1963 Chrysler 300 Tires

The 1963 Chrysler 300 uses three primary bias-ply sizes: 800-14, 850-14, and 760-15. The Base model uses the 14-inch sizes, while the 300 H High Performance and 300 J use 760-15 on a 15-inch wheel.

That makes sub-model identification the first step before choosing a tire. A Base car may still need confirmation between the two 14-inch sizes, and any car with replacement wheels should have the actual wheel diameter checked before selecting a period-style bias-ply tire or comparing radial-equivalent alternatives.

A 1963 Chrysler 300 can use either a 14-inch or 15-inch rim, depending on the sub-model and tire size. The 800-14 and 850-14 sizes are for 14-inch wheels, while 760-15 is for a 15-inch wheel.

Wheel diameter is especially important here because the three tire sizes are split across two rim diameters. Measuring the actual wheel before ordering is the safest approach, particularly on cars that may have had wheels changed over the years or are being returned to a more restoration-oriented appearance.

More than one tire size appears on the 1963 Chrysler 300 because fitment changes across the model range. Base models use 14-inch bias-ply sizes, while the 300 H High Performance and 300 J use a 15-inch bias-ply size.

That means tire choice is tied to configuration rather than preference alone. The right approach is to confirm the exact sub-model, then verify the wheel diameter actually on the car, since older Chryslers are often restored, modified, or fitted with replacement wheels that may not match their original-era setup.

For the 1963 Chrysler 300, 760-15 is a primary bias-ply tire size. It is the size associated with the 300 H High Performance and 300 J, and the available products in that fitment are bias-ply tires.

A radial alternative can still be considered, but it should be treated as an equivalent rather than the primary construction. Buyers comparing a radial option should confirm wheel diameter, rim-width suitability, and clearance, especially if the car has been altered from its stock wheel or suspension setup.

Radial equivalents for 800-14 include 205R14 as an 80-series metric radial, P215/75R14 as a 75-series P-metric radial, P225/70R14 as a 70-series P-metric radial, and 800R14 as a bias-look radial. The recommended rim-width range for these equivalents is 5 to 7 inches.

Those options give different approaches to replacing a vintage numeric bias-ply size with a radial format. The key is not just matching the 14-inch wheel, but also checking the actual rim width, the car's clearance at steering and suspension travel, and the overall look you want the tire to maintain.

The primary fitments for a 1963 Chrysler 300 are bias-ply sizes, so staying with bias-ply construction keeps the original-era sizing format and traditional sidewall presentation. Radial equivalents are available for each primary size, which gives an alternative for owners who want a modern radial format.

The choice usually comes down to restoration priorities, wheel compatibility, and how the car will be driven. A period-style build often stays with bias-ply, while a road-use-oriented owner may compare radial equivalents carefully, making sure the wheel diameter, rim width, and available clearance all support the change.

Start with the fact that 760-15 is the correct primary bias-ply size for the 1963 Chrysler 300 H High Performance and 300 J. From there, the choice shifts to brand, tire series, whitewall width, and whether the car is being kept in a traditional bias-ply format or compared against radial-equivalent alternatives.

Available 760-15 products include offerings from BFGoodrich, Coker Classic, Universal Vintage Tire, and Goodyear, with several wide whitewall presentations and a narrow whitewall option. It also helps to compare rim-width details where they are given and to think about whether the car's look is more formal, sporty, or restoration-oriented.

Sidewall choices for 1963 Chrysler 300 tires include blackwall, narrow whitewall, and wide whitewall, depending on the size. The broadest sidewall variety appears in 800-14, while 850-14 is offered in narrow and wide whitewall versions and 760-15 centers mainly on whitewall presentations.

That makes sidewall style one of the biggest appearance decisions once the correct size is confirmed. A blackwall can give a more restrained look, while narrow and wide whitewalls move the car toward different period-style presentations, so the right choice depends on how the Chrysler is being restored, shown, or driven.

Tires for the 1963 Chrysler 300 are available from BFGoodrich, Goodyear, Coker Classic, and Universal Vintage Tire. Brand coverage varies by size, with 800-14 and 760-15 having the broadest assortment and 850-14 appearing in a more limited brand spread.

Brand is only one part of the decision, since the same size can still differ by tire series, whitewall treatment, rim-width specification, and load details where those are stated. Once the correct size is confirmed for the car, comparing those visible differences usually tells more than choosing by brand name alone.

A period-style 1963 Chrysler 300 usually starts with the correct primary bias-ply size for the exact sub-model: 800-14 or 850-14 for the Base model, and 760-15 for the 300 H High Performance or 300 J. Staying with bias-ply construction preserves the vintage sizing format and traditional sidewall profile.

After that, the decision becomes more visual. Whitewall width, blackwall versus whitewall presentation where available, and tire series all influence how formal, sporty, or upscale the car looks. When exact originality matters, the best finishing step is to compare your choice with marque-specific restoration references for your particular Chrysler.

Tire construction changes more than road feel on a restored 1963 Chrysler 300; it also changes the car's visual character. The original-style fitments are bias-ply sizes, and that construction keeps the tall, traditional sidewall presentation associated with full-size early-1960s American cars.

A radial equivalent may still be worth considering, but it can shift the look depending on the sizing format chosen. A bias-look radial stays closer to a vintage presentation where one is available, while metric and P-metric radials introduce a more modern sizing convention that some restoration-minded owners may want to evaluate carefully.

Yes, modifications can affect tire fitment on a 1963 Chrysler 300 even when the tire size itself is correct for the model. Replacement wheels, altered wheel width, suspension changes, ride-height changes, and body or brake modifications can all influence how a tire sits and clears.

That matters even more on a car with multiple original rim diameters across the model line. A Chrysler that now wears different wheels may need a closer check of wheel diameter, rim width, steering clearance, and fender space before choosing between original-size bias-ply tires and any radial-equivalent alternative.

Before driving a 1963 Chrysler 300 on new tires, inspect the wheels for the correct diameter and condition, confirm lug hardware and mounting surfaces, and make sure the tires are inflated properly for the intended setup. It is also wise to check for visible interference at the fenders, suspension, and steering components.

A collector car benefits from a broader walk-around as well. Look for cracked rubber parts, loose steering feel, uneven ride height, brake pull, fluid leaks, and any sign that the car has been sitting for long periods. A short, careful test drive can reveal rubbing, vibration, or alignment issues before regular road use.

760-15 tires on a collector 1963 Chrysler 300 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when tread wear is low, an older collector car tire should be watched for cracking, bulges, cuts, irregular wear, or slow air loss.

Storage conditions matter because these cars are often driven infrequently. Keeping the Chrysler away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tires, and moving the car periodically can reduce flat-spotting from long periods of sitting. Any change in vibration or handling deserves a fresh inspection before further driving.
