The 1974 Volvo 164 sits at the refined end of Volvo’s rear-wheel-drive sedan lineup, combining the marque’s conservative engineering character with a more upscale six-cylinder touring feel. Buyers looking after one today are usually balancing road manners, correct visual proportion, and the practical realities of keeping a vintage European sedan in service. Tire fitment for the 1974 Volvo 164 centers on two 15-inch radial sizes: 175R15 and CR78-15. That gives owners a choice between a Euro-metric radial presentation and a vintage alphanumeric radial format. The key is matching the tire to the car’s exact look, wheel setup, and intended use before making a final selection.
Which Tire Size Is Right for The 1974 Volvo 164
The 1974 Volvo 164 uses two primary tire sizes, and both are radial tires built for 15-inch wheels. Because the covered 164 E sub-model uses both sizes, the real decision is not simply which tire fits the car, but which sizing format and overall presentation best suit the wheel setup, appearance goals, and driving use of the specific sedan.
175R15 is a Euro-metric radial size in which 175 refers to nominal section width in millimeters, R identifies radial construction, and 15 is the wheel diameter in inches. On a 1974 Volvo 164, this size reflects the metric-style sizing language commonly associated with European cars of the period. Its appeal is straightforward, especially for owners who want a traditional import-sedan tire format rather than a domestic-style alphanumeric code. This size is a strong choice to evaluate when preserving a classic European look matters as much as basic 15-inch radial fitment.
CR78-15 is an alphanumeric radial size, with the lettered prefix identifying the size class, the R marking radial construction, and the 15 indicating a 15-inch rim. For the 1974 Volvo 164, it offers a vintage sizing convention that reads differently from a metric radial even though it serves the same general 15-inch wheel format. Buyers often compare this kind of size for visual character as much as fitment, since alphanumeric tires can better match a period-style tire presentation. It is worth checking carefully against the car’s wheels and intended appearance before deciding between formats.
Sub-model fitment is straightforward here because the covered 1974 Volvo 164 E uses the same two 15-inch radial tire sizes. Checking the exact sub-model still matters, but the bigger decision is choosing between the Euro-metric 175R15 format and the vintage alphanumeric CR78-15 format.

Frequently Asked Questions
Common 1974 Volvo 164 tire questions usually come down to the two radial size formats, 15-inch wheel fitment, and how to choose a tire that suits restoration goals as well as regular road use.
Tire Size & Fitment
What tire size fits a 1974 Volvo 164?
The 1974 Volvo 164 uses two primary tire sizes: 175R15 and CR78-15. Both are radial tires designed for 15-inch wheels, so the main fitment question is not bias-ply versus radial, but which sizing format best matches the car’s wheel setup and the look the owner wants.
That matters because both sizes belong to different naming systems. A 175R15 follows a Euro-metric radial convention, while CR78-15 uses a vintage alphanumeric radial format. Before choosing between them, confirm the actual wheel diameter on the car and make sure the tire’s dimensions and profile suit the sedan’s clearance, stance, and intended use.
What size rim does a 1974 Volvo 164 use?
The applicable tire sizes for a 1974 Volvo 164 are built for a 15-inch rim. Both 175R15 and CR78-15 share that same 15-inch wheel diameter, which keeps rim diameter straightforward even though the tire sizes themselves are written in two different radial sizing formats.
Wheel diameter is only the first check. A car that has been changed over to aftermarket wheels still needs its wheel width and overall tire clearance reviewed before a tire is selected. On a vintage Volvo sedan, confirming the actual wheel setup on the car helps prevent confusion between correct 15-inch fitment and a tire that only appears close by size designation.
What does 175R15 mean on a 1974 Volvo 164?
On a 1974 Volvo 164, 175R15 is a Euro-metric radial tire size. The 175 refers to nominal section width in millimeters, the R indicates radial construction, and the 15 identifies the wheel diameter in inches. It is a classic European tire format that suits the character of a mid-1970s Volvo sedan.
The practical takeaway is that this size speaks to both fitment and presentation. It places the car in a metric radial sizing system rather than a domestic-style alphanumeric one such as CR78-15. When comparing tires, verify the actual wheel diameter first, then compare the tire’s overall proportions and how closely the finished look matches the way the 164 is being restored or driven.
Choosing the Right Tire
What should I consider when choosing a 175R15 tire for a 1974 Volvo 164?
Start with the basics: 175R15 is one of the primary radial sizes for the 1974 Volvo 164, and it belongs to a Euro-metric sizing tradition that feels natural on a vintage European sedan. The choice is less about whether the size belongs on the car and more about whether this format suits the look and driving plan better than CR78-15.
A careful selection should account for the wheel diameter already on the car, the tire’s visual proportion in the wheel opening, and whether the sedan is being kept close to a restoration-oriented appearance or used more casually on the road. It also helps to compare the wheel setup against any prior modifications so the chosen tire complements the car rather than simply matching the size code.
How do I choose between 175R15 and CR78-15 for a 1974 Volvo 164?
Both 175R15 and CR78-15 are primary radial sizes for the 1974 Volvo 164, so the decision comes down to tire format and presentation more than basic construction. The 175R15 uses a Euro-metric naming style, while CR78-15 uses a vintage alphanumeric radial designation that can create a different period impression.
A buyer comparing the two should think about how the car is being represented. A European-touring appearance may point naturally toward 175R15, while an owner drawn to a more vintage radial look may prefer CR78-15. Either way, confirm wheel diameter and check the actual wheel and body setup so the chosen tire works with the sedan’s stance and clearance.
What tire format makes the most sense for a 1974 Volvo 164?
For a 1974 Volvo 164, the most important format choice is between the Euro-metric 175R15 and the alphanumeric radial CR78-15. Both are valid 15-inch radial fitments for the car, but they communicate different eras and sizing conventions even before any brand or tread pattern enters the decision.
That means the right choice depends on what matters most to the owner. Some prefer the metric format because it aligns neatly with the Volvo’s European identity, while others like the vintage alphanumeric style for its period flavor. A useful final check is to compare how each size will look on the car’s current wheels and within the fender opening.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Volvo 164?
A period-style 1974 Volvo 164 can reasonably be approached through either 175R15 or CR78-15, since both are primary radial sizes for the car. The difference is mostly in the sizing language and the visual character that comes with it rather than in a change from one construction type to another.
For a restoration-minded owner, 175R15 often supports a classic European sedan presentation, while CR78-15 gives a more vintage alphanumeric radial impression. Exact originality questions should be checked against marque-specific historical references and the car’s own documentation. Once that goal is clear, compare wheel setup and overall tire appearance before settling on the final size.
Does correct tire fitment matter for a 1974 Volvo 164 restoration?
Correct tire fitment matters on a 1974 Volvo 164 restoration because tire size strongly affects stance, visual balance, and how authentic the finished car feels. Since this model uses 15-inch radial fitment in both 175R15 and CR78-15, the restorer is choosing between two legitimate size formats rather than forcing an unrelated modern specification onto the car.
The visual effect can be surprisingly important on a formal sedan like the 164. A tire that is technically close but stylistically out of place can change the car’s whole presentation. Good restoration practice is to confirm the wheel setup already on the vehicle and then choose the size format that best supports the intended period look without overlooking practical clearance and use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Volvo 164?
Yes, modifications can affect tire fitment on a 1974 Volvo 164 even when the chosen size is one of the correct 15-inch radial fitments. Wheel changes, altered ride height, suspension work, or body modifications can all influence how a 175R15 or CR78-15 sits in the wheel opening and how much clearance remains during steering and suspension travel.
That is why a car with aftermarket wheels should never be judged by size code alone. Confirm the actual wheel diameter and width on the car, then inspect for clearance at the fender edges and around steering components. A vintage Volvo used regularly on the road benefits from a careful fitment check before new tires go into service.
What should I inspect before driving a 1974 Volvo 164 on new tires?
Before driving a 1974 Volvo 164 on new tires, inspect the wheels for correct diameter and condition, confirm that the selected 175R15 or CR78-15 is mounted on the intended 15-inch setup, and check for proper inflation. It is also wise to look over suspension and steering components so the tire is not asked to compensate for worn hardware.
A short, careful test drive should follow, with attention paid to rubbing, unusual vibration, and how the car tracks. Collector vehicles that sit for long periods deserve extra caution because flat spotting, old wheel issues, or unnoticed alignment problems can show up quickly. A thorough inspection before regular use helps protect both the tires and the car.
How should tires on a collector 1974 Volvo 164 be maintained?
Tires on a collector 1974 Volvo 164 should be maintained with regular pressure checks, visual inspections, and attention to age-related condition as much as tread wear. Whether the car is running 175R15 or CR78-15 radials, look for cracking, cuts, bulges, and signs of air loss, especially if the sedan spends much of its time parked.
Storage conditions also matter. A low-use vintage Volvo is better protected when kept away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or generators. Even tires that appear lightly used deserve periodic inspection because collector cars often age out their tires long before they wear them out on the road.
