1930 Dodge sat in the heart of the American market, offering sturdy six-cylinder cars that appealed to practical buyers who still wanted style and substance in the early Depression era. By that year, Dodge had a reputation for durability, and its model range reflected the transition from late-1920s proportions into more modern 1930 body and chassis design. Tire choice across 1930 Dodge is model-specific rather than shared, with three model lines using six distinct sizes split between antique diameter-by-section markings and newer numeric bias-ply sizing. The first thing to confirm on a 1930 Dodge is the exact model, because the 6-Standard, DC, and DD each point you toward a different tire size and wheel diameter.
Which Tire Size Is Right for Your 1930 Dodge
Six tire sizes appear across 1930 Dodge vehicles, and they vary by model rather than being shared across the full range. Every size here is a bias-ply fitment, so the real decision starts with confirming whether you have a 6-Standard, DC, or DD and then matching the correct wheel diameter for that model. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 1930|Fit(s): 6-Standard|Construction: Bias Ply|Rim: 19-in rim
29X5.50 is an antique size that uses an overall diameter of 29 inches and a nominal 5.50-inch section width, and on the 1930 Dodge 6-Standard it is a bias-ply fitment specific to that model rather than universal across the year. No currently listed products appear in this size here, so sidewall-style and brand variation are not part of the buying decision at this level. This size matters most to restorers who want to follow the early-1930s diameter-based sizing convention used on the 6-Standard.
Year(s): 1930|Fit(s): 6-Standard|Construction: Bias Ply|Rim: 19 in
550-19 is a numeric bias-ply size in which 5.50 refers to the nominal section width and 19 is the wheel diameter in inches, and on 1930 Dodge it is specific to the 6-Standard. BFGoodrich offers this size in Blackwall and Wide Whitewall form, with listed load capacity of 1040 pounds at 32 psi and rim-width compatibility from 2.50 to 3.00 inches. Buyers usually choose this size when they want a widely recognized early-1930s numeric replacement format with a choice between a plainer blackwall look and a more formal whitewall presentation.
Year(s): 1930|Fit(s): DC|Construction: Bias Ply|Rim: 18-in rim
28X5.50 is an antique bias-ply size that expresses the tire by overall diameter and nominal section width, and on a 1930 Dodge it belongs to the DC model only. No currently listed products appear in this size here, so there is no sidewall-style or brand spread to compare within this format. This size is the one to consider when preserving the original older-style size convention used on the DC rather than converting to the corresponding numeric marking.
Year(s): 1930|Fit(s): DC|Construction: Bias Ply|Rim: 18 in
550-18 is a numeric bias-ply size where 5.50 is the nominal section width and 18 is the rim diameter in inches, and it is used on the 1930 Dodge DC rather than across the full Dodge line. Available offerings include Excelsior, Firestone, and BFGoodrich, with Blackwall, Wide Whitewall, and Double-Whitewall styles, plus listed load figures up to 1125 pounds at 32 psi and rim-width references ranging from 3.00 to 4.00 inches depending on the product. This is the practical choice for a DC owner who wants the more familiar numeric size format and the widest visible range of appearance options.
Year(s): 1930|Fit(s): DD|Construction: Bias Ply|Rim: 19-in rim
29X5.00 is an antique diameter-by-section bias-ply size, meaning the first number is the tire's overall diameter in inches and the second is its nominal section width, and on 1930 Dodge it is specific to the DD. No currently listed products appear in this size here, so there are no brand, sidewall, or load variations to compare within the page's product selection. This size mainly serves buyers focused on preserving the DD's period-correct pre-metric sizing language.
Year(s): 1930|Fit(s): DD|Construction: Bias Ply|Rim: 19 in
500-19 is a numeric bias-ply size in which 5.00 denotes nominal section width and 19 denotes rim diameter, and for 1930 Dodge it applies to the DD only. Excelsior and Firestone offer this size in Blackwall form, with one listed load figure of 895 pounds at 32 psi and rim-width references spanning 4.00 to 5.00 inches depending on the tire. DD owners typically look here when they want a numeric-size replacement path, including options with a more specialized vintage competition or dirt-track character.
Three 1930 Dodge models are covered here, and they do not all use the same tire sizes. The practical effect is straightforward: year and make alone are not enough, because the 6-Standard, DC, and DD each use their own pair of sizes tied to different wheel diameters. Select your model below to narrow the fitment history and see the tire choices that apply to it.
1930 Dodge 6-Standard
The 1930 Dodge 6-Standard represented Dodge's mainstream six-cylinder offering, aimed at buyers who wanted solid engineering and conservative value in a full-size passenger car. Its tires mount on 19-inch wheels, and the model is associated with both an antique 29X5.50 marking and a numeric 550-19 size depending on how you want to approach restoration and replacement format.
The 1930 Dodge DC sits in the same early-Depression Dodge family but follows its own fitment path, reflecting the model-specific wheel and tire sizing common in the era. Its tires mount on 18-inch wheels, with a choice between the antique-style 28X5.50 designation and the numeric 550-18 replacement format.
The 1930 Dodge DD is another distinct model line from the same year, and for tire purposes it needs to be treated separately rather than grouped with the other 1930 Dodges. It uses 19-inch wheels, paired with either the antique 29X5.00 sizing convention or the numeric 500-19 designation depending on the style of replacement being pursued.
Eleven products are available across three tire sizes for 1930 Dodge vehicles. 550-19 includes two BFGoodrich bias-ply options in Blackwall and Wide Whitewall; 550-18 includes seven bias-ply choices from Excelsior, Firestone, and BFGoodrich in Blackwall, Wide Whitewall, and Double-Whitewall styles; 500-19 includes two Blackwall bias-ply tires from Excelsior and Firestone. Confirm the exact size first, since product selection changes by model.
These FAQs sort out the model-by-model tire differences found across 1930 Dodge, explain antique versus numeric bias-ply sizing, and cover the setup, storage, road-use, and authenticity questions that matter most with an early-1930s collector car.
Size Basics & Fitment
What tire sizes fit 1930 Dodge vehicles?
1930 Dodge vehicles use six sizes across three model lines. The 6-Standard uses 29X5.50 and 550-19, the DC uses 28X5.50 and 550-18, and the DD uses 29X5.00 and 500-19. Wheel diameter is not the same across every 1930 Dodge model: the 6-Standard and DD use 19-inch rims in their numeric sizes, while the DC uses an 18-inch rim. Where current product fitment is listed, 550-19 fits 2.50 to 3.00-inch rims, 550-18 appears on products referencing 3.00 to 4.00-inch rims, and 500-19 appears on products referencing 4.00 to 5.00-inch rims depending on the tire.
That means a 1930 Dodge owner should identify the model before thinking about sidewall style or brand. The antique-style sizes and the numeric sizes are tied to the same model families, but they are not interchangeable across the full Dodge lineup for the year. If your car still wears older wheels or has been restored previously, confirm the actual rim diameter and compare the existing sidewall marking before choosing a replacement path.
What does 29X5.50 mean on a 1930 Dodge tire?
On a 1930 Dodge, 29X5.50 is an antique diameter-by-section size. The 29 refers to the tire's overall diameter in inches, while 5.50 refers to its nominal section width. That format predates the later numeric bias-ply convention and appears on the 1930 Dodge 6-Standard rather than across all Dodge models for the year. It is still a bias-ply tire format, but the way the size is written reflects an earlier period of tire sizing.
A buyer usually encounters 29X5.50 when preserving a more period-faithful look and sidewall marking on a 6-Standard. It is worth checking the tire currently on the car, because some early cars were later converted to the corresponding numeric style during older restorations or routine service life. Matching the existing wheel diameter and the style of sizing already used on the car helps keep the fitment and appearance consistent.
What does 550-19 mean on a 1930 Dodge tire?
On a 1930 Dodge, 550-19 is a numeric bias-ply size. The 5.50 indicates nominal section width and the 19 indicates wheel diameter in inches. For 1930 Dodge, that size applies to the 6-Standard and not to the DC or DD. Current offerings in 550-19 are bias-ply BFGoodrich tires, available in both Blackwall and Wide Whitewall styles, with listed load capacity of 1040 pounds at 32 psi.
Numeric bias-ply sizes are often more familiar to present-day restorers than the older diameter-by-section format, so 550-19 can be an easier replacement path when it matches the wheel and the vehicle's intended presentation. The whitewall and blackwall choice changes the visual character of the car much more than the fitment. If your 6-Standard is being judged, confirm the preferred sidewall treatment with the event or marque community before finalizing that detail.
Buying the Right Tire
Should I choose the 29X5.50 or the 550-19 for my 1930 Dodge?
For a 1930 Dodge 6-Standard, the choice between 29X5.50 and 550-19 is mainly a matter of size convention and presentation, since both are bias-ply formats tied to that model rather than a bias-versus-radial decision. The antique 29X5.50 marking follows the earlier diameter-by-section style, while 550-19 uses the later numeric bias-ply format on a 19-inch wheel. The same kind of decision applies on the other 1930 Dodge models as well: DC owners compare 28X5.50 with 550-18, and DD owners compare 29X5.00 with 500-19.
If your goal is an early-1930s restoration look, the antique-style sidewall marking may be the stronger fit for the car's era. If you want to work within the currently listed product selection for a numeric size, the numeric option is often the easier path because that is where the visible brand and sidewall choices appear. Confirm what is already on the car and whether you are prioritizing historical presentation or a straightforward replacement format.
What sidewall styles are available for 1930 Dodge tires?
1930 Dodge tire sidewall styles vary by size. In 550-19 for the 6-Standard, BFGoodrich offers both Blackwall and Wide Whitewall versions. In 550-18 for the DC, the current selection includes Blackwall, Wide Whitewall, and Double-Whitewall choices from Excelsior, Firestone, and BFGoodrich. In 500-19 for the DD, the listed choices are Blackwall only. That means the look of the finished car depends partly on which Dodge model you own and partly on which size family it uses.
For an early-1930s American car, sidewall appearance has a real effect on authenticity and character. Blackwalls generally suit a simpler, more understated presentation, while whitewalls bring a dressier period look that many restorers prefer on formal passenger cars. Because the available sidewall treatments change by size, choose the correct model and size first, then narrow the visual style from there rather than starting with appearance alone.
What brands make tires for 1930 Dodge vehicles?
Three brands appear in the current 1930 Dodge tire range: BFGoodrich, Firestone, and Excelsior. BFGoodrich is listed in 550-19 and 550-18, Firestone appears in 550-18 and 500-19, and Excelsior appears in 550-18 and 500-19. All of the listed products are bias-ply, but they do not all appear in every 1930 Dodge size. Brand choice is therefore tied directly to the exact model and size you need.
That matters because a 6-Standard owner looking at 550-19 will see a narrower brand range than a DC owner shopping 550-18. A DD owner in 500-19 also has a different mix, including a more specialized Firestone Dirt Track offering. It is smart to decide on the correct size first, then compare brands within that size for appearance, load figure, and rim-width compatibility rather than assuming every brand covers every 1930 Dodge fitment.
Fitting & Setup
What rim width do 1930 Dodge tires require?
Rim-width guidance for 1930 Dodge tires depends on the exact size. In 550-19, the listed fitment range is 2.50 to 3.00 inches. In 550-18, current products reference 3.00, 3.25, and 4.00-inch rims depending on the tire. In 500-19, one product references a 4.00-inch rim and another lists a 4.00 to 5.00-inch range. Those figures should be treated size by size rather than generalized across the whole 1930 Dodge lineup.
Before mounting a new set, measure the actual wheel or confirm the wheel specification from the car's restoration records. A 1930 Dodge that has had wheels swapped over the decades may no longer reflect its original setup, especially if it was modified for touring or hobby use long ago. Matching the tire's approved rim width to the actual wheel is one of the simplest ways to avoid avoidable fitment and appearance problems.
Can the original 1930 Dodge wheels be used with both tire sizes for each model?
Within each individual 1930 Dodge model family, the paired antique and numeric sizes share the same basic wheel diameter. The 6-Standard's 29X5.50 and 550-19 both point to a 19-inch fitment path, the DC's 28X5.50 and 550-18 point to an 18-inch path, and the DD's 29X5.00 and 500-19 point to a 19-inch path. That means the original wheel diameter can often support either style of period bias-ply sizing notation for the same model.
Wheel diameter alone is not the full answer, though, because the actual wheel also needs to suit the tire's approved rim-width range. If your Dodge still has original wheels, inspect them carefully for age, damage, and previous repairs before mounting new tires. If the car has replacement wheels from an older restoration, verify them just as carefully rather than assuming they match original dimensions.
Maintenance, Storage & Longevity
How should I store a 1930 Dodge when the tires are fitted?
A stored 1930 Dodge should be kept in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber. Bias-ply tires benefit from stable inflation pressure during storage and from occasional movement so the same part of the tread is not supporting the car for months at a time. On a long-term display or winter layup, many owners also reduce load on the tires with stands placed correctly under the chassis or suspension, while keeping the tires lightly contacting the floor if preferred by the restorer.
That routine helps preserve sidewall condition and reduces the tendency of an older-style bias-ply casing to develop temporary flat-spotting after long static periods. If the car is stored on bare concrete, use a barrier under the tires and keep the storage area clean and dry. A brief inspection before rolling the car back into service is always worthwhile, even if the tread still looks nearly new.
How long do tires on a 1930 Dodge typically last?
Tires on a 1930 Dodge usually age out before they wear out. On a collector car, five to seven years is a sensible point for closer evaluation, and around ten years is the age when replacement deserves serious consideration regardless of tread depth. The date code on the tire is a better guide than mileage because many vintage Dodges are driven infrequently. Heat, sunlight, storage conditions, and inflation habits all influence lifespan just as much as road use.
That is especially true on a pre-war style car where the tire may see long periods of inactivity between short outings. Even a handsome-looking tire can be past its comfortable service window if the rubber has hardened or the sidewalls have begun to craze. Owners who tour regularly should make age checks part of seasonal maintenance rather than waiting for visible tread wear as the replacement signal.
How often should tires on a 1930 Dodge be inspected?
Tires on a 1930 Dodge should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, tread separation, lodged debris, irregular wear, and any loss of pressure between drives. On an older bias-ply setup, it is also wise to pay attention to how the car feels for the first few miles after storage, because flat spotting or a newly developing casing issue can show up quickly once the car is moving.
A quick visual check is good, but a hands-on inspection is better on a car of this age. Include the spare in the routine, since a spare that has sat untouched for decades may not be usable even if it still holds air. Make inspection part of your pre-drive ritual along with fluid, brake, and lighting checks, especially before touring beyond local roads.
Restoration & Authenticity
What tires were originally fitted to the 1930 Dodge 6-Standard?
A 1930 Dodge 6-Standard would have originally been a bias-ply car, because radial passenger-car fitments were not part of normal American production practice in that era. Within the 1930 Dodge range, the 6-Standard is associated with 29X5.50 and 550-19, both of which are bias-ply size conventions tied specifically to that model. The antique-style marking reflects earlier tire nomenclature, while the numeric style reflects the period's evolving replacement language. Original-equipment brand choice can vary by market, dealer, and the car's service life, so the safer authenticity anchor is correct size, construction, and sidewall character.
For a factory-minded restoration, start with the exact model and verify what size notation best matches the car's intended presentation. Surviving literature, marque clubs, and period photos can help decide whether an antique size marking or a numeric replacement style better suits your restoration goal. That extra research is worthwhile because a 1930 Dodge can look broadly correct on several bias-ply options, yet still differ in fine points that matter to dedicated judges and marque enthusiasts.
Does correct tire fitment matter for showing a 1930 Dodge?
Correct tire fitment absolutely matters when showing a 1930 Dodge, especially in classes that reward factory-style authenticity. Judges and knowledgeable enthusiasts tend to notice whether the size family matches the model, whether the construction is appropriate to the era, and whether the sidewall treatment suits the car's period presentation. A DC wearing the wrong wheel-diameter tire, or a 6-Standard wearing a style that clashes with the restoration's historical intent, can stand out even to non-specialists.
The exact standard depends on the event. Some local shows are satisfied with a tasteful period-looking bias-ply in the correct general size, while stricter concours settings may expect closer attention to sidewall style and size notation. Before final judging, compare your tire choice with period references and consult a Dodge marque group or the event's rulebook so the tire finish matches the rest of the restoration's level of accuracy.
What is the difference between Firestone and BFGoodrich 550-18 tires for a 1930 Dodge?
For a 1930 Dodge DC in 550-18, Firestone and BFGoodrich both offer bias-ply options, but the listed details differ. Firestone appears in Blackwall and Double-Whitewall form with a listed max load of 1125 pounds at 32 psi and a 3.25-inch rim reference. BFGoodrich appears as a Wide Whitewall with a listed max load of 1000 pounds at 32 psi and a 3.00-inch rim reference. The sidewall presentation is different as well, which can matter as much as the numbers on a show-oriented pre-war Dodge.
That comparison makes the decision less about one brand being universally preferable and more about matching the tire to the wheel and the restoration's visual goal. If your wheel setup aligns better with a 3.00-inch specification and you want a wide whitewall look, the BFGoodrich path may suit the car. If your wheel and presentation point toward Firestone's dimensions or its double-whitewall styling, that option may be the stronger fit.
Safety & Road Use
Are 1930 Dodge tires safe for highway driving?
1930 Dodge tires can be suitable for road use when they are the correct size for the model, are in sound condition, and are driven within the limits of their bias-ply design and the car itself. The listed 1930 Dodge products here do not include explicit speed-rating letters, so the emphasis belongs on proper condition, inflation, and realistic use rather than on a modern speed-category comparison. On a car from 1930, the vehicle's brakes, steering, suspension, wheel condition, and overall mechanical health are usually the more important limiting factors at ordinary touring speeds.
A well-sorted 1930 Dodge used responsibly is a different proposition from a neglected one that simply happens to have fresh-looking rubber. Bias-ply tires also feel different from modern radials, with more sensitivity to road crown and more vintage steering response, so the driver should expect period behavior. If the car is new to you, build confidence gradually on shorter drives before committing to longer highway mileage.
What inflation pressure should I use for 1930 Dodge tires?
Inflation pressure on 1930 Dodge tires should be chosen by the exact tire size and the specific tire's rated information, then checked against period vehicle guidance where available. Among the listed products, 550-19 appears with 1040 pounds at 32 psi, 550-18 appears with load figures of 1000 pounds at 32 psi and 1125 pounds at 32 psi depending on the product, and 500-19 appears with 895 pounds at 32 psi on the listed Firestone tire. Those figures are product ratings, not a blanket instruction to use the same pressure on every 1930 Dodge tire.
The best approach is to start with the original owner's manual or marque guidance for the vehicle's intended operating pressure, then confirm the tire manufacturer's limits for the exact reproduction tire you are using. Do not transfer one size's pressure habit to another size simply because the cars are from the same year. A pressure that suits a 550-18 on a DC may not be the right working pressure for a 500-19 on a DD.
What should I check before taking a 1930 Dodge on a longer drive?
Before a longer drive in a 1930 Dodge, inspect each tire for cracking, cuts, bulges, exposed cords, uneven wear, and stable inflation, then check the spare with the same care. Pay close attention to valve stems, bead seating, and wheel condition, since age-related issues can arise in the wheel and hardware as much as in the tire itself. If the car has sat for weeks or months, roll it slowly at first and note any persistent thump, pull, or vibration that does not clear as the tires warm up.
Tires are only one part of the picture on a car from 1930, so include brakes, wheel bearings, steering play, fluid levels, lights, and basic roadside tools in the pre-trip routine. A modest local shakedown drive before a major outing can reveal issues while you are still close to home. That habit is often the difference between a pleasant vintage tour and a preventable roadside interruption.
