The 1971 MG Midget represents the classic British small sports car formula at its most direct: light weight, simple mechanicals, and lively road manners that depend heavily on getting the tire choice right. Its compact proportions and tossable character make tire fitment more than a cosmetic detail, especially for owners balancing weekend driving with restoration-minded appearance. The 1971 MG Midget uses a 145R13 radial tire on a 13-inch rim. Within that size, available choices include Michelin and Firestone blackwall radials in distinct tire series. The real decision is how closely you want to preserve a traditional small-car look while confirming wheel compatibility and overall condition before road use.
Which Tire Size Is Right for The 1971 MG Midget
The 1971 MG Midget uses one primary tire size: 145R13, a radial tire that fits a 13-inch rim. The Base sub-model uses that same size, so the main choice is not between multiple fitments, but between available radial tire designs, product specifications, and the look you want for the car.
145R13 is a Euro-metric radial size in which 145 refers to nominal section width in millimeters, R identifies radial construction, and 13 is the wheel diameter in inches. This format is commonly associated with a classic 80-series radial profile, which suits the MG Midget’s compact proportions and period driving character. Available choices in 145R13 include blackwall radials from Michelin and Firestone, with tire series such as Michelin XAS-FF and F560 Radial. For most owners, the decision in this size comes down to matching the car’s intended use, wheel dimensions, and desired period-style presentation.
Tire fitment is straightforward for the covered 1971 MG Midget sub-models. The main reason to confirm the sub-model is simply to verify that the car remains on its original wheel diameter and has not been changed with aftermarket wheels or suspension modifications.

1971 MG Midget Base
The 1971 MG Midget Base uses the same 145R13 radial fitment as the model core, keeping tire selection simple at the sub-model level. That lets the focus shift to choosing between available blackwall radial options and confirming that the wheel width and overall setup still match the tire.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

These 1971 MG Midget tire FAQs focus on the 145R13 fitment, 13-inch wheel compatibility, radial tire selection, period-style appearance, and the checks worth making before putting a lightly used vintage sports car back on the road.
Tire Size & Fitment
What tire size fits a 1971 MG Midget?
The 1971 MG Midget uses a 145R13 radial tire. That is the primary fitment for this model year and it applies to the Base sub-model as well, so there is no split fitment within the covered configuration.
That makes size selection straightforward, but it is still worth confirming that the car remains on 13-inch wheels and has not been altered with aftermarket rims or suspension changes. Once the size is confirmed, the real comparison becomes tire series, brand, wheel-width compatibility, and the kind of traditional blackwall appearance you want on the car.
What size rim does a 1971 MG Midget use?
The 1971 MG Midget uses a 13-inch rim with its 145R13 tire size. Product fitments in this size are built around that same 13-inch wheel diameter, which is the key rim measurement to confirm before selecting a tire.
Wheel diameter is only part of the fitment picture on a small sports car. Actual wheel width should also be checked, especially if the car has replacement steel wheels or aftermarket alloys. Matching the tire to the correct rim diameter and an appropriate wheel width helps preserve steering response, clearance, and the balanced look expected from a Midget.
What does 145R13 mean on a 1971 MG Midget?
On a 1971 MG Midget, 145R13 means the tire has a nominal section width of 145 millimeters, radial construction, and fits a 13-inch wheel. In this older Euro-metric format, no aspect ratio is printed in the size itself.
For many vintage European cars, that unstated profile is commonly associated with an 80-series radial shape, which helps explain the tire’s tall, narrow look. Understanding the size code makes it easier to compare products in the same fitment and avoid accidentally choosing a modern low-profile tire that changes the car’s stance or wheel compatibility.
Choosing the Right Tire
What should I consider when choosing a 145R13 tire for a 1971 MG Midget?
Start with the correct size and construction: the 1971 MG Midget uses a 145R13 radial. From there, compare the available tire series, brand, blackwall presentation, and any stated rim-width or load specifications that relate to how the car is actually driven and maintained.
A lightly used collector car may call for a different buying emphasis than a regularly driven back-road car. Wheel condition, actual rim width, suspension health, and steering clearance all matter on a small chassis. Choosing carefully within the correct size helps keep the car’s proportions right without turning a simple fitment into an unnecessary experiment.
What brands offer tires for the 1971 MG Midget?
Michelin and Firestone both offer tires for the 1971 MG Midget in the correct 145R13 size. In this fitment, the available products are radial blackwall tires, including the Michelin XAS-FF series and the Firestone F560 Radial series.
That gives buyers a useful choice between established vintage-style tire lines without changing the basic fitment. The better comparison is not brand reputation in the abstract, but how each tire’s stated specifications, wheel-width compatibility where given, and overall look align with the way the Midget is set up and used.
What tire series are available for the 1971 MG Midget?
Two tire series are available in the 1971 MG Midget’s 145R13 fitment: Michelin XAS-FF and Firestone F560 Radial. Both are radial blackwall tires sized for the car’s 13-inch wheel application, but they give buyers different product lines to compare within the same basic fitment.
Series choice matters because owners often care about more than just size. On a vintage MG, the tire’s visual character, construction details, and wheel compatibility can all influence the final decision. Comparing by tire series helps narrow the field once size is settled, especially for owners trying to balance drivability with a traditional small-sports-car presentation.
Restoration & Appearance
Which tire should I choose for a period-style 1971 MG Midget?
For a period-style 1971 MG Midget, the right starting point is the correct 145R13 radial fitment. Keeping the original sizing format helps preserve the car’s tall, narrow tire look and avoids the visual mismatch that can come with wider or lower-profile modern substitutions.
Within that size, blackwall radials are available from Michelin and Firestone, which suits the understated presentation many owners want on a restored British sports car. Exact originality can depend on the car’s market, history, and restoration goal, so highly detailed projects benefit from comparing tire choices against period photos, marque references, and vehicle-specific documentation.
Does correct tire fitment matter for a 1971 MG Midget restoration?
Correct tire fitment matters a great deal on a 1971 MG Midget because the car’s proportions are so compact. A tire that strays too far from the proper 145R13 format can change the visual balance of the wheel opening, alter the stance, and distract from an otherwise well-finished restoration.
Fitment also affects how authentic the car feels on the road. The right size supports the light, nimble character buyers expect from a Midget, while incorrect wheel or tire combinations can introduce clearance and steering issues. Even when absolute originality is not the goal, staying close to the proper size keeps the car’s character intact.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1971 MG Midget?
Yes, modifications can affect tire fitment on a 1971 MG Midget even when the intended tire size remains 145R13. Aftermarket wheels, altered wheel width, suspension lowering, replacement springs, or body changes can all influence how much space the tire has during steering and suspension movement.
A small British sports car leaves less room for guesswork than a larger vehicle. Checking actual wheel diameter, wheel width, and visible clearance at the fender and suspension is wise before mounting new tires. Cars that have been modified over time should be treated as individual setups rather than assumed to match original wheel and tire conditions.
What should I inspect before driving a 1971 MG Midget on new tires?
Before driving a 1971 MG Midget on new tires, inspect the wheels for damage or corrosion, confirm the wheel diameter and width, and make sure the tires seat and inflate properly. Basic suspension and steering condition also matter, since worn components can make a lightweight car feel unsettled even with fresh tires installed.
A close look at alignment-related wear, brake drag, and any interference near the inner wheel well is also worthwhile. Collector cars often sit for long periods, so it is smart to recheck air pressure after installation and again after the first few drives. A careful pre-road inspection helps the new tires perform as intended from the start.
How should 145R13 tires on a collector 1971 MG Midget be maintained?
145R13 tires on a collector 1971 MG Midget should be maintained with regular pressure checks, visual inspections, and attention to age-related deterioration. Look for cracking, bulges, cuts, flat spotting from storage, uneven tread wear, and slow air loss, especially if the car is driven only occasionally.
Storage conditions matter as much as mileage on a vintage MG. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives. A short inspection before each outing and a more thorough check at regular intervals goes a long way toward protecting both appearance and road manners.
