The 1956 Austin A 95 came from a period when British family cars were growing larger, more capable, and more export-minded, blending practical saloon engineering with the broader proportions buyers expected in the mid-1950s. That character matters when choosing tires, because the car rides on a 670-15 bias-ply fitment mounted to a 15-inch wheel. Within that size, the choice is less about finding another primary size and more about selecting the right look and use case, from blackwall and whitewall bias-ply options to modern radial equivalents such as 195R15, P205/75R15, P215/70R15, and 670R15. The right selection depends on whether the goal is restoration-oriented appearance, traditional driving feel, or more modern road manners.
Which Tire Size Is Right for The 1956 Austin A 95
The 1956 Austin A 95 uses one primary tire size: 670-15 in bias-ply construction on a 15-inch rim. The covered Countryman sub-model uses that same size, so the main decision is not which primary fitment applies, but which 670-15 tire style best suits the car and whether a modern radial equivalent is worth considering after checking wheel compatibility and clearance.
A 670-15 is a vintage numeric bias-ply size in which the 670 represents an approximate 6.70-inch nominal section width and the 15 identifies the wheel diameter in inches. On the 1956 Austin A 95, this is the primary period-style fitment and it keeps the car in its original construction family rather than changing to a radial layout. Within 670-15, there is meaningful variety across brands such as Firestone, US Royal, BFGoodrich, Goodyear, Universal Vintage Tire, Excelsior, Avon, and STA, along with blackwall, narrow whitewall, and wide whitewall treatments. That makes 670-15 the size to evaluate when appearance, load specification, rim-width compatibility, and intended road use all matter.
Fitment is straightforward for the covered 1956 Austin A 95 sub-model. The main reason to check the sub-model is simply to confirm that the car still uses the expected wheel and tire setup before choosing among bias-ply styles or considering a radial equivalent.

1956 Austin A 95 Countryman
The 1956 Austin A 95 Countryman uses the same 670-15 bias-ply fitment as the model core, keeping tire selection centered on one primary size. That means the real choice is between blackwall or whitewall presentation, brand and series differences, or a carefully checked move to a radial equivalent.
Bias-Ply to Radial Tire Conversion for the 1956 Austin A 95
The original 670-15 tire size has four radial-equivalent choices. Those alternatives are 195R15 as an 80-series metric radial, P205/75R15 as a 75-series P-metric radial, P215/70R15 as a 70-series P-metric radial, and 670R15 as a bias-look radial equivalent. Together they offer a range from more conventional metric sizing to a radial designed to preserve a more traditional visual presentation. A recommended rim-width range of 5 to 7 inches is associated with these equivalents, and wheel size, overall fit, and clearance should still be checked before changing construction.

Tire Size & Fitment
What tire size fits a 1956 Austin A 95?
The 1956 Austin A 95 uses a 670-15 tire size in bias-ply construction. For the covered fitment here, that is the primary size associated with the car, and the Countryman sub-model uses the same 670-15 sizing rather than a different primary fitment.
That makes the buying decision more about choosing the right 670-15 tire than sorting through multiple factory-style sizes. Before ordering, it is still smart to confirm that the car retains 15-inch wheels and has not been changed to a different wheel or suspension setup, since collector vehicles are often modified over time.
What size rim does a 1956 Austin A 95 use?
The 1956 Austin A 95 uses a 15-inch rim with its 670-15 tire size. That 15-inch diameter is the key wheel measurement tied to the primary fitment and is also the rim diameter used by the available 670-15 bias-ply tire options.
Rim diameter is only one part of the wheel question, though, because tire products in this size also show different rim-width requirements. Measuring the actual wheel on the car helps prevent problems when selecting among bias-ply choices or evaluating a radial equivalent, especially if the car has replacement wheels from an earlier restoration.
Does the 1956 Austin A 95 Countryman use the same tire size?
Yes. The covered 1956 Austin A 95 Countryman uses the same 670-15 bias-ply tire size as the model core. That keeps fitment simple because there is no separate primary tire size to sort out for that sub-model before moving on to brand, sidewall, or construction decisions.
Even with shared sizing, the actual wheel on the car should still be checked before a purchase. A long-owned Countryman may have replacement rims, altered suspension height, or an older radial conversion, and those changes can influence whether staying with a 670-15 bias-ply tire or moving to a radial equivalent makes the most sense.
Bias-Ply & Radial Options
Is 670-15 a bias-ply or radial tire for the 1956 Austin A 95?
For the 1956 Austin A 95, 670-15 is the primary bias-ply tire size. That means the original-style fitment stays within the vintage numeric bias-ply format rather than using a metric or P-metric radial sizing convention as the starting point.
Keeping the car on 670-15 bias-ply tires preserves the traditional construction family and the period-style look associated with mid-1950s fitment. Owners considering a change in construction should treat that as a separate decision from the base size question and confirm wheel width, clearance, and overall setup before moving to any radial alternative.
What radial tire sizes are equivalent to 670-15?
Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. In that group, 195R15 is the 80-series metric radial option, P205/75R15 is the 75-series P-metric radial, P215/70R15 is the 70-series P-metric radial, and 670R15 is the bias-look radial alternative.
Those options give the 1956 Austin A 95 owner several ways to compare radial sizing while staying close to the original tire's role on the car. A recommended rim-width range of 5 to 7 inches is associated with the equivalents, but wheel dimensions and body clearance should still be verified before treating any of them as a usable substitute.
What should I check before converting my 1956 Austin A 95 from bias-ply to radial tires?
Start by confirming the car's actual wheel diameter and wheel width, then compare the radial equivalent you are considering for 670-15. The Austin A 95's primary fitment is bias-ply, so any move to 195R15, P205/75R15, P215/70R15, or 670R15 should begin with the wheel and tire dimensions, not just the size label.
The next checks are practical ones: steering clearance, fender space, suspension condition, and how the car is used. A low-mile collector car with replacement wheels or old suspension parts may react differently than an untouched example, so the conversion should be treated as a full fitment decision rather than a simple size-name swap.
Choosing the Right Tire
What should I consider when choosing a 670-15 tire for a 1956 Austin A 95?
The first priority is staying with the correct 670-15 size unless the car is being carefully evaluated for a radial equivalent. After that, compare construction, sidewall presentation, rim-width compatibility, load specification where stated, and the overall character of the tire series available in this vintage size.
A restoration-oriented Austin A 95 may call for a different look than a regularly driven car, even when both stay in 670-15. Blackwall, narrow whitewall, and wide whitewall options create very different visual results, so the best choice usually comes from balancing period-style appearance, wheel compatibility, and the way the car will actually be used.
What sidewall styles are available for 1956 Austin A 95 tires?
The 670-15 tires available for a 1956 Austin A 95 include blackwall, narrow whitewall, and wide whitewall sidewall styles. Because the car uses one primary size, sidewall treatment becomes one of the biggest visible differences between otherwise similar bias-ply options from different brands and series.
That choice affects the car's appearance more than its fitment, but it still matters to many owners. A blackwall gives a plainer, utility-minded presentation, while narrow and wide whitewalls move the car toward a more dressed, period-style look, so the right pick depends on how the Austin is being restored, displayed, or driven.
What brands offer tires for the 1956 Austin A 95?
The 1956 Austin A 95 has 670-15 tire options from Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA. Those brands appear across several bias-ply series, with differences in sidewall styling, stated rim-width compatibility, and some load specifications.
Brand choice should be considered alongside the exact tire series and the presentation you want on the car. Two 670-15 tires may share the same basic fitment while looking quite different, so comparing the details of blackwall versus whitewall styling and any wheel-width guidance is usually more useful than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1956 Austin A 95?
A period-style 1956 Austin A 95 usually starts with the original fitment family, which here means a 670-15 bias-ply tire on a 15-inch wheel. Staying in that size and construction keeps the car within the visual and dimensional language expected of a mid-1950s British saloon and estate-based model.
From there, the appearance decision shifts to brand character, tread presentation, and sidewall style rather than to a different primary size. Owners chasing a very specific restoration target should compare the tire choice against period photos, marque-club guidance, or vehicle history so the final look suits the particular car instead of a generic era impression.
How does tire construction affect the appearance of a restored 1956 Austin A 95?
Construction changes more than road feel on a restored 1956 Austin A 95; it also changes how the car looks. A 670-15 bias-ply tire keeps the traditional construction family, while radial equivalents such as 195R15, P205/75R15, P215/70R15, or 670R15 shift the car into a more modern tire format.
That difference can matter when the goal is a restoration-oriented presentation. A bias-look radial offers one middle ground because it is a radial equivalent intended to preserve a more traditional visual impression, but wheel fit and overall proportions should still be checked carefully before deciding that appearance and construction goals are aligned.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1956 Austin A 95?
Yes. Modifications can change tire fitment on a 1956 Austin A 95 even when the original reference size is 670-15. Aftermarket wheels, different wheel widths, suspension changes, ride-height adjustments, or body and brake modifications can all alter the space available for the tire and influence whether the car still matches the expected setup.
That is especially important on older cars that may have passed through several owners and restorations. Measuring the actual wheel and checking steering and fender clearance will usually tell you more than the badge on the trunk, and those checks matter even more if a radial equivalent is being considered instead of a bias-ply tire.
What should I inspect before driving a 1956 Austin A 95 on new tires?
Before driving a 1956 Austin A 95 on new tires, inspect the wheels, valve stems, lug hardware, and the basic condition of the suspension and steering. The tires themselves should be checked for proper inflation, even seating on the rim, and any signs of immediate air loss after installation.
A short local test drive is a sensible next step because it gives the car time to show any rubbing, pull, vibration, or clearance issue at low speed. Older collector vehicles can reveal problems that were hidden by aged tires, so the first miles should focus on feel, tracking, and visible wheelhouse clearance.
How should 670-15 tires on a collector 1956 Austin A 95 be maintained?
670-15 tires on a collector 1956 Austin A 95 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Tread condition, sidewall cracking, cuts, bulges, and slow air loss all matter on a low-use vintage car, even when the tires still look presentable at a glance.
Storage conditions also play a big role in tire life on a car that is not driven daily. Keeping the Austin away from prolonged sunlight, excessive heat, moisture, and ozone sources helps protect the rubber, and periodic inspection remains important because age and inactivity can be just as hard on collector tires as road miles.
