1958 Lancia Tire Fitment Guide

1958 Lancia vehicles use three sizes across the model range: 155R15 for the Appia, plus 165-400 and 165R400 for the Aurelia and Flaminia. The Appia's tire fits a 15-inch wheel, while the Aurelia and Flaminia use 400mm millimetric wheels. For 155R15, available rim width guidance runs from 4.00 to 5.50 inches. For 165R400, available products list rim width ranges of 4.50 to 6.00 inches and 6.0 to 7.0 inches, depending on the tire.

That means year and make alone are not enough for a correct tire choice on a 1958 Lancia. Appia owners need to stay within the 15-inch fitment family, while Aurelia and Flaminia owners need to confirm that their cars still wear the proper 400mm wheels before choosing between the related millimetric sizes. If the car has been modified over the years, checking the actual wheel before ordering is the safest first step.

On a 1958 Lancia, 155R15 identifies a metric radial tire with a nominal section width of 155 millimeters and a 15-inch rim diameter. The R indicates radial construction. Because it is written in the older Euro-metric style without a stated aspect ratio, it generally corresponds to the period 80-series convention used on many European radial tires.

For a 1958 Lancia Appia, that code matters because it separates the car from the larger Lancia models that use millimetric 400mm wheels. It also helps explain why modern-looking metric dimensions appear on a period car: European makers were early users of radial and metric tire standards. When comparing products in this size, pay attention to the full sidewall marking, since some versions differ in speed rating and tube-type versus tubeless construction.

On a 1958 Lancia, 165R400 is a Euro-metric radial size with a nominal section width of 165 millimeters and a 400mm wheel diameter. The R signifies radial construction, and the 400 number is not inches converted into a modern code but the wheel diameter itself in millimeters. Available examples in this size carry an S speed rating, which corresponds to a 112 mph ceiling, and they are tube-type tires.

That code is especially important on a 1958 Lancia Aurelia or Flaminia because 400mm wheels are a distinct fitment family. A 400mm tire cannot be treated as interchangeable with a 15-inch tire simply because the numbers look close at a glance. Owners preserving original European wheel equipment should read the sidewall carefully and confirm the wheel marking before choosing between the millimetric options available for those models.

1958 Lancia tires are available in more than one sidewall style, but the choices depend on size. The 155R15 Appia fitment is offered in blackwall form. The 165R400 fitment used on Aurelia and Flaminia is available in both blackwall and narrow whitewall versions. That gives owners of the larger cars some visual flexibility while keeping the correct millimetric radial sizing.

A blackwall usually suits a restrained European factory look, especially on smaller or more sporting presentations. A narrow whitewall can complement a more formal, luxury-oriented appearance on cars such as the Aurelia and Flaminia without moving into an exaggerated American-style treatment. If show authenticity matters, choose the sidewall style that best matches the market, coachwork, and presentation style of your specific 1958 Lancia rather than selecting only by appearance.

Firestone and Michelin both offer tires for 1958 Lancia applications, but they do not cover the same sizes equally. In 155R15 for the Appia, available options include Firestone and Michelin. In 165R400 for the Aurelia and Flaminia, the available products are Michelin. That brand spread reflects the different character of the fitments, with the millimetric European size remaining closely tied to Michelin's historic radial catalog.

For an Appia, that broader mix gives you more room to compare product character within the same size. For an Aurelia or Flaminia, Michelin's presence in 400mm radial sizing makes it the focal point for preserving the intended wheel-and-tire relationship. Brand choice should come after confirming the actual size on the car, because a correct 400mm fitment matters more than forcing a preference for one brand across the whole 1958 Lancia range.

For 1958 Lancia Aurelia and Flaminia applications in 165R400, Michelin X Radial and Michelin X-Stop differ in sidewall treatment, weight, and listed rim-width range. The Michelin X Radial in this size is a narrow whitewall weighing 17 pounds with a listed rim-width range of 6.0 to 7.0 inches. The Michelin X-Stop is a blackwall weighing 20 pounds with a listed rim-width range of 4.50 to 6.00 inches. Both are radial, tube-type, and carry an 87S marking.

Those differences make the choice less about basic fitment family and more about wheel specification and presentation. Owners should compare the actual wheel width on the car to the tire's listed range, then decide whether a blackwall or narrow whitewall better suits the vehicle's appearance. When a car has non-original wheels or a restoration that blends periods, the rim-width range is the more important checkpoint than the cosmetic distinction.

1958 Lancia rim-width guidance varies by size. For 155R15, listed products show a rim-width range of 4.00 to 5.50 inches. For 165R400, one available tire lists 4.50 to 6.00 inches and another lists 6.0 to 7.0 inches. Those figures are product-specific within the same size family, not a single universal number for every tire offered for a 1958 Lancia.

That matters most when you are working with original European wheels, coachbuilt variants, or a car that has had wheels changed over time. Before selecting a tire, measure or confirm the actual wheel width and compare it to the listed range for the exact product you want. Staying inside the proper rim-width range helps preserve intended section shape, steering response, and overall fit on a collector car that may be driven only occasionally.

Inner-tube requirements on 1958 Lancia tires depend on the exact size and product. The available 165R400 tires for Aurelia and Flaminia are tube-type. In 155R15 for the Appia, tube status varies by product: Michelin X is listed as TL, Michelin XAS is TT, and Michelin XAS-FF is TL. That means the size alone does not answer the tube question on the Appia.

Tube choice should follow the specific tire and the wheel being used, not a broad assumption about all 1958 Lancia tires. Original wheel design, bead condition, and valve-stem setup all matter, especially on older European cars. If you are maintaining original wheels, confirm the sidewall marking on the exact tire you intend to use and match the setup accordingly rather than mixing tube and tubeless practices casually.

A 1958 Lancia should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources that accelerate rubber aging. Keep the tires clean, properly inflated, and off damp ground. Periodically rolling the car helps prevent long static loading in one spot, which is especially helpful on collector vehicles that sit for extended periods between drives.

Good storage habits preserve both appearance and drivability on a low-use classic. Cars such as the Appia, Aurelia, and Flaminia often spend more time parked than driven, so sidewall condition can age out before tread wears down. If the car will remain stationary for a long period, some owners use stands or slightly increase movement frequency to reduce flat-spotting and stress on the carcass while keeping the suspension safely supported.

Tires on a 1958 Lancia usually age out before they wear out, especially on collector cars that see limited annual mileage. A practical rule is to begin evaluating them closely once they reach about five to seven years of age and to treat the ten-year mark as a strong replacement consideration regardless of remaining tread. The DOT date code, visible on modern reproduction tires, is the simplest way to establish age.

That time-based approach is more useful than mileage on a hobby car. A lightly driven Aurelia, Flaminia, or Appia may still look usable while the rubber has hardened, cracked, or lost flexibility. Age, storage conditions, and inflation history matter more than odometer totals. If the car is driven at highway speed or on longer tours, replacing old but unworn tires is often wiser than trying to maximize cosmetic tread life.

Tires on a 1958 Lancia should be inspected before every drive and again before any longer outing or event. Check for sidewall cracking, tread separation, irregular wear, cuts, bulges, and pressure loss. On tube-type applications such as the available 165R400 products, it is also smart to inspect the valve stems and watch for slow leaks that may not show up on a car driven only occasionally.

Frequent inspection is especially important because older collector cars often sit for weeks at a time, and tire issues can develop quietly during storage. A quick look before leaving the garage can catch age-related cracking or a low tire before it becomes a roadside problem. Any change in steering feel, vibration, or how the car tracks should prompt a closer inspection even if the tires still look presentable at first glance.

A 1958 Lancia Appia would have been associated with radial-era European practice, and the available fitment here is 155R15. That aligns with Lancia's reputation for using advanced engineering solutions earlier than many mass-market contemporaries. A modern replacement should still match the original size family and wheel diameter first, with brand and product series chosen afterward according to the restoration's goals.

For show-level accuracy, the final decision should account for market destination, body style, and the standard expected by the event where the car will be judged. Sidewall appearance, construction style, and the exact size convention can all matter on a European classic. If you are chasing factory-correct details, use marque specialists and Lancia club resources to confirm what was delivered on your specific 1958 Appia configuration.

Correct tire fitment matters on a 1958 Lancia because judges and knowledgeable enthusiasts often notice size, construction style, sidewall treatment, and overall stance immediately. A 15-inch Appia tire does not belong on a millimetric-wheel Aurelia or Flaminia, and an incorrect sidewall style can alter the visual character of the car even when the basic dimensions seem close. On period European cars, that visual and technical match is part of the restoration story.

For a local driver-level event, small deviations may matter less than overall condition and presentation. For marque judging or higher-level concours, however, a mismatch in size convention or wheel diameter can stand out quickly. Owners who plan to show their cars should decide early whether the goal is factory-style authenticity, touring practicality, or a balanced compromise, then choose the tire that supports that direction consistently across all four wheels and the spare.

A 1958 Lancia Aurelia and 1958 Lancia Flaminia belong to the millimetric radial fitment family represented here by 165-400 and 165R400. That matches the period European practice seen on larger, higher-end cars that used metric wheel diameters rather than conventional American inch-based sizing. The important original-correct principle is preserving the 400mm wheel relationship and the proper overall visual character rather than substituting a near-looking inch size.

Because many surviving cars have been altered over the decades, owners should confirm whether the original 400mm wheels are still present before selecting a tire. Once that is established, sidewall style becomes part of the authenticity conversation as well, especially on formal grand touring and luxury models. If the car will be judged, consult Lancia-specific resources for body and market nuances, then choose the millimetric radial that best matches the intended restoration standard.

1958 Lancia tires can be suitable for highway use when they are the correct size, in sound condition, and used within their construction and speed-rating limits. The available 165R400 products carry an S rating, which corresponds to 112 mph. The available 155R15 products include T-rated versions at 118 mph and H-rated versions at 130 mph. Those figures are higher than normal U.S. highway speeds, but tire condition and proper fit remain more important than the raw rating alone.

A roadworthy tire is only one part of highway confidence in a late-1950s Lancia. Brake condition, steering wear, suspension health, wheel integrity, and alignment can matter just as much as the tire itself, especially on cars designed in a different traffic era. Before regular highway use, make sure the tires match the wheels correctly, hold pressure consistently, and show no signs of age-related deterioration that could compromise stability or safety.

Inflation pressure on a 1958 Lancia should follow the vehicle maker's recommendations for the specific model and the tire maker's guidance for the exact tire being used. One available 155R15 tire lists a maximum load capacity of 1045 pounds at 44 psi. That figure is the tire's rated maximum for load carrying, not a blanket operating pressure for every 1958 Lancia application or for every tire in the range.

The practical approach is to start with the original vehicle specification for your Appia, Aurelia, or Flaminia, then confirm that it remains appropriate for the reproduction or replacement tire installed. Do not transfer a pressure figure from 155R15 to 165R400, or from one brand and series to another, just because the cars share the same year. Matching pressure to both the vehicle and the exact tire helps preserve handling, ride quality, and tread wear.

Before taking a 1958 Lancia on a longer drive, inspect all five tires if the spare is carried, not just the four on the ground. Look for cracking, cuts, bulges, uneven wear, and anything lodged in the tread, then verify cold pressure and confirm the valve stems are in good condition. On tube-type 165R400 setups, pay extra attention to slow pressure loss and stem condition because those issues may not show themselves on short local outings.

A longer drive also calls for a broader vintage-car check beyond the tires alone. Wheel fastener security, jack and spare readiness, brake feel, fluid levels, and steering response all deserve attention before departure. For cars like the Aurelia and Flaminia that may still wear specialized millimetric wheels, it is especially wise to verify that the spare matches the road tires in both size and wheel type so a roadside change does not create a second problem.
