Chrysler 60 Series Tires
Chrysler 60 Series was part of the company’s energetic late-1920s rise, when Chrysler was building modern, higher-performance cars that helped define the upper end of the medium-price American market. Produced in 1927, Chrysler 60 Series sits in an important transition period when the industry was moving from earlier balloon-era sizing conventions toward more modern standardized fitments. Tire selection is not entirely straightforward because one 1927 Chrysler 60 Series can appear with two different size formats, and those formats do not describe the wheel in the same way. The first thing to confirm on any Chrysler 60 Series is whether the car carries the earlier 18-inch fitment or the alternate sizing convention tied to the actual wheel and tire dimensions.
Chrysler 60 Series Tire Size Guide
Chrysler 60 Series uses 2 distinct tire sizes across the 1927 model year. One size appears in antique diameter-by-section form, and in that format the leading number is the tire’s outside diameter rather than the wheel diameter. That makes it especially important to verify the actual rim diameter on the car before choosing a replacement.
28X5.25 is an antique-format size listed for 1927 Chrysler 60 Series applications. The 28 indicates an overall tire diameter of about 28 inches, the 5.25 indicates section width, and the wheel diameter is not contained in the size code itself. Choose this size only after confirming the wheel and original fitment details on the specific Chrysler 60 Series, since antique-format sizing can be confused with later wheel-based sizes.
5.25-18 is a numeric bias-ply size also listed for 1927 Chrysler 60 Series applications. The 5.25 identifies nominal section width in inches and the 18 identifies an 18-inch rim diameter. Choose this size when the car is equipped for the 18-inch fitment, and verify the wheel itself because the same model year is associated with more than one listed size.
Chrysler 60 Series Tires by Year
The year listing breaks Chrysler 60 Series tire fitment down by model year so you can match the car to the correct size before moving on to product selection. In 1927, more than one size is listed, so the specific wheel and configuration need to be checked rather than relying on the model year alone. The leading number in 28X5.25 is the tire’s outside diameter, not the wheel size, while 5.25-18 is built around an 18-inch rim.

Frequently Asked Questions
The FAQ below focuses on the two-size 1927 Chrysler 60 Series fitment, including how to decode the older size formats, how to confirm the correct wheel and tire combination, and how to care for a collector car that sees limited road use.
Size Basics & Fitment
Chrysler 60 Series is listed with two tire sizes for 1927: 28X5.25 and 5.25-18. Those two sizes are not just alternate spellings of the same thing. The 28X5.25 size uses an older diameter-by-section convention, while 5.25-18 is a wheel-diameter-based numeric size built for an 18-inch rim.
The practical step is to identify what is actually on the car before choosing a tire. Check the wheel diameter directly, compare the existing tire markings if they are still readable, and verify against original paperwork or a Chrysler specialist if the car has been restored or modified over the years.
On Chrysler 60 Series, 28X5.25 is an antique-style size designation. The first number, 28, refers to the tire’s approximate overall outside diameter in inches, not the wheel diameter. The second number, 5.25, refers to the tire’s section width.
That distinction matters because a modern buyer may assume the first number identifies the rim, which it does not in this format. When working with a Chrysler 60 Series carrying 28X5.25 markings, inspect the wheel itself and use the actual rim measurement as the deciding fitment check before selecting any replacement tire.
A 1927 Chrysler 60 Series can show 28X5.25 and 5.25-18 because the model year is associated with two different sizing conventions. One is an older overall-diameter format and the other is a numeric bias-ply size tied directly to an 18-inch wheel. They should not be treated as interchangeable without checking the actual car.
That means year alone is not enough to choose a tire for a 1927 Chrysler 60 Series. A restored car may have had wheels changed, and an unrestored car may still carry its original arrangement. Confirm the wheel diameter first, then match the tire size to that wheel rather than selecting by year only.
Chrysler 60 Series uses an 18-inch rim when fitted with the numeric 5.25-18 size. The antique-style 28X5.25 marking does not state the wheel diameter in the size code itself, so the rim cannot be identified from those numbers alone. That is why the two listed sizes need to be handled differently during fitment research.
If the car is wearing 5.25-18 tires, the rim diameter is straightforward to interpret. If it carries 28X5.25 markings, measure the wheel or compare it with trusted period references for the specific car. That extra check helps avoid ordering a tire that matches the old size language but not the actual wheel.
Buying the Right Tire
The most reliable way to confirm tire size on a 1927 Chrysler 60 Series is to start with the wheel itself and the tire markings currently on the car. Chrysler 60 Series is associated with both 28X5.25 and 5.25-18, so the year by itself does not settle the question. You need to know whether the car is set up for the antique-style size convention or the 18-inch numeric fitment.
Measure the wheel diameter, inspect all four tires for readable sidewall markings, and compare those findings with period service literature or a Chrysler marque expert if there is any doubt. That is especially important on older restorations, where replacement wheels or mixed spare-tire fitments can create confusion.
Maintenance & Longevity
A Chrysler 60 Series should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, heaters, and ozone-producing equipment. Tire pressure should be maintained at the appropriate level for the fitted tire type, and the car should not be left sitting for long periods with excessive weight concentrated on one contact patch.
If the Chrysler 60 Series will be parked for an extended time, roll it slightly from time to time or support it in a way that reduces flat-spotting stress on the tires. Clean, dry storage and periodic movement are especially helpful on collector cars that are driven only occasionally.
Tires on a Chrysler 60 Series should be visually inspected before each drive and checked more thoroughly several times during the season, even if the car sees only short trips. Look for cracking, weathering, tread separation, irregular wear, underinflation, and any signs that the tire is shifting on the rim or the valve stem is being stressed.
On a lightly used collector car, deterioration often comes from age and storage conditions rather than mileage. Regular inspections help catch issues before a parade, club event, or road outing, and they are a sensible habit on any Chrysler 60 Series that spends much of its life parked.
A Chrysler 60 Series may need new tires even when the tread still looks deep, because age, drying, internal degradation, and storage history can make an older tire unfit for service. Cracks in the sidewall, vibration, flat spotting that does not recover, exposed cord, or any sign of structural weakness are all strong reasons to retire the tire.
Collector-car owners should treat tire age and condition as seriously as tread depth. If a Chrysler 60 Series has been sitting for years, have the tires inspected closely before road use, since long periods of inactivity can shorten service life even on a car that has traveled very few miles.
Restoration & Authenticity
Chrysler 60 Series is associated here with two period-correct size conventions for 1927: 28X5.25 and 5.25-18. That indicates Chrysler 60 Series fitment can involve more than one legitimate tire specification within the model year. The correct original choice for a particular car depends on how that individual car was equipped.
For restoration work, the best approach is to compare the car against factory literature, surviving original examples, and Chrysler club or marque expertise. Using the right size convention matters because it affects both appearance and wheel compatibility, not just whether the tire can be mounted.
Correct tire fitment can absolutely affect both presentation and judging on a Chrysler 60 Series. Judges and knowledgeable enthusiasts look at overall stance, sidewall appearance, wheel-to-tire proportion, and whether the tire size matches the era and configuration of the car. A visibly incorrect size can alter the car’s proportions as much as an incorrect wheel or trim detail.
For an owner focused on authenticity, tire choice should be part of the restoration plan rather than a last-minute purchase. Matching the Chrysler 60 Series to the proper period size convention helps preserve the car’s historical character and is often appreciated by marque specialists and show judges alike.
Sidewall style on a Chrysler 60 Series restoration should match the era, the intended presentation of the car, and the specific tire line being considered. Late-1920s American cars can look noticeably different depending on whether they wear a plainer service appearance or a more dress-oriented sidewall treatment. The right answer is the one that aligns with the way the particular Chrysler 60 Series was originally equipped or is being authentically restored.
A restorer should compare the car with period photos, sales literature, and marque-club guidance before settling on sidewall appearance. That extra step matters because sidewall style is one of the first visual details people notice, and it has a strong effect on whether a Chrysler 60 Series looks accurately finished.
Safety & Road Use
A Chrysler 60 Series can be driven on public roads when it is fitted with suitable tires in sound condition and the car itself is mechanically prepared for road use. Tire safety depends on proper size selection, correct inflation, wheel condition, and the age and integrity of the tires. On a car from 1927, those factors matter at least as much as tread depth.
Before regular road use, inspect the entire running gear of the Chrysler 60 Series, including wheels, tubes if fitted, brakes, steering, and suspension. A collector car should be driven within the limits of its tire construction and overall mechanical condition rather than treated like a modern sedan.
Before driving a Chrysler 60 Series, check tire pressure, look for visible cracks or bulges, inspect the tread and sidewalls, and make sure the valve stems and wheel hardware appear sound. It is also wise to confirm that all four tires match in size and type, especially on a car where more than one 1927 size convention can appear.
A short pre-drive walkaround can prevent most avoidable tire issues on a collector car. Chrysler 60 Series owners should also pay attention to brake feel, steering response, and any new vibration once the car starts moving, because an old tire problem often shows up first as a change in how the car behaves.
A Chrysler 60 Series should be driven at moderate speeds that respect both the tire construction and the age of the car’s chassis, brakes, and steering system. Even with correctly sized period-style tires, a late-1920s automobile was engineered around a very different margin of control and stopping ability than a modern car. Conservative road speeds are the right approach.
In practice, that means avoiding sustained high-speed running and treating the Chrysler 60 Series as a historic touring car rather than a modern highway machine. Smooth inputs, extra following distance, and realistic expectations about braking and cornering will do more for safety than any single tire choice alone.
