The 1971 Fiat 128 arrived at a pivotal moment for small European cars, bringing front-wheel-drive packaging and crisp, efficient design to buyers who wanted practical transportation with lively road manners. That compact, lightweight character makes tire choice especially important, because the car responds noticeably to size, profile, and construction. For this exact model year, the Fiat 128 uses 145R13 and 155R13 radial tire fitments on 13-inch rims. Available choices stay true to that classic Euro-metric radial character, with blackwall options from brands such as Michelin, Firestone, and Dunlop. The key is confirming the size that suits your specific car and balancing road use, appearance, and wheel compatibility.
Which Tire Size Is Right for The 1971 Fiat 128
The 1971 Fiat 128 uses two primary tire sizes, both in radial construction and both built for 13-inch rims. Because Sedan & Sport L Coupe and Wagon models can use either 145R13 or 155R13, the main decision is not construction type but choosing the size and tire character that best match your wheel width, desired stance, and intended road use.
A 145R13 is a Euro-metric radial with a nominal section width of 145 millimeters, radial construction, and a 13-inch rim diameter. In this format, the aspect ratio is not stated in the size itself, though it is commonly associated with an 80-series profile. For the 1971 Fiat 128, this size is available in blackwall form from Michelin and Firestone, including classic series such as Michelin XAS-FF and Firestone F560 Radial. It is a strong period-style choice for owners who want a traditional narrow radial presentation on the correct rim diameter.
A 155R13 follows the same Euro-metric radial sizing convention, but with a nominal section width of 155 millimeters on a 13-inch rim. That makes it a wider companion size within the same basic radial family used on the 1971 Fiat 128. Available blackwall options include Michelin XAS-FF and Dunlop SP Sport Aquajet, giving the buyer a choice between distinct vintage-oriented tire lines. This size is worth considering when the car is already set up for 155R13 tires and the wheel width and overall clearance support that wider fitment.
Fitment is relatively straightforward because both covered 1971 Fiat 128 sub-model groups can use the same two radial tire sizes. Checking the exact sub-model still matters, since the final choice between 145R13 and 155R13 should be matched to the car’s wheel setup and the look or road feel you want.

1971 Fiat 128 Sedan & Sport L Coupe
The 1971 Fiat 128 Sedan & Sport L Coupe can use either 145R13 or 155R13 radial tires on 13-inch rims. That gives owners room to choose a narrower or wider classic Euro-metric radial while still keeping the selection centered on proper wheel compatibility and a vintage-appropriate presentation.
The 1971 Fiat 128 Wagon also uses the same 145R13 and 155R13 radial fitment family. Tire selection comes down to confirming which size is on the car now, checking wheel width, and choosing the tire line that best suits restoration-minded use or regular vintage driving.
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.

The product grid lets you compare classic series such as Michelin XAS-FF, Firestone F560 Radial, and Dunlop SP Sport Aquajet, along with useful differences in rim-width specification and load details where stated.
These 1971 Fiat 128 tire FAQs focus on the two 13-inch radial sizes, how sub-model fitment works, how to compare the available blackwall tire options, and what to inspect before putting a vintage Fiat back on the road.
Tire Size & Fitment
What tire size fits a 1971 Fiat 128?
The 1971 Fiat 128 uses two primary tire sizes: 145R13 and 155R13. Both are radial tires built for 13-inch rims, and both appear across the covered Fiat 128 sub-models for this model year.
That means the real fitment question is deciding which of those two sizes belongs on your particular car as it sits today. Checking the tires already on the vehicle, confirming wheel width, and looking for any past wheel or suspension changes will help narrow the choice before selecting a replacement.
What size rim does a 1971 Fiat 128 use?
Both primary tire sizes for the 1971 Fiat 128, 145R13 and 155R13, are built around a 13-inch rim diameter. The wheel diameter is consistent even though the car can use two different tire widths.
Rim diameter is only the first part of the check. Wheel width still matters, especially when moving between a 145R13 and a 155R13, so it is smart to confirm the actual wheel on the car rather than assuming every 13-inch wheel is equally suitable for both sizes.
Do all 1971 Fiat 128 sub-models use the same tire size?
The covered 1971 Fiat 128 sub-models share the same two tire sizes rather than using completely different fitment families. Both the Sedan & Sport L Coupe and the Wagon can use 145R13 or 155R13 radial tires.
That shared fitment makes shopping easier, but it does not eliminate the need to verify the actual setup on the car. A Fiat 128 that already wears one size, has different wheel widths, or has been changed over the years may point you more clearly toward one of the two available sizes.
Choosing the Right Tire
What should I consider when choosing a 145R13 or 155R13 tire for a 1971 Fiat 128?
Start with the correct size for the car’s current wheel setup, then compare the tire line itself. On a 1971 Fiat 128, both 145R13 and 155R13 are radial fitments, so the main differences come from width, brand, tire series, and supporting specifications such as stated rim-width range or load information.
A narrower 145R13 keeps the selection close to a traditional small-car presentation, while a 155R13 moves into a wider version of the same classic Euro-metric radial family. Matching the tire to the wheel, intended use, and visual goal will usually matter more than simply choosing the larger of the two sizes.
What sidewall styles are available for 1971 Fiat 128 tires?
The available tire choices for the 1971 Fiat 128 are blackwall radials in both 145R13 and 155R13. That keeps the appearance clean and understated, which suits the compact European character of the Fiat 128 well.
Since the visible sidewall treatment does not vary here, the appearance decision shifts to the tire series itself and to the size you choose. Buyers focused on a restoration-minded look should compare how a narrower 145R13 versus a wider 155R13 complements the car’s stance and wheel proportions.
What brands offer tires for the 1971 Fiat 128?
Michelin, Firestone, and Dunlop all offer applicable tires for the 1971 Fiat 128. Michelin appears in both 145R13 and 155R13, while Firestone is available in 145R13 and Dunlop appears in 155R13.
Brand alone should not decide the purchase. It is better to compare the exact size you need, the tire series, the stated rim-width range when given, and any load information included with the product. Those details help you choose a tire that matches both the car’s setup and your driving expectations.
Restoration & Appearance
Which tire should I choose for a period-style 1971 Fiat 128?
A period-style 1971 Fiat 128 tire choice starts with the correct 13-inch radial family and then narrows to 145R13 or 155R13 depending on the car’s existing setup. Both sizes preserve the classic Euro-metric look better than drifting into unrelated modern sizing conventions.
For many restoration-minded owners, the decision comes down to how narrow or full the tire should look on the wheel and whether the selected series matches the character of the car. If exact originality matters, compare the tire choice against marque references, surviving examples, and other vehicle-specific historical guidance.
How does tire construction affect the appearance of a restored 1971 Fiat 128?
On a 1971 Fiat 128, construction is less of a visual fork than it is on many earlier American cars because the primary fitments are already radial. That means the restored appearance is shaped more by the Euro-metric size, the tire line, and the blackwall presentation than by choosing between bias-ply and radial.
Even within radial fitment, size still changes the look of the car. A 145R13 usually gives a slimmer, lighter visual impression, while a 155R13 has a fuller stance on the same 13-inch rim diameter. The better-looking choice is the one that matches the wheel and preserves balanced proportions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1971 Fiat 128?
Yes. A 1971 Fiat 128 may have been altered over the years with different wheels, suspension changes, or body adjustments, and those changes can affect whether 145R13 or 155R13 is the more appropriate fitment.
A car with aftermarket wheels should have its actual wheel diameter and width checked before replacement tires are chosen. Clearance at the fenders and steering components also matters, especially when moving from one width to the other, so the safest approach is to verify the car as it currently sits.
What should I inspect before driving a 1971 Fiat 128 on new tires?
Before driving a 1971 Fiat 128 on new tires, inspect the wheels for damage, confirm the wheel hardware is in good condition, and make sure the tire size matches the actual rim setup. It is also wise to look over alignment-related wear points and basic suspension condition.
Once the tires are mounted, check inflation, sidewall clearance, and steering clearance at full lock. A short initial drive can reveal rubbing, vibration, or pull that should be corrected early. On a lightweight vintage car, those basic checks go a long way toward making the new tires feel settled and predictable.
How should 145R13 or 155R13 tires on a collector 1971 Fiat 128 be maintained?
Collector-car tires on a 1971 Fiat 128 should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Even when tread looks good, a low-use vintage car can still develop age-related issues such as sidewall cracking, flat spotting, or air loss.
Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the rubber over time. It also pays to inspect the tires before each outing rather than waiting for seasonal service, since a stored Fiat 128 may sit long enough for condition changes to go unnoticed between drives.
