The 1926 Dodge 4 Cyl. comes from a period when American motorists still expected sturdy, practical transportation on rougher roads and mixed driving conditions. That makes tire choice especially important, because the right fitment affects not only appearance but also how authentically the car sits and drives. This Dodge uses bias-ply tire fitments, with 31X5.25 and 525-21 both associated with the model. Available choices include traditional blackwall styling as well as a wide whitewall treatment in 525-21. For a restoration-minded owner, the key is confirming which wheel setup is actually on the car before choosing a tire style that matches its intended presentation and road use.
Which Tire Size Is Right for The 1926 Dodge 4 Cyl.
The 1926 Dodge 4 Cyl. is associated with two primary tire sizes, and the first step is confirming which wheel setup is on the car. These fitments differ by sizing system and rim diameter, so the decision is not just about appearance but also about matching the tire to the actual wheel before comparing available bias-ply options.
A 31X5.25 size uses an early diameter-by-section format, where the first number refers to the tire's approximate overall diameter and the second refers to its nominal section width. This is a bias-ply fitment suited to very early wheel and tire conventions, and on this Dodge it needs to be matched carefully to the wheel actually fitted to the car. Its appeal is largely restoration-oriented, since buyers of antique sizes are often trying to preserve a proper prewar stance and visual character. Choosing this size starts with verifying the wheel dimensions already on the vehicle rather than assuming interchangeability with later numeric sizes.
A 525-21 tire uses the vintage numeric bias-ply system, with 5.25 indicating nominal section width and 21 identifying the rim diameter in inches. This is a traditional bias-ply fitment for the 1926 Dodge 4 Cyl. and it offers the clearest range of product choices among the available sizes. Firestone and Excelsior options are available, including Firestone Classic Bias Ply and Comp H series tires, along with blackwall and wide whitewall sidewall treatments. This size is the practical choice to evaluate when the car is on 21-inch wheels and the goal is balancing correct fitment with the desired period-style look.
Fitment is straightforward here because the covered sub-model shares the same two tire sizes already associated with the 1926 Dodge 4 Cyl. Checking the exact wheel setup still matters, since the two sizes use different sizing systems and different rim diameters.

1926 Dodge 4 Cyl. Base
The 1926 Dodge 4 Cyl. Base is associated with both 31X5.25 and 525-21 bias-ply fitments rather than a single universal wheel and tire combination. Tire selection depends on confirming which wheel diameter is on the car, then choosing the sidewall style and product series that best match its restoration goals and intended use.
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.
Best 1926 Dodge 4 Cyl. Tires for Sale
Available 525-21 choices include Firestone and Excelsior bias-ply tires in Firestone Classic Bias Ply and Comp H series, with blackwall and wide whitewall presentations. Rim-width specifications also vary, so wheel compatibility is part of the comparison along with appearance.
Common questions for the 1926 Dodge 4 Cyl. usually center on its two tire sizes, wheel confirmation, bias-ply selection, sidewall appearance, and the checks worth making before putting an antique Dodge back on the road.
Tire Size & Fitment
What tire size fits a 1926 Dodge 4 Cyl.?
The 1926 Dodge 4 Cyl. is associated with two bias-ply tire sizes: 31X5.25 and 525-21. Those are not simply two ways of writing the same size. They represent different vintage sizing conventions, and they correspond to different wheel setups on the car.
The important next step is checking the wheels currently installed on the Dodge before choosing a tire. A car that has been restored, repaired, or updated over the years may not still be using its earlier wheel arrangement, so confirming rim diameter and overall wheel type matters before comparing available tires.
What size rim does a 1926 Dodge 4 Cyl. use?
The 1926 Dodge 4 Cyl. is tied to more than one rim diameter because its associated tire sizes do not share the same wheel size. The 31X5.25 fitment is tied to a 5.0-inch rim diameter, while the 525-21 fitment uses a 21-inch rim.
That makes wheel confirmation the most important fitment check on this vehicle. Antique cars often pass through decades of maintenance and restoration, and the wheel setup on the car today determines which tire size should be considered. Measuring the wheel and comparing it to the intended tire is the safest starting point.
Does the 1926 Dodge 4 Cyl. Base use the same tire size?
The 1926 Dodge 4 Cyl. Base is associated with the same two tire sizes used on the model overall: 31X5.25 and 525-21, both in bias-ply construction. That means the sub-model itself does not narrow the choice to one size automatically.
Selection still comes down to the actual wheels on the car. Once the wheel setup is confirmed, the buyer can focus on the style and product differences available in the matching size, such as blackwall versus wide whitewall in 525-21, rather than treating both fitments as universally interchangeable.
Choosing the Right Tire
What should I consider when choosing a 525-21 tire for a 1926 Dodge 4 Cyl.?
A 525-21 tire for a 1926 Dodge 4 Cyl. should first be chosen by confirming that the car is actually on 21-inch wheels. After that, the meaningful differences are brand, tire series, sidewall style, rim-width specification, and whether the tire suits the kind of restoration or road use planned for the car.
Firestone and Excelsior both appear in this size, but they are not identical offerings. Some 525-21 tires are blackwall, while another uses a wide whitewall treatment, and rim-width specifications also vary. Comparing those details helps match the tire to the wheel and to the car's visual presentation without assuming every 525-21 option serves the same purpose.
What sidewall styles are available for 1926 Dodge 4 Cyl. tires?
For the 1926 Dodge 4 Cyl., the available 525-21 products include both blackwall and wide whitewall sidewall styles. That gives an owner a meaningful appearance choice within the same vintage numeric bias-ply size rather than forcing a single visual presentation.
Blackwall usually supports a more understated traditional look, while a wide whitewall can create a more formal and decorative period-style presentation. Since sidewall treatment changes the car's overall visual character, it makes sense to choose the style after the correct size and wheel fitment are confirmed, not before.
What brands offer tires for the 1926 Dodge 4 Cyl.?
The available 525-21 tire choices for the 1926 Dodge 4 Cyl. include Firestone and Excelsior. Firestone appears in its Classic Bias Ply series, while Excelsior appears in the Comp H series, giving the buyer more than one traditional brand and series direction within the same basic fitment.
Brand alone should not be the only deciding factor on an antique vehicle like this. It is more useful to compare the exact tire series, sidewall treatment, and rim-width specification that go with each option, then choose the one that best suits the wheel, the car's presentation, and the owner's intended use.
Restoration & Appearance
Which tire should I choose for a period-style 1926 Dodge 4 Cyl.?
A period-style 1926 Dodge 4 Cyl. should start with the correct vintage size and bias-ply construction for the wheel setup on the car. In practice, that means confirming whether the Dodge is using the 31X5.25 fitment or the 525-21 fitment before narrowing the choice to a specific tire style.
Once the proper size is confirmed, appearance becomes the real decision. A blackwall supports a more restrained antique presentation, while a wide whitewall gives the car a more dressed-up look. Owners pursuing strict originality should compare their choice against marque references or restoration documentation for the individual vehicle.
Does correct tire fitment matter for a 1926 Dodge 4 Cyl. restoration?
Correct tire fitment matters a great deal on a 1926 Dodge 4 Cyl. because tire size affects stance, wheel compatibility, and the overall visual proportion of the car. On an antique vehicle, the wrong sizing format can look out of place even before any road-use concerns enter the picture.
Fitment also influences whether the restoration feels coherent when viewed alongside the wheels, body lines, and trim. Since this Dodge is associated with more than one vintage size format, confirming the car's actual wheel setup is essential. That step helps preserve both the car's appearance and a more historically appropriate tire presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1926 Dodge 4 Cyl.?
Modifications can absolutely affect tire fitment on a 1926 Dodge 4 Cyl. Changes to wheels, hubs, suspension height, brake components, or body clearance can alter which size works on the car and how much room remains around the tire once installed.
Even on an antique Dodge, the safest approach is to inspect what is physically on the vehicle today instead of assuming it still matches an earlier setup. Measuring wheel diameter and width, then checking clearance at the fenders and steering components, helps avoid choosing a vintage tire size that does not suit the current configuration.
What should I inspect before driving a 1926 Dodge 4 Cyl. on new tires?
Before driving a 1926 Dodge 4 Cyl. on new tires, inspect the wheels for damage or distortion and make sure the selected tire matches the wheel dimensions in use. It is also worth checking valve hardware, mounting condition, and whether the tires sit evenly with no obvious interference.
A short collector-car test drive should include attention to air retention, steering feel, and any signs of rubbing or unusual movement. Antique vehicles deserve extra caution because long periods of storage can leave other components aged even when the tires are fresh, so brakes, steering joints, and wheel fasteners also merit a careful look.
How should tires on a collector 1926 Dodge 4 Cyl. be maintained?
Tires on a collector 1926 Dodge 4 Cyl. should be inspected regularly for cracking, cuts, bulges, uneven wear, and gradual air loss, especially if the car is driven only occasionally. Antique vehicles often spend long periods parked, so tire condition can change from age and storage even when tread wear remains minimal.
Good collector-car maintenance also includes keeping the Dodge away from prolonged sunlight, excess heat, moisture, and ozone sources during storage. Pressure checks matter before road use, and the car should be looked over carefully after long dormant periods. Routine inspection is just as important as choosing the right vintage size in the first place.
