1964 Chrysler 300 Tires

The 1964 Chrysler 300 uses two primary tire sizes: 800-14 and 850-14. Both are bias-ply sizes built for 14-inch rims, and the correct one depends on the car's specific sub-model and setup. The Base & K Series can use either size, while the 300 K with Ram engine uses 850-14.

That means the first step is identifying the exact version of the car and confirming what wheels are actually on it today. Many collector cars have had wheels or tires changed over the years, so checking the existing rim diameter and the current tire size helps avoid ordering the wrong fitment.

The primary tire sizes for the 1964 Chrysler 300 both mount on 14-inch rims. Whether the car uses 800-14 or 850-14, the wheel diameter stays the same, so the fitment decision is about tire width and application rather than switching to a different rim diameter within the original tire-size range.

Wheel diameter is only part of the fitment picture, especially on a vintage full-size Chrysler. It is still important to confirm actual wheel width, because product specifications and radial-equivalent recommendations can vary, and a collector car may no longer be wearing its original wheels after decades of service or restoration work.

No. The 1964 Chrysler 300 does not use one universal tire size across every covered sub-model. The Base & K Series can use either 800-14 or 850-14, while the 1964 Chrysler 300 K with Ram engine uses 850-14. All of these primary fitments are bias-ply tires on 14-inch rims.

That difference matters because tire selection should start with the exact sub-model rather than the model name alone. Once the correct fitment range is confirmed, the decision becomes more specific: choosing the proper width, selecting a sidewall style that suits the car, and deciding whether to remain with bias-ply construction or compare radial equivalents.

For the 1964 Chrysler 300, 800-14 is a primary bias-ply tire size. It uses the vintage numeric sizing system common to the period, and it belongs to the original-style fitment family for this car rather than to the later radial sizing formats that many owners recognize today.

That distinction matters because staying with 800-14 bias-ply keeps the period construction and visual character of the car. A radial can be considered through one of the equivalent sizes, but that is a separate choice and should be checked against the car's wheel width, overall tire dimensions, and available clearance before making the change.

Radial equivalents for 800-14 include 205R14, P215/75R14, P225/70R14, and 800R14 as a bias-look radial. Radial equivalents for 850-14 include 215R14, P225/75R14, and P235/70R14. These options cover Euro-metric, P-metric, and in the case of 800-14, a radial built to preserve a more traditional bias-style appearance.

The practical difference is that these equivalent sizes use different sizing conventions and profile families, even though they are all meant to relate back to the original bias-ply fitments. A 5 to 7 inch rim-width range is relevant for these equivalents, so wheel width, section width, and body or steering clearance should be reviewed before switching.

That choice depends on what matters most for the car. Bias-ply tires keep the 1964 Chrysler 300 in its original construction style and are often preferred when maintaining a period-style look and feel. Radial equivalents are available for both primary sizes, giving owners another route when they want to consider a different construction.

A good decision starts with the car's intended use. A restoration-focused car may lean toward the original bias-ply presentation, while a road-driven car may lead an owner to compare radial alternatives more closely. Either way, the wheel size, wheel width, and clearances should be checked before changing from the original construction type.

Start with the correct primary size for the car: 800-14 or 850-14, depending on sub-model and setup. From there, the main selection factors are construction type, wheel compatibility, and appearance. On this Chrysler, the original fitments are bias-ply, so the choice often comes down to preserving that period-style construction or comparing one of the available radial equivalents.

After size is settled, compare the details that affect how the car presents and how the tire matches the wheel. Sidewall style, tire series, rim-width specification, and load rating all matter. A full-size Chrysler carries visual weight, so the right whitewall treatment or blackwall look can change the car's overall character noticeably.

Available sidewall styles for 1964 Chrysler 300 tires include blackwall, narrow whitewall, and wide whitewall, depending on the tire size and product selected. The broadest sidewall variety appears in 800-14, while 850-14 choices focus on narrow whitewall and wide whitewall bias-ply options.

That makes sidewall selection an important appearance decision, especially on a large 1964 Chrysler where whitewall width has a strong visual effect. Buyers aiming for a restrained look may prefer a narrow stripe or blackwall, while a more formal period-style presentation often points toward a wide whitewall. The best choice depends on the car's overall restoration direction.

Tires for the 1964 Chrysler 300 are available from BFGoodrich, Goodyear, and Universal Vintage Tire, depending on size. The 800-14 fitment has the broadest brand spread, while 850-14 choices are centered on BFGoodrich. Series names in this application include Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply.

Brand is only one part of the decision. It helps to compare each offering by size, sidewall treatment, tire series, rim-width specification, and whether the tire supports the appearance you want for the car. On a collector Chrysler, the right visual match can matter just as much as selecting the correct fitment category.

A period-style 1964 Chrysler 300 usually starts with the correct bias-ply size for the car, either 800-14 or 850-14. That keeps the original construction type and the vintage numeric sizing format that belongs to the era. From there, the visual direction comes from the sidewall treatment and the specific tire series available in that size.

The best period-style choice depends on whether the goal is a restrained blackwall look, a narrow whitewall presentation, or a fuller wide whitewall appearance. When exact originality matters at show level, it is worth checking marque references or restoration documentation for the car's configuration rather than assuming every available vintage-style tire matches the way it left the factory.

Tire construction changes both the visual stance and the overall character of a restored 1964 Chrysler 300. A bias-ply tire preserves the original-style sizing language and period presentation, which is why many restoration-oriented owners stay with that construction. Radial equivalents can alter the look even when they remain close to the original fitment intent.

That is especially important on a large 1960s Chrysler, where sidewall shape and whitewall treatment are easy to notice. An owner building a road car may still prefer a radial alternative, but anyone focused on restoration appearance should compare the tire's sidewall profile and styling carefully before changing construction away from bias-ply.

Yes, modifications can affect tire fitment on a 1964 Chrysler 300. Even when the car originally uses 800-14 or 850-14 on 14-inch rims, aftermarket wheels, changes in wheel width, suspension alterations, ride-height changes, or brake upgrades can change the amount of available space and the type of tire that can be used safely.

A collector car should never be judged by the model name alone if it has been updated over the years. Checking actual wheel diameter and width, along with inner and outer clearance at steering lock and through suspension travel, is especially important before moving to a wider tire or a radial equivalent.

Before driving a 1964 Chrysler 300 on new tires, inspect the wheels, valve stems, lug hardware, and overall tire condition once mounted and inflated. Confirm that the tire size matches the car's application, the beads are seated correctly, and there is no rubbing at the fenders, suspension, or steering components.

A short test drive should be followed by another visual check, because collector cars often reveal clearance issues only once weight transfers through turns and braking. It is also wise to verify pressure regularly, look for any sign of air loss, and recheck the tires after the first miles rather than assuming everything is settled after installation.

Collector-car tires in 800-14 or 850-14 should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Even a lightly driven 1964 Chrysler 300 can develop tire issues from age, long periods of inactivity, or environmental exposure, so tread depth alone should not be the only condition guide.

Look closely for sidewall cracking, bulges, cuts, uneven wear, and slow air loss, especially before a longer outing. Storage away from prolonged sunlight, heat, moisture, and ozone sources also helps protect vintage-style tires. A low-mileage collector car benefits from inspection on a schedule, not just when it is about to be driven.
