1967 Austin Tire Fitment Guide

1967 Austin vehicles use eight sizes across five models. The Austin 1100 uses 145R12 or 5.50-12 on 12-inch wheels, the Austin 1800 uses 175R13 or 650-13 on 13-inch wheels, the Austin 850 uses 145R10 or 5.20-10 on 10-inch wheels, the Austin A40 uses 145R13 or 520-13 on 13-inch wheels, and the Austin Mini Cooper shares 145R10 or 5.20-10 on 10-inch wheels. Rim width guidance appears with some products rather than every size, including 4.5 inches for 145R12, 4.50 to 5.00 inches for 650-13, 4.00 to 5.00 inches for 145R13, and 3.5 or 3.50 to 4.00 inches for 520-13.

The practical point is that 1967 Austin fitment is model-specific. A buyer who only knows the year and make still needs to identify the exact model before choosing a tire, because a Mini-size 10-inch tire, an 1100-size 12-inch tire, and an 1800- or A40-size 13-inch tire are not interchangeable just because they come from the same manufacturer family.

On a 1967 Austin, 145R10 is a Euro-metric radial size. The 145 is the nominal section width in millimeters, the R identifies radial construction, and the 10 is the wheel diameter in inches. In period European sizing, a missing aspect ratio is conventionally treated as an approximately 80-series profile. This size is used on the 1967 Austin 850 and 1967 Austin Mini Cooper.

That makes 145R10 the radial-path choice for Austin's smallest 10-inch-wheel cars. It keeps the correct wheel diameter while moving to radial construction, which many owners prefer for regular road driving. If your 1967 Austin is an 850 or Mini Cooper, confirming the wheel is still a 10-inch original-style setup is the first step before comparing brands within the size.

No, 1967 Austin models do not all use the same tire size. The 850 and Mini Cooper share 145R10 and 5.20-10, but the 1100 uses 145R12 and 5.50-12, the 1800 uses 175R13 and 650-13, and the A40 uses 145R13 and 520-13. Even where two models share a diameter, the actual tire size can still differ, as seen with the 1800 and A40 both using 13-inch wheels but not the same radial or bias-ply sizes.

That matters because 1967 Austin shopping starts with model identification, not just make recognition. If your car has been modified over the years, check the sidewall marking on the current tire and the wheel diameter before ordering. For restored or inherited cars, that simple step prevents confusion between similar-looking British small cars that use very different fitments.

For a 1967 Austin 850 or 1967 Austin Mini Cooper, the 145R10 is the radial option and the 5.20-10 is the bias-ply option. Both are 10-inch-wheel fitments for those two models, but they represent different construction eras and different driving character. The radial size is the more modern construction, while the bias-ply size keeps the earlier-style appearance and response many restorers expect on a period presentation.

Choose 5.20-10 when authenticity and original-style feel carry the most weight, especially for a restoration or show-minded build. Choose 145R10 when the car will spend more time on the road and you want a radial in the correct wheel diameter. The same logic applies across the wider 1967 Austin range: bias-ply generally supports originality, while radial generally supports more familiar modern road behavior.

Sidewall style depends on the size and model. The radial sizes with product coverage here, including 145R12, 145R10, and 145R13, are blackwall tires. The 650-13 bias-ply size for the Austin 1800 is available in narrow whitewall and wide whitewall form, while the 520-13 bias-ply size for the Austin A40 appears in blackwall and narrow whitewall versions. That gives the 13-inch bias-ply cars the broadest visual choice.

For a 1967 Austin, the right sidewall style often comes down to the look you want rather than basic fitment. Blackwalls usually suit a restrained British small-car appearance, while whitewalls create a more stylized period presentation that some owners prefer on export-market or personalized builds. If authenticity matters for judging, compare the sidewall style against period photos, marque-club guidance, and the market your car was built for.

Several brands cover 1967 Austin sizes. Michelin appears in 145R12 and 145R13, Coker Classic and US Royal cover 650-13, Firestone appears in 145R10, 145R13, and 520-13, Kings and Camac appear in 145R10, Dunlop appears in 145R10, and Premium Sport appears in 520-13. Brand choice therefore depends heavily on which Austin model and size you need rather than on the make alone.

That variety lets a buyer choose between more traditional restoration-oriented offerings and more road-use-focused radial options within the correct size. It also means one Austin owner may see completely different brand families than another depending on whether the car is an 850, 1100, 1800, A40, or Mini Cooper. Narrow your search by model and size first, then compare sidewall style, construction, and any stated load or speed details.

Rim width guidance for 1967 Austin tires varies by size. The 145R12 radial appears on a 4.5-inch rim, 650-13 bias-ply fits a 4.50 to 5.00-inch rim, 145R13 radial fits a 4.00 to 5.00-inch rim, and 520-13 bias-ply appears on either a 3.5-inch rim or a 3.50 to 4.00-inch rim depending on the product. Some sizes, including 145R10, 5.20-10, 5.50-12, and 175R13, do not carry width guidance here.

The safe approach is to confirm your wheel's actual width before ordering, especially on a modified or long-restored car. British small cars are often changed over time, and wheel swaps can blur what should fit. Matching the tire to the wheel matters for profile shape, clearance, and how the car behaves on the road, so measure first instead of assuming from the year alone.

Some 1967 Austin radial products are clearly marked tubeless. The Michelin 145R12 carries a TL marking, and the Michelin 145R13 also carries a TL marking. Other 1967 Austin sizes do not show a tube-type or tubeless marking here, so tube status can vary by product rather than by wheel diameter alone. That is especially important on older British wheels, where the wheel itself may influence whether a tube is appropriate.

Before fitting any 1967 Austin tire, check the sidewall marking on the exact tire you plan to use and inspect the wheel condition at the same time. A restorer should also consider the wheel's design, age, and sealing surface rather than assuming every reproduction tire is handled the same way. If there is any doubt, use the wheel and tire combination as a matched setup question rather than treating the tire alone as the whole answer.

A 1967 Austin should be stored away from direct sunlight, standing moisture, and ozone-producing equipment such as motors, welders, or compressors. Keep the tires clean and properly inflated, and move the car periodically so one contact patch is not carrying the load for months at a time. Bias-ply tires, which appear on several 1967 Austin fitments, are especially prone to taking a temporary set during long static storage.

If the car will sit for an extended season, many owners either roll it occasionally or support it in a way that reduces continuous load without leaving the suspension fully unloaded for years. A breathable indoor environment is far better than a damp cover outdoors. Good storage practice matters as much on a lightly used collector Austin as tread depth, because age and environment usually determine tire condition first.

On a 1967 Austin, tire age is usually more important than mileage. A collector car may wear out very little tread while still reaching the point where rubber hardens, cracks, or loses resilience. A sensible rule is to evaluate tires closely once they reach about five to seven years of age and to treat around ten years as the point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the tire helps establish age.

That timeline is especially relevant for a 1967 Austin because many surviving examples are hobby cars, not daily commuters. A radial that looks fresh and a bias-ply that still has deep tread can both be aged out if storage conditions have been poor. If the date code, sidewall condition, or road feel raises doubts, replacing the tires is usually wiser than trying to stretch another season out of old rubber.

Tires on a 1967 Austin should be checked before every drive and inspected more thoroughly before any longer outing. Look for sidewall cracking, weathering, bulges, punctures, uneven wear, and any sign that the tire is not holding pressure normally. On cars using older-style constructions or tube-related setups, valve stems and the condition around the rim also deserve attention because a small issue can become a trip-ending problem quickly.

A quick walkaround catches more than many owners expect, especially on a collector car that may sit between drives. Follow that with a more detailed inspection at seasonal intervals or whenever the car comes out of storage. On a small, light 1967 Austin, even modest tire problems can affect steering feel and stability, so tire inspection should be treated as part of the car's normal pre-drive routine, not an occasional chore.

For a 1967 Austin 1100, bias-ply construction was the traditional original-era tire type, and 5.50-12 represents that style of fitment on the model's 12-inch wheels. A 145R12 radial also fits the 1100, but radial construction reflects a different ownership choice than an authenticity-first restoration. Austin and BMC buyers in this period were living through the broader industry transition toward radials, so exact market and equipment details can vary by destination and specification.

If your goal is historical accuracy, start with the 5.50-12 bias-ply size and compare it against surviving factory literature, period photos, and Austin or BMC club guidance. If your goal is to drive the car regularly while staying within the proper wheel diameter, the 145R12 radial is the practical alternative. For show judging, always check the event's standard, because acceptable construction and sidewall appearance can differ by class.

Yes, correct tire fitment matters on a 1967 Austin because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall appearance immediately. A bias-ply Austin shown in a stock restoration class usually presents differently than the same car on modern radials, and a whitewall treatment can also change how authentic the finished car appears for its market and era. The right fitment is part of the car's overall stance and period character.

For serious show work, match the tire not just to the model but to the restoration goal. A Mini Cooper, 1100, or 1800 may all be correct in different ways depending on whether the car is restored as factory stock, preserved as-delivered, or finished in a period-custom style. Event rules, marque-club references, and original sales material are the best way to settle those finer points before mounting a full set.

For the 1967 Austin 1800 in 650-13, Coker Classic and US Royal share the same basic fitment facts here. Both are bias-ply tires, both fit 13-inch wheels with a 4.50 to 5.00-inch rim width range, both carry load figures of 1,150 pounds at 32 psi, and both are available in narrow whitewall and wide whitewall versions. The biggest visible difference is therefore the brand identity and sidewall presentation you want on the car.

That makes the decision less about dimensions and more about appearance and restoration style. If your Austin 1800 is being finished to a certain visual theme, choose the whitewall width and brand character that best match the car's intended period look. Since the core fitment numbers align closely, owners can focus on aesthetics and marque taste rather than trying to solve a major technical difference between the two.

1967 Austin tires can be suitable for highway driving when they are the correct size, in sound condition, and used within their marked limits. Some radial products carry explicit speed ratings, including S at 112 mph on 145R12 and 145R10, and H at 130 mph on one 145R13 application. Bias-ply sizes here do not show speed letters. On many 1967 Austin models, the car's own brakes, suspension, wheel size, and overall vintage design are often more relevant to real-world cruising than the tire's maximum speed ceiling.

The key is to match your expectations to the car and the tire together. A well-maintained Austin on fresh, correctly inflated tires is a very different proposition from a seldom-driven car on aged rubber, even if the tread still looks good. For regular road use, many owners favor radial construction where it is available, while show-oriented or originality-focused cars often stay with bias-ply and are driven accordingly.

Inflation pressure on a 1967 Austin should follow the vehicle's factory recommendation first, with the tire's own rated figures used as a load-and-capacity reference rather than copied blindly from one size to another. Several 1967 Austin tires include pressure-linked load figures: 650-13 shows 1,150 pounds at 32 psi, 520-13 appears at 770 pounds at 32 psi and 1,100 pounds at 60 psi depending on product, 145R10 shows 694 pounds at 30 psi on one product, and 145R13 shows 825 pounds at 44 psi on one product.

Those numbers help explain the tire's capacity, but they are not a substitute for the Austin's intended operating pressure. Small British cars can be sensitive to overinflation or underinflation, especially in front-wheel-drive layouts. Use the owner's manual or marque reference for baseline vehicle pressure, then confirm the exact tire's sidewall markings and product guidance so you are not applying one size's pressure logic to a different fitment.

Before a longer drive in a 1967 Austin, inspect every tire for cracking, cuts, bulges, uneven wear, and proper inflation, and do not forget the spare. Check that the valve stems are sound, especially on older wheels or tube-related setups, and make sure the tires have not aged out even if they still show good tread depth. On a collector British car, the tire inspection belongs alongside a broader pre-drive check of brakes, cooling, fluids, and charging system health.

That routine matters because long trips expose weaknesses that short local drives can hide. A tire that survives a quick run to a show can still become a problem after sustained heat and speed. If the car has been stored, put extra attention on flat-spotting, pressure loss, and sidewall condition before heading out. A few careful minutes in the garage are far easier than trying to solve preventable tire trouble on the roadside.
