1906 Packard Tire Fitment Guide

1906 Packard vehicles use two tire sizes: 34X4.5 and 34X4. The 34X4.5 size fits both the 1906 Packard Model 24 and the 1906 Packard Model S, and it mounts on a 25-inch rim. The 34X4 size fits the 1906 Packard Model S and mounts on a 26-inch rim. Where load figures are shown, 34X4.5 products include examples rated at 1250 pounds at 65 psi and 1252 pounds at 60 psi, while 34X4 includes an example rated at 1102 pounds at 60 psi.

That means a 1906 Packard owner should begin by identifying both the model and the actual wheel diameter on the car. A Model 24 follows the 34X4.5 path, while a Model S may require either size depending on its wheel setup. Because the two sizes do not share the same rim diameter, they are not interchangeable just by preference. If the car has been restored over the years, measuring the wheel and comparing it against the tire size already fitted is the safest first step before choosing sidewall style or brand.

On a 1906 Packard, 34X4.5 is an antique diameter-by-section tire size. The first number refers to a nominal 34-inch overall tire diameter, while the second number refers to a nominal 4.5-inch section width. It is a brass-era bias-ply high-pressure tire size, and the products offered in this fitment mount on a 25-inch rim rather than a 34-inch wheel.

That older sizing system can confuse modern buyers because the leading number is not the wheel diameter. For a 1906 Packard owner, the practical takeaway is that 34X4.5 is a complete fitment description for a specific early high-pressure tire type, not just a rough measurement. If your car uses this size, the next choice is usually between Blackwall, All White, or Wide Whitewall presentation and among the available vintage-style brands, rather than deciding between different construction types.

No, all 1906 Packard models do not use the same tire size. The Model 24 uses 34X4.5, while the Model S appears with both 34X4.5 and 34X4. The shared size across the year is 34X4.5, but 34X4 is limited to the Model S and uses a different rim diameter, so there is real model-specific variation within the lineup.

That variation matters because a buyer cannot assume that any tire listed for a 1906 Packard will fit every 1906 Packard. If you have a Model S, verify whether the car is set up for the 25-inch rim used with 34X4.5 or the 26-inch rim used with 34X4. Once the correct size is established, you can narrow further by sidewall look and brand family without guessing across incompatible wheel diameters.

1906 Packard tires are offered in several period-style sidewall treatments depending on size. In 34X4.5, available styles include Blackwall, All White, and Wide Whitewall. In 34X4, available styles include Blackwall and Wide Whitewall. All of these offerings are bias-ply tires suited to brass-era Packard applications, but the sidewall presentation changes the visual character of the car considerably.

A buyer restoring a 1906 Packard for formal presentation will usually choose sidewall style as much for appearance as for fitment. Blackwall gives the most understated early-car look, while white sidewall treatments create a brighter, more dressed presentation. Event standards and period photographs can influence which approach feels right for a specific body style or restoration philosophy, so it is worth comparing the finished look you want before settling on a particular sidewall treatment.

Several established vintage tire brands serve 1906 Packard fitments. The 34X4.5 size is available from BFGoodrich, Firestone, and Universal Vintage Tire. The 34X4 size is available from Michelin, BFGoodrich, Firestone, and Universal Vintage Tire. All are offered as bias-ply tires suitable for brass-era applications, but each brand family brings its own sidewall combinations and series identity.

That gives a 1906 Packard owner room to choose around restoration goals rather than around fitment alone. One brand may offer the sidewall look you want in a given size, while another may appeal because of its historic styling cues or series presentation. Since the size itself must be correct before anything else, treat the brand decision as the finishing layer once you have confirmed whether your Packard belongs in 34X4.5 on a 25-inch rim or 34X4 on a 26-inch rim.

For 1906 Packard fitments, BFGoodrich and Firestone overlap in both major sizes but differ in sidewall treatments and the published figures attached to some products. In 34X4.5, BFGoodrich appears in Blackwall and Wide Whitewall form, while Firestone appears in All White form with a listed capacity of 1252 pounds at 60 psi; BFGoodrich in that size includes an example listed at 1250 pounds at 65 psi. In 34X4, BFGoodrich appears in Wide Whitewall form, while Firestone appears in Blackwall form with a listed capacity of 1102 pounds at 60 psi.

For a 1906 Packard buyer, that means the comparison is less about replacing one modern performance category with another and more about choosing the visual presentation and published spec set that best matches the car’s intended use. If you are narrowing between the two brands, compare the exact sidewall style you want, the tire’s stated size, and any listed load-and-pressure pairing for the product you are considering rather than assuming all offerings within a size are identical.

1906 Packard tire offerings here identify rim diameter by size, with 34X4.5 mounting on a 25-inch rim and 34X4 mounting on a 26-inch rim. That gives a clear diameter target for each fitment path. The listings do not present a published rim-width range for these brass-era sizes, which is common with early high-pressure tires where wheel construction and original application matter as much as modern width charts.

In practice, a 1906 Packard owner should verify the wheel already on the car rather than working from year and make alone. Diameter must match first, especially on Model S cars that can use more than one size family. Once the diameter is confirmed, compare the tire size on the car, inspect the condition and type of the rim, and involve a Packard or brass-era specialist if the wheels have been changed during an older restoration.

1906 Packard tires in these brass-era sizes are offered as early bias-ply high-pressure tires, but the individual product listings here do not carry TT or TL markings alongside the size. That means the buyer should confirm the specific tire and wheel combination before assuming tube fitment details. On automobiles of this age, tube use is often tied closely to the original style of wheel and rim construction rather than to a modern tubeless expectation.

The practical step is to inspect the wheel on the car and verify the exact setup before finalizing the tire choice. If your 1906 Packard retains original-style wood artillery or other early clincher-era hardware, tube-related requirements should be checked carefully with the tire manufacturer’s guidance and with a marque specialist familiar with early Packard wheel assemblies. It is better to resolve that during fitment planning than after a tire has already been selected for appearance alone.

A 1906 Packard should be stored in a cool, dry, dark environment away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber. Bias-ply brass-era tires also benefit from being kept clean and from avoiding long periods on damp concrete. If the car will sit for an extended season, rolling it periodically or supporting it to reduce constant load on one contact patch can help preserve shape and appearance.

Those habits matter because collector cars often age their tires by time and storage conditions more than by mileage. A well-kept 1906 Packard that is driven only occasionally can still develop sidewall checking, pressure loss, or flat-spotting if it sits in one place too long. Covering the tires from light, maintaining inflation during storage, and checking them again before the first drive of the season will do more for longevity than simply leaving the car parked and untouched.

Tires on a 1906 Packard should be evaluated by age as much as by wear, because brass-era collector vehicles often accumulate very few miles. A useful rule is to inspect them closely once they reach the five- to seven-year range, then treat ten years as a serious replacement point even if the tread still looks serviceable. The DOT-style age habit remains helpful even on reproduction collector tires: the calendar matters as much as visible wear.

That approach keeps a low-use Packard from riding on old rubber that looks better than it really is. Sidewall cracking, hardening, repeated pressure loss, and casing distortion are better retirement signals than tread depth alone on an early touring car. If the tires came with the car and their age is uncertain, establish a fresh baseline rather than assuming they are suitable because they still hold air or because the car is driven only to shows.

Tires on a 1906 Packard should be inspected before every drive and again before any longer outing or tour. Look for sidewall cracking, cuts, bulges, exposed fabric, uneven wear, and signs that the tire has shifted or deteriorated around the rim area. Pressure retention also matters on a brass-era car because low inflation can quickly affect steering feel, ride height, and casing stress.

A quick inspection routine is especially important on an early Packard because the car’s age magnifies the consequences of a preventable tire issue. Include the spare in the same check, and pay attention to valve-stem condition and any tube-related service details if your wheel setup requires them. Catching a problem in the garage is far better than discovering it after the car has warmed up on the road or after it has already damaged a scarce original rim.

The 1906 Packard Model 24 used brass-era bias-ply high-pressure tire construction, and the listed fitment for that model is 34X4.5. That aligns with what restorers expect from a premium American automobile of 1906, long before radial tires entered passenger-car use. A specific original-equipment brand should not be assumed from current reproduction offerings alone, because period supply could vary by market, dealer practice, and restoration history.

For restoration work, the most important points are matching the correct size, the correct early construction type, and an appropriate sidewall appearance for the way the car will be judged or displayed. If your Packard is headed for marque competition, compare your choice against period Packard literature, surviving photos, and Packard club guidance. That keeps the restoration focused on what judges and knowledgeable enthusiasts are most likely to notice first.

Correct tire fitment matters a great deal when showing a 1906 Packard, especially because brass-era cars wear their wheels and tires so prominently. Judges and knowledgeable enthusiasts often notice whether the tire size suits the car, whether the construction is appropriate to the period, and whether the sidewall treatment looks consistent with the restoration’s era and presentation. A visibly incorrect size or an obviously out-of-era look can distract from an otherwise strong car.

That does not always mean every event demands the same detail level, but serious authenticity standards usually reward getting the fundamentals right. On a 1906 Packard, that starts with choosing 34X4.5 or 34X4 correctly for the model and wheel setup, then selecting a sidewall style that supports the restoration’s intended appearance. Event rules and marque-club judging guides are the best final reference if the car is being prepared for points-based competition.

For a 1906 Packard restoration, the difference between 34X4 and 34X4.5 is not cosmetic shorthand for the same tire. Both are brass-era bias-ply sizes with a nominal 34-inch overall diameter, but 34X4 is the narrower section size and mounts on a 26-inch rim, while 34X4.5 mounts on a 25-inch rim. Within this year, 34X4.5 fits both the Model 24 and Model S, while 34X4 is tied specifically to the Model S.

That means authenticity depends on matching the tire to the actual wheel and model configuration rather than picking whichever size looks close. A restoration that uses the wrong rim-diameter family will stand out to experienced brass-era observers even if the tire itself is beautifully finished. Before finalizing a tire for show use, confirm the wheel on the car and compare it to period references so the restoration reflects the Packard’s proper early fitment character.

1906 Packard tires in these sizes are reproduction bias-ply brass-era tires intended for antique vehicle use, but no speed ratings are shown for the available 34X4.5 or 34X4 offerings. On a car of this age, safe road use depends at least as much on wheel condition, brakes, steering, suspension, and overall mechanical soundness as on the tire alone. A correctly fitted new tire is important, but it does not turn a brass-era Packard into a modern highway car.

The practical takeaway is to match the tire to the car correctly, keep speeds sensible, and treat longer modern-road use with respect for the Packard’s age and design. Before any sustained drive, confirm inflation, inspect each casing carefully, and make sure the wheels themselves are sound. If the car is used mainly for parades, local tours, and exhibition driving, selecting the proper size and maintaining the tire well will matter more than chasing a capability the vehicle was never built around.

Inflation pressure for 1906 Packard tires should follow the tire size and the specific product’s published load-and-pressure information, not a one-pressure-fits-all rule. In 34X4.5, listed examples include 1250 pounds at 65 psi and 1252 pounds at 60 psi. In 34X4, a listed example shows 1102 pounds at 60 psi. Those figures are tied to individual tires, so they should not be transferred casually from one size or product to another.

A careful owner should use the original Packard literature as a historical reference point, then compare that against the reproduction tire’s own rated pressure guidance. Because these are early high-pressure tires, even modest underinflation can affect ride and steering noticeably. Keep all four tires matched appropriately, check pressure when cold, and avoid assuming that the same psi belongs on both sizes simply because they are used within the same year and make.

Before taking a 1906 Packard on a longer drive, inspect each tire for cracking, cuts, bulges, irregular wear, and proper cold inflation, and do not forget the spare. Check that the tire size on the car matches the wheel diameter it is supposed to serve, since 34X4.5 and 34X4 use different rims. A broader pre-drive inspection should also include wheel integrity, steering response, brake function, and general chassis readiness, because all of those systems share the road load with the tires.

That routine is especially important on a brass-era Packard because touring reliability comes from the whole vehicle working together, not from tire condition alone. If the car has sat for a while, pay extra attention to pressure loss and sidewall condition before setting off. A short local shakedown run after inspection is often wise before committing to a longer event route, giving you time to catch any fitment or mechanical issue while still close to home.
