1930 Whippet Tire Fitment Guide

1930 Whippet vehicles use two tire sizes: 28X4.75 and 475-19, and both are associated with the 1930 Whippet 96A. The 28X4.75 size is an antique diameter-by-section bias-ply fitment, while 475-19 is a numeric bias-ply fitment. The listed 475-19 products mount on 19-inch rims and call for a 3-inch rim width, while 28X4.75 belongs to a different size family with a different rim diameter.

That means a 1930 Whippet owner should not assume year and make alone are enough to choose a tire. Start by confirming the exact size marked on the old tire, the wheel diameter on the car, and whether the car has remained in original-style configuration. Once that is settled, choosing between blackwall and whitewall styling becomes much easier on the 475-19 side.

On a 1930 Whippet, 28X4.75 is an antique diameter-by-section size. The first number, 28, refers to the tire’s overall outside diameter, and the second number, 4.75, refers to its nominal section width. That is different from later sizing systems that identify the wheel diameter directly in the size code. It is a bias-ply format associated with early automotive tire conventions.

That distinction matters because a 28X4.75 tire is not simply another way of writing 475-19. The two sizes belong to different sizing systems and do not point to the same rim diameter. If your 1930 Whippet still carries older-style wheels or has been restored to a specific period configuration, matching the antique-format size correctly is an important first step before evaluating any replacement tire.

On a 1930 Whippet, 475-19 is a numeric bias-ply size. The 475 portion represents a nominal section width of 4.75 inches, written without a decimal in the traditional style, and the 19 identifies the wheel diameter in inches. The available 475-19 products here are bias-ply Goodyear tires built for 19-inch rims, with a listed rim width of 3 inches and a load figure of 900 pounds at 32 psi.

For a Whippet owner, 475-19 is the more straightforward modern-to-read size code because it includes the rim diameter directly. It is the correct path only if your car is actually fitted with 19-inch wheels. Once that is confirmed, the remaining choice is mostly about appearance, since both listed 475-19 options share the same construction and load specification but differ in sidewall style.

A 1930 Whippet should use 28X4.75 or 475-19 according to the wheel and fitment already on the car, not by personal preference alone. Both are bias-ply sizes, so this is not a bias-versus-radial decision. The important difference is that 28X4.75 is an antique diameter-by-section format and 475-19 is a numeric 19-inch rim size, which means they do not interchange as simple equivalents.

The practical approach is to verify the wheel diameter and the existing tire size before choosing either one. Owners restoring a car to a particular early presentation often pay close attention to whether the car was set up around an antique-format tire, while drivers working from an established 19-inch wheel setup should stay within the 475-19 family. Matching the wheel first prevents expensive fitment mistakes.

1930 Whippet tires in the listed 475-19 size are available in two sidewall styles: Blackwall and Wide Whitewall. Both are Goodyear Deluxe All-Weather bias-ply tires with the same published load capacity and rim requirements, so the visual treatment is the main difference between them. No alternate sidewall style is listed here for 28X4.75.

That gives 1930 Whippet owners a clear styling choice within the 19-inch fitment. Blackwall usually suits a more restrained, utilitarian presentation, while a wide whitewall creates a more formal period look that many restorers prefer on pre-war cars. If authenticity matters for a particular body style, market, or judging standard, compare the sidewall treatment against period photos and club guidance before finalizing the selection.

Goodyear is the listed brand currently available for 1930 Whippet in the 475-19 size. The available products are both from the Deluxe All-Weather line and differ by sidewall appearance rather than by construction, since both are bias-ply tires. No additional brand is listed here for the 1930 Whippet sizes covered on this page.

For a buyer, that means the brand decision is simple in 475-19 and the real choice shifts to sidewall style and confirming the correct fitment family. Goodyear is historically at home on an American car of this era, so the look is consistent with a traditional pre-war restoration approach. If your Whippet uses the alternate 28X4.75 sizing system, confirm that size first before comparing any available tire line.

The listed 1930 Whippet products in size 475-19 are built for a 3-inch rim width and mount on 19-inch rims. That gives a firm reference point for cars using the numeric 475-19 fitment. The alternate 28X4.75 size belongs to a different fitment family, so the 475-19 rim-width figure should not be carried over to it by assumption.

Before mounting any replacement tire on a 1930 Whippet, measure the wheel you actually have rather than relying on memory or model-year shorthand. A wheel that has been changed during an older restoration can alter what size fits correctly. Verifying rim width along with rim diameter is especially helpful on pre-war cars, where visual similarity between wheels can hide meaningful differences.

Original 1930 Whippet wheels cannot automatically be treated as compatible with both listed sizes, because 28X4.75 and 475-19 do not share the same rim diameter. The 475-19 size mounts on a 19-inch rim, while 28X4.75 is an antique-format size from a different wheel standard. That makes wheel identification the key step before any tire is selected.

If your Whippet has remained unchanged for decades, the wheel itself will usually tell you which path to follow once its diameter is confirmed. If the car has passed through multiple restorations, old wheels and old tires may not match each other as neatly as expected. Checking the actual wheel dimensions avoids mixing a correct-looking tire with an incompatible rim.

A 1930 Whippet should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Because the listed 1930 Whippet fitments are bias-ply tires, long static storage can encourage flat-spotting and age cracking sooner than many owners expect. Clean floors, stable temperatures, and avoiding prolonged contact with standing moisture all help preserve the tire casing and sidewalls.

For seasonal storage, slightly rolling the car periodically or using properly placed stands to reduce static load can be helpful if the car will sit for long stretches. Keep the tires inflated to an appropriate storage pressure rather than letting them sag. A Whippet that is stored well often feels better on the road later, because the tires are less likely to develop vibration or visible sidewall deterioration.

Tires on a 1930 Whippet usually age out before they wear out. On a collector car, a good rule is to begin evaluating tires closely once they reach about five to seven years of age and to treat roughly ten years as the point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on modern reproduction tires is the best starting point for establishing age.

That matters because a lightly driven pre-war car can look fine at a glance while the rubber has already hardened or started to crack internally. Mileage is often a poor guide on cars like a Whippet that spend more time parked than traveling. Regular age-based review is a safer habit than waiting for visible wear to make the decision for you.

Tires on a 1930 Whippet should be inspected before every drive and again before any longer outing. Look for sidewall cracking, weather checking, cuts, bulges, uneven wear, and any loss of pressure since the last use. Bias-ply tires especially benefit from frequent visual checks because collector cars often sit long enough for small age-related issues to become larger ones.

A more thorough inspection every few months is wise even if the car is seldom driven. Include the spare, because a roadside emergency is exactly when an old spare tends to reveal dry rot or pressure loss. If your Whippet uses older-style wheels or tube-type service, inspect the valve stems and hardware closely as part of the same routine rather than focusing on tread alone.

A 1930 Whippet 96A would have been fitted in the bias-ply era, and the two sizes associated here with that model are 28X4.75 and 475-19. Both reflect period-correct construction for a 1930 American compact car. Original-equipment branding could vary by market, dealer supply, and replacement history over the car’s life, so the most reliable authenticity anchors are the size, construction type, and sidewall presentation rather than assuming one universal brand.

For a careful restoration, treat those size families as the first authenticity checkpoint and then compare your car against factory literature, surviving original examples, and Whippet or Willys-Overland club knowledge. A judge or knowledgeable enthusiast is more likely to notice an incorrect size system or modern-looking sidewall than to focus on minor cosmetic differences elsewhere. Getting the tire format right helps the entire car sit and read correctly.

Correct tire fitment matters a great deal when showing a 1930 Whippet, especially in restoration classes that value period accuracy. Judges and knowledgeable marque enthusiasts often notice whether the car is wearing the right size family, correct bias-ply construction, and an era-appropriate sidewall style. A visibly modern substitute or an incorrect size convention can change the stance and overall impression of a pre-war car even before finer details are examined.

That does not mean every event uses identical standards, but tire appearance is one of the most immediate visual cues on a finished restoration. A blackwall versus wide whitewall decision can also influence how authentic the car feels for a given presentation. If competitive judging is the goal, compare your planned fitment with event rules, period photos, and marque-club guidance before committing to a final tire style.

For a 1930 Whippet in 475-19, the Goodyear Deluxe All-Weather Blackwall and the Goodyear Deluxe All-Weather 2.875 inch Whitewall share the same basic specification: both are bias-ply tires, both fit 19-inch rims, both call for a 3-inch rim width, both weigh 15 pounds, and both carry a listed maximum load of 900 pounds at 32 psi. The clear difference is the sidewall treatment.

That makes this a styling and presentation choice rather than a casing or load-capacity decision. The Blackwall reads more restrained and functional, while the 2.875-inch whitewall creates a more formal pre-war look that many restorers associate with upscale period presentation. If your Whippet is being finished to match a particular historical photo or show standard, the sidewall appearance is the factor to compare most closely.

1930 Whippet tires can be used on modern roads when they are the correct size, in sound condition, and operated within the limits of both the tire and the car. The listed 1930 Whippet products here are bias-ply tires, which deliver a period-correct driving character rather than modern radial behavior. On a car from 1930, braking, steering, suspension design, and overall mechanical condition are often as important to highway confidence as the tire itself.

The practical takeaway is to think of the whole vehicle as a system. A fresh, properly fitted bias-ply tire helps, but it does not turn a pre-war car into a modern highway machine. Short test drives, conservative speeds, and a thorough mechanical check before regular road use are wise habits for any Whippet owner planning to drive beyond local show or parade duty.

For 1930 Whippet tires in size 475-19, the listed maximum load figure is 900 pounds at 32 psi. That number is a load-and-pressure rating for the tire itself, not automatically the everyday running pressure every Whippet should use under all conditions. Inflation pressure on a pre-war car should be checked against the original owner’s literature when available and then balanced with the tire manufacturer’s specifications for the reproduction tire being used.

Do not transfer the 475-19 pressure figure over to 28X4.75 by guesswork, because the sizes belong to different fitment systems. The best approach is to start with the specifications tied to the exact tire on the exact wheel you have. Once the car is on the road, monitor wear pattern, ride quality, and pressure retention to make sure the setup is behaving as expected.

Before a longer drive in a 1930 Whippet, inspect each tire for visible cracking, cuts, bulges, tread separation, and proper inflation, and do the same for the spare. Confirm that the tire size on the car matches the wheel diameter actually fitted, since 28X4.75 and 475-19 are not interchangeable. A pre-trip check should also include valve stems, wheel hardware, and any sign that an older tire has started to lose its shape after storage.

Tires are only one part of the readiness picture on a 1930 automobile. Brake adjustment, wheel bearings, steering play, cooling condition, and fuel-system reliability all deserve attention before you ask the car to run farther than usual. A Whippet that passes a careful driveway inspection is far more likely to give a calm, enjoyable outing than one rushed onto the road after a long sit.
