The 1926 Chrysler 4 Cyl. comes from Chrysler’s early years, when the brand was building a reputation for advanced engineering and a more refined driving character than many contemporaries. For owners restoring or maintaining one today, tire selection is part mechanical necessity and part visual decision, because this car is associated with two period bias-ply sizes: 30X5.25 and 5.25-20. Those sizes represent two different vintage sizing conventions rather than a modern one-size-fits-all replacement path. The key is confirming which wheel and tire setup is actually on the car, then choosing a period-style tire that suits restoration goals and careful road use.
Which Tire Size Is Right for The 1926 Chrysler 4 Cyl.
The 1926 Chrysler 4 Cyl. uses two primary tire sizes, and the first step is confirming which wheel and tire setup the car has before choosing a replacement. Both fitments are bias-ply, but they use different sizing conventions and different rim diameters, so the real decision starts with wheel identification and then moves to period-style appearance and proper vintage fitment.
30X5.25 is an antique diameter-by-section size, meaning the first number refers to the tire’s approximate overall diameter and the second identifies its section width. On the 1926 Chrysler 4 Cyl., this is a bias-ply fitment tied to an early vintage sizing system that looks very different from later numeric sizes. Its main relevance is authenticity of presentation and compatibility with the correct wheel setup for that format. This size deserves a careful wheel check before replacement, especially on a car that may have changed wheels or tires during its long service life.
5.25-20 is a numeric bias-ply size in which 5.25 identifies the nominal section width in inches and 20 identifies the rim diameter. For a 1926 Chrysler 4 Cyl., this size represents a more familiar vintage numeric format while still keeping the traditional bias-ply construction expected on a period car. The practical choice here is less about construction type and more about making sure the wheel diameter matches and the tire suits the car’s restoration direction. It is the size to evaluate when the car is equipped with 20-inch wheels rather than the antique 30X5.25 setup.
Fitment is straightforward at the sub-model level, because the covered 1926 Chrysler 4 Cyl. Base is associated with the same two primary tire sizes. What matters most is not trim distinction, but confirming which wheel and tire format the car actually carries before selecting a replacement.

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.
Frequently Asked Questions
Owners of a 1926 Chrysler 4 Cyl. usually need to sort out vintage tire sizing, wheel diameter, period-style appearance, and basic road-use readiness. These answers focus on the practical checks that matter before replacing or driving tires on an early Chrysler.
Tire Size & Fitment
What tire size fits a 1926 Chrysler 4 Cyl.?
The 1926 Chrysler 4 Cyl. is associated with two primary bias-ply tire sizes: 30X5.25 and 5.25-20. Those are both vintage fitments, but they are not simply two ways of writing the same modern-style tire size. They represent different sizing conventions and different rim setups on an early vehicle.
The most important next step is confirming which wheels are actually on the car. Many pre-war and early classic vehicles have had wheels, rims, or tires changed over the decades, so the right replacement depends on matching the existing wheel diameter and the tire format already in use.
What size rim does a 1926 Chrysler 4 Cyl. use?
The 1926 Chrysler 4 Cyl. is associated with two rim diameters through its tire fitments: 5.0 inches with 30X5.25 and 20.0 inches with 5.25-20. That means rim size cannot be assumed from the year and model alone when choosing a replacement tire for this car.
A hands-on wheel inspection matters before ordering vintage tires, especially on an older restoration or a long-stored car. Confirm the actual wheel diameter, look for signs of older conversions or mixed wheel sets, and make sure the tire size being considered matches the wheel rather than relying on appearance alone.
What does 30X5.25 mean on a 1926 Chrysler 4 Cyl.?
30X5.25 is an antique diameter-by-section size. On that format, the first number refers to the tire’s approximate overall diameter, while the second number refers to section width. For a 1926 Chrysler 4 Cyl., it is a period bias-ply fitment and should be understood as an early sizing system rather than a later rim-diameter-first size code.
That distinction matters because a buyer could easily confuse 30X5.25 with a modern or later vintage size if reading the code too quickly. The tire should be matched to the actual wheel setup on the car, and any replacement should be checked carefully for wheel compatibility and overall fit on the vehicle.
Choosing the Right Tire
What should I consider when choosing a tire for a 1926 Chrysler 4 Cyl.?
Start with the actual tire size and wheel diameter on the car, because the 1926 Chrysler 4 Cyl. is associated with both 30X5.25 and 5.25-20 bias-ply fitments. Construction choice is simpler here since both primary fitments are bias-ply, so the main issue is matching the correct vintage sizing system and wheel.
After size confirmation, think about the car’s intended use and restoration direction. A preservation-minded car may call for the tire format that best suits its present wheel setup and period appearance, while a regularly driven collector car still needs the same careful checks for wheel condition, clearance, and general roadworthiness.
How do I choose between 30X5.25 and 5.25-20 tires for a 1926 Chrysler 4 Cyl.?
The choice between 30X5.25 and 5.25-20 is not a matter of preference alone, because each size belongs to a different wheel and sizing convention. 30X5.25 is an antique diameter-by-section tire, while 5.25-20 is a numeric bias-ply size built around a 20-inch rim designation.
The deciding factor is the wheel setup currently on the car. Measure the rim, verify what size is already fitted if the tires are still readable, and inspect for older changes made during restoration or past service. Choosing by appearance alone can lead to ordering the wrong vintage format.
Why does the 1926 Chrysler 4 Cyl. have more than one tire size?
The 1926 Chrysler 4 Cyl. is associated with more than one tire size because vintage vehicles often appear with more than one established fitment pattern over time, especially when different wheel setups are involved. In this case, both 30X5.25 and 5.25-20 are bias-ply sizes, but they belong to different sizing conventions.
That makes confirmation especially important on an early car that may have seen decades of maintenance, restoration, or parts changes. The safest path is to inspect the wheels currently installed and match the replacement tire to the wheel diameter and sizing format rather than assuming every 1926 Chrysler 4 Cyl. is equipped the same way.
Restoration & Appearance
Which tire should I choose for a period-style 1926 Chrysler 4 Cyl.?
A period-style 1926 Chrysler 4 Cyl. should stay with the primary bias-ply sizing convention that matches the wheels currently on the car, whether that is 30X5.25 or 5.25-20. Both sizes suit the car’s vintage character far better than forcing a later-style substitute that changes the visual relationship between tire and wheel.
Restoration goals matter here because wheel setup often determines which tire format looks and fits appropriately. Owners pursuing high-detail authenticity should compare the car against marque references, restoration photos, or period literature, while drivers focused on sympathetic presentation should still preserve the correct vintage size language and wheel match.
Does correct tire fitment matter for a 1926 Chrysler 4 Cyl. restoration?
Correct tire fitment matters on a 1926 Chrysler 4 Cyl. because the tire is a major visual and mechanical part of an early car’s stance. Using the proper bias-ply size format for the wheel setup helps preserve the proportions that make a pre-war era vehicle look right and function as intended.
Fitment also affects practical details beyond appearance. A mismatched vintage tire can create avoidable issues with wheel compatibility, clearance, and overall presentation, even if it seems close at first glance. On a restoration, tire selection should be treated as part of the car’s overall correctness rather than an afterthought.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1926 Chrysler 4 Cyl.?
Yes, modifications can affect tire fitment on a 1926 Chrysler 4 Cyl., especially because this car is already associated with two very different vintage tire formats. Changes to wheels, rims, brake components, suspension parts, or body clearances can alter what size works properly even when the vehicle still appears stock at a glance.
An older restoration should be inspected carefully before new tires are chosen. Look at the actual wheel diameter, confirm that all four wheels match, and check steering and fender clearance through the full range of motion. Early cars often carry decades of accumulated changes that are easy to miss.
What should I inspect before driving a 1926 Chrysler 4 Cyl. on new tires?
Before driving a 1926 Chrysler 4 Cyl. on new tires, inspect the wheels, valve hardware, and overall condition of the mounting surfaces, then verify that the tire size matches the wheel setup on the car. On any collector vehicle, it is also wise to check for looseness, uneven wear patterns, or signs of prior clearance issues.
Road readiness goes beyond the tire itself. Examine steering response at low speed, make sure inflation is appropriate for the tire in use, and recheck the tires after the first few miles for seating, air retention, and any rubbing. A careful initial inspection helps avoid problems on a lightly used antique vehicle.
How should tires on a collector 1926 Chrysler 4 Cyl. be maintained?
Tires on a collector 1926 Chrysler 4 Cyl. should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and air loss, and protected from long periods of heat, sunlight, and ozone exposure. Antique vehicles often accumulate little mileage, so age and storage conditions can matter as much as visible tread wear.
Routine checks are especially important before tours or seasonal use. Roll the car periodically if it sits for long stretches, inspect the sidewalls closely before driving, and pay attention to any vibration or pull that suggests a wheel, tire, or suspension issue. Low annual mileage does not eliminate tire maintenance needs.
