The 1926 Essex 6 Cyl. comes from an era when affordable American cars were helping bring dependable motoring to a much wider public, and tire fitment was still closely tied to the wheel and chassis setup on the car itself. That makes size verification especially important on a surviving example today. This Essex 6 Cyl. is associated with two bias-ply tire sizes, 30X4.75 and 4.75-21, so the first step is confirming which wheel and rim diameter the car actually carries. For many owners, the real decision then becomes preserving a proper period-style look while choosing the size that matches the existing wheels and intended road use.
Which Tire Size Is Right for The 1926 Essex 6 Cyl.
The 1926 Essex 6 Cyl. uses two primary tire sizes, and they do not share the same rim diameter. One setup uses 30X4.75, while another uses 4.75-21, both in bias-ply construction. Before selecting a tire, confirm the exact wheel and rim diameter on the car, since that determines which size applies far more than appearance alone.
30X4.75 is an antique diameter-by-section size, meaning the first number refers to the tire's approximate overall diameter and the second refers to its section width in inches. On the 1926 Essex 6 Cyl., this is a bias-ply fitment tied to a 5-inch rim diameter, which is very different from later sizing conventions and easy to misread if only the section width is considered. This type of sizing suits owners trying to retain an early, period-style tire presentation. It should be chosen only after the wheel itself is confirmed, since the unusual rim diameter makes verification especially important.
4.75-21 is a numeric bias-ply size in which 4.75 refers to the nominal section width in inches and 21 identifies the rim diameter. For the 1926 Essex 6 Cyl., it represents a more familiar vintage bias-ply format than 30X4.75, but it still requires careful wheel confirmation because the 21-inch rim is specific and not interchangeable with the other primary fitment. This size is a practical choice for an owner whose car already carries 21-inch wheels and who wants to stay with the traditional construction and look appropriate to the period.
The covered sub-model fitment is simple in one sense and critical in another: the 1926 Essex 6 Cyl. Base is associated with both primary tire sizes. Checking the actual wheel and rim diameter on the car matters more than the sub-model name alone before any tire is selected.

The 1926 Essex 6 Cyl. Base is associated with both 30X4.75 and 4.75-21 bias-ply fitments. That means tire selection starts with confirming which wheel setup is on the car today, then choosing the period-style tire size that matches that rim diameter 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.
Frequently Asked Questions
Owners of a 1926 Essex 6 Cyl. usually need clarity on the two primary tire sizes, the unusual rim differences between them, and the checks that matter before putting an early car back on the road.
Tire Size & Fitment
What tire size fits a 1926 Essex 6 Cyl.?
The 1926 Essex 6 Cyl. is associated with two primary tire sizes: 30X4.75 and 4.75-21. Both are bias-ply fitments, but they are not the same type of size and they do not use the same rim diameter, so they should not be treated as interchangeable choices.
The correct selection depends on the wheels actually mounted on the car. A surviving Essex may have been changed over time, so the safest approach is to verify the rim diameter and compare the marking on the existing tire or wheel before choosing a replacement.
What size rim does a 1926 Essex 6 Cyl. use?
The 1926 Essex 6 Cyl. is associated with two different rim diameters depending on tire size. The 30X4.75 fitment uses a 5-inch rim diameter, while the 4.75-21 fitment uses a 21-inch rim diameter, which makes wheel confirmation essential before replacement.
That difference is too large to treat casually, especially on an early vehicle where wheel and tire conventions varied more than on later cars. Measuring the wheel and checking its markings can prevent ordering the right-looking tire in the wrong rim diameter for the car.
What does 30X4.75 mean on a 1926 Essex 6 Cyl.?
30X4.75 is an antique diameter-by-section tire size. The 30 refers to the tire's approximate overall diameter in inches, while 4.75 refers to its section width. On the 1926 Essex 6 Cyl., this size is a bias-ply fitment used on a 5-inch rim diameter.
That sizing format is very different from later numeric and metric systems, so it can be misunderstood by owners more familiar with modern tire markings. The practical takeaway is to match both the tire size and the wheel itself, not just the width number in the marking.
Choosing the Right Tire
What should I consider when choosing a 30X4.75 or 4.75-21 tire for a 1926 Essex 6 Cyl.?
Start with the actual wheel setup on the car, because the 1926 Essex 6 Cyl. is associated with two different bias-ply sizes that use very different rim diameters. The first decision is not appearance or brand preference, but whether the car is equipped for 30X4.75 or 4.75-21.
After confirming the wheel, think about how the car will be used. A car intended mainly for shows may prioritize a traditional period-style presentation, while a car driven more regularly still needs the correct size, sound wheel condition, and enough clearance for safe operation.
How do I choose between the available 1926 Essex 6 Cyl. tire sizes?
Choosing between 30X4.75 and 4.75-21 is not a matter of preference alone, because both are primary fitments tied to different rims. The right choice depends on which wheel diameter is on the car today, and both sizes remain within traditional bias-ply construction for this Essex.
That means the best path is to inspect the wheels directly rather than relying on assumption. Cars from this period may have seen wheel, hub, or restoration changes over the decades, so matching the tire to the current hardware is more important than selecting by appearance.
Why does the 1926 Essex 6 Cyl. have more than one tire size?
The 1926 Essex 6 Cyl. is tied to two different primary tire sizes because early automotive fitment was not always as standardized as later passenger cars. In this case, both 30X4.75 and 4.75-21 are bias-ply fitments, but they represent different sizing systems and different rim diameters.
For an owner, that means the car should be treated as a wheel-confirmation vehicle first. Looking at the existing wheel diameter, tire marking, and overall setup helps narrow the correct replacement, especially if the car has been restored, stored long term, or changed during earlier ownership.
Restoration & Appearance
Which tire should I choose for a period-style 1926 Essex 6 Cyl.?
For a period-style 1926 Essex 6 Cyl., the starting point is staying with the correct primary bias-ply size for the wheels on the car, either 30X4.75 or 4.75-21. Both sizes reflect vintage construction and preserve the traditional look that suits a mid-1920s automobile.
Appearance should come after wheel verification, not before it. If historical accuracy is especially important, compare the car against marque references, restoration photos, or period literature so the tire choice supports both the visual character of the car and the actual wheel hardware.
Does correct tire fitment matter for a 1926 Essex 6 Cyl. restoration?
Correct tire fitment matters a great deal on a 1926 Essex 6 Cyl. because the tire contributes strongly to the car's stance, visual balance, and authentic early-car character. Using the right primary size for the wheel helps the restored vehicle look settled and appropriate rather than visually off-scale.
Fitment also affects practicality, not just appearance. A mismatch between tire and rim diameter can halt a project quickly, and even a restoration-focused car still needs proper wheel compatibility before road use, display, or transport to events.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1926 Essex 6 Cyl.?
Yes, modifications can affect tire fitment on a 1926 Essex 6 Cyl. even when the tire size itself appears correct. Wheel changes, brake updates, suspension work, or earlier restoration decisions can alter the dimensions that matter, especially on a vehicle from the 1920s where hardware may no longer be fully original.
That is why wheel diameter should be physically confirmed before choosing between 30X4.75 and 4.75-21. It also helps to check steering clearance, fender space, and the condition of the wheels themselves so the replacement tire matches the car's current setup rather than its assumed setup.
What should I inspect before driving a 1926 Essex 6 Cyl. on new tires?
Before driving a 1926 Essex 6 Cyl. on new tires, inspect the wheels, valve hardware, and tire mounting carefully, then confirm inflation, tread condition, and sidewall condition after installation. Early vehicles also benefit from a close look at wheel integrity and any signs of looseness or age-related deterioration.
A short, cautious test drive is a smart follow-up. Listen for rubbing, confirm steering moves freely lock to lock, and recheck air pressure after the first miles so the car's new tires are working with the existing wheels and chassis rather than exposing an unnoticed fitment issue.
How should 30X4.75 or 4.75-21 tires on a collector 1926 Essex 6 Cyl. be maintained?
Tires on a collector 1926 Essex 6 Cyl. should be checked regularly for air loss, cracking, cuts, bulges, and uneven wear, even if the car is driven only occasionally. Long storage can be hard on vintage tires, so condition matters just as much as tread depth on an early collector car.
Storage habits make a difference as well. Keeping the car away from prolonged sunlight, moisture, heat, and ozone sources helps preserve tire condition, and periodic inspection before each outing is a sensible routine for either 30X4.75 or 4.75-21 bias-ply fitments.
