The 1965 Lancia Flaminia sits in the refined end of the Italian grand touring world, a car remembered for its engineering sophistication and elegant coachbuilt presence as much as its road manners. Owners approaching tire selection for a Flaminia are usually balancing authenticity of appearance with confidence in real road use. For this model, the key fitment question centers on two radial millimetric sizes, 175-400 and 175R400, both tied to the car’s original-era European tire vocabulary. That means the decision is less about choosing between bias-ply and radial construction, and more about confirming the exact sizing convention, preserving the Flaminia’s character, and checking wheel compatibility before installation.
Which Tire Size Is Right for The 1965 Lancia Flaminia
The 1965 Lancia Flaminia uses two primary tire sizes, 175-400 and 175R400, and both are radial millimetric fitments. Because these sizes share the same basic sizing family and appear on the Flaminia 2.8 & 3B, the first step is confirming which marking matches the car’s current wheel and existing tire setup. Once that is settled, the real decision becomes selecting the right tire presentation and verifying compatibility with the vehicle as it sits today.
The 175-400 designation is a classic millimetric radial size, using a 175 millimeter nominal width and a 400 millimeter wheel measurement rather than the inch-based rim diameters more familiar on American applications. Its radial construction suits the Flaminia’s European touring character and keeps the tire selection aligned with the car’s original-era sizing language. Buyers considering this size should pay close attention to the wheel itself, since millimetric fitments require the correct wheel specification. It is the right choice when the car is equipped for 175-400 fitment and the goal is to stay within that established sizing system.
The 175R400 size is also a millimetric radial, with 175 indicating nominal section width in millimeters, R identifying radial construction, and 400 referring to the wheel measurement in millimeters. On a 1965 Lancia Flaminia, this size continues the period European approach to tire fitment rather than converting the car to a later inch-based format. The practical difference for the buyer is careful verification of the wheel and existing tire markings before selection. This size makes sense for a Flaminia already set up for 175R400 fitment and for owners preserving a traditional roadgoing presentation.
Tire fitment for the covered 1965 Lancia Flaminia sub-model is straightforward, with the same pair of radial millimetric sizes appearing within the range. Checking the exact sub-model still matters, because vintage European wheel and tire markings should be confirmed before choosing between closely related size designations.

Frequently Asked Questions
These FAQs focus on the 1965 Lancia Flaminia’s millimetric radial tire sizes, how to interpret 175-400 and 175R400, what to verify at the wheel, and what collectors should inspect before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 1965 Lancia Flaminia?
The 1965 Lancia Flaminia uses two primary radial tire sizes: 175-400 and 175R400. Both are classic European millimetric fitments rather than modern inch-rim sizes, and both are associated with the Flaminia 2.8 & 3B. That makes the main fitment question less about broad size range and more about identifying which of these two markings matches the car’s actual wheel and tire setup.
A Flaminia owner should inspect the wheel and the tires already on the car before choosing between them. Millimetric sizing can look deceptively close to other vintage formats, so matching the exact system matters. If the car has been changed over the years, verify wheel dimensions, clearance, and overall setup before installing new tires.
Does the 1965 Lancia Flaminia 2.8 & 3B use the same tire size?
The 1965 Lancia Flaminia 2.8 & 3B is associated with the same two radial millimetric sizes used on this model range: 175-400 and 175R400. That means sub-model selection does not introduce a separate bias-ply fitment or a different sizing family. The choice still comes down to matching the exact tire marking and wheel specification already present on the car.
That consistency helps narrow the search, but it does not remove the need to inspect the actual wheels. Vintage European cars are often restored, stored, or modified over time, and a Flaminia may no longer wear its earlier configuration. Confirm the current wheel type and tire designation before ordering so the replacement matches the car’s real-world setup.
What does 175R400 mean on a 1965 Lancia Flaminia?
On a 1965 Lancia Flaminia, 175R400 is a radial millimetric tire size. The 175 refers to nominal section width in millimeters, the R indicates radial construction, and 400 refers to the wheel measurement in millimeters. It belongs to the traditional European sizing language used on cars of this period rather than the inch-based rim diameters common on many later vehicles.
The practical takeaway is that a 400 millimeter wheel is not the same thing as a 15-inch or 16-inch wheel, even if the dimensions seem close at a glance. Before replacing old tires, check the wheel markings and compare them to the tire designation already fitted. That extra step helps avoid ordering the right-looking size in the wrong format.
Choosing the Right Tire
What should I consider when choosing a 175-400 tire for a 1965 Lancia Flaminia?
Start with the basics: the 175-400 size itself, radial construction, and the fact that it is a millimetric vintage European fitment. On a 1965 Lancia Flaminia, the right choice depends on matching the wheel specification already on the car and keeping the tire size consistent with the vehicle’s existing setup. For many owners, appearance and period character matter nearly as much as the fitment number.
A good selection process includes checking the current tire markings, inspecting wheel condition, and deciding whether the goal is restoration-oriented presentation or regular touring use. Cars that have sat for long periods deserve extra scrutiny for wheel corrosion, old repairs, and clearance issues. Choosing carefully helps preserve the Flaminia’s stance and avoids introducing an incompatible wheel-and-tire combination.
What should I consider when choosing a 175R400 tire for a 1965 Lancia Flaminia?
The key consideration with 175R400 is confirming that the Flaminia is actually set up for that exact radial millimetric designation. The size represents a traditional European radial format, so selection should center on wheel compatibility, proper sizing continuity, and the kind of use the car will see. A careful buyer also thinks about how the tire’s appearance supports the car’s overall restoration direction.
It helps to inspect the old tires and wheels together rather than treating the sidewall marking in isolation. Collector cars may carry older replacements, changed wheels, or long-stored components that no longer reflect the intended setup. Checking the wheel specification, overall condition, and available clearance before mounting tires is the best way to avoid preventable fitment problems.
How do I choose between the available 1965 Lancia Flaminia tires?
Choosing between 175-400 and 175R400 begins with identifying which marking belongs on the actual wheel fitted to the car. Since both are radial millimetric sizes associated with the 1965 Lancia Flaminia, the decision is not a simple modern upsizing question. It is a matter of matching the vintage European sizing system already present and keeping the fitment consistent with the car’s intended character.
The most useful next step is a hands-on inspection of the wheel and the tire currently mounted. A restored or long-owned Flaminia may have changes that are not obvious from the outside. Once the exact size system is confirmed, the buyer can focus on condition, appearance goals, and safe compatibility instead of guessing between two similar-looking designations.
Restoration & Appearance
Which tire should I choose for a period-style 1965 Lancia Flaminia?
A period-style 1965 Lancia Flaminia should stay within its correct millimetric radial sizing family, using either 175-400 or 175R400 as appropriate for the wheel and current setup. That approach preserves the car’s European tire character far better than moving casually into a modern inch-based size. For restoration-minded owners, the visual proportion and proper vintage sizing language are part of the appeal.
The most accurate choice depends on the wheels actually installed and on how exact the restoration needs to be. When originality is especially important, compare the car against marque references, restoration photographs, or historical documentation tied to the specific vehicle. That keeps appearance decisions grounded in evidence rather than assumptions based only on a close-looking tire size.
Does correct tire fitment matter for a 1965 Lancia Flaminia restoration?
Correct tire fitment matters a great deal on a 1965 Lancia Flaminia because the tire is a visible part of the car’s stance, wheel presentation, and overall period impression. Using the proper millimetric radial sizing family helps the car look coherent and keeps the restoration aligned with the way European grand touring cars of the era were equipped and presented.
Fitment accuracy also matters mechanically, especially on a car that may have seen decades of repairs or parts changes. A restoration should include checking wheel condition, tire clearance, and the exact sizing marked on the wheel and old tire. That combination of visual accuracy and careful verification usually produces the most satisfying result on the road and on display.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1965 Lancia Flaminia?
Yes, modifications can affect tire fitment on a 1965 Lancia Flaminia, especially if the car has aftermarket wheels, brake changes, suspension alterations, or bodywork that changes clearance. Even when the intended tire size remains 175-400 or 175R400, a changed wheel or altered ride height can shift how the tire sits in the wheel opening and how it behaves at full steering lock.
That is why any Flaminia with an unknown history deserves a careful inspection before new tires go on. Check wheel dimensions, inner and outer clearance, and the condition of suspension components. Vintage cars often accumulate subtle changes over time, and those details matter far more than assuming that every surviving example still matches its earlier configuration.
What should I inspect before driving a 1965 Lancia Flaminia on new tires?
Before driving a 1965 Lancia Flaminia on new tires, inspect the wheels for damage, corrosion, and old repairs, then confirm that the tire size matches the wheel’s millimetric specification. It is also wise to check valve stems, wheel mounting surfaces, and basic suspension condition. A new tire can only perform properly if the supporting components are sound.
Once the tires are installed, look for even seating, proper clearance, and any sign of rubbing while turning or compressing the suspension. Collector cars that have been parked for extended periods should also be checked for cracked rubber bushings, loose steering components, and fluid leaks. A short, cautious test drive is the right way to confirm everything settles in correctly.
How should tires on a collector 1965 Lancia Flaminia be maintained?
Tires on a collector 1965 Lancia Flaminia should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when tread wear is low, age, long periods of inactivity, and environmental exposure can all affect a vintage car’s tires. Sidewall cracking, bulges, cuts, and slow air loss deserve attention long before the car is taken on a meaningful road drive.
Storage conditions matter just as much as mileage on a lightly used grand touring car. Keep the Flaminia away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or compressors. It also helps to move the car periodically or support it properly during longer storage so the tires are not left carrying load in one position for months.
