1960 Alfa Romeo sat at an important point in the marque’s postwar evolution, balancing sporting character with sophisticated European road manners across sedans and compact coupes. The lineup ranged from the larger 1900 to the nimble Giulietta and Sprint, and tire choice follows those family differences closely. Three models are covered here, using two distinct radial sizes rather than one universal fitment across the full year and make. The practical first step is to confirm whether you have a 1900 or a Giulietta-based car, because that determines whether you need the millimetric 165R400 fitment or the 15-inch 155R15 size before you compare individual tire styles.
Which Tire Size Is Right for Your 1960 Alfa Romeo
Two tire sizes cover 1960 Alfa Romeo vehicles, and they vary by model rather than fitting the entire range interchangeably. The main decision starts with identifying the correct model, because the 1900 uses a different rim diameter from the Giulietta and Sprint. Understanding that distinction before choosing a product saves time and helps you match the tire to the correct wheel and vehicle.
165R400 is a millimetric radial size with a nominal section width of 165 millimeters and a 400mm rim diameter, and it is specific to the 1960 Alfa Romeo 1900 rather than the full Alfa Romeo range for the year. Michelin offers it in both Narrow Whitewall and Blackwall form, and the available versions are tube-type with an S speed rating, which carries a 112 mph ceiling. This is the size to choose when your 1900 still uses its original 400mm wheel format and you want a fitment that stays true to the car’s European character.
Year(s): 1960|Fit(s): Giulietta, Sprint|Construction: Radial|Rim: 15 in
155R15 is a metric radial with a nominal section width of 155 millimeters and a 15-inch rim diameter, a period European sizing convention that typically implies an approximately 80-series profile when no aspect ratio is written. This size is used by the 1960 Alfa Romeo Giulietta and Sprint, with Blackwall offerings from Firestone and Michelin; tube status and speed rating vary by product, ranging from no tube marking shown to TT and TL versions, with T-rated products capped at 118 mph and H-rated products capped at 130 mph. It suits Giulietta-based cars that need the correct 15-inch fitment while giving owners room to choose between traditional Michelin patterns and a more straightforward radial touring option.
Three Alfa Romeo model lines are covered for 1960. Tire size is not shared across the entire range, so identifying the exact model matters before choosing a tire: the 1900 uses a different wheel format from the Giulietta and Sprint. Select a model below to narrow the fitment history and see the tire choices that apply to that specific Alfa Romeo.
1960 Alfa Romeo 1900
The Alfa Romeo 1900 was the larger, more upscale member of the lineup, combining Italian sporting engineering with the practicality of a sedan-based platform. Its tires mount on 400mm rims rather than a conventional 15-inch wheel, which makes the 1900 a distinct fitment within the 1960 Alfa Romeo family.
The Giulietta helped define Alfa Romeo’s small-displacement sporting identity, delivering lively handling and a distinctly Italian approach to compact motoring. In 1960, its tire fitment mounts on 15-inch wheels, separating it from the larger 1900 and putting it with the smaller Giulietta-based cars in the range.
The Sprint carried the Giulietta mechanical spirit into a sleek coupe format, and it remains one of the most recognized Alfa Romeo shapes of the era. Like the Giulietta, it uses a 15-inch tire fitment, so the key is choosing the right 155R15 product style for the car’s intended use and presentation.
Six products are available across two tire sizes for 1960 Alfa Romeo vehicles. The 165R400 fitment has 2 Michelin radial choices in Narrow Whitewall and Blackwall, while 155R15 has 4 radial options from Firestone and Michelin in Blackwall form; tube requirements and speed ratings can vary between products within the same size.
These FAQs cover the split between 400mm and 15-inch Alfa Romeo fitments, how Michelin and Firestone options differ within the year, and what to check for storage, setup, authenticity, and regular road use on a collector car.
Size Basics & Fitment
What tire sizes fit 1960 Alfa Romeo vehicles?
1960 Alfa Romeo vehicles use two tire sizes across three model lines. The Alfa Romeo 1900 uses 165R400, while the Alfa Romeo Giulietta and Alfa Romeo Sprint use 155R15. The 165R400 mounts on 400mm rims, with rim-width ranges of 4.50 to 6.00 inches and 6.0 to 7.0 inches depending on the tire. The 155R15 mounts on 15-inch rims, with available rim-width guidance of 4.00 to 5.50 inches on products where that specification appears.
That means year and make alone are not enough for 1960 Alfa Romeo tire selection. A 1900 owner needs to verify that the car still wears its correct 400mm wheels, while Giulietta and Sprint owners should focus on the 15-inch radial choices. Once the model is confirmed, the next step is comparing sidewall appearance, tube type, and speed rating within the correct size rather than trying to interchange the two fitments.
What does 165R400 mean on a 1960 Alfa Romeo tire?
On a 1960 Alfa Romeo, 165R400 is a millimetric radial size. The 165 refers to nominal section width in millimeters, the R indicates radial construction, and the 400 refers to a 400mm rim diameter rather than a 15-inch or 16-inch American-style wheel size. In this year and make, that size applies to the Alfa Romeo 1900. Available versions carry an 87S marking, with S representing a 112 mph speed ceiling.
The important takeaway is that 165R400 is not interchangeable with 155R15 even though both are period European radial sizes. A 1900 owner should confirm the wheel itself before ordering, because a true 400mm rim calls for a millimetric tire, not a nearby inch-based substitute. That check is especially important on restored cars, where wheels may have been changed sometime in the car’s life.
Do all 1960 Alfa Romeo models use the same tire size?
No, 1960 Alfa Romeo models do not all use the same tire size. The Alfa Romeo 1900 uses 165R400, while the Alfa Romeo Giulietta and Alfa Romeo Sprint use 155R15. Both are radial fitments, but they mount on different rim diameters and serve different parts of the model range. The separation follows the larger 1900’s more substantial chassis and the smaller Giulietta-based cars’ 15-inch wheel setup.
That split matters because it changes the starting point for tire selection. If you own a Giulietta or Sprint, you can compare 155R15 choices directly by speed rating, tube type, and brand character. If you own a 1900, the first concern is preserving the correct 400mm fitment. Identifying the exact model before shopping prevents one of the most common vintage European tire mistakes: confusing a millimetric rim with a conventional inch rim.
Buying the Right Tire
What sidewall styles are available for 1960 Alfa Romeo tires?
1960 Alfa Romeo tire sidewall styles vary by size. The 165R400 used on the Alfa Romeo 1900 is available in both Narrow Whitewall and Blackwall form from Michelin. The 155R15 used on the Alfa Romeo Giulietta and Alfa Romeo Sprint is available in Blackwall form. That sidewall spread fits the era well, since many European sporting cars of the period were most often seen with blackwall tires, while some larger touring sedans could also wear a restrained whitewall treatment.
For an owner concerned with appearance, sidewall choice can change the whole visual character of the car even when the tire size is correct. A 1900 with a narrow whitewall can lean toward a more formal touring presentation, while blackwalls keep a cleaner European sporting look. Giulietta and Sprint owners looking for period-appropriate presentation will usually stay within the available blackwall options and then compare brand, tube type, and speed rating details.
What brands make tires for 1960 Alfa Romeo vehicles?
Two brands cover 1960 Alfa Romeo fitments here: Michelin and Firestone. Michelin supplies both 165R400 products for the Alfa Romeo 1900 and also offers multiple 155R15 choices for the Alfa Romeo Giulietta and Alfa Romeo Sprint, including Michelin X, XAS, and XAS-FF patterns. Firestone appears in the 155R15 size with the F560 Radial. All of these are radial tires, but they differ in sidewall presentation, tube status, and speed rating details.
Brand choice on a 1960 Alfa Romeo often comes down to the kind of ownership experience you want. Michelin has especially strong period relevance for European millimetric and early radial fitments, which matters to owners who want a distinctly continental feel and presentation. Firestone gives Giulietta and Sprint owners another 15-inch radial path to consider, especially when straightforward blackwall appearance and a conventional touring-style radial are part of the plan.
What is the difference between Michelin X and Michelin XAS for the 1960 Alfa Romeo?
For a 1960 Alfa Romeo in 155R15, Michelin X and Michelin XAS differ in both speed rating and tube configuration. Michelin X appears as 155R15 82T TL, making it a tubeless T-rated tire with a 118 mph speed ceiling. Michelin XAS appears as 155HR15 82H TT, making it a tube-type H-rated tire with a 130 mph speed ceiling. Michelin XAS-FF adds another variation in the same family as a 155HR15 82H TL version.
Those distinctions matter more than the brand name alone. A Giulietta or Sprint owner should check whether the wheel and intended setup favor a tube-type or tubeless product, then decide whether the T or H speed category better suits the car’s use and the owner’s preferences. Since both versions are blackwall radials in the same nominal size, the decision is less about overall fit and more about setup details and the character of the individual Michelin pattern.
Fitting & Setup
What rim width do 1960 Alfa Romeo tires require?
Rim width guidance for 1960 Alfa Romeo tires depends on the size. In 165R400, one Michelin version fits 4.50 to 6.00-inch rims and another fits 6.0 to 7.0-inch rims, both on 400mm diameter wheels. In 155R15, the available rim-width guidance is 4.00 to 5.50 inches on products where that measurement appears. Rim diameter still has to match the tire exactly, so a 400mm tire belongs on a 400mm rim and a 15-inch tire belongs on a 15-inch rim.
That makes wheel verification an essential part of vintage Alfa Romeo tire selection. The 1900’s millimetric fitment can catch owners off guard if the car has changed hands several times, while Giulietta and Sprint owners should compare their wheel width against the tire’s approved range before committing to a product. Matching both diameter and width helps preserve handling balance, bead seating, and the overall look of the car.
Do 1960 Alfa Romeo tires require inner tubes?
Inner-tube requirements for 1960 Alfa Romeo tires depend on the exact size and product. In 165R400 for the Alfa Romeo 1900, the available Michelin choices are tube-type, marked TT. In 155R15 for the Alfa Romeo Giulietta and Alfa Romeo Sprint, tube status varies by product: Michelin XAS is TT, Michelin X and Michelin XAS-FF are TL, and Firestone F560 does not carry a tube marking in the size description shown here.
That variation means tube choice should be confirmed after you identify both the tire and the wheel. A wheel originally designed for tube-type service may still call for a tube even when a tubeless tire is chosen, while some later wheel conditions may support a tubeless setup more naturally. On a vintage Alfa Romeo, the safest path is to treat the tire marking and the wheel design as a pair rather than assuming all products in the same nominal size are set up the same way.
Maintenance, Storage & Longevity
How should I store a 1960 Alfa Romeo when the tires are fitted?
A 1960 Alfa Romeo should be stored in a cool, dry, dark place with the tires kept away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that accelerate sidewall aging. Tire pressures should be maintained during storage, and the car should be moved periodically or supported in a way that reduces long-term static loading. Radial tires resist flat spotting better than many old bias-ply designs, but they still benefit from regular movement and clean, stable storage conditions.
Good storage practices preserve both appearance and road manners. On a seldom-driven Giulietta, Sprint, or 1900, neglected storage can age the tires long before tread wear becomes an issue. If the car will sit for months, inspect the contact patch and sidewalls before the next drive and keep the spare in the same protected environment, since collector-car spares often age quietly and are forgotten until they are needed.
How long do tires on a 1960 Alfa Romeo typically last?
Tires on a 1960 Alfa Romeo usually age out before they wear out, especially on collector cars that see modest annual mileage. A practical rule is to evaluate them closely once they reach five to seven years of age and to consider replacement around the ten-year mark regardless of remaining tread depth. The DOT or production date marking is the important reference point, not the restoration date or the number of miles driven since installation.
That age-based approach is especially important on lightly used European classics, where the car may feel fine at neighborhood speeds even as the rubber hardens and the casing ages. If a 1900, Giulietta, or Sprint is driven only for events and weekend outings, inspect the date codes now instead of assuming low mileage means long life. Time, heat cycles, and storage conditions matter more than odometer readings for most vintage tire decisions.
How often should tires on a 1960 Alfa Romeo be inspected?
Tires on a 1960 Alfa Romeo should be inspected before every drive and again before any longer outing. Look for sidewall cracking, tread separation, bulges, cuts, uneven wear, and pressure loss, and pay attention to valve stems as well. On tube-type products such as the 165R400 Michelin options and some 155R15 choices, the valve area deserves extra attention because slow leaks can appear there before other symptoms become obvious.
Frequent inspection is one of the simplest ways to protect an older Alfa Romeo. These cars are often driven intermittently, which means problems can develop while parked rather than while accumulating mileage. A quick walk-around before a drive can catch a low tire, aging sidewall, or damaged spare before it becomes a roadside issue, and it also gives you a moment to verify that pressures are still appropriate for the day’s route and load.
Restoration & Authenticity
What tires were originally fitted to the 1960 Alfa Romeo 1900?
A 1960 Alfa Romeo 1900 would have been associated with period-correct European radial or contemporary touring tire practice appropriate to its market and wheel specification, and the fitment here is 165R400 on 400mm rims. That millimetric format is the key authenticity clue, because it separates the 1900 from the 15-inch Giulietta-based cars. Michelin remains closely aligned with this style of European fitment, but original-equipment branding could vary by market and delivery history.
For restoration work, the most important point is preserving the correct size, rim format, and sidewall appearance for the car you actually have. A 1900 owner chasing strict authenticity should compare surviving literature, wheel markings, and marque-club guidance before choosing between blackwall and narrow whitewall presentation. That extra research matters more on a car with international delivery history, since export-market details could influence what judges or knowledgeable enthusiasts expect to see.
Does correct tire fitment matter for showing a 1960 Alfa Romeo?
Correct tire fitment matters a great deal when a 1960 Alfa Romeo is judged for authenticity. Judges and marque specialists commonly notice whether the car wears the right size, the right general construction for the era, and a sidewall style that matches the vehicle’s character and market presentation. On this year and make, the biggest red flag would be a mismatch between the 1900’s 400mm fitment and the 15-inch Giulietta and Sprint fitment, because that changes both appearance and correctness immediately.
Show standards can vary, so event-level expectations should always be confirmed before final assembly. A touring-class owner may accept a visually sympathetic radial with less concern for exact pattern lineage, while concours entrants usually benefit from researching period photos, factory literature, and Alfa Romeo club resources. Tire choice is one of the first details people see, and on a finely restored Italian car it can either support the whole presentation or quietly undermine it.
What is the difference between Michelin X Radial and Michelin X-Stop for the 1960 Alfa Romeo?
For the 1960 Alfa Romeo 1900 in 165R400, Michelin X Radial and Michelin X-Stop differ mainly in sidewall style, weight, and approved rim-width range. Michelin X Radial appears as a Narrow Whitewall tire weighing 17 pounds and fitting 6.0 to 7.0-inch rims. Michelin X-Stop appears as a Blackwall tire weighing 20 pounds and fitting 4.50 to 6.00-inch rims. Both carry an 87S TT size marking, so both are tube-type radials with the same S speed category.
That makes the choice more about wheel width and presentation than about broad fitment class. A 1900 owner with a narrower wheel may naturally be drawn to the X-Stop range, while an owner seeking a more formal period look may prefer the narrow whitewall X Radial if the wheel width supports it. Checking the actual wheel before choosing between the two is especially important on older restorations, where wheel swaps are not uncommon.
Safety & Road Use
Are 1960 Alfa Romeo tires safe for highway driving?
1960 Alfa Romeo tires can be appropriate for highway driving when they are in good condition, correctly fitted, and used within their speed rating. The 165R400 Michelin options carry an S rating, which corresponds to 112 mph. In 155R15, Michelin products appear with T and H ratings, corresponding to 118 mph and 130 mph, while some products do not show a speed letter in the same way. Those ratings are well above ordinary modern highway speeds.
Real-world safety on a 1960 Alfa Romeo still depends on much more than the tire alone. Brakes, suspension condition, steering play, wheel integrity, and alignment often matter more than the difference between one highway-capable radial and another in routine use. Before a longer trip, treat the tires as one part of the car’s overall roadworthiness and keep your cruising pace in line with the age, weight, and mechanical condition of the specific Alfa Romeo you are driving.
What inflation pressure should I use for 1960 Alfa Romeo tires?
Inflation pressure for 1960 Alfa Romeo tires should start with the factory vehicle recommendation, then be checked against the individual tire’s own load and pressure information where that is available. In 155R15, the Firestone F560 carries a maximum load figure of 1045 pounds at 44 psi. The 165R400 Michelin products and several Michelin 155R15 products do not show a load-and-pressure pair here in the same way, so pressure should not be borrowed from a different size or brand as a shortcut.
The key is to separate maximum pressure capability from the pressure the car actually needs in service. A collector Alfa Romeo may ride, steer, and wear better at a vehicle-appropriate pressure than at the tire’s maximum figure, especially when lightly loaded. Use the owner’s manual or a trusted Alfa Romeo reference for baseline settings, then confirm that your chosen tire’s construction, wheel type, and intended use all support that starting point.
What should I check before taking a 1960 Alfa Romeo on a longer drive?
Before a longer drive in a 1960 Alfa Romeo, inspect every tire for sidewall cracking, cuts, bulges, punctures, irregular wear, and stable pressure, and do not forget the spare. On tube-type applications such as the 165R400 products and some 155R15 choices, valve stems and any signs of slow leakage deserve special attention. Wheel condition matters too, especially on older European rims where corrosion, past repairs, or bead-seat damage can affect how well a tire performs on the road.
A smart pre-drive routine goes beyond the tires, but the tires are where the whole trip meets the road. If the car has been stored, roll it far enough to check for temporary flat spotting and verify that nothing feels unusual at low speed before joining faster traffic. That cautious first mile is often where a vintage Alfa Romeo reveals whether the tires, wheels, and chassis are truly ready for the kind of distance you have planned.
