The 1962 Fiat 1100 sits in the sweet spot of postwar European small-car design, offering practical family transportation with the tidy proportions and light road manners that made Italian sedans and wagons so appealing in period. Tire choice on this Fiat depends first on body configuration, because sedan and Export & Speciale models use 155R14 radial or 520-14 bias-ply sizing, while wagon and Familiare variants use 165R14 radial or 560-14 bias-ply sizing. That creates a meaningful choice between traditional bias-ply presentation and more modern radial construction, along with blackwall, narrow whitewall, and wide whitewall options in certain sizes. The right selection comes down to matching the exact sub-model, preserving the look you want, and confirming wheel compatibility before changing construction.
Which Tire Size Is Right for The 1962 Fiat 1100
The 1962 Fiat 1100 uses four primary tire sizes, and the right one depends on the specific sub-model rather than rim diameter, since all of them are built around a 14-inch wheel. Sedan and Export & Speciale versions use smaller 155R14 radial or 520-14 bias-ply sizing, while Wagon and Familiare models step up to 165R14 radial or 560-14 bias-ply sizing. The first job is confirming the exact model, then deciding whether you want radial road manners or a more traditional bias-ply look.
155R14 is a Euro-metric radial size in which 155 identifies the nominal section width in millimeters, R denotes radial construction, and 14 is the rim diameter in inches. On the 1962 Fiat 1100, this size serves sedan-based applications that use a radial tire rather than a vintage numeric bias-ply. Available choices include blackwall radials from Michelin and Firestone in series such as Michelin X Radial and F560 Radial. It is a strong reference point for owners who want a more modern radial format while keeping the car on the correct 14-inch wheel size.
520-14 is a numeric bias-ply size, with 5.20 representing the nominal section width in inches and 14 indicating the wheel diameter. This is the traditional bias-ply fitment used on certain 1962 Fiat 1100 sedan-based models, making it especially relevant for buyers who want a more period-style tire construction. In this size, the emphasis is on appearance as much as fitment, with Premium Sport Lowrider options centered on narrow whitewall treatments. It is the size to evaluate when preserving a vintage presentation matters more than moving to a radial tire format.
165R14 is a Euro-metric radial size that uses a 165-millimeter nominal section width, radial construction, and a 14-inch rim diameter. On the 1962 Fiat 1100, this larger radial size belongs to wagon-style applications rather than the smaller sedan-based fitment. Blackwall choices are available from Pirelli, Michelin, and Vredestein across series such as Cinturato CA67, Michelin XAS, and Sprint Classic. It is the right place to focus when your Fiat uses the wagon or Familiare setup and you want radial construction with several distinct brand and series options.
560-14 is a numeric bias-ply size, meaning a nominal 5.60-inch section width on a 14-inch wheel. For the 1962 Fiat 1100, this is the bias-ply counterpart used on wagon-oriented configurations that do not use the narrower 520-14 size. BFGoodrich offers this fitment in the Silvertown Classic Bias Ply line with blackwall, narrow whitewall, and wide whitewall styles, giving the buyer several different visual directions. It is the size to review when a traditional bias-ply construction and a restoration-oriented sidewall treatment are part of the goal.
Fitment varies by sub-model on the 1962 Fiat 1100, even though every version uses a 14-inch rim. Confirming whether the car is a Sedan, Wagon, Export & Speciale, or Familiare is the key step, because that determines both the primary tire size family and the bias-ply-versus-radial decision.

1962 Fiat 1100 D Sedan
The 1962 Fiat 1100 D Sedan uses the smaller sedan-size fitment family, with a choice between 155R14 radial and 520-14 bias-ply construction. That gives the owner a clear decision between a modern radial format and a more traditional bias-ply presentation before narrowing the choice by brand or sidewall style.
The 1962 Fiat 1100 D Wagon uses the larger wagon-size fitment family, pairing 165R14 radial sizing with 560-14 bias-ply alternatives. Tire selection starts with construction preference, then moves to details such as blackwall versus whitewall appearance and wheel-width compatibility within the 14-inch setup.
The 1962 Fiat 1100 Export & Speciale follows the same tire-size pattern as the sedan-style configuration, using 155R14 in radial form or 520-14 in bias-ply form. That makes the choice less about size uncertainty and more about whether the car is being equipped for period-style appearance or radial road use.
The 1962 Fiat 1100 Familiare shares the wagon-oriented fitment pattern, using 165R14 radial sizing or 560-14 bias-ply sizing on 14-inch rims. Buyers should start by confirming the existing wheel setup, then choose between a traditional bias-ply look and the broader radial product selection offered in this larger size.
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.

Tire Size & Fitment
What tire size fits a 1962 Fiat 1100?
A 1962 Fiat 1100 can use 155R14 or 520-14 on the D Sedan and Export & Speciale, while the D Wagon and Familiare use 165R14 or 560-14. The radial sizes are 155R14 and 165R14, and the bias-ply sizes are 520-14 and 560-14. All of these fitments are built around a 14-inch rim.
The important step is matching the tire to the exact sub-model, not just the year and model name. Sedan-based and wagon-based versions do not share the same size family, so checking the body style and existing wheel setup helps avoid choosing a tire that is correct for a different 1100 variant.
What size rim does a 1962 Fiat 1100 use?
The 1962 Fiat 1100 uses a 14-inch rim diameter across its supported tire sizes. That holds true whether the car is equipped with 155R14, 520-14, 165R14, or 560-14. The size change across sub-models is in tire width and construction choice, not in moving to a different wheel diameter.
Rim diameter is only the first check, because wheel width also matters when comparing specific tires. Before selecting a bias-ply or radial option, confirm that the wheels on the car are still the intended 14-inch units and have not been replaced with aftermarket wheels that change width or tire clearance.
Do all 1962 Fiat 1100 sub-models use the same tire size?
No, the 1962 Fiat 1100 uses two different size families depending on sub-model. The D Sedan and Export & Speciale use 155R14 radial or 520-14 bias-ply sizing, while the D Wagon and Familiare use 165R14 radial or 560-14 bias-ply sizing. All of them use 14-inch rims, but the tire sizes are not the same.
That difference matters because a tire that suits one 1100 configuration may not be the right choice for another. Owners should identify the exact body style first, then decide whether to stay with a traditional bias-ply construction or move toward the radial options available for that specific sub-model.
Bias-Ply & Radial Options
Is 520-14 a bias-ply or radial tire for the 1962 Fiat 1100?
520-14 is a bias-ply tire size on the 1962 Fiat 1100. It is used on the D Sedan and Export & Speciale, where it serves as the traditional numeric bias-ply fitment alongside the radial-size alternative of 155R14. The 520-14 format reflects an older sizing convention commonly associated with vintage tire construction.
Choosing 520-14 usually means prioritizing period-style appearance and keeping the car in a more traditional tire format. Before making that choice, confirm that the car is one of the sedan-based variants and that the wheels suit the intended tire's rim-width requirements rather than assuming every 14-inch Fiat wheel is the same.
Should I use bias-ply or radial tires on a 1962 Fiat 1100?
That depends on the sub-model and on what you want from the car. Sedan-based versions can use either 155R14 radial or 520-14 bias-ply sizing, while wagon-based versions can use either 165R14 radial or 560-14 bias-ply sizing. Bias-ply keeps a more traditional construction, while the radial options use a later-style metric format.
The practical choice often comes down to appearance goals, driving habits, and wheel compatibility. A restoration-oriented owner may prefer the visual character of a bias-ply tire, while a road-use buyer may lean toward the radial options. Either way, check wheel width, clearance, and the actual sub-model before changing construction type.
What should I check before converting my 1962 Fiat 1100 from bias-ply to radial tires?
Start by confirming which sub-model you have, because the radial size depends on it. A D Sedan or Export & Speciale uses 155R14 as the radial choice in place of 520-14 bias-ply sizing, while a D Wagon or Familiare uses 165R14 instead of 560-14. All of those options stay on a 14-inch rim.
Wheel width, tire clearance, and the car's current setup should be reviewed before making the change. It also helps to inspect steering and suspension condition on an older Fiat, especially if the car has sat for long periods or has been modified, since radial conversion should be evaluated against the actual vehicle rather than the catalog size alone.
Choosing the Right Tire
What should I consider when choosing a 1962 Fiat 1100 tire?
The first consideration is the exact sub-model, because sedan-based and wagon-based 1962 Fiat 1100 variants do not share the same size family. After that, decide whether the car should stay with a traditional bias-ply construction or move to one of the available radial sizes. All supported fitments use 14-inch rims, but the tire sizes and product choices differ.
Once the size and construction are settled, compare the details that affect appearance and wheel compatibility. Some sizes are offered only in blackwall, while others include narrow or wide whitewall styling. Brand, tire series, and published rim-width ranges are also useful checkpoints when the goal is to match the Fiat's use, look, and wheel setup.
What sidewall styles are available for 1962 Fiat 1100 tires?
Sidewall choices for the 1962 Fiat 1100 include blackwall, narrow whitewall, and wide whitewall, depending on tire size. The radial sizes shown for 155R14 and 165R14 are offered as blackwalls, while the bias-ply sizes add more visual variety. In 520-14, the available options center on narrow whitewall styling, and 560-14 includes blackwall, narrow whitewall, and wide whitewall versions.
That makes sidewall selection part of the overall character of the car, not just a finishing detail. A buyer aiming for a simple touring look may prefer blackwalls, while a more decorative restoration style may lean toward whitewalls. The key is choosing the sidewall treatment within the correct size for the specific Fiat 1100 sub-model.
What brands offer tires for the 1962 Fiat 1100?
Tires for the 1962 Fiat 1100 are available from Michelin, Firestone, Pirelli, Vredestein, Premium Sport, and BFGoodrich. Brand choice depends on the tire size and construction you need, since the radial sizes and bias-ply sizes do not share the same product lineup. Some sizes have a broad radial selection, while others focus on vintage-style bias-ply offerings.
The better comparison is not brand alone but how each brand appears within the correct size, series, and sidewall style. Once the right sub-model fitment is confirmed, compare whether the tire is radial or bias-ply, whether it is blackwall or whitewall, and whether its wheel-width specification matches the Fiat's actual wheel setup.
Restoration & Appearance
Which tire should I choose for a period-style 1962 Fiat 1100?
A period-style 1962 Fiat 1100 usually starts with the correct bias-ply size for the sub-model. Sedan-based versions use 520-14 as the traditional bias-ply option, while wagon-based versions use 560-14. Those sizes preserve the older numeric format and offer the kind of visual character many restoration-minded owners want from a small Italian car of this era.
The final choice depends on how closely the car is being restored and what look suits it best. Sidewall treatment can noticeably change the presentation, especially where narrow or wide whitewalls are offered. If exact originality matters, compare the selected size and style against marque-club references or period photos for the specific Fiat configuration.
How does tire construction affect the appearance of a restored 1962 Fiat 1100?
Tire construction changes the visual tone of a restored 1962 Fiat 1100 almost as much as it changes the driving feel. Bias-ply options such as 520-14 and 560-14 give the car a more traditional vintage presentation, while 155R14 and 165R14 radials introduce a later-style metric format and a simpler blackwall appearance in the available choices.
That means the tire decision should support the restoration goal rather than being treated as a purely mechanical replacement. A buyer chasing a more authentic-looking period impression may gravitate toward the bias-ply sizes, while someone building a road car may accept the radial look. The important thing is keeping the correct size family for the exact sub-model.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1962 Fiat 1100?
Yes, modifications can change tire fitment on a 1962 Fiat 1100 even when the tire size itself is correct for the sub-model. Aftermarket wheels, altered wheel width, suspension changes, or body and fender work can affect how a 155R14, 520-14, 165R14, or 560-14 tire sits on the car. A 14-inch rim alone does not settle the fitment question.
Owners should compare the current wheel and suspension setup with the tire they plan to use, especially on cars that have been restored or personalized over time. Steering clearance, fender room, and the actual wheel width are all worth checking before mounting a new set, particularly when switching between bias-ply and radial construction.
What should I inspect before driving a 1962 Fiat 1100 on new tires?
Before driving a 1962 Fiat 1100 on new tires, inspect the wheels for damage or excessive corrosion, confirm the wheel size and width, and make sure the tires are mounted in the correct sub-model fitment. It is also wise to look over valve stems, lug hardware, and basic suspension and steering condition on a car of this age.
A short clearance check at full steering lock can help catch rubbing before road use. After the first miles, recheck inflation pressure and look for any signs of uneven contact, air loss, or interference. On an older collector Fiat, careful initial inspection matters as much as the tire choice itself.
How should tires on a collector 1962 Fiat 1100 be maintained?
Tires on a collector 1962 Fiat 1100 should be inspected regularly for cracking, bulges, cuts, uneven wear, and loss of air pressure, even if the car is driven only occasionally. Collector vehicles often age their tires through storage as much as through mileage, so condition matters more than tread depth alone on a lightly used Fiat.
Storage habits make a real difference. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and periodic movement can reduce flat-spotting during long rests. Before any longer outing, verify pressure and give the tires and wheels a close visual inspection rather than assuming a low-mileage set is road-ready.
