The 1950 AC Saloon comes from a postwar British touring era when coachbuilt character, modest production, and mechanical refinement mattered as much as outright speed. Cars like this are often preserved for their distinctive presence and understated craftsmanship, which makes tire choice an important part of both appearance and road manners. This model uses a 550-17 bias-ply tire on a 17-inch rim, keeping the fitment firmly in period. Available choices stay within that traditional size while offering blackwall, wide whitewall, and double-whitewall presentations in the Silvertown Classic Bias Ply series. The real decision is how closely the tire's look should support the car's restoration style and intended driving use.
Which Tire Size Is Right for The 1950 AC Saloon
The 1950 AC Saloon uses one primary tire size: 550-17. It is a bias-ply fitment on a 17-inch rim, and the covered 2-Liter sub-model uses the same size, so the main decision is not between multiple primary fitments but between sidewall presentation and the kind of period-style look you want the car to carry.
A 550-17 is a vintage numeric bias-ply size in which the 5.50 designation refers to the tire's nominal section width in inches, while 17 indicates the wheel diameter it fits. On a 1950 AC Saloon, that keeps the tire format consistent with the car's original-era construction and visual character. In this size, BFGoodrich options are available in the Silvertown Classic Bias Ply series with blackwall, wide whitewall, and double-whitewall sidewall treatments. Choosing within 550-17 is mostly about matching the car's restoration style, wheel setup, and intended road presentation rather than changing to a different primary size.
Tire fitment is straightforward for the covered 1950 AC Saloon range. The 2-Liter uses the same 550-17 bias-ply size, so sub-model identification matters mainly as a final confirmation before selecting sidewall style and product details.

1950 AC Saloon 2-Liter
The 1950 AC Saloon 2-Liter uses the same 550-17 bias-ply fitment as the model core, keeping tire selection centered on a traditional 17-inch setup. That makes the choice more about period-style presentation, including blackwall or whitewall appearance, than about sorting through multiple primary sizes.
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.

Tire Size & Fitment
What tire size fits a 1950 AC Saloon?
The 1950 AC Saloon uses a 550-17 tire size. That is a vintage numeric bias-ply fitment, and the covered 2-Liter sub-model uses the same primary size, so there is not a second main fitment to sort through for this application.
The practical next step is confirming that the car still has the correct 17-inch wheel setup, especially if it has been restored or modified over the years. Once the wheel diameter is verified, the decision usually comes down to sidewall appearance and choosing a period-style bias-ply tire that suits the car's intended use and overall presentation.
What size rim does a 1950 AC Saloon use?
The 1950 AC Saloon uses a 17-inch rim with its 550-17 tire fitment. Matching the tire to the correct rim diameter is essential, because a vintage 17-inch tire is designed for a 17-inch wheel and should not be treated as interchangeable with nearby sizes.
Wheel diameter should be confirmed directly on the car before replacement, particularly on collector vehicles that may have changed hands several times. A car can look correct at a glance and still have different wheels fitted, so checking the actual wheel size helps avoid ordering the right-looking tire in the wrong diameter.
What does 550-17 mean on a 1950 AC Saloon?
On a 1950 AC Saloon, 550-17 is a vintage numeric bias-ply size. The 5.50 portion refers to the tire's nominal section width in inches, and the 17 refers to the wheel diameter in inches, which places the tire in a traditional postwar sizing system rather than a modern metric one.
That matters because modern buyers often expect a tire size to describe width, aspect ratio, and radial construction in one code. A 550-17 does not work that way, so the better approach is to keep the original-style size in focus first, then compare sidewall style, brand, and overall presentation within that established fitment.
Choosing the Right Tire
What should I consider when choosing a 550-17 tire for a 1950 AC Saloon?
Start with the confirmed primary fitment: 550-17 on a 17-inch wheel in bias-ply construction. For the 1950 AC Saloon, that keeps the tire aligned with the car's period character, so the main selection factors become sidewall appearance, series, and whether the tire suits a preservation-minded driver or a fuller restoration presentation.
A blackwall usually gives the most restrained look, while wide whitewall and double-whitewall versions create a stronger vintage visual statement. It also helps to confirm that the wheel itself is appropriate for the tire and that all four corners of the car share the same setup before settling on a final choice.
What sidewall styles are available for 1950 AC Saloon tires?
For the 1950 AC Saloon's 550-17 size, available sidewall styles include Blackwall, Wide Whitewall, and Double-Whitewall. Those choices stay within the same bias-ply size and tire series, so the sidewall treatment becomes one of the biggest visual differences between otherwise similar period-style tire options.
That makes sidewall selection an appearance decision as much as a fitment one. A blackwall tends to keep the car understated, while whitewall treatments draw more attention to the wheel opening and body lines, so the right choice depends on whether the car is being presented as a subtle driver or a more restoration-oriented showpiece.
What brands offer tires for the 1950 AC Saloon?
The available 550-17 fitment for the 1950 AC Saloon is offered here in BFGoodrich form, using the Silvertown Classic Bias Ply series. Within that brand and series, the major choice is not between different constructions or sizes, but between sidewall styles that change the car's finished look.
That means brand comparison is less central on this application than selecting the right presentation for the vehicle. Once the 17-inch wheel and 550-17 size are confirmed, the buying decision becomes more focused on whether a blackwall, wide whitewall, or double-whitewall best complements the car's restoration goals and visual balance.
Restoration & Appearance
Which tire should I choose for a period-style 1950 AC Saloon?
A period-style 1950 AC Saloon starts with the correct primary size and construction, which here means a 550-17 bias-ply tire on a 17-inch rim. That preserves the traditional sizing format and visual profile associated with a postwar saloon of this type, rather than shifting the car toward a more obviously modern tire presentation.
From there, the best choice depends on how the car is being presented. A blackwall can suit a restrained touring appearance, while wide whitewall or double-whitewall options create a more formal restoration-oriented look. If exact historical originality matters, it is worth comparing the tire appearance against marque references and period photos for the car.
Does correct tire fitment matter for a 1950 AC Saloon restoration?
Correct tire fitment matters because it influences both the stance of the 1950 AC Saloon and the way the finished restoration reads at a glance. Using the proper 550-17 bias-ply format helps maintain the car's period character in a way that a visibly different modern sizing convention often does not.
Fitment also affects practical details beyond appearance. A collector car should have its wheel diameter confirmed, and any long-stored rims should be inspected before mounting replacement tires. Once the basic fitment is right, sidewall style becomes the finishing touch that can either keep the restoration understated or give it a stronger vintage show-car presence.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1950 AC Saloon?
Yes, modifications can affect tire fitment on a 1950 AC Saloon even when the intended tire size remains 550-17. Changes such as aftermarket wheels, altered suspension height, brake conversions, or bodywork repairs can influence how a traditional bias-ply tire sits in the wheel opening and clears surrounding components.
That is why the actual wheel diameter and general wheel condition should be checked on the car before replacement tires are chosen. Clearance at full steering lock, suspension travel, and the relationship between the tire and fender edge are all worth reviewing on an older vehicle, especially if its history includes restoration work or non-original hardware.
What should I inspect before driving a 1950 AC Saloon on new tires?
Before driving a 1950 AC Saloon on new tires, inspect the wheels for damage or corrosion, confirm valve-stem condition, and make sure the tires are mounted in the correct 550-17 size on 17-inch rims. It is also smart to check for any obvious steering or suspension looseness that could affect how the car tracks on the road.
A collector car deserves a careful walk-around before its first longer trip. Tire pressure should be set appropriately, lug hardware should be secure, and the tires should be checked for proper seating and any early air loss after installation. A short shakedown drive can reveal vibration, pull, or clearance issues before more serious road use.
How should 550-17 tires on a collector 1950 AC Saloon be maintained?
550-17 tires on a collector 1950 AC Saloon should be maintained with regular pressure checks, routine visual inspection, and attention to age-related issues that can appear even when mileage stays low. Sidewall cracking, cuts, bulges, tread irregularities, and slow air loss all deserve prompt attention on a car that may spend long periods in storage.
Storage conditions matter almost as much as road use on an older collector vehicle. Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone-producing equipment helps protect the tires between drives. Even a well-kept set should be inspected before each outing, because time and storage can change tire condition long before tread wear becomes the issue.
