1966 Chrysler Newport Tires

A 1966 Chrysler Newport uses 825-14, 855-14, or 885-14 tires, all in bias-ply construction on 14-inch rims. The exact size depends on the car's sub-model, so there is not one universal tire size for every Newport in the 1966 model year.

The practical first step is identifying whether the car is a Base, Wagon, or w/Air Cond. version, then confirming the wheel and tire combination already on the vehicle. Many full-size cars have seen wheel changes over the years, so matching the replacement tire to the actual rim diameter and the car's present setup matters just as much as knowing the model name.

The 1966 Chrysler Newport uses a 14-inch rim with its primary tire sizes. All three original-style fitments for this model range, 825-14, 855-14, and 885-14, are built around that same 14-inch wheel diameter.

That shared rim diameter simplifies the first part of fitment, but it does not mean every Newport should use the same tire size. Width and vehicle configuration still matter, and cars that have been fitted with later wheels should be measured rather than assumed. A quick check of the wheel stamping or the tire currently mounted can prevent ordering a correct size for the wrong wheel.

The 1966 Chrysler Newport has more than one tire size because fitment varies by sub-model and configuration. Base models use 825-14 or 855-14, while Wagon and w/Air Cond. versions use 855-14 or 885-14, so the covered Newport range does not share one single primary size.

That variation means the right tire decision starts with the exact version of the car, not just the year and model badge. Since all of these are 14-inch bias-ply sizes, the differences can look subtle at a glance. Verifying the actual tire code on the car and checking wheel width before replacement is the safest way to narrow the correct fitment.

For the 1966 Chrysler Newport, 855-14 is a primary bias-ply tire size. It uses the vintage numeric sizing format rather than a modern radial format, and it appears as one of the original-style 14-inch fitments used across several Newport sub-models.

That matters because keeping 855-14 in bias-ply form preserves the car's period-style construction and appearance. A radial alternative can still be considered, but the conversion should be treated as a change in tire type, not just a change in brand. Wheel width, actual tire dimensions, and clearance around the fender and suspension should all be checked before making that switch.

Radial equivalents for 825-14 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. These are alternative radial-format sizes associated with the original 825-14 bias-ply fitment.

Each option represents a different sizing convention and profile approach, so the choice is not only about construction. The recommended rim-width range is 5-7 inches, which gives a useful wheel-compatibility reference point. Before converting, compare the tire to the car's actual wheel width and check steering, suspension, and body clearance instead of assuming every equivalent suits every Newport setup.

Start by matching the radial equivalent to the Newport's original bias-ply size. A 825-14 tire can correspond to 205R14, P215/75R14, P225/70R14, or 800R14, while 855-14 can correspond to 215R14, P225/75R14, or P235/70R14.

After choosing the equivalent category, confirm the actual wheel width, since a 5-7 inch rim-width range is associated with those radial alternatives. It also helps to inspect front-end condition, suspension height, and body clearance before changing construction. A large, heavy full-size car like a Newport can react differently to a tire change, so the vehicle's present setup should guide the final decision.

Begin with the correct primary size for the car's exact sub-model, because the 1966 Chrysler Newport may use 825-14, 855-14, or 885-14. All three are 14-inch bias-ply fitments, so the first decision is fitment accuracy rather than brand comparison.

Once the size is confirmed, the real choice becomes appearance, construction direction, and wheel compatibility. Some sizes have blackwall and narrow whitewall options, and two sizes also have radial equivalents to consider. It helps to think about whether the car is being restored with a traditional look, driven regularly, or already fitted with different wheels than it would have carried in period.

Sidewall options for the 1966 Chrysler Newport include blackwall and narrow whitewall, depending on the tire size. In 825-14, both blackwall and narrow whitewall are available, while 855-14 and 885-14 are offered in narrow whitewall form among the applicable products.

That gives the buyer an appearance choice beyond simple fitment. A blackwall tends to create a more restrained, understated presentation, while a narrow whitewall adds visible period flavor without changing the tire's basic size or construction. The best choice depends on how the Newport is being presented and whether the goal is subtle road use, restoration-minded styling, or a more traditional full-size 1960s look.

The applicable tires for the 1966 Chrysler Newport are offered in the BFGoodrich Silvertown Classic Bias Ply series. That series covers the available 825-14, 855-14, and 885-14 products used for this model range.

Since the series remains consistent, the main comparisons shift to size, sidewall treatment, and wheel compatibility rather than choosing between multiple vintage-style product families. That can simplify the decision once the correct fitment is known. A buyer can focus on whether the car needs a narrower or wider of the listed Newport sizes and whether blackwall or narrow whitewall better matches the intended appearance.

A period-style 1966 Chrysler Newport starts with the correct bias-ply size for the exact sub-model: 825-14, 855-14, or 885-14. Staying with a vintage numeric bias-ply tire preserves the tire format and overall visual character associated with a mid-1960s full-size Chrysler.

After the correct size is established, sidewall style becomes the next appearance decision. Narrow whitewall is available across the Newport fitments here, and 825-14 also offers a blackwall alternative. Buyers pursuing strict originality should compare their car against marque references, period photos, or vehicle-specific documentation, since a period-style tire is not automatically the exact tire presentation every individual Newport originally carried.

Tire construction changes more than ride feel on a restored 1966 Chrysler Newport; it also changes the car's visual presentation. A bias-ply tire keeps the traditional vintage sizing format and contributes to the look most buyers expect on a large mid-1960s American car.

A radial alternative can be useful for some owners, but it often introduces a more modern sizing format and a slightly different visual impression. That difference matters on a restoration where wheel opening fill and sidewall character are part of the car's stance. If appearance is a major priority, construction choice should be made alongside sidewall style and the car's overall restoration goals, not as an afterthought.

Yes. Modifications can affect tire fitment on a 1966 Chrysler Newport even when the replacement tire is one of the correct original-style sizes. Aftermarket wheels, altered ride height, brake conversions, or suspension changes can change the space available around the tire.

That is especially important when moving between 825-14, 855-14, and 885-14 or when considering a radial equivalent. Checking actual wheel diameter and width is the first step, followed by a look at steering lock, inner-fender clearance, and suspension travel. A Newport that has been altered from stock should be measured as it sits rather than relying only on the factory-era fitment range.

Before road use, inspect wheel condition, valve stems, tire pressure, and basic clearance around the suspension and body. It is also smart to confirm that the new tires match the car's actual 14-inch wheel setup and that all four tires are the intended size for the Newport's configuration.

A full-size collector car should also have its steering and suspension condition checked so the new tires are not being asked to compensate for worn components. Look over the older spare as well, since it may be decades older than the road tires. A short, low-speed test drive can reveal rubbing, pull, or vibration before the car goes on a longer trip.

Tires on a 1966 Chrysler Newport should be maintained with regular pressure checks, visual inspections, and periodic review of tread and sidewall condition. On a collector vehicle that may sit for long stretches, age and storage conditions can matter just as much as mileage.

Keep the car away from prolonged sun, moisture, and ozone sources when possible, and inspect for cracking, bulges, cuts, or slow air loss before each driving season. It also helps to recheck wheel balance and alignment if the car develops vibration or uneven wear. Consistent maintenance is especially important on an older full-size car, where tire condition has a direct effect on ride quality and confidence.
