The 1961 Lancia Flaminia came from an era when Italian grand touring cars blended advanced engineering with formal coachwork and refined road manners. For many owners, its appeal today is not just style, but the way every detail contributes to the character of the car on the road. Tire selection matters because this Flaminia uses millimetric radial sizing, with 175-400 and 175R400 both associated with the model. That puts the focus on choosing the proper radial fitment in the correct format while preserving the car’s balanced period presentation. For restoration-minded use or regular touring, wheel compatibility and overall fitment should be confirmed before any replacement is chosen.
Which Tire Size Is Right for The 1961 Lancia Flaminia
The 1961 Lancia Flaminia is associated with two primary tire sizes, 175-400 and 175R400, and both are radial millimetric fitments rather than familiar inch-based American sizing. Because the covered 2.8 & 3B sub-model uses both sizes, the key decision is understanding the sizing format on the car now and confirming that the wheels match the intended millimetric radial tire before selecting a replacement.
The 175-400 size is a classic millimetric radial format, with 175 identifying nominal section width in millimeters and 400 indicating a 400-millimeter rim diameter. Radial construction suits the 1961 Lancia Flaminia’s touring character and reflects the kind of fitment approach associated with many sophisticated European cars of the period. For buyers, this size calls for attention to correct wheel measurement and tire format rather than assuming interchangeability with inch-based sizes. It is the right choice to evaluate when the car retains its original millimetric wheel setup and a traditional period-style radial presentation is the goal.
The 175R400 size is also a millimetric radial tire, using 175 as the nominal section width in millimeters, R to indicate radial construction, and 400 for rim diameter in millimeters. On a 1961 Lancia Flaminia, this format keeps the decision centered on proper wheel compatibility and authentic-looking radial fitment rather than switching to a modern inch-based size. The practical difference for most buyers is how the size is expressed, so the existing wheel and tire markings should be checked carefully. This size is worth considering when maintaining the Flaminia’s original-style European tire format matters.
Fitment is straightforward here because the covered 2.8 & 3B sub-model is associated with the same millimetric radial tire choices. Checking the exact sub-model still matters so the tire format on the car can be matched to the wheel setup before replacement.

1961 Lancia Flaminia 2.8 & 3B
The 1961 Lancia Flaminia 2.8 & 3B uses 175-400 and 175R400 radial tire sizing, both in millimetric format. Tire selection is less about choosing between different fitment groups and more about confirming the wheel measurement and preserving the correct period-style radial presentation for 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.
Frequently Asked Questions
These FAQs focus on the millimetric radial sizing used on the 1961 Lancia Flaminia, along with wheel fitment, choosing between the two size formats, restoration-minded appearance, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 1961 Lancia Flaminia?
The 1961 Lancia Flaminia is associated with two radial tire sizes: 175-400 and 175R400. Both are classic millimetric fitments rather than common inch-based sizes, and both are used on the covered Flaminia 2.8 & 3B configuration.
That means the next step is not guessing by appearance, but checking what is fitted to the car now and confirming the wheel measurement. A Flaminia with original-style millimetric wheels needs the proper millimetric radial format, so the sidewall markings and wheel setup should be verified before choosing a replacement tire.
Do all 1961 Lancia Flaminia sub-models use the same tire size?
The covered 1961 Lancia Flaminia 2.8 & 3B sub-model is associated with the same pair of radial tire sizes, 175-400 and 175R400. There is no separate primary size split within that covered sub-model group.
Even with shared fitment, it still helps to confirm the exact tire marking already on the car. Millimetric European sizing can be unfamiliar today, and the best replacement choice depends on matching the wheel format and preserving the proper overall fitment approach rather than assuming any modern-looking radial of similar width will work.
What does 175R400 mean on a 1961 Lancia Flaminia?
On a 1961 Lancia Flaminia, 175R400 identifies a radial tire with a nominal section width of 175 millimeters and a 400-millimeter rim diameter. The R in the size code indicates radial construction, which sets it apart from older bias-ply sizing conventions.
The important practical point is that 400 refers to a millimetric wheel size, not a 15-inch or 16-inch rim. Before ordering replacement tires, the wheel and the old tire markings should be checked closely so the new tire matches the car’s actual millimetric setup and does not create an avoidable fitment problem.
Choosing the Right Tire
What should I consider when choosing a 175-400 tire for a 1961 Lancia Flaminia?
Start with the exact size already fitted to the car and confirm that the wheel is meant for a 400-millimeter radial tire. On a 1961 Lancia Flaminia, 175-400 is part of a millimetric radial fitment, so staying with the correct format is more important than trying to substitute a visually similar inch-based tire.
After size and wheel compatibility are confirmed, the decision shifts to how the car will be used. A restoration-oriented Flaminia may call for a more traditional presentation, while a regularly driven car still needs careful attention to tire age, condition, and clearance so the replacement supports the car’s intended road use.
How do I choose between the available 175-400 and 175R400 tires for a 1961 Lancia Flaminia?
The main difference is the way the size is expressed, not a change from radial to bias-ply construction. Both 175-400 and 175R400 are radial millimetric fitments associated with the 1961 Lancia Flaminia, so the correct choice depends on matching the wheel and tire format already used on the car.
Checking the existing sidewall marking is the safest starting point, followed by confirming the wheel measurement itself. That keeps the focus on proper compatibility and avoids treating two similar-looking designations as automatically interchangeable without verifying how the car is actually equipped.
What rim-fitment details matter when choosing tires for a 1961 Lancia Flaminia?
Rim format matters as much as tire size on the 1961 Lancia Flaminia because the car uses millimetric radial sizing. A 175-400 or 175R400 tire is intended for a 400-millimeter wheel, so confirming the wheel’s actual measurement is essential before selecting a replacement.
That check becomes especially important if the car has had wheels changed at some point in its life. Measure the wheel carefully, compare it to the markings on the current tire, and make sure the replacement tire matches the wheel format, vehicle clearance, and intended use rather than relying on guesswork.
Restoration & Appearance
Which tire should I choose for a period-style 1961 Lancia Flaminia?
A period-style approach starts with the proper millimetric radial size used on the 1961 Lancia Flaminia, either 175-400 or 175R400 depending on the wheel and tire format already on the car. That preserves the Flaminia’s European touring character far better than replacing it with a generic modern inch-based tire.
For a restoration-minded car, appearance and sizing convention both matter. Matching the tire format to the original-style wheel setup helps maintain the car’s visual balance, and owners pursuing exact historical accuracy should also compare their choice against marque references, surviving examples, or restoration records specific to their car.
Does correct tire fitment matter for a 1961 Lancia Flaminia restoration?
Yes, correct tire fitment matters on a 1961 Lancia Flaminia restoration because the car’s millimetric radial sizing is part of its period engineering character. Using the proper 175-400 or 175R400 format helps preserve the stance and visual proportion that suit the car.
Fitment also affects how convincing the finished restoration feels in use. Even if the goal is mainly appearance, the wheel format, mounted size, and clearance still need to work together, so the best restoration result comes from treating tire selection as both an aesthetic decision and a mechanical one.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1961 Lancia Flaminia?
Yes, modifications can affect tire fitment on a 1961 Lancia Flaminia, especially if the car has different wheels, altered suspension height, or body changes. Because the original-style fitment uses millimetric radial sizing, any move away from that wheel format can change what tire sizes can reasonably be used.
A Flaminia with later wheels should have both wheel measurement and available clearance checked before replacement tires are chosen. Steering clearance, fender space, and suspension condition all matter, and those checks are more useful than assuming the tire that came on the car recently is automatically the right fit.
What should I inspect before driving a 1961 Lancia Flaminia on new tires?
Before driving a 1961 Lancia Flaminia on new tires, inspect the wheels, valve stems, and overall tire mounting condition, then confirm inflation pressure, clearance, and even seating on the rim. It also helps to look over steering and suspension components so the new tires are not being asked to compensate for worn hardware.
A short initial drive should be followed by another visual check for rubbing, uneven stance, or any sign of air loss. On a collector car, that early inspection is especially worthwhile because long storage, infrequent use, and aging chassis components can reveal problems only after the tires are back in service.
How should tires on a collector 1961 Lancia Flaminia be maintained?
Tires on a collector 1961 Lancia Flaminia should be checked regularly for pressure, tread condition, sidewall cracking, bulges, cuts, and any sign of slow air loss. Even when mileage is low, age and storage conditions can affect radial tires long before tread wear becomes the deciding factor.
Proper storage also helps preserve a seldom-driven Flaminia. Keeping the car away from prolonged sunlight, moisture, heat, and ozone sources can reduce premature tire aging, and periodic inspections remain important because collector vehicles often spend enough time parked that condition, rather than mileage, becomes the real maintenance concern.
