The 1930 Chrysler 66 Series comes from a period when Chrysler was building well-engineered cars for owners who expected refinement, durability, and confident road manners on the highways of the early Depression era. Tire choice on a car like this is closely tied to both appearance and proper vintage fitment, especially because the 66 Series uses bias-ply sizing in 28X5.50 and 550-18 on 18-inch wheels. That keeps the decision centered on traditional construction rather than modern radial conversion. Within that fitment, choices include blackwall, wide whitewall, and double-whitewall presentations across several period-style tire series. The right selection depends on how the car is being restored, displayed, and driven.
Which Tire Size Is Right for The 1930 Chrysler 66 Series
The 1930 Chrysler 66 Series uses two primary tire size designations, and both apply to the 6 Cyl. sub-model in bias-ply construction on 18-inch rims. The key question is not simply which size fits, but which sizing convention matches the car's wheel setup and restoration direction, then which sidewall style and tire series best suit the way the car is presented and used.
A 28X5.50 tire uses an older diameter-by-section format, where the first number refers to the tire's approximate overall diameter and the second number refers to section width in inches. On the 1930 Chrysler 66 Series, this is a bias-ply vintage fitment style that suits the period character of the car and its early wheel-and-tire sizing language. It is best understood as part of a restoration-oriented setup rather than a modern size system. Before choosing this designation, confirm that the wheel and existing tire markings on the car align with this older style of fitment.
A 550-18 tire is a numeric bias-ply size in which the 550 refers to nominal section width, roughly 5.50 inches, and the 18 identifies the rim diameter. For the 1930 Chrysler 66 Series, this is the more familiar vintage replacement format tied directly to an 18-inch wheel. Available choices include Excelsior, Firestone, BFGoodrich, and Michelin offerings, with blackwall, wide whitewall, and double-whitewall sidewall treatments across series such as Comp H, Firestone Classic Bias Ply, Silvertown Classic Bias Ply, and Double Rivet. This size gives the buyer the clearest path for matching appearance, wheel width, and intended presentation.
Fitment is straightforward across the covered 1930 Chrysler 66 Series sub-models because the same two bias-ply size designations are used. Checking the exact sub-model still matters so the wheel setup and the tire markings already on the car can be matched before choosing a replacement.

1930 Chrysler 66 Series 6 Cyl.
The 1930 Chrysler 66 Series 6 Cyl. uses the same pair of bias-ply fitment designations found at the model level, centered on 18-inch wheel fitment. That means the real selection comes down to matching the car's current wheel and tire convention, then choosing the sidewall treatment and tire series that best fit a period-style restoration or touring presentation.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1930 Chrysler 66 Series?
The 1930 Chrysler 66 Series uses two primary bias-ply tire size designations: 28X5.50 and 550-18. The covered 6 Cyl. sub-model uses these same fitments, so the tire decision centers on matching the car's wheel and existing sizing convention rather than sorting through different sub-model-specific sizes.
Those two sizes reflect different vintage naming systems, not a modern front-and-rear stagger or performance option. Checking the tire markings already on the car, confirming the wheel diameter, and making sure the replacement matches the intended restoration appearance will help narrow the choice before moving on to sidewall style, brand, or tire series.
What size rim does a 1930 Chrysler 66 Series use?
The 1930 Chrysler 66 Series uses an 18-inch rim with its 550-18 bias-ply fitment. That 18-inch diameter is the key wheel measurement to verify before selecting a replacement tire, especially on a collector car that may have had wheel changes over time.
Wheel diameter is only part of the picture on an early Chrysler. Rim width should also be checked against the tire being considered, since available 550-18 products are built around different approved rim-width measurements. A quick wheel inspection before ordering helps avoid mismatching a vintage tire to a non-original or altered wheel setup.
Does the 1930 Chrysler 66 Series 6 Cyl. use the same tire size?
Yes. The 1930 Chrysler 66 Series 6 Cyl. uses the same two bias-ply size designations associated with this model: 28X5.50 and 550-18. There is no separate alternate fitment here that changes the basic tire-selection path for that sub-model.
That consistency makes the process simpler, but the car should still be checked carefully because many pre-war vehicles have seen wheel swaps, long-term storage, or mixed old tires over the years. Matching the replacement to the actual wheel diameter and the tire convention already in use remains more important than relying on a visual guess.
Choosing the Right Tire
What should I consider when choosing a 550-18 tire for a 1930 Chrysler 66 Series?
Start with the basics: correct 550-18 size, bias-ply construction, and compatibility with the car's 18-inch wheel. From there, the main choices are sidewall appearance, brand, tire series, and rim-width suitability, since available 550-18 options include blackwall, wide whitewall, and double-whitewall styles.
A car being restored for traditional visual impact may call for a different sidewall treatment than one meant for frequent touring. It also helps to compare approved rim width, weight, and any stated load figure at its listed pressure so the tire suits both the wheel and the way the Chrysler will actually be driven.
What sidewall styles are available for 1930 Chrysler 66 Series tires?
For 550-18 fitment on the 1930 Chrysler 66 Series, available sidewall styles include blackwall, wide whitewall, and double-whitewall. Those choices have a major effect on the car's finished look, especially on a late-1920s to early-1930s vehicle where tire presentation is a visible part of the overall restoration.
A blackwall usually gives a restrained, functional appearance, while whitewall treatments bring more visual emphasis to the wheel area. The best choice depends on the car's trim, restoration goals, and the look being recreated. If exact historical authenticity matters, compare the selected sidewall style against period photos or marque-specific references.
What brands offer tires for the 1930 Chrysler 66 Series?
The 550-18 fitment for the 1930 Chrysler 66 Series is available from Excelsior, Firestone, BFGoodrich, and Michelin. Those brands appear across several vintage tire series, giving buyers more than one path for matching the car's intended appearance and wheel requirements.
Brand choice should be weighed alongside the tire series, sidewall treatment, and wheel compatibility rather than viewed by name alone. One product may better suit a blackwall touring presentation, while another may line up better with a wide whitewall restoration look. Comparing the full specification is more useful than choosing by brand only.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Chrysler 66 Series?
A period-style 1930 Chrysler 66 Series tire choice starts with the correct bias-ply fitment and the proper vintage size convention, then moves to the visual details. In practical terms, 550-18 offers the clearest selection path because it is available in several vintage series and sidewall treatments that suit an early-1930s presentation.
The best match depends on whether the car is being restored with a restrained blackwall look or with more formal whitewall styling. Exact originality can vary by body style, market, and prior restoration decisions, so highly detailed authenticity work is best checked against period literature, marque-club guidance, and surviving reference cars.
How does tire construction affect the appearance of a restored 1930 Chrysler 66 Series?
Bias-ply construction plays a major role in how a restored 1930 Chrysler 66 Series looks. The tire shape, sidewall character, and overall visual presentation align with the era of the car in a way that supports a traditional pre-war stance and complements vintage wheel and body proportions.
Appearance is also shaped by the chosen sidewall treatment, since blackwall, wide whitewall, and double-whitewall options can change the car's personality without changing the underlying fitment. For a restoration-focused car, keeping the proper construction and size format usually matters just as much as choosing the right paint, trim, or wheel finish.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Chrysler 66 Series?
Yes. Even though the 1930 Chrysler 66 Series uses established vintage bias-ply fitments, wheel changes, brake updates, suspension work, or body alterations can affect what actually clears the car. That matters especially on older vehicles that may have been updated long after leaving their original service life.
A modified Chrysler should be checked for actual wheel diameter, wheel width, and space around the fenders and steering components before replacing tires. Small differences in wheel setup can matter on pre-war cars, so measuring the current hardware is more dependable than assuming the car still matches a fully original configuration.
What should I inspect before driving a 1930 Chrysler 66 Series on new tires?
Before driving a 1930 Chrysler 66 Series on new tires, inspect the wheels for damage, verify the rims are appropriate for the selected tire, and make sure the tires are seated and inflated correctly. It is also worth checking valve stems, lug security, and whether the car rolls and steers cleanly without rubbing.
A collector car benefits from a broader pre-drive inspection as well. Look at steering and suspension wear, brake condition, wheel-bearing play, and any signs that the car has been sitting for long periods. A short local test drive followed by another visual check can catch clearance or pressure issues before a longer outing.
How should 550-18 tires on a collector 1930 Chrysler 66 Series be maintained?
550-18 tires on a collector 1930 Chrysler 66 Series should be kept at the proper operating pressure for the tire being used and inspected regularly for cracking, cuts, bulges, uneven wear, or slow air loss. Vintage-use cars often age their tires through time and storage as much as through mileage.
Good storage habits make a real difference. Keeping the Chrysler out of prolonged sun, moisture, and ozone sources helps protect the sidewalls, and moving the car periodically can reduce stress from long static parking. Routine inspection matters even more on a lightly driven pre-war car than it does on a regularly used modern vehicle.
