The 1967 Morris Mini Minor sits at the heart of the original Mini story, a compact British car whose packaging, road manners, and unmistakable stance made it far more influential than its small footprint suggests. For many owners, tire choice is a big part of preserving that character. This Mini Minor uses two primary 10-inch fitments: a 145R10 radial or a 5.20-10 bias-ply. That opens the door to different approaches, from traditional bias-ply presentation to more modern radial construction, with several blackwall radial choices available. The right decision comes down to the car’s current wheel setup, the driving feel you want, and how closely the finished look should follow a period-style restoration.
Which Tire Size Is Right for The 1967 Morris Mini Minor
The 1967 Morris Mini Minor uses two primary tire sizes, and the difference is construction rather than rim diameter since both fit a 10-inch wheel. The key first step is deciding whether your car is staying with the traditional 5.20-10 bias-ply format or using the 145R10 radial size. Once that is settled, the real comparison shifts to tire series, brand, and the kind of road feel and appearance that best suit the car.
145R10 is a Euro-metric radial size: 145 refers to the nominal section width in millimeters, R indicates radial construction, and 10 is the wheel diameter in inches. On a 1967 Morris Mini Minor, this size represents the radial fitment path and gives buyers a more modern sizing convention while staying on the correct 10-inch rim. Available choices include Firestone, Kings, Camac, Dunlop, and Vredestein, all in blackwall form across several radial series. It is the size to evaluate when the goal is a radial-equipped Mini with period-friendly proportions and multiple brand options.
5.20-10 is a numeric bias-ply size in which 5.20 refers to the nominal section width in inches and 10 identifies the wheel diameter. That makes it the traditional bias-ply fitment for the 1967 Morris Mini Minor and an important choice for owners who want an earlier construction type and a more vintage tire presentation. Bias-ply construction can also matter to restoration-minded buyers who want the car to retain a distinctly period-style look. It is the size to consider when appearance and construction style matter more than moving to a radial format.
Fitment is straightforward for the covered 1967 Morris Mini Minor sub-model because the same two primary tire sizes are associated with it. Checking the exact sub-model still matters, but the main decision here is construction choice rather than sorting through different wheel diameters or trim-specific tire sizes.

Tire Size & Fitment
What tire size fits a 1967 Morris Mini Minor?
The 1967 Morris Mini Minor uses two primary tire sizes: 145R10 in radial construction and 5.20-10 in bias-ply construction. Both sizes are tied to the car and both use a 10-inch rim, so the fitment question is less about wheel diameter and more about choosing the construction style that matches the car’s setup and intended use.
That distinction matters because a Mini on radial tires can have a different driving character and tire appearance than one on bias-ply tires. Start by confirming the wheels currently on the car, then choose the size and construction that suit your restoration goals, road use, and overall presentation.
What size rim does a 1967 Morris Mini Minor use?
The 1967 Morris Mini Minor uses a 10-inch rim with both of its primary tire sizes. The radial 145R10 and the bias-ply 5.20-10 are both built around that same wheel diameter, which keeps the first fitment check simple compared with cars that used multiple rim diameters across different configurations.
Wheel diameter is only one part of the decision, though. A Mini that has been fitted with replacement wheels over the years should also have its wheel width and general clearance checked before changing tire construction, especially when moving between a traditional bias-ply setup and a radial-equipped setup.
What does 5.20-10 mean on a 1967 Morris Mini Minor?
On a 1967 Morris Mini Minor, 5.20-10 is a numeric bias-ply size. The 5.20 refers to the nominal section width in inches, and the 10 refers to the rim diameter in inches. It is an older sizing format that many vintage vehicle owners still encounter when working with period-style tires and restoration-oriented fitments.
Understanding that format helps separate the bias-ply option from the radial 145R10 size used on the same Mini Minor. The numbers do not translate directly into a modern metric radial formula, so the smartest approach is to verify the wheel setup first and then choose the construction that matches the car’s intended look and use.
Bias-Ply & Radial Options
Is 5.20-10 a bias-ply or radial tire for the 1967 Morris Mini Minor?
For the 1967 Morris Mini Minor, 5.20-10 is a bias-ply tire size. It uses the older numeric sizing format commonly associated with vintage bias-ply construction, while the radial option for this car is the separate 145R10 size. That makes 5.20-10 the traditional-construction choice among the two primary fitments.
Choosing it usually comes down to keeping a more vintage tire presentation and construction style on the car. Before making the switch from radial to bias-ply or staying with bias-ply, confirm the wheel setup and make sure the rest of the vehicle’s condition and use match the tire style you want to run.
Should I use bias-ply or radial tires on a 1967 Morris Mini Minor?
A 1967 Morris Mini Minor can be set up with either 5.20-10 bias-ply tires or 145R10 radial tires. The bias-ply route leans toward a more traditional period-style presentation, while the radial route keeps the car on a 10-inch wheel with a more modern construction type and several available blackwall tire choices.
The best direction depends on how the Mini will be used and how closely the tire appearance should follow a vintage look. A car built around restoration priorities may point one way, while a regularly driven Mini may point another, so the wheel setup and overall vehicle condition should be checked before deciding.
What should I check before converting my 1967 Morris Mini Minor from bias-ply to radial tires?
A 1967 Morris Mini Minor uses 5.20-10 as its bias-ply size and 145R10 as its radial size, so the first step is confirming that the car’s 10-inch wheels are appropriate for the radial you plan to use. The conversion decision should also take into account the car’s existing setup rather than assuming every Mini remains configured exactly as it left the factory.
After wheel diameter is confirmed, inspect wheel width, steering clearance, and fender clearance, especially if the car has been modified or sits differently than stock. It also helps to review suspension condition and general tire age on any collector car before putting fresh tires into service.
Choosing the Right Tire
What should I consider when choosing a 145R10 tire for a 1967 Morris Mini Minor?
Choosing a 145R10 tire for a 1967 Morris Mini Minor starts with confirming that the car is set up for the radial fitment rather than the 5.20-10 bias-ply size. Once that is settled, the most useful comparisons are among the available radial series and brands, including Firestone, Kings, Camac, Dunlop, and Vredestein.
It also helps to look at the finer differences between products, such as sidewall presentation, construction details, and load information where it is shown. A Mini used mostly for shows may point toward one kind of presentation, while a road-driven car may lead you to compare practical radial options more closely.
What sidewall styles are available for 1967 Morris Mini Minor tires?
For the available 145R10 radial products associated with the 1967 Morris Mini Minor, the sidewall style is blackwall. That keeps the appearance simple and consistent across the radial offerings, even though the tire series and brand choices vary. Blackwall presentation suits the Mini’s compact, functional look and gives buyers a straightforward visual starting point.
Since sidewall treatment is not where most of the variation appears here, the more meaningful comparisons are construction type, brand, and tire series. Owners focused on a period-style finish should also consider whether the broader look of a blackwall radial or the traditional bias-ply construction better matches the car they are building.
What brands offer tires for the 1967 Morris Mini Minor?
The 145R10 radial fitment for the 1967 Morris Mini Minor is available from Firestone, Kings, Camac, Dunlop, and Vredestein. Those brands cover several different radial tire series while staying within the same basic size and 10-inch rim format, which gives Mini owners a useful spread of choices without changing the primary radial fitment path.
Brand alone should not be the only deciding factor. Compare the tire series, sidewall presentation, and any useful specification details shown for each product, then match those details to the way the car will be driven and the kind of overall appearance you want the finished Mini to have.
Restoration & Appearance
Which tire should I choose for a period-style 1967 Morris Mini Minor?
For a period-style 1967 Morris Mini Minor, the main starting point is deciding whether the car should keep the traditional 5.20-10 bias-ply look or use the 145R10 radial size. The bias-ply option generally aligns more naturally with an earlier tire presentation, while the radial option offers a later construction style in the same 10-inch wheel diameter.
That choice depends on how strictly the car is being restored and what visual character matters most to you. When exact originality is the goal, it is worth checking marque references or restoration documentation, because a period-style tire is not automatically the same thing as a proven factory-delivered tire specification.
How does tire construction affect the appearance of a restored 1967 Morris Mini Minor?
Tire construction changes more than road feel on a restored 1967 Morris Mini Minor; it also changes the visual character of the car. A 5.20-10 bias-ply tire tends to support a more traditional vintage presentation, while a 145R10 radial gives the Mini a more modern construction approach even though it remains on the correct 10-inch wheel diameter.
That makes construction one of the first appearance decisions in a restoration, not just a mechanical one. Buyers often choose between preserving an earlier look and choosing a radial-based setup that still respects the car’s compact proportions, so the final tire should suit both the build style and how the Mini will be used.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1967 Morris Mini Minor?
Yes, modifications can affect tire fitment on a 1967 Morris Mini Minor even when the vehicle uses one of its known 10-inch tire sizes. Wheel changes, altered ride height, suspension work, or body modifications can all influence how much room the tire has in use, especially around steering travel and fender clearance.
That is why a modified Mini should be measured and inspected before changing between 5.20-10 bias-ply and 145R10 radial tires. A car that sits lower or uses non-original wheels may need more careful checking than a standard example, even when the tire size itself is one associated with the model.
What should I inspect before driving a 1967 Morris Mini Minor on new tires?
Before driving a 1967 Morris Mini Minor on new tires, inspect the wheels for correct diameter and sound condition, then check that the tires are properly seated and inflated. It is also smart to look over suspension and steering components on a small, responsive car like the Mini, since worn parts can affect how a fresh tire behaves on the road.
A visual inspection should also cover clearance through the steering range and any signs of rubbing near the fenders or suspension. Once the car is moving again, recheck air pressure and look for any unusual wear pattern or contact mark that suggests the wheel and tire combination needs closer attention.
How should tires on a collector 1967 Morris Mini Minor be maintained?
Tires on a collector 1967 Morris Mini Minor should be maintained with regular pressure checks, periodic visual inspections, and attention to age even when the car is not driven often. Collector cars can spend long periods parked, and that makes it especially important to watch for sidewall cracking, bulges, cuts, flat-spotting, and slow air loss.
Storage conditions matter too. Keeping the Mini away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition, and moving the car occasionally can help prevent problems associated with long stationary periods. Any sign of deterioration should be taken seriously before returning the car to regular road use.
