1962 Cadillac 62 Series Tires

The 1962 Cadillac 62 Series uses two primary tire sizes: 800-15 and 820-15. Both are vintage numeric bias-ply sizes designed for 15-inch wheels, and both appear within the covered fitment for the model. That means the car is not tied to one single primary size across every setup represented here.

The practical step is to confirm which size is already on the car and make sure the wheel remains a 15-inch wheel with an appropriate width for the tire being considered. On a restoration-minded Cadillac, the difference can also affect the final visual impression, especially once blackwall, narrow whitewall, or wide whitewall styles enter the decision.

The primary tire sizes used on the 1962 Cadillac 62 Series are built for a 15-inch rim. Both 800-15 and 820-15 share that same rim diameter, so the first wheel measurement to confirm is diameter rather than choosing between different rim sizes. That keeps the fitment question centered on tire size and wheel width.

A 15-inch wheel does not automatically answer every fitment question, because wheel width and the car's actual setup still matter when comparing products or moving to a radial equivalent. On a car that may have seen wheel changes over the years, verifying the wheel dimensions before purchase helps avoid choosing a tire that suits the nominal diameter but not the real wheel.

The covered 1962 Cadillac 62 Series 8 Cyl. fitment includes both 800-15 and 820-15 bias-ply sizes. Rather than pointing to one single size for every car, that means this sub-model can appear with either of the two primary 15-inch bias-ply fitments. The correct choice depends on the actual wheel and tire setup on the vehicle.

That matters because selecting by model name alone may not narrow the tire decision enough. Looking at the existing sidewall size, confirming the wheel diameter, and checking wheel width will do more to prevent a mismatch than relying only on the sub-model label, especially on an older Cadillac that may have been restored or altered at some point.

For the 1962 Cadillac 62 Series, 800-15 is a primary bias-ply tire size. It uses the older numeric sizing system associated with vintage American fitments and belongs to the car's traditional bias-ply tire profile. In this application, radial sizes are treated separately as equivalent alternatives rather than as the primary original-style construction.

That distinction matters because staying with an 800-15 bias-ply keeps the original sizing language and a period-style presentation, while moving to a radial involves comparing an equivalent size against the wheel and vehicle setup. Construction changes can also alter the character of the car, so appearance goals and wheel compatibility should both be part of the decision.

Radial equivalents for 820-15 include 235R15 as an 80-series metric radial, P235/75R15 as a 75-series P-metric radial, P255/70R15 as a 70-series P-metric radial, and 820R15 as a bias-look radial. Those options give the 1962 Cadillac 62 Series owner several ways to compare radial sizing while staying on a 15-inch rim diameter.

Each of those equivalents represents a different sizing convention or visual approach, so the choice is not just radial versus bias-ply. A recommended rim-width range of 6-8 inches is associated with the equivalent fitment, and the final selection should still be checked against wheel width, overall wheel setup, and clearance at the suspension and body.

That choice depends on what matters most for the car. The primary 1962 Cadillac 62 Series fitments are bias-ply in 800-15 and 820-15, which suit a traditional restoration-oriented approach. Radial equivalents are also available, including metric, P-metric, and bias-look radial options, so the car can be kept close to its vintage sizing convention or moved toward a radial alternative.

A buyer focused on period-style appearance often starts with bias-ply, especially when whitewall presentation is a major part of the car's look. A buyer considering regular road use may also look at the radial equivalents, but the decision should still include wheel-width confirmation, physical clearance checks, and a realistic look at how original the car should appear when finished.

Start with the basic fitment points: whether the car needs 800-15 or 820-15, whether the wheel is still a 15-inch wheel, and whether the goal is to keep a bias-ply setup or consider a radial equivalent. On this Cadillac, tire selection is as much about presentation as it is about basic sizing because whitewall treatment can strongly influence the finished look.

From there, compare the tire's construction, brand, series, sidewall style, and wheel-width compatibility. Some choices lean toward traditional classic bias-ply offerings, while others move into specialty territory. Matching the tire to the car's intended use, its existing wheel setup, and the kind of restoration appearance desired will narrow the field more effectively than choosing by size alone.

Available sidewall styles for 1962 Cadillac 62 Series tires include blackwall, narrow whitewall, and wide whitewall depending on the size and product chosen. The 800-15 options here focus on wide whitewall presentation, while 820-15 opens up a broader range of blackwall, narrow whitewall, and wide whitewall choices across several brands and tire series.

That matters because sidewall style can change the car's visual character almost as much as wheel and hubcap choice. A wide whitewall typically pushes the look toward a stronger period-style luxury presentation, while blackwall can feel more restrained. The best choice depends on the appearance being pursued, not just on whether the tire meets the basic size requirement.

Tires for the 1962 Cadillac 62 Series are available from Coker Classic, BFGoodrich, Firestone, US Royal, Universal Vintage Tire, and Avon. Brand availability varies by size, with 800-15 centered on Coker Classic and 820-15 offering the broadest selection across several classic bias-ply series and specialty applications.

Brand choice should be treated as part of a larger comparison rather than the only deciding factor. Once the correct size is confirmed, compare the sidewall presentation, tire series, construction, and wheel-width suitability within that brand's offering. On a car like this Cadillac, the right brand often comes down to the exact combination of fitment and appearance being pursued.

For a period-style 1962 Cadillac 62 Series, the natural starting point is one of the primary bias-ply sizes used on the car: 800-15 or 820-15, depending on the actual wheel and tire setup. That keeps the vintage numeric sizing format and the traditional bias-ply profile in place, which matters on a large early-1960s Cadillac where tire appearance is highly visible.

After size is confirmed, sidewall treatment becomes a major restoration decision. Wide whitewall options are available in both fitment paths, while 820-15 also adds blackwall and narrow whitewall choices. If exact originality matters beyond a period-style presentation, marque-specific references and vehicle history should guide the final style and brand selection.

Tire construction changes more than the way the car drives; it also affects the way the restored Cadillac looks. A bias-ply tire preserves the vintage sizing convention and traditional sidewall shape associated with the car's original era, while a radial equivalent can introduce a different visual impression even when it remains close in overall fitment intent.

That is why many restoration-minded buyers decide on construction before they choose brand or whitewall width. A bias-look radial can also be part of the conversation for someone who wants radial construction without moving too far from a traditional presentation. Either way, the wheel dimensions and the finished stance should be checked before committing to the change.

Yes. Even though the 1962 Cadillac 62 Series uses 15-inch bias-ply tire sizes, modifications can change what works on the actual car. Aftermarket wheels, altered wheel width, suspension changes, ride-height changes, or bodywork differences can all affect clearance and the way a given tire sits under the car, especially when moving between 800-15, 820-15, and radial equivalents.

That is why the current setup should be checked before selecting a replacement tire. Measuring the wheel, confirming the size on the sidewall, and looking at clearance at full steering lock and normal ride height can prevent problems. On an older car, the safest assumption is that the present configuration may differ from the one it left with decades ago.

Before driving a 1962 Cadillac 62 Series on new tires, inspect the wheels for correct diameter and condition, confirm the tire size matches the intended fitment, and check that all four tires are properly seated and inflated. It is also wise to look over valve stems, lug hardware, and general wheel integrity before putting a full-size collector Cadillac back into road use.

The vehicle itself deserves attention too. Steering components, suspension wear, brake condition, and alignment can all influence how a new set of tires feels once the car is moving. A quick walkaround should also include sidewall and tread inspection after the first short drive, along with a recheck for rubbing, uneven clearance, or signs of air loss.

Collector-car tires in 800-15 or 820-15 sizes should be maintained with regular pressure checks, periodic visual inspection, and careful storage habits. On a 1962 Cadillac 62 Series that may spend long periods parked, low use can hide aging problems, so sidewall cracking, flat spotting, cuts, bulges, and unexplained air loss all deserve attention even if tread wear looks minimal.

Driving the car occasionally, storing it away from prolonged heat and sunlight, and keeping it off surfaces that trap moisture can help preserve the tires' condition. The wheels should also be checked for cleanliness and corrosion where the tire seats. Any collector Cadillac that has sat for an extended time deserves a close inspection before a longer outing.
