1966 Chrysler Tire Fitment Guide

1966 Chrysler vehicles use four sizes: 825-14, 855-14, 885-14, and 8.45-15. The 825-14 fits the Newport only, the 855-14 fits the 300, New Yorker, and Newport, the 885-14 fits the 300, New Yorker, and Newport, and the 8.45-15 fits disc-brake-equipped models. The 14-inch sizes mount on 14-inch rims, while the 8.45-15 uses a 15-inch rim. Rim-width fitment is established for the available 14-inch products, ranging from 5.00 to 6.00 inches depending on size.

That means a 1966 Chrysler owner should identify both the model and the wheel diameter before narrowing tire choices. A Newport has more than one possible 14-inch size, while a disc-brake application moves into a separate 15-inch fitment category. Once that baseline is confirmed, sidewall style and restoration goals become much easier to sort out.

On a 1966 Chrysler, 855-14 is a numeric bias-ply tire size. The 855 portion is the traditional nominal section-width code, corresponding to an 8.55-inch class size, and the 14 identifies the wheel diameter in inches. In this year and make, 855-14 appears on the Chrysler 300, New Yorker, and Newport, and the available products use bias-ply construction with narrow whitewall styling.

Numeric sizing can look unfamiliar if you are used to modern metric radials, but it is standard for many American cars of the period. For a 1966 Chrysler owner, the important takeaway is that 855-14 is a period-style 14-inch bias-ply fitment, not a modern metric equivalent. It should be matched to the correct wheel width and the specific model application before moving ahead.

No, 1966 Chrysler models do not all use the same tire size. The 300 and New Yorker share 855-14 and 885-14, the Newport can use 825-14, 855-14, or 885-14, and disc-brake-equipped models use 8.45-15. Even within one make and one year, Chrysler split fitments by model range and brake application rather than treating the full line as a single tire package.

That makes model identification more than a formality. A buyer who only knows “1966 Chrysler” still has several possible sizes, and the wrong assumption can put a 14-inch tire in place of a 15-inch fitment or confuse a Newport-specific size with a shared full-size size. Matching the tire to the exact model group is the cleanest way to avoid that mistake.

1966 Chrysler tire choices here center on blackwall and narrow whitewall styling. The 825-14 is available in both blackwall and narrow whitewall, while the 855-14 and 885-14 appear in narrow whitewall form. Those sidewall treatments fit the mid-1960s full-size American look well, especially on upscale Chrysler models where whitewall tires were a familiar visual feature.

Sidewall style is often the final detail that determines whether a car looks authentically restored or simply serviceable. A Newport owner may prefer blackwalls for a plainer presentation or narrow whitewalls for a more dressed-up appearance, while a New Yorker or 300 owner will often lean toward whitewalls to match the car’s more premium personality. Photos, factory literature, and marque specialists are useful when appearance matters as much as fitment.

BFGoodrich covers the available 1966 Chrysler products here, including 825-14, 855-14, and 885-14 bias-ply fitments. Those products appear within the Silvertown Classic Bias Ply line and include blackwall and narrow whitewall versions depending on size. No additional brand spread is present across the currently covered Chrysler sizes with product availability.

For a buyer, that creates a fairly focused decision process. Instead of comparing several manufacturers in the same size, the more meaningful choices are the exact tire size for the model and the sidewall style that best suits the car. On a 1966 Chrysler, appearance and proper application are likely to matter more than brand comparison because the construction family remains consistent.

For a 1966 Chrysler using 825-14, the BFGoodrich blackwall and whitewall versions share the same basic size, bias-ply construction, 14-inch rim diameter, 5.00-to-6.00-inch rim-width range, and 1620-pound load capacity at 32 psi. The main visible difference is sidewall treatment, with one offered as a plain blackwall and the others as narrow whitewalls. Weight varies slightly, with the blackwall at 23 pounds and the whitewall versions at 24 pounds.

That means the choice is mostly about presentation rather than a major mechanical change. A blackwall can suit a simpler, understated Newport look, while a narrow whitewall gives the car more of the dressed factory-era appearance many full-size mid-1960s Chryslers wore. If the car is being restored to a specific period look, the sidewall treatment is often the deciding factor.

Rim-width requirements for 1966 Chrysler tires vary by size. The 825-14 fits rims from 5.00 to 6.00 inches wide, the 855-14 fits 5.50 to 6.00 inches, and the 885-14 fits a 6-inch rim. All three of those sizes use 14-inch wheel diameters, while the disc-brake-specific 8.45-15 uses a 15-inch wheel diameter, though no rim-width range accompanies that size here.

Rim width matters because it affects how a bias-ply tire sits on the wheel and how correctly it presents on the car. Before selecting a replacement for a 1966 Chrysler, it is worth confirming the actual wheel on the car rather than relying on assumption, especially if the vehicle has been restored, modified, or mixed with parts from another full-size Mopar.

Original 1966 Chrysler wheels can only be shared across sizes when the wheel diameter matches the tire. The 825-14, 855-14, and 885-14 all fit 14-inch wheels, so those sizes stay within the same basic wheel diameter group. The 8.45-15 belongs to disc-brake-equipped models and requires a 15-inch wheel, so it is not part of the same interchange question as the 14-inch sizes.

Within the 14-inch family, wheel diameter alone does not settle the whole question because rim width still needs to match the tire’s approved range. A 1966 Chrysler owner moving among 825-14, 855-14, and 885-14 should verify the wheel width before assuming every 14-inch wheel is equally suitable. That extra check is especially important on cars that may no longer wear their original wheels.

A stored 1966 Chrysler should be kept out of direct sunlight, away from electric motors or other ozone-producing equipment, and in a cool, dry space with stable conditions. Bias-ply tires are especially prone to temporary flat-spotting when they sit in one position for long periods, so periodic movement or supporting the car appropriately during long storage can help reduce stress on the casing and sidewalls.

Tire care during storage is part of preserving how a collector Chrysler drives and looks. Keeping the tires properly inflated, rolling the car occasionally, and protecting the sidewalls from UV exposure can slow cosmetic aging and reduce the harshness many owners notice on the first drive after long storage. Good storage habits are often more important than mileage on low-use vintage cars.

On a 1966 Chrysler, tire life is usually judged more by age than by miles. Collector-car tires often see light annual use, so the safer rule is regular age-based evaluation at roughly five to seven years and serious replacement consideration as the tire approaches about ten years, regardless of remaining tread. The DOT date code on the tire is the best reference point for tracking age.

That matters because an older bias-ply tire can still look acceptable from a distance while the rubber and casing have already aged past their ideal service life. Owners who drive only to shows or on occasional weekend trips sometimes overlook age because wear is minimal. On a 1966 Chrysler, calendar time is the more meaningful measure.

Tires on a 1966 Chrysler should be inspected before every drive and again before any longer outing. Check sidewalls for cracking, cuts, or bulges, look for irregular tread wear, and confirm that each tire is holding pressure consistently. Because these are vintage-style bias-ply applications, close visual inspection is especially worthwhile after the car has been parked for extended periods.

A quick inspection routine can catch small issues before they turn into a roadside problem. On an older full-size Chrysler, it also makes sense to include the spare tire in that check so it is not forgotten until it is needed. Frequent inspection is one of the simplest ways to keep a collector car ready for dependable short-trip use.

A 1966 Chrysler Newport would originally have been associated with bias-ply tires, as that remained the standard American full-size practice in this period. Within the sizes covered here, the Newport uses 825-14, 855-14, or 885-14 depending on the application. Those are all period-correct numeric bias-ply formats rather than modern metric radials, which is the first major authenticity point for a mid-1960s Chrysler restoration.

If originality matters, confirming the exact Newport body style, equipment, and factory literature is still worthwhile because model families could overlap in size options. A marque club, restoration guide, or original owner documentation is the best way to settle a close authenticity question. Once the right size is confirmed, sidewall style becomes the next visual detail to match correctly.

Correct tire fitment absolutely matters when showing a 1966 Chrysler. Judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall style fit the era and the model’s expected presentation. A mid-1960s Chrysler wearing a modern-looking radial profile or the wrong sidewall treatment can look out of character even if the tire physically fits the wheel.

For most show settings, the closer the tire is to the proper period size and visual style, the stronger the overall impression of authenticity. A Newport, 300, or New Yorker may each carry slightly different expectations depending on trim level and market presentation, so event standards and marque-specific guidance are worth checking in advance. Tires are one of the easiest details to get almost right but not fully right.

For a 1966 Chrysler, 855-14 and 885-14 are both numeric bias-ply 14-inch sizes used on the 300, New Yorker, and Newport. The 855-14 carries a 1740-pound load capacity at 32 psi and fits 5.50-to-6.00-inch rims, while the 885-14 carries a 1860-pound load capacity at 32 psi and fits a 6-inch rim. Both appear with narrow whitewall styling in the available BFGoodrich offerings.

From a restoration standpoint, the choice is not about personal preference alone but about using the size that matches the car’s proper application. Even though both sizes belong to the same Chrysler family and share the same wheel diameter, they are not interchangeable on paper simply because they look similar. Matching the exact size keeps the car closer to its intended stance and presentation.

1966 Chrysler tires in the sizes covered here are vintage-style bias-ply fitments, and no speed-rating markings are present in the available products. That means highway use should be approached with the expectations appropriate to a period-style tire and a large 1960s car. In normal collector-car driving, the condition of the tire, correct inflation, and the overall mechanical health of the Chrysler are often just as important as the tire size itself.

A well-maintained 1966 Chrysler can be enjoyable on modern roads, but the driving experience will still reflect the era. Bias-ply tires typically track and respond differently than modern radials, and the car’s original brakes, suspension design, and weight should shape how it is driven at speed. Safe highway use starts with realistic expectations, fresh tires, and a sound chassis.

Available load-and-pressure figures for 1966 Chrysler tires vary by size and should not be transferred from one size to another. The 825-14 carries 1620 pounds at 32 psi, the 855-14 carries 1740 pounds at 32 psi, and the 885-14 carries 1860 pounds at 32 psi. Those figures describe each tire’s rated load at that pressure, not automatically the exact cold inflation setting Chrysler recommended for every model.

The best approach is to start with the factory recommendation for the specific 1966 Chrysler model, then compare it with the tire maker’s guidance for the reproduction tire being used. That keeps the decision tied to both the vehicle and the tire. Pressure tuning by guesswork can change ride, wear, and handling in ways that are especially noticeable on bias-ply construction.

Before a longer drive in a 1966 Chrysler, inspect every tire for cracking, cuts, bulges, exposed cords, uneven wear, and stable cold pressure. Check the valve stems, look over the spare, and make sure the tires have not developed severe flat-spotting from storage. On a full-size vintage Chrysler, that tire check should be part of a broader pre-drive review that includes brakes, steering, cooling, and fluid levels.

Longer outings place more heat and continuous load into a vintage tire than a short local trip, so small issues deserve attention before the car leaves home. A few minutes spent checking the tires can prevent an avoidable interruption and also reveal whether the car has been sitting too long between uses. Preparedness matters more with a 1966 Chrysler than with a modern daily driver.
