1964 Lancia Tire Fitment Guide

1964 Lancia vehicles use four distinct tire sizes, and each model has its own fitment. The Flaminia uses 175-400 and 175R400, both on 400 mm rims. The Flavia uses 165R15 on a 15-inch rim, while the Fulvia uses either 155R14 radial or 520-14 bias-ply on a 14-inch rim. Where rim width guidance is available, 165R15 fits 4.50 to 6.00 inch rims, 155R14 fits 4.00 to 5.50 inch rims, and 520-14 fits 3.50 to 4.00 inch rims.

The practical takeaway is that year and make are only the starting point for 1964 Lancia fitment. You need to identify the exact model first, then confirm the wheel diameter already on the car. That matters especially with the Flaminia, because 400 mm wheels are not interchangeable with 15-inch or 14-inch fitments, and with the Fulvia, where the correct choice may depend on whether you want to keep a bias-ply presentation or move to a radial setup.

On a 1964 Lancia, 165R15 is a Euro-metric radial size. The 165 refers to a nominal section width of 165 millimeters, the R identifies radial construction, and the 15 is the wheel diameter in inches. On this year and make, that size applies to the Flavia and is offered in blackwall, narrow whitewall, and wide whitewall versions from several brands.

That decoding helps you avoid mixing format families that may look similar on paper but do not fit the same wheel. A Flavia owner choosing 165R15 can focus on sidewall appearance and brand preference, while someone with a Flaminia or Fulvia needs to start elsewhere. If your car already has older tires mounted, matching the sidewall size exactly before ordering is the safest way to stay on the correct diameter and general profile.

No, 1964 Lancia models do not use the same tire size. The Flaminia uses 400 mm radial sizing, the Flavia uses 165R15, and the Fulvia uses either 155R14 radial or 520-14 bias-ply. That spread reflects how different these cars were in size, market position, and wheel specification even within one model year.

For a buyer, that means the model name is just as important as the year and make. A Flaminia owner needs to verify the 400 mm wheel fitment first, a Flavia owner can concentrate on 15-inch radial choices and sidewall look, and a Fulvia owner may need to decide between keeping a more original bias-ply appearance or using a radial configuration for regular driving. Checking the existing tire markings and wheel diameter before moving forward prevents the most common ordering mistake.

For a 1964 Lancia Fulvia, the 155R14 and 520-14 represent two different construction approaches on the same 14-inch wheel diameter. The 155R14 is a radial size available in blackwall form from Michelin and Firestone, while the 520-14 is a bias-ply size from Premium Sport with narrow whitewall styling. The choice is less about whether the tire belongs to the Fulvia and more about how you want the car to look and feel on the road.

Owners focused on a period-oriented presentation often prefer the bias-ply 520-14 because it better matches the look associated with small European cars of the era. Owners who expect more routine road use often lean toward the 155R14 radial because radial construction generally delivers more familiar straight-line and cornering behavior to modern drivers. The best first step is to confirm the wheel itself, then decide whether authenticity or more contemporary drivability matters more for how your Fulvia will be used.

1964 Lancia tire sidewall choices vary by size and model. The Flavia’s 165R15 has the broadest appearance range, with blackwall, narrow whitewall, and wide whitewall options. The Fulvia’s 155R14 radial choices are blackwall, while the 520-14 bias-ply options use narrow whitewall styling. That means sidewall appearance is a real selection factor on some 1964 Lancia applications, not just a minor cosmetic detail.

For most Italian cars of this period, blackwall is usually the safest direction if your goal is a restrained European look, especially on the smaller and more sporting end of the range. Whitewall options can still appeal depending on personal taste, market presentation, or a custom restoration theme, but they create a distinctly different visual character. If show authenticity matters to you, compare your intended sidewall treatment with period photos and the standards used by the club or event where the car will be judged.

Several brands cover 1964 Lancia fitments, depending on the model and size. The Flavia’s 165R15 is available from Coker Classic, American Classic, Firestone, and BFGoodrich. The Fulvia’s 155R14 is available from Michelin and Firestone, while the 520-14 bias-ply option comes from Premium Sport. Brand choice is therefore tied closely to the size your model uses rather than to 1964 Lancia as a whole.

That matters because brand selection often overlaps with sidewall appearance and the style of restoration you are pursuing. A Flavia owner has the widest mix of visual options within one size, while a Fulvia owner choosing 520-14 is also choosing a more specialized bias-ply presentation. Start by confirming the exact size on your car, then narrow by sidewall look, construction, and any speed or load markings that matter for the way you drive your Lancia.

Rim width requirements for 1964 Lancia tires depend on the size. The 165R15 used on the Flavia fits rims from 4.50 to 6.00 inches wide. The 155R14 used on the Fulvia fits rims from 4.00 to 5.50 inches wide, and the 520-14 bias-ply Fulvia size fits rims from 3.50 to 4.00 inches wide. Those ranges show that even two sizes sharing the same wheel diameter can call for different wheel widths.

That is why checking the actual wheel before ordering matters as much as checking the sidewall size. A Fulvia owner moving between 520-14 and 155R14 should confirm wheel width instead of assuming every 14-inch wheel is equally suitable for both. If the wheel width is not immediately obvious, measuring it or having it verified by a knowledgeable shop or marque specialist is a smart step before finalizing a tire choice.

Inner-tube requirements for 1964 Lancia tires vary by size and sometimes by product. One 155R14 radial option for the Fulvia is marked TL, which means tubeless, while the other 155R14 option does not carry that same marking. The 165R15 Flavia options are not marked with tube information in the size itself here, and the 520-14 bias-ply Fulvia options should be checked carefully against the wheel type and the exact tire selected.

The safest approach is to match the tire choice to the wheel design already on the car and verify the sidewall markings on the exact product before mounting. Older collector cars often retain original-style wheels, and tube use can depend on the wheel as much as the tire. If your Lancia still has original wheels, especially on a less common fitment, confirming tube compatibility before installation is more important than relying on assumptions drawn from size alone.

Original 1964 Lancia wheels can only be used with the tire sizes that match their diameter and suitable width range. A Flaminia wheel for 175-400 or 175R400 is a 400 mm wheel and is not the same as a 15-inch or 14-inch wheel. The Flavia’s 165R15 belongs on 15-inch wheels, and the Fulvia’s 155R14 and 520-14 both use 14-inch wheels, though their rim width needs are not identical.

That means interchangeability is limited even within one make and year. The clearest example is the Flaminia, where the metric wheel diameter must be respected exactly. On the Fulvia, the shared 14-inch diameter makes comparison easier, but wheel width still needs to be checked before moving between the radial and bias-ply options. If your car has had wheels changed at some point in its life, verify the wheel dimensions directly rather than assuming the current setup is original.

A 1964 Lancia should be stored in a cool, dry, dark environment with the tires kept away from direct sunlight, electric motors, battery chargers, and other ozone-producing equipment. Clean concrete is better than damp ground, and maintaining proper inflation helps the carcass hold its shape. On a car like the Fulvia, a bias-ply 520-14 is generally more prone to temporary flat-spotting during long periods of sitting than a radial 155R14.

If the car will sit for extended periods, rolling it periodically or supporting it in a way that reduces constant load on one contact patch can help preserve the tires. Storage habits matter even more on collector cars that are driven infrequently, because age and environment usually matter more than mileage. A simple routine of covering the car, controlling moisture, and checking pressures every few weeks can do more for tire life than occasional short drives around the block.

Tires on a 1964 Lancia are usually judged by age and condition more than by accumulated miles. A good working rule is to begin evaluating them carefully once they are in the five-to-seven-year range and to treat around ten years as a point where replacement deserves serious consideration, even if tread depth still looks acceptable. The DOT date code on the sidewall is the quickest way to establish age on a modern reproduction tire.

Collector cars often fool owners because the tires can look nearly new after light seasonal use while the rubber itself has hardened with time. That matters on any 1964 Lancia, whether it wears a radial Flavia or Fulvia setup or a bias-ply Fulvia fitment. Sidewall cracking, vibration, repeated air loss, or visible deformation are all signs that age may have become more important than remaining tread, and those symptoms should outweigh mileage when deciding what to replace.

Tires on a 1964 Lancia should be inspected before every drive and again before any longer outing. Look for cracking in the sidewalls, cuts, bulges, uneven wear, embedded debris, and any loss of air pressure since the last drive. On sizes where tube use may apply, valve stems and any signs of tube-related leakage deserve attention as well, because a slowly aging collector tire can fail by air loss long before tread wear becomes obvious.

A brief visual check only takes a minute, but it can prevent the most common trouble vintage cars face on the road. Cars that spend long stretches parked can develop age-related issues without much warning, and lower annual mileage does not reduce that risk. Make tire inspection part of the same routine as checking fluids, lights, and brakes, especially before club tours or events where your 1964 Lancia may cover more miles in a day than it does in a typical month.

A 1964 Lancia Flaminia used 400 mm radial sizing, represented here by 175-400 and 175R400. That is consistent with the Flaminia’s position as a sophisticated Italian flagship from an era when European manufacturers were already embracing radial technology more readily than many American makers. The important original-fitment idea is the combination of radial construction and 400 mm wheel diameter rather than a broad interchange with inch-based wheel sizes.

For restoration work, preserving that 400 mm radial identity matters more than chasing a casual substitute that merely seems close in diameter. It affects both the visual stance of the car and the integrity of the wheel-and-tire package. If your goal is a highly accurate restoration, verify the current wheel markings and compare them with factory literature or a Lancia marque specialist, especially because wheel changes over the decades can blur what a particular Flaminia wears today.

Correct tire fitment matters on a 1964 Lancia because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style immediately. A Flaminia shown with the wrong wheel-diameter family would stand out, and a Fulvia entered in a strict originality setting could also draw scrutiny if it wears a radial when a bias-ply presentation better matches the restoration goal. Sidewall treatment matters too, especially when whitewall choices exist but may not suit the intended market look.

That does not mean every event applies the same standard, but it does mean tires should be chosen as part of the restoration, not as an afterthought. The more serious the judging, the more important it becomes to match the car’s intended historical character. Before a concours or marque-specific show, compare your tire construction and sidewall style with period photos and ask the hosting club what it considers acceptable, since event rules can be more precise than general collector-car advice.

The 1964 Lancia Fulvia is associated here with two 14-inch fitments: 155R14 radial and 520-14 bias-ply. That reflects an interesting overlap period in European tire practice, where radial technology was established but traditional bias-ply sizing still remained relevant in certain applications and restoration contexts. The key point is that both the wheel diameter and the construction type matter when trying to represent an early Fulvia faithfully.

For an owner restoring a Fulvia, originality decisions should begin with the car’s existing wheels, period references, and the standard expected by the audience for the finished car. A bias-ply 520-14 will usually communicate a more overtly period look, while a 155R14 radial keeps the car within a historically plausible European metric format. If the car has passed through several owners, consulting period manuals or Lancia club resources is the best way to confirm which direction fits your exact example.

1964 Lancia tires can be suitable for highway driving when they are the correct size, in sound condition, and used within their design limits. The clearest speed-marked example here is the Michelin 155R14 80T TL, where T corresponds to a 118 mph ceiling. Other sizes here do not all carry speed letters in the same way, so safe road use depends just as much on tire age, inflation, and the mechanical condition of the car as on the nominal speed capability of the tire itself.

In real-world collector driving, the limiting factor is often the vehicle rather than the tire, especially on a 1964 car with period brakes, suspension design, and decades-old components elsewhere in the chassis. A well-prepared Flavia, Fulvia, or Flaminia can be very comfortable on modern roads, but long-distance or sustained-speed driving should always be approached with a whole-car mindset. Fresh tires are only one part of that picture, alongside alignment, wheel condition, steering, and brake health.

Inflation pressure on a 1964 Lancia depends on the exact tire size and the specific tire you choose. Load-and-pressure markings here include 165R15 options around 1168 to 1170 pounds at 35 to 36 psi, one 155R14 option at 990 pounds at 44 psi, and 520-14 bias-ply examples at 1230 pounds at 60 psi. Those figures are part of the tire’s rated capability and should not be mistaken for a universal operating pressure across every 1964 Lancia model or every size.

The best approach is to use the factory literature as your starting point for vehicle setup and then compare it with the guidance supplied for the exact tire on the car. Never transfer a pressure number from the Flavia’s 165R15 to the Fulvia’s 520-14, or from a bias-ply tire to a radial, simply because the cars share a year and make. If you are changing construction type, revisit inflation, handling expectations, and wear patterns after the car is back on the road.

Before a longer drive in a 1964 Lancia, inspect each tire for cracking, bulges, cuts, punctures, unusual wear, and proper cold inflation. Check the spare as well, because vintage spares are often older than the road tires and may have been ignored for years. If your setup uses or may use tubes, pay close attention to valve stems and any signs of slow leakage, and make sure wheel condition is part of the inspection rather than focusing on the tread alone.

Tires are only one part of preparing a 1964 car for distance, but they are the easiest part to inspect thoroughly before departure. A sound set of properly sized tires reduces stress on the road and gives you a clearer read on how the car itself is behaving. Pair the tire check with a broader review of brakes, steering, fluids, and charging system condition so your Flaminia, Flavia, or Fulvia is ready for the trip as a complete machine.
