1947 Cadillac 62 Series Tires

The 1947 Cadillac 62 Series uses a 700-15 tire size. This is a numeric bias-ply fitment mounted on a 15-inch rim, and it is the primary size associated with the covered vehicle configuration.

That means the first step is confirming that the car still has its proper 15-inch wheels and has not been changed to a different wheel diameter over the years. Once the wheel size is confirmed, the real choice becomes selecting the right 700-15 tire style, such as blackwall or wide whitewall, and choosing a bias-ply series that suits the car’s restoration goals and intended road use.

The 1947 Cadillac 62 Series uses a 15-inch rim with its 700-15 tire size. Product offerings in this size commonly pair the tire with a rim-width range of 5.00 to 5.50 inches, which is useful when comparing wheel and tire compatibility.

Rim diameter needs to be confirmed before any tire purchase because a 15-inch tire cannot be safely mounted on a wheel of another diameter. Wheel width also matters, especially on older cars that may have had wheels swapped during restoration or long-term ownership, so checking the actual wheel on the car helps avoid problems with bead seating, appearance, and basic clearance.

Yes. The covered 1947 Cadillac 62 Series V8 uses the same 700-15 bias-ply tire size as the model core. That keeps sub-model fitment simple and avoids the need to sort between multiple primary tire sizes.

Even with shared fitment, it is still smart to inspect the actual wheel setup on the car before replacing tires. Older luxury cars are often restored, stored for long periods, or modified with replacement wheels, and any change in wheel width or diameter can affect which 700-15 product makes the most sense for appearance, service use, and proper mounting on the car.

Start with the correct 700-15 size and 15-inch rim fitment, then narrow the choice by construction and presentation. For the 1947 Cadillac 62 Series, the available options stay in bias-ply construction, so the biggest differences are sidewall style, tire series, and whether the tire is aimed more at classic passenger-car appearance or a more utility-oriented application.

Wide whitewall versions suit a formal postwar luxury-car look, while blackwall tires create a plainer presentation. It also helps to compare rim-width compatibility, load figures when they are given, and tire attributes so the selected tire matches how the car will actually be used, whether that is careful show use, local road driving, or a more utilitarian setup.

The 700-15 tire size for the 1947 Cadillac 62 Series is available in both blackwall and wide whitewall styles. That gives the car two distinctly different visual directions while staying within the correct primary tire size.

A wide whitewall generally supports the formal, upscale appearance many owners want on a postwar Cadillac, while a blackwall creates a more understated look. Sidewall choice does not change the need to verify rim diameter and wheel condition, but it does have a major effect on how finished the car looks, especially on a restoration where tire appearance strongly influences the car’s overall stance.

Available 700-15 tires for the 1947 Cadillac 62 Series come from Firestone, BFGoodrich, and STA. The selection includes classic bias-ply passenger-car styles as well as some utility-oriented bias-ply series within the same basic size.

Brand alone is only part of the decision. It is also worth comparing the specific tire series, sidewall treatment, and whether the tire is aimed at a traditional luxury-car presentation or a more truck- or service-style application, since those differences can change the look and character of the Cadillac even when the size remains 700-15.

A period-style approach starts with the correct 700-15 bias-ply size on a 15-inch rim. From there, most restoration-minded owners will focus on traditional passenger-car bias-ply options rather than utility-oriented versions, because the tire’s sidewall treatment and overall visual character matter as much as the basic fitment.

A wide whitewall often complements the formal look associated with a late-1940s Cadillac, while a blackwall gives the car a more restrained presentation. When exact originality matters, the safest course is to compare the tire choice against period photos, marque-club guidance, or restoration records for the specific car before deciding which 700-15 version best suits the project.

On a restored 1947 Cadillac 62 Series, construction affects both shape and character. The primary fitment is bias-ply, and that traditional construction helps preserve the visual profile associated with a full-size postwar luxury car using a 700-15 tire on a 15-inch wheel.

Appearance is also shaped by sidewall treatment, with wide whitewall and blackwall versions creating very different impressions on the same car. Construction should still be chosen with the wheel setup and intended driving use in mind, but from a restoration standpoint, staying with the proper bias-ply size is the clearest way to maintain a traditional period-style presentation.

Yes. Even though the 1947 Cadillac 62 Series uses a 700-15 tire on a 15-inch rim, modifications can change what actually fits the car safely and cleanly. Wheel swaps, wheel-width changes, suspension work, ride-height changes, and body or brake updates can all affect fitment.

A Cadillac that still uses its original-style wheel setup is simpler to match, but an older car should never be assumed untouched. Measuring the actual wheel diameter and width, then checking steering and fender clearance at full lock and full suspension movement, is the practical way to confirm that a 700-15 tire remains appropriate for the car as it sits today.

Before driving a 1947 Cadillac 62 Series on new tires, inspect the wheels for damage or heavy corrosion, confirm the 15-inch rim size, and make sure the tires are mounted and inflated properly. It also helps to check valve stems, lug hardware, and basic wheel security before the car goes back on the road.

The rest of the chassis deserves attention too, especially on a collector car that may have spent long periods parked. Steering play, brake condition, suspension wear, alignment concerns, and any sign of rubbing at the fenders or inner wheelhouse should be addressed early, since new 700-15 tires cannot compensate for problems elsewhere in the car’s road-going setup.

Collector-car 700-15 tires should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Bias-ply tires on a seldom-driven 1947 Cadillac 62 Series deserve close attention for cracking, cuts, bulges, uneven wear, and air loss, even if the tread still looks good.

Long periods of inactivity can be harder on tires than steady use, so the Cadillac should be stored away from prolonged sunlight, heat, moisture, and ozone sources when possible. Occasional movement, clean wheel surfaces, and periodic checks of overall condition help the tires stay serviceable, while any sign of age-related deterioration should be taken seriously before road use.
