1929 Vehicle Tire Fitment Guide

30X5.50 appears on the 1929 Buick 116 Standard along with the Elcar 95 Series and Elcar 96 Series. This is a bias-ply inch-style balloon size that sits between the smaller five-inch and larger six-inch family of period fitments, making it useful for medium-sized late-1920s cars. Because the application spread is limited, it is less of a universal 1929 size and more of a targeted fitment. Owners looking for the right stance and visual balance on these models should verify wheel dimensions and any prior changes, especially if the car has been restored over many decades.

Rim Diameter: 20 in  ·  Sidewalls: Wide Whitewall, Blackwall

550-20 is the dash-format companion fitment for the 1929 Buick 116 Standard and Elcar 95 Series and 96 Series. Available BFGoodrich products include both blackwall and wide whitewall versions, each built as bias-ply tires for 20-inch rims and listed for 3-inch wheel widths. That makes this size attractive for restorers who want a clear sidewall-style choice without leaving the period bias-ply category. Since wheel diameter is explicit in the size, it is easier to distinguish from nearby 18- and 19-inch fitments, but exact application still matters before purchase.

32X6.50 is used on the 1929 Buick 121 Master and Buick 129 Master, placing it among the larger inch-style fitments found on upper-series cars for the year. This bias-ply designation reflects the substantial proportions expected on more upscale late-1920s Buicks. Because it is limited to these related Buick models, shoppers should think of it as a model-family fitment rather than a broadly shared 1929 size. It is also a reminder that even within one make, moving from Standard to Master lines can change tire requirements significantly.

Rim Diameter: 20 in  ·  Sidewalls: Wide Whitewall, Blackwall

650-20 fits the 1929 Buick 121 Master, Buick 129 Master, and Elcar 120 Series and offers one of the more varied product groups for the year. Choices include Firestone blackwall and wide whitewall passenger-style bias-ply tires, plus Denman and Deka classic truck-oriented blackwall options carrying a Military & Truck attribute. Rim diameter is 20 inches, and Firestone listings include a broad 3.00 to 5.00-inch rim width range plus a stated 2120-pound load capacity at 60 psi. That mix makes it especially important to select by intended use, appearance, and wheel specification.

Reserved here for the 1929 Cadillac 8 Cyl., 32X7.00 is one of the largest passenger-car inch-style fitments in this year grouping. Its bias-ply construction suits the scale and character expected of a premium late-1920s luxury car, where tire diameter and section width contribute heavily to stance and proportion. Because this size is not shared broadly, Cadillac owners should be careful not to substitute based on similar-looking dimensions from other high-end makes. Proper wheel and body clearance remain important, particularly on restored cars with uncertain wheel history.

Rim Diameter: 20 in  ·  Sidewalls: Double-Whitewall, Wide Whitewall, Blackwall

700-20 is used on the 1929 Cadillac 8 Cyl., Cunningham 8, Packard 633 Series, Packard 645 Series, and Stearns-Knight H8-90. This is a large bias-ply 20-inch fitment with notable product diversity, including Firestone Balloon and BFGoodrich options in blackwall, wide whitewall, and double-whitewall styles. Rim width guidance varies by product, with examples spanning 3.75 to 4.00 inches and 5.00 to 5.50 inches, so not every tire in the size should be assumed identical in wheel compatibility. It is a major luxury-car fitment where load, wheel width, and presentation all matter.

29X5.00 is a common 1929 bias-ply size used across Chandler 65 Series, Dodge 6-Standard, Durant 60 Series, Durant 66 Series, Graham 12 Series, Pontiac 6 Cyl., and Whippet 98A. Its broad use shows how many medium-priced cars of the period clustered around similar balloon-tire dimensions. Because the size appears on several makes, it is useful for year-level research, but it should still be matched to the exact model and wheel setup. This fitment represents the practical middle of the 1929 market rather than the smallest economy applications or the largest luxury-car sizes.

Rim Diameter: 19 in  ·  Sidewalls: Blackwall

500-19 is one of the most widely shared bias-ply sizes in the 1929 field, appearing on Chandler 65 Series, De Soto 6, Dodge 6-Standard, Durant 60 Series, Durant 66 Series, Elcar 75 Series, Graham 12 Series, Pontiac 6 Cyl., and Whippet 98A. Available products include an Excelsior Comp H blackwall and a Firestone Dirt Track ribbed-front blackwall tire, showing that product character within the size can differ meaningfully. The 19-inch rim diameter is clear, but users should select with care because a racing-oriented ribbed front tire serves a different purpose than a general vintage replacement.

Used across a dozen makes, 29X5.50 is one of the most widely shared 1929 bias-ply fitments, covering cars such as the Chandler 75 Series, Studebaker Commander, Studebaker Dictator, Oakland AA, and Willys-Knight 70B Series. That broad reach makes it a key size for owners researching mainstream late-1920s passenger cars. Even so, shared nominal size does not eliminate the need to verify exact wheel and vehicle configuration. On collector cars, this fitment often appeals to shoppers who want an appropriate period scale without stepping into the larger dimensions used on senior or luxury models.

Rim Diameter: 19 in  ·  Sidewalls: Blackwall, Wide Whitewall

550-19 mirrors the broad usage of 29X5.50 and fits a large group of 1929 cars from Chandler, Durant, Gardner, Graham, Hupmobile, Marmon, Moon, Oakland, Peerless, Studebaker, and Willys-Knight. Product offerings include BFGoodrich blackwall and wide whitewall bias-ply tires, each listed for 19-inch rims with a 2.50 to 3.00-inch rim width range and a 1040-pound load capacity at 32 psi. For owners comparing period appearance, this size gives a straightforward choice between understated blackwall and more decorative whitewall styling. It is a strong example of shared fitment across many mid-range marques.

30X5.77 is a specialized late-1920s bias-ply fitment used on the Chandler 85 Series, Chandler Big, Elcar 120 Series, Packard 626 Series, Stearns-Knight M6-80, Stearns-Knight N6-80, and Studebaker President. It stands out because it sits outside the more common round-number sizes and tends to appear on larger, more distinctive model lines. Since unusual period dimensions can easily be confused with nearby alternatives, careful confirmation is important before purchase. This is the kind of size where owners often balance faithful period proportions with the practical reality of which currently offered tires are available for the application.

30x5 is another 1929 bias-ply fitment associated with Chandler 85 Series, Chandler Big, Packard 626 Series, Stearns-Knight M6-80, Stearns-Knight N6-80, and Studebaker President. Although visually similar to other early size markings, it should be treated as its own application reference rather than merged casually with another designation. This size appears on substantial cars where maintaining correct overall look can be just as important as basic rolling fit. Because period notation can vary in old references and on surviving vehicles, owners should compare the tire marking, wheel setup, and exact model before selecting a replacement.

29X4.50 is used here only on the 1929 Chevrolet 6 Cyl., making it one of the more model-specific fitments for the year. As a bias-ply inch-style balloon size, it reflects the lighter end of the late-1920s passenger-car market. A single-make application like this is helpful for Chevrolet-focused restoration research, but it also means cross-shopping by appearance alone can be risky. Smaller period tires can be especially sensitive to wheel condition and inflation, so exact sizing and a careful look at the vehicle’s current setup are worthwhile before installation.

Rim Diameter: 20 in  ·  Sidewalls: All White

450-20 is the companion dash-format bias-ply fitment for the 1929 Chevrolet 6 Cyl. and is offered here in a Universal Vintage Tire All White version for a 20-inch rim. That all-white sidewall treatment gives this size a distinct visual option compared with many other 1929 fitments that are available mainly in blackwall or wide whitewall form. Because the product listing does not include a rim width, wheel confirmation should be done directly from the vehicle and wheel assembly. It is a very targeted fitment rather than one shared widely across the year.

30X6.75 appears on the 1929 Chrysler Imperial and Kissel 126, placing it among the larger and more prestigious bias-ply fitments used that year. Its limited but upscale application suggests a tire dimension chosen for substantial cars with more imposing proportions than the average six-cylinder sedan. Because it is shared by only two makes and sits near other large balloon sizes, accurate identification is especially important. For restoration-minded owners, this fitment is less about broad interchange and more about preserving the correct scale and character of a senior late-1920s automobile.

Rim Diameter: 18 in  ·  Sidewalls: Double-Whitewall, Blackwall, Wide Whitewall

700-18 is used on the 1929 Chrysler Imperial and Kissel 126 and has one of the richer product selections among 18-inch 1929 fitments. Firestone offers this bias-ply size in Balloon and Classic Bias Ply series, with blackwall, wide whitewall, and double-whitewall versions. Listed rim width guidance of 3.75 to 4.00 inches and a load rating of 1520 pounds at 36 psi on several products make it easier to evaluate wheel and use considerations. This is a premium-size application where sidewall presentation can materially affect the finished look of the car.

32X6.75 fits the 1929 Cunningham 8, Packard 633 Series, Packard 645 Series, and Stearns-Knight H8-90. This bias-ply inch-style size belongs to the upper tier of late-1920s passenger-car fitments and is associated with large, prestigious automobiles. Because these vehicles share broad luxury-car proportions, the size is useful for cross-reference work within that class, but it remains a distinct fitment rather than a generic substitute for all senior cars. Owners should confirm the actual wheel and tire marking on the vehicle, especially where older restorations may have mixed period and later references.

31X6.00 is a common bias-ply fitment shared by 11 makes, including Dodge 6-Sen., Duesenberg 8 Cyl., Franklin 130 Series, Hudson Super 6, Stutz L6, Stutz L8, and Windsor 85 Series. Its wide use makes it one of the key anchor sizes for 1929 vehicle tire research, especially on larger sixes and eights that stop short of the biggest luxury dimensions. Even with broad coverage, it should not be treated as universal. Cars in this range can differ in wheel design, fender clearance, and restoration history, all of which are worth checking before final selection.

Rim Diameter: 19 in  ·  Sidewalls: Wide Whitewall

600-19 serves the same broad group represented by 31X6.00 and is one of the most important 19-inch bias-ply fitments for 1929 cars. The currently listed product is a Lester Classic Bias Ply wide whitewall, giving this size a distinctly restoration-oriented visual option. Because only one listed product style appears in this fitment, shoppers may focus more on vehicle confirmation, wheel condition, and desired appearance than on comparing multiple brands. It is a useful size for substantial late-1920s cars that need a recognizable balloon-tire profile on a 19-inch rim.

28X4.75 is used on the 1929 Durant 4-40, Plymouth 4 Cyl., and Whippet 96A. This bias-ply inch-style size sits toward the smaller end of the 1929 passenger-car range and suits lighter four-cylinder vehicles. Because it is shared by a compact group of makes, it gives these cars some common ground without becoming a broad all-year standard. In practical terms, owners should pay attention to preserving the proper smaller-scale stance and not simply chase a more common nearby size. On vehicles of this class, modest dimensional changes can noticeably alter appearance and clearance.

Rim Diameter: 19 in  ·  Sidewalls: Blackwall, Wide Whitewall

475-19 is the dash-format companion size for the 1929 Durant 4-40, Plymouth 4 Cyl., and Whippet 96A. Goodyear Deluxe All-Weather products are offered in both blackwall and wide whitewall styles, each as bias-ply tires for 19-inch rims with a listed 3-inch rim width and 900-pound load capacity at 32 psi. That makes this size one of the clearer examples where product specifications directly support fitment research. For smaller late-1920s cars, it offers a practical balance between a period-looking tread and a visible sidewall-style choice.

29X6.00 appears only on the 1929 Elcar 75 Series, making it a very specific bias-ply fitment within the year. Although its section width suggests a substantial tire, the size itself should be followed exactly rather than compared loosely with more common 19-inch or 18-inch alternatives. Single-application sizes like this are especially important for restorers trying to maintain correct vehicle proportions. Since cross-make overlap is absent, owners should verify the exact model designation and wheel setup before ordering instead of assuming interchangeability based on similar numerical markings.

29X4.75 is tied specifically to the 1929 Erskine 52 Series and represents a lighter bias-ply balloon-car fitment. It belongs to the smaller end of the year’s size range, where differences of a quarter-inch or a change in wheel diameter can be significant. Because it appears on only one make and model line here, there is little reason to treat it as a general substitute size. For Erskine owners, careful size confirmation is the main priority, particularly on cars that may have accumulated non-original wheels or mixed tire references over time.

4.75-20 is the dash-format fitment for the 1929 Erskine 52 Series and identifies a bias-ply tire built around a 20-inch rim. It occupies the smaller-to-mid range of 1929 applications and is best understood as a direct model-specific requirement rather than a broad family size. Since no product details are listed here for wheel width or styling, the most useful approach is to verify the car’s exact wheel and compare the marked tire size carefully. For compact late-1920s cars, exact rim diameter remains one of the most important fitment checkpoints.

29X4.95 is used only on the 1929 Essex Super 6 and is a good example of how late-1920s sizing can include less common dimensions between the more familiar 4.75 and 5.00 families. This bias-ply application should be handled as a distinct period fitment, not rounded casually to a nearby size. On an Essex Super 6, maintaining the right proportion and wheel relationship matters for both appearance and proper installation. Since unusual sizes can be easy to misread in old literature or on aging sidewalls, direct verification is especially worthwhile.

5.00-20 is the bias-ply dash-format fitment associated with the 1929 Essex Super 6. The size clearly identifies a 20-inch wheel diameter, which helps separate it from 19-inch dimensions that may appear numerically close. Even though the section width sounds similar to other period applications, this should still be matched to the exact Essex model and wheel setup rather than treated as a broad 1929 standard. For owners of moderately sized late-1920s cars, keeping the wheel diameter and overall tire scale correct is often just as important as choosing the right sidewall appearance.

30X4.50 is the inch-style bias-ply fitment for the 1929 Ford A Series and is one of the most recognizable sizes tied to a single model family from this period. It reflects the leaner, practical end of the 1929 market and is distinct from the larger balloon sizes used on more expensive six- and eight-cylinder cars. Because the Ford application is so model-specific, it should be selected by exact size and wheel compatibility rather than by general year. For many restorers, preserving the proper proportions of a Model A-era fitment is a central goal.

Rim Diameter: 21 in  ·  Sidewalls: Wide Whitewall, Blackwall

450-21 fits the 1929 Ford A Series and is offered in Goodyear All-Weather Balloon form in both blackwall and wide whitewall styles. These bias-ply products are listed for 21-inch rims with a 2.75-inch rim width and an 855-pound load capacity at 32 psi. That combination makes this one of the more clearly specified 1929 sizes for product comparison. Ford owners often focus heavily on getting the visual profile right, and the choice between blackwall and whitewall can have a big effect on how a restored A Series presents.

31X6.20 is a substantial bias-ply fitment shared by Franklin 135 Series, Franklin 137 Series, Graham 27, Graham 37, La Salle 8 Cyl., Peerless 125 Series, Pierce Arrow 125 Series, Pierce Arrow 126 Series, Studebaker President, and Windsor 92 Series. This places it in a higher and heavier class than many of the common five-inch section sizes used elsewhere in 1929. Because it spans several premium and upper-mid-level cars, the size is useful for comparison shopping, but exact application still matters. It is best viewed as a senior 19-inch balloon fitment with period-preserving importance.

Rim Diameter: 19 in  ·  Sidewalls: Blackwall, Wide Whitewall

650-19 covers the same upscale group as 31X6.20 and offers a healthy range of bias-ply product styles. Firestone and Lester options are available, including blackwall and wide whitewall versions, and Firestone Balloon listings include a 3.25 to 3.50-inch rim width reference plus a 1430-pound load capacity at 36 psi on the whitewall version. For owners of 1929 Franklin, La Salle, Pierce Arrow, Studebaker President, and similar cars, this size blends broad application coverage with meaningful product choice. Sidewall appearance can strongly shape the finished restoration look in this fitment.

30X6.20 is used on the 1929 Gardner 130 Series, Hudson Super 6, Locomobile 86, and Reo Flying Cloud. This bias-ply inch-style size sits in a useful middle-upper range, larger than the common mid-market sizes yet not as oversized as the biggest luxury-car applications. Its shared use across four makes makes it relevant for cross-reference work, especially on larger touring and sedan models of the period. Because this is one of several close-looking six-inch-family dimensions in 1929, exact size confirmation helps avoid confusion when ordering or comparing old tire markings.

33X6.75 is the largest inch-style fitment listed here and is tied specifically to the 1929 Lincoln 8 Cyl. This bias-ply size belongs to the uppermost end of the year’s luxury-car spectrum, where overall diameter and presence are central to the vehicle’s stance. A fitment this large should be approached carefully, with close attention to exact wheel and body clearance rather than comparison to smaller 700-series alternatives. For Lincoln restorations, maintaining the proper visual scale is likely to be just as important as securing a nominally similar tire dimension.

Rim Diameter: 21 in  ·  Sidewalls: Blackwall, Wide Whitewall, Double-Whitewall

700-21 appears only on the 1929 Lincoln 8 Cyl. and carries one of the more interesting product selections in the year. Firestone Balloon choices include blackwall, wide whitewall, and double-whitewall styles, while Michelin offers a Double Rivet blackwall alternative. Rim width references differ by product, with Firestone listings at 3.75 to 4.00 inches and the Michelin listing at 3.00 to 3.75 inches, so wheel specification should be reviewed closely. This is a senior 21-inch bias-ply fitment where brand, sidewall presentation, and wheel compatibility all deserve attention.

29X5.25 is a bias-ply size shared by the 1929 Marmon 68 Series, Peerless 61Series, and Roosevelt 8 Cyl. It sits between the more common 5.00 and 5.50 family sizes and reflects the nuanced fitment differences found across late-1920s marques. Because it is neither rarest nor most widespread, it serves a narrow but distinct slice of the 1929 market. Owners should avoid assuming that nearby dimensions are interchangeable, especially when trying to preserve proper body-to-tire proportion on collector vehicles where a half-step change can alter stance noticeably.

5.25-19 fits the 1929 Marmon 68 Series, Peerless 61Series, and Roosevelt 8 Cyl. and translates that same moderate-size grouping into a 19-inch dash-format bias-ply application. The currently listed vehicles place it in a narrower niche than 500-19 or 550-19, which were used much more broadly. That makes exact model identification especially useful when sorting among several period-correct-looking choices. With a mid-range section width on a 19-inch wheel, this size can be important for keeping a refined late-1920s car from appearing either under-tired or overly bulky.

28X5.25 is used on the 1929 Marquette 6 Cyl. and Oldsmobile 6F. This is a bias-ply inch-style fitment for a compact group of General Motors-era cars that sit below the larger 29- and 31-inch applications in the same year. Because the size is shared by only two models, it offers some cross-reference value without becoming a general 1929 standard. Owners of these cars should focus on exact size confirmation and proper wheel pairing, especially if the vehicle’s service history includes long-term storage, replacement wheels, or incomplete restoration records.

5.25-18 is the dash-format bias-ply counterpart for the 1929 Marquette 6 Cyl. and Oldsmobile 6F. The 18-inch rim diameter makes it distinct from nearby 19- and 20-inch applications, which helps narrow fitment quickly once the model is confirmed. Although it is a relatively focused size grouping, it still highlights how 1929 tire fitment varied noticeably even among similarly positioned cars. On a restored Marquette or Oldsmobile, keeping the wheel diameter, tire scale, and sidewall profile in harmony is important for both fit and the car’s overall period character.
