Paige 45 Series Tires

Paige built the 45 Series during the later years of the independent American car market, when manufacturers were moving quickly from earlier high-profile tire conventions into more modern wheel and tire standards. A 1927 Paige 45 Series sits right in that transition, which makes tire selection more involved than it first appears. The same model year is associated with two different size formats, one using an older outside-diameter style and one using a newer rim-based numeric designation. Anyone selecting tires for a Paige 45 Series should first confirm which wheel and rim setup is actually on the car, then match the tire size format to that configuration.

Paige 45 Series Tire Size Guide

The Paige 45 Series uses 2 distinct tire sizes across the 1927 model year. One size appears in an antique diameter-by-section format, where the leading number is the tire's outside diameter rather than the wheel diameter, while the other uses a newer numeric rim-based format. That mix points to a year where wheel and tire conventions were in transition, so the exact configuration on the car matters before choosing a tire.

30X5.251927Antique diameter-by-section

30X5.25 is one of the sizes associated with the 1927 Paige 45 Series. In this format, 30 indicates the tire's overall outside diameter in inches and 5.25 indicates nominal section width, while the wheel diameter must be confirmed from the actual rim because it is not stated in the size code. Choose this size only if the car carries the earlier-style wheel setup that matches this designation.

5.25-201927Numeric bias-ply

5.25-20 is also associated with the 1927 Paige 45 Series. In this numeric format, 5.25 is the nominal section width in inches and 20 is the rim diameter in inches, reflecting the later rim-based sizing convention. Choose this size if the car is equipped with 20-inch rims and verify the wheel marking or original vehicle records before final selection.

Paige 45 Series Tires by Year

The year listing breaks the Paige 45 Series down by model year so you can match the car to the sizes associated with that period. In 1927, two sizes are listed, so confirm the specific wheel and tire setup on the car rather than relying on the year alone. The leading number in 30X5.25 is the tire's outside diameter, not the wheel size, while 5.25-20 identifies a 20-inch rim directly.

Frequently Asked Questions

The FAQ below focuses on the 1927 Paige 45 Series size split, the difference between antique and numeric tire designations, and the practical checks that matter when matching tires to an unrestored or restored car.

Size Basics & Fitment

The 1927 Paige 45 Series is associated with two tire sizes: 30X5.25 and 5.25-20. Those are not simply two ways of writing the same thing. 30X5.25 is an older diameter-by-section style size, while 5.25-20 is a later numeric size that directly identifies a 20-inch rim.

The practical takeaway is that the correct tire depends on the actual wheel setup on the car. Start by checking the rim itself, the existing tire markings if they are still legible, and any original service information that came with the vehicle. On a 1927 Paige 45 Series, the year alone is not enough to pick the tire with confidence.

On a Paige 45 Series, 30X5.25 is an antique diameter-by-section size. The 30 refers to the tire's overall outside diameter in inches, and the 5.25 refers to the nominal section width. Unlike a modern size, the wheel diameter is not built into that code, so the rim size cannot be read from 30X5.25 alone.

That matters because many buyers see the first number and assume it is the wheel diameter, which would be incorrect here. When a Paige 45 Series carries this style of marking, inspect the wheel and compare it with the car's existing equipment before selecting a replacement. Antique size codes require a little more verification than later rim-based sizes.

A 1927 Paige 45 Series has two listed tire sizes because that model year sits in a transition between two sizing conventions. One is the older 30X5.25 format, which emphasizes outside diameter and section width. The other is 5.25-20, which identifies the section width and a 20-inch rim directly.

For an owner or restorer, that means the exact wheel and equipment combination on the car should drive the decision. Original wheels, later replacements, or past restoration work can all affect which size is actually correct today. When a single year shows more than one size format, the safest approach is to verify the hardware first and treat the year listing as a starting point.

The Paige 45 Series uses at least one setup with a 20-inch rim, shown by the 5.25-20 size. The 30X5.25 size does not state the rim diameter in the size code, because its leading number gives outside tire diameter rather than wheel diameter. That means the wheel diameter must be confirmed directly on the car when dealing with the antique-style size.

This is one of the most important checks on a 1927 Paige 45 Series. If the car still wears original or long-installed wheels, look for stamped markings or compare the wheel to period references for the specific chassis and body configuration. A correct tire choice starts with confirming the rim diameter before comparing tread, sidewall, or brand.

Buying the Right Tire

The best way to confirm tire size on a 1927 Paige 45 Series is to inspect the wheels and compare them with the tire designation already associated with the car. If the wheel setup corresponds to a rim-based numeric size, 5.25-20 is the relevant listing. If the car carries an earlier-style arrangement marked by outside diameter and section width, 30X5.25 is the size to investigate.

Begin with the wheel itself, then compare any surviving markings on the current tires, period literature, restoration records, and marque knowledge from Paige specialists. Many collector cars have been altered over the years, so physical verification matters more than assumption. On a transition-era car like the Paige 45 Series, confirming the wheel arrangement is the key step.

Made-to-order means a tire is produced as a special-build collector application rather than as a routine mass-market item. That designation is common in vintage and specialty sizes, especially where demand is limited and correctness matters more than volume. For a Paige 45 Series, it signals that the tire is part of a niche restoration market rather than a modern replacement category.

For the buyer, the important point is to treat the tire as a specialized fitment that deserves careful verification before selection. Check the exact size format, wheel setup, and intended use of the car before choosing among available options. That extra attention helps avoid ordering a tire that matches the year in broad terms but not the specific configuration on the vehicle.

Paige 45 Series buyers may encounter more than one style of vintage tire construction and sizing convention tied to this model year, even though the two listed sizes already tell most of the story. The older 30X5.25 format belongs to an earlier style of tire identification focused on outside diameter and section width. The 5.25-20 size belongs to the later rim-based system that became easier for owners and service shops to identify by wheel diameter.

That difference matters in restoration planning because the tire style should suit the wheel design and the period presentation of the car. Owners preserving a very original appearance often pay close attention to the era implied by the size format itself. Even when two sizes appear close in width, the underlying wheel standard can be very different on a Paige 45 Series.

Maintenance & Longevity

A Paige 45 Series should be stored in a cool, dry, dark space with the tires protected from sunlight, ozone sources, and prolonged contact with oil or solvents. Keep the car on a clean surface and maintain inflation appropriate to the tire and wheel being used. If the car will sit for long periods, moving it slightly from time to time can help reduce flat spotting.

Collector cars benefit from stable conditions more than frequent movement. Avoid storing a Paige 45 Series near electric motors, battery chargers, heaters, or windows that expose the tires to ultraviolet light. If the car is displayed for extended periods, periodic inspection of sidewalls, beads, and tread helps catch age-related issues before they become serious.

Tires on a Paige 45 Series should be inspected before every drive and given a more thorough review several times a year, even if the car sees very little mileage. Look for cracking, tread separation, sidewall damage, uneven wear, valve issues, and any signs that the tire is not seating correctly on the wheel. On an older collector car, time and storage conditions can matter as much as miles driven.

A close inspection routine is especially important because a Paige 45 Series may carry vintage-style tires and wheels that do not behave like modern daily-driver equipment. If the car has been parked for a season, inspect again before rolling it any distance. Many owners also include the spare in the inspection schedule, since it may be the oldest tire on the car.

Tires on a Paige 45 Series should be replaced when age, cracking, hardening, bulges, separation, or other structural concerns appear, even if the tread still looks usable. Collector-car tires often age out long before they wear out. A tire can look presentable on the outside and still be unsuitable for driving if the casing has deteriorated with time.

That is particularly important on a car from the 1920s, where the entire driving environment is less forgiving than on a modern vehicle. If a Paige 45 Series has older tires of uncertain history, a specialist inspection is worthwhile before any touring use. Visual tread depth alone is not a reliable measure of serviceability on antique and transition-era tires.

Restoration & Authenticity

The Paige 45 Series is associated here with two period-correct size conventions for 1927: 30X5.25 and 5.25-20. That tells you the model year overlaps an era when more than one tire designation could be relevant depending on the wheel and equipment on the specific car. The original tire for one Paige 45 Series may not match another if the wheel setup differs.

For restoration accuracy, the best reference is the car's own equipment combined with period factory literature, surviving service records, and marque-club knowledge. A judge or knowledgeable enthusiast will usually look for consistency between wheel, tire size, and the car's presentation. Matching the tire convention to the actual configuration is more important than choosing by year alone.

Correct tire fitment can absolutely affect the value, presentation, and judging of a Paige 45 Series. Tires are a highly visible part of the car's stance, profile, and era correctness, and judges often notice when the size convention does not match the wheel or overall restoration approach. On an antique American car, an incorrect tire can change both appearance and perceived authenticity.

Owners restoring a Paige 45 Series for concours, tours, or serious collection use should aim for a tire size and style that fits the exact wheel arrangement on the car. Marque clubs and experienced restorers are often the best tie-breakers when period literature leaves room for interpretation. Getting the tires right helps the whole restoration look coherent and historically believable.

A correct sidewall style for a Paige 45 Series restoration should suit the car's year, body presentation, and the historical look the owner is pursuing. Late-1920s cars could appear with more than one sidewall treatment depending on market position and restoration philosophy. The right answer is not purely cosmetic, because sidewall style helps define whether the finished car looks authentically period.

The best approach is to match the sidewall style to period photos, surviving original examples, and the standard used by the events where the Paige 45 Series will appear. Touring restorations and judged restorations may weigh appearance differently, but both benefit from historical consistency. Once the correct tire size is confirmed, sidewall style becomes an important finishing detail.

Safety & Road Use

A properly selected and properly maintained tire can be suitable for careful public-road use on a Paige 45 Series, but the tire is only one part of the equation. A 1927 automobile has very different braking, steering, suspension, and traffic-speed realities than a modern car. Safe use depends on the entire vehicle being mechanically sound and operated within the limits of its design.

That means a Paige 45 Series should be driven conservatively and with a route plan that suits an antique car. Before regular road use, inspect not just the tires but also wheels, bearings, steering joints, brakes, and inflation condition. A correct tire helps, but it does not turn a 1927 car into a modern highway vehicle.

Before driving a Paige 45 Series, check tire condition, inflation, visible cracking, valve stems, wheel attachment, and any signs of sidewall damage or separation. Also inspect the spare, because it may be needed on a car that is operating on older-style tire equipment. Tire checks should be part of a broader pre-drive routine that includes fluids, brakes, steering response, and wheel security.

On a collector car, a few minutes of inspection can prevent the most common roadside problems. Pay close attention if the Paige 45 Series has been parked for weeks or months, or if it was recently restored and has seen little real road use. A short test roll and visual check after moving the car can reveal issues that were not obvious at rest.

A Paige 45 Series should be driven at conservative speeds that respect both the age of the vehicle and the design limits of vintage-style tires. Even when the tires are new, the rest of the car remains a 1927 machine with period steering, braking, and chassis behavior. Appropriate speed is governed as much by mechanical condition and road environment as by tire choice.

In practical terms, owners usually enjoy a Paige 45 Series best on secondary roads, tours, and measured-distance outings rather than fast modern traffic. Build speed gradually, stay well within the car's comfort zone, and reassess if the steering, braking, or ride feels unsettled. A cautious pace preserves both safety and the long-term well-being of the car and its tires.
