Cadillac 62 Series Tires

Cadillac 62 Series uses four tire sizes across its production run: 700-16 for 1940, 700-15 for 1941 and 1946-1947, 820-15 for 1948-1949 and 1954-1962 plus 1964, and 800-15 for 1950-1951, 1953, and many cars from 1954 through 1964. The 700-16 size fits a 16-inch rim. The other three sizes all fit 15-inch rims, with 700-15 generally shown on 5.00- to 5.50-inch rims and 800-15 and 820-15 commonly shown on 6.00- to 6.50-inch rims.

That spread means model name alone is not enough to order correctly. Start with the year, then confirm the wheel diameter on the car, and finally verify whether the car calls for the narrower 800-15 or the larger 820-15 where both appear in later production years.

On Cadillac 62 Series, 820-15 is a numeric bias-ply size. The 820 indicates a nominal 8.20-inch section width, with the decimal omitted in period tire sizing, and the 15 indicates that the tire fits a 15-inch wheel. Listed examples of this size are bias-ply tires, commonly paired with 6.00- to 6.50-inch rims and offered in blackwall, narrow whitewall, and wide whitewall styles.

That makes 820-15 a larger-section postwar and 1950s-era Cadillac size rather than a modern metric equivalent. If your Cadillac 62 Series falls in one of the years where both 800-15 and 820-15 are shown, verify the exact configuration and existing wheel setup before deciding which width and appearance best match the car.

Cadillac 62 Series uses two rim diameters across the years covered here. The 1940 model uses a 16-inch wheel with 700-16 tires, while 1941 and later fitments move to 15-inch wheels with 700-15, 800-15, or 820-15 tires. The rim-diameter change happens at 1941, and the later size choices remain within the 15-inch wheel family.

That early transition is the most important fitment checkpoint on the page. A 1940 car and a 1941 car are close in age but not in wheel diameter, so the easiest first step is to read the wheel size directly or verify it against the car’s original wheel set before looking at whitewall style or brand.

Cadillac 62 Series fitments here are all numeric bias-ply sizes, and the period-correct passenger-car offerings are tube-type bias-ply tires. That includes 700-16, 700-15, 800-15, and 820-15 in the classic bias-ply lines shown for this model. Tube-type construction is typical of collector fitments from this era and should be treated as part of the overall tire package rather than as an optional afterthought.

Tube choice should match the tire size and wheel condition, especially on original or restored rims. When a car has been sitting for years, inspect the wheel well, valve-hole area, and rim band condition at the same time, because a fresh tire mounted on a neglected wheel can still create preventable problems.

A 1958 Cadillac 62 Series falls into one of the years where both 800-15 and 820-15 are listed. Both are 15-inch bias-ply sizes, but they differ in nominal section width, with 800-15 representing an 8.00-inch section and 820-15 representing an 8.20-inch section. Since the wheel diameter stays the same, the decision is not about 15 versus 16 inches but about which of the two period sizes belongs on the specific car.

The practical way to sort that out is to inspect the existing tire size if the car has a known-correct setup, then compare the wheel width and restoration goals. Owners aiming for accurate presentation often also check factory literature, surviving original cars, or Cadillac specialists so the tire size, whitewall treatment, and overall stance all agree with the car.

Cadillac 62 Series tires are available in blackwall, narrow whitewall, and wide whitewall styles, depending on size. The 700-16 and 700-15 sizes include blackwall and wide whitewall options, while 820-15 adds both narrow whitewall and wide whitewall choices. The 800-15 products listed here are wide whitewall only, which suits the broad-whitewall look many collectors associate with 1950s Cadillacs.

Sidewall style changes the visual character of the car as much as the tire size itself. A restorer trying to match a luxury presentation will usually focus on whitewall width, while a more restrained or utilitarian look may point toward blackwall, particularly on the earlier sizes.

Cadillac 62 Series tires in these sizes come from Lester, Avon, BFGoodrich, Firestone, STA, US Royal, Universal Vintage Tire, and Coker Classic. Brand availability depends on the exact size, with 700-16 and 700-15 showing several traditional bias-ply and specialty offerings, 820-15 carrying the widest range, and 800-15 represented here by Coker Classic. Series names also vary by brand, including classic bias-ply, military, truck, and specialty performance lines.

Brand choice should come after fitment is settled. Once the correct size is established, buyers can narrow the field by sidewall style, intended use, and the kind of visual character they want, whether that means a conservative blackwall look or a period whitewall presentation more in keeping with a luxury Cadillac.

Cadillac 62 Series tires appear in several distinct series families, including Lester Classic Bias Ply, Silvertown Classic Bias Ply, Firestone Classic Bias Ply, US Royal Classic Bias Ply, Universal Classic Bias Ply, Coker Classic Bias Ply, Firestone Classic Military, Military NDT, Traxion, Super Transport, Transport Highway, Traction Mileage, Turbospeed Mk4, Dirt Track, and Dragster Cheater. Some are traditional passenger-car bias-ply lines, while others are military, truck, or racing-oriented tires that happen to share the same numeric size.

That matters because matching the size alone does not guarantee the right character for the car. A restored luxury Cadillac usually calls for a passenger-car bias-ply with the correct sidewall treatment, while military, truck, or racing series make sense only when the owner is intentionally building around a specialized look or use case.

A Cadillac 62 Series should be stored clean, dry, and out of direct sunlight, with the tires protected from ozone sources such as electric motors, welders, and battery chargers. Correct inflation during storage helps the carcass hold its shape, and a car that sits for long periods benefits from being moved slightly from time to time so one section of the tread is not carrying the load continuously. Bias-ply tires especially reward stable storage conditions.

Collectors who lay a car up for a season often place it on a smooth, dry surface and keep tire pressures checked rather than forgotten. If the car will remain parked for a very long stretch, include the wheels and tires in your routine garage walk-around instead of treating them as maintenance-free once mounted.

Tires on a Cadillac 62 Series should be inspected before every meaningful drive and more thoroughly at regular intervals even when the car sees very low mileage. Collector tires age by time as well as use, and bias-ply construction can hide early issues unless you look closely at sidewalls, tread, bead areas, valve stems, and inflation condition. Uneven wear can also point to alignment, suspension, or wheel-condition problems rather than tire failure alone.

A practical routine is to make the inspection part of your pre-drive preparation along with fluids, brakes, and lights. Cars that are shown more than they are driven still need that discipline, because long parked periods can create flat spotting, pressure loss, and age-related cracking that are easy to miss from a casual glance.

Tires on a Cadillac 62 Series should be replaced when age, cracking, hardening, impact damage, irregular wear, or structural concerns appear, even if the tread still looks deep. Collector-car tires often age out before they wear out, and that is especially true for lightly driven cars kept for shows, tours, or weekend use. Visual condition alone is not enough when the rubber has spent years under load and through temperature cycles.

Replacement timing should be guided by inspection history and the intended use of the car, not by tread depth alone. If a tire has an uncertain age or has spent years parked, have it evaluated before regular driving and err on the side of renewal when the car will be used beyond short local outings.

Cadillac 62 Series did not use one single size across its run. The period fitments represented here move from 700-16 in 1940 to 700-15 in 1941 and 1946-1947, then to 820-15 and 800-15 across the postwar and 1950s-1960s years. The available product families are primarily classic bias-ply passenger tires, which align with the type of construction collectors usually expect for a historically correct presentation.

Because several later years show both 800-15 and 820-15, originality should be checked against the specific car rather than the series name alone. Restorers pursuing factory-level accuracy typically compare the car’s existing wheels, original literature, and marque knowledge so the tire size and sidewall treatment match the year and presentation they are trying to recreate.

Correct tire fitment can affect both the visual credibility and judged authenticity of a Cadillac 62 Series. Size, wheel diameter, and sidewall style all shape how the car sits and whether it reads as properly restored for its era. On a prominent luxury car, an obviously incorrect tire profile or whitewall treatment can stand out quickly to informed observers.

That does not mean every owner needs concours-level exactness, but it does mean tire choice should support the car’s restoration goals. If the car is headed for formal judging, Cadillac club standards and marque specialists are the right references for deciding whether blackwall, narrow whitewall, or wide whitewall best suits the year and configuration.

Cadillac 62 Series restorations can be finished with blackwall, narrow whitewall, or wide whitewall tires, depending on the size selected and the period appearance being pursued. Early sizes such as 700-16 and 700-15 include blackwall and wide whitewall options, while 820-15 adds narrow whitewall choices and 800-15 is represented here with wide whitewalls. That range gives restorers flexibility across the prewar, immediate postwar, and 1950s Cadillac eras.

The right sidewall is usually the one that best matches the car’s year, trim character, and restoration intent. A restrained early-car look may lean blackwall, while many postwar luxury restorations benefit visually from whitewall proportion that complements the body and wheel covers rather than overpowering them.

These Cadillac 62 Series tires are intended for collector-car use and can be appropriate for public-road driving when the tires are the correct size, are in sound condition, and are paired with a mechanically healthy car. Most of the passenger-car offerings are bias-ply designs, which deliver period appearance and manners rather than modern radial behavior. Safety depends on the full system: tire age, inflation, tubes where required, wheel condition, steering, brakes, and suspension.

A freshly restored or newly acquired Cadillac should be treated cautiously until all of those basics are checked. Short local drives are a sensible way to evaluate how the car tracks, brakes, and rides before moving on to longer highway use.

Before driving a Cadillac 62 Series, check tire pressure, visible sidewall condition, valve stems, lug security, and any signs of flat spotting or damage from storage. Confirm that the car is wearing the correct wheel diameter and size for its year and setup, especially on 1940 versus 1941 cars and on later years where both 800-15 and 820-15 appear. Bias-ply tires also reward a quick look for uneven wear that could indicate underinflation or chassis issues.

The tire check should happen alongside a broader mechanical walk-around. Brakes, steering response, and wheel-bearing condition matter just as much as the rubber itself on a heavy vintage Cadillac, so road use should begin only after the whole car feels settled and predictable.

A Cadillac 62 Series on period-style bias-ply tires should be driven at speeds that respect the age, construction type, and overall condition of both the tires and the car. Even when the size is correct, a bias-ply collector tire does not react like a modern radial in emergency maneuvers, crosswinds, or abrupt lane changes. Smooth inputs and moderate cruising are part of driving the car as intended.

The sensible approach is to let the car’s condition set the pace rather than the posted limit alone. If the tires are recently fitted and the chassis is sorted, the car may be comfortable on ordinary secondary roads and touring use, but high-speed operation should never outrun the confidence created by inspection, setup, and real-world road testing.
