The 1957 Lancia Flaminia arrived as Lancia’s new flagship, carrying the refined engineering and grand touring character that defined the marque in the postwar European luxury market. For owners today, tire selection is closely tied to that original Italian millimetric wheel tradition rather than a more familiar inch-based American sizing system. The 1957 Lancia Flaminia uses 165-400 and 165R400 radial tire sizing, both built around a 400mm rim format. Available choices center on Michelin millimetric radials, including blackwall and narrow whitewall presentations. That makes the key decision less about modern upsizing and more about preserving the proper look, wheel compatibility, and road manners for the car’s intended use.
Which Tire Size Is Right for The 1957 Lancia Flaminia
The 1957 Lancia Flaminia is associated with two closely related primary tire sizes, 165-400 and 165R400, and both are radial millimetric fitments tied to a 400mm wheel. Since the Flaminia Base is connected with both sizes, the first step is confirming exactly how the tire is marked on the car now and verifying the wheel itself before choosing between the available radial options.
165-400 is a classic millimetric tire size in which 165 identifies the nominal section width in millimeters and 400 refers to the wheel diameter in millimeters rather than inches. For the 1957 Lancia Flaminia, it represents a radial-format fitment aligned with the car’s European wheel standard. This size matters mainly because it points you toward the proper millimetric wheel family and away from assuming a common 15-inch or 16-inch American replacement. A Flaminia wearing this marking should have its wheel diameter confirmed carefully before any tire decision is made.
165R400 is a Euro-metric radial size that uses 165 as the nominal section width, R to designate radial construction, and 400 to indicate a 400mm rim diameter. On the 1957 Lancia Flaminia, this is the size supported by available Michelin products, including blackwall and narrow whitewall versions within the Michelin X Radial family. That gives owners a meaningful appearance choice while staying within the correct millimetric radial format. It is the size to evaluate closely when the goal is road use with a proper period-style presentation and correct wheel compatibility.
Sub-model fitment is straightforward here because the covered 1957 Lancia Flaminia Base is associated with the same millimetric radial sizing family. Even so, checking the exact tire marking on the car still matters, since the decision turns on wheel confirmation and product style rather than broad sub-model differences.

Tire Size & Fitment
What tire size fits a 1957 Lancia Flaminia?
The 1957 Lancia Flaminia is associated with two closely related radial sizes: 165-400 and 165R400. Both belong to the same millimetric fitment family and are built around a 400mm wheel standard rather than a conventional inch-based rim size.
That distinction is important because a 400mm wheel should not be treated like a common 15-inch wheel just because the sizes appear similar at a glance. The safest path is to read the tire marking already on the car, confirm the wheel size directly, and then choose a matching millimetric radial rather than trying to substitute by appearance alone.
What size rim does a 1957 Lancia Flaminia use?
The 1957 Lancia Flaminia uses a 400mm rim format with its millimetric radial tire sizing. That applies to the 165R400 products available for the car and aligns with the Flaminia’s European millimetric wheel tradition.
This is the key fitment check before ordering tires, because a 400mm wheel is a separate standard from inch-diameter wheels. Measuring the wheel or verifying its stamped marking helps avoid mismatch problems, and it is especially important on collector cars that may have had wheel changes or long periods of storage between tire replacements.
Does the 1957 Lancia Flaminia Base use the same tire size?
The 1957 Lancia Flaminia Base is associated with the same millimetric radial sizing family as the model core, using 165-400 and 165R400. There is no separate alternate inch-based primary fitment shown for the Base within this application.
That keeps sub-model selection fairly simple, but the exact tire marking still matters because product availability is centered on 165R400. A Base model owner should verify the wheel remains a 400mm millimetric rim and check the tire size currently mounted, especially if the car has been restored, imported, or fitted with replacement wheels at some point.
Choosing the Right Tire
What should I consider when choosing a 165R400 tire for a 1957 Lancia Flaminia?
Start with the core fitment points: 165R400 radial construction, 400mm rim diameter, and the wheel-width range that matches the tire you are considering. For the 1957 Lancia Flaminia, that means staying within the proper millimetric format rather than treating the car like a standard inch-rim application.
After that, the decision becomes one of presentation and usage. A narrow whitewall changes the car’s visual character, while a blackwall gives a more understated look. It also helps to compare the tire’s intended rim-width range against the wheels actually on the car, since collector vehicles sometimes carry replacement rims that differ from the original setup.
What sidewall styles are available for 1957 Lancia Flaminia tires?
The available 165R400 tires for a 1957 Lancia Flaminia include both blackwall and narrow whitewall sidewall styles. Those choices appear within Michelin’s millimetric radial offerings for this fitment.
Sidewall style is mainly an appearance decision once the correct size and wheel format are confirmed. A narrow whitewall suits an elegant period-style presentation, while a blackwall keeps the look simpler and more restrained. Either way, the sidewall treatment should be chosen after confirming the tire is correct for the 400mm wheel and the car’s intended use.
What brands offer tires for the 1957 Lancia Flaminia?
Michelin is the brand represented in the available 165R400 tire choices for the 1957 Lancia Flaminia. The options are part of the Michelin millimetric radial family and include more than one sidewall presentation.
Since the brand selection is narrow, the real comparison is between the specific Michelin offerings and their fitment details. Owners should look at sidewall style, rim-width range, and the exact product format that best matches the wheel and restoration goal. That approach is more useful than trying to compare the Flaminia against broader modern tire categories.
Restoration & Appearance
Which tire should I choose for a period-style 1957 Lancia Flaminia?
A period-style 1957 Lancia Flaminia tire choice starts with the correct millimetric radial fitment, centered on 165R400 for the available products. From there, the most visible difference is the sidewall presentation, with blackwall and narrow whitewall options giving the car a different visual tone.
The best selection depends on how the car is being presented. A restoration aimed at authentic era character may favor the sidewall style that matches the car’s known history, photos, or marque references, while a driver-focused restoration may simply choose the look that complements the car. The important part is preserving the correct millimetric format and wheel compatibility.
Does correct tire fitment matter for a 1957 Lancia Flaminia restoration?
Correct tire fitment matters a great deal on a 1957 Lancia Flaminia because the car uses a millimetric wheel and tire convention that is visually and mechanically distinct from common inch-based setups. Using the right format helps preserve the proper stance, wheel relationship, and overall presentation.
That matters both for appearance and for avoiding avoidable fitment mistakes during restoration. A car can look finished yet still be mismatched at the wheel and tire level if the millimetric standard is overlooked. Owners concerned with originality should compare the current setup with marque-club guidance or period documentation before choosing sidewall style or replacing wheels.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1957 Lancia Flaminia?
Yes. Modifications can affect tire fitment on a 1957 Lancia Flaminia, especially if the car has aftermarket wheels, altered ride height, brake conversions, or body and suspension changes. Even when the tire size remains in the correct millimetric family, the actual wheel and clearance situation may no longer match a stock-style setup.
That is why the car should be checked as it sits today rather than assumed to follow its original configuration. Wheel diameter, wheel width, and available fender and steering clearance all matter. A Flaminia that has been restored over many years may also carry mixed parts, so a careful inspection before tire replacement is well worth the time.
What should I inspect before driving a 1957 Lancia Flaminia on new tires?
Before driving a 1957 Lancia Flaminia on new tires, inspect the wheels for the correct 400mm size, check that the tires are seated properly, and make sure there is no interference at the fenders, suspension, or steering components. It is also wise to look over valve stems, balance, and overall wheel condition.
Collector cars often need a broader road-readiness check beyond the tires themselves. Sidewall clearance at full lock, air retention after initial inflation, and the condition of suspension and steering parts all deserve attention. A short local test drive followed by a second inspection can reveal rubbing, settling, or pressure changes before any longer outing.
How should 165R400 tires on a collector 1957 Lancia Flaminia be maintained?
165R400 tires on a collector 1957 Lancia Flaminia should be maintained with regular pressure checks, visual inspections for cracking, cuts, bulges, and uneven wear, and periodic checks for air loss after the car has been sitting. Low-use collector vehicles can age their tires out long before they wear them out.
Storage conditions matter almost as much as mileage. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the sidewalls and casing over time. It also helps to inspect the spare and verify the wheel condition whenever the road tires are serviced, since older collector-car equipment is often used infrequently.
