1932 Cunningham Tire Fitment Guide

1932 Cunningham vehicles use one tire size across the model range: 750-18. The 1932 Cunningham 8 uses that size on an 18-inch rim, and the available products include bias-ply options built for different visual styles and wheel applications. Firestone versions are built around a 4-inch rim, while the Deka truck-type version is intended for wider 6.00- to 6.50-inch rims.

That means the size choice itself is straightforward, but wheel confirmation still matters before you settle on a specific tire. A 1932 Cunningham owner should verify the actual wheel on the car, especially if the vehicle has been restored, re-bodied, or fitted with non-original wheels at some point in its life. Once the wheel is confirmed, the remaining decision is usually blackwall versus whitewall presentation and whether you want a passenger-car style tire or a heavier-duty truck-type application.

On a 1932 Cunningham, 750-18 is a numeric bias-ply size. The 7.50 refers to the nominal tire section width in inches, and the 18 refers to the wheel diameter in inches. That naming style is typical of the period and differs from later alphanumeric and metric tire sizing systems.

Understanding that code helps you avoid confusing wheel diameter with overall tire height or mixing pre-war numeric sizing with later formats that look similar at a glance. When shopping for a 1932 Cunningham tire, the important takeaway is that every correct option in this year and make stays in the bias-ply family and mounts on an 18-inch wheel, but the sidewall treatment and wheel-width suitability can still differ from one product to another.

Yes. The 1932 Cunningham model range covered here uses the same 750-18 tire size, and the 1932 Cunningham 8 is the model associated with that fitment. There is no split in size by model for this year and make, which is not always the case with pre-war luxury automobiles that could vary by chassis or body style.

That shared fitment simplifies research because you do not need to sort among several factory tire sizes before narrowing down products. The practical work comes afterward: choosing the sidewall style that suits your restoration, making sure the wheel width matches the intended tire, and checking whether the car is being prepared for judged presentation, touring, or occasional local driving. Those details matter more here than model-to-model fitment differences.

1932 Cunningham tires in 750-18 are available in blackwall, wide whitewall, and double-whitewall styles. Firestone offers all three visual treatments in this size, while Deka appears here as a blackwall truck-type bias-ply option. All of them stay within an appropriate pre-war bias-ply construction, but they create very different visual impressions on the car.

A blackwall usually suits a more restrained, formal look and is often favored when authenticity is interpreted conservatively. Whitewall choices add more visual emphasis and can dramatically change how a large luxury car sits and presents at a show. Before choosing a sidewall style for a 1932 Cunningham, it is wise to compare your car’s body style, market history, and restoration goals with period photos or marque-club guidance so the tire complements the car rather than overpowering it.

Firestone and Deka both offer 750-18 tires for 1932 Cunningham fitment. Firestone’s options are passenger-car-style bias-ply tires in blackwall, wide whitewall, and double-whitewall versions, while Deka’s offering is a bias-ply truck-type blackwall tire in the same nominal size. Both brands keep the fitment in an era-appropriate bias-ply construction rather than shifting into later radial sizing.

Brand choice on a 1932 Cunningham usually comes down to how you want the car to appear and how closely the product matches the wheel and use case. An owner pursuing a luxury-car presentation may lean toward a Firestone sidewall style that suits the car’s character, while someone addressing a specific wheel application may evaluate the Deka option differently. The important step is comparing the tire’s intended rim width and overall character with the actual wheel and purpose of the car.

For a 1932 Cunningham, the Firestone 750-18 options are passenger-car bias-ply tires rated at 1930 pounds at 40 psi and built around a 4-inch rim, with blackwall, wide whitewall, and double-whitewall styles available. The Deka 750-18 is a bias-ply truck-type tire rated at 2540 pounds at 65 psi and intended for a wider 6.00- to 6.50-inch rim. Weight also differs, with the Firestone versions listed from 30 to 39 pounds and the Deka at 31 pounds.

Those differences matter because the tires are not simply cosmetic variations of the same product. A 1932 Cunningham owner should think first about wheel width and the car’s intended presentation before comparing appearance alone. The Firestone family fits the traditional luxury-car restoration conversation more naturally, while the Deka version should be evaluated in the context of a wheel setup that actually matches its wider rim requirement and truck-type construction.

Rim width depends on the specific 750-18 tire chosen for a 1932 Cunningham. Firestone 750-18 bias-ply tires in this fitment are built around a 4-inch rim, while the Deka 750-18 truck-type bias-ply tire is intended for a 6.00- to 6.50-inch rim. Even though the size code is the same, the wheel-width requirement is not identical across every product in the size.

That makes wheel verification one of the most important checks before ordering a 1932 Cunningham tire. Owners of restored cars should not assume that every 750-18 product is interchangeable simply because it shares the same nominal size and wheel diameter. Measuring the actual wheel, checking whether the car still carries its original type of rim, and matching the tire to that wheel will help avoid a setup that looks wrong or mounts improperly.

The available 1932 Cunningham 750-18 products are listed as bias-ply tires without tubeless markings in the size field. On a pre-war 18-inch wheel application like a 1932 Cunningham, owners commonly treat tube fitment as part of the overall wheel-and-tire setup, especially when using original-style rims and period-correct construction. The tire itself is only one part of that equation.

Inner-tube decisions should be made with the wheel design in mind rather than by size code alone. If your 1932 Cunningham retains original or original-style rims, confirm the wheel condition, valve-stem provision, and tube requirement before mounting tires. This is especially important on cars that have sat for long periods or have had older restorations, since tire replacement is an ideal time to inspect the full wheel, flap, and tube arrangement together.

A 1932 Cunningham should be stored in a cool, dry, dark environment away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that accelerate rubber aging. Bias-ply tires are especially prone to flat-spotting during long static periods, and pre-war luxury cars place substantial weight on their tires even when parked. Clean floors and stable temperatures help preserve both the tire casing and the sidewall appearance.

For a collector car that is not driven often, periodic movement is important so the same part of the tire is not carrying the load month after month. Some owners also use stands or adjust storage practices to reduce prolonged stress, but the car should still be supported carefully and safely. A 1932 Cunningham with whitewalls also benefits from routine cleaning with gentle products so the sidewall remains presentable without exposing the rubber to harsh chemicals.

Tire life on a 1932 Cunningham is usually governed more by age than by mileage. Collector vehicles often cover limited annual miles, so the key benchmarks are regular inspection after about five to seven years and serious replacement consideration as tires approach roughly ten years from their date of manufacture, regardless of remaining tread. Sidewall age, casing condition, and storage history matter more than odometer readings alone.

That is especially true for a pre-war car, where the tire may look acceptable from a distance but still have age-related hardening or cracking that affects serviceability. Owners should check the date code on the tire where applicable, monitor changes in ride quality, and evaluate any stored spare with the same care as the four tires on the ground. A low-mile 1932 Cunningham can still need fresh tires if the current set has simply aged out.

Tires on a 1932 Cunningham should be inspected before every drive and again before any longer outing or event. Look for sidewall cracking, cuts, bulges, irregular tread wear, pressure loss, and any sign that the tire has been sitting under load too long. On older wheel systems, the valve area and any tube-related components also deserve attention during routine checks.

Frequent inspection matters because a collector car may spend long periods parked and then be asked to cover substantial distance in a single day. A brief walkaround can catch problems early and helps you decide whether the car is ready for local use, a tour, or transport to a show. If the 1932 Cunningham has recently emerged from storage, increase the level of inspection and include the spare so the whole tire package is road-ready.

A 1932 Cunningham 8 would have been fitted in a bias-ply tire format, which was the standard construction for American luxury cars of the period. The available 750-18 fitment aligns with that pre-war construction style and keeps the car in the correct tire family for an authentic restoration approach. Original-equipment branding could vary by market, chassis delivery, or restoration history, so construction type and size are the more reliable starting points.

For most owners, the practical goal is to stay with the correct 750-18 bias-ply format and then refine the choice through sidewall style and wheel compatibility. If your Cunningham is being restored for a particularly exacting standard, period photographs, factory literature, and marque-club expertise are the best way to narrow down whether a blackwall or whitewall presentation is most appropriate for the individual car. That approach keeps the tire choice grounded in the car’s historical context.

Correct tire fitment matters significantly when a 1932 Cunningham is judged for authenticity. On a pre-war luxury car, judges and knowledgeable enthusiasts will notice whether the tire uses an era-appropriate size, proper bias-ply construction, and a sidewall treatment that suits the vehicle’s original character. A visibly modern construction or a sidewall style that looks out of period can change the overall impression even if the car otherwise presents well.

That does not mean every event applies the same standard, but tire choice is never a trivial detail on a car of this stature. If your Cunningham is intended for concours use, verify not just the 750-18 size but also whether blackwall, wide whitewall, or double-whitewall presentation best matches the car’s restoration theme. Marque clubs and event rulebooks remain the best guides for show-specific expectations beyond basic fitment correctness.

For a 1932 Cunningham, blackwall and whitewall 750-18 tires share the same basic bias-ply construction and wheel diameter, but they present the car very differently. Blackwall versions create a more restrained and formal appearance, while the available wide whitewall and double-whitewall Firestone options add significantly more visual emphasis. The choice is less about fitment and more about period presentation and restoration intent.

Large pre-war luxury cars can carry either look convincingly, but the right answer depends on how your individual Cunningham is being restored and shown. A sober, chauffeur-era aesthetic often points owners toward blackwalls, while a more prominent white sidewall can suit a formal open or closed car presented with more visual flourish. Reviewing surviving factory imagery and consulting Cunningham specialists can help you choose a sidewall style that feels historically natural rather than simply dramatic.

1932 Cunningham tires in this fitment are available as bias-ply products, and the listed examples do not include modern speed-rating letters in the size marking. That means the tire choice should be approached in the context of a pre-war automobile whose braking, steering, suspension, and overall road manners are very different from those of a modern car. On a well-sorted car, normal touring use is often limited more by the vehicle itself than by chasing modern interstate expectations.

Highway suitability depends on the full condition of the 1932 Cunningham, not just fresh rubber. Before any sustained road use, confirm tire condition, inflation, wheel integrity, steering play, brake performance, and how long the car has been out of storage. A carefully prepared pre-war luxury car can be enjoyable on the road, but it should be driven within the limits of its design, its tire construction, and the realities of modern traffic.

Inflation pressure for a 1932 Cunningham depends on the specific 750-18 tire selected. The available Firestone 750-18 options are listed with a maximum load of 1930 pounds at 40 psi, while the Deka 750-18 truck-type tire is listed at 2540 pounds at 65 psi. Those figures are product ratings, not a universal instruction to run every 1932 Cunningham tire at the same pressure.

The right approach is to start with the vehicle manufacturer’s recommended operating pressure if you have reliable period literature, then compare it with the tire maker’s rated specifications for the exact product you are using. Pressure should never be copied from one 750-18 tire to another without checking the product itself, especially when one version is a passenger-car tire and another is a truck-type casing. Matching pressure to the exact tire and wheel setup is essential.

Before a longer drive in a 1932 Cunningham, inspect all five tires for age cracking, cuts, bulges, irregular wear, and proper inflation, and make sure the spare is as serviceable as the four tires on the ground. Check the valve stems and, where applicable, the condition of any tube-related components during mounting or service. Tire readiness should be treated as one part of a broader mechanical review on a car from this era.

A longer outing is also the right time to confirm wheel security, brake feel, steering response, fluid levels, and whether the car has recently been exercised enough to trust its systems under sustained use. Pre-war cars reward preparation, and tires are one of the easiest places to prevent trouble before it starts. If anything about the tire age, wheel condition, or ride behavior seems questionable, address it before asking the car to cover real distance.
