1964 Volvo 122 Tires

The 1964 Volvo 122 does not use one universal tire size across every covered configuration. The S Series uses either 165R15 radial or 590-15 bias-ply tires, while the S Wagon uses 640-15 or 7.35-15 bias-ply tires. All of these are 15-inch fitments, but they are not interchangeable simply because the rim diameter matches.

The practical first step is identifying whether the car is an S Series or an S Wagon. From there, check the wheels actually on the vehicle and compare the current tire size before selecting a replacement, especially if the car has been modified or changed from bias-ply to radial at some point in its life.

The primary tire fitments for the 1964 Volvo 122 all use a 15-inch rim diameter. That applies to the 165R15 radial as well as the 590-15, 640-15, and 7.35-15 bias-ply sizes. Rim diameter is consistent here, even though the actual tire size and construction vary by sub-model.

A shared 15-inch rim diameter does not remove the need to check wheel width and the exact size already on the car. Bias-ply and radial tires can have different rim-width recommendations, so the wheel should be measured and matched to the intended tire rather than assuming any 15-inch tire will be suitable.

More than one tire size appears on the 1964 Volvo 122 because fitment changes by sub-model and construction type. The S Series includes both a radial size, 165R15, and a bias-ply size, 590-15, while the S Wagon uses larger bias-ply sizes, 640-15 and 7.35-15. That creates several valid primary fitment paths within the same model year.

This matters because replacement tire shopping starts with the exact version of the car, not just the model name. A sedan-style S Series decision can involve radial versus bias-ply, while the wagon decision centers more on choosing the correct wagon-specific bias-ply size and confirming the wheel setup before any substitution is considered.

590-15 is a bias-ply tire size for the 1964 Volvo 122 S Series. It uses the vintage numeric bias-ply sizing system, where the leading number reflects nominal width and the 15 identifies rim diameter. It is separate from the 165R15 radial fitment, even though both sizes relate to the same sub-model family.

Choosing 590-15 usually points toward a more traditional driving feel and period-style appearance. Anyone considering a move from 590-15 to a radial alternative should verify wheel width, compare the car's current setup, and check clearance carefully rather than assuming that every radial with the same rim diameter can be used without further evaluation.

For 590-15, radial equivalents include 165R15, P165/75R15, and P175/70R15. For 640-15, radial equivalents include 175R15, P175/75R15, and P185/70R15. The 165R15 and 175R15 sizes are 80-series metric radials, while the P-metric alternatives offer 75-series and 70-series radial formats.

Those equivalents give a useful range of radial options, but they should be treated as alternatives to evaluate rather than automatic replacements. Rim-width guidance is also part of the picture, with 590-15 equivalents associated with 4 to 5 inch rims and 640-15 equivalents associated with 5 to 6 inch rims, along with normal clearance and wheel-fit checks.

A bias-ply to radial conversion on a 1964 Volvo 122 starts with the original size on the car and the specific radial equivalent available for that size. Wheel width should be confirmed first, because the established equivalents for 590-15 and 640-15 include recommended rim-width ranges that need to match the wheels actually on the vehicle.

The next checks are overall fitment and condition rather than construction alone. Steering clearance, fender clearance, suspension condition, and any previous wheel changes all matter, especially on an older car that may no longer be on its original setup. A radial equivalent can be a sound alternative, but it still needs to be verified against the car in front of you.

Start with the exact sub-model and tire size, because a 1964 Volvo 122 can use 165R15, 590-15, 640-15, or 7.35-15 depending on configuration. Construction is the next decision, especially on the S Series where both radial and bias-ply fitments appear. After that, compare wheel compatibility, sidewall style, brand, and whether the car is being kept in a traditional presentation or driven more regularly.

Selection gets easier once the purpose of the car is clear. A restoration-oriented car may lean toward a period-style bias-ply look, while a road-driven S Series may steer the buyer toward the 165R15 radial family. The right choice comes from matching size, wheel setup, and appearance goals rather than picking by brand name alone.

Sidewall choices for 1964 Volvo 122 tires include blackwall, narrow whitewall, and wide whitewall, depending on size and tire series. The radial 165R15 category offers all three looks, while the bias-ply sizes also include blackwall and whitewall options. That gives owners room to tailor the car's appearance without changing the primary fitment category.

The best sidewall choice depends on the look you want from the car rather than a universal rule. Blackwall usually gives a restrained, functional presentation, while narrow or wide whitewalls move the car toward a more restoration-oriented style. Once the proper size is confirmed, sidewall treatment becomes one of the easiest ways to shape the finished appearance.

Tires for the 1964 Volvo 122 are available from Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, Vredestein, Avon, and Excelsior across the covered sizes. Brand availability depends on the exact size, with the 165R15 radial category offering the broadest spread and the bias-ply sizes narrowing the field to more traditional vintage tire lines.

Brand choice should be compared alongside construction, sidewall style, rim-width compatibility, and tire series rather than treated as the whole decision. A buyer looking at 165R15 may be comparing classic touring radials and whitewall variations, while someone shopping 640-15 is more likely sorting through blackwall versus whitewall bias-ply options in the correct vintage format.

A period-style 1964 Volvo 122 tire choice begins with the proper size for the exact sub-model, then usually points toward the bias-ply options tied to that configuration. The S Series can use 590-15 bias-ply, while the S Wagon uses 640-15 or 7.35-15 bias-ply sizes. Those fitments preserve the vintage sizing language and traditional construction associated with the car's era.

Appearance still leaves room for choice, especially where blackwall and whitewall versions are available. For a careful restoration, tire selection should also be cross-checked against photos, marque-club guidance, or other model-specific historical references if exact originality matters. That extra step helps separate a broadly period-style result from a truly research-driven restoration.

Tire construction changes the visual character of a restored 1964 Volvo 122 as much as it changes the driving setup. A bias-ply tire brings a distinctly vintage presentation that suits the car's early-1960s feel, while a radial such as 165R15 gives a more modern-looking tire format even when offered with traditional blackwall or whitewall styling.

That difference matters most on the S Series, where both constructions are part of the fitment picture. Buyers restoring for visual authenticity often start with the correct bias-ply size, while buyers emphasizing regular road use may consider the radial route. The decision is less about right versus wrong and more about matching the car's finished purpose and appearance.

Yes, modifications can affect tire fitment on a 1964 Volvo 122 even when the tire size itself is correct on paper. Aftermarket wheels, wheel-width changes, altered ride height, suspension work, or body changes can all influence how a 15-inch tire sits in the car. That matters with both bias-ply sizes and radial alternatives.

A changed setup should be inspected as a complete package before new tires are chosen. Measure the actual wheel width, confirm the current tire clearance at full steering travel, and compare the vehicle's present configuration against the intended replacement size. Older cars often carry decades of small changes, and tire selection should account for those changes directly.

Before road use, inspect the wheels, valve stems, lug hardware, and the basic clearance around the new tires on the 1964 Volvo 122. The tires themselves should be checked for correct inflation, proper bead seating, and any early signs of rubbing at the fenders or suspension. This is especially important when changing construction type or moving to a radial equivalent.

The first few drives should be treated as a follow-up inspection period rather than the end of the job. Recheck air pressure, look for uneven contact or marks inside the wheel openings, and pay attention to any vibration or pull. Catching a wheel-compatibility or clearance issue early is much easier than discovering it on a longer drive.

Collector-car tires on a 1964 Volvo 122 should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Even low-mileage tires can age from time, sunlight, heat, and long periods of sitting. Sidewall cracking, flat spotting, cuts, bulges, and gradual air loss all deserve attention before the car is put back on the road.

A good routine is to inspect the tires before each drive and more thoroughly whenever the car has been parked for an extended period. Moving the car occasionally, storing it away from ozone sources and direct sun, and correcting pressure loss promptly all help preserve both radial and bias-ply tires on a lightly used vintage Volvo.
