1958 Packard 58L-P8 Tires

The 1958 Packard 58L-P8 uses two primary bias-ply tire sizes: 710-15 and 800-14. Those are not interchangeable descriptions of the same fitment, because each size corresponds to a different wheel diameter and a different overall tire selection path.

The practical step is to verify whether the car has 15-inch or 14-inch wheels before choosing a tire. Once that is confirmed, the decision becomes more specific: blackwall, narrow whitewall, or wide whitewall appearance, along with the brand and tire series that best match the way the Packard is being restored, shown, or driven.

A 1958 Packard 58L-P8 can use either a 15-inch rim with 710-15 tires or a 14-inch rim with 800-14 tires. The wheel diameter is the key fitment detail because the two primary tire sizes are tied to different rims.

Checking the wheel itself is more useful than relying on assumptions, especially on an older collector car that may have had wheel changes over time. Once rim diameter is confirmed, compare wheel width, tire construction, and sidewall style so the replacement tire suits both the car’s setup and the appearance you want to maintain.

The 1958 Packard 58L-P8 has more than one tire size because its fitment can be based on different wheel diameters. In this case, 710-15 is the 15-inch fitment and 800-14 is the 14-inch fitment, with both remaining traditional bias-ply sizes.

That means the right choice is not made by picking the wider-looking number alone. The correct starting point is the wheel on the car now, followed by checking that the tire’s rim-width specification and overall presentation make sense for your Packard’s current setup, especially if it has been modified or restored with replacement wheels.

For the 1958 Packard 58L-P8, 710-15 is a bias-ply primary tire size. It is part of the car’s traditional fitment pattern and is available in classic bias-ply product lines from several vintage-focused brands.

A radial alternative can still be considered, but it should be treated as an equivalent option rather than the same thing as the original construction. Owners usually choose between staying with bias-ply for period-style appearance and feel or moving to a radial-equivalent size after confirming wheel compatibility, dimensions, and clearance on the actual car.

Radial equivalents for 710-15 include 205R15 as an 80-series metric radial, P215/75R15 as a 75-series P-metric radial, P225/70R15 as a 70-series P-metric radial, and 710R15 as a bias-look radial. Each option keeps the 15-inch rim diameter while using a different radial sizing convention or presentation.

Those choices give a buyer several ways to approach a radial conversion, from a more conventional metric radial to a bias-look radial that keeps a more traditional visual impression. The recommended rim-width range for these equivalents is 6-8 inches, and the final selection should be checked against wheel width, vehicle clearance, and the Packard’s current setup before changing construction.

A bias-look radial can be considered for the 1958 Packard 58L-P8 in both primary fitment paths. The available bias-look radial equivalents are 710R15 for 710-15 and 800R14 for 800-14, giving owners a radial-format alternative that aims to preserve a more traditional tire appearance.

That approach can appeal to buyers who want a collector-style look without staying strictly with bias-ply construction. Even so, the wheel diameter still has to match, and the tire should be checked against the wheel width and the car’s available clearance so the visual upgrade does not create a fitment problem elsewhere on the vehicle.

Choosing a 710-15 tire for a 1958 Packard 58L-P8 starts with confirming that the car has 15-inch wheels. From there, the main selection factors are bias-ply construction, sidewall style, brand, tire series, and whether the tire’s rim-width specification matches the wheel on the car.

This size is available in blackwall, narrow whitewall, and wide whitewall forms, so appearance can change the character of the Packard as much as the size itself. It also helps to compare load figures and basic tire weight when those details matter to your decision, especially on a large collector car meant for regular road use.

Tires for the 1958 Packard 58L-P8 are available in blackwall, narrow whitewall, and wide whitewall styles. Those choices appear across the two primary sizes, though the exact sidewall treatments vary somewhat between 710-15 and 800-14 depending on the brand and tire series.

Sidewall style has a major effect on the car’s visual presence, especially on a late-1950s Packard where the tire is part of the overall presentation. A buyer focused on understated looks may lean toward blackwall or narrow whitewall, while a more formal or restoration-oriented appearance often points toward one of the wide whitewall options.

The 1958 Packard 58L-P8 has tire options from BFGoodrich, Firestone, Goodyear, Universal Vintage Tire, and US Royal. Brand availability depends on size, with the broadest spread appearing in 710-15 and a slightly narrower but still useful range in 800-14.

Brand alone should not be the only deciding factor on a collector car like this. It makes more sense to compare the exact size first, then look at the tire series, sidewall treatment, rim-width suitability, and any available load information so the final choice matches both the car’s wheel setup and its intended appearance.

A period-style 1958 Packard 58L-P8 usually starts with the correct primary bias-ply size for the wheel on the car: 710-15 on a 15-inch rim or 800-14 on a 14-inch rim. From there, the visual character comes from the sidewall treatment and the classic tire series available in that size.

For many restorations, the bigger decision is not only size but how formal or understated the car should look once finished. Buyers who want to get closer to a historically appropriate presentation should compare surviving photos, marque references, and restoration documentation before settling on a specific whitewall treatment or blackwall appearance.

Tire construction changes the visual impression of a restored 1958 Packard 58L-P8 as well as its fitment options. A bias-ply tire keeps the car aligned with traditional late-1950s sizing and presentation, while a radial equivalent can change the look depending on the sizing format and sidewall design selected.

That is why many restoration-minded owners separate appearance goals from driving goals before making a final choice. A bias-look radial can help bridge those priorities, but it still needs to be evaluated as an alternative rather than assumed to mirror the original setup in every dimension or visual detail.

Modifications can absolutely affect tire fitment on a 1958 Packard 58L-P8. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body repairs can all influence whether a 710-15, 800-14, or any radial-equivalent alternative has the clearance it needs.

A collector car that left the factory one way may not sit the same decades later, so actual measurement matters more than assumption. It helps to confirm wheel diameter first, then look at wheel width, steering clearance, and fender space before mounting tires, especially when moving away from the original bias-ply construction pattern.

Before driving a 1958 Packard 58L-P8 on new tires, inspect the wheels for the correct diameter and sound condition, then confirm the tires are mounted and inflated properly. It is also smart to check valve stems, wheel hardware, visible suspension wear, and any signs that the tire might contact the fender or steering components.

The first few miles should be treated as a settling-in period rather than a full-distance road test. Pay attention to air loss, unusual vibration, pull, or rubbing, and recheck pressure after the initial drive so the car is ready for regular use without overlooking a simple fitment or installation issue.

Collector-car tires on a 1958 Packard 58L-P8 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Whether the car uses 710-15 or 800-14, owners should watch for sidewall cracking, tread damage, bulges, irregular wear, and slow air loss, especially if the Packard spends long periods parked.

Good maintenance also means protecting the car from prolonged sunlight, heat, moisture, and ozone exposure when possible. Even a low-mileage tire deserves routine inspection before road use, because age and storage conditions can matter as much as tread depth on a collector vehicle that is driven only occasionally.
