1942 Hudson Tire Fitment Guide

1942 Hudson vehicles use four different tire sizes, all on 16-inch wheels: 550-16, 600-16, 6.25-16, and 650-16. The 20T Series uses 550-16, the 20C Series, 20P & 21 and 28C Series use 600-16, the 22 Series and 24 Series use 6.25-16, and the 25 & 27 Series use 650-16. Where rim-width guidance appears in the available tire range, 550-16 products are shown on 3.25- to 4.00-inch rims, 600-16 on 4.00- to 4.50-inch rims, and 650-16 on 4.50- to 5.00-inch rims.

The practical takeaway is that a 1942 Hudson owner needs the exact series identification before choosing a tire. Every fitment here uses a 16-inch wheel, but the tire width changes across the model line, and that affects both appearance and wheel compatibility. If your car has had wheel changes over the years, compare the installed wheel to the tire's approved rim-width range before settling on a replacement size.

On a 1942 Hudson, 600-16 is a traditional numeric bias-ply size. The 6.00 portion is the nominal section width in inches, and the 16 identifies the wheel diameter in inches. Within the 1942 Hudson lineup, that size applies to the 20C Series, 20P & 21 and the 28C Series, and available examples come in both blackwall and wide whitewall forms.

That size marking matters because it reflects an older tire-sizing system rather than a modern metric radial code. Owners comparing reproduction tires will notice that some 600-16 choices also include added load or speed markings, while others retain a more straightforward period-style designation. Staying with 600-16 preserves the correct basic width and wheel diameter for the Hudson series that used it.

No, 1942 Hudson models do not all use the same tire size. The lineup is split across four sizes: 550-16, 600-16, 6.25-16, and 650-16, depending on the specific series. Some Hudson models share a size with one other series, but none of the four sizes runs across the entire 1942 Hudson range.

That difference means a tire choice should start with the vehicle's series tag or other reliable model identification, not just the Hudson badge and model year. The fact that all four sizes mount on 16-inch wheels can make old replacements seem interchangeable at a glance, but the correct width still needs to match the series and the wheel. That is especially important on prewar cars where originality and stance are part of the vehicle's character.

1942 Hudson tire options include both blackwall and wide whitewall sidewall styles, depending on the size and brand. The 600-16 range includes blackwall and wide whitewall choices, 550-16 is also available in both blackwall and wide whitewall, and 650-16 follows the same pattern. That gives owners flexibility across much of the Hudson lineup without changing the underlying size or bias-ply construction.

For a prewar American car like a 1942 Hudson, sidewall appearance has a major effect on the finished look. Wide whitewalls usually suit a more formal restoration presentation, while blackwalls often fit a plainer factory look or a more restrained driver-oriented presentation. If show authenticity is a concern, compare your chosen sidewall style against period photos, factory literature, and the standards used by Hudson clubs or event judges.

Several brands cover the 1942 Hudson fitment range. In 600-16, available brands include BFGoodrich, Coker Classic, Avon, and Firestone. In 550-16, the range includes Excelsior, Avon, BFGoodrich, and Firestone. In 650-16, available brands include BFGoodrich, Coker Classic, Firestone, and Garfield.

Brand choice on a 1942 Hudson usually comes down to the exact size you need, the sidewall appearance you want, and whether you prefer a more American-style prewar presentation or a particular tread and branding character. Because each size has its own brand mix, it is smart to settle the fitment first and then compare the brands offered in that specific size rather than assuming every brand appears across the whole Hudson lineup.

In 600-16 for a 1942 Hudson, BFGoodrich and Firestone both offer bias-ply tires with a 16-inch rim diameter and a 4.00- to 4.50-inch rim-width range. Both list a 1400-pound maximum load at 32 psi in the examples shown, but the sidewall presentation differs: BFGoodrich is offered with a 3.50-inch whitewall, while Firestone is offered with a 3.25-inch whitewall. The listed weights also differ, with BFGoodrich around 21 pounds and Firestone around 24 pounds in the products shown.

That makes the comparison more about visual preference and brand character than a major change in fitment. A restorer trying to match a certain whitewall proportion may care about the difference between a 3.25-inch and 3.50-inch stripe, while another owner may focus more on period brand appearance. Either way, both stay within the correct 600-16 bias-ply framework for the Hudson series that use that size.

Available rim-width guidance for 1942 Hudson tires varies by size. In the currently covered range, 550-16 products are shown for 3.25- to 4.00-inch rims, 600-16 products for 4.00- to 4.50-inch rims, and 650-16 products for 4.50- to 5.00-inch rims. All of those fitments use 16-inch wheel diameters, but the approved wheel width broadens as the tire gets wider.

That matters because a tire can share the correct 16-inch diameter and still be a poor match for the wheel if the rim is too narrow or too wide. Before fitting replacement tires to a 1942 Hudson, measure the actual wheel or confirm the wheel specification through a trusted service source. That step is especially worthwhile on cars that may have had wheels swapped during decades of repair or storage.

The available 1942 Hudson tire sizes are presented as traditional bias-ply fitments, but the individual listings do not carry a single universal tube marker across every product in every size. Because of that, inner-tube requirements should be confirmed against the exact tire being considered and the wheel it will be mounted on. On a prewar 16-inch Hudson wheel, tube use is often part of the broader wheel-and-tire setup rather than a one-answer rule for every product.

The practical step is to look at the sidewall designation and mounting requirements for the exact 550-16, 600-16, 6.25-16, or 650-16 tire you plan to run. Original-style wheels, wheel condition, and the tire's own construction details all influence the right setup. If your Hudson still uses original rims, a tire installer familiar with prewar wheels can help confirm whether tubes, flaps, stems, or other period-correct hardware should be part of the installation.

Original 1942 Hudson wheels can only be used with all tire sizes if the wheel matches both the shared 16-inch diameter and the correct rim width for the size in question. Every listed 1942 Hudson tire size mounts on a 16-inch wheel, but the approved rim-width ranges differ where published: narrower wheels suit 550-16, mid-width wheels suit 600-16, and wider wheels suit 650-16. That means diameter compatibility alone is not enough.

Owners sometimes assume any 16-inch Hudson wheel can take any 1942 Hudson tire size, but width is the limiting factor. If your car still has its original wheels and original series-correct hardware, staying with the factory-type size is usually the simplest path. If wheels have been mixed between cars over time, confirm the wheel before mounting a tire just because it happens to share the same 16-inch bead diameter.

A stored 1942 Hudson should be kept away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that accelerate rubber aging. Bias-ply tires also benefit from a clean, dry surface under the car and periodic movement so they do not sit in one position for months at a time. If the car will be down for a long season, some owners use stands to reduce static load while keeping the suspension supported correctly.

Those habits matter on a prewar Hudson because older-style bias-ply construction is more prone to temporary flat-spotting after long stationary periods. Good storage conditions help preserve sidewalls, maintain shape, and reduce the chance of finding weather-checking just as the driving season begins. A simple routine of tire-pressure checks and occasional rolling can make a noticeable difference in how the car feels when it returns to the road.

Tires on a 1942 Hudson are usually judged more by age than by miles driven, because collector cars often see light seasonal use. A sound rule is to start evaluating tires closely once they are around five to seven years old and to treat roughly ten years as a serious replacement point, even if tread remains. The DOT or production date marking, along with visible cracking, hardening, and storage history, matters more than odometer mileage alone.

That approach fits the way many prewar cars are used: occasional drives, long idle periods, and a lot of time indoors. A Hudson that looks fine at a glance can still be riding on aged rubber that has lost flexibility and confidence on the road. If a tire's age is uncertain, replacing it is often the wiser move than trusting appearance alone on a car that may carry family or travel at open-road speeds.

Tires on a 1942 Hudson should be checked before every drive and looked over more carefully before longer outings or touring events. The key points are sidewall cracking, tread wear, cuts, bulges, pressure loss, and any sign that the tire has been rubbing or running unevenly. On older wheel-and-tire assemblies, the valve stem area also deserves a close look because age and inactivity can affect it as much as the tire itself.

Regular inspection is especially important on a collector Hudson because many issues show up after storage rather than after heavy mileage. A tire that held pressure last fall can still develop age-related problems over the winter. Catching those early is easier and cheaper than discovering them after the car is loaded for a show, tour, or long back-road drive.

A 1942 Hudson 20C Series, 20P & 21 used 600-16 tires, and bias-ply construction is the period-correct type for that prewar application. That aligns with broader American passenger-car practice of the era, when bias-ply tires were standard equipment and radial construction was not part of ordinary factory fitment. Original-equipment branding could vary by market, contract, and replacement history, so the clearest constants are size, construction, and era-correct appearance.

For restoration work, start with the right 600-16 bias-ply size and then choose the sidewall treatment that best matches the specific car's build and intended presentation. A blackwall can suit a more restrained factory look, while a wide whitewall may better fit a formal restoration style. If you are preparing the car for marque judging, compare against Hudson club guidance, factory literature, and period photography before finalizing the tire choice.

Correct tire fitment matters on a 1942 Hudson because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall treatment immediately. A car shown with the wrong series-specific size, or with a sidewall style that does not suit the restoration goal, can look visibly off even before anyone studies finer trim details. On prewar cars, tire proportions are a significant part of stance and authenticity.

That does not always mean every event expects the exact same standard, but it does mean a 1942 Hudson should be fitted thoughtfully if originality is part of the goal. Owners pursuing points judging should confirm the proper size for their exact series and review whether blackwall or wide whitewall is appropriate for the car's market presentation. Hudson clubs and event rulebooks are the best final check for show-specific expectations.

In 650-16 for a 1942 Hudson, BFGoodrich and Firestone are both bias-ply 16-inch offerings built for 4.50- to 5.00-inch rims. Both examples shown list a maximum load capacity of 1580 pounds at 32 psi, but they differ in sidewall presentation and listed weight. BFGoodrich appears with a 3.75-inch whitewall at about 24 pounds, while Firestone is shown as a blackwall at about 23 pounds.

That means the choice is less about basic fitment and more about restoration presentation. An owner of a 25 or 27 Series Hudson trying to achieve a strong prewar whitewall look may lean one way, while a blackwall presentation points another way. Because both remain within the correct 650-16 bias-ply category, the final decision usually comes down to appearance and how closely you want the tire to support the car's intended finished style.

1942 Hudson tires can be suitable for highway driving when they are the correct size, in sound condition, and used within their intended construction and speed limits. The available 550-16 range includes an Avon 80L example, where L corresponds to 75 mph, and the 600-16 range includes an Avon 93H example, where H corresponds to 130 mph. Most of the fitments in this Hudson lineup are traditional bias-ply products, so the tire's condition and the car's overall mechanical health matter just as much as the size stamped on the sidewall.

A prewar Hudson's brakes, steering, suspension, and age-related mechanical condition usually become the real limiting factors well before a properly maintained reproduction tire reaches its rated ceiling. Owners should think in terms of stable, conservative touring rather than treating a speed symbol as a target. If the car has been inactive for years, a full mechanical inspection should come before any sustained highway use.

Inflation pressure for 1942 Hudson tires should follow the correct guidance for the exact size and tire being used rather than copying one pressure across the whole lineup. Some available examples list rated load-and-pressure figures, including 600-16 at 1400 pounds at 32 psi, 550-16 examples at up to 840 pounds at 32 psi or 992 pounds, and 650-16 at 1580 pounds at 32 psi. Those figures describe tire capability, not automatically the factory running pressure for every Hudson application.

The best practice is to start with the vehicle's original Hudson recommendation if you have reliable literature for your exact series, then compare that with the reproduction tire maker's published guidance for the tire you chose. Pressure affects ride, wear, and handling feel on a bias-ply prewar car, so avoid guessing or borrowing numbers from another size. Keeping all four tires even and checking them when cold is just as important as the pressure target itself.

Before a longer drive in a 1942 Hudson, inspect each tire for cracking, tread separation, cuts, bulges, uneven wear, and correct cold inflation pressure. Check the valve stems, look over the spare, and make sure the tire size on the car matches the proper fitment for the series. Because these are prewar-style bias-ply applications, it is also wise to make sure the tires have not developed flat spots or pressure loss during storage.

Tire condition is only one part of touring readiness on a 1942 Hudson, but it is one of the easiest things to verify before heading out. A careful pre-drive inspection can reveal age-related issues that might not be obvious once the car is moving. Pair the tire check with a broader inspection of brakes, steering, cooling, and wheel fasteners so the car is ready for the kind of measured, enjoyable road use these Hudsons suit best.
