The 1964 Alfa Romeo 1600 sits in a sweet spot for Italian enthusiast cars, blending compact dimensions, lively road manners, and the crisp design language that made Alfa sedans, coupes, and spiders so appealing in the 1960s. Tire choice matters here because the car can be fitted with either a 560-15 bias-ply or a 155R15 radial, both on 15-inch rims. That opens the door to very different ownership paths, from traditional bias-ply styling with blackwall or whitewall options to metric radial choices from Firestone, Michelin, Avon, and Vredestein. The right selection depends on whether appearance, driving feel, and restoration goals point toward vintage construction or a radial alternative.
Which Tire Size Is Right for The 1964 Alfa Romeo 1600
The 1964 Alfa Romeo 1600 uses two primary tire sizes, and the choice centers on construction rather than wheel diameter since both fit a 15-inch rim. A 560-15 bias-ply and a 155R15 radial are both associated with this model family, so the real decision is whether to keep a traditional vintage presentation or move toward a radial setup that still suits the car's proportions.
155R15 is a Euro-metric radial size in which 155 represents the nominal section width in millimeters, R designates radial construction, and 15 is the wheel diameter in inches. On the 1964 Alfa Romeo 1600, this size speaks to a more modern radial approach while still keeping a narrow, period-appropriate profile for a small-displacement Italian car. Available choices are largely blackwall radials and include series such as Firestone F560 Radial, Michelin X, Michelin XAS, Michelin XAS-FF, Avon CR6ZZ, Vredestein Snow Classic, and Vredestein Sprint Classic. It is a useful size for owners who want radial construction without moving away from the car's original overall character.
560-15 is a numeric bias-ply size in which 5.60 refers to the tire's nominal section width in inches and 15 identifies the rim diameter. For the 1964 Alfa Romeo 1600, it represents the traditional bias-ply fitment path and preserves the visual character many restoration-minded owners want from a 1960s Alfa. This size is available in blackwall, narrow whitewall, and wide whitewall treatments from brands including Firestone, US Royal, and Coker Classic, with a Pro-Trac Front Runner also offered in the same sizing. It deserves a close look when maintaining a vintage appearance matters as much as road use.
Fitment is straightforward across the covered 1964 Alfa Romeo 1600 sub-model range because the same two tire-size paths appear throughout. Checking the exact sub-model still matters, but the main decision remains whether the car is being kept on a traditional 560-15 bias-ply setup or fitted with a 155R15 radial.

1964 Alfa Romeo 1600 Base,TI, Super, GT & Spider
The 1964 Alfa Romeo 1600 Base,TI, Super, GT & Spider grouping uses the same two fitment directions: 560-15 bias-ply or 155R15 radial on 15-inch rims. That means tire selection is less about separating trims and more about choosing the construction, appearance, and driving character that best match the car's current setup and intended use.
Bias-Ply to Radial Tire Conversion for the 1964 Alfa Romeo 1600
For the original 560-15 size, two radial-equivalent options are available. 155R15 serves as the 80-series metric radial equivalent, while 560R15 is the bias-look radial equivalent. The first follows a Euro-metric radial sizing convention, and the second is aimed at preserving a more traditional visual presentation. A recommended rim-width range of 4 to 5 inches applies to these equivalent considerations, and any change from 560-15 should still be checked against actual wheel width, overall vehicle setup, and clearance.

Best 1964 Alfa Romeo 1600 Tires for Sale
Available 1964 Alfa Romeo 1600 tire choices cover both 155R15 radials and 560-15 bias-ply designs, with brands including Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. The main comparison points are construction, tire series, and whether a blackwall, narrow whitewall, or wide whitewall presentation suits the car.
These 1964 Alfa Romeo 1600 tire FAQs focus on the two fitment paths for this car: 560-15 bias-ply and 155R15 radial. They also cover rim fitment, radial equivalents, appearance choices, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 1964 Alfa Romeo 1600?
The 1964 Alfa Romeo 1600 uses two recognized tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both are 15-inch tire sizes, but they represent different sizing systems and different ownership approaches, with the bias-ply size leaning toward a traditional vintage presentation and the radial size reflecting a more modern construction style.
Selecting between them starts with confirming how the car is currently set up and what kind of driving or restoration goal is in mind. A car already on correct-width 15-inch wheels may support either path, but wheel width, suspension condition, and clearance should still be checked before changing from one construction type or size convention to the other.
What size rim does a 1964 Alfa Romeo 1600 use?
The tire sizes associated with the 1964 Alfa Romeo 1600 both use a 15-inch rim diameter. That applies to the 560-15 bias-ply fitment and the 155R15 radial fitment, so the wheel diameter remains consistent even though the tire constructions and sizing formats differ.
Rim diameter is only the first step, because wheel width still matters when choosing among available tires. Many 155R15 radial options are intended for relatively narrow wheels, and the 560-15 bias-ply choices also have their own rim-width expectations. Measuring the actual wheel on the car is worthwhile, especially if the Alfa has been restored, modified, or fitted with replacement wheels over the years.
Do all 1964 Alfa Romeo 1600 sub-models use the same tire size?
The covered 1964 Alfa Romeo 1600 Base, TI, Super, GT, and Spider configurations share the same two tire-size paths: 560-15 bias-ply and 155R15 radial. That makes sub-model fitment more consistent than on vehicles where different trims use different wheel diameters or separate tire sizes.
Even with that shared fitment, the final choice still depends on the car in front of you. A restoration-oriented GT or Spider may call for one visual approach, while a frequently driven sedan may benefit from another. Verifying the actual wheel width and the current tire construction on the car helps keep the selection aligned with both appearance and practical use.
Bias-Ply & Radial Options
Is 560-15 a bias-ply or radial tire for the 1964 Alfa Romeo 1600?
560-15 is the bias-ply tire size associated with the 1964 Alfa Romeo 1600. It uses the older numeric sizing format common to many vintage cars, where the first number reflects nominal section width in inches and the final number identifies the 15-inch wheel diameter.
That matters because a 560-15 bias-ply does not represent the same construction as a 155R15 radial, even though both fit a 15-inch rim. Owners choosing 560-15 are often prioritizing traditional appearance and vintage tire character, while anyone considering a radial alternative should compare wheel width, overall setup, and clearance before making the change.
What radial tire sizes are equivalent to 560-15?
Two radial-equivalent sizes are associated with 560-15. The first is 155R15, which is the 80-series metric radial equivalent, and the second is 560R15, which is the bias-look radial equivalent. Those two options give the 1964 Alfa Romeo 1600 owner a choice between a conventional Euro-metric radial format and a radial intended to keep a more traditional visual impression.
A recommended rim-width range of 4 to 5 inches accompanies those equivalent-size considerations. Even so, equivalent does not mean automatic interchangeability. Wheel width, tire-to-body clearance, and the car's actual suspension and steering setup should all be reviewed before replacing a 560-15 bias-ply with either radial option.
Can I use a bias-look radial on a 1964 Alfa Romeo 1600?
A bias-look radial equivalent is available for the 1964 Alfa Romeo 1600 in size 560R15. It serves as a radial alternative for the original 560-15 bias-ply size while aiming to preserve a more vintage-looking tire presentation than a modern metric radial typically provides.
That makes it especially relevant for owners trying to balance appearance with radial construction. The recommended rim-width range tied to the 560-15 equivalent path is 4 to 5 inches, and it is still wise to confirm wheel width, body clearance, and overall stance before switching. A visually traditional tire can still alter fitment needs if the wheel or chassis setup has changed.
Choosing the Right Tire
What should I consider when choosing a 1964 Alfa Romeo 1600 tire?
Start with the main decision this Alfa presents: 560-15 bias-ply or 155R15 radial. Both fit a 15-inch rim, but they lead to different outcomes in construction, appearance, and driving character. After that, look at wheel-width compatibility, the car's current setup, and whether the goal is a traditional restoration-style presentation or a radial-equipped road car.
Product differences matter once size and construction are settled. In 155R15, the choices include several blackwall radial series from Firestone, Michelin, Avon, and Vredestein. In 560-15, the range expands into blackwall, narrow whitewall, and wide whitewall bias-ply tires from Firestone, US Royal, and Coker Classic. Matching the tire to the car's visual style is just as important as matching the size.
What sidewall styles are available for 1964 Alfa Romeo 1600 tires?
Sidewall style depends on which tire size and construction path you choose for the 1964 Alfa Romeo 1600. The 155R15 radial offerings are blackwall tires, while the 560-15 bias-ply range includes blackwall, narrow whitewall, and wide whitewall options. That creates a noticeable difference in how the car can be presented.
A blackwall radial typically suits an understated sporting look, especially on an Alfa coupe or sedan driven regularly. Whitewall choices in 560-15 move the car toward a more restoration-oriented or period-style appearance. Because sidewall treatment can change the visual balance of a small 1960s Italian car, it helps to choose a style that complements the wheel, trim, and intended character of the vehicle.
What brands offer tires for the 1964 Alfa Romeo 1600?
Several brands cover the tire sizes used on the 1964 Alfa Romeo 1600. In 155R15 radial, available brands include Firestone, Michelin, Avon, and Vredestein. In 560-15 bias-ply, choices include Firestone, US Royal, Coker Classic, and Pro-Trac, giving the owner a broad mix of traditional and radial-oriented options.
Brand alone should not drive the decision. It makes more sense to compare the correct size first, then look at construction, rim-width suitability, tire series, and sidewall presentation. A Michelin XAS and a Firestone F560 Radial serve different tastes within the same 155R15 size, just as a blackwall 560-15 creates a different effect than a wide-white bias-ply.
Restoration & Appearance
Which tire should I choose for a period-style 1964 Alfa Romeo 1600?
For a period-style 1964 Alfa Romeo 1600, the 560-15 bias-ply size is the most traditional starting point. It preserves the older numeric sizing format and is available in blackwall, narrow whitewall, and wide whitewall treatments, which gives the car a distinctly vintage presentation that many restoration-minded owners find appealing.
The exact look still depends on how the specific car is being restored. A subtle blackwall may suit a sporting European feel, while a whitewall changes the visual character significantly. When exact originality matters, it is worth checking period photography, marque-club guidance, and vehicle-specific historical references before settling on a sidewall treatment or brand.
How does tire construction affect the appearance of a restored 1964 Alfa Romeo 1600?
Tire construction changes the visual impression of a restored 1964 Alfa Romeo 1600 more than many owners expect. A 560-15 bias-ply typically gives the car a more vintage stance and sidewall look, while a 155R15 radial keeps the size narrow but presents the car with a more modern construction style and a blackwall-only appearance in the available product range.
That difference can influence whether the finished car feels more restoration-oriented or more road-use oriented. A bias-look radial such as 560R15 may also appeal to owners who want a traditional appearance with radial construction. The best choice depends on whether the restoration priority is visual authenticity, driving use, or a compromise between the two.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1964 Alfa Romeo 1600?
Yes, modifications can affect tire fitment on a 1964 Alfa Romeo 1600 even when the nominal tire size is correct. Replacement wheels, altered wheel width, suspension changes, lowered ride height, brake upgrades, or bodywork variations can all change how a 560-15 or 155R15 tire sits in the car's wheel openings and steering range.
That is especially important on compact vintage cars where clearance margins can be tighter than expected. Any Alfa fitted with aftermarket wheels or chassis changes should be checked for wheel diameter, actual rim width, inner and outer clearance, and steering travel before new tires are installed. A correct size on paper still needs to suit the car's present configuration.
What should I inspect before driving a 1964 Alfa Romeo 1600 on new tires?
Before driving a 1964 Alfa Romeo 1600 on new tires, inspect the wheels for correct diameter and condition, confirm that lug hardware and seating surfaces are proper, and make sure the tires are inflated appropriately for the setup being used. It is also smart to verify that the new tires clear the suspension, fenders, and steering components through full movement.
A short initial road test is worthwhile after installation. Listen for rubbing, check for pulling or vibration, and recheck air pressure after the first miles. Vintage cars that have sat for long periods deserve extra attention to wheel bearings, alignment condition, and suspension wear, since new tires can quickly reveal issues that older worn tires may have masked.
How should 560-15 or 155R15 tires on a collector 1964 Alfa Romeo 1600 be maintained?
Collector-car tires on a 1964 Alfa Romeo 1600 should be maintained with regular pressure checks, visual inspection, and careful storage habits. Look for cracking, bulges, cuts, irregular tread wear, and signs of air loss whether the car is on 560-15 bias-ply tires or 155R15 radials. Low annual mileage does not prevent aging, so condition matters as much as tread depth.
Storage environment has a real effect on long-term tire health. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve sidewalls and rubber compounds. It also helps to move the car periodically or support it properly during long storage so the tires are not left under the same load in one position for months at a time.
