The 1975 Alfa Romeo Alfetta sits in an era when Alfa was blending sporting sedan character with distinctly European road manners, and that makes tire choice especially important today. Buyers looking at one of these cars are usually balancing originality of stance and steering feel against practical modern road use. This model uses radial tires, with 165R14 and 185/70R14 fitments depending on sub-model, both on 14-inch wheels. That opens the door to several authentic-looking blackwall choices, along with a whitewall option in 185/70R14 for a different visual treatment. The key step is confirming whether the car is a Berlina or a GT & Berlina SD before narrowing the tire selection.
Which Tire Size Is Right for The 1975 Alfa Romeo Alfetta
The 1975 Alfa Romeo Alfetta uses two primary tire sizes, and the correct one depends on the specific sub-model. Both are radial tires for 14-inch rims, so the first job is identifying whether the car is a Berlina or a GT & Berlina SD. Once that is confirmed, the decision shifts to selecting the right tire character within that size, including brand, series, sidewall style, and rim-width compatibility.
165R14 is a Euro-metric radial size in which 165 refers to nominal section width in millimeters, R indicates radial construction, and 14 is the wheel diameter in inches. In this format, the aspect ratio is not stated, and it is commonly associated with an 80-series profile. On the 1975 Alfa Romeo Alfetta, this size supports a traditional European fitment approach and is available in blackwall form from Pirelli, Michelin, and Vredestein across Cinturato CA67, XAS, and Sprint Classic lines. It is the right size to evaluate when preserving the narrower original-style presentation used on the Berlina.
185/70R14 is a metric radial size that spells out more of the tire's dimensions, with 185 as nominal section width in millimeters, 70 as the aspect ratio, R for radial construction, and 14 for rim diameter. For the 1975 Alfa Romeo Alfetta, this is the fitment tied to the GT & Berlina SD configuration rather than every Alfetta variant. Available choices include blackwall tires from Avon, Dunlop, Michelin, and Vredestein, plus a wide whitewall BFGoodrich Silvertown Radial. This size is the one to compare when your car calls for a lower-profile 14-inch radial with broader product variety.
Sub-model fitment matters on the 1975 Alfa Romeo Alfetta because the covered versions do not all share the same tire size. Confirming whether the car is a Berlina or a GT & Berlina SD is the first step before comparing tire series, sidewall style, and wheel compatibility.

1975 Alfa Romeo Alfetta Berlina
The 1975 Alfa Romeo Alfetta Berlina uses the 165R14 radial size on a 14-inch rim. That keeps tire selection centered on traditional blackwall European-style options and makes period-style appearance a bigger consideration than deciding between multiple primary sizes.
The 1975 Alfa Romeo Alfetta GT & Berlina SD uses the 185/70R14 radial size on a 14-inch rim. This opens up a wider range of product choices, so the comparison becomes more about tire series, sidewall treatment, and confirming the wheel width already on the car.
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.
Best 1975 Alfa Romeo Alfetta Tires for Sale
Available 14-inch Alfetta tires span European-style blackwall radials from Pirelli, Michelin, Vredestein, Avon, and Dunlop, with the 185/70R14 size adding a wide whitewall BFGoodrich Silvertown Radial. Across both sizes, buyers can compare distinct tire series along with different rim-width specifications.
Common Alfetta tire questions usually come down to the correct size for the exact sub-model, what the 14-inch radial fitments mean, and how to choose among blackwall, whitewall, and European-series tire options for restoration or road use.
Tire Size & Fitment
What tire size fits a 1975 Alfa Romeo Alfetta?
A 1975 Alfa Romeo Alfetta uses either 165R14 or 185/70R14, depending on the sub-model. The Berlina uses 165R14, while the GT & Berlina SD uses 185/70R14. Both are radial tire fitments for 14-inch wheels, but they are not the same size and should not be treated as a universal match across all Alfetta versions.
The practical step is identifying the exact sub-model before choosing a tire. After that, confirm the wheel diameter already on the car and compare the tire's rim-width requirements with the wheels in use, especially if the car has had any wheel changes over the years.
What size rim does a 1975 Alfa Romeo Alfetta use?
The 1975 Alfa Romeo Alfetta uses 14-inch rims with both of its primary tire sizes. That applies to the 165R14 fitment used on the Berlina and the 185/70R14 fitment used on the GT & Berlina SD. The shared wheel diameter makes the main size difference one of tire width and profile rather than wheel diameter.
Wheel diameter is only part of the fitment picture, so it is still worth checking the actual wheel width on the car. Some available 14-inch tires have different rim-width ranges, and that becomes important if the Alfetta is wearing aftermarket wheels or replacement steel wheels from a previous owner.
Do all 1975 Alfa Romeo Alfetta sub-models use the same tire size?
No, the 1975 Alfa Romeo Alfetta does not use one tire size across all covered sub-models. The Berlina uses 165R14, while the GT & Berlina SD uses 185/70R14. Both are radial constructions, but the sizing formats are different and they serve different Alfetta configurations.
That means sub-model identification comes before any product comparison. Once the correct size is confirmed, the buyer can look at brand, series, sidewall style, and wheel-width suitability rather than trying to decide between two primary sizes that belong to different versions of the car.
Choosing the Right Tire
What should I consider when choosing a tire for a 1975 Alfa Romeo Alfetta?
Start with the correct primary size for the specific car: 165R14 for the Berlina or 185/70R14 for the GT & Berlina SD. Both are radial fitments on 14-inch wheels, so the next considerations are wheel-width compatibility, tire series, sidewall appearance, and the kind of driving the car will see.
A period-minded owner may lean toward traditional blackwall European tires such as Michelin XAS, Pirelli Cinturato CA67, or Vredestein Sprint Classic, while another buyer may simply want the right size with a different visual treatment. It also helps to compare load figures and overall wheel setup before making a final selection.
What sidewall styles are available for 1975 Alfa Romeo Alfetta tires?
Blackwall is the main sidewall style available for the 1975 Alfa Romeo Alfetta in both 165R14 and 185/70R14. In 185/70R14, there is also a wide whitewall option in the BFGoodrich Silvertown Radial. That makes blackwall the traditional-looking choice, with whitewall available only in the larger Alfetta fitment.
Sidewall appearance changes the car's presentation even when the tire size stays correct. A blackwall usually suits the European sporting character of the Alfetta, while a whitewall creates a different visual effect and should be chosen as an appearance preference rather than as an assumption about original delivery.
What brands offer tires for the 1975 Alfa Romeo Alfetta?
Tires for the 1975 Alfa Romeo Alfetta are available from Pirelli, Michelin, Vredestein, BFGoodrich, Avon, and Dunlop, depending on size. The 165R14 fitment includes Pirelli Cinturato CA67, Michelin XAS, and Vredestein Sprint Classic, while 185/70R14 adds BFGoodrich Silvertown Radial, Avon CR6ZZ, and Dunlop Sport Classic.
Brand alone is not the whole decision, because the available choices also differ by tire series, sidewall treatment, and rim-width range. Once the correct Alfetta sub-model and tire size are confirmed, compare the tire's intended look and wheel compatibility instead of assuming every 14-inch radial serves the same role.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Alfa Romeo Alfetta?
A period-style 1975 Alfa Romeo Alfetta starts with using the correct sub-model tire size, then selecting a tire that preserves a traditional European radial look. For the Berlina, that means 165R14, while the GT & Berlina SD uses 185/70R14. Blackwall options such as Michelin XAS, Pirelli Cinturato CA67, and Vredestein Sprint Classic suit that approach well.
Appearance should be considered alongside wheel fitment and intended use. Owners pursuing exact originality may want to cross-check marque references or restoration documentation, since a period-style tire is not automatically the same thing as the exact brand or sidewall presentation delivered when the car was new.
How does tire construction affect the appearance of a restored 1975 Alfa Romeo Alfetta?
Construction is simpler on the 1975 Alfa Romeo Alfetta because the primary fitments are already radial rather than bias-ply. That means the visual difference comes less from construction type and more from size format, tread character, tire series, and sidewall treatment. In practical terms, blackwall 165R14 and 185/70R14 tires keep the car closer to a traditional European presentation.
The BFGoodrich wide whitewall in 185/70R14 creates a noticeably different look, even though it remains the correct basic size category for that sub-model. A restored Alfetta can look quite different depending on sidewall choice, so the tire should support the car's intended character rather than simply filling the wheel opening.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Alfa Romeo Alfetta?
Yes, modifications can change how a tire works on a 1975 Alfa Romeo Alfetta even when the nominal size appears correct. Aftermarket wheels, different wheel widths, altered offsets, suspension changes, or body modifications can all affect clearance and compatibility. That matters with both 165R14 and 185/70R14 because each tire size has its own wheel-width considerations.
A modified Alfetta should be checked at the wheel, not just by reading the sidewall. Verify actual rim diameter and width, then inspect steering, fender, and suspension clearance through the full range of movement before settling on a tire choice for regular road use.
What should I inspect before driving a 1975 Alfa Romeo Alfetta on new tires?
Before road use, inspect the 1975 Alfa Romeo Alfetta's wheels for correct diameter and condition, confirm that the tires match the car's sub-model size, and check for proper inflation. It is also wise to look over the suspension, steering components, and alignment condition so the new tires are not immediately affected by existing wear.
A short collector-car shakedown often reveals issues that do not show up while the car is parked. Listen for rubbing, feel for pull or vibration, and recheck pressure after the first drives. Older cars that sit for long periods deserve extra attention to wheel hardware, valve stems, and signs of air loss.
How should tires on a collector 1975 Alfa Romeo Alfetta be maintained?
Tires on a collector 1975 Alfa Romeo Alfetta should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and uneven wear, and driven often enough to avoid long-term flat spotting from extended storage. This matters whether the car uses 165R14 or 185/70R14, because age and inactivity can affect a collector tire as much as mileage does.
Storage conditions also play a major role in tire life. Keep the Alfetta away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment when possible, and give the tires a careful visual check before any longer drive, especially after the car has been parked for an extended period.
