The 1930 Auburn 95 Series comes from an era when American automobiles balanced upscale design, road presence, and mechanical sophistication in a way that still draws restoration-minded owners today. Cars of this period rely heavily on proper tire fitment because tire shape, stance, and construction all influence both appearance and drivability. For the 1930 Auburn 95 Series, the primary fitment centers on bias-ply choices in 30X6.00 and 6.00-18, both tied to the vehicle’s 18-inch wheel setup. That makes the decision less about modernizing and more about choosing the right period-style size interpretation. Before selecting a tire, it is worth confirming which size matches the car’s existing wheels and restoration direction.
Which Tire Size Is Right for The 1930 Auburn 95 Series
The 1930 Auburn 95 Series uses two primary tire sizes, and both are bias-ply fitments tied to the same 18-inch wheel diameter. The first step is identifying which size is correct for the car’s present wheel and restoration setup, since an antique-style 30X6.00 and a numeric 6.00-18 describe tire dimensions in different ways even though they relate to the same general fitment range.
30X6.00 is an antique diameter-by-section size, meaning the first number refers to the tire’s approximate overall diameter of 30 inches and the second refers to an approximate section width of 6.00 inches. It is a bias-ply fitment suited to the pre-war tire conventions used on cars such as the 1930 Auburn 95 Series. This format is especially relevant for owners aiming to preserve a traditional early-1930s tire presentation and stance. It is a useful size to evaluate carefully if the car retains period-style wheels and the goal is to stay close to the visual character expected from the era.
6.00-18 is a numeric bias-ply size in which 6.00 represents the nominal tire section width in inches and 18 identifies the wheel diameter. On the 1930 Auburn 95 Series, this size places the fitment in a more familiar vintage numeric system while keeping the traditional bias-ply construction appropriate to the vehicle’s period. For many buyers, this size can be easier to interpret because the wheel diameter is stated directly in the size code. It is the right size to consider when confirming an 18-inch rim and comparing replacement tires for road use, restoration presentation, and wheel compatibility.
Sub-model fitment is straightforward here because the covered 1930 Auburn 95 Series 8 Cyl. uses the same two primary bias-ply tire sizes. Checking the exact sub-model still matters so the tire choice stays aligned with the car’s wheel setup and restoration approach.

Frequently Asked Questions
These FAQs focus on the tire sizes used on the 1930 Auburn 95 Series, how the two bias-ply formats differ, and what to check for wheel fitment, restoration presentation, and safe road use.
Tire Size & Fitment
What tire size fits a 1930 Auburn 95 Series?
The 1930 Auburn 95 Series uses two primary bias-ply tire sizes: 30X6.00 and 6.00-18. Those sizes reflect two vintage sizing conventions for this vehicle, with 30X6.00 using an antique diameter-by-section format and 6.00-18 using a numeric bias-ply format tied directly to an 18-inch rim.
Choosing between them starts with confirming what wheels are actually on the car. A restored or long-owned Auburn may have had wheel changes over time, so the size in use now should be matched against the wheel diameter and the overall look you want, rather than assuming either size belongs on every existing setup without checking.
What size rim does a 1930 Auburn 95 Series use?
The 1930 Auburn 95 Series uses an 18-inch rim. That rim diameter is stated directly in the 6.00-18 size, and it also aligns with the vehicle’s wheel specification for the alternate 30X6.00 fitment used on this application.
Rim diameter is the first hard measurement to verify before ordering tires for a pre-war car. The wheel should also be inspected for condition, width suitability, and any signs of repair or replacement, since collector vehicles sometimes carry older service parts that differ from the configuration a buyer expects from the model name alone.
What does 30X6.00 mean on a 1930 Auburn 95 Series?
On a 1930 Auburn 95 Series, 30X6.00 is an antique diameter-by-section size. The 30 refers to the tire’s approximate overall diameter in inches, while 6.00 refers to its approximate section width, making it a format commonly seen on earlier vintage and pre-war vehicles.
That matters because this size expresses the tire differently than a later numeric format such as 6.00-18. Owners comparing replacements should look beyond the lettering style and confirm that the tire matches the wheel diameter, the physical space in the car’s wheel openings, and the visual profile they want for a traditional early-1930s presentation.
Choosing the Right Tire
What should I consider when choosing a 30X6.00 or 6.00-18 tire for a 1930 Auburn 95 Series?
Start with the tire size that matches the car’s actual wheel setup, since the 1930 Auburn 95 Series uses both 30X6.00 and 6.00-18 as primary bias-ply fitments. After size confirmation, the next priorities are keeping the proper 18-inch rim relationship and choosing a tire that suits the car’s intended role, whether that is restoration display, local touring, or occasional road use.
Appearance also plays a major role on a car from this period. A tire that preserves the right stance and side profile can change how authentic the Auburn looks, so it helps to evaluate the existing wheels, the body-to-tire proportions, and how closely the replacement supports the period-style presentation you want from the finished car.
How do I choose between the available 30X6.00 and 6.00-18 tire formats for a 1930 Auburn 95 Series?
The choice comes down to matching the format already used by the car and understanding what each code is telling you. A 30X6.00 tire emphasizes overall diameter and section width in an antique format, while 6.00-18 gives a nominal section width paired with the 18-inch rim diameter in a more familiar numeric bias-ply format.
That difference is important on a restoration because the tire size affects more than fitment language. Comparing the wheel itself, the way the car currently sits, and the kind of presentation you want at shows or on the road will usually make the right direction clearer before any final tire selection is made.
Why does tire presentation matter when selecting tires for a 1930 Auburn 95 Series?
Tire presentation matters on a 1930 Auburn 95 Series because the vehicle’s visual balance depends heavily on tire height, sidewall presence, and traditional construction. On pre-war automobiles, the tires are a prominent part of the profile, so the wrong sizing style or visual character can change the way the car sits and reads from the side.
A buyer choosing replacement tires should think about more than simple mountability. Matching the car’s restoration level, wheel style, and intended use helps narrow the choice, and it is wise to review period photos, marque-club resources, or restoration references if a highly authentic appearance is part of the goal.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Auburn 95 Series?
For a period-style 1930 Auburn 95 Series, the right starting point is one of the two primary bias-ply sizes used on the car: 30X6.00 or 6.00-18. Both preserve the traditional construction expected on a vehicle of this era, so the decision usually comes down to which size matches the wheels on the car and the look of the restoration.
A strong period-style result depends on proportion as much as fitment. Reviewing the car’s current wheels, stance, and restoration documentation can help separate a merely usable tire from one that supports the Auburn’s pre-war visual character in a way that feels appropriate on display and on the road.
Does correct tire fitment matter for a 1930 Auburn 95 Series restoration?
Correct tire fitment matters a great deal on a 1930 Auburn 95 Series restoration because tire height, width, and construction are central to the car’s overall appearance. On a pre-war automobile, an incorrect tire format can make the wheel openings, ride height, and body proportions look noticeably off even before the car leaves the garage.
Fitment also affects usability. A tire that matches the wheel properly and respects the available clearance is easier to evaluate for safe road service, while a poorly matched choice can complicate steering clearance, fender space, and visual authenticity. That makes tire selection one of the finishing details worth getting right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Auburn 95 Series?
Yes, modifications can affect tire fitment on a 1930 Auburn 95 Series even when the tire size itself is one of the correct primary sizes. Wheel replacements, brake work, suspension repairs, altered ride height, or bodywork changes can all influence how a 30X6.00 or 6.00-18 tire sits within the available space.
That is why an older collector car should be measured and inspected in its present form before new tires go on. Checking wheel diameter, wheel condition, steering clearance, and fender space helps avoid assuming that a correct nominal size will behave the same way on a car that has been changed over decades of use or restoration.
What should I inspect before driving a 1930 Auburn 95 Series on new tires?
Before driving a 1930 Auburn 95 Series on new tires, inspect the wheels, valve hardware, and mounting condition, then confirm the tires are seated properly and inflated consistently. It also helps to look over suspension and steering components, since loose or worn parts can make a freshly mounted set of bias-ply tires feel unsettled even when the tires themselves are correct.
A short, careful shakedown drive is usually the best next step. Pay attention to pulling, vibration, unusual rubbing, and any sign of air loss, then recheck pressure after the first outing. On a low-use collector vehicle, that early inspection is often just as important as the initial installation.
How should 30X6.00 or 6.00-18 tires on a collector 1930 Auburn 95 Series be maintained?
Collector-car tires on a 1930 Auburn 95 Series should be maintained with regular pressure checks, visual inspections, and careful storage habits. Bias-ply tires on low-mileage vehicles can age out before they wear out, so sidewall cracking, flat spotting from long storage, cuts, bulges, and persistent air loss all deserve attention even if the tread still looks usable.
Storage conditions matter almost as much as road use. Keeping the Auburn away from prolonged sunlight, moisture, and ozone sources can help preserve tire condition, and moving the car periodically reduces the chance of long-term flat spotting. A pre-drive inspection is wise any time the car has been sitting for an extended period.
