The 1950 Lancia Aurelia arrived at the dawn of a sophisticated new era for Italian touring cars, blending advanced engineering with the poised road manners that made early Aurelias so respected among enthusiasts today. For owners restoring or maintaining one of these cars, tire choice matters not just for appearance, but for preserving the way the chassis feels on the road. The 1950 Lancia Aurelia uses 165-400 and 165R400 millimetric radial sizing, both tied to the distinctive 400mm wheel format. Available choices include Michelin radial designs in blackwall and narrow whitewall form, making it possible to balance period-style presentation with practical road use and careful wheel compatibility.
Which Tire Size Is Right for The 1950 Lancia Aurelia
The 1950 Lancia Aurelia uses two closely related primary tire sizes, 165-400 and 165R400, both in radial millimetric format on 400mm wheels. Because the covered sub-model uses the same fitment family, the key step is confirming the actual wheel setup on the car and then choosing the tire style, rim-width compatibility, and presentation that best suits the restoration or driving goal.
165-400 is a classic millimetric radial size in which 165 identifies the nominal section width in millimeters and 400 refers to the wheel diameter in millimeters rather than inches. Its radial construction suits the 1950 Lancia Aurelia's distinctive European wheel format and reflects the car's advanced period character. This size points the buyer toward traditional millimetric fitment rather than a modern inch-based substitute. It is the right size family to evaluate when keeping the car on its correct 400mm wheel standard and confirming wheel condition before road use.
165R400 is a millimetric radial size that uses 165 as the nominal section width, R to indicate radial construction, and 400 as the wheel diameter in millimeters. On the 1950 Lancia Aurelia, this size connects directly to available Michelin choices, including blackwall and narrow whitewall versions within the Michelin X Radial family. That gives the buyer a meaningful appearance choice while staying in the proper millimetric format. It is the practical size to review when comparing rim-width suitability, sidewall presentation, and overall restoration intent.
Fitment is straightforward for the covered 1950 Lancia Aurelia sub-model, with the same millimetric tire-size family used throughout. Checking the exact sub-model still helps confirm that the car remains on its proper 400mm wheel setup before choosing between available tire styles.

Tire Size & Fitment
What tire size fits a 1950 Lancia Aurelia?
The 1950 Lancia Aurelia uses 165-400 and 165R400 tire sizes. Both are radial millimetric fitments built around a 400mm wheel, which is an important distinction from more familiar inch-based vintage tire sizes. On this car, the main fitment question is not choosing between modern inch sizes, but staying within the proper millimetric format.
That means the first thing to confirm is the actual wheel on the car, especially if it has been restored or modified at some point. A 400mm wheel requires the correct millimetric tire, so verifying wheel markings, condition, and overall compatibility is more important than assuming an inch-designated tire will serve as a substitute.
What size rim does a 1950 Lancia Aurelia use?
The 1950 Lancia Aurelia uses a 400mm rim diameter with its 165-400 and 165R400 tire sizes. This is a millimetric wheel standard rather than a conventional inch-based rim diameter, so the tire and wheel must match in the same measurement system. That detail is central to proper fitment on an early Aurelia.
A buyer should confirm that the car still has its 400mm wheels before selecting tires, since a visually similar inch-based wheel is not the same thing. It also helps to check wheel width, bead-seat condition, and whether the car has had any wheel changes during restoration, because those details affect which available 165R400 product is the better match.
Do all 1950 Lancia Aurelia sub-models use the same tire size?
The covered 1950 Lancia Aurelia sub-model uses the same millimetric tire-size family across the page, with 165-400 and 165R400 identified for Alle Typen. That makes fitment fairly straightforward compared with vehicles that split tire sizes by trim, body style, or wheel package. The main challenge is interpreting the millimetric sizing correctly.
Even with shared fitment, it is still smart to inspect the actual wheels and tires on the car before replacement. Collector vehicles often pass through multiple owners, and wheel swaps or older replacement tires can complicate what appears to be a simple fitment. Confirming the 400mm wheel standard keeps the selection process accurate and avoids ordering by assumption.
Choosing the Right Tire
What should I consider when choosing a 165R400 tire for a 1950 Lancia Aurelia?
Start with the correct millimetric size and the correct 400mm wheel, then compare the available 165R400 radial choices by sidewall style, tire series, and rim-width compatibility. For the 1950 Lancia Aurelia, the available Michelin options keep the selection focused and practical rather than overwhelming. The real decision is how closely the tire should match the car's intended appearance and wheel setup.
A narrow whitewall can shift the visual character of the car, while a blackwall keeps the presentation more understated. It also helps to compare the wheel width on the car to the tire's usable rim-width range, especially on a restored vehicle. That approach keeps the choice grounded in both appearance and fitment instead of style alone.
What sidewall styles are available for 1950 Lancia Aurelia tires?
For the 1950 Lancia Aurelia, available 165R400 tires include both blackwall and narrow whitewall sidewall treatments. Those choices matter because an early European touring car can look noticeably different depending on the sidewall presentation, even when the tire size and construction stay the same. The sidewall choice is one of the clearest visual decisions on this fitment.
A blackwall usually suits a restrained, technical appearance, while a narrow whitewall adds a more formal period-style look. Neither choice changes the need to stay with the proper millimetric radial size and 400mm wheel standard. Sidewall style should be chosen after size and wheel compatibility are confirmed, not as a substitute for careful fitment checking.
What brands offer tires for the 1950 Lancia Aurelia?
Michelin is the brand represented in available 165R400 tires for the 1950 Lancia Aurelia. The product selection centers on Michelin's millimetric radial offerings, including versions within the Michelin X Radial family, which suits the car's distinctive European sizing format. That keeps the brand decision simple and shifts attention to the specific tire configuration instead.
Because the available selection is focused on one marque, the more useful comparison is between sidewall style, rim-width range, and the overall presentation you want from the car. A buyer should also consider whether the Aurelia is being prepared primarily for display, light touring, or general collector driving, since that can shape which version makes the most sense.
Restoration & Appearance
Which tire should I choose for a period-style 1950 Lancia Aurelia?
A period-style 1950 Lancia Aurelia tire choice starts with staying in the proper millimetric radial size family, using 165-400 or 165R400 on the correct 400mm wheels. From there, the available 165R400 Michelin options let the car retain a traditional presentation without stepping outside its distinctive wheel format. The tire's visual effect comes mainly from sidewall style rather than a change in basic fitment.
For a more restrained European look, a blackwall may feel more appropriate, while a narrow whitewall creates a more formal restoration-oriented appearance. If exact historical presentation matters, it is wise to compare the car against period photos, marque-club resources, and restoration documentation. That helps separate a broadly period-style look from a model-specific originality claim.
Does correct tire fitment matter for a 1950 Lancia Aurelia restoration?
Correct tire fitment matters a great deal on a 1950 Lancia Aurelia because the car uses a millimetric 400mm wheel standard rather than a common inch-based setup. Choosing the proper size family preserves the visual proportions of the car and avoids turning the restoration into a compromise at one of its most noticeable contact points. On an Aurelia, the wheel-and-tire relationship is part of the car's character.
Restoration-minded buyers should think beyond tread and sidewall style alone and verify wheel diameter, wheel width, and overall compatibility before mounting new tires. A car that has been stored for years or changed hands several times may no longer have the expected wheel setup. Sorting that out early makes later appearance and product decisions much more straightforward.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1950 Lancia Aurelia?
Yes, modifications can affect tire fitment on a 1950 Lancia Aurelia, especially if the car has had wheel changes, suspension work, or body alterations during restoration. The Aurelia's millimetric 400mm wheel format already makes fitment more specialized, so even modest changes can complicate what tire belongs on the car. A visually similar wheel is not enough to confirm compatibility.
Any Aurelia with non-original wheels should have its actual rim diameter and width checked before a tire is chosen. Suspension height changes, steering-stop adjustments, or fender repairs can also influence clearance once the car is back on the road. Looking at the entire wheel-and-tire package prevents fitment mistakes that might not be obvious when the car is standing still.
What should I inspect before driving a 1950 Lancia Aurelia on new tires?
Before driving a 1950 Lancia Aurelia on new tires, inspect the wheels for damage, confirm the 400mm rim standard, and make sure the tire size matches the wheel exactly. It is also smart to check valve stems, tube requirements where applicable, and whether the tires seat correctly on clean, sound rims. A collector car benefits from a full visual inspection before its first outing.
After installation, verify inflation, look for any rubbing at full steering lock, and watch for signs of air loss after the car has sat overnight. An Aurelia that has been stored for long periods should also have its brakes, suspension, and steering reviewed before regular use. New tires work best when the rest of the running gear is equally ready for the road.
How should 165R400 tires on a collector 1950 Lancia Aurelia be maintained?
165R400 tires on a collector 1950 Lancia Aurelia should be maintained with regular pressure checks, routine visual inspections, and careful storage habits. Because many collector cars see limited annual mileage, tire condition often matters more than tread wear alone. Sidewall cracking, bulges, cuts, flat spotting, and slow air loss deserve attention even when the car appears to be driven only occasionally.
Storage conditions make a real difference on an older touring car. Keeping the Aurelia away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition between drives. It also pays to move the car periodically or adjust storage support to reduce long-term flat spotting. A short inspection before each outing is a good habit on any low-use collector vehicle.
