The 1973 Volvo 164 sits in the era when Volvo's six-cylinder sedan blended conservative engineering with upscale comfort and long-distance road manners. Buyers looking after one today are often balancing authentic European character with practical touring use, especially on a car meant to feel composed rather than flashy. For this exact model, the tire decision centers on two 15-inch radial sizes: 175R15 in Euro-metric form and CR78-15 in vintage alphanumeric radial form. That creates room to think about sizing convention and period-style presentation instead of choosing between bias-ply and radial construction. The right choice starts with the car's existing wheel setup and the look you want to preserve.
Which Tire Size Is Right for The 1973 Volvo 164
The 1973 Volvo 164 uses two primary tire sizes, and both are radial tires for 15-inch wheels. Since the same two sizes appear on the covered sub-model, the main task is not identifying a different trim fitment but deciding which sizing convention best matches the car's current wheel setup, appearance goals, and intended road use.
A 175R15 uses a 175-millimeter nominal section width, radial construction, and a 15-inch rim diameter. In this older Euro-metric format, the aspect ratio is not stated in the size itself, so it is best read as a traditional metric radial rather than compared loosely to a modern low-profile tire. On a 1973 Volvo 164, this size suits buyers who want a metric-style radial presentation that feels appropriate to the car's European character. It is a strong size to evaluate when maintaining a traditional imported-sedan look matters as much as everyday drivability.
CR78-15 is an alphanumeric radial size where the letter code identifies the tire's size class and the final number identifies a 15-inch wheel. This format carries a distinctly vintage replacement character, making it especially familiar to buyers shopping for classic-era fitment rather than modern metric labeling. On the 1973 Volvo 164, CR78-15 offers a radial construction with an older size convention that can better suit a period-style presentation. It is worth considering when the goal is to keep the car visually closer to the replacement-tire language common during its era.
Sub-model fitment is straightforward for the 1973 Volvo 164 range covered here. The 164 E uses the same 15-inch radial size choices, so selection comes down to tire format, appearance, and wheel confirmation rather than a separate trim-specific fitment path.

1973 Volvo 164 E
The 1973 Volvo 164 E uses the same two radial tire sizes found on this model line, both built for 15-inch wheels. That keeps the focus on choosing between Euro-metric 175R15 and vintage-style CR78-15 based on the car's current setup and the look you want on the road.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Owners of a 1973 Volvo 164 usually want clarity on the two radial tire sizes, how the 164 E fits into that picture, and what to verify before choosing tires for appearance, wheel compatibility, and road use.
Tire Size & Fitment
What tire size fits a 1973 Volvo 164?
The 1973 Volvo 164 uses two primary tire sizes: 175R15 and CR78-15. Both are radial tires and both are intended for 15-inch wheels, so the fitment question is less about bias-ply versus radial and more about which size format best matches the car's wheel setup and the look you want.
A 175R15 is a Euro-metric radial, while CR78-15 uses a vintage alphanumeric radial format. Before choosing between them, confirm the wheel diameter on the car and compare the existing tire labeling, especially if the car has been driven on replacement tires for many years or has had wheel changes at some point.
What size rim does a 1973 Volvo 164 use?
The 1973 Volvo 164 uses a 15-inch rim diameter with both applicable tire sizes, 175R15 and CR78-15. That means the core wheel-diameter requirement stays the same even though the tire size can be expressed in two different radial sizing systems.
Rim diameter should be verified directly on the wheel before ordering tires, especially on a collector car that may have seen later replacements. Diameter is only the first check, though. Wheel width and the overall tire's relationship to the fender opening and suspension are still worth reviewing before settling on one size format over the other.
Does the 1973 Volvo 164 E use the same tire size?
Yes. The 1973 Volvo 164 E uses the same two tire sizes as the 1973 Volvo 164: 175R15 and CR78-15. Both are radial tires for 15-inch wheels, so there is no separate sub-model-only size that changes the basic fitment direction for the E.
That shared fitment makes selection simpler, but it does not eliminate the need to inspect the actual car. A 164 E with replacement wheels, older imported tires, or appearance-focused changes may benefit from comparing the current tire size and wheel dimensions before choosing between the Euro-metric and alphanumeric radial formats.
Choosing the Right Tire
What should I consider when choosing a tire for a 1973 Volvo 164?
Start with the correct primary fitment: 175R15 or CR78-15, both in radial construction for a 15-inch wheel. From there, the main decision is whether the car is better served by a Euro-metric radial presentation or a vintage alphanumeric radial presentation, since each size speaks to a slightly different classic-tire look.
The best choice depends on how the car is used and how it is equipped now. A carefully preserved sedan may call for a more period-style appearance, while a regularly driven car may be easier to evaluate against the existing metric tire setup. Confirm wheel diameter, inspect current clearances, and compare your present tire markings before deciding.
How do I choose between 175R15 and CR78-15 tires for a 1973 Volvo 164?
The choice comes down to size format and presentation, since both are radial tires for the same 15-inch rim diameter. A 175R15 follows a traditional Euro-metric convention, while CR78-15 uses an alphanumeric radial convention that often appeals to buyers seeking a more vintage replacement style.
Checking what is already on the car can help narrow the decision quickly. A Volvo 164 that has long worn metric radials may be easier to keep in that family, while a car being refreshed for a more era-appropriate appearance may justify a closer look at CR78-15. Wheel width and surrounding clearance should still be reviewed before making the change.
What tire series are available for the 1973 Volvo 164?
Tire selection for the 1973 Volvo 164 is centered more on the two correct radial size formats than on a broad published spread of series choices. The meaningful comparison on this vehicle is usually 175R15 versus CR78-15, rather than sorting through many clearly defined series families within the same fitment.
That makes the buying process a little more focused. Instead of chasing a series name first, confirm which size convention belongs on the car as it sits today. Once the wheel and present tire setup are understood, it becomes easier to choose a tire that supports the desired balance of appearance, fitment confidence, and regular road use.
Restoration & Appearance
Which tire should I choose for a period-style 1973 Volvo 164?
A period-style 1973 Volvo 164 usually starts with choosing between 175R15 and CR78-15, since both are correct primary radial fitments for 15-inch wheels. The 175R15 leans toward a traditional imported metric presentation, while CR78-15 carries an older alphanumeric style that can look more era-oriented on a classic sedan.
Appearance goals should be balanced against the car's actual setup. A restored or preserved 164 may look most cohesive with the size format that matches its current wheels and overall visual theme. When exact originality matters, compare the car against marque-specific historical references rather than assuming one replacement-style size presentation is automatically the right answer.
Does correct tire fitment matter for a 1973 Volvo 164 restoration?
Yes, correct tire fitment matters on a 1973 Volvo 164 restoration because tire size affects both visual balance and how authentically the car presents. With 175R15 and CR78-15 both in play, the restoration decision is not just about mounting any 15-inch radial, but choosing a size format that suits the car's era and stance.
A mismatched tire can make an otherwise careful restoration feel visually off, even before the car moves. Tire labeling style, sidewall shape, and overall presentation all contribute to how the 164 reads as a finished classic. That is why wheel diameter, existing setup, and the restoration goal should be reviewed together before final tire selection.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1973 Volvo 164?
Yes. A 1973 Volvo 164 may use 175R15 or CR78-15 on a 15-inch wheel, but modifications can still change what works safely and cleanly on the car. Aftermarket wheels, altered wheel width, suspension changes, or body work can all affect clearance even when the tire size itself looks appropriate on paper.
A collector car often carries changes made years ago, so it helps to inspect rather than assume. Look at wheel markings, measure available space near the fenders and suspension, and turn the steering through its full range when evaluating the front end. Those checks matter whether the goal is a stock look or a more personalized setup.
What should I inspect before driving a 1973 Volvo 164 on new tires?
Before driving a 1973 Volvo 164 on new tires, inspect the wheels for correct 15-inch diameter, check that the mounted size matches the intended fitment, and confirm there is no contact at the fenders or suspension. It also helps to verify valve stems, lug hardware, and inflation pressure before the first longer outing.
A sound tire installation is only part of the picture on an older sedan. Look over steering and suspension condition, since worn components can affect how the car tracks and how the tires wear. After a short initial drive, recheck air pressure and inspect for any rubbing marks so small fitment issues are caught early.
How should tires on a collector 1973 Volvo 164 be maintained?
Tires on a collector 1973 Volvo 164 should be checked regularly for air loss, sidewall cracking, cuts, bulges, and uneven tread wear, even if the car is driven only occasionally. Low-use classics can age tires quietly, so visual condition matters just as much as remaining tread depth on either 175R15 or CR78-15 fitment.
Storage habits make a difference over time. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires between drives. It is also smart to inspect the tires before any longer trip, since a classic that sits for weeks or months may develop pressure loss or age-related issues without obvious warning.
