range, so wheel width matters too, not just the 13-inch diameter stamped into the fitment.
Does the 1974 MG Midget Base use the same tire size?
Yes. The 1974 MG Midget Base uses the same 145R13 radial tire size as the overall model fitment. There is no separate primary tire size to sort through for this sub-model, which keeps the fitment question simple and makes tire selection mostly a matter of comparing available products.
That consistency is helpful, but it still makes sense to inspect the actual wheels on the car before choosing a tire. A Midget that has been modified with different wheel widths, replacement rims, or suspension changes can need more careful checking for wheel compatibility and clearance than a stock-style setup.
Choosing the Right Tire
What should I consider when choosing a 145R13 tire for a 1974 MG Midget?
Start with the correct size and construction: 145R13 radial on a 13-inch rim. From there, compare the available tire series, the intended rim-width specification where it is given, and practical details such as tire weight, sidewall style, and the kind of road use the car is expected to see.
A restoration-minded owner may place more value on period-style appearance and classic branding, while a regularly driven Midget may push the decision toward a particular radial series within the same size. Wheel width should be checked carefully, since a tire that is correct in size still needs to suit the actual rim on the car.
What sidewall styles are available for 1974 MG Midget tires?
The available 145R13 tires for a 1974 MG Midget are offered in blackwall form. That gives the car a clean, understated look that suits a small British sports car and keeps the presentation simple for owners who want the tire to complement the Midget’s compact body lines.
Since the sidewall treatment does not vary here, the more meaningful visual choices come from brand and tire series rather than from stripes or whitewalls. Owners focused on appearance can compare how each blackwall radial supports a traditional look while still staying in the proper 145R13 size and 13-inch rim format.
What brands offer tires for the 1974 MG Midget?
Michelin and Firestone both offer 145R13 radial tires for the 1974 MG Midget. The available series include Michelin XAS-FF and Firestone F560 Radial, giving owners more than one established brand option while staying within the car’s single primary tire size.
Choosing between brands is best handled by looking at the specific tire series, wheel-width compatibility, and the kind of finish or driving impression you want from the car. Since both choices are blackwall radials in the correct size, the decision usually comes down to product character rather than basic fitment format.
Restoration & Appearance
Which tire should I choose for a period-style 1974 MG Midget?
A period-style starting point for a 1974 MG Midget is the correct 145R13 radial size on a 13-inch wheel. Staying with that size preserves the car’s visual balance, and the available Michelin and Firestone blackwall radials both support a traditional sports-car presentation without pushing the look into a modern oversized direction.
The final choice depends on whether the goal is a sympathetic restoration look or a more regularly driven road car that still respects the original format. Owners pursuing exact historical accuracy should compare brand, tread style, and finish against marque references or period photos rather than assuming any current tire is automatically factory-correct.
Does correct tire fitment matter for a 1974 MG Midget restoration?
Yes, correct tire fitment matters because the 1974 MG Midget is a small, lightweight car whose stance and proportions are strongly affected by tire size. Using the proper 145R13 radial on a 13-inch rim helps maintain the right visual scale and avoids the awkward look that often comes from overly wide or incorrect-diameter replacements.
Appearance is only part of the issue. The right size also helps keep steering clearance, wheel compatibility, and general drivability closer to what owners expect from a Midget. During restoration, it is worth checking the actual wheels on the car so a correct-looking tire choice also works sensibly with the chassis and body setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 MG Midget?
Yes. A 1974 MG Midget may have had wheel, suspension, or ride-height changes over the years, and those changes can alter what works even when the intended tire size is still 145R13. Aftermarket wheels can bring different widths or offsets that deserve attention before a new tire is selected.
Clearance around the fenders, steering components, and suspension should be checked on any modified car, especially one with lowered suspension or non-stock wheels. Even with the correct 13-inch rim diameter, a different wheel setup can change how the tire sits and behaves, so the actual car should guide the final fitment check.
What should I inspect before driving a 1974 MG Midget on new tires?
Before putting a 1974 MG Midget back into regular road use on new tires, inspect the wheels for damage or corrosion, confirm proper tire pressure, and make sure the tires are seated correctly on the rims. It also helps to check for suspension looseness, steering play, and any sign of rubbing at full lock.
A short, careful road test is a smart next step after installation. Pay attention to vibration, pull, unusual noise, or contact with bodywork during turns and bumps. Since the Midget is light and responsive, small setup issues can be easy to feel, and catching them early helps protect both the new tires and the car.
How should 145R13 tires on a collector 1974 MG Midget be maintained?
145R13 tires on a collector 1974 MG Midget should be checked regularly for air pressure, tread wear, sidewall cracking, bulges, cuts, and signs of slow air loss. Cars that are driven infrequently can look fine at a glance, yet still develop age-related issues that deserve attention before the next outing.
Storage conditions matter almost as much as mileage on a classic sports car. Keeping the car away from prolonged sunlight, excessive heat, moisture, and ozone sources can help preserve the tires between drives. Periodic inspection is especially important on a Midget because its light weight does not eliminate the effects of tire aging.
